Loogaroo
The Loogaroo haunts the off the coast of North America, in the West Indies, specifically Haiti, Grenada and the Dominican. It’s a take on the french monster “Loup Garou” which is a werewolf. The Loogaroo is more of a shapeshifting witch/wizard that can take the form of other monsters, and goes around sucking blood. It’s basically an amalgamation of all the monster myths out there. The blood it takes, it offers to the devil for more power, and if it takes too much from you, you’ll become a Loogaroo yourself.
