When the Avengers manage to defeat Namor with a mass assault on him during an attack on Wakanda, his portion of the Phoenix Force becomes divided between the other four members of the "Phoenix Five," making it harder to defeat them. Spider-Man then baits Colossus and Magik into taking each other out by playing off of their fears when fighting them in a volcano, as they begin to argue about the other's recent actions, forcing their portions of the Phoenix to be divided between Emma and Cyclops. When Cyclops invades the mystical city of K'un Lun, Lei Kung defends the city on the back of the immortal dragon Shou-Lao the Undying, revealing it had defeated the Phoenix in a past incarnation. While Cyclops defeats the dragon, Hope is able to absorb its power and defeat Cyclops who then goes to seek the other remaining portion of the Phoenix Force possessed by Emma Frost. Emma Frost had been using the Phoenix Force to control all of Utopia, read the thoughts of everyone on the planet, take vengeance on anyone who had ever harmed a mutant and dismantle all Sentinels. In a clash against the Avengers and the X-Men with both remaining Phoenix hosts increasingly hostile towards the other, Cyclops defeats Emma and elevates to the level of Dark Phoenix, killing Professor X in the process.
