Supreme Power, Volume 1 by J. Michael Straczynski

A secret government program recovers a seemingly invulnerable alien and tries to shape him into a controllable asset, while a morally driven but brutal masked vigilante and other emergent superhumans force confrontations that test loyalties and ethics; the book reimagines classic superhero archetypes through a darker, realistic lens, exploring how absolute power, national security, and civil liberties collide as politicians, scientists and vigilantes clash and ordinary people are caught in the crossfire.
