DC announced this week in Cannes at the MIP Junior conference that the new DC Nation Block on Cartoon Network will include shorts by Lauren Faust called Super Best Friends Forever.

The shorts, likely about seven minutes apiece, will star three of DC Comics’ famous heroines, Supergirl, Batgirl, and Wondergirl (okay, so maybe two famous heroines and one not-so-famous heroine). Judging by the announced concepts in the other DC Nation shows, Faust will be free to mold the characters to her desire (The Batman show, for example, turns Robin into a female ninja, so anything goes), and to come up with whatever original stories and conflicts she wishes. Knowing Faust, the show will likely revolve around themes of teamwork and friendship, while each of the three girls will have a distinct role in the group and a personality which sometimes conflicts with the group’s goals.

Faust is the creator of the well-regarded PowerPuff Girls shorts from the 90’s, and more recently is responsible for My Little Pony: Friendship is Magic, which has created an unlikely following among the valuable 18-35 year old male demographic.

The announcement was made during the event’s keynote speech by Sam Register, Executive VP for Creative Affairs at Warner Bros.

He talked a lot about cool DC stuff, and tried to be educational, but the news for Faust fans is buried in a quick summary of the DC Nation Block which will air on Cartoon Network starting with the new Green Lantern: The Animated Series in January 2012.

“The block will include Aardman Animation creating new claymation Batman shorts, Plastic Man animated shorts, and the creator behind My Little Pony: Friendship is Magic working on a series of animated shorts teaming Wonder Girl, Batgirl, Supergirl called Super Best Friends Forever, SBBF. Additionally, there is also a series of Doom Patrol animated shorts in production. The block will also host a series of behind-the-scenes videos, special interviews, and much more. DC Nation, slated to run for at least three years on Cartoon Network, will debut in Spring 2012 with Young Justice and Green Lantern: The Animated Series.”

If you’d like to check out the entire keynote, it’s below, but there are no further details about Faust’s involvement—just a really poor image of the Supergirl illustration (right) just after the 32 minute mark, which gives a a bit of a sense of the style of the show’s animation. There are, however, some cool clips of some of Warner Bros. other new cartoon shows, and lots of interesting tidbits about stuff they’re working on that are not being produced by Faust.
