Miracleman, Book One by Neil Gaiman

A mild‑mannered journalist gradually remembers that he transforms into a near‑omnipotent being when he speaks a trigger word, and as he reclaims that superhuman identity he is forced to confront fabricated memories, hidden origins and the moral consequences of godlike power; the narrative follows his uneasy return to a changed world of other awakened superhumans and the unsettling truth that challenges both his sense of self and the fragile society built around these powerful beings.
