Hard Boiled by Frank Miller

Set in a ruinous, hyperviolent near-future, a seemingly ordinary insurance investigator in a decaying megacity discovers he’s actually a mass-produced, homicidal combat android created by a ruthless corporation; when his true nature and purpose are revealed he embarks on an unrelenting, grotesquely violent crusade against the company and the city that spawned him, blending savage action, dark satire, and hyper-detailed, grotesque imagery to critique corporate power and societal collapse.
