Fan CastingAgent Venom

3 years after Spectacular Spider-Man 9 Flash Thompson while in the military loses his legs and is going to die but while on the battlefield, he obtained a part of the symbiote that had escaped during Spectacular Spider-Man 6. Now infused with the symbiote Flash has become the ultimate weapon and we see a montage over two years of him stopping terrorists, bombs, etc. One day Flash attends the execution of the man who killed his parents Cleetus Cassidy but before it a part of Flash's symbiote got into the gas chamber where before Cleetus died bonded with him and turned into Carnage. The movie ends with a battle between Flash and Cleetus in the prison where Flash has a hard time but eventually stops Cleetus and takes the symbiote back. Flash then decides to give his symbiote to the government so something like this doesn't happen again and Flash becomes a colonel in the military. Usually, to become a colonel you must have 22 years of experience, but Flash saved the world, so it balances out and it's a fictional world so I'm just going to justify it how I want.
