Sega Superstars Tennis

Sega Superstars Tennis is a sports video game developed by Sumo Digital and published by Sega. It is the second title in the Sega All-Stars series, preceded by Sega Superstars (2004), and crosses over characters, locations, and soundtracks from several Sega franchises, including Sonic the Hedgehog, Space Channel 5, and Super Monkey Ball. It is the first and only Sega-themed tennis game to represent multiple franchises, and is the first game to feature Alex Kidd (Sega's former mascot) since the release of Alex Kidd in Shinobi World (1990).
