Venom: The Last Dance introduced the next major Marvel villain in the form of Knull, and I am praying Marvel does not repeat its Thanos recasting. By the time of Venom: The Last Dance‘s ending, it was clear that Knull was being positioned as a major villain going forward in the Sony Spider-Man Universe. The many symbiotes of Venom 3‘s story were left facing off against the Xenophages in the film’s ending, creatures sent by Knull to retrieve something called The Codex that would free him from his prison.
