Villain Overview
I was not born a Pokémon, I was created! And my creators have used and betrayed me! So... I stand alone!
~ Mewtwo to Giovanni.
Humans cannot be trusted. I've told you this. It seems you forgotten that, as well.
~ Mewtwo to Detective Pikachu.

Mewtwo is a recurring character and occasional antagonist in the Pokémon franchise. He is a psychic genetic Pokémon cloned from Mew, the Legendary Pokémon ancestor of all Pokémon. Interestingly, Nintendo (for a time) considered Mewtwo the secondary antagonist of the franchise, behind Giovanni. Mewtwo can be considered evil, but more misunderstood because of the way it was created. Mewtwo later redeemed and helps the main cast.

In the anime, he is voiced by Philip Bartlett, and later Dan Green. In the Super Smash Bros. franchise, he is voiced by Masachika Ichimura (Melee) and Keiji Fujiwara (Wii U/3DS). In Detective Pikachu, he is voiced by Chris Smith.

In the Games


In the first generation Pokémon games and their remakes (Red, Blue, Yellow, FireRed, and LeafGreen) along with HeartGold and SoulSilver, Mewtwo is only encountered in Cerulean Cave, with no real storyline significance and can be battled after beating the game. It is seen at level 70.

In X & Y, Mewtwo is found at level 70 in the Unknown Dungeon after beating the game. It is suggested that the scientists of Team Rocket created Mewtwo in the Pokémon Mansion on Cinnabar Island and that Mewtwo destroyed the Pokémon Mansion in its wake as it escaped its human captors and creators.

In Ultra Sun and Ultra Moon, Mewtwo is one of the many legendary Pokémon to encounter while warping through Ultra Space, found in a green wormhole. Unlike the other games, it is only at level 60.

In "Episode RR", during the final battle with Giovanni in Team Rainbow Rocket's Castle, he uses a Mewtwo that he can Mega Evolve into Mega Mewtwo X (in Ultra Sun) or Mega Mewtwo Y (in Ultra Moon). It is unknown how Giovanni acquired his Mewtwo, although it can be assumed he did so through his use of Ultra Wormholes.

Mystery Dungeon

Mewtwo also has a role in some of the spin-offs. It appears as an antagonist in Pokémon Mystery Dungeon - Red/Blue Rescue Team, it is at the end of a 99 floor dungeon called Western Cave. It attacks and defeats Blastoise and Charizard when they attempt to face it and can be fought as a boss after Ho-oh has been recruited. It is defeated by the rescue team and joins them.

Pokémon Ranger: Guardian Signs

Mewtwo plays a bigger role in Pokémon Ranger: Guardian Signs, where it is the main Pokémon used by the main antagonist, Dr. Edward. It is controlled by the use of the Golden Armor. After being defeated the first time, Purple Eyes enhances and controls Mewtwo and uses it itself. After its defeat it banishes Purple Eyes in anger before leaving.

Pokkén Tournament

Mewtwo, referred to as Shadow Mewtwo, appears in the game as the final boss of the story mode. Shadow Mewtwo appears as a black colored Mewtwo with an orange stone impaled through its left shoulder. Originally, Shadow Mewtwo was a regular Mewtwo that befriended a young girl named Anne.

One day, Anne was under attack by the energy released from a Shadow Synatry Stone, which Mewtwo sacrificed itself to save her and was corrupted by the stone. Years later, the Shadow Synatry Stone has fully corrupted Mewtwo and feeds off of its energy released as Shadow Mewtwo defeats more Pokémon in battle. Shadow Mewtwo can also Mega Evolve into Mega Shadow Mewtwo X.

Eventually, the player and his Pokémon fight and defeat Shadow Mewtwo, and Anne uses her brooch harnessing energy from regular Synatry Stones to extract the shadowy stone from Mewtwo, returning it to its original senses. Anne says her farewell to the player and Mewtwo and returns to her people with the purified Shadow Synergy Stone, and Mewtwo becomes a playable character. After the Chroma League is beaten, Shadow Mewtwo becomes a playable character.

Detective Pikachu

Mewtwo appears as an anti-villain in Detective Pikachu. He is first seen during the conclusion of Chapter 3, "PCL", levitating above Tim Goodman and Pikachu as they are wondering where Tim's father Harry could be. In Chapter 4, "Cappucci Island", Tim and Pikachu learn from Dr. Waals that R, a chemical that causes any Pokémon that consumes it to become violent and go berserk, was originally intended to be a miracle drug derived from the cells of Mew. However, Mewtwo's cells were accidentally used instead, and as a result of Mewtwo's Bezerker Gene, the aforementioned effects would occur. In Chapter 5, "Fine Park", Mewtwo again watches over Tim and Pikachu, this time as they leave the park, commenting that, while Pikachu has amnesia, he is still fulfilling the promise he made to him.

