Based on the hit trading card universe created by Joe Simko (Garbage Pail Kids artist) and Ira Friedman, and written by Sholly Fisch (Batman, Superman, Scooby-Doo), Craniacs has expanded from collectible trading cards into an exciting graphic novel series. When two planets collide, forming one world, two distinct skull-faced societies are forced to coexist. One side is the wild, Stone Age civilization of RETROVIA. The other is the systematic, ultra-futuristic society of FUTERRA. When these opposing worlds collide, skulls will clash in epic adventures filled with action, comedy, friendship, and unforgettable characters.
