How about a Sky High version of KRH? Tsuna is the son of one of the best superheroes ever, but he gets designated as sidekick for whatever reason

Lol I thought you said a sky high version of bnha and I was like bro, that’s basically what it is already XDD Sorry, you’d think an author would be better at this whole reading thing. Anyways, yes this is an awesome idea!!!!

Tsuna’s father is a hero known as the Young Lion and everyone expects Tsuna to be just as powerful as his dad, which is why they’re so disappointed when he turns out to be a weak little sidekick because he can’t control his powers, and can’t even use them without taking 2 dying will pills first.

As time goes on though, for some reason he keeps attracting all these powerful people and he even manages to become the sworn rival of Kozato Enma.

Then at one point, one of his teachers (Reborn) notices that there’s actually a seal on Tsuna’s powers. And oops, wouldn’t you know it, Iemitsu remembers just then that he had asked his boss years ago to put a seal on his young son’s powers because he was too powerful and Iemitsu didn’t want Tsuna accidentally hurting himself.

And then when the seal is taken off it turns out that Tsuna is actually more powerful than most of his teachers even.
