You are not really told much about Gerald and his past. Gerald has the power of invisibilittie and can fly. Gerald doesn't use his powers that much put he does when he has to. Gerald does not have an official super hero name except in Gerald's first epsiode he is named as the Invisible Villain but that was before Bob knew it was his father. Gerald used to be a super hero when he was 22 he also met his wife Helen when he was stopping a villain.
