Miracleman by Neil Gaiman

An ordinary, repressed man discovers he can transform into a near‑omnipotent superhuman and must piece together fragmented memories of a heroic past while confronting the moral and psychological consequences of godlike power; as he and other awakened superbeings attempt to remake a broken world and pursue an uneasy utopia, the narrative probes identity, trauma, the corruption of childhood myths, and whether benevolent intention can excuse the coercion and loss that absolute power inevitably brings.
