I want a disastrous and chaotic found family with Hero x Villain:
An adult Hero who has underlying traumas that they refuse to admit and acknowledge. They are so tried from fighting. They literally running on coffee, fear, and stress. Probably have white hairs and eye bags.
The small group of sidekicks who wants to be trains as an heroes but too chaotic and “share a single braincell” . Trying fight the villains but they only known how to self-defend themselves from Hero’s teaching because Hero doesn’t want them to suffer from a hero job. Hero has to stop them from going in danger or acting like an heroes. Probably calls Hero, “mom” and villain “dad”.
An adult Villain who has strong mortal code against children. They were suspect that Hero is putting these Sidekicks in danger, but only to realize that Sidekicks aren’t actually sidekicks and Hero is trying to protect them. Going easy on the kids during the fight before Hero drag them away from the fight. Probably falls in love with Hero.
