Mega Chesnaught

Bulletproof blocks ball-type and bomb-type moves entirely. Sludge Bomb, Power Gem, Flash Cannon, and Aura Sphere become dead moves against Mega Chesnaught. Spiky Shield damages contact attackers while blocking moves, punishing physical attackers for closing in. Leech Seed drains HP every turn for sustained recovery in Rain. Body Press deals damage scaling with the massive Defense investment. Wood Hammer provides high-power Grass STAB for offense. Impish maxed HP and Defense creates extreme physical bulk. Rain halves Fire damage, removing Chesnaught's most dangerous weakness and enabling the prolonged Leech Seed drain game plan against most team compositions.
