Billy Kaplan was the eldest of three sons born to Reform Jews Jeff Kaplan, a cardiologist, and Rebecca Kaplan, a psychologist. Billy had trouble with bullies in school due to his sexuality and fanboyness. Once while sitting in front of Avengers Mansion, he briefly met the Scarlet Witch, his favorite Avenger. She gave him some words of encouragement and told him that he "could take care of himself". Billy took her advice and stood up to his bully, John Kesler. Unfortunately, Billy's electrokinetic powers emerged for the first time and nearly killed Kesler.
