Scientists were working to create an even stronger version of Mewtwo, and they succeeded. But maybe it wasn't a good idea... Mewthree exists outside of our universe, filled with Exergy, a strange form of energy.
Ability: Silent Rage: Becomes Stronger as the battle goes on. (raises all stats every turn)
Signature Move: Raw Exergy: Power: 180 Category:Special : Type: ??? The user exposes the target to a strange form of energy known as Exergy.. However, this lowers the user's Defense, Sp. Def, and Speed stats.
I don't think it looks that good... But at least it's something!
