Pikatwo

Pikatwo (also known as Cloned Pikachu, Mewtwo's Pikachu or Pikachutwo), is an Electric-type Pokémon originally cloned from Ash's Pikachu. His name is never actually referred to in the anime (other than "Pikachu"), but it has been determined from the pattern of other clone Pokémon names (i.e. Mewtwo's name is a combination of Mew, the Pokémon it was originally cloned from, and the suffix "two". The same holds true for Bulbasaurtwo, Charmandertwo and Squirtletwo). He is not to be confused with the Pikachutwo from The Birth of Mewtwo radio drama, who was among Mewtwo's friends that died.
