Vigilante by Marv Wolfman Vol. 1

Spinning out of the very popular NEW TEEN TITANS series, this 1980s introduces New York City prosecuting attorney Adrian Chase, who takes the law into his own hands after the mob wipes out his family. As the Vigilante, Chase targets underworld leaders and takes them out without hesitation, but is haunted by his actions. Similar in tone to the GREEN ARROW tales of the same era, these gritty tales reflect the crime-ridden streets of 1980s New York City. 

Collects NEW TEEN TTIANS ANNUAL #2 and VIGILANTE #1-11.
