Darkman (1990)

When thugs employed by a crime boss lead a vicious assault on Dr. Peyton Wilder (Liam Neeson), leaving him literally and psychologically scarred, an emergency procedure allows him to survive. Upon his recovery, Wilder can find solace only by returning to his scientific work developing synthetic skin, and seeking revenge against the crime boss. He assumes a phantom avenger persona called Darkman, who, with malleable facial qualities, is able to infiltrate and sow terror in the criminal community.
