The other obvious place for Netflix and Marvel to draw on is The Punisher's very first appearance in the comics. If Jon Bernthal's Frank Castle is being introduced as a totally new player in Hell's Kitchen in Daredevil's second season, why not use his first appearance in New York on the page as a template? But the only thing is, The Punisher isn't classically a Daredevil villain. He was originally a foil for your friendly neighbourhood wall crawler, debuting in 1974's The Amazing Spider-Man #129, where he's been hired by The Jackal to kill the webhead. Thankfully, Castle reneges on his boss when it turns out he's setting him up for mass-murder. It's a classic story, and one that could make the leap to the small screen without much modification. Get rid of The Jackal, because he's a Spidey villain (and a terrible one at that, tied into the much-maligned Clone Saga), and have somebody else hiring The Punisher to do in Daredevil because he's bad for business. Job's a good'un.
