Spoilers for Venom: The End by Adam Warren, Jeff "Chamba" Cruz, and Rahzzah below
The Venom symbiote is nothing if not a survivor. Since the character was first introduced back in Spider-Man #299, Venom has bonded with a growing number of Marvel superhero hosts. And while its biological partners have come and gone, the symbiote has adapted to live another day. Which raises the question: how does the Venom symbiote actually meet its end? Well, it's complicated.
Venom: The End is the latest in a series of one-shots from Marvel Comics telling 'the final story' for different characters. Where some ends are destined to arrive in just years or decades, Venom's final story spans trillions of years, and involves some of the most insane plots and storytelling that the character's ever been a part of. Yet somehow, it tells a wild, perfectly fitting end for the symbiote.
The one-shot tells the final fate of the Venom symbiote, taking place over multiple lifetimes through Marvel's future. Eddie Brock is the last living human, as a husk who's been kept alive within the symbiote via "cellular bioscaffolding." Venom has replaced Eddie's neurons one-by-one, and eventually sees his former host crumble in his hands. Leaving the symbiote all alone, for the first time since meeting Eddie... and finally ready to face the Artificial Superintelligence arms race that has caused an A.I. takeover of the universe.
After failing to unify the remaining symbiotes in one last defense for the fate of biolife, as opposed to A.I., the Venom symbiote uses the contained codex of Multiple Man Jamie Maddrox to create his own army of hosts. He keeps experimenting with a slew of other mutants as new hosts, eventually using Quicksilver's codex to distort space-time and bond with literally everything that's ever lived. Venom uses the multi-dimensional network of codices contained within his form (as the last of the symbiote hive mind) to respawn all of the biolife into a new Venomverse - while bringing all of his former hosts back into their proper time streams inside the new universe.
Venom quite literally weaves himself into a new universe, where biolife can begin again -- essentially making him responsible for bringing biolife back from extinction, and preserving their symbiote-free future. It's an incredible sacrifice, and one that shows Venom is more than just a mysterious alien symbiote - he cares about humanity.
Venom: The End gives the antihero a heroic sendoff, in the form of an outrageously complicated story told over trillions of years, surprisingly bringing his journey full circle. Who knew Venom would be the force that brought humanity back from extinction? It's a nice twist to give Venom a proper, albeit bananas, end. Even if Eddie wasn't there to see it...
