As a huge creature design enthusiast, I love me all the monsters out there whether they're influence by legend, mythology, fantasy, superstition, folklore or sci-fi origins.
Here's a pixel art interpretation of a Wendigo. I'm a huge fan of this folklore creature
Though last year I learned is a cultural Hollywood bastardization from native folklore. Originally it was said a greedy person corrupted by malicious spirits, driven to primal madness. But in modern entertainment era it is a dark-spirit corrupted person driven to endless hunger of human flesh. They're nowadays described as feral humanoids with deer or antler horns, growing dark fur and lost of any humanity.
