Overview

Mewtwo is a powerful Psychic-type Pokémon associated with scientific attempts to create a new being from Mew-related material. Its humanoid body and pronounced tail distinguish it from Mew's smaller form. The original game's environmental clues make its origin a story discovered through records and exploration, rather than only a numerical statement about a rare encounter.

The first film gives Mewtwo a developed conflict over identity and the treatment of created life. That adaptation is not a direct transcript of every game's events. Mega forms and later depictions add further versions, so this entry separates the species or named being's game identity from the screen character's particular philosophy, powers and eventual choices.
