Wario is a fictional character in Nintendo's Mario series, designed as an arch-rival to Mario. He first appeared in the 1992 Game Boy game Super Mario Land 2: 6 Golden Coins as the main antagonist and final boss. His name is a portmanteau of Mario's name and the Japanese word warui (悪い), meaning "bad". Wario was designed by Hiroji Kiyotake, and is voiced by Charles Martinet, who voices many other characters in the series, such as Mario, Luigi, and Waluigi.
