When Wolverine faces a problem of the villainous kind, there's a good chance he'll use his Adamantium claws to whip up a lethal solution to it. What happens, though, when he faces an opponent who becomes a much bigger problem if he's killed? Enter: Contagion, a bold new addition to Wolverine's rogues' gallery. But first, Logan must contend with Contagion's defenders, the aptly named crew known as the Unkillables.
