>Mewtwo's personality and goal are different between the original and dub. In the dub, Mewtwo is more boastful about its powers and certain about superiority to Mew and wants to destroy the world with a hurricane it created to get revenge on humanity. In the original, Mewtwo is instead portrayed as a confused being and, while its motive is still to get revenge on humanity, it is not the destruction of the world by means of the storm, but the actual confrontation between Mewtwo and the trainers that is its goal, with the storm used as a test that the trainers had to get through.>In the dub, Mew is portrayed more as a hero to counter Mewtwo, contrasting the original where it has more anti-heroic qualities. Due to this, Mew's speech to Mewtwo is different in the Japanese version. In the English dub, Mew says that shows of force prove nothing, and real strength comes from the heart. In the original, Mew is much more bellicose, saying that only the original Pokémon are real, and no matter how much they fight, the real ones will never lose to copies.Couldn't find anything about the moral.
