Wario

Actual Background
Wario is seen as a baby in Yoshi's Island DS, which was released many years after his first appearance as an adult in Super Mario Land 2: 6 Golden Coins. As a child, Baby Wario is prone to tantrums, and already has a penchant for riches. He is kidnapped along with all the other children of theMushroom Kingdom by Kamek, and after some adventures with Yoshi and a group of Bandits, Wario is last seen arguing with Baby Bowser on a barge filled with treasure. Wario is very powerful; his weight and strength are often emphasized in the games he appears in, especially his own. He owns a number of vehicles, including two cars, a tractor, a plane, and a bike. He tends to name some of said vehicles after animals. Wario is very greedy, even with riches, he strives for more, which leads him to do some evil. Otherwise, he generally leaves people alone.

Wario In Gamed9x's Series
Wario tends to enjoy money, but that's only half of him. Wario has up to 3 split personalities. This includes Real Wario, Deep Voiced Wario [the one who says D'oh I missed], and Vibrant Wario. This was introduced in the second episode of Mario Party. He also likes to rig games, but not as much as Mario does.
