Mario Tennis: Power Tour, (entitled Mario Power Tennis in Europe), is the fifth installment in the Mario Tennis series, and the third to hit a handheld system (if the Virtual Boy version is counted). It is also the final Mario game on the Game Boy Advance.
Though the game features many characters, the game seems more like an unofficial Mario game than an official game. The reasoning is that only six Mario-related characters are playable, while getting rid of four out of nine of the most popular characters, which are Wario, Yoshi, Toad and Daisy.
