|“||And now, Hamato Yoshi... DIES!!!||„|
|~ Super Shredder injuring Splinter.|
Shredder or The Shredder (real name: Oroku Saki) is the overall main antagonist in the 2012 Teenage Mutant Ninja Turtles cartoon on Nickelodeon. Like the comics, his real name is Oroku Saki. He and Hamato Yoshi (Splinter) used to be friends until the love of a woman tore them apart. During the fight, Yoshi's wife was killed and his baby daughter was lost. At the end of the pilot episode, "Rise of the Turtles," he watches the news in Tokyo, Japan after the turtles have made themselves known. He concludes that Hamato Yoshi was building his own army and is headed to New York City to exact his revenge. In the episode "City at War", Shredder is mutated.
He was voiced by Kevin Michael Richardson, who is also famous for voicing Captain Gantu from the Lilo & Stitch franchise and Goro from the Mortal Kombat movie. He also voiced Chairman Drek in the video game, Ratchet & Clank, Joker in the Kids WB show, The Batman, Darkseid in Superman: Shadow of Apokolips, Trigon in Teen Titans, and Trigon in Teen Titans Go!.
The Shredder is highly delusional, pretentious, and manipulative, bordering on the psychopathic and emotionless, he possesses a warriors mentality and unshakably determined in a quest for revenge against his former friend Hamato Yoshi. While he says differently, Shredder is a man with no honor whatsoever, having betrayed humanity by assisting the aliens, the Kraang invade New York only so he could fulfill his quest for vengeance against Yoshi and his turtle disciples. One of his own minions even commented that the aliens have no concern of human life only for Shredder to coldly reply, "nor do I" highlighting how cruel and dishonest he is.
Shredder is a man of means, he has a vast knowledge of martial art history and came in to the possession of the Kuro Kabuto which he wears as a helmet. He has an army of highly trained ninja warriors called the Foot Clan and assassins, he also appears to be very rich but this did not soothe his hatred. Shredder is highly spiteful, conniving, remorseless, vindictive, sadistic and cold-blooded as a seasoned warrior, he could mow down enemies without even blinking an eye and after his failure to kill Splinter he decided to spite him by abducting his newborn daughter, Miwa. He was a cunning mind and a liar, when he had given Miwa her new name Karai, he raised her in the belief that Hamato Yoshi had killed her birth mother when it was he who performed the act but it was accidental. Shredder is a highly deceitful and cunning person who could easily manipulate people toward his advantage or sacrifice people for his advantage.
The Shredder has a twisted sense of mercy while he was intolerant of his minions failing him he would not kill them but aggressively threaten if they continued to, so far the cruelest punishment he had served was mutating Stockman, Steranko and Anton Zec for continuously failing him. But despite this he bargained with the Kraang to find a cure for his mutated daughter.
While he is a very cold, violent, hardened, and contemptuous man, Shredder was in no way incapable of love, the very cause of his quest for revenge against Splinter was out of jealousy that his love Tang Shen preferred his friend Hamato Yoshi over him and then blamed Yoshi for her death despite that it was by his hands. Shredder also cares for his adopted daughter Karai, training her in his ways and after she was mutated he searched for a cure to her mutation. Perhaps Shredder's most prominent trait was his incapability to accept blame for himself and instead wanted revenge against the people he believed had wronged him. He truly believes that Tang Shen was stolen from him by Splinter and was virtual, hell-bent, forthright, constructive, wholehearted, and unhesitating, on killing Yoshi and his disciples, he also believes that it was Splinter who was responsible for her death and completely ignoring the fact that her murder was by his hand. Shredder also blamed Yoshi for Karai being mutated into a snake creature and disregarded the fact that he was the one who put the girl in danger and after she blatantly rejected him, Shredder still calls her his daughter and ignored her hostility and aggression towards him.
In the end, Shredder's desire for revenge proved to be too great and instead of working with Splinter to stop the destruction of Earth, he took the opportunity to kill him and didn't care that the world would have ended.
Abilities and Skills
His skills of ninjutsu is very high that is beyond than any other ninja couldn't reach since he been training for his entire life that he was able to become unbeatable for learning forbidden ninjutsu. So far, he was able to easily defeat all the turtles and for long brutal fight against Splinter who has the skills that is near.
His abilities are quite amazing for a human to have as shown that he has immense strength is munch stronger then average person as he can lift Splinter with only one arm. Even his strength was strong enough to battle large opponents like Leatherhead in a short fight. He was even able to kick and punch large mutations around.
His speed seemed to be unmatched for the turtles as Donny said it is "like he was everywhere at once" in combat, so he's proven to be munch faster than the Turtles.
Shredder's acrobatics seems to be very well adaptable in combat for reflex and his agility as shown by fighting against Leatherhead.
His stamina and endurance is also high for his age is enough that he was able to take the jaw strength of Leatherhead, but the type of armor that he wears could be very proactive for his body to take many blows of attacks. As for his stamina he was able to still fight back just shortly after he was defeated by Leatherhead. Having the battle against Splinter in the episode "The Invansion ", he used his special skill by using his fingers that is powerful enough to push opponents to the wall that can defeat most of his enemies, but Shredder was able to get back up to continue to fight Splinter until he reveal that his arm was wounded but he was still able to walk.
His stealth is very well to surprise his enemies as he was able to sneak behind Leo.
His Intelligence is quite high epidemically for combat and figure is many ways as he knew the Turtles live in the sewers, knowing Master Splinter was in New York training a team of Ninjas, and others.
The Shredder's first appearance was in Rise of the Turtles, as Master Splinter explained to Leonardo about his first failure, trying to protect his peacekeeping birth clan, called the Hamatos, and his family of the same surname from his adoptive brother-turned-vengeful rival, Oroku Saki (AKA, The Shredder). As they reached adulthood Saki and Hamato Yoshi (Splinter's original identity) competed over the love of a young woman named Tang Shen, whose decision to marry Yoshi drove Saki into learning of his true heritage and turn on his former brother in his home, causing it to burn to the ground. The debris collapsed and killed Shen, which infuriated Saki even more. Putting the blame on Yoshi, Shredder left him in his crumbling house, believing that Yoshi would eventually perish. However, fifteen years later, Shredder, who has recently restored his cannon-fodding birth clan, called The Foot, saw a televised news bulletin from America, which tells how "Ninjas" were in New York. As the bulletin continued, he caught a glimpse of a shuriken with Yoshi's insignia. Now realizing the status of his "old nemesis", Saki dons his helmet and leads the Foot to America, where he intends to visit an "old friend".
Though he had no actual appearance in Turtle Temper, the Shredder's reason for hating Yoshi was explained to a grumpy Raphael by Splinter, who was explaining how careless decisions of anger could jeopardize the people around him. Since Tang Shen was in love with Yoshi, Saki was overcome with jealousy, so he approached the two one day, and pointed out many harsh and violent words at Yoshi, insulting him to the point of uncontrollable rage. Yoshi stopped Saki with a violent attack that left him limping away, and since that day, Yoshi and Saki's rivalry became a bond of hatred. Splinter never forgave himself for acting so careless. Losing his temper was the reason Oroku Saki destroyed his family, and his normal life.
