Via IGN’s press release:
In ‘Teen Titans Go! Vs. Teen Titans,’ the two teams are pitted against each other when villains from each of their worlds join forces. The two very different Titan teams will need to set aside their differences and work together to combat Trigon, Hexagon, Santa Claus (yes, Santa Claus) and time itself in order to save the universe.
Produced by Warner Bros. Animation, DC and Warner Bros. Home Entertainment, Teen Titans Go! Vs. Teen Titans features the beloved multi-series cast of the past 17 years: Greg Cipes as Beast Boy, Scott Menville as Robin, Khary Payton (‘The Walking Dead’) as Cyborg, Tara Strong (‘Batman: The Animated Series’) as Raven, and Hynden Walch as Starfire.
The cast also spotlights Kevin Michael Richardson as Trigon/Hexagon, Robert Morse (‘Mad Men’) as Santa Claus, Grey Griffin as Mrs. Claus, Rhys Darby (‘Flight of the Conchords,’ ‘Voltron: Legendary Defender’) as Master of Games, Sean Maher (‘Firefly,’ ‘Serenity’) as Nightwing, and four-time Grammy Award winner “Weird Al” Yankovic as Gentleman Ghost and Darkseid.
‘Teen Titans Go! Vs. Teen Titans’ is produced and directed by Jeff Mednikow (‘Be Cool, Scooby-Doo!,’ ‘Teen Titans Go!’) from a script by Marly Halpern-Graser (‘Batman vs. Teenage Mutant Ninja Turtles’) and Jeremy Adams (‘LEGO DC: Batman – Family Matters’). Sam Register is executive producer. Executive Producers are Aaron Horvath (‘Teen Titans Go!,’ ‘Unikitty!’) and Michael Jelenic (‘Teen Titans Go!,’ ‘Batman: The Brave and the Bold’).
