Barracuda

Bringing Barracuda into the Punisher show would tie in nicely with what we already know from the second season of Daredevil. Thus, the villain would be someone sent by the same generals responsible for the death of Castle’s family. And, once again, this would be a villain to match Castle’s physical and tactical skills.

Obviously, the story could pull from the Long, Cold Dark comic book, with the Punisher unwillingly helping Barracuda become a feared criminal boss. However, I guess some parts of the storyline could be left out. I am talking, of course, about the daughter Castle has.

This wouldn’t fit with what we already know about the Punisher. Plus, having a surviving family member would somehow steal from the character’s motivations. So I’d leave that out.

But Barracuda is, probably, the one villain that should definitely appear in the Punisher TV series. Even more than anybody on this list. He is powerful, he is a great strategist, and he can endure whatever pain the Punisher might inflict on him.

He is perfect for the Netflix corner of the MCU.