In New Friend, Old Enemy, Shredder appears before his greatest pupil, Chris Bradford, and alerts him to Hamato Yoshi still being among the living. So he assigns Bradford with the job of eliminating Yoshi and his disciples. However, he was required to work alongside Shredder's street contact, Xever Montes.
In Never Say Xever, Bradford returns to his master and reports his failure, AND that Yoshi's disciples were actually "man-sized" turtles. Disappointed by Bradford's failure, the Shredder decides to have him follow Montes instead, hoping that the outcome will be different. However, the results were the same, and Shredder could not accept his minions' lack of victory. So he announces that he will deal with the Turtles himself .
In The Gauntlet, Shredder is disappointed at his two pupils for failing him, and lets his pet dog, Hachiko, bite Bradford's hand, and the Shredder explains that the dog wasn't pleased with him, nor was his master. Shredder's words of disappointment towards Bradford and Montes were as painful as Hachiko's teeth, going so far as to telling his pupil that he shamed his master with his incompetence even after every lesson and secret he shared with him, and he then cursed Montes, wishing that he never released the hoodlum from prison. The Shredder's words burned inside Bradford's mind, making him want to finish the Turtles off even more. And when the Foot reported to him about the Turtles current location, he and Montes followed them, hoping to please their master by killing the Turtles once and for all. After Bradford and Montes were washed away by the Mutagen inside a bomb, the Turtles celebrated their victory over them, but were shocked to hear a booming voice..."Your skills are impressive...but they will NOT save you." The Shredder made his presence known, making it all the more obvious that he is there to kill them. They all attacked him one by one, but he easily batted them back. He was proven not to be invincible though, as they managed to get in a few good hits each (Donatello most notably), and Michelangelo managed to hang him by his arm with the use of his nunchaku, though not for more than a few seconds. After Shredder defeated Donatello, Raphael, andMichelangelo, he grabbed Leonardo and demanded to know Splinter's whereabouts, promising that if Leo complied, he would not die with suffering. Shockingly, Shredder released the Turtles' leader when he saw Montes and Bradford changed into mutant animals. Though Shredder was terrified (and it is implied that he was even concerned) by this new surprise, he still intended to interrogate the Turtles, but they were already gone. He roared at his loss and confusion.
In Panic in the Sewers, Splinter has a nightmare about the Shredder killing the Turtles one by one, so the wary sensei takes matters into his own hands by training the Turtles further and restricting their right to leave the lair and play their games. Meanwhile, Shredder orders Bradford (whom Mikey dubs Dogpound, because of his new dog-like form) to take command of the Purple Dragons and a pair of Foot Ninjas, and locate a tanker truck of chlorosulfonic acid. After a few hours, Bradford reports how the Turtles defeated them with "go-karts and a water balloon." Before Bradford could make an excuse, The Shredder sliced off a part of his seemingly unbreakable spikes, indicating that Shredder is now tempted to kill his pupil if he fails him again.
In Mousers Attack!, Dogpound proves useful to the Shredder as he reported the Purple Dragons agreement to increase the Foot Clan's cut to 80% with 'no complaints'. Montes (stuck in a tank of water, due to his new fish-like form) yells out his frustrations about how useless he is in his current body. Dogpound and Shredder agree with him, but Shredder is quick to threaten Dogpound for the price of another loss...his legs. However, Dogpound is quick to change Shredder's mind. The feral hound brings over Baxter Stockman, whose creations, the Mousers, cost The Shredder his chance of finding the Turtles' base. Shredder, of course, blames the scientist, but he also finds a use for him and his talents at technology. So, he spares Stockman in exchange for the latter's services...
In New Girl in Town, Shredder is not pleased with Karai's failure in killing Leonardo and tells her that the next time she must finish him off or else.
In The Alien Agenda, Shredder's patience is wearing thin when Stockman failed in his attempt to build mechanical legs for Montes. When Karai came with information about the Kraang, Shredder dismissed it and told her to focus on her mission to destroy the Turtles and their master. When Karai brought a Kraang droid, which proved useful, Shredder was pleased and wanted Karai to find out everything she can about the Kraang.
In Baxter's Gambit, Shredder for the first time does not act out so much in this episode, but he gives Stockman permission to set out a trap for the Turtles, unaware it was also for Dogpound and Montes (whom Mikey recently dubs Fishface, because of his new fish-like form) as well.
In Enemy of My Enemy, Shredder ignores Karai's warning about the Kraang Invasion, since he is more focused on a weapons trade he has planned with his weapons dealer and mafia business partner, Ivan Steranko. He faces the Turtles once more, is saved twice by Karai, and manages to capture a Kraang.
In Karai's Vendetta, Shredder interrogates the captive Kraang. He threatens to kill the Kraang with one of his blades unless he tells him what he needs to know. The Kraang tells him that the reason they are trying to destroy the Turtles is because they are protecting the Kraang's main target; April O'Neil. Shredder then orders Karai to capture her.
In The Pulverizer Returns, he decides to obtain mutagen from the Kraang so that he can transform some of the Foot Soldiers into mutants, though warned by the captive Kraang operative of unpredictable results. After the Turtles thwart the plot, the captive Kraang operative tells Shredder that they have a common enemy in the Turtles and thus an alliance was born.
In Operation: Break Out, at TCRI, Shredder tells the Kraang that the Newtralizer nearly interfered in the plan. However, the Kraang remarks that it didn't prevent Kirby O'Neil from being taken (which was part of their plan to find the turtles' lair and April). Shredder then says that vengeance will soon be theirs.
In Booyaka-Showdown, Part 1 and Part 2, Shredder abducts April O' Neil and forces Splinter to duel with him. Splinter later finds out that the April that Shredder "abducted" is just a hologram. When Shredder finds out that Splinter is now a rat, he laughs, saying that he is "a rat caught in his trap". He then reveals that he only need April as bait to lure him out and now that he had, he had no use of April so he handed her over to the Kraang. Splinter battles the Shredder at the Foot Clan's hideout. Shredder later reveals sometime into the battle that Karai is in fact Miwa: Splinter's supposedly dead daughter. During the battle, Splinter, in a new flurry of rage, knocks off Shredder's helmet, to reveal the latter's horribly burned face, and moved in for the finishing blow. This was prevented by Karai, however. Shredder informs Karai that the rat is Hamato Yoshi, the man that he had told her had killed his mother, which happens to be another lie fed to her by her false father.
In The Mutation Situation, Shredder can be seen in his lair, approving The Kraang's plan of creating an ape-like creature to attack the turtles. However, after The Kraang's plan fails, Shredder informs Karai that since the aliens are of no use to him now, he will begin to develop an army on his own.
In Follow The Leader, Shredder tests his new robotic foot soldiers built by the Kraang (which indicates that the Kraang are still in fact still useful to him, and their alliance still stands) by having them fight Karai. He then leaves for Japan to take care of an "urgent matter", while he tells Karai not to make any move on the turtles while he is gone.
In Target: April O'Neil, He speaks to Karai through a mouser projection screen [for he's still in Japan]. He is very angry at her for disobeying him and his orders after she went after the Turtles and failed miserably. Karai states that the Kraang have made improvements to the Footbots which she blames for the Turtles escape, so Shredder then cuts her off and orders her to not have any more dealings with the Kraang until he returns. He then threatens to her punish her should she disobey him again and he assures her the consequences will be severe. He then signs off.
