Synopsis
The issue opens with a disembodied voice talking to his daughter Katie. A symbol attached to the word balloons suggests it's Havok. He says that he and his wife are going on a potentially fatal mission. And the day that the world now celebrates was really a disaster that was their fault. (This of course is foreshadowing, and we'll learn more about this situation in future issues.)
Next we have a series of cameos as Kang rescues super-characters from various disintegrating futures:- Stryfe from 3806. The female Venom/Spider-Girl from 2033 Earth X. Dr Doom from 2099. Iron Man from 2020. Ahab from 2014 (reclaiming his servant but leaving Red Skull behind). Magistrate Braddock from 2043. A Deathlok from 2055.
Now, in the Apocalypse Twins' spaceship in the Akkaba Nebula, Rogue and Sunfire are hunting for Scarlet Witch to stop her from helping the Twins. Last issue Wolverine made Rogue swear not to kill her - there's been too much death lately. But Rogue thinks she knows what he really wants.
The Twins expect Wanda to cast a spell that will use the power of Wonder Man to Rapture all mutants away to a new world, where they'll be safe from humans forever. The Witch asks the Twins to leave her and Simon alone, because she needs absolute peace for the spell. Really she intends to bring the mutants here, to fight the Twins. The Twins agree, but only because Eimin has foreseen what will actually happen.
Rogue and Sunfire arrive in mid-spell, but have to get through Daken and Grim Reaper, 2 of the 4 resurrected Horsemen. Rogue is initially wounded by Daken's claws, and then Reaper goes after her leaving Daken to face Sunfire. But Rogue has absorbed Wolverine's powers, including his healing ability and bone claws. So she sets out to kill Reaper (again, after #5).
Meanwhile Wolverine turns up, recovering from last issue's torture by his dead son Daken. Father and son face off again, freeing Sunfire to go to stop Wanda.
Sunfire takes away the power source for the spell, Wonder Man. Rogue, still bitterly blaming Scarlet Witch for the decimation of mutantkind after House of M, runs forward. And Daken forces Logan to watch as Rogue skewers Wanda with his claws. Then Grim Reaper kills Rogue with his scythe. And Daken goads Wolverine that it's all his fault, until Logan kills him (again).
Meanwhile Wonder Man has told Sunfire that the Witch was trying to bring mutants here to oppose the Twins. Simon rushes to the side of dying Wanda. Together they finish the spell, and WM's ionic body dissipates, returning to the energy from which she restored him (in the post-Heroes Reborn Avengers). And Wanda sinks to death as she calls the mutants to her.
