Vinnie

Vinnie suffered severe injuries during the war on Mars against the Plutarchs. In the same incident where his brothers were wounded, he lost the right side of his face. His mission isn't just to destroy the monsters Limburger brings from space, but also to conceal his identity from human society (though almost everyone in Chicago seems to get used to seeing giant mice on motorcycles pretty quickly). Vinnie approaches this mission with a personal dose of revenge, seeing each victory over Limburger as a small recompense for what they did to his face and his family on Mars. Now that time has passed, he has a new objective, new conflicts: to return Princess Piper to her planet as soon as possible (her presence bothers him since her arrival because she is capricious, demanding, and ruins his jokes) and to survive the hunt by Carbine and the galactic nations who believe they are responsible for the kidnapping.
