Malcolm Gregory "Greg" Murphy, who worked under the codename Man-Eater, is human and tiger merged into one body and mind. An unwilling subject in genetics experiments performed by a splinter cell of Hydra, Malcolm was physically combined with a tiger, creating a hybrid man-tiger with the memories and instincts of both. He was freed from the experimentation by the hero Battlestar when he was working for Silver Sable's mercenary team called the Wild Pack.
Man-Eater later became a member of Silver Sable's Intruders. The Intruders roster included Fin, Paladin, Lightbright, and the team leader was Sandman. This team served alongside the Wild Pack.
