I would agree the wolverine/bearcat would have to be considered both dangerous and mysterious NA critters.

However a plain old wolf gives me the creeps, I have had bears come a tree and not even felt as scared as I do when a wolf looks my way...them eyes look right through you...spooky!!!!

Although slow and pokey a badger can be a mess to deal with, I came face to face with one a few years back while waterfowl hunting and he wasn't to pleasant...the 12 gauge and 3-3" BB's slowed him down but I needed a pee break after that encounter
