Phantazia was recruited by Toad into his lineup of the Brotherhood of Mutants. She was one of the more powerful members of the group, possessing a mutant ability that allowed her to manipulate and disrupt not only the electronic systems and weaponry of her opponents, but their physical senses and superhuman powers as well. Her first mission with the Brotherhood led her to battle the mutant strike force called X-Force. There, she easily located the team's hidden bunker, shut off Cable's weaponry, and disrupted Cannonball's blast field, allowing Sauron to stab him in the chest.
