New Mutants #24
'AGE OF X' CONCLUSION!
This is it. As the psychic barricades protecting Fortress X crumble and the human militias flock to exterminate all the mutants within, mutantkind makes its last stand...against the anti-mutant forces who would see them wiped out, but also against the one responsible for their plight in the first place. And when the dust settles? No one will be left unscathed.
