The first installments of Cartoon Network’s new Justice League Action will bow as early as this Friday, and the latest look at our “Shazam Slam” beginnings trot out even more DC favorites. Arrow meets Constantine yet again in a new clip, along with Swamp Thing, Wonder Woman and more.

DC released another clip from the four-part premiere “Shazam Slam,” itself premiering on Friday, December 16 at 6:00 P.M. In it, an especially-accented John Constantine (Damian O’Hare) takes Batman, Superman and Wonder Woman to his home, before being joined by Green Arrow (sadly not Stephen Amell), Swamp Thing (Mark Hamill) and Plastic Man (Dana Snyder).

After ‘Shazam Slam,” new episodes will debut Saturday mornings on Cartoon Network, starting December 24. So reads the first synopsis:

In “Shazam Slam,” the villainous Black Adam battles Batman on the Rock of Eternity and unleashes a horde of Djinn 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 (voiced by Sean Astin) and The Wizard (voiced by Carl Reiner) - must hunt down and defeat each Djinn in order to yet again save the world from destruction.

In addition to the clip above, and already-announced returns for original Batman voice actors Kevin Conroy and Mark Hamill, the new Justice League Action features among its voice cast Patton Oswalt (Space Cabby), Ken Jeong (Toyman), Hannibal Buress (Mr. Terrific), Diedrich Bader (Booster Gold), James Woods (Lex Luthor), Rachel Kimsey (Wonder Woman), Jason Lewis (Superman), John DiMaggio (Lobo), Sean Astin (Shazam), and even Legend of Korra star P.J. Byrne as Firestorm.

Teen Titans Go! alum Sam Register will act as the show’s executive producer, along with Justice League and Batman Beyond vet Butch Lukic, Batman: The Animated Series’ Alan Burnett and Green Lantern: The Animated Series vet Jim Krieg as producers.
