In the final issue, the X-Men and the Avengers battle the Dark Phoenix, but they lose ground swiftly as the Dark Phoenix starts to burn the world. As a last resort, Captain America sends in Hope and Scarlet Witch, who together manage to take down the Dark Phoenix, while Jean Grey appears within Cyclops' mind and convinces him to let go of the Phoenix Force. The Phoenix escapes Cyclops' body and enters Hope Summers'. Together, Hope and the Scarlet Witch wish away the Phoenix Force and the damage it caused, in the process activating the X-gene that allowed the creation of new mutants around the world.
