Mewtwo (Japanese: ミュウツー Mewtwo) is a Psychic-type legendary Pokémon cloned from a Mew.

The story of Mewtwo is chronicled in the CD drama The Birth of Mewtwo, the movie Mewtwo Strikes Back, the television special Mewtwo Returns, and the bonus short from Mewtwo Returns titled The Uncut Story Of Mewtwo's Origin. It made a brief appearance in the anime in The Battle of the Badge, when Giovanni used it to defeat Gary Oak, and in Showdown at the Po-ké Corral, where it escapes from Team Rocket HQ (a scene also chronicled in Mewtwo Strikes Back, and later seen again in Mewtwo Returns).


Young Mewtwo crying as Ambertwo dies

Approximately twenty years before the present, Team Rocket discovered that a Mew was living in Guyana. Many years later, under the orders of its new leader, Giovanni, Rocket members went back to the area to search for Fossils. They succeeded in finding an eyelash belonging to Mew. Giovanni asked Dr. Fuji to clone Mew for him. Fuji agreed because he wanted to use Team Rocket's research funds to attempt to clone his deceased daughter, Amber.

One month after the discovery of the eyelash, Mewtwo was successfully created and was stored at New Island. At this point, it was still not fully grown and lived in a large test tube alongside a tube containing Ambertwo. Fuji and Giovanni thought Mewtwo was sleeping inside its tube, but it was able to communicate telepathically with Ambertwo. However, because the lifeforce of a human is not as strong as a Pokémon's, the Amber clone died. Mewtwo also grew alongside three other clones, a Bulbasaurtwo, Squirtletwo, and Charmandertwo. However, these clones died shortly before the Amber clone, suggesting that Mewtwo's lifeforce is even stronger than a normal Pokémon's.

Eventually, Mewtwo fully matured and broke out of its test tube. Those responsible for its creation were happy that they succeeded in their goal of creating the world's most powerful Pokémon. Enraged and confused about the circumstances that led to its creation and powers, Mewtwo attacked the scientists on New Island. Despite the efforts of security systems that attempted to control it, Mewtwo destroyed the island and all the scientists on it.

In his robotic suit, under observance by Giovanni

Immediately thereafter, Giovanni found Mewtwo and convinced it to help with Team Rocket's goal of controlling the world. Mewtwo's power was focused, as well as weakened and controlled, by a robotic suit of armor as it performed tasks such as battling under Giovanni within the Viridian Gym and helping Team Rocket capture Pokémon. Eventually Mewtwo became tired of being used by Giovanni. It developed a strong hatred for humans, and thought that they were weak and selfish beings only interested in power and wealth; it also despised the Pokémon who served humans. It escaped from Giovanni, destroying Team Rocket headquarters in the process, and relocated to its birthplace on New Island, where it built its own headquarters. Mewtwo then issued a challenge to several strong Pokémon Trainers, including Ash Ketchum. It used its powers to create a storm that would serve as a test to see who could make it to the island. Only a handful of Trainers managed to brave the storm and arrive, including Ash and his friends. Upon revealing itself, Mewtwo challenged the Trainers with a Venusaur, Blastoise, and Charizard (all cloned) to prove its superiority to human Trainers and the superiority of cloned Pokémon to trained Pokémon. To do this, Mewtwo used a variation of the Poké Balls used by Trainers. Once caught in the Balls, the Pokémon that had been brought to the island were cloned in an upstairs laboratory. However, before Mewtwo could defeat the Trainers and move out into the world, Mew appeared. The two Pokémon fought and ceased battle when Ash was caught in their crossfire and turned to stone. After Ash is revived by the tears of the nearby Pokémon, clone and original alike, Mewtwo experiences a change of heart and stops its destructive rampage. Wanting to find itself, Mewtwo erased the memories of those present and, along with all the other clones, left New Island for Johto, eventually settling on Mount Quena. During this time, presumably to prevent any chance of any humans encountering them, it frequently enclosed the mountain with a severe storm. However, it isn't willing to allow a bus full of humans to die from being knocked off course, using its telekinesis to place the bus back on the road, namely because that would result in more humans arriving to investigate for, and help, any survivors, thus making it even more risky, although the clone Meowth believes that Mewtwo also did it due to a growing soft spot for humanity.

Wearing his cape during the introductory sequence of Jirachi: Wish Maker

A few years later, Giovanni found Mewtwo's hiding place via one of their satellites and began a plan to capture it once again. However, this plan was foiled when Mewtwo again met with Ash, who did not remember their previous encounter. Giovanni restrained Mewtwo, but his friends helped it to escape and defeat Giovanni. At the end of the ordeal, Mewtwo erased Giovanni and his soldiers' memories of it, and decided to move throughout the world searching for the meaning of its life.

In the epilogue to Mewtwo Returns and in some TV series opening sequences and movie previews, Mewtwo has been seen wearing a plain brown cape and moving across rooftops at night.

Mewtwo also had a passing mention in the special The Mastermind of Mirage Pokémon, when the mirage Mewtwo was created, Mirage Master claimed "This is not the Mewtwo you are familiar with", possibly meaning he saw Pikachu's memory of Mewtwo.

Mewtwo overlooking a city at the end of Mewtwo Returns
  • In the first movie, Mewtwo used Shadow Ball despite this move not being released at the time.
  • The city that Mewtwo is seen overlooking at the end of Mewtwo Returns bears a great resemblance to real life New York City. Buildings that resemble the Chrysler Building and MetLife Building can be seen in the distance. The narrator refers to it as "a far away city."
