The four new series will be:Scooby Apocalypse, co-written by Keith Giffen and DC Entertainment co-publisher Jim Lee, with art by Howard Porter.

As the result of an experiment gone wrong, Scooby and the gang will have to deal with a world where monsters are real, thanks to a nanite virus that is slowly transforming the world into a far stranger place.

The Flintstones, written by Mark Russell with character designs by Amanda Conner.

Taking the concept back to its roots, Flintstones will be a satirical sitcom that uses the stone age to parody and comment upon the modern world.

Future Quest, written by Jeff Parker and illustrated by Evan "Doc" Shaner.

Combining Jonny Quest, Space Ghost and Birdman, the series will mix and match the various "adventure" heroes of Hanna Barbera's output in a new shared universe.

Wacky Raceland, written by Ken Pontac, with art by Leonardo Manco and designs by Mad Max Fury Road's Mark Sexton.

Taking the original madcap race series in an unexpected new direction, transforming the series into a literal race across a post apocalyptic wasteland in search for a promised utopia at the finish line. Oh, yeah; and the vehicles can think for themselves, this time around.

"I can’t think of anyone that doesn’t look back at these characters with anything but fond memories," DC Entertainment co-publisher Dan Didio said in a statement accompanying the news. "With this initial lineup of titles and talent, we’re excited for fans to experience the reimagining of these Saturday morning classics with a more modern and contemporary look and feel."

All four new series will launch in May.
