Ever wonder what being a giant battery is like? Me neither.
Zack's personality is somewhat dull. He has never had a family, going from one orphanage to the next. The closest thing he had to family was a two year stint living with the Brotherhood. He is social unadept and doesn't know what being a friend means. There is a kind heart buried somewhere, waiting to be set free. He could prove a good and loyal friend, but has never had an oppurtunity for such connections. His only emotion outlet has been music.
Zack does not remember where he was born, or even having a family. The earliest memories he has are of orphanages, and accidents involving his powers. When he turned eleven, he started finding ways to escape said places, and live on the streets, but he always ended up back in them. He followed this cyle for three years. Escaping, returning, a short stint in a foster home. Until he was fourteen almost fifteen. He escaped for the last time, and thru a turn of events, ran into Magneto, who was impressed by his power. Magneto tricked him with promises of a home, and the oppurtunity to learn to control his powers. He took the offer, and for the next two years, lived with the Brotherhood. He didn't receive some training, but mostly, aided Magneto in several of his illegal undertakings. His abilities were put to use by Magneto, who tricked him into thinking it was all for the good of human and mutant kind alike. Zack finally realized what was truly going on, and escaped the clutches of Magneto, after a trying struggle with Sabertooth. He now finds himself at the academy, after being found by Logan.
