But more importantly she states that she wants to go after Luffy for what he has done in her territory.

She then told him that when Luffy makes his way to Wano Country to not kill him as she wants to be the one to kill him, so that she can save her own reputation. Kaido still refused and tells her that Luffy is his prey. Big Mom reminds Kaido of his debts to her, but the latter was upset and threatened to kill her if she came to Wano Country.

As a result, the ship falls down the waterfall and Big Mom falls into the ocean.

She destroys a few gates and manages to make it into the prison where Luffy, Queen, the Beasts Pirates, and the prisoners are at. When people calls her Big Mom, she wonders what that is. She tells O-Tama that she smells O-Shirukos and that she should come inside the prison with her. She tells Queen and everyone in the prison that she was told that there were O-Shirukos at the prison and that she wants to eat it. Agitated at her response, Queen turns into his Brachiosaurus form and tells her that all the O-Shirukos is his to eat. Big Mom jumps up and slams Queen's head into the ground demanding the O-Shirukos.
She grabs Queen and begins spinning him around demanding that he gives her the O-Shirukos and then throws him onto the wall on the other side of room. Big Mom grabs the container that had the O-Shirukos and is happily awaiting to eat the O-Shirukos inside. When she opens the container and sees that it is empty, her expression turn from joy to sadness. As the Beasts Pirates try to figure out how to deal with a potentially angry Big Mom, Luffy accidentally blurts out that he ate the O-Shirukos and that it was delicious. Big Mom attacks Luffy and yells at him. She tells him that she wanted to share the O-Shirukos with the villagers she met earlier since they were kind to her. Big Mom destroys the sparring ring that Luffy and Hyogoro was in. She punches both Luffy and Hyogoro and sends them flying into a wall. Big Mom goes chase Luffy across the prison attempting to kill him out of rage for eating all the O-Shirukos. As she gets back to the same spot where she began chasing Luffy, Queen in his brachosaurus form, headbutts Big Mom causing her to regain her memories. Big Mom remembers that she fell into the water and that she went to one of the villages in Wano. Her aura changes dramatically which shocked Queen and the Beasts Pirates. She turned around and recognized Queen before falling asleep. While she remained asleep, Queen and Beasts Pirates sedated Big Mom with 100 anesthetic shots and wrapped her in 100 pure seastone chains. They immediately took her from the prison, placed her on a ship, and prepared to send her to Onigashima where Kaido resides.
In Onigashima, Big Mom is still chained with seastone chains. She is fed plenty of food by the Beasts Pirates. Big Mom sits in front of King, Queen, and Jack. As Queen blames King for enabling Big Mom to enter the country, Big Mom tells King that she is willing to forgive King for what he did. She says that King is a part of one of three races that she does not have in her country and says that he is a part of a race of people that is allegedly wiped out from history. Big Mom offered for him to join her side but he refused. She then demand the Beasts Pirates to remove the chains from her. Kaido appears and orders his men to remove the chains. With the chains removed, Kaido reminds Big Mom that he will kill her since she entered Wano Country. Big Mom gets out Napolean and prepares to fight him as they both clash.

Big Mom eats her O-shirukos and Kaido drinks his alcohol. The two are excited about the banquet coming up. Queen wonders why they are so happy after trying to kill one another. They revealed that they are now allies and that their pirate teams are going to come together. They say that they are going to go into an alliance to take over the world and after they succeed they will kill each other afterwards.
