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 EVs. Follows a slow 1.25M XP grind.
Because its battle abilities were raised to the ultimate level, it thinks only of defeating its foes.
It usually remains motionless to conserve energy, so that it may unleash its full power in battle.
Mewtwo Weakness
VulnerableType-wise, Mewtwo takes extra damage from Bug, Ghost, and Dark. Mewtwo's overall bulk (106/90/90) lets it take a hit or two from most weaknesses before going down.
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
- Special stat split into Sp.Atk and Sp.Def
