In Absolute Carnage #3, the titular villain surprised everyone when he infiltrated the Maker's compound and attacked every hero hiding inside. Ever since the start of the miniseries, the Maker, a villainous Mister Fantastic from another universe has been working with Eddie Brock to help him save everyone who has ever bonded with a symbiote before. These people who were once hosts now have a piece of Klyntar left behind in them, a codex that Carnage is desperately after. Thankfully, the Maker has created a machine that can safely remove the codex from someone and destroy it.
But while certain Avengers were all going through treatment to remove the codexes, Carnage attacked. This prompted the Venom symbiote to leave Eddie and bond with someone else -- someone stronger, who is willing to fight to the death: the Immortal Hulk.
Now, in Absolute Carnage #4, Carnage not only defeats the Hulk, but steals the Venom symbiote. With hope all but lost, Eddie steps up and becomes a new kind of Venom.
As Carnage engages in battle with the Venom-powered Hulk, Eddie Brock continues to prove himself a hero, even without his symbiote. He grabs Captain America's shield and rushes in to prevent Carnage and his army of drones from killing the Avengers who are still connected to the Maker's machine. However, things take a turn when Cletus Kasady defeats the Hulk and bonds with the Venom symbiote, which he wears on top of his Carnage symbiote. Eventually, enough time passes for the Avengers to wake up, and they too join the fight now that their codexes have been safely removed.
That's when Miles Morales reveals that the Maker was lying: his machine doesn't destroy the codexes -- it stores and collects them. While it's not clear what the Maker was planning to do, that doesn't matter for the time being. Eddie breaks into the machine, and bonds with all of the codexes of the Avengers. They connect with his own, transforming him into a Venom/Avenger hybrid. The codexes appear to store the attributes of their hosts, which means that Eddie now also has a part of Captain America, Wolverine, Hawkeye and the Thing in him.
With the codexes, Eddie has access to Captain America's battle strategies; Wolverine's rage; Hawkeye's precision; and the Thing's strength -- all of which are now mixed in with Eddie's symbiote. He's stronger now and more powerful than ever. He's essentially just been transformed into a one-man army of Avengers.
While the combined version of Carnage and Venom makes Cletus Kasady more dangerous than ever, Eddie has leveled the playing field with his one-man Marvel Team-Up. Now, the only question remaining is whether or not Eddie's new powers will be enough to bring Absolute Carnage to an end.
