Can humanity survive all-powerful heroes and villains transformed into ferocious beasts? And as the world goes wild, can Raven discover a way to save Beast Boy? If that's not enough...who is Doctor Hate, a mysterious new threat unleashing their own unique brand of chaos? Friends will fall. Heroes will rise. And nothing will ever be the same again. Earth is about to become...Beast World. This volume collects TITANS: BEAST WORLD #1-6 and TITANS #6-7 and sets the stage for the next evolution of the DC Universe!
