I never followed the whole Xorn thing, someone want to explain it? I also find it funny that Marvel is still photoshopping/borrowing images in media for their artwork.
SPOILERS, YO Xorn was a new mutant character introduced in Grant Morrison's run who was a pacifist with a star inside his head... Or so we thought initially. It turned out that it was actually Magneto. Magneto then got addicted to a drug called Kick (which boosts up mutant abilities and turned out to be a sentient mold named Sublime), when on a rampage, killed Jean Grey, and was beheaded by Wolverine all in the second to last storyline of Morrison's run. Then after Morrison left, X-editorial decided to go and make some changes, such as having Chris Claremont bring back Magneto in the new EXCALIBUR series just a few months after Morrison's series tenure completed (Xavier shows up in the ruins of Genosha and finds Magneto alive and well in there, who points out that it couldn't have been him who rampaged through New York.) and having Xorn be an ACTUAL character (as opposed to being Magento's charade), so the X-Men find Xorn in a prison, who asks what happened to his twin brother. And so it turns out that the Magneto who went on a rampage is an impersonator who was Xorn's twin brother possessed by the sentient mold Sublime. or something.
