Big Fist

The Big Fist is an item that Wario can purchase from the Item Shop in the Game Boy Advance platform game, Wario Land 4. It can be bought off the Shop Keeper, Mr. Game & Watch, for 10 Frog Medals (depending on the game mode, it could cost more). All items from the Item Shop are used to assist Wario in defeating a boss by doing pre-damage at the battle's start.

Effect
When purchased, Mr. Game & Watch will follow Wario to the Boss Room. He will transform into a big fist, which will then swing a powerful punch at the boss. Mr. Game & Watch will then disappear, leaving Wario to fight a greatly weakened boss.

Damage varies depending on the boss, but it is most effective against Cuckoo Condor, dealing 12 damage.

Trivia

 * The Big Fist resembles to Master Hand and Crazy Hand from the Super Smash Bros. series.