The evening of the Fire Festival, Big Mom is seen changing into a kimono and getting make-up by others. She talks to her children and the Big Mom Pirates when they were trying to enter the country. When she hears noise outside of the building she is in, she opens the door to see what the noise is and makes eye contact with Chopper as he is in the Brachio Tank V. When she realizes Chopper is a part of the Straw Hat Pirates, Big Mom chased after the tank yelling that she wants them to hand Luffy over to her. She managed to catch up the ship and attack it hurting both Chopper and Usopp. However after attacking them, Big Mom turned her attention to Nami, Shinobu, Carrot and Zeus. Prometheus calls out to get Big Mom's attention in hopes of getting her to get to where Nami, Zeus, and the others are at. At the same time, Big Mom uses her powers to bring to life inanimate objects while pursuing her enemies. She manages to reclaim Zeus and capture Nami and Carrot. Big Mom soon made an appearance in front of the Beasts Pirates where Kaido announces his new plan, the "New Onigashima Project". Kaido states the plan would involve allying the Big Mom Pirates, finding the ancient weapons and the one piece, and bringing war and terror to the entire world. Kaido then states that he would turn Wano's citizens into slaves to help manufacture weapons for his army and would completely take over the entire country to turn into a pirate paradise. When Orochi objected to Kaido's idea of taking over the Flower Capital, Kaido beheads him to the horror of his own and the Beasts Pirates. Big Mom laughs in amusement as Kaido exclaims his intentions of making his daughter, Yamato, the new shogun of Wano.
After the announcement of the "New Onigashima Project", Big Mom holds back Nami and Carrot with her homies. Big Mom spectates along with the Beasts Pirates Kaido speaking to Momonosuke and his attempt to execute him after the latter told him that he is who he is and that he intends to become the shogun of Wano. A big explosion caught Big Mom and the Beasts Pirates's attention. Big Mom and the Beasts Pirates also watch the Nine Red Scabbards attack Kaido on stage. As Kaido falls to the ground from the attack, Big Mom was excited about the festival and jokingly wonders out loud if Kaido died. When Big Mom sees Luffy, she approaches him. She tells him that she arrived at Wano with the intention of killing him. She asks him why he came to Wano and then says that if he is here to take down Kaido then it is silly. Luffy tells Big Mom that he is here to take her down along with Kaido, Orochi, and all of their subordinates. Big Mom laughs saying that he cannot take her or her allies down with a small number of people.
Big Mom overhears the battle between the Scabbards, Minks, and Kaido and the Beasts Pirates at the top of the skull dome. She turns her attention back to Luffy and says that he always ruins parties and gatherings for her. Big Mom attempts to kill him with a powerful sword attack that had a shockwave that went out to the sea. Spectators comment on her strength and members of Luffy's alliance say she was like a second Kaido in term of powers. Big Mom attempts to get Zeus back from Nami and manages to grab it from her. As Big Mom is about to attack again, she is caught off guard by an attack from Franky and Brook. Brook cuts Zeus in half and Franky rams his motorcycle into Big Mom's face sending her falling onto the floor. She stands up a few moments later without sustaining any injuries. She notices Brook and Franky and says that the Straw Hats have interesting creatures in their crew. Franky introduces himself to her and prepares to charge a powerful laser beam to attack her. Big Mom is concerned about the attack. When the numbers barged into the room, Big Mom recognized them as failed ancient giants that were from Punk Hazard. As Franky turned his attention to one of the numbers and attacks them for having the Brachio Tank V, which had Chopper and Usopp, in its possession, Big Mom attempts to attack Franky for using the powerful attack on one of the numbers. As she was about to attack Franky, Jinbe grabs Big Mom's arm and throws her onto Robin's hands that she extended from the ground. Big Mom tells Jinbe that she will kill him for betraying her crew before Robin uses her hands to roll Big Mom out of the room.
After being removed out of the skull dome, Big Mom meets with Perospero and Marco. Marco and Perospero tries to persuade her to leave Kaido and to join the opposition against him. Big Mom refuses and asks Perospero if her children did not believe in her. Big Mom also remarks on the remainder of Whitebeard Pirates. Marco and the Big Mom begins to fight. As she fights Marco, she notices that Perospero is attacked by Carrot and Wanda. As the battle continues, Big Mom leaves Marco and gets onto the Zeus to fly to the top of the skull dome to meet Kaido.
