Is This How Marvel Plan To Introduce Symbiotes To The MCU?
1. A Threat After Thanos
This new link between the symbiotes, the Guardians and now Asgard is going to take months to unpack, but it's a premise with undoubted promise. A Guardians and Thor team-up film could easily work wonders with the symbiotes as its focus, but even without a team up, Marvel could seed a coming together in each series' solo features as well.
Further still, if it turns out that Sony's Venom movie isn't connected to the MCU, then it allows them to offer their own take on the Symbiotes. Even if it does, a quick retcon that establishes that they're alien in origin would be easy enough to convey, and would provide a suitable connection between three of the franchise's principle series (those being Thor, Guardians and Spider-Man).
And though countless other villains have been mooted to take a starring role after Thanos, including the likes of Annihilus and Galactus, this most recent addition to the Marvel Universe possesses boundless onscreen potential. Have Knull be the focal point of a future phase, introducing the symbiotes in each solo film, and there's no doubt he could fit the Thanos-style role currently occupied by Josh Brolin somewhere down the line.
