Black Dragon

The Black Dragon is one of the eight items that Wario can purchase from the Item Shop (nine, if the Smile counts) in the Game Boy Advance game Wario Land 4. The shop keeper, Mr. Game & Watch, sells Wario these items to assist him in defeating a challenging boss by doing pre-damage at the battle's start. It costs 10 Frog Medals to purchase. The price may be higher, depending on the game mode.

Effect
When purchased, Mr. Game & Watch will follow Wario into the Boss Room. He will then transform into a black dragon, which then breathes fire on the boss. After the damage is done, Mr. Game & Watch then disappears, leaving Wario to fight a greatly weakened boss.

The damage varies depending on the boss, but it is most effective against Cractus, dealing 10 damage.
