–Mewtwo in the film Mewtwo Strikes Back
As shown at the beginning of Mewtwo Strikes Back, Mewtwo has been created by a group of scientists led by Dr. Fuji. Its companion in these early days was Ambertwo, a clone of Fuji's deceased daughter Amber who sadly perished much like the girl she was cloned from. After learning that the scientists regard it a merely an experiment and not as a living creature of worth it becomes filled with rage. It destroys the laboratory, and is approached by the arriving Giovanni with an offer to learn to control its powers. With some sort of armor on, Mewtwo is used in The Battle of the Badge against Gary Oak in a gym battle after aiding Giovanni in a series of other victories. Gary describes it as an "evil" Pokémon to Ash Ketchum, who doesn't get the chance to see it. Mewtwo escapes from Giovanni after finding out that they aren't partners, but that Giovanni regards it as a weapon. It levels Giovanni's mansion and destroys his armor in the process, and is seen briefly by Jessie and James in It's Mr. Mime Time!
Mewtwo Strikes Back
Mewtwo subsequently returns to its birthplace, New Island, and rebuilds the lab it destroyed into a massive castle. It kidnaps the Nurse Joy of the nearest Pokémon Center, and takes control of her mind. After gaining her help in preparing for its plan to create an army of Cloned Pokémon, it has her send invitation discs to some strong Trainers. The Trainers go through a storm that Mewtwo caused as a test, with the storm's true purpose being to wipe out all humans and those Pokémon not created through cloning as Mewtwo and his army were, as it considers natural Pokémon weak due to their willingness to serve or befriend humans. Once the trainers arrive, Mewtwo reveals itself, claiming to be both the world's strongest Pokémon trainer and the world's most powerful Pokémon.
After proving itself more than a match for several of the Pokémon assembled on the island, Mewtwo releases Nurse Joy from its control. It then accepts a challenge from Ash to prove the superiority of its cloned Pokémon, and unleashes cloned versions of Charizard, Blastoise, and Venusaur to challenge natural versions partnered with Ash and two of the other trainers. Upon achieving victory, Mewtwo captures all the trainers' Pokémon and clones them to create its army of clones, and informs the humans that it will spare them, but that they will be consumed by the storm like the rest of the planet. However, Ash then arrives with the freed natural Pokémon to challenge him, only for a far more startling opponent to appear: a living Mew.
Mewtwo challenges Mew to a battle, determined to prove that it is the superior Pokémon, which leads to a battle between the two and their respective groups of Pokémon. Using their psychic abilities, the pair suppress the abilities of the Pokémon under their leadership and engage in battle. Blind to the suffering of both sides, the two continue to clash until Ash rushes between them in a desperate attempt to stop the fighting. Their blasts render Ash inert in a stone-like state, from which it is revived by the tears of natural and cloned Pokémon alike. This sight enables Mewtwo to realize that it is one's choices, not the circumstances of their birth, that determines their identity. Dissipating its storm, it then departs with its clone army and returns the humans and their Pokémon to their proper places, erasing their memories of encountering it.
In Mewtwo Returns, the clones have found a lovely place to live, on top of Johto's largest mountain. They could live there in peace, but Giovanni finds them. In the end he departs the other cloned Pokémon so they can live peacefully as wild Pokémon. He is then seen in a unknown city at night.
Mewtwo's uniqueness largely stems from its psychic abilities. However, its personality is one of the defining points in the Pokémon series. Mewtwo's personality is initially complex involving existentialist anxiety, and contemplating the meaning of existence. Its temperament is very introverted, consisting of hate and anger towards humans and its creators.
Having been brought into existence through artificial means, Mewtwo quickly turned on its creators when he learned that they intended to experiment on him further. Feeling betrayed by the very humans that had created it, it decided to forge its own path. The recurring theme in the movies is Mewtwo harboring jealousy towards Mew because it is a copy or derivative, whereas Mew is the original.
In the first movie, the path that Mewtwo has taken makes him into a rather immoral character. It frequently exhibits cruelty, and, at several intervals, goes so far as to attempt to (or forthrightly) kill those who oppose it. It also shows no qualms about forcing Nurse Joy to serve as its puppet, and then casting her aside once she was of no further use to it. This makes Mewtwo easily one of the most malicious characters in the series and the main antagonist in Pokémon The First Movie, prior to its change of heart at the end of the first movie.
However, in Mewtwo Returns, it is much more kind, and only wants to protect the other clones that it created. It even protected some humans that were on a bus getting thrown around by strong winds. Therefore Mewtwo is a hero in its second movie, and a victim. When Giovanni comes on the mountain, Mewtwo is willing to sacrifice itself to save the other clones, as well as Ash's Pikachu and Team Rocket's Meowth. Also, it constantly wants to avoid fighting, which is the exact opposite of the way he was in the first movie.
So, it can be said that Mewtwo, upon Ash's sacrifice in Mewtwo Strikes Back, has become a hero instead of a villain. It continues to live in Johto and, as said by itself, "in shadows".