In The Manhattan Project, Shredder brings Tiger Claw onto his team and makes him his second-in-command. Karai is appalled by this, saying that she earned this position fair and square. Shredder then sends Tiger Claw off to find & abduct Splinter and the Turtles, commanding Karai to follow Tiger Claw's every order. After the capture of Splinter, Shredder enters the lair, along with Karai. He tells both Dogpound (whom Mikey recently dubs Rahzar, because of his new near-skeletal form) and Fishface that they must leave the area for the time being. Afterward, he immediately approaches Splinter and purposely tries to exacerbate things by telling him that he has grown to be 'a wretched rat-man only waiting to be put out of his misery'. Splinter retorts that, at least he is not someone who wears a mask, hiding the low amount of humanity that they have left. Shredder says that Splinter is the one and only reason that he wears his signature helmet. The Shredder then extends one of his gauntlets and prepares to kill his mortal enemy. However, Karai halts his horrible action. Shredder asks why she would dare to try and stop him, to which Karai replies that executing a sworn enemy while the latter is poisoned and chained is just improper. She then recommends allowing Splinter to perish with the slightest bit of honour and in a combat situation, preferably. Tiger Claw ends up siding with Karai on this one. Thus, Shredder offers Splinter one last chance to inhale and exhale before fighting with him. Meanwhile, Leo is climing up the side of the Foot Headquarters with the usage of Tegaki. After destroying a couple Footbots that were put on gaurd, he successfully gains entry into the building and jumps down several platforms until he has reached his sensei. However, the throne room is then lit up with dozens of orange lights at the sidelines, and this is when the Shredder appears from behind his throne. Just when Leo is about to pull out his twin weapons, Tiger Claw (along with the Rahzar, Fishface and Stockman) appears and twists his arm, disarming him and knocking him onto the floor. The Shredder then asks where the other three Turtles are, but Tiger Claw, using his very keen sense of smell, says that he senses no one else in the area. The Shredder then removes his own cape, breaks the bindings around Splinter's arms, and instructs Leo to watch in horror as the retribution with Splinter is finally carried out to the end. In spite of being poisoned, Splinter is actually able to avoid just a few of Shredder's attacks, but Yoshi is then kicked hard in the torso, sending him flying a good length of the way across the room. Shredder then picks him up and is about to put him out of his misery for certain when yet another earthquake occurs, catching the Shredder and his henchman off-guard. Not only that - but our heroes then enter, armed with some handy fire crackers, which they actually use to distract the ' attention and escape with their sensei.
In The Lonely Mutation Of Baxter Stockman, Shredder and Rahzar walk into Stockman's lab, scolding Stockman for creating a bunch of useless mutants, including a duck. Stockman explains that it swims, flies, and knows Taekwondo, but this is obviously not enough to please Shredder, so he then says that he has devised plans for pigs and rhinos, but this still doesn't get himself off the hook. Shredder knows that Stockman has failed him one time too many, and Rahzar begins approaching the scientist with the intention of severely harming him, but Shredder has a much more suitable fate in mind - mutating Stockman. Shredder presses a button on the controller that triggers the bottles on Baxter's neck brace to crack, slowly spewing the contained Mutagen all over him. Shredder and Rahzar then leave him behind to mutate. Later, the Footbots drag a dazed Stockman-Fly all the way back to the Foot HQ. They then pause and Rahzar approaches. He says that he wants to squish Stockman here and now, but Shredder has "other plans". Shredder then says that Stockman will need to create one last Mutant to be evaluated—and if he messes up, the villain will pluck his wings. Knowing that his hateful life will continue from this point, Stockman-Fly thanks Shredder for his 'generosity', while Rahzar tosses a chocolate bar for Stockman-Fly to eat.
In The Wrath of Tiger Claw, Shredder sees Karai looking at a photo of her mother and asks what troubles her. Karai asks him to tell her the truth about Hamato Yoshi, Shredder tells her that he is responsible for the death of her mother just as Tiger Claw enters the room. Tiger Claw explains how he crossed different dimensions to return so he could have is revenge against all those who have wronged him. Shredder tells Tiger Claw to go after the turtles and and destroy them despite Karai's objections, he orders her to go with him.Tiger Claw brings Karai before Shredder, telling him of her betrayal. Karai demands that he tell her the truth about Splinter to which Shredder finally admits that she is Hamato Yoshi's daughter. Shredder then tells Tiger Claw to take her away, locking her away in a cell.
In The Legend of the Kuro Kabuto, Shredder visits Karai in her jail cell explaining why he kept her real father a secret and hopes that she will one day understand what he had to do. After Shredder's helmet called the Kuro Kabuto is stolen by Steranko's master thief, Anton Zeck, on his boss's behalf, Shredder finds his calling card on a glued-down Rahzar and orders him to get him everyone. After explaining the history of the Kuro Kabuto, Shredder orders his minions to hunt for Zeck (Fishface is sent with Stockman-Fly while Rahzar is sent with Tiger Claw). When Leonardo confronts Shredder for a trade, he kept him busy long enough for the others to get to Karai. Shredder managed to get the Kuro Kabuto back upon the Turtles' retreat. The Karai that was traded later turned out to be a bomb as the Turtles evade it.
