New X-Men #36

"MERCURY RISING" The conclusion! X-23 and Hellion have stormed the Facility to rescue Mercury. And as if Kimura and a hundred Facility agents wasn't bad enough, something is roaming the halls of the Facility... something designed to feed on mutants. Predator X is on the loose, and nothing will ever be the same for the New X-Men! Part 4 (of 4)!
