After the Ultimatum Wave hits Manhattan, Jean refuses to allow Rogue to join her, as she cannot be trusted. Rogue then attacks Department H, absorbing Sasquatch's power and attacked Jubilee. It is then revealed that Vindicator is, in fact, John Wraith, whom she blames for ruining her life. She threatens him for help in killing Magneto. They travel to Montreal, where Rogue poses as a stripper to get close to Sabretooth and the Juggernaut. The Purifiers soon attack the X-Mansion and the Juggernaut dies fighting alongside Rogue. Rogue absorbs his powers just before he dies and now permanently possesses them. She then helps the X-Men in their effort to defeat Magneto and his Brotherhood. They do so, but suffer many casualties. Rogue is one of the few X-Men to survive to battle alongside Jean Grey, the Iceman, Shadowcat, Storm, and Colossus. She is last seen helping Jean Grey and the Iceman tear down the Xavier Institute and everything on the estate. They bury the remains of the deceased X-Men in its place.
