Where is the mewtwo event in Pokemon ash gray?

There is no Mewtwo event in Pokémon Ash Gray. This ROM hack is based on the original Pokémon FireRed and LeafGreen games and does not include any events from the anime.

The Mewtwo event you might be thinking of is from the anime series, where Ash and his friends encounter Mewtwo in the movie *Pokémon: The First Movie*.

If you're looking for ways to get Mewtwo in Ash Gray, you'll need to find it in the game's world or use a cheat code.
