Spoilers: The main cast of “Uncanny X-Men” all take the month off as the teen Jean Grey from “Extraordinary” makes a guest starring turn, along with the Stepford Cuckoos. The issue focuses on the Jean scene from “IvX” #1, focusing on Jean and the Cuckoos’ combined attempt to keep Karnak trapped in his own mind. Things have progressed from what we’ve seen before; Karnak is now running around in a mental prison set up by the telepaths to look like New Attilan. Psylocke doesn't appear in this issue, but is among the X-Men projected into Karkak's mind by the mutant telepaths.
Meanwhile, Fantomex struck a deal with one of Cuckoos, Irma, to allow him access to Karnak’s problem-solving skills. Irma would act as the bridge between Fantomex and Karnak, feeding altered analogues of the real problems Fantomex encounters in the World into Karnak’s vision. Then, as Karnak solves the similar problems in his trance, Fantomex knows what to do in the World. This side mission is of importance to Fantomex because he has been in control of the World for a while now, and members of the nefarious Someday Corporation infiltrated the World and stole parts of its tech. Fantomex uses Karnak’s abilities to make his way to where the Someday Corporation broke in. There, he finds the device they used to hack into the World’s systems — a slug-like device. He then places his psi-shielding plates back in his mask, locking Irma out of his mind. Panicked, Irma tells the others of her secret mission with Fantomex — and they aren’t too pleased. Fantomex continues on his quest, completely moving on from the matters of Inhumans and X-Men. “Let them have their war. I’m done with all that,” he says. Fantomex removed Someday’s influence from the World’s system — and filled the void with his own id, ego and super-ego. Calling it the “God-King Virus,” Fantomex prepares himself for a massive transformation — one that he says will render him unrecognizable. “I will become the world,” he says at the end of the issue, teasing a potentially major shift in who — and what — Fantomex is moving forward.
