Slippery pale naked humanoid creatures in the dark

The mother (barbarian movie)

Gollum (lord of the rings and the hobbit)

“Slippery naked guy”/descendants (uncharted 1)

Those big dick naked guys from outlast 1

The cannibals (Bone Tomahawk) (I was genuinely surprised by how good this movie was. Truly unexpected how terrifying the cannibals were when they were finally revealed.)

Scp - 096 aka shy guy (myriad of fan made arts and short films)

I love horror aspects in all forms entertainment and the pale skinny naked figure in the dark has always been terrifying for me.
