Wario

First Appearance

Super Mario Land II: 6 Golden Coins

1992

The rival of the mascot of Nintendo is one who we have certainly not seen the last of. He's a major pain for Mario, but has also helped him on several occasions. Because of his unique personality, he now has 2 of his own series of games: Wario Land and Wario Ware. The Wario Land series isn't anything too special, being somewhat similar to Mario games. However, Wario Ware is a recent series that is really entertaining, playing mini-games in a "bop-it" style.
