Synopsis
After the abduction of the baby Apocalypse Twins in #5, Genocide son of Apocalypse wants to be anointed as successor to his father. He and the 3 existing Horsemen of Apocalypse (Death, Famine and Pestilence) take their Celestial spaceship to the Starcore Station, which is capable of broadcasting a message anywhere in the universe or beyond. A Celestial answers the call, and gives Genocide a Death Seed to empower him to continue Apocalypse's work pruning the genetic tree to produce the 'best' mutants.
Genocide is awaiting the gift of armour like Apocalypse's too, when the grown-up Apocalypse Twins Uriel and Eimin appear, Uriel brandishing the axe Jarnbjorn from last issue. And he uses the Asgardian weapon, empowered by an Odin-spell, to cleave the Celestial's armour. And for the 1st time in universal history a Celestial is killed.
Eimin rescues her mother Pestilence. Famine and War try to prevent her, but Eimin emits acid that burns through time and her enemies are trapped in an eternity of pain. Uriel offers to let Genocide serve him, but Genocide's response is a plasma blast which Uriel the chronomancer diverts to dissipate in a pocket of accelerated time. The Twins leave (with Pestilence?).
After Rogue accidentally killed Grim Reaper in #5, Havok is having a meeting in Avengers mansion with SHIELD Agents Maria Hill and Nick Fury Jr. They admit that Rogue killed Reaper in self-(or at least team-)defense. She won't face charges, and they'll do what they can to calm things down. But it has helped fuel the anti-mutant feelings begun by Red Skull (with Prof X's brain) and his S-Men in the 1st arc of this series.
Havok takes their message to a team meeting (Captain America, Sunfire and Wonder Man aren't there). They need to go after Skull. But they also need to keep Rogue out of the public eye for a while. Rogue never really wanted to be on the team, and she'll quit rather than sit idle. Thor reminds Havok of his declaration in #5 that no Avengers (Rogue and Scarlet Witch in particular) should have to hide. The argument splits along Avengers/X-Men lines, with Wasp supporting Scarlet Witch as a long-time Avenger. Havok ends the discussion by giving Rogue the job of investigating Magneto (ie presumably Cyclops' new team in Uncanny X-Men). Which Rogue isn't too happy about.
Then we have a sopa-opera interlude where Scarlet Witch consoles Wonder Man about the death of his brother Grim Reaper. Simon's also full of angst about the fact that Wanda brought him back from (sort-of) death, and he shouldn't really be alive. *He* says he came back from the dead for love of her. But *she* says she only loves him like a brother. (Despite the fact that they *have* been lovers.)
Meanwhile Wasp shows Havok the clothes she's designed based on mutant superhero costumes, to get the young to like them. And also it will make enough money to fund the team. (So maybe Janet *hasn't* got her fortune back, as I wondered about last time.) Jan and Alex compare recent problems in their lives. Then Jan hits on him, and Alex's attempt to turn her down graciously is interrupted by an Avengers alert.
Cap and Sunfire have been with Commander Abigail Brand on S.W.O.R.D.'s satellite The Peak. They viewed the destruction of the Celestial, and now see the Apocalypse ship approaching them. They called the alert, and show the assembled team the video of the death of the Celestial. Both Uriel and the axe Jarnbjorn are unknows to Avengers records. But Thor and Wolverine both recognise something. And Thor rushes off.
Up in space the Celestial ship is on a collision course with The Peak. Agent Brand orders evacuation. Sunfire shoves Cap into the last available escape pod, and stays to face the collison. The impact sends a large chunk of the satellite falling towards Rio de Janeiro. Where Thor is ready to stop it, to make up for his mistake last issue of turning Jarnbjorn into such a deadly weapon.
