AAside from Frank Castle (The Punisher) the film incorporates some characters from the comic's many incarnations.Jigsaw - Billy Russo (Russoti in the film) considered to be The Punisher's archenemy, is laregly unchanged. He is a mutilated madman obsessed with the Punisher. In the comic he was frequently depicted with a comically overstated eye. This was removed for the film, but as a tribute, one of his eyes is similarly disfigured.Detective Soap - While retaining the "loser" qualities of the character, the film deletes much of his backstory and his complex relationship with Frank. The movie assumes that he has been working with Frank from the beginning and that he isn't quite as inept as his comic counterpart.Microchip - In the comic he provided Frank with intel on his targets due to the fact that he went through a similar crisis. He worked with the Punisher for many years before they had a falling out. The film version of the character is little more than an armorer and it's assumed that he's helping the punisher to aid his dying mother.Pittsy and Ink - In the comic they were a duo of mob enforcers who were equally anti-social and psychopathic. The film changes them to more standard "goodfellas" and it's implied that they are father and son.Paul Budiansky-From Widowmaker, though changed from a hero NYPD detective to a coke head FBI agent.Cristu and Tiberiu Bulat-From The Slavers, human traffickers from the Balkans, war criminals and probably the most ill fated of the Punisher's enemies. However in the movie they're typical Russian mobsters. Much like what they did to Pittsy and Ink.Cesare Gaetano-A name change from Messimo Cesare who is killed right off the bat in In the Beginning. The killing of the character starts a series of large problems for The Punisher.Maginty-From Kitchen Irish, a great character cut down to a barely visible supporting role. His death in the film was originally used in In the Beginning in an attempt to kill Pittsy, though it failed miserably.
