The Patasola or "one foot" is a shapeshifter in South American.
Description
The Patasola appears in the form of beautiful and seductive women to male hunters or loggers in the middle of the wilderness when they think about women, often in the likeness of a loved one. But in their true form, they would appear as one-legged freaks with ferocious vampire-like lust for human flesh and blood.
Behavior
Once they manage to lure their preys away from their partners deep into the jungle, they soon reveal their true, hideous appearance to attack, suck the blood and eventually devouring them.
