While playing football in the park, Cyborg suddenly shuts down. After rebooting, he tells the other Titans that his batteries are dying and requires recharging, but doesn’t get the chance, because the nefarious Mumbo is causing havoc in Jump City. While facing him down, Cyborg’s emergency batteries fall off, and his inert body falls down into the underground depths of a junkyard. The Titans believe Mumbo has kidnapped him, but he has instead been found by a strange machine called Fixit, who doesn’t share Cyborg’s views of humanity. Instead, he believes it to be a flawed part of Cyborg’s biology – one that he intends to correct, with or without Cyborg’s consent.