In Vengeance is Mine, Shredder appears and orders Tiger Claw to spare Karai's life. Tiger Claw agrees and, later, Karai awakens with chains around both of her wrists, while Shredder is standing behind her. Shredder takes off the lower part of his mask and asks why Karai has insisted on trying to hurt him. Karai refuses to speak, causing Shredder to ask why 'his daughter' does not have a thing to say. Karai harshly scolds him and, at the top of her lungs, yells that she is not his daughter. As Karai escapes, she looks up to see Shredder staring down at her from the top of the building with an enraged look in his eyes. Tiger Claw reports back to Shredder, stating that he has searched the city in search of Karai and that he has ordered some Footbots to continue the search and to return with every detail. After Tiger Claw reveals that he hasn't had any luck yet, Shredder tells his minion that his efforts are pointless and that Karai's escape was to be counted on. He then goes on to say that Karai will most likely arrive with Splinter and his pupils to finish what they have started, which will allow the Shredder to have his vengeance. Shredder then commands Tiger Claw to inform Stockman-Fly of the situation. Breaking back into Shredder's headquarters, Karai notices that her former 'father' seems to be resting in his throne, but, after coming closer, it is then revealed that Shredder has put Chrome Dome there instead. She is then nearly captured by the robot, but manages to stab it through the chest before it can possibly inflict any harm. Shredder then emerges from the shadows and says that she has returned sooner than expected. She then confronts Shredder in combat, vowing to give him a final goodbye. However, Shredder quickly tells her that the mistake she's made is foolish and that he has taught her everything she has come to learn. Shredder then brings his blade up close to her neck and has her handed over to a massive hoard of his own henchmen. Karai is then taken away so that a mysterious experiment can begin.Inside Stockman-Fly's new lab, Shredder walks in and it is soon revealed that Stockman-Fly was told to extract a large portion of DNA from a serpent and place it inside of his vat filled with Mutagen. Shredder then orders his men to have Karai bound to a table within a cage hanging over the vat. Tiger Claw remarks that Shredder is pretty ruthless if he's wanting to mutate his own 'cub', but Shredder replies that Karai becoming a Mutant is not his actual intentions. His plan is that, when the Turtles attempt to save Karai, he drop them into the Mutagen, and this will cause them to become brainless serpents that will immediately start to target Splinter. Therefore, the latter would be left mortified and this is when Shredder would get the chance to 'shatter' his body. However, what Stockman-Fly did not reveal is that, the split second before Shredder entered, a different substance was accidentally spilled into the jar that is containing the modified Mutagen. Regardless, he states that everything has been prepared perfectly. During the next moment, Splinter and his sons all jump down from the cieling. It is not that long before Donnie, Mikey, and Raph are all trapped inside of spring-loaded cages that were set on the floor, while Master Splinter is restrained by ropes thrown onto him by the Footbots. Leo is also tossed into a cage by a Foot-Bot, but, luckily, just as the cage detracts, he slips a part of his Katana into an opening and this lets him pry his way out. He then jumps up and over the vat in order to reach Karai. He removes the gag from her mouth and she thanks him. However, Shredder then tries to stab Leo from behind, but Leo ducks and Shredder's gauntlet accidentally cuts through the chain that is holding up Karai's cage. Leo and Shredder both jump clear of the vat, but Karai's cage drops, and sinks deep into the Mutagen, as Master Splinter observes this in sadness. As a now mutant serpent Karai makes her way out of the Mutagen, Shredder is also filled with remorse. Shredder immediately tries to pin the blame on Splinter for Karai's mutation, and he charges off to finish his foe, only to be stopped when a large piece of the ceiling caves in and prevents him from continuing further. Tiger Claw says to Shredder that they have won this fight and should retreat proudly. Shredder is angry when he hears these words, as he does not feel like he has won at all and vows to avenge Karai, before disappearing into the debris.
In The Invasion, Shredder is seated on his throne, remembering Karai as a human and his pride in her skills as a ninja. Tiger Claw then enters the room, asking the Shredder if he's made up his mind about a deal with the Kraang. The Shredder states that he does accept their alliance with the Kraang, as they have provided the Foot Clan with alot of Technology and have asked for little in return. Tiger Claw questions the Shredder's decision because the Kraang will most likely betray him, as they have no care for the human race. The Shredder states that he has no regard for it, either. Kraang Prime then contacts the Shredder, asking for a decision as well. In exchange for the Kraang to reverse Karai's mutation and 'deliver' Splinter and the Turtles to the Shredder, the Shredder will then help the Kraang take over New York and the world. As chaos erupts during the Kraang invasion, watches it with his disciples. He gets word that Leonardo is moving in their direction. The Shredder prepares an ambush for him. Leo battles the Shredder's Footbots. He demands the Shredder to face him, but the Shredder denies this, stating that Leo is beneath his abilities. Leo begins to tire from the Footbots' attacks, but the Foot do not let up. Tiger Claw asks the Shredder if he can finish Leo off and the Shredder tells him not to do it yet, as he wants to see Leo suffer.Leo fights off more Footbots at the construction site and loses both his katana in the process. When his enemies seem to be defeated, Leo pauses, but a Foot-Bot on the ground grabs his leg and Leo loses balance, causing him to roll down the embankment and into the ice water collected in the pit below him. Leo soon comes out of the water, chilled and exhausted, but is unwilling to flee from his enemies. The Shredder then gives Tiger Claw, Rahzar and Fishface the go-ahead to attack Leonardo, and they do so. Leo fights them off and, amazingly, he defeats all of them, but the Shredder then slashes him across the chest, causing Leo to fall completely unconscious. Tiger Claw picks up the battered and senseless Leo and looks at his T-Phone, seeing the text messages from Mikey telling Leo to come to April's home. The Shredder demands his minions to draw every one in the apartment out by throwing in Leo. As Tiger Claw and the others leave to do this, the Shredder is confronted by Splinter, who demands to know where Leo is. The Shredder states that he has 'taken' Leonardo much like he took Miwa from Splinter and then they Fight.the Shredder states that Splinter is weak, while the Shredder is still strong with his rage. After Splinter knocks down the Shredder, however, Splinter tells him that anger is something that doesn't last. The Shredder ignores Splinter's wisdom and kicks him against a machine, causing lead pipes to fall on top of him. As the Shredder is poised to drive his gauntlets between Splinter's eyes, Leatherhead leaps on top of the Shredder and grabs him inside of his jaws, trying to crush him. However, the Shredder also defeats him and kicks him down into the water at the bottom of the pit. Now, full of righteous anger, Splinter starts to battle the Shredder with newfound strength and they both fall into the pit after Leatherhead. Splinter and the Shredder continue to fight in the sewer, April, Donnie, Mikey and Raph follow April's vision to the end of at drain pipe where they are trapped behind bars and only able to watch and shout words of encouragement to Splinter as he fights with the Shredder. Although Splinter is able to send his enemy flying through a wall, the Shredder strikes him down and turns a nearby wheel, activating a whirlpool that he throws Splinter into. This enrages Raph beyond words. The Shredder then leaves and Raph is angry beyond words, calling the Shredder a monster.
In Vision Quest, he appears in the spirit realm as Leonardo's opponent. At first, he overwhelms him by attacking the injured leg and being able to snatch the twin katanas welded. Leo is nearly defeated until he realizes the pain is all in his mind, leading to him to finally take the Shredder on. Shredder then grows to a giant size and is able to grab Leo, but is defeated upon Leo escaping his clutches and shooting him with an arrow to his burnt eye. Following this victory, Leo states that one day he'll beat him in the real world.
In Return to New York, he warns Tiger Claw to watch his tone, and reveals he knows much more about the Kraang's plan. For some reason, Shredder had other plans. He decides to destroy the Kraang and take over the city himself when the time is right. While telling Tiger Claw to continue his search for Karai, the Footbots arrived in with Splinter (who's lost his mind from the injuries). He has Stockman-Fly to place him in a containment unit to have his memories restored. Later, when Mikey accidentally sets that alarm on, Shredder and his gang arrive in to see the Turtles, Casey and April with Splinter, who's mind has been restored. Shredder has his clan to go after them, but they quickly get out with the help of ninja smoke bombs.
In Serpent Hunt, Shredder has Rahzar and Fishface continue their search for Karai. At the docks, he discovers Zeck was employed Steranko to steal his helmet, but Steranko arrives with a restrained Karai, who he promises to get back to Shredder in exchange for a way out of the city safely. After Karai and the Turtles escape, Shredder becomes furious at Zeck and Steranko for attempting to steal his helmet and hunting Karai, and proceeds to have them both mutated in Stockman-Fly's lab, despite Steranko's pleads for forgiveness, since they've known each other for about 10 years. When Stockman-Fly adds warthog DNA in the first batch of mutagen, Shredder orders Fishface to have Zeck to be mutated first for stealing the Kuro Kabuto. After Zeck is mutated, Shredder then has Stockman-Fly add rhinoceros DNA in the second mutagen batch to have Steranko mutated for his betrayal. He tells Steranko that his animal (the rhinoceros) is apropos. Steranko still tries to convince Shredder he would be better for him as a human, but Shredder, still ignoring his pleads, nods at Rahzar, who kicks Steranko in the second mutagen batch.
