For the Teen Titans GO! Halloween special this year, the Scooby gang will be crossing over with the Teen Titans GO! characters. The episode, called "Cartoon Feud," will have a villain called Control Freak forcing the Titans and the Scooby gang to compete on Family Feud together.
It's the first time that Scooby and Teen Titans have crossed over in television, though Scooby did previously crossover with Teen Titans Go! in the Scooby-Doo! Team Up comic series in issue #4.
The episode will air on Friday, October 4 at 5pm central in the United States, according to AnimationMagazine (note that the source incorrectly says it is a Monday, though October 4 is indeed a Friday).
