There are at least two versions of Clark being a Batman style character under a red sun. One where he and Jimmy Olsen are in the bottled city of Kandor and one where he and Lois are on a version of Krypton. In both cases he used Nightwing and Flamebird as identities. The story about that was what gave Dick Grayson the idea to use Nightwing.
