TYPE: Human, Boss.
CLOSE RELATIVES: None.
SKILLS AND ATTACKS: Shoulder Bash.
STRENGTHS: He's strong against fire (in Super Mario Land 2) and he's virtually indestructible in many Wario Land games.
WEAKNESSES: His greed?
BACKGROUND: Picture a bigger, fatter, Mario wearing yellow clothes, a crooked moustache, and a "W" on his cap and "POOF!" there's Wario. He's been arch rivals with the portly plumber since childhood and steals Mario's castle (Castle? Why doesn't Mario live there instead of his dinky little cottage?) later on in life. Mario takes it back, of course, and in WL, Wario searches for a new castle. This game sent out a world wide, hand held craze, and since then, the saga of the greedy Wario has had 3 sequels and counting. Wario went on to start his own game-development company which has churned out five "Wario Ware" games.
EVOLUTION: In Wario Land, Wario shrank say, FOUR TIMES (!) an now sported an explorer's hat with a "W" on it. In WL2, he changed back to the cap we all know and love. In WL3, he put on a little weight. Nothing really changed in WL4.
