The X-Men are losing the battle against the Nimrods and Cyclops knows it. Desperate times call for desperate measures and no measure is more desperate than enlisting a mutant with multiple personalities, each possessing its own power. That's right, Legion is let out of prison to fight on the X-Men's side.
Professor Xavier enters David Haller/Legion's mind to enlist him and his multiple personalities to battle the Nimrod invasion of Utopia. As Cyclops realizes that the situation is dire he turns to all mutants on the island and issues a statement, "fight or die".
Rogue has been left in charge of Hope. Rogue is supposed to keep Hope safe from the Nimrods and take her into hiding. Instead, Hope decides that if she is to be the mutant messiah then she will fight.
All over the island Nimrods are arriving from the future in waves every five minutes. In the tunnels below Utopia, Husk, Avalanche, Sunspot and Boom Boom are attempting to keep the Nimrods at bay. As it takes all of their combined strength to stop one, more teleport in. On the bridge into San Francisco Colossus, Namor, Magma, Dust and Rockslide are trying to keep the Nimrods from advancing. Colossus is overwhelmed by the Nimrods and they manage to compensate for his strength and break his arm.
Meanwhile, the X-force unit (Wolverine, Domino, X-23, Cypher, Angel and Cable) sent into the future begin their assault on the Master Mold facility that is sending the Nimrods into the past. Cypher is able to stop assault machines by speaking in their language and the team advances into the facility.
Back on the bridge Colossus is about the be taken down by the Nimrods when they sense a much greater threat. An omega level mutant. Legion begins his assault on the Nimrods with personality 115 which seems to have a destructive sonic power. As the Nimrods begin to adapt to this power Legion switches to personality 762, a pirate with the ability to belch what seems to be an acidic compound. Just at that moment Cyclops arrives with Iceman, Psylocke, Surge, Gentle, Storm and Armor.
Back to the future, the X-force team has successfully infiltrated the Sentinel facility and realizes there are two Master Molds. One creating the Nimrods that are attacking Utopia and one that is aggressive in nature.
Back on Utopia a small contingent of mutants consisting of Litterbug, Scalphunter, Random and the Morlock Sack have decided to fight the Nimrods. Toad is tagging along and attempting to convince them to stay on the island as Cyclops' team is luring them away. As he says this to Sack, Toad's finger is disintegrated by a beam of energy which also takes of Sack's head.
The scene ends in the infirmary where Beast is treating Hellion and the Nimrods are beginning to get inside. Magneto rises from his bed and tells Beast to tend to the injured while he fights the Nimrods.
