Batman Beyond - Season 1 Episode 4 -

Willie Watt, a nebbishy student at Terry's high school, is pushed around by everyone -- including his construction-worker dad, who insists that he needs to toughen up. Aching for revenge against Nelson, the jock that torments him, Willie steals a remote-controlled heavy-lifting robot (or "golem"), and rampages through Gotham. Batman stops the Golem quickly, but as a result of the fight he gains the power to control the golem mentally -- much to Nelson's dismay.