In Chapter 7, "Ryme Wharf", Pikachu has another dream about his life before the accident, and sees Mewtwo right before he wakes up. Pikachu then recalls that he had made a promise to Mewtwo, but can't remember what it was. At the end of Chapter 8, "Where R Goes", Mewtwo and Pikachu converse, Pikachu having finally remembered that he promised to retrieve Mewtwo's cells and destroy everything related to R. With Keith Norman's arrest, Pikachu believes the threat of R to be over and that Mewtwo can hold up his end of the bargain, but he states that he can still feel his cells out in the world and that they must be destroyed by his own hands, claiming humans cannot be trusted. Pikachu remarks on how Mewtwo is "the tedious type", and Mewtwo, deciding to simplify things, threatens to destroy everything related to his cells with a Shadow Ball if Pikachu cannot retrieve them. Pikachu calms him down, and Mewtwo informs him that he had done the same in the past, which is why he was entrusted to find his cells. Mewtwo then states that he now realizes there are humans who are dependable, looking in the direction of Tim Goodman and Emilia Christie. Pikachu tells Mewtwo to leave things to him, and the latter subsequently leaves.

In Chapter 9, "Pokémon Carnival", after Roger Clifford is arrested, Pikachu hands the last of the cells over to Mewtwo. Mewtwo asks Pikachu if he has made a choice yet (although to what is not shown), and Pikachu replies that he has, resulting in him falling asleep. Tim sees this and encounters Mewtwo, who tells him that his father is still alive, and he will be found if Tim does not give up searching, before levitating away. 

Smash Bros. franchise

Super Smash Bros.

Mewtwo was originally to be included in Super Smash Bros. as one of three villainous characters (the others being Bowser and King Dedede). However, due to console limitations, he and the other villains were cut from the game.

Super Smash Bros. Melee

SSBM Event 51

Mewtwo as part of Event 51.

Mewtwo is also among the cast of Super Smash Bros. Melee, and considering its role in the last event match of the game, where the player faces a tag team of three villains (along with Giga Bowser and Ganondorf), it is considered a villain by the game.

Super Smash Bros. Brawl

Despite not being a clone like the other cut characters, Mewtwo did not return to Brawl as a playable fighter. It only appears in the game as a trophy. Many fans believe it was replaced by Lucario similar to how others believe that Roy of Fire Emblem was replaced by Ike. However, by looking inside the disc's data, one can discover files for Mewtwo, indicating it was intended to also be playable in Brawl.

Super Smash Bros. for Nintendo 3DS/Wii U

Wii U】Mewtwo Strikes Back!

In the anime

Mewtwo Strikes Back

See full page for this: Mewtwo (anime)

Mewtwo serves as the titular main antagonist of the film.

Mewtwo was created by Team Rocket by cloning DNA from a Mew fossil. It was Team Rocket's intention to create the most powerful Pokémon. However, Mewtwo was angered by the team as it heard that it was to be controlled by them, and that it may not be part of God's creation (Japanese version), and in its fury, destroyed the lab where it was created, and killed all the scientists with its intense psychic powers. It then allied himself with Giovanni under the promise of learning to control its powers, although it later rebelled from Giovanni after learning that Giovanni's claim of partnership had been a lie, and it had already been sickened by Team Rocket's actions towards Pokémon. Believing humans as oppressors of Pokémon, it vowed to exterminate humans and all Pokémon that sided with them, believing it to be its "purpose". It also wishes to exterminate Mew, as it believed itself was vastly superior to its genetic counterpart. It eventually saw the errors of its ways shortly after Ash Ketchum sacrificed himself to stop their fighting, and removed their memories to avoid being tracked down.

Its backstory was expanded upon, where it interacted with several clones of a Charmander, Squirtle, Bulbasaur, as well as a clone of Amber, the daughter of Dr. Fuji. It was eventually distraught over its friends, especially Amber's premature death, which also resulted in the scientists injecting it with a serum that removed any memory of her, which is strongly implied to have impacted its behavior in the film.

Mewtwo Returns

Mewtwo serves as an anti-hero here. It was hiding in Kena Mountain with the other clones. It saved a bus with passengers, but it feels no compassion for the humans. When Giovanni managed to find both Mewtwo and the others clones, he decided to help all of the Pokémon. It was proven to be a great ally for Ash and his friends. Later when Ash told it he will tell Professor Oak about him and the source, Mewtwo wanted to erased their memories again. But Meowth managed to convinced Mewtwo that they should keep their memories. Mewtwo agreed to let them remember it and the others, while only erasing the memory of the people who wanted to destroy Mewtwo.

