Imagine the Marvel and DC universes have always been one, merged together. All the heroes you've always known all in one universe, fighting against villains in the name of truth and justice. The Avengers, the Justice League, the Teen Titans, the X-Men, and many other teams coexsisting together, fighting the good fight. Eventually, those heroes (and villains,too), had children of their very own. And those children grew up, settling into their own roles as heroes, villains, or whatever else they chose to become.
Capes and Cowls is a Marvel and DC comics nextgen roleplaying game, taking place in a universe where the two universes have always been merged.
