Main event
Twelve billion years ago, an ancient race called the Viscardi were visited by a Celestial. He gifted them with a mirror known as the Black Vortex. Those who "submit" to the Black Vortex gain Celestial power, and with this immense power the Viscardi attacked each other toward extinction. There was only one survivor, Gala, and the Vortex was lost.
J'son locates the Black Vortex after visiting a Celestial graveyard. Kitty Pryde and Star-Lord decide to steal it before J'son uses it on himself and Thane. However, he uses it on his Slaughter Lords. Kitty and Star-Lord recruit the X-Men, Nova, and the Guardians of the Galaxy to prevent the Slaughter Lords from retrieving the Black Vortex. Greatly overpowered when the Slaughter Lords attack, Gamora, Beast, and Angel submit and tip the balance of the battle.[4] The team then fight among themselves, and Ronan the Accuser steals the Vortex.[5]
Gamora, Beast, and Angel are enraged and attack Hala, the Kree empire's capital planet. The team split into three groups: one battles Gamora, Beast, and Angel; the second stays on Spartax to distract the Slaughter Lords; and the third team speaks with the Kree Supreme Intelligence. The Supreme Intelligence demands that Ronan stand down until their star fleet can return, but Ronan uses the Vortex. He is successful in repelling Gamora, Beast, and Angel, but is banished by the Supreme Intelligence. The Slaughter Lords and J'son use this opportunity to sneak into Hala to steal the Vortex, and the floating fortress unleashes a massive barrage that destroys Hala. The heroes narrowly escape, and Nova acquires the Vortex from the Slaughter Lords. The Collector follows Nova to Earth and attempts to steal the Vortex, but Nova goes to Spartax and unknowingly returns it to J'son, who empowers Thane.[6] Thane then uses his super-powered "Living Death" and engulfs Spartax in amber. J'son allows the Brood to invade Spartax and use its citizens as hosts. His plan was to take out the two largest empires, Spartax and Hala, allowing the Brood to spread, then use it to take over the galaxy.[7]
Cyclops, Iceman, and Groot are captured by the Slaughter Lords but are able to escape and steal the Vortex. They give themselves cosmic powers and pass the Vortex to Captain Marvel.[8] She is confronted by a super-powered Thane and J'son and resists the temptation to use the Vortex, instead using the mirror surface to reflect Thane's Living Death blast at J'son, encasing him in amber. Gala then returns, defeats Thane, and attempts to destroy the Black Vortex before it can corrupt anyone else.[9] Captain Marvel is able to return the Vortex to the team, and they debate who should use the power one more time to save Spartax. Jean Grey offers, but everybody is worried about a repeat of the Dark Phoenix. Star-Lord contemplates but knows if he is super-powered he will waste his potential. Kitty Pryde volunteers to shoulder the burden. Gala agrees to it being used one last time.[10]
Kitty Pryde gains cosmic powers and uses her phasing ability to phase out the entire planet of Spartax from the amber, except for the Brood, which are then destroyed. The Slaughter Lords retreat afterwards. Cyclops, Iceman, Groot, and Beast return their cosmic powers, but Gamora, Angel, Kitty, and Ronan keep theirs. Star-Lord then proposes to Kitty. Gala takes away the Black Vortex. The Collector collects the amber-encased J'son. Ebony Maw then attaches himself to the cosmically powered Thane.[11]
In the aftermath, Ronan vows to rebuild the Kree Empire. Victoria, Star-Lord's half-sister, meets with the Collector. She strikes a deal with him in order to secure J'son's body, but secretly steals the last remaining seed of the Kree Supreme Intelligence.[12]
