The Robot Battle Royale is a robot fighting tournament where amateur and professional inventors can compete against each other using self-made robots in outright death matches. Mayor Fink serves as the host and overseer.[1]


In the Robot Battle Royale, eight participants compete in a single-elimination tournament bracket. Each participant fight each other using one robot of their own. A robot which is unable to fight or knocked out of the ring is eliminated. The rules are that anything goes, so any trick is allowed. However, contestants have to hand in their robots' override codes to avoid unfair advantages (although this does not prohibit usage of them).[1]

When the Robot Battle Royale was held for the Village to see, Dr. Eggman and his miniature Obliterator Bot, Tails and Hypnobot, and amateur inventor Knuckles and his Vacuu-Fan 2000 joined the competition. While Knuckles quickly lost, Tails and Eggman got to the finals where Eggman won unfairly by taking over Hypnobot using its stolen override code. Eggman then left to use Hypnobot's abilities to seize control of Tails' other inventions.[1]
