They first appeared in the game of the same name as robbers; although the reasoning differed among various versions, they were generally depicted as opposing other criminal organizations for the greater good. They made appearances alongside Sonic in Sonic & SEGA All-Stars Racing and Sonic & All-Stars Racing Transformed.
