Frenzy's history is presumably similar to their Earth-616 counterpart's. She was a member of Magneto's Mutant Force, a team of mutants dedicated to aiding mutants from human oppression. One day, she and the Mutant Force busted free Emma Frost so she could use her telepathy to help free the psyche of Charles Xavier from Magneto's mind. While Emma Frost aided Magneto, Frenzy and the Mutant Force fought off the Squadron Supreme who had tracked Mutant Force to their hideout on Island M, which Mutant Force struggled to fend off. Things looked hopeless until Cassandra Nova took over Magneto's body and banished the Squadron Supreme from Island M.
