Yes. That is the criteria. I wasn't looking for Kid Psycho. I'll say that the character is certainly more well-known, and their namesake (superhero identity) has been used by others in-universe since their death. As far as I know, they have never been resurrected at all in New Earth, but I may be mistaken. They have since appeared in cartoons and such.
