While in pursuit of one of the Djinn brothers, Batman becomes possessed by the djinn, Uthool, who seeks to use the reactor core in the Hall of Justice to destroy the Earth's Mantle and open a gate to the underworld.
This episode contains examples of the following:
- One-Winged Angel: Uthool, while still in possession of Batman's body, transforms into a demonic version of Batman.
- Stealth Pun: Booster Gold and Batman have a standing appointment to spar in the Hall of Justice gym. Self-aggrandizing Booster has slapped up a huge decal of his face on the ceiling making it look like he owns it, Gold's Gym.
