The Punisher is a vigilante who considers murder, kidnapping, extortion, coercion, threats of violence and torture to be acceptable crime fighting tactics. Driven by the deaths of his wife and children, who were killed by the mob when they witnessed a gangland execution in New York City’s Central Park, Frank Castle wages a one-man war on the mob and all criminals in general by using all manner of weaponry. A war veteran, Castle is a master of spatial planning, martial arts, stealth tactics, hand to hand combat, and a wide variety of weapons.
