The G.L.M., Galvanic Lifter Machine, aka GoLeM, was a construction robot. GoLeM was remotely controlled by halo-like headband.
Having been bullied by Nelson Nash too many times, Willie Watt takes his father's advice to "hit 'em where it hurts" and steals the GoLeM to interrupt Nelson and Blade's date by crushing Nelson's car. Batman electrifies it, causing its circuits to fry and a feedback loop to the control headband. The GoLeM is soon impounded.
Willie soon finds out that he has a technopathic link to the GoLeM. He tests it out on a gang of Jokerz, scaring them away. He soon uses it to get even greater revenge on Nelson when he is pushed into the water. He then turns his attention to his father, who he hated much more. Batman destroys it with a rocket ride. Willie cried over his only "friend". He later finds out in juvenile hall that he had telekinetic powers. He had called them a gift from the GoLeM.
