Wario Land 4

Wario Land 4 is a Game Boy Advance video game released in 2001. It is, as the name implies, the fourth game in the Wario Land series, which is a spin-off of the Super Mario Land series. In the game, Wario advances through the levels through transformations triggered by enemy attacks. This is the first Wario Land game to feature hit points - in previous games, it was impossible for Wario to die. However, he does have infinite lives.

Story
Wario sees an article in the morning paper about a treasure that has been uncovered in a golden ziggurat in the jungle. He runs there to claim the treasure for himself. He ends up locked in several epic battles, aided by a figure resembling Mr. Game & Watch, and rescuing the spirit of an ancient princess who had been locked away thousands of years earlier. Wario finally arrives back home, much richer.
