I like Frank Castle. When it comes to homicidal vigilantes he's my go to guy. However I believe he is far better suited for the MAX line and not the standard Marvel Universe. To me he is one of those characters that just works better in a world where superheroes are either absent or there are only a small handful. However I don't believe the Marvel Universe shouldn't be without a Punisher, and as such here's my take on a new Punisher idea that I believe COULD work.
Tony Russo is an NYPD officer in New York. His family is the notorious crime family the Russoti's and he changed his last name to avoid association with them. He lives with his fiancee and their two year old daughter and all seems perfect. However it all comes crashing down when his brother is landed in jail and his family tries to force him to do something as he's a policeman and it's about time he did something for the family. He refuses, he's disgusted with his family's ways and his brother ends up going to prison where he ends up killed. The Russoti's doesn't take too kindly to this and order a hit on Tony and his family. He's not home at the time and comes home to find his fiancee and daughter killed. He hears the hit men outside, having come back to finish the job, and quickly grabs some civillian clothes from his closet, a white shirt with a black skull on it, some black jeans, and a leather jacket.
He runs out of the house, managing to steal the hit men's car when they enter the house, and drives. He thinks about his options, knowing he simply can't report it because almost every cop in a high up position is corrupt and would leave it alone or kill him. He stops and checks the trunk of the car, finding an arsenal fit for an army. Being a gun enthusiast, he knows how each of them works and his course of action becomes clear. Those who killed his family must be punished.
Does this sound like possible new series?
