story exchange

OK, each story has a setting, plot, and characters. But I'm sure most writers have some ideas that are missing one or more of those elements. Here, we post those ideas and try to combine them - one author's characters without a setting get put in another author's setting without characters. If the combination works well, try to write it!

I'll start it off with an orphaned setting:

A world where superpowers are gotten by a kid with a certain genetic predisposition undergoing severe trauma over a lengthy period of time before puberty. As a result, most superpowered kids have psychological issues related to trauma, which explains why a lot of them are causing mayhem.

What if we have concepts for characters as well as a setting, but no ideas for personalities? Like I've got this thing about two twins, a boy and a girl, who join a guy who seems to be a god who has forggoten his origins, and even his name on journey where they discover All Myths Are True.

^^ Strange, I've had an idea bouncing around where trauma is a prerequisite for superpowers.

^ Do you need personalities for the boy, the girl, or the god?

Boy and girl.

How about one twin is a Cloud Cuckoolander Spanner in the Works and the other is a non-villainous Chessmaster who can actually predict what his/her twin will do?

That sounds cool, and for your setting maybe there's a cabal that brutalizes kids to make superhumans for their schemes.
