In Spider-Man 4: King In Black (2025), the full teaser trailer gives fans a dark and intense glimpse into Spider-Man’s next major challenge as he faces the terrifying threat of Knull, the God of Symbiotes. The trailer opens with Peter Parker (Tom Holland) reflecting on the aftermath of recent battles, his voice-over expressing doubt about his ability to keep protecting those he loves. We see him juggling his duties as Spider-Man and trying to reconnect with MJ (Zendaya) after the events of Spider-Man: No Way Home.
The scene quickly shifts to eerie footage of a cosmic force descending upon New York City. Symbiote-infected creatures begin to spread chaos, and we learn that Knull (played by a mysterious villain) has arrived on Earth, bringing with him the full power of the symbiotes, threatening to engulf the entire planet in darkness. The symbiotes, led by Knull, start attacking civilians and heroes alike, turning them into monstrous versions of themselves.
Peter suits up, but it’s clear from the start that he’s outmatched. The trailer introduces Eddie Brock (Tom Hardy) as Venom, who reluctantly teams up with Spider-Man, knowing that their combined strength may be the only way to fight back against Knull’s invasion. The tension between Venom and Spider-Man remains palpable, but they form a fragile alliance to face a threat that neither of them can handle alone.
As the action builds, the teaser reveals jaw-dropping visuals of symbiotes covering entire skyscrapers and consuming the city in black ooze. Spider-Man battles these dark creatures across the rooftops, struggling to stay ahead of the wave of destruction. The trailer hints at major cameos from other Marvel heroes, with brief flashes of Doctor Strange (Benedict Cumberbatch) and Black Cat (rumored to be played by Anya Taylor-Joy) offering their assistance in the fight against Knull.
The final moments of the teaser show Spider-Man in his darkest moment, symbiote tendrils creeping closer, as Knull taunts him: “Are you ready to bow before your true king?” The screen cuts to black, leaving fans eagerly awaiting what comes next.
