However, unlike Spider-Man 3, it’s important that Venom offer at least a little information about where the symbiote came from and why it came to our world.
While it’s impossible to have Spider-Man bring back the symbiote from a strange planet, Venom could follow in Spider-Man 3’s footsteps by having the symbiote crash-land on Earth, and from there, it finds its way to Eddie Brock.
In the Ultimate Marvel continuity, the symbiote was artificially created by Edward Brock Sr. and Richard Parker as a way to cure cancer.
Should a sequel be ordered, its background can be expanded upon, like how it’s a member of the species known as the Klyntar.
