Mario Tennis: Power Tour
Mario Tennis: Power Tour (also known as Mario Power Tennis in Europe and Australia, and as Mario Tennis Advance (マリオテニスアドバンス Mario Tenisu Adobansu) in Japan) is the Game Boy Advance counterpart of Mario Power Tennis for the GameCube, and the final Mario release for the said handheld. It is very similar to Mario Tennis in gameplay and plot, though it has the addition of Power Shots. Though it is the counterpart of Mario Power Tennis, the two games cannot be connected in any way.
The player, either Clay (Max in Europe) or Ace (Tina in Europe), is a student in the Royal Tennis Academy. During this time, masked challengers come to the academy and defeat the academy's champions, leaving everyone in disbelief as they have never lost before. Determined to find out who they are, Clay and Ace become a part of the Junior class, where they defeat everyone in it. They continue on to the Senior classes, and then to Varsity, where they learn that the top two doubles teams (or players, if it its singles) get to advance to the Island Open, where they would play against top students from the other two tennis schools.
Clay and Ace soon ensures their entry to the Island Open. They hear a rumour that the victors of the Open would get a chance to play against Mario. During the time at the Open, the player may wish to travel between the Academy and the area of the Open at any time. After winning the Open, Clay and Ace realise that they still have not discovered who the masked plays are. However, the very next day Mario comes to the Academy, and gives Clay and Ace the honour of playing with them. Thus begins the Peach Tournament, with Clay and Ace as players. Clay and Ace travel to the Mushroom Kingdom by the Toad Express, where the games are being held in the Peach Dome, owned by Princess Peach. During their stay, Clay and Ace are told that it is Mario and company that were the masked players in the academy, and that it is also them that introduced the concept of power shots to Earth. Piantas, Toads, and Nokis are present at the dome as part of the audience.
Single player mode is relatively similar.
 Playable Characters
Though the game features many characters, the game seems more like a Mario cameo than an actual Mario game on the account that only 6 Mario characters are playable, while getting rid of three out of 9 of the most popular characters, which are Wario, Yoshi and Daisy. This makes it the only time Waluigi has appeared without Wario. None of the unlockable characters are Mario characters, although star versions of them can be unlocked.
 Non-Playable Characters