In The Pig and The Rhino, Zeck and Steranko attack Shredder for mutating them but he easily defeats them and makes them his new servants. He orders them to find Karai again or else he will further injure them. Despite the two (whom Mikey dubs Bebop and Rocksteady, because of their new warthog-like and rhino-like forms) originally disobeying him to go after the Turtles, they end up capturing Karai and bring her to his lair. Shredder vows to cure Karai and have his revenge on the Turtles.
In Casey Jones Vs. The Underworld, he is seen watching Karai in Stokman's lab, then later meets with Don Vizioso, an Italian crime lord. After mentioning how he controls the Russian Mob through Rocksteady, the Asian gangs through Hun and the rest of the Purple Dragons and the South American gangs through Fishface, Shredder proves his point by slicing his meatballs and candles, Vizioso swears his allegiance with Shredder. Hun then brings him the chemicals he was looking for. After Stockman-Fly told Shredder they did not have the proper equipment they needed Hun gave Shredder access to the abandoned Auman Chemicals (where the chemicals were obtained from) on the Purple Dragons' turf in extage for being put in charge of the facility. After the Turtles and Casey Jones toss an additive into a chemical vat which causes a chain reaction, he says that they have only delayed his plans and orders his henchmen to clean up the factory and start all over. Donnie later learns that The Foot are working on a mind control formula.
In Clash of the Mutanimals, the planned Mind Control Serum is complete by Baxter Stockman while Saki examines the mentally unstable Karai caged. Rather than use Karai as a weapon, Shredder orders Stockman to place the Brain Worms into the minds of Slash and Dr. Rockwell (previously captured by Tiger Claw at the docks) as test subjects. Shredder later appears after Raphael, who was captured by Rockwell and Slash, is subjected to the same experimentation. Despite Raphael wanting to defeat Shredder permanently, he falls to the injected worm's control. When the other Turtles and remaining Mutanimals arrive in a rescue attempt, Shredder orders the three brainwashed mutants, Stockman, and Tiger Claw to eliminate the guests; Shredder watches over the battle from a throne surrounded by flames. After Rockwell, Slash, and Raphael are freed Shredder decides to take matters into his own hands, combating all eight mutants with relative ease. While battling Leonardo and Raphael, Slash and Leatherhead are able to push a statue down to blindside Shredder before escaping when Tiger Claw and Stockman return with reinforcements. Once freed by the Foot Bots, Shredder bellows in anger for another failure to eliminate his enemies.
In The Deadly Venom, Shredder only appears at the episode's beginning. After Karai is administered the brain worm by Baxter Stockman and easily defeats Rocksteady, he orders his mind controlled "daughter" with a mission: the elimination of the Turtles, Casey Jones, April O'Neil, and Splinter.
In Tale of the Yokai, a young Oroku Saki appears during the Turtles' battle with the Hamato Clan, referring to the deities as yokai, ancient Japanese monsters before Michelangelo throws a smoke bomb to escape. Saki goes to the dojo to explain to Hamato Yuuta of his encounter, only to be dismissed by an arrogant and younger Hamato Yoshi. The two "brothers" then combat one another in sparring; the duel turns intense over the mentioning of Tang Shen, with Saki claiming his friend doesn't love her. Knocking him down, Yoshi offers a hand to his friend only for Saki to bitterly reject the kind gesture. Later at night, Saki shockingly protects Shen and her daughter Miwa when the Turtles foolishly behave which causes Miwa to cry. Oroku reveals to Shen of overhearing an earlier conversation between her and Yoshi of the latter's refusal to move to New York and is willing to fill Yoshi's role, claiming to be a changed man before softly kissing her forehead. The tenderness of Saki is seen by Yoshi; when dueling with Saki again, Yoshi fights angrily, demanding to know of the discussion between his wife and "brother". Despite Yuuta's attempts of calming the two, jealousy and bitterness harms Yoshi and Saki's friendship. Out of a lust for vengeance, Saki offscreen drills several Hamato Clan ninjas of the clan's ignorance. Desiring revenge, he torches a shrine and declares the Foot Clan's rise once more; his first target is none other than his former "brother" Hamato Yoshi. Armed with two claw gauntlets, Saki attacks the couple out of rejection and insanity, refusing to stop his merciless attack on Yoshi from the conflicts he's fought overtime. As shown from Splinter's previous flashbacks earlier in the series, Saki's assault results in the dojo's incineration; when Shen renters the dojo to prevent further harm, Orkou Saki commits an accidental fatal slash, killing Shen. Though he attempts to save Shen's body, a piece of burning debris hits Saki, giving him the face burn as a reminder of the tragic day. He then takes Miwa away where he restarts the Foot Clan under a new moniker: The Shredder.
In Attack of the Mega Shredder!, Shredder is watching as Karai, in her mutated state, is being repeatedly injected with mind-control worms. He shows no remorse in what he's doing, instead apologizing for his actions and how they will have their revenge soon. He then requests that Bebop and Rocksteady double the security as he senses the Turtles will attempt another move against him, threatening them with punishment if they fail again. Though the Turtles make it into the catacombs and are beaten back by Bebop, Rocksteady, Tiger Claw, and the Shredder Elite, Shredder is still furious and threatens to punish all of them if it happens again. In an attempt to make it up to him, Bebop and Rocksteady try to help as they manage to capture Mikey and Leo when they infiltrate Stockman's lab alone, but thanks to the turtle brothers suggesting adding the Shredder Elite to what Bebop and Rocksteady intend to do to them, it results in the three Shredder mutants being fused into the Mega Shredder, an amalgamation of all three that proves to be a difficult enemy to the Turtles. After it has been destroyed by the Turtles, Shredder is furious with Bebop and Rocksteady over their stupid act, and leaves Tiger Claw to punish them for their actions.
In Annihilation Earth, Shredder is surprised to find April and Splinter having infiltrated his lair and wonders why. Splinter requests that they call a truce and unite to stop the Triceratons from destroying the Earth with the Heart of Darkness. When he hesitates as to why he would join forces with his sworn enemy, April tells Shredder that if the Earth is destroyed, he will never see Karai again. Taking this into account, Shredder agrees to the truce between the Hamato and Foot clans, and has his mutant lackeys assist in fighting the Triceratons. However, with the timer on the Heart of Darkness detonator reaching zero, Splinter calls Shredder to help stop it, but instead of saving the Earth, Shredder condemns it to annihilation as he seizes the moment, and murders Splinter in cold blood, finally attaining his vengeance: this resulted in April blasting him back with a psychic blast. When Tiger Claw calls him up on this as they are about to be sucked up by the black hole, Shredder shows no remorse in what he has done, only happy to know that his long-time enemy is finally dead and the clan war between him and Splinter has ended in victory for him. With that, Shredder and his lackeys are among the first victims to be sucked up by the black hole to their doom.
In Beyond the Known Universe, Shredder was shown in the flashback when the earth was getting destroyed. However, after the turtles, Casey Jones and April were saved by Fugitoid, he sent them 6 months back in the past so they can find the three fragments of Heart of Darkness to save Earth. It shows that Karai has not been turned into a snake and Splinter has not been killed yet.
