Bigfoot (Abominable)

Bigfoot is the main antagonist of the bloodthirsty horror movie known as Abominable - despite being based on Bigfoot the movie completely changes the cryptid's personality, as the real Bigfoot is believed to be a peaceful being (unless provoked) : instead it seems to have the personality of the Yeti, a far more dangerous and aggressive ape-creature from Himalayan myths.

It is likely Bigfoot was chosen so as to allow the movie to be set in America, with the creators either deliberately making it more like the Yeti or simply deciding on a homicidal take on actual Bigfoot lore (much as horror movies do when making twisted takes on other folkloric characters like Santa Claus or the Tooth Fairy).
