Superman and Martian Manhunter are abducted by extraterrestrial slave traders and are sold to a planet of the despotic ruler Mongul where the population spends its time watching aliens in mortal combat in an enormous colosseum. Green Lantern and Hawkgirl set out to rescue them.
* BelligerentSexualTension: Pretty much the entirety of the episode's subplot, which involves Green Lantern and Hawkgirl traveling across space in search of Superman.
* BreadAndCircuses: Mongul's empire drew obvious parallels to the Roman Empire. The Martian Manhunter finds out there's mass unemployment and poverty, but people are kept entertained by the [[BloodSport gladiatorial games]].
* FascistButInefficient: Despite his iron-fisted cruelty, Mongul is shown to be an extremely poor and incompetent ruler of War World, as the planet has suffered from mass poverty and unemployment under his leadership. He manages to keep the populace docile by providing [[BreadAndCircuses entertainment]] in the form of the gladiatorial games.
* FinishHim: After Superman defeats Gladiator Draega, Mongul orders Superman to do this. [[TheMessiah Being who he is]], he refuses, even when Draega himself asks him to do so.
* [[IHaveYourWife I Have Your Planet]]: Mongul reveals that he has blackmailed Draega for years, pointing a large DeathRay at his home planet and threatening to destroy it if he refuses to fight in his games.