In Trans-Dimensional Turtles, Leonardo envisions Shredder stabbing Splinter while he talks to him in the dojo.
In Earth's Last Stand, Shredder had agreed to save Earth again, however, as the future Turtles made it to the present battle, he was almost going to stab Splinter again and doom the planet. Leo quickly warns Splinter and prevents his death, resulting in Splinter being furious at how Saki would rather have the planet destroyed than let his vendetta go. Splinter and Shredder briefly fight, going back and forth about how meaningless their feud is at this point. In the end, Splinter effortlessly defeats Shredder and leaves him for dead, with Tiger Claw carrying him off while swearing vengeance on the Hamato clan.
In City at War, Karai and her old friend Shiniagami plan to rebuild the foot clan and take down Shredder's criminal operations. At the end of the episode, Tiger Claw talks to Shredder about their failed mission, in their new hideout, revealing that Shredder has actually been left sick and dying since his last encounter with Splinter, with Baxter Stockman pumping mutagen into his body to keep him alive.
In The Insecta Trifecta, Shredder gives a very back handed thank you to Stockman for his efforts, being the only mutant he can truly rely on in his current situation. After Stockman's attempts at creating a mutant insect army for him fails, Shredder reveals that Stockman's plan of putting mutagen in his body worked, popping two Wolverine-esk claws out of his right hand.
In The Super Shredder, though his recovery is doing well, Shredder grows impatient, and orders Stockman to inject the rest of the mutagen into him at once, despite Stockman's pleads that it needs to be stabilized first or the effects could warp Shredder's mind towards insanity. Stockman reluctantly does as ordered, but as Shredder starts to get up, the unstable mutagen kicks in, causing him to thrash around the room, grabbing the Kuro Kabuto and putting it on, before fully mutating into his Super Shredder form, just as Rocksteady enters to see what happened when he heard Shredder scream in pain. Tiger Claw arrives shortly thereafter, and immediately demands to know what happened from Stockman, before Shredder tells them it is time to bait the trap for Splinter, and orders them to fetch Rahzar. After cutting power to the Turtles's lair and his old headquarters where Karai was now stationed, Shredder arrives with Tiger Claw and Rahzar, and confronts Karai. Despite the best efforts of Karai, Shinigami, and their Foot Ninja, Shredder overpowers all of them, before forcing Karai to surrender to him under threat of hunting down Shinigami if she doesn't. Once outside, with Karai his prisoner, Shredder is confronted by the Turtles and April in the Shellraiser, but when they try to charge him, he easily lifts the front of the Shellraiser off the ground, before delivering an ultimatum to them to take to Splinter: If Splinter ever wants to see Miwa again, meet Shredder at the last place where they fought and Shredder beat him. With that, Shredder tosses the Shellraiser across the street, then ignites the leaking fluid from the Shellraiser, engulfing it in flames.
Taking Karai to where he sets up his trap for the Turtles and Splinter, Shredder begins his trap by luring Splinter away from the Turtles with various photographs of his and Splinter's past regarding Tang Shen, Karai, and other moments, setting them ablaze, before finally confronting him when he arrives where Karai is being held hostage. Shredder proves too powerful for Splinter, and Splinter is forced to use a smoke bomb to escape and lure Shredder to where Splinter fought The Rat King. Though Splinter has the advantage at first, Shredder soon has him right where he wants him, but before Shredder can finish the job, his arm begins to act crazily, a side-effect of the unstable mutagen that Stockman had warned of. Despite that, Shredder soon manages to crush one of Splinter's feet under his own and prepares to kill him, but a distraction from the Turtles, April, and Karai, gives Splinter the chance to toss a kunai at where he had set up several explosives, detonating them and causing the segment of broken bridge Shredder and he were on to crumble and collapse. Shredder tries to jump to safety to go after the Turtles, April, and Karai, but Splinter manages to grab him, and both of them plunge into the abyss, presumably to their deaths, leaving Bebop, Rocksteady, and an army of Chrome Dome Elite Foot-bots to deal with the Turtles, April, and Karai now that they lost their Sensei and father. Whether or not he survived is left for debate.
In Darkest Plight, Shredder survives the fall Splinter pulled him into by landing on an I-beam, while Splinter falls deeper into the chasm, but cannot pull himself back up to the top of the under-city due to the damage his left hand suffered from the unstable mutagen. Tiger Claw helps him back up, but is horrified when he sees Shredder's hand, and pleads with him to avoid taking any more mutagen as it could be deadly. However, Shredder ignores this, and orders that Zeck and Steranko remain behind to ensure Splinter's dead while he and Tiger Claw return to his hideout to recover before resuming the hunt for the Turtles, April, and Karai.
Once recovered, Shredder and Tiger Claw return to hunt them down, and upon finding Leo, Karai, and April, Shredder orders Tiger Claw to go after the girls while he deals with Leo. They attempt to draw Shredder and Tiger Claw to the surface, but Shredder soon finds Leo lying in a pile of garbage bags, grabs him, and flings him out into the street, in full view of several innocent civilians who run for their lives upon seeing Super Shredder. Grabbing Leo, Shredder starts to squeeze him to death between his hands, before being interrupted by April and Karai. At one point, April seems to have the advantage over Shredder thanks to her psychic powers, but when Shredder is slammed into a building by a fuel tanker semi-truck, he throws it towards Karai, only for April to catch it in her psychic grip, and after having her eyes glow blue and smile malevolently thanks to her Sol Star crystal aiding her, April flings it back at Shredder, before collapsing in fatigue. Shredder prepares to finish off Leonardo, but Karai intervenes, pleading for him to do something good in his life instead of waste it on his vengeance. Moved by that, Shredder attempts to apologize to Karai for his behavior, but Karai reveals she was simply luring Shredder in as she punches him right in his exposed mutated heart, weakening him so his hands begin to fall apart again from lack of stable mutagen. Before Karai can finish him, Tiger Claw arrives to evacuate him back to their hideout, and Karai does not pursue as she helps April get Leo home for medical attention.
Once back at his hideout, Shredder demands a larger dose of the mutagen from Stockman, but Tiger Claw intervenes, saying it is too dangerous, only to be overpowered as Shredder forces Stockman to administer the dosage. Tiger Claw can only watch in shock, disbelief, and fear, as Shredder lets out an enraged scream as the mutagen takes effect.
In Requiem, Super Shredder checks on Stockman, who has finally perfected the mutagen and injects a dose of the perfected super mutagen into Shredder, causing him to spawn more blades on his body, and feel his body feeling stronger and more stable now. Deciding to test it out on some Elite Foot-bots and a hologram of Karai, Shredder shows no remorse as he cuts the hologram Karai down, and prepares to face Karai and Splinter once and for all when word arrives that Karai and Shinigami are hiding out at the Mighty Mutanimals' hideout in the Bronx. Super Shredder lays siege to the place and sets it on fire, overpowering all the Mutanimals before confronting Karai, taunting her at how she'll be meeting the same fate as her mother with dying in an inferno. When Karai tries to run Shredder's mutated heart through with her tanto blade, the stabilized mutagen causes her blade to break, and Shredder throws her to the ground to be buried under rubble and left to perish in the fire.
