Looks like those knives have seen some use recently.

And rope. Lots and lots of rope.

"He does not seem to have any supernatural abilities but makes up for it with ruthlessness, cunning and training."

Sharpfury is regularly shown taking on characters that do have supernatural abilities and he is very rarely shown being on the losing end despite his lack of 'powers'. While he may not officially have a defined supernatural power of 'luck', at least that has been publicly disclosed, he certainly functions exactly as if he had one, or as if he were secretly a much more powerful being like a demon lord or demigod that is just pretending to be an unpowered normal.

IMHO, he'd be a more interesting and believable character if he were sometimes shown losing due to the fact that he doesn't have powers. I think I can recall a couple of examples but they're few and far between.

Very nice! Reminds me of Punisher but evil. No, scratch that. Kraven would be better, especially given the upcoming movie. It just fits!

Sharpfury always reminded me of Snake Plissken, but that's probably the eye patch and general outfit.

Still don't get why this villain doesn't lose fights way more often.
