Waluigi

Waluigi is a character debuting in Mario Tennis. He is the lanky rival of Luigi and a partner of Wario. Since his introduction, Waluigi has been playable only in spinoff games of the Super Mario franchise. He was voiced by Charles Martinet from his debut to Mario Strikers: Battle League, after which he was replaced by Kevin Afghani in Super Mario Party Jamboree.[1] Waluigi was originally conceptualized as Wario's brother[2] and referred to as such in some early material.[3][4][5][6] However, later sources have instead described them merely as partners,[7] including the Mario & Sonic series containing several explicit statements that the two are unrelated.[8] The above text is from the Super Mario Wiki and is available under a Creative Commons license.
