While his past before the NULL project is largely unknown, it's stated that he had a normal upbringing until his involvement with the program. He was selected as a child to be a member of the Gamma NULL category, the most dangerous type of soldier produced by the program, because of his aggression and mental problems. Zero is a NULL who served in the Cromag War as an ally to New Mecca alongside another NULL, Fifteen.
