Hm, I’ve got quite a few, but off the top of my head I’d say Anita Fite (Empress), Greta Hayes (Secret) , Charlie Gage Radcliffe (Misfit), Lilith Clay (Omen), Traya Sutton, Derek James (Sideways) and Ernie Edgars.
Edit: oh, and Amy Winston (Amethyst), although I don’t know know if she can really count her as obscure, what with her new miniseries coming out
Edit Mark 2: Also Garth (Tempest) but I’m not sure if he counts…feels like he’s the kind of character a lot of people know about but not many people actually care about
