This deluxe hardcover collects Supreme Power Vol. 3: High Command and Supreme Power: Hyperion, plus extras. In High Command, Hyperion, the Blur and Nighthawk - in their first adventure as the newly formed Squadron - have a long-overdue showdown with the super-powered serial killer who's been terrorizing the nation! But will they live long enough to stop him? Plus: What does the most powerful being on the planet do when he finds out he's been manipulated, and that his whole life is practically a lie? How will Hyperion react, and what does that mean for the rest of humanity - and the government that's organized these deceitful machinations? And in Hyperion, Mark Milton suddenly finds himself both alone and hunted now that the world knows his dark secret. Four new super-powered individuals - each based on a character from the original Squadron Supreme - are after his hide, and they've got the will and means to take him down! Collects Supreme Power #13-18, Supreme Power: Hyperion #1-5.
