It was revealed by the
Sugar Man, that he and Rastus where from the
Age of Apocalypse, a place where
mutants thrived and the chosen ruled the world. Rastus was a large two headed monster that was incredibly strong and really fast for his size. He lived in the catacombs underneath the island nation of
Genosha. He was accidentally discovered by the
Dark Beast, who was assisting a group of
Magistrates in locating a hidden supply vault. All of the Magistrates were slain, although, the Dark Beast was able to escape and informed the
Morlock,
Callisto of the massacre that had taken place. Callisto persuaded
Wicked to use her spirit controlling ability to explore the catacombs underneath the island. This search resulted in the spirits being attacked and both Callisto and Wicked suffering the pain through empathic backlash. Callisto and
Omega Sentinel teamed up and went into the tunnels together, leading to a violent underground battle with the Sugar Man and the two headed monster Rastus. Callisto killed both men, after having lost her left arms.
