Knull

An ancient god born in the void before creation itself, Knull was stirred to rage when the Celestials' light invaded his primordial darkness. He forged All-Black the Necrosword from that darkness and eventually created the symbiote race as living weapons to spread his dominion across the cosmos.

Few villains in Marvel's Modern Age have arrived with the kind of mythic, bone-deep menace that Knull brought when he first slithered into the pages of Venom #3 in 2018. A figure of cosmic darkness whose presence reverberates through some of Marvel's biggest names — Venom, Spider-Man, Eddie Brock, Captain America, and Peter Parker have all shared the page with this ancient threat — Knull quickly grew from a shadowy revelation into a full-blown event-level force, anchoring not just Venom but his own series and the sprawling King in Black crossover. With 67 catalog appearances, at least one key collector issue to his name, and a publishing footprint stretching well into the 2020s, he's proof that the Modern Age can still conjure a villain who feels genuinely primordial and world-shaking.
