During Season 2 of Netflix's Daredevil we meet Frank Castle (aka The Punisher).
Looking at his seemingly unnatural ability in combat and survival (video below), is it plausible that he has superpowers?
Quote from Jon Bernthal via Screenrant quoting a GQ article
“I’m working on The Punisher now. You know, this whole superhero-comic-book thing is something I had zero interest in being a part of. The guys that I really, really respect as actors seem to have kind of purposely stayed away from that. I don’t mean that I’m above that or anything, just that it was not for me. But then when I got to know a little bit about this character… He ain’t got a fucking cape. He ain’t got any superpowers. He’s a fucking tortured, angry father and husband who’s living in this unbelievable world of darkness and loss and torment. Frank Castle resonates with me.”

"I wasn’t desperately trying to get into the comic book world. [laughs] For me, it’s about the human being. He has no superpower. His superpower is his humanity. It’s his drive, his rage, and his loss. I could never have played this part if I weren’t a husband or father. Until you really understand what it’s like to love somebody more than yourself and to willingly give your life for them, only then can you understand what it would mean if they were taken from you."
Marvel lists Frank as having no superpowers.
His "unnatural" ability in combat and survival is similar, if not more pronounced in the comics. The Frank Caste we see in Daredevil season 2 is just starting his rounds as The Punisher. This is still his origin.
Frank is a war vet, and his skill set comes from there. He's highly skilled, exceptionally armed, and very unstable. He's a big ball of anger, crazy, and ammo.
Other than that there's no powers here, nor can I see them writing anything into his character. It's too much of a deviation from who The Punisher really is.
