The Savage Dragon
Chicago cop, Frank Darling, discovers a huge green-skinned mutant named Dragon who suffers from amnesia. In the hope of uncovering his own identity, Dragon joins Chicago P.D. and battles evil mutants led by the mysterious Overlord.

The Fiend, who feeds on hate and uses human bodies as hosts, inhabits a skinhead, the racist Sgt. Howard Niseman and then a self-help guru, who's really a hatemonger. The Dragon tries to defeat The Fiend by goading him to try to inhabit his body.