The Mastermind of Mirage Pokémon

Main article: Mirage Mewtwo

Mewtwo makes an appearance as the secondary antagonist of the special The Mastermind of Mirage Pokémon. However, in this version, Mewtwo is a Mirage Pokémon created by Dr. Yung.

Other Appearances

Pokémon Origins

Mewtwo appears as the ultimate adversary of Red in Pokémon Origins. As in the games, it is encountered in Cerulean Cave after defeating Blue. In a hard battle that wiped out almost all of Red's Pokémon, Mewtwo is defeated by Charizard after it Mega Evolves into Mega Charizard X. With Mewtwo captured after several tries, Red then had all 150 known Pokémon.

Pokémon Adventures Manga

In the manga, Mewtwo was created during the Red, Blue, and Green story arc by the Gym Leader and Team Rocket's former scientist Blaine, who used one of his own cells in the process, though as a side effect, whenever Mewtwo fights it causes Blaine immense pain due to their cellular connection. Mewtwo first appeared attacking Blaine, and it was only with Red's strategy that Mewtwo is caught in a Pokéball.

In the Yellow arc, by this point Mewtwo and Blaine have become good friends and fight alongside Yellow against Lance of the Elite Four, but Blaine was forced to call it back before its fall due to their connection, though Yellow with Red's Chu (Pikachu) would use the same strategy Mewtwo tried earlier to win.

In the Gold, Silver, and Crystal arc during the Gym Leader completion, thanks to the powers of Entei's holy flames, Mewtwo's connection to Blaine is severed to where Mewtwo can now fight without affecting its creator, allowing it to leave Cinnabar Island and be free.

In the FireRed and LeafGreen arc, Mewtwo reappears and aids Red, Blue, Green, Yellow and Silver against Deoxys and Giovanni. In the end, it helped the Kanto Pokédex holders and Silver prevent Sird from recapturing Deoxys, and while the five of them were turned to stone, Mewtwo was not. It was mentioned by Sird in the Diamond and Pearl arc to have been tracking her before he lost her.

Mewtwo would later appear again in the X and Y arc where it is revealed that it had become the protector of Pokémon Village where it encounters Blue and the Kalos Pokédex holders, and Blue notices that Mewtwo has a mysterious new partner, later revealed as Blaine himself, who is capable of Mega Evolving it into Mega Mewtwo Y or Mega Mewtwo X depending on which Mega Stone that Mewtwo has equipped to itself.

Powers and Abilities

Mewtwo is highly skilled with Psychic powers. It can levitate through use of telekinesis]], speak telepathically, and can take control of another living being's mind. It has a powerful signature move, Psystrike (psychic wave manipulation), and it is also known for its powerful Shadow Ball and Aura Sphere. Mewtwo is also capable of wielding various types of attacks (but to a lesser extent than Mew). To exert its powerful psychic abilities, it will stay motionless for long periods of time in intense concentration to raise its capabilities to their maximum power.

In the Pokémon Adventures manga, Mewtwo fights with a highly skilled combination of Psywaves and a giant spoon for long range and close range battles, respectively.


  • In the original Japanese release of Mewtwo Strikes Back, Mewtwo is a very different character. He comes of as more sympathetic, with no intention to harm humans. He instead does the things he does in an effort to prove his own worth and believed superiority to the world.
  • The armor used to restrain Mewtwo in the FireRed and LeafGreen story arc of the Pokémon Adventures manga resembles the armor Mewtwo wore in the anime.
  • A journal quote from the Pokémon Mansion states that Mewtwo's birthday is February 6.
  • Mewtwo has a striking resemblance to Frieza and, to lesser extent, Beerus from the Dragon Ball Z series.
    • More directly, however, it bears a strong resemblance to the main antagonist of the Mother series, Giygas, particularly in his appearance in the first Mother (Earthbound Beginnings). A lot of the staff of that game had later worked on Pokémon.
  • Its personality traits and motivations, as well as its creation, were similar and/or somehow inspired by those of Shadow the Hedgehog in Sonic Adventure 2.
  • Mewtwo turning good at the end of Pokemon: The First Movie: Mewtwo Strikes Back is similar to that of Darth Vader in Star Wars Episode VI: Return of the Jedi.
  • Mewtwo is the only Pokémon able to learn Psystrike.
  • Mewtwo was also the first Pokémon to use Shadow Ball.
  • Although the official website for Genesect and the Legend Awakened claimed that the Mewtwo in the film was the same individual as in the first movie and Mewtwo Returns, both a prologue and flashbacks in the movie itself prove it to be completely different from it, including it being female in nature.
  • Mewtwo is the only villain in the Super Smash Bros. series that was dropped from one installment and then been brought back in the next.
  • Mewtwo, Wolf, and Dark Pit are the only antagonists in the Super Smash Bros. series to have never been starter characters.
  • Mewtwo is the only known Pokémon to become a Pokémon trainer.
