Wario (?) is a fictional Nintendo video game character created by Gunpei Yokoi. Wario was designed as another antagonist to Mario (besides Bowser), and first appeared in the 1992 handheld video game Super Mario Land 2: 6 Golden Coins as the main antagonist and final boss. Since that time, Wario has developed into the protagonist and antihero of the Wario Land series, spanning handheld and home console markets, in addition to his numerous appearances in spin-offs in the Mario series.
He is voiced by Charles Martinet, who also voices Mario, Luigi, and Waluigi. In most of Wario's adventure games, his actions are selfish and greedy, but he consequently does good deeds to get what he wants, the antagonizing force being an obstacle. Wario's personality and actions are often the opposite of Mario's typical heroism and kindness, just as the first letters in their names appear to be opposites.
The name "Wario" is a blending of Mario's name with the Japanese adjective warui () meaning "bad"; hence, a "bad Mario".
