Several months after the events of The Fly, Veronica Quaife gives birth to a larval sac and dies. The sac splits open to reveal a seemingly normal baby boy. Anton Bartok, the owner of the company that financed Seth Brundle's teleportation experiments, adopts the child and names him Martin. Martin grows up in a clinical environment. His physical and mental maturity is highly accelerated, and he possesses a genius-level intellect, incredible reflexes, and no need for sleep. He knows he is aging faster than a normal human, but is unaware of the true cause, having been told his father died from the same rapid aging disease.
