How to Get Mewtwo in Pokemon Crystalby Arnold CarreiroUpdated September 22, 2017
Mewtwo, the Genetic Pokémon, was the strongest creature from the original three Pokémon games. You cannot access this angry psychic monster in the wild in “Pokémon Crystal Version,” but if you or a friend has already captured Mewtwo in one of the “Pokémon Red,” Pokémon Blue" or Pokémon Yellow” games, the violent creature can be transferred to the newer game easily. It doesn’t take too much effort to bring this old-school juggernaut into a new era of Pokémon adventures.
Capture Mewtwo at the end of Cerulean Cave after defeating the Elite Four in either “Pokémon Red,” “Pokémon Blue” or “Pokémon Yellow.”
Connect two Game Boy systems with a Game Link Cable. One Game Boy game must be the "Pokémon Crystal Version" and the other will be the "Red," "Blue" or "Yellow Version" or "Pokémon" containing Mewtwo. Insert the two game cartridges into the Game Boys and turn them on.
Go to any Pokecenter in both Game Boy games. You can begin trading with older versions of Pokémon after you have entered Ecruteak City in Crystal.
Walk upstairs to a nurse and confirm that you want to trade. In the Crystal Version, do not bring any Pokémon that were not in the Red, Blue or Yellow titles or the game will not allow you to trade.
Select any classic Pokémon on the Crystal game and Mewtwo in the other game and make the trade. Do not disconnect the cable until you receive a message permitting it. Save your games.
The cold-hearted Mewtwo was created in a science lab through grotesque experiments using Mew’s DNA. Mewtwo has a weakness to Bug-, Ghost- and Dark-type attacks.
