Viper is the enemy of Spider-Man (3029). He is the descendent of Venom. His name is Nate Brock. Jacob Parker and Nate always fought because of the rivalry between their ancestors. Viper has a symbiote ribcage so he has never broken his ribs. Viper is a very powerful person, but he has anger issues that his parents try to get rid of, but they're not successful.
In my lifetime, lots of people like Marvel, I being one of them. So I ended up making a symbiote. I and my friends make symbiotes a lot, and one of us made Viper. We made him to be the descendent of Venom and the descendent has gone kinda insane.
