The Mega Mondo Pop Cartoon-a-Con in sunny California marks the spot for mystery in this all-new original Scooby-Doo adventure! The Mystery Inc. pals -- Fred, Daphne, Velma, Shaggy and Scooby -- head to the annual convention, but they're not there to crack their next case. They want to meet their favorite comic book characters and see a megabucks movie premiere, an explosive big-screen remake of the classic cartoon The Adventures of Blue Falcon, featuring Shaggy and Scooby's favorite superheroes: caped avenger Blue Falcon and his trusty but bumbling robo-pup, Dynomutt.

Batman, Batgirl, and Robin forge an alliance with the Teenage Mutant Ninja Turtles to fight against the Turtles' sworn enemy, The Shredder, who has apparently teamed up with Ra's Al Ghul and The League of Assassins.

The comedic modern-day quintet takes on their 2003 counterparts when villains from each of their worlds join forces to pit the two Titan teams against each other. They'll need to set aside their differences and work together to combat Trigon, Hexagon, Santa Claus (that's right, Santa!) and time itself in order to save the multiverse.
