Mewtwo can be caught in "Pokémon HeartGold" and "SoulSilver" in the same location as before after defeating all of the gym leaders in Kanto. The character was also the focus of a promotion and downloadable content giveaway for "Pokémon Black" and "White". It was also said to be under a truck in one of the cities, though this was revealed to be a hoax. Mewtwo also reappears in "Pokémon X" and "Y" after completing the main story, and is one of the handful of Pokémon capable of using the new Mega Evolution mechanic, as it can transform into either Mega Mewtwo X or Mega Mewtwo Y.
