Frankenstein, Agent Of S.H.A.D.E., Volume 1 by Jeff Lemire

Reborn centuries ago and pressed into service by a shadowy government agency that handles the paranormal, a patchwork monster-turned-agent is sent on covert missions against supernatural threats and monstrous conspiracies; as he hunts fiends and infiltrates strange, otherworldly plots, he grapples with his own violent nature, the moral cost of obedience, fragmented memories of a lost past, and uneasy alliances with eclectic colleagues, all while the agency’s secrets and the wider human fear of monsters force him to question who — or what — he truly serves.
