Wario is a fictional character in Nintendo's Mario series. The character was designed as another antagonist to Mario (besides Bowser), and first appeared in the 1992Game Boy title Super Mario Land 2: 6 Golden Coins as the main antagonist and final boss. He was portrayed as an exaggerated version of Mario and his name is a variant of Mario's name (as shown by the W in his name, which is an upside down M that portrays him as an upside down Mario).
