Defending Champions of Robot Arena Here's who you'll be up against in the seven-level tournament of bashing and smashing:   Controlled by a man known only as "The Warlock," Aquarius has an eerie way of disturbing your concentration. Before you know it, you'll find a harpoon plunged into the heart of your robot as maniacal laughter eminates from this wicked competitor. Speak no wrong of our great nation while battling this vigilant countryman. The Patriot stands for all things that you have somehow desecrated, and it will not stop until you have been vanquished. No one is really sure whether Zombie is a real zombie, or just likes to play the part with his self-named robot. Creepy as can be, he'll make you glad you control your bot from behind a plexiglass wall. The Eastside legend has come to play. Infamous B.A.D. is known well for his rhyme, but known even better for his Robot Arena assault. Don't go trespassing in the neighborhood of Urban Menace if you don't expect a fight. Shell shocked in the battle of Goober's Cove, Sgt. Graham relives his tour of duty with every robot combat match. He built Commando to precise military standards, and would certainly have included machine guns and grenade launchers if they weren't against the rules. Floyd Bullheimer is a relentless competitor who has dominated the space combat arenas for the past six years. No one has given the air-powered ram a better name than Red Giant, Bullheimer's highly tweaked and highly respected battle machine. Fear is not known to Cyborg, who is himself only half-man, half-robot. New to the tournament as of last year, Executioner has never been defeated in a Robot Arena battle.
