In a digital to linear play, Cartoon Network is expanding the world of Kyle A. Carrozza’s 15-second CN Anything app series Mighty Magiswords into an 11-minute TV series that will debut on the US net September 29.

A new companion app is set to launch later this fall that will help connect fans to more than 400 pieces of original Magiswords content, including interactive shorts, digital games and narrative vlogs hosted by the show’s main characters and “warriors for hire” Prohyas and Vambre.

The show’s heroes will also support the new series by appearing as on-air hosts to introduce Cartoon Network programs and events.

Launched last year as CN’s first original digital series, Mighty Magiswords follows the comedic adventures of a brother-and-sister warrior duo who wield a collection of magical, sometimes functional, swords to battle with names like Zombie Pumpkin and Excaliburger.

Prior to the launch of the premiere episode, “The Mystery of Loch Mess,” a sneak-peek  of the new long-form series will debut on the Cartoon Network app September 2.

Created by Carrozza (The SpongeBob Movie: Sponge Out of Water, Fish Hooks), and produced by Cartoon network Studios, Mighty Magiswords features guest stars such as Weird Al Yankovic, Jack McBrayer, Dave Coulier and Tom Kenny.
