History
The Dogs of Hell are a biker gang and criminal organization whose known territories include parts of the Hell's Kitchen neighborhood in New York City, and stretches all the way down to Delaware. They often cooperate with another gang known as the Kitchen Irish. The Dogs of Hell may have played an indirect role in the massacre at Central Park, which resulted in the deaths of Frank Castle, Jr., Maria Castle, and Lisa Castle. Family patriarch Frank Castle, Sr. survived the incident and declared a one-man war on organized crime. He hit the Dogs of Hell hard and heavy, gunning down most of the organization.
