There's a reason Mewtwo has stayed relevant since Gen 1. Psychic typing and outspeeds nearly everything without investment — it checks a lot of boxes at once. Only weak to Bug, Ghost, and Dark. Known as the Genetic Pokemon.
Mewtwo's built around special offense. Sp. Atk leads the charge, Defense pays for it. Near-impossible to catch, worth 3 Sp. Atk stat exp. Follows a slow 1.25M XP grind.
Said to rest quietly in an undiscovered cave, this POKéMON was created solely for battling.
