Irredeemable, Vol. 1 by Mark Waid

When the world’s most adored superhuman abruptly becomes its greatest threat, civilization reels as his former teammates race to survive, uncover the truth behind his terrifying transformation, and devise a way to stop a nigh-unstoppable force they once called friend. This opening arc follows their frantic efforts, internal fractures, and chilling insights into the fallen icon’s past, launching a grim deconstruction of hero worship, power, and the razor-thin boundary between guardian and monster.