Afterwards, he waits for Splinter at the Wolf Hotel, the very same place he first fought the Turtles before his mutation. He easily overpowers and knocks out Slash, badly wounds Raphael, wounds April on her arm, and throws Casey off the building, only for him to survive thanks to his grapple hook, before facing Splinter. At one point, it looks like Shredder loses as Splinter trips him up and flings him off the roof, but Shredder recovers and ambushes Splinter, running him through the chest with his blades and finally killing him, attaining his vengeance. However, Super Shredder only enjoys his victory for a short while before a furious April calmly blasts him off the roof with her psychic powers, sending him crashing into the back of a garbage truck, where Casey activates the crusher, hoping to end Shredder's life and avenge Splinter immediately. However, after the Turtles leave in the Shellraiser with Splinter's body, Super Shredder punches his way out of the garbage truck through the roof.
In Owari, after making it to the hideout, fighting much of the Foot Clan's forces including Foot-bots, Fishface, Stockman Bebop and Rocksteady, and Tiger Claw, the Turtles, April, and Casey, are confronted by the Super Shredder, who throws Molotov cocktails at them from the from the roof of the mansion. Casey and April are cut off as the flames spread, leaving the Turtles to go after Super Shredder alone.
Super Shredder expresses how he believes that the Turtles would leave the city after Splinter was defeated as they in the The Invasion, Part 2, but the Turtles state that the would not run that everything would end tonight. The Super Shredder tosses off his cape and they five engage in battle.
The Turtles each attack with the best of their abilities, but the Super Shredder proves to be stronger and overwhelms them while mocking their tactics. The fight becomes more intense as the Turtles pin Super Shredder down and even dose him with Donatello's vial of retro-mutagen, but Super Shredder proves to be invulnerable.
Back on his feet, Super Shredder attacks, throwing Donatello, Michelangelo, and Raphael one by one off the roof until he and Leonardo are the only ones left. In the midst of the duel Leo furiously reminds Super Shredder that he killed Splinter, his brother and best friend, also questioning how could he do it. As Super Shredder beats Leo, he replies that Splinter was cursed from the beginning to become a lonesome rat, that he refused to fight his destiny. However, Leonard snaps at Super Shredder, referring to him as a monster, a demon, and asks if it was his destiny to be one. For brief moment of humanity, Super Shredder considers Leonardo's word and hesitates to kill him. Leonardo takes advantage and attempts to strikes, but Super Shredder overpowers and disarms him and tosses him aside. Super Shredder walks over to the battered Leonardo with blades at the ready and prepares to finish him off. However, Leonardo sees Splinter's spirit once more and is told to fear nothing. Leonard rises and fend off Super Shredder with a powerful assault of blows before retrieving his katana. Now armed, both and Leonardo and Super Shredder charge in the air at each other and Leo strikes Super Shredder with fatal blow before the two vanish within the flames, killing Shredder once and for all.
In the episode "Scroll of the Demodragon", Tiger Claw releases the Demodragon Kavaxas, intending to have him revive Shredder.
In "The Forgotten Swordsman", Tiger Claw and the rest of his followers collect Shredder's remains so Kavaxas can revive him, however, in order for the process to be complete, Kavaxas states that he needs the Kuro Kabuto, which contains Shredder's mental energy, and his heart, which contains his soul. Later, upon learning of Tiger Claw and Kavaxas' plans, the Turtles, April and Casey Jones decide that it is best to help Karai and Shinigami retake the Foot Clan and Kuro Kabuto from Hattori Tatsu. After the Turtles, while fighting Tatsu, discover that he is blind, he explains that he was born blind, yet had an acute sense of hearing, and, while others mocked him, Shredder saw his skills as an asset and let him join the Foot Clan.
In "Heart of Evil", the Turtles, April and Karai fight with Tiger Claw and his forces over Shredder's heart, which is in the possession of Don Vizioso and his gang. Ultimately, the Turtles fail to retrieve the heart, allowing Kavaxas to finally revive Shredder, albeit in a more zombie-esque state.
In "End Times", Shredder is confused and disoriented after his revival, stating that he had been dead for millennia when he had really only been so for a few months. However, after Tiger Claw informs him of what had happened, Shredder decides that it is time to take revenge on the Turtles. After the Turtles enter Tiger Claw's lair, they end up fighting Zombie Shredder, who proves to be too much for them (due to now having telekinetic and regenerative powers), until Michelangelo steals the Seal of the Ancients and forces Kavaxas to battle Shredder for them. After the Turtles escape, Shredder immediately tells Tiger Claw that Kavaxas will be his new second-in-command.
Later, Tiger Claw begins to suspect that Shredder is under Kavaxas' influence, a thought that is only amplified when Shredder demands that he hand over the Seal of the Ancients to him. When Tiger Claw refuses, Shredder and Kavaxas unleash a feral Rahzar on him, and, during their struggle, Shredder stomps on the Seal, splitting it into three pieces. Kavaxas then laughs and states that his actions; killing an evil warrior (Tatsu), reviving an evil warrior (Shredder) and destroying the Seal had actually been part of a ritual that would allow him to unleash the spirits of the underworld on the Earth and wipe out humanity. When Yiger Claw demands his master to help him fight Kavaxas, Shredder states that Kavaxas is in fact his master now.
As Leonardo, Karai, Michelangelo and Leatherhead arrive to fight Kavaxas, Shredder fights with Leonardo and Karai and is seemingly defeated when the latter knocks him off the edge. After Michelangelo fixes the Seal and forces Kavaxas to undo everything and banish himself, Kavaxas tries to resist entering his portal, and Shredder, angry at being used and dissatisfied with his current body and new life, jumps on top of him and forces him through, stating that they do not belong in the mortal realm.
- Hamato Yoshi/Splinter - Oroku and Hamato were raised in Japan as adoptive brothers and very good friends, and the two learned, exercised and became Masters in the art of Ninjitsu. However, their companionship suffered a great strain when they both fell in love with the very same woman, Tang Shen. They constantly competed for her attention, but she chose Hamato in the very end. Jealous, Oroku began harassing Hamato, insulting him and purposely trying to get him angry. This eventually culminated when Oroku learned of his true heritage and restored his birth clan as "the Shredder". Breaking into Hamato's own house and challenging him to a mortal duel, both men engaged in battle, and the house soon caught fire in the process (due to the fact that some burning candles were left laying around at the time), killing Tang Shen and horridly burning the Shredder's face. The latter found Miwa and secretly took her in, raising her as his own daughter and telling her many lies about what Hamato "did". Sixteen years later, the Shredder discovers that Splinter is hiding out in New York City, and he leaves Japan (along with his deployed Foot Ninja) to finish him off. The two finally meet again in "Booyaka-Showdown, Part 2" and duel with each other in The Foot Headquarters. The Shredder soon reveals to Splinter that his daughter is indeed alive, and he attempts to have her kill Splinter when she shows up. With this revelation, it is likely that Splinter despises The Shredder even more than he formerly did. In "Wormquake", the two were excepted to a duel in Shredder's Hideout when Splinter was recaptured, only to be rescued by the Turtles.
