Wario

Wario is one of the anti-heroes in the Mario series. He and his brother Waluigi are shown to be related cousins with Mario and Luigi, whilst being rivals with the Mario Bros.

Appearance
Wario appears to be a shorter fatter version of Mario, however, with a yellow cap with a blue 'W' on it, purple overalls with white buttons and a yellow shirt underneath, and wears green shoes. He also has a big pink nose and a pointed mustache.

Personality
Wario typically has a natural greed for money, which also balance's out for his competitive side when it comes to having a competition with Mario, Wario also has quite the temper, when he usually gets into a typical rival competition, or if he loses or tries to best Mario.

In Wario games, he is generally lazy, ruthless and greedy. He is foul and smelly, as he eats a lot of garlic, his favorite food. When there is an opportunity to obtain treasure, or vast amount of fortune, he usually is determined to get it. Despite all of this, Wario plays the role of an anti-hero, or neutral character, with the exception of Super Smash Bros. Brawl, in which he fights along side Bowser and Ganondorf, only to aid the player later on. He has been cast as a hero when fighting others who are more villainous, which have made his personal and moral flaws seem smaller. He is only interested in saving the day when it means fortune for him or a way home

His fierce competitiveness is fueled by the jealousy towards Mario. In later years after their initial encounter the tension between has weakened, but it still remains. Wario has allied with Mario to defeat greater threats in Super Mario 64 DS. According to the comic Super Mario Adventures, Wario has hated Mario since they were both young, Mario bullied Wario with dirty pranks, such as making Wario pick up Piranha plants while, on his side, picking up turnips. According to Nintendo Mario and Wario have known each other before Wario stole his castle, though if the comic is correct or not is still open for debate. Sometimes, Wario gains a begrudging respect to Mario and his desire to beat him rather than kill him. However in Mario Super Sluggers, he actaully does. He appears to have a crush on Peach and declares to win her heart and wishes that she will be like him, much to Mario's annoyance.
