Spider-Man: No Way Home confirmed the existence of symbiotes in the Marvel Cinematic Universe with Venom leaving a part of it in this universe, but Eternals secretly set up the MCU’s first symbiote before No Way Home did. The MCU continues its expansion with its Phase 4, bringing new characters, events, and concepts to this connected universe, and the one at the core of this new era is the multiverse. Thanks to Spider-Man: No Way Home, it’s now confirmed that the previous versions of the web-slinger and the characters from Sony’s Spider-Man Universe are part of the multiverse, and the post-credits scene brought a piece of the Venom symbiote to the MCU.
Spider-Man: No Way Home picks up minutes after the end of Spider-Man: Far From Home, and sees Peter Parker (Tom Holland) asking Doctor Strange (Benedict Cumberbatch) to cast a spell that will make everyone forget he’s Spider-Man. Unfortunately, the spell doesn’t go as planned and instead the gates of the multiverse are opened, allowing villains from past Spider-Man movies (Green Goblin, Doctor Octopus, Sandman, Lizard, and Electro), as well as the previous Spider-Men, to cross over to the MCU. However, these weren’t the only characters who paid a visit to the MCU, as Eddie Brock (Tom Hardy) and Venom did so too in the post-credits scene, with Venom leaving a piece of itself in this universe – but Eternals set up the MCU’s first symbiote before Venom did that.
