THE DEFINITIVE ORIGIN STORY CONTINUES!
Propelled by a new sense of purpose and a clear target for his vengeance, Mr. Terrific dons his superhero costume (or the closest approximation he can scrape together from his workshop) for the very first time to lay siege to Athena Prescott's tower at the center of Gateway City. But while he's got his sights set on Prescott...she's got her eyes on him too. And the third-smartest man in the world might just find that you can't bring T-Spheres to a gunfight and expect to walk out alive...
Meanwhile, in the present day, Mr. Terrific's surprise encounter with an Apokoliptian hellhound lands him in some dimension-hopping hot water!
