Nicole Callahan is the daughter of Stephen Callahan, a former member of Team 7. Team 7's superiors, the intelligence agency International Operations exposed the team to the Gen-Factor, a substance that endowed the team with superhuman powers. The survivors from this experiment were codenamed Gen 12. I.O. hoped to use them as weapons, but Team 7 turned out to have a will of their own. A couple of years later, I.O. decided that Team 7's children could have inherited their fathers' powers and if they could raise them from childhood, they could ensure their obedience.
