The Biker Mice are Throttle, Modo, and Vinnie. Refugees from Mars, they fought in a rebel group called the Freedom Fighters during a war against the Plutarkians, a race of stinking fish-faced aliens who steal natural resources from other planets and ship them back to their own. The Martians lost the war, and their planet was devastated. Now in Chicago, the mice fight Lawrence Limburger, who is himself a Plutarkian in disguise. -- from the 'From Mars' website
