Mario was originally portrayed as a two-dimensional sprite, but in later games, he is shown as a three-dimensional, polygonal model. He is depicted as a portly plumber who lives in the fictional land of the Mushroom Kingdom with Luigi, his younger, taller brother. In the television series and film, Mario and Luigi are originally from Brooklyn, New York. Little is known of Mario's childhood, though the infant version of Mario, Baby Mario, first appeared in 1995 in Super Mario World 2: Yoshi's Island, and has often appeared in Nintendo sports games since that time. Baby Mario has a major role along with Baby Luigi in Mario & Luigi: Partners in Time and appears in Yoshi's Island DS. He (along with the adult Mario) is voiced by Charles Martinet.
