Beef was the super-strong member of the Hellions, a team of adolescent mutants formed by the Hellfire Club's then-White Queen, Emma Frost, joining the team shortly before the Hellions' clash with the New Warriors.
Beef was among those Hellions slain by the time-travelling Trevor Fitzroy during the villain's assault on the Hellfire Club. Recently, Beef was revived with an alien techno organic virus.
