Wario is a rival and anti-hero caricature of Mario, designed as an over-the-top evil-looking character. He is selfish, vengeful, traitorous, insecure, spiteful, stingy, wrathful, and destructive, often motivated by greed to hunt treasures and maim thieves. Despite his brute nature, he is cunning, intelligent at times, a shrewd businessman, master pilot, and talented hypnotist. He has known Mario since childhood, harbors a rivalry, and engages in vigorous exercise. Wario transitioned from villain to anti-hero, participating in sports and kart races, though he is a poor sport who brags when winning and accuses others of cheating when losing.
