|First Appearance||Too Hot to Handle|
Hammer was one of the safe crackers that tried to open P'andor's armor.
He is tall, bald, and has a black mustache. He resembles a circus muscleman, and he uses a large sledge hammer as a weapon.
Like Surgeon and Buzz, he tried and failed to open P'andor's armor, becoming very fatigued after numerous attempts to open the armor. When Kevin refused to open P'ander's armor, Hammer managed to knock him out with his own piece of Taydenite.
P'andor then recruited him, Surgeon and Buzz to work for him as he attempted to use the Taydenite to break free. After they tricked Kevin into freeing P'andor, Hammer and the others were blasted by their former leader, who no longer needed them.
