If I leave them where they're at, I forget wtf they're proficient in.

So I try to name them something meaningful pertaining to battle, or politics, etc.

I use such random movie character or video game character names.

Like Vin Diesl for an attack hero.
Mother Brain for an intelligence hero.

Some are random or from books I write.

Black Amber for attack hero.
Autumndeath for attack hero.

Sometimes its good to go on themes
