"Hanna Barbera's classic cartoon characters meet some of the DC Universe's greatest superheroes! These massive crossovers are sure to thrill, whether your favorite characters are teaming up, or facing off. Trapped in a strange rift in time, Green Lantern and Space Ghost are forced to battle a variety of foes--and each other! Mistaken for metahumans, thrown in the bowels of Belle Reve, the animal rock band Banana Splits are recruited by Amanda Waller for a secret mission: to save the Suicide Squad! Adam Strange is blasted through multiple dimensions only to land on Earth! There, instead of super-powered beings and legendary crime-fighters, he encounters Jonny Quest, Hadji, Dr. Quest and Race Bannon--and they're the only ones who can help him get home. In the midst of an alien invasion in the twenty-fifth century, Booster Gold must dive deep into the prehistoric past to see what happened the last time they hit the planet. In this bygone era, Fred Flintstone and Barney Rubble must help Booster learn the truth and return to his own time armed with the information that will bring down the invaders."--
