For this poll, I’m looking for the scariest, horror-themed, obscure Marvel super villain. I know Galactus and Thanos would certainly be terrifying to encounter, but I’m looking for ones who fit solidly in a horror setting by either their look, origin or power. I’ve also left out the very well known villains such as Dracula, The Green Goblin, Carnage and Venom. I’ve listed several I could think of but can update any suggestions posted in the comments provided they fit the criteria. You can vote for as many of the villains as you like.

Hybrid, the Dire-Wraith/half-Human menace from ROM-hideous appearance in its natural form, utterly evil, and used its’ psychic powers to kill victims in grisly ways.
Absolutely! I loved that one.
Wow. Carrion and the Demogoblin brought me back to a time in Amazing Spider-Man I’d rather forget, LOL. The 90’s was not a pretty time for Spidey. I picked Wendigo but I could have gone other ways. I really want to see how this poll comes out.
I did like the original Carrion storyline quite a bit, but The Demogoblin stuff wasn’t so great. He had kind of a cool look at least.
At one point Carrion, the Demogoblin, Vermin (I think), Carnage, and the monsters doppelganger Spider-Man from Infinity Wars teamed up in a very dark and evil storyline that I hated. It was a very atypical time in that comics history.
I vaguely remember that storyline. It didn’t stick with me too much. The first time Carrion appeared was pretty strong.
