Here is the Captain from the Cat People spaceship.
I'm not sure but I think this is from an episode where Green Lantern is on trial in an outerspace court for the destruction of an entire world. Worse John Stewart the Lantern thinks he is guilty. While the Flash tries to play lawyer and defend him the rest of the League investigate. This episode features the Manhunters, the Green Lantern Corp, Guardians of the Universe and the Cat People (alien race made up for the beginning of this episode).
