Silas Volkmire is in Battletoads in Battlemaniacs as the secondary villain, though the 'Toads never fight him directly. In Battlemaniacs, he uses Psicone's TRIPS 21 system to send Psyko-Pigs out and capture Michiko and Zitz. Pimple and Rash are then forced to play within Silas's game. In the final part of the game, Silas slips back to Earth and the 'Toads have to destroy his escape ship before it escapes. Whether or not they're successful will result in different endings.
