Emma Frost is appointed by Norman Osborn to lead his new team of "Dark X-Men". Each member is hand-picked by Norman but Emma has Namor added to the team for her own reasons. The team debuts to the public as the official "X-Men" maintaining high public approval through Osborn's careful media strategy. They oust the original X-Men, portraying them as a dangerous militia. Meanwhile, Emma discovers that Osborn is working with the Dark Beast, torturing apprehended mutants and feeding their powers into a machine that empowers Weapon Omega. Cyclops sends X-Force on a strategic evacuation of the mutant prisoners, resulting in a planned confrontation with the Dark X-Men. As the teams prepare to face off, Emma then reveals her role as a double agent, defeating the Dark X-Men with Namor's assistance. She extends an invitation to Cloak and Dagger to join the true X-Men as they teleport to the newly created island base Utopia.
