Fans are overly excited about the news of Tom Hardy agreeing to play Eddie Brock in Sony's Venom. While Eddie undoubtedly has the claim of the first and most notable Venom, he's not the ideal host for #Sony to build around. Eddie's story will need to be altered to fit in a world that doesn't totally revolve around Spider-Man, and because of that, Flash Thompson makes more sense.
Flash has a greater heroic back-story from his connection to Spider-Man, and more importantly his struggles with PTSD and alcoholism. Though he has some involvement with Peter, his story can be told during his time as solider fighting in the Iraq war and beyond. Admittedly, the details in Flash's story aren't as fleshed out as Eddie's, whose path is directly affected by his hatred of Spider-Man (hence his role as a villain). However, with a lack of Spider-Man comes some freedom ─ Flash's story doesn't have to have the #PeterParker, or #SpiderMan anchor.
A Redemption Story From Bully to War Hero
Flash was a star athlete and a total douche who loathed the nerdy Peter Parker. Unbeknownst to anyone, Flash went home to an abusive alcoholic police officer for a father. Like many cases, the popular, often abused Flash took his anger out on Peter, whilst unknowingly geeking out over his alter-ego, Spider-Man.
As time passed, and high school became a distant memory, the two enemies became friends. Flash dropped out of college to enrol in the military ─ fighting in the war against Iraq. While on tour Flash's platoon was ambushed, and in heroic fashion he saved the life of his commanding officer, at a tragic cost; the former athlete was now a double amputee. But, with the help of friends, Flash recovered and went on to become a gym teacher.
Despite his apparent recovery the congressional medal of honor, Flash still suffered from PTSD. His ex-girlfriend, who was now a physical therapist, continued to help Flash along, helping him to dominate in the National Veteran Wheelchair Games. During this time the government successfully separated Venom from Mac Gargan, and consequently the Department of Homeland Security now housed the symbiote. The DHS attempted (and failed) to bond the parasite with any other human host, until #FlashThompson.
More Heroic Than Eddie Brock
Eddie struggled to control #Venom, which lead him down a path of destruction. The former reporter constantly clashed with Spider-Man. Through that time he became part of Spidey's rouge gallery. Even though Eddie did use the symbiote for good he still struggled to control it, thus Marvel once again opted for Eddie to don the black suite as a bad guy.
However, Flash, unlike anyone before him, was able to control the symbiote and with it he became the military's ultimate soldier, a weapon stronger and more powerful than Spidey himself. Flash's Venom story writes itself, a military weapon sent on missions, but the former war hero would go on to do many great things.
Flash Thompson the Avenger
Mainstream fans may not be aware of the other avengers, formerly led by Steve Rogers, but they could if Sony decided to use Flash instead of Eddie. With a few member tweaks, a spinoff with #AgentVenom leading a secret group of heroes being asked to perform missions the Avengers can't would be great.
The Secret Avengers is a post Heroic Age take on the anti-registration group Steve Rogers formed during the original Civil War. Though Flash was not part of the original group, he was later recruited to join the group when the original members disbanded, after the events of Fear Itself. Flash, along with Hawkeye and Human Torch, teamed up with lesser known #Marvel heroes Captain Britain and Giant Man to form the new Secret Avengers.
There's even a chance that Sony could do something further apart from the current Avengers with the Dark Avengers. As mentioned before Flash's origin will be tweaked anyway, so why not take McDonald Gargan's Dark #Avenger story-arch and apply it to Flash? The Dark Avengers were formed by Norman Osbourn who is now the Iron Patriot, he was also the head of H.A.M.M.E.R, and in charge of the Thunderbolts. With #Disney and #Fox having control over many of the Marvel characters, certain characters like Bullseye, Ares, Moonstone, Noh-Varr, and Daken could work. The former war hero would be perfect as the leader, plus with Sony and Disney playing nice we can only imagine possibilities.
