The symbiote saga is far from over. A chilling and visually intense fan-made concept trailer for Venom 4: Rise of Knull (2026) has just dropped—and fans are already calling it the darkest and most ambitious chapter in the Venom franchise yet. Starring Tom Hardy once again as the tormented antihero Eddie Brock/Venom, the trailer imagines a war on a galactic scale with the arrival of the god of the symbiotes himself: Knull.
Set shortly after the events of Venom: Let There Be Carnage and the multiversal chaos hinted at in Spider-Man: No Way Home, the trailer opens with ominous shots of black tendrils spreading across distant galaxies. A mysterious voice growls: “Before light, there was me.” What follows is a haunting montage of corrupted worlds, collapsing stars, and Venom himself being haunted by terrifying visions of his origin.
Enter Knull—the primordial being who created the symbiotes and now seeks to reclaim them by force. Fan casting in the trailer imagines Cillian Murphy or Bill Skarsgård as the ancient dark god, whose powers include mind control, darkness manipulation, and commanding legions of living abyssal armor.
Hardy’s Eddie is pushed to the edge, both physically and mentally, as the bond with Venom begins to fracture under the overwhelming influence of Knull’s hive mind. The teaser shows desperate alliances forming, including a surprise appearance from a red-and-black symbiote that fans speculate could be Toxin or a re𝐛𝐨𝐫𝐧 Carnage.
The trailer blends Lovecraftian horror with superhero action—space battles, symbiote-on-symbiote combat, and mind-bending dream sequences that hint at the deeper lore of the symbiote origin myth. The final scene shows Venom growing monstrous wings, roaring into space as Knull descends through a blood-red storm.
Though purely a fan-made trailer, the excitement has been massive. Hashtags like #Venom4, #RiseOfKnull, and #TomHardyReturns are trending, with fans praising the concept’s scale, tone, and faithfulness to Marvel’s darker comic arcs (King in Black in particular).
Venom 4: Rise of Knull isn’t confirmed by Sony or Marvel—yet—but this concept proves the fan appetite for cosmic horror in the symbiote universe is stronger than ever.
The darkness is calling. And it wears a crown.
