The Fist Of Flame
Diana Prince, the currently depowered Wonder Woman, and her friend, blind martial art master I-Ching, go looking for detective Jonny Double, to find him missing, and are attacked. After fending them off, Diana is instructed to get a ruby called "The Fist Of Flame" in a hidden village in Tibet. Diana and I-Ching go there, and as Diana is about to take the ruby, ends up fending off Catwoman. Catwoman is also there to take the ruby, but both get caught by the temple guards, and are forced to fight to the death. Diana works with Catwoman to save both their lives, and with I-Ching (who finds out from Catwoman it is his missing daughter, Lu San, who sent her there), they escape with the ruby, but, then, in the cave, the world spins the trio find themselves face to face with barbarians in another dimension.....a perfect place to end the issue!
Fangs Of Fire
These two men were looking for "The Eye Of The Ocean", a jewel Lu San (who was holding Jonny Double captive) was using to build a dimensional breach to the land of Nehwon, so she could loot its treasures. The five go to face the sorcerer Gawron, who was protecting the dimensional energy transfer matrix machine in Nehwon. I-Ching ends up holding both gems, and brings Lu Wan, her men and Jonny to Nehwon. In the confusion, I-Ching opens a portal to Earth, with the five and Jonny going home, and I-Ching taking "The Fist Of Flame" and the Grey Mouser taking "The Eye Of The Ocean" as they go through, leaving Lu San and her men trapped with Gawron.
