Mewtwo

Description
Mewtwo is a Pokémon that was created by genetic manipulation. However, even though the scientific power of humans created this Pokémon's body, they failed to endow Mewtwo with a compassionate heart. Its DNA is almost the same as Mew's. However, its size and disposition are vastly different. It is known to be the most powerful pokemon in the world.

Storyline
There are actually two Mewtwos in the game. One appeared in the Cutscene before Pewter Gym to help you save Joey and says that he has got a friend who teaches him teletransport. A shiny Mewtwo appears in the Cutscene for Cerulean Gym 2, revealing himself to be the one behind the attacks by Team Rocket, the gym leaders, and the aforementioned "General".



The General
The General is another Mewtwo. The General was made in the same lab as Mewtwo and escaped when Mewtwo destroyed it. His makers planned to destroy him because he would not listen to them. At first he admired Mewtwo, but did not understand why he turned to the side of good and decided to start wreaking havoc himself. The General actually appears to be shiny, since he has a green stomach instead of the usual purple. General Mewtwo was last seen defeating Ash's Tauros and preparing to use selfdestruct on Squirtle, Bulbasaur, and Charizard after they destroy his substitute. His level is not known, although one can infer from its moves and what level it learns them. In this case, Selfdestruct and Substitute are curiously only learned as TMs, but Recover typically appears around level 80. This probably leaves the General at level 80 or higher, which reinforces that it is strong indeed. {C
