Justice League Action: Season 0, Episode 2

0 - 2: Shazam Slam

This one hour special has the villainous Black Adam battle Batman. At their battle on the Rock of Eternity a horde of Djin is unleashed determined to turn the Earth back to its pre-human, volcanic state. Affected by the otherworldly powers of these primordial monsters, Batman becomes possessed and is turned into a giant flying Batmonster laying waste to the Hall of Justice, with only Superman capable of taking the fight to the Dark Knight. One by one, the Justice League - with the help of Shazam and The Wizard - must hunt down and defeat each Djinn in order to yet again save the world from destruction.
