An alien movie producer captures two criminals, Beaver and Midge, in order to lure Superman, Batman, and Robin to an uninhabited area to film his movie. One by one, he throws bizarre alien creatures into the mix for the purposes of his film. But troubles start when the criminals escape and decide to use the alien's gadgets for themselves. Fortunately, the World's Finest team is able to capture the criminals, and a regretful alien promises to never mess with other people's destinies again.
Tommy and Brent save an alien, S'Loro, from being trapped on a planetoid being torn apart by quakes. As a reward, S'Loro exposes them to fumes he claims will protect them from harm. They experience narrow escapes from several hazards, but begin to wonder if it's true. It's not and S'Loro plans to hijack a duridium shipment, planting mines in the Planeteers' path to destroy them, expecting them to believe themselves charmed. But Tommy figured out the scam, noticing that a vulture sent earlier didn't act like a real vulture, so the Planeteers capture S'Loro and his men.
