Flash Thompson as Venom is really cool. The graphic novels often show his complex relationship with the symbiote. It's a different take on the Venom character compared to Eddie Brock. Flash brings his own military background and sense of honor to the role.

He might be intrigued by Flash Thompson's bravado and see it as a starting point to shape him into a better person. He could offer Flash some cool tech gadgets and in the process, form a friendship. Stark would likely use his wit and intelligence to get through to Flash and show him a different way of looking at things.