Big Mom arrives and speaks to Kaido who finished defeating the Nine Red Scabbards. Big Mom wonders what Kaido intends to do with the flying Onigashima capital and notes that if he drops it on the Flower capital that a lot of people are going to die. Kaido says that the capital would look better. Big Mom tells Kaido to spare Robin's life since they would need her to read the poneglyphs. Kaido asks her about her daughter, Pudding, to which she brushes off by saying her powers has not developed yet. Kaido asks if it is too early for her to be revealing her true colors and Big Mom says to not underestimate her as she sees him as her little brother. She reminds Kaido that she gave him the mythical fish-fish fruit and that he owes her a life-time debt. Kaido says that they can settle their differences after getting the One Piece.
Big Mom and Kaido watch as the Supernovas, Eustass Kid, Killer, Roronoa Zoro, and Trafalgar Law gather in front of them. Big Mom gets excited when Luffy approaches them and says that she wants his head. Big Mom tells Luffy that he neeeds to apologize for destroying her castle while Kaido tells Luffy to repeat what he told him about being Pirate King. Luffy ignores both of them as he checks on a battered Kinemon. When Kaido presses on to Luffy to repeat what he says, Luffy catches him off guard with a Gear Third attack shocking Big Mom. Big Mom asks Kaido how he was able to allow Luffy to land an attack on him before Luffy tells both of them that he intends to be the Pirate King. Big Mom yells at Luffy and asks him if he knows what it means to be the Pirate King. After Kaido stands up and attacks Luffy, Big Mom attempts to burn Luffy with Prometheus until Zoro cuts Prometheus in half. As Promotheus recovers, Big Mom orders it to burn Luffy, Law, and Kid by shooting fireballs at them. As the trio were distracted, they take a direct hit from Big Mom's attack. Big Mom joins with Kaido as they tell the Supernova captains that they will kill them, take their crew, and take their poneglyph rubbings. Kaido tells them that whoever wins this fight is closer to being the Pirate King.
As the battle continues, Big Mom continues to attack the Supernovas by using Zeus and Prometheus to stir up a lightning storm. As the Supernovas are struck by Lightning, Big Mom notices that Luffy is unaffected by the lightning. She asked Luffy how he's resilient to the lightning, he tells her because he is made of rubber before nearly attacking her. However, Kaido intercepts Luffy's attack. Big Mom is soon attacked by Law who used his countershock attack on her. Big Mom looks on in surprise when Zoro manages to cut Kaido with his sword attack. As Kaido transforms into his hybrid form, Big Mom joins right next to him as they continue their battle against the Supernova.
Big Mom and Kaido combine their abilities to injure the Worst Generation. However, Law imprisons Zeus inside of Eustass Kid's metallic box and Zoro slice up Prometheus causing Big Mom to fall onto the floor. Big Mom insults them for their efforts saying that they cannot stop her. Big Mom punches Kid in the face, but Kid repels her with his devil fruit ability and Law throws a boulder at her. Big Mom asks what is the point of attacking her with a boulder until she realize that she was falling off Onigashima into the ocean below. She asks Zeus for help but Law states that Zeus will not come to her aid and that it is time for her drop out of the fight.
Big Mom was saved by Prometheus and made her way back onto Onigashima to go on a rampage against Luffy's allies, but not before Prometheus convinced her to create a new special Homie to replace Zeus. She wanted to find Law and Kid and kill both of them out of revenge for nearly killing her. She encountered Usopp, Nami, and Tama. Big Mom became protective of Tama with her mother mode and helped to defeat Ulti as she attempted to kill Tama. Big Mom introduced her new special thundercloud Homie, Hera, to assist her in battle. When Zeus caught up, Big Mom revealed that she no longer needed him and fed him to Hera. However, when Tama chooses to stay with Nami and Usopp after witnessing this betrayal, Big Mom was mad at her and wanted to attack Tama for leaving her.
Big Mom manages to find Law and Kid during the battles in Onighashima. She engaged in a battle against the two younger pirates where she had an upper hand against them. However, during the battle, Law and Kid were also critically injuring her and overwhelming her with their powers. At one point she was buried under a pile of steel beams when Law manages to hurt her with his kroom anesthesia and Kid used Punk Clash to attract all the beams to her. Big Mom got up from the attack and was enraged and grew in size by taking a bunch of bystander's life span with her soul pocus move. She continues to fight against the duo.
