Two years before joining the Young Masters, Big Zero met Egghead and since then they have apparently been boyfriend and girlfriend. She is a white supremacist, who started changing Egghead's parameters so that he disrespects all other races, just like her. Both she and Egghead were asked by Coat of Arms to join the Young Masters.
Big Zero was created by Paul Cornell and Mark Brooks in 2009 and first appeared in Dark Reign: Young Avengers # 1.
Powers and Abilities
Big Zero is a size changer, who is able to both shrink and enlarge herself though she has only been seen enlarging herself. She is apparently able to go up to 100ft tall, though this is unconfirmed. She also has some ability with machines, as she is able to reprogram Egghead.
