During an attack on the institute, Colossus engages Sebastian Shaw, although "Shaw" turned out to be an illusory attack by Cassandra Nova. It was revealed that Colossus is the mutant destined to destroy Breakworld according to the Breakworld's precogs. However, on a mission to the Breakworld, the X-Men discover that this was not an actual prophecy but an elaborate scheme created by Aghanne, the insane leader of a Breakworld reform cult, intended to bring about that world's destruction. Colossus is chosen for the prophecy as his unique organic steel form would allow him to destroy the planet's power source, initiating a chain reaction that would destroy the entire world. Realizing this, Colossus refuses to kill the planet although he does threaten to seize power and rule it if the Breakworld destroys the Earth as planned.
