Mewthree

The General is another (Shiny) Mewtwo (known as Mewthree in Lavender Town). Mewthree 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. Mewthree actually appears to be shiny, since he has a green stomach instead of the usual purple. Mewthree was seen defeating Ash's Tauros and preparing to use Selfdestruct on Squirtle, Bulbasaur, and Charizard after they destroy his substitute. The good Mewtwo arrived only to be caught by Brock in Ash's stolen Master Ball. It is then revealed that the Ash was an illusion to lure Mewtwo in. In the Vermillion Gym level, Mewthree tricks the three legendary dogs into coming onto the S.S. Anne. He says that he will "sing a little song" (later revealed to be Sing ) and that when they wake up, they will all be "friends". In the Celadon Gym level, it is mentioned by the future Celebi that the present-day Celebi is being mind-controlled by Mewthree. 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 is learned at level 86. This probably leaves Mewthree at level 86 or higher, which reinforces that it is strong indeed.

Trivia

 * Giovanni mentioned the creation of Mewthree in Lavender Town.
 * In the Pokemon Center, Mewtwo appears as a Bulbasaur since it has not been assigned a sprite yet.
 * Some people hacked it and try to scam people with it. This happened with Moltres as well.
 * Mewthree DOES infact have an important specific role to play in the future- He ends up taking a lot of pokemon from people and the player, along with Ash, Gary and Joey show up and use the pokemon to stop Mewthree( The result leaves Mewthree destroyed and he lies at the middle of a big crater near Saffron City. That is how it ends for a while- without much inference about where the trainers may be). This has been proved from Sam O. himself.
