Wario

Wario is Mario's self-proclaimed "rival" and evil doppelganger. Though he resembles an evil twin, the two are unrelated.

Unlike Mario, who is heroic and kind, Wario is greedy, lazy, and ill-mannered. He is hugely jealous of Mario's fame, and has frequently tried to steal enough wealth to make himself as beloved as Mario. Such plans almost always backfire, however. Mario has only directly fought Wario once; since then Wario's antics have occurred largely in the background of the rest of the Mario universe.

According to a comic story published in Nintendo Power, the reason Wario acts the way he does is because Mario, ironically, was a bully to him when he was young. Wario especially hated playing cowboys, because he was almost always the rustler that the sheriff, played by Mario, had to arrest.

The name "Wario" can be taken to be a blending of Mario's own name with the Japanese adjective warui (悪い) meaning "bad"; hence, a "bad Mario". In America, the name is often seen as being a play on the word "war" and the fact that the letter "W" resembles an upside down "M."

He first appeared in Super Mario Land 2 for the Game Boy as an antagonist who stole Mario's castle. Then Wario started appearing in his own series of games which include:
