Wasn't one of them from the animated series?
EDIT - Montoya.
Montoya's been in the comics for a while. Crispus Allen was introduced right after No Man's Land. Maggie Sawyer was from the Superman comics. Bullock's been around for a while too. Longer than Montoya. The others are originals.

Buy The Gathering!
May I just say that I want so badly for that comic to be adapted for television? Because I fucking do. It would beat the hell out of Birds of Prey or Smallville.
This is my signature.
