Big Fist

The Big Fist is an item that Wario can purchase from the Item Shop in the Game Boy Advance game, Wario Land 4. It can be bought off the shopkeeper, Princess Game & Watch, for ten Frog Medals (depending on the game mode, it could cost more). All items from the Item Shop are there to assist Wario in defeating a boss by doing pre-damage at the battle's start.

Effect
When purchased, Princess Game & Watch will follow Wario to the boss room. She will the transform into a big fist, vaguely resembling Master Hand and Crazy Hand from the Super Smash Bros. series. The fist will swing a powerful punch at the boss, although the damage varies depending on the boss, it is most effective against Cuckoo Condor, dealing 12 damage. After punching the boss, Princess Game & Watch exits the room and Wario is left to challenge a greatly weakened boss.
