Type: Normal/Fighting
Classification: Rabbit Pokémon
Height: 1.3m
Weight: 28.3kg
Ability: Scrappy
Mega Lopunny's wild fighting instincts, long dormant, have been awakened! A full-power strike from its ears could crumple solid steel plates. Its personality transforms and becomes extremely aggressive, which often leaves its Trainer feeling bewildered by the change.
Lopunny's Attack gets a huge boost from Mega Evolution, and its already-high Speed also increases. With the Scrappy Ability, its Normal- and Fighting-type moves will even hit Ghost-type Pokémon.
