I know what you mean about Superhero RPs here.

Anyway, I think I have an idea or two. I'll present some here to see if any work for your vision.

- The Judge/Harvey Dent: After years as Two-Face, the Face wanted full control and tried to destroy Harvey by ruining the non-scarred side. But after the deed was done, Harvey woke up alone, the Face having destroyed himself instead. Realizing that he can't go back to his normal live, Harvey decides to fight crime in the shadows as The Judge (Basically a reversal of Dark Knight Returns).
- Duke Thomas/Signal: Leader of the "We are Robin" youth movement and Batman's sidekick. Specializes in daytime operations.
- Gavin King/Orpheus: Specializes in stealth and infiltration. On police records a supervillain, Orpheus is actually a member of the Bat-Family, working inside the underworld by pretending to muscle in on the rackets and then disposing of his "rivals" (Think of the Green Hornet)
- Charlie Duffy/Nice Batman: A savant Batman-fan. Though he has received training from Batman himself, Charlie's true strength is the community spirit of his neighborhood.

Other roles can also be taken when needed.
