They fought off the Annihilation Wave. They freed Hala from Ultron and the Phalanx. But then, the war between the Shi’ar Empire and the Kree/Inhuman alliance tore a hole in the fabric of space and time – the Fault – which threatens to spew forth the undying invaders from the Cancerverse. Can the Guardians of the Galaxy, Nova, the Shi’ar Imperial Guard and the Inhumans put their differences aside to save the universe from the Many-Angled Ones and their Revengers? And could Thanos hold the key to victory?

But a mindless Thanos has been unleashed and Martyr (Phyla-Vell) was the first to die at his hands. He’s gone on to kill the billions of followers of the Universal Church of Truth on this world. Star-Lord uses his Cosmic Cube’s one last shot to floor this indestructible incarnation of Thanos, releasing his mind and allowing Moondragon, Cosmo & Mantis to mentally lock him down.

✔ | The Thanos Imperative: Ignition #1 When Thanos died at Drax’s hands, Adam Warlock put his body in a cocoon that was found by the Universal Church of Truth. Now he’s alive again, but he’s not happy about it. Gladiator, the Imperial Guard, King Blastaar’s forces, the Spartoi and the Inhumans head to the Fault to combat the Universal Church of Truth’s Templeships. Dark Quasar gets to the Templeships before Nova or the real Quasar can stop him. Adam Magus summons converted worlds to the Fault and detonates them to open the Fault even further. Thanos breaks free of his cell on Knowhere. Lord Mar-Vell of the Cancerverse emerges, kills Magus for failing to despatch Death’s new avatar and orders Dark Quasar to assemble the Revengers… |
✔ | The Thanos Imperative #1 The Fault is now wide open and the horrifying creatures from the other side spill into Reality-616, ripping into the Kree, Shi’ar, Inhuman and ships. They’ve entered a reality where death still exists and their masters, the Many-Angled Ones, can grow to fill it with their undying forms. The Cancerverse’s Revengers – dark, undying Avengers – attack the Nova Corps’ ship and take Namorita. The Guardians of the Galaxy free Thanos and a select group join him on a mission into the Cancerverse where Thanos collapses and a dark version of the Defenders loom over them… |
✔ | The Thanos Imperative #2 The Silver Surfer joins the fight, bringing Galactus, Tenebrous, Aegis & the Celestials with him. Something called the Galactus Engine charges out of the Fault and heads directly for them. As another chronal anomaly, Major Victory is taken captive by the Revengers and held in Thanos’ old ship, Sanctuary, with Namorita and others. In the Fault, the Guardians quickly shut down the Defenders of the Realm, but they’re unable to die and get right back up. Thanos rises and proves capable of killing them… |
✔ | The Thanos Imperative #3 Aegis is killed but passes her knowledge of their foes to Nova, informing him of Lord Mar-Vell’s whereabouts. Nova recruits Beta Ray Bill, Ronan the Accuser, Gladiator, Quasar and the Silver Surfer into his strike team. In the Fault, Thanos and the Guardians meet the Machine Resistance – the Vision, Jocasta, Machine Man & other robotic heroes of Earth-10011 – and are taken to their hidden base on Titan. They explain that the Mar-Vell of their universe accepted a pact with the Many-Angled Ones to save his own life and perform the Necropsy to end death. Only Thanos can undo it. Before they can head to the Sanctuary of this reality, Drax – overloaded in his role as an avatar of life by the Cancerverse – is compelled to attach an anti-matter charge to Thanos which disintegrates him… |

✔ | The Thanos Imperative #4 Lord Mar-Vell studies the anomalous Namorita and others as part of his search for Death’s avatar when Nova’s squad attacks. Tearing through the Cancerverse’s Ex-Men, Spider-Man and Revengers, the team reach Lord Mar-Vell. But Nova finds himself completely outmatched. In the Fault, Death’s rejection of Thanos since his rebirth has left him unable to die. He painfully reconstitutes from scratch and obliterates Drax. Lord Mar-Vell senses this from our universe and teleports himself and the remaining Revengers to Titan in the Cancerverse, destroying Sanctuary as he goes… |
✔ | The Thanos Imperative #5 When she sees the dying Vision of her universe , the Cancerverse’s Scarlet Witch reveals she’s been working with the Machine Resistance against her fellow Revengers all along. In Reality-616, Quasar’s quantum shields saved Nova’s squad and the freed prisoners from certain death. The Galactus Engine is tearing through the allied forces and abstract beings. Nova breaks rank and heads into the Fault to find the Guardians, empowering Quasar with enough Nova Force to take over the Corps. But Lord Mar-Vell and the Revengers catch up with Thanos & the Guardians first, before they can reverse the Necropsy. In an unexpected move, Thanos bows to Lord Mar-Vell and asks for the release of death… |
✔ | The Thanos Imperative #6 Nova arrives and frees the captured Guardians, but not before Lord Mar-Vell summons the Many-Angled Ones to perform the Necropsy on Thanos to end his life. Thanos’ imminent demise allows Death herself into the Cancerverse. She takes Lord Mar-Vell’s life which restores death to the entire reality, instantly weakening the Many-Angled Ones and destroying their warped armies on both sides of the Fault as it collapses. Death rejects Thanos again, enraging him enough to want to return and wipe out all life in the universe. Star-Lord orders the Guardians to return home, but remains behind with Nova to make sure Thanos remains trapped in the Cancerverse when it dies. Three days later, a memorial is held for Star-Lord, Nova, Drax, Martyr, Adam Warlock and all who died. The Xandarian Worldmind has recalled the Nova Force and shut down. The Fault has sealed and the Cancerverse has been annihilated. |
✔ | The Thanos Imperative: Devastation #1 One week later Blastaar’s forces assault Hala, with no Nova Corps or Guardians of the Galaxy to stop them. But, over the previous few days, Cosmo followed Star-Lord’s final wish and recruited Beta Ray Bill, Gladiator, Quasar, Ronan the Accuser and the Silver Surfer to guard the galaxy as the Annihilators to form when needed.
