Alex Kidd

Alex Kidd was Sega's previous mascot until the Sega Genesis reached fame and Sonic the Hedgehog replaced him. Alex Kidd's most prominent features are his large pointed ears, red jumpsuit and enormous sideburns.

Segagaga
Segagaga is a Dreamcast game where you get to take control of Sega to help it win the video game war. (Naturally, this was before they bowed out of the console race back in 2001.) At one point, you run into Alex Kidd, who relates his sob story of how he used to be the mascot of Sega, but was demoted in favor of Sonic the Hedgehog. Instead of starring in video games, he's now forced to work retail at one of Sega's shops. This is a sad yet comical look at Alex Kidd.

Sega Superstars Tennis
Alex Kidd appears in this game as an unlockable, playable character. This game marks his first playable 3-D appearance.

Sonic & Sega All-Stars Racing
Alex Kidd is a playable character in the multi-platform racer Sonic & Sega All-Stars Racing. He rides a red motorcycle named "Sukopako". For his All-Star move, he hops into a pedal-powered gyro-copter named the "Peticopter", allowing him to fly and shoot damaging projectiles at opponents.

Sonic & All-Stars Racing Transformed
Alex Kidd is an unlockable character in Sonic & All-Stars Racing Transformed that unlocks automatically when the system's clock reads any time after December 25, 2012. Because they were released after this date, the Steam and 3DS versions have Alex Kidd available from the start. His traditional red and yellow jumpsuit is replaced with a Santa Claus outfit (which consists of a red Santa coat, black boots, white gloves, and brown belt with a golden belt buckle) to reflect his status as a holiday bonus. His All-Star Move involves "Rock, Paper, Scissors" firing two gigantic hands out from the sides of his vehicle, hitting adjacent racers

Trivia

 * The character Chip from Sonic Unleashed has similar appearances to the Alex Kidd version off of Segagaga.
 * Alex Kidd seems to have some monkey-like features, having large ears and hands, as well as having thick brown hair with prominent sideburns. This is probably because he is based on Sun Wukong, the main protagontist of a Chinese folk tale.
