Pikachutwo was created by Mewtwo through cloning Ash's Pikachu's DNA and is the secondary antagonist of the first movie. He started fighting with Ash's Pikachu the minute he saw him, although Ash's Pikachu didn't like it. This happened at another time again; however, the two Pikachu became friends.
Mewtwo Strikes Back
Pikachutwo first appeared in the first Pokémon Movie, Mewtwo Strikes Back. After he was created, Pikachutwo attacked Ash's Pikachu, who didn't fight back. However, the battle came to a stop when Ash ran between Mewtwo's and Mew's attacks, which turned him to stone. Like all the other Pokémon, Pikachu felt utterly miserable about it.
However, the Pokémon's tears healed Ash. Mewtwo used his psychic abilities to lift Pikachutwo and the other clone Pokémon in the air, and they went away to find a safe home.
Later, after Team Rocket attempts to steal Ash's Pikachu, Pikachutwo comes to the place they crashed in. He uses Thunderbolt to stop Ash's Pikachu's Thunderbolt on Team Rocket. Then Pikachutwo goes on about how angry he is and tells Ash's Pikachu to leave. Meowth translates it all, one of the things being "Get out, or you'll regret it!" However, when Pikachutwo is about to attack, Mewtwo stops him by using psychic powers.
