During the "Avengers vs. X-Men" storyline, the Phoenix Force is split into five pieces and bonded with Cyclops, Emma Frost, Namor, Colossus and Magik (who become known as the Phoenix Five). Eventually, Cyclops and Frost come to possess the full Phoenix Force, and Professor X is instrumental in confronting them both, and dies in the ensuing battle with Cyclops. The Phoenix Force is subsequently forced to abandon Cyclops as a host by the efforts of both Hope Summers and the Scarlet Witch.
