Pongo

There are legends of this creature in Africa. He is said to have looked like a mix of a man and a monkey. Legend had it that the creature had magical powers and enjoyed the taste of human flesh. Female pongos turned into gorgeous women in order to get close enough to a man to eat him. Pongos and humans could reproduce hybrid kids who looked like normal humans, but had cannibalistic tendencies. In 1847, the pongo was amazingly discovered to exist. However, it is now called a gorilla and known to be a vegetarian. Okay, I admit this animal is obviously no longer a cryptid. However, it shows that reports of cryptids may sometimes be over-exaggerated, and if some are found to exist they may actually turn out to be pretty damn ordinary.
