Pokémon - Der film: Mewtu gegen Mew

Mewtwo: The human sacrificed himself, to save the Pokemon. I pitted them against each other, but not until they set aside their differences did I see the true power they all share deep inside. I see now that the circumstances of one's birth are irrelevant; it is what you do with the gift of life that determines who you are.

[Japanese version]

Mewtwo: It's true... that you're a Pokémon who exists just like I do. It might be best if no one knew of this incident. It might be best to forget this.
