Robo Mario

Robo Mario is a robotic entity that resembles Mario, created by Professor E. Gadd (as evidenced by the logo on his cap). He first appeared in Mario Kart Arcade GP, then reappeared in Mario Kart Arcade GP 2. Two versions of Robo Mario exist: a black version and a silver version.

Mario Kart Arcade GP
In Mario Kart Arcade GP, the black version of Robo Mario appears in the challenge game in Rainbow Cup, and the silver version of Robo Mario appears in the challenge game in Special Rainbow Cup. Both challenge games occur on Rainbow Coaster with the objective of beating Robo Mario while dodging his attacks. There are no Item Boxes in this course, so while the player cannot attack Robo Mario, Robo Mario can spawn an infinite number of items to attack the player. When Robo Mario is in the lead, he drops Bananas to slow down the player. If the player is in the lead, Robo Mario either uses a Green Shell or a Black Shell to attack his opponent.

Robo Mario is the first racer in the Mario Kart series to be exclusive to the CPU; this distinction would later be shared with Wario and Bowser in Mario Kart Arcade GP VR, and Bowser Jr. and the Koopalings in Mario Kart Live: Home Circuit.

Mario Kart Arcade GP 2
Both versions of Robo Mario reappear in the sequel, Mario Kart Arcade GP 2, having the same roles as in its predecessor. The black version of Robo Mario appears in the challenge game in Rainbow Cup, and the silver version of Robo Mario appears in the challenge game in Special Rainbow Cup.

Trivia

 * A discrepancy can be seen regarding the emblem featured on Robo Mario's kart: official artwork depicts the kart with Professor E. Gadd's logo, while the in-game model shows it with Mario's logo. This is due to Robo Mario reusing Mario's gold kart model rather than having his own.
 * The black version of Robo Mario always appears in the image accompanying the instructions for the Robo Mario challenge game, regardless of which version of Robo Mario will be challenged by the player.
