Patriot
Everyone knows that Steve Rogers was the only successful super-soldier created by Project: Rebirth, right? Actually, no. It was later revealed in the comics that the government continued the experiments on African-American test subjects. The result was another, secret, Captain America: Isaiah Bradley.
In the modern-day, his grandson Eli Bradley attempts to make a name for himself as Patriot. The thing is, though, he hasn’t inherited his grandpa’s powers. However, his heroic heart and bravery is enough and Eli joins the Young Avengers – alongside other adolescent heroes including Hulking, Wiccan, Speed, Iron Lad and Miss America. In a twist, he sacrifices himself but is resurrected with a blood transfusion that finally gives him Isaiah’s abilities.
Patriot is a great character with a rich story to explore, then, and the obvious home for him in the MCU would be in a Young Avengers movie. Seriously, the idea of a teenage spinoff of the Avengers would be such an obvious big hitter for the MCU that we’re surprised we haven’t heard anything about it happening yet. Maybe it’s one of those mystery movies that’s been given a release date?
