WOW! That episode was like Bob Haney dropping acid!
Jonah Hex has been kidnapped by Mongul (jr.) to hunt down fighters for War World so that Mongul can defeat his sister, Mongal, in combat. Jonah ends up having to hunt down Batman for Mongul. Once on War World, Mongul refuses to send Hex back to his own time. Eventually, Jonah helps Batman defeat Steppenwolf (Mongal's warrior) and then Batman & Jonah have to battle Lashina & Stompa, and then finally Mongal.
Once they finally face down Mongul, they can either destroy the time machine and release all of Mongul's prisoners or give up. Jonah tells Batman to destroy the time machine and he does. Once Mongul is subdued, Batman offers to take Jonah back to Earth and find a way home for him.
Jonah refuses, saying that things are just starting to get interesting. Batman teleports home and Jonah mounts up on his robot horse, taking his light based bullwhip with him. Just them Lashina appears, twirling her whips and says "Giddy-up" and then we see her sitting behind Jonah as they ride across War World.
Bob Haney looked down from heaven and smiled.
I'll get some photos posted next week.
