Ultimate X-Men Vol. 2: Return To Weapon X
Mark Millar (Writer); Adam Kubert, Tom Raney, and Tom Derenick (Artists)
Xavier's School... under siege! The X-Men... abducted! Now pawns of the mysterious Weapon X program, the mutant heroes' only hope lies with the one team member to evade capture: the enigmatic, unproven Wolverine! Can Logan go it alone against the shadow-ops organization that transformed him into one of the world's most lethal killing machines? To succeed, he must survive an adrenaline-charged, adamantium-laced brawl with the savage Sabretooth - a predator every bit his equal!