- The Turtles - Since they are affiliated with Splinter (as his disciples), Shredder views the Turtles as enemies, and he orders his henchmen to find and kill them throughout the entire series. However, out of the two times that The Shredder has encountered them, he's let them live only for the purpose of interrogating them (which hasn't yet happened).
- April O'Neil - Shredder learned from his Kraang hostage that April is not only a friend of the Turtles, but also the missing link to the Kraang's invasion plan that the Turtles are gaurding from them. So with the Kraang's help, he uses April as bait to lure Splinter out of hiding. Due to this, it is quite probable that April dislikes him greatly.
- Casey Jones - Shredder almost caught Casey spying on the meeting at Vizioso's restaurant but excepted the boy's lie that he was a bus-boy and kicked him out. Later, at the Auman chemicals factory, Casey stops Shredder in his vigilante gear and attempts to fight him, but Shredder is unstoppable for Casey and unmasks him as the same boy from the restaurant.
- Hamato Miwa/Karai - Shredder kidnapped Splinter's baby daughter, Miwa, after the events of his and Hamato Yoshi's final battle, named her Karai, and raised her as his own child. However, it was uncertain that Saki truly loved Karai like she does him. In Season 2, after she finds out that Saki is not her true father, she betrays him and he has her locked away. In "Vengeance is Mine," Shredder did not want Tiger Claw to kill Karai when she got out. When Shredder wanted Karai to understand what he had to do, Karai told Shredder that he is not her father. After the Turtles freed Karai, Shredder states to Tiger Claw that Karai will want to have her revenge on him. When Karai arrives to get her revenge on Shredder, she ends up overwhelmed by Shredder who manages to defeat her. Shredder then plans to use Karai as bait so that he can have the Turtles fall into the mutagen vat filled with snake DNA that Stockman had placed in there. During Shredder's fight with Splinter, Shredder tried to stop Leonardo from freeing Karai only for her to fall into the mutagen vat and emerge as a snake-like mutant much to the dismay of Shredder and Splinter. Shredder blamed Splinter for Karai's mutation as the resulting battle ends up destroying Stockman's lab. He escapes after vowing to avenge Karai. This event reveals that despite Shredder's cold attitude and lack of empathy to Karai, he truly saw her as his daughter and loved her dearly. He also continues to refer to her as "his" daughter because he still sees her as his own because he raised and cared for her and desperately searches for her so the Kraang can mutate her back to normal.
- Slash - Shredder and Slash don't interact much except when the dishonorable ninja used his Mind Control Worms on him to atack Splinter and abduct Raph, but Slash breaks free of from Shredder's control with the hel of the Turtles and the other Mutanimals, then drop a huge statue on the crimelord.
- Leatherhead - Shredder's attempts to kill Splinter during the Kraang invasion was interfered with by Leatherhead when he bites Shredder's stomach and threw him into the building. As Leatherhead attempts to free Splinter, Shredder attacks him in return and kicks him down into the river.
- Chris Bradford/Dogpound/Rahzar - Shredder trained Bradford in his own image as the Foot's top lieutenant and second best fighter, maintaining his rank and respect to the entire clan.
- Xever Montes/Fishface - Shredder freed Montes from prison after Montes was caught burglarizing his property by the police, mainly because he found his burglarizing skills very useful to his clan, as well as the fact that Montes likes having a job where he gets to crack skulls almost everyday.
- Baxter Stockman/Stockman-Fly - Shredder spared Stockman after Stockman's M.O.U.S.E.R.S's interfered with his feud against the Turtles, mainly because he found his talented inventing skills very useful to his clan, which led to several improvements, such as making Fishface a pair of robotic legs, thus making the latter a more powerful combatant. Shredder, however, for the most part, cares little for Stockman and he probably chose to dislike him even more after the scientist trapped Dogpound and Fishface in the "Maze of Doom". Stockman still buys back Shredder's favor by creating a formidable or even decent mutant army for him.
- Tiger Claw - Shredder found Tiger Claw in Japan and found his bounty hunting skills very useful, thus he made the feline fatality his second-in-command. Though Tiger Claw is unimpressed with the Foot Clan, he accepts the job regardless. Even after Tiger Claw returned from the stomach of the Kraathatrogon, he was reinstated as the second-in-command, showing how Shredder respects his ally's skills.
- Ivan Steranko/Rocksteady - Shredder and Steranko have been business partners in the mafia, but Shredder doesn't always trust him that much. This distrust escalated after Shredder found out that he sent Zeck to steal the Kuro Kabuto and was hunting Karai, and had Steranko work for him as payment for his treachery.
- Anton Zeck/Bebop - Shredder was almost robbed by Zeck of the Kuro Kabuto, which the Turtles return to him in exchange for Karai. Upon finding out that Zeck was employed by Steranko, Shredder proceeds to have the thief punished for stealing his helmet and hunting Karai without consent by employing him and Steranko into his service.
- Don Visioso - Shredder and Vizioso have been business partners in the mafia like he was with Steranko, and during Shredder's meeting with the food critic at his restaurant, he announces that the Kraang have given him the opportunity to gain control over much of the crime groups in the city. Thus, he asks Vizioso to join in by sharing control of his mob to him, and after being proven a point, Visiozo complies.
- Purple Dragons - a street gang and occasional allies.
- Hun - Shredder considers Hun his only pupil in the Purple Dragons, and he helps Shredder retrieve a chemical from the Aumen Chemicals Factory for his mind control serum.
- The Kraang - An alliance made only to get closer to Hamato Yoshi, but his true intentions were to use their technology and mutagen for himself when the time is right to betray them.
- Tang Shen - A woman that both Oroku Saki and Hamato Yoshi fell in love with. She chose Yoshi over Saki, however, and in a fit of jealousy and rage, he attacked Yoshi one night and killed Tang Shen in the process when he missed a swing meant for Yoshi and killed her instead.

- In Splinter's flashbacks, Shredder is seen wielding a pair of "Tekkō-kagi" (lit. "back of the hand hooks"). In the present, he is seen with custom-made Tekko-kagi claw weapons: They have extendable blades and are razor sharp. They have also been shown to be strong enough to cut through metal shipping containers.
- The Shredder's real given name "Saki" is (usually) a female Japanese name that means "blossom" and "hope".
- He owns an Akita Inu named Hachiko. Hachiko contributed to Dogpound's mutation by biting him before the mutagen spilled on him.
- In the episode "Tale Of The Yokai", the Turtles go back in time in Japan and will meet him before 16 years later.
- He is one of the darkest and most villainous Nickelodeon villains along with: Dark Danny, Dag, Gus, Unalaq and Ozai.
- It is unknown why Shredder is sick and dying in the recent episodes. It could be because, A: Since Splinter is a giant rat who lives in the sewers, Shredder could have been infected by one of the blows Splinter landed on him, B: His helmet was removed for a long period of time, and therefore not covering the areas of his face that had no skin on them, making it easier for him to be infected, or C: The jabs Splinter made at his pressure points on his chest and stomach areas could have stopped his organs from working properly.
- Ironically, Shredder has become what he hates the most: an mutant.
- Shredder is making an appearance in the most popular series on Youtube DEATH BATTLE to face off Silver Samurai from Marvel's X-Men.
