This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Tepegoz (Azerbaijani)
In Turkic mythology, Tepegoz is a legendary creature who has only one eye on his forehead – a kind of cyclops. He is an ogre that appears in the Book of Dede Korkut, a famous epic story of the Oghuz Turks. Long ago, a nomadic herdsman of the Oghuz Turks saw a nymph who gave birth days later.
The herdsman finds the monstrous infant, a one eyed boy, and then flees. Bayandur Khan and Aruz decide to raise the strange creature. The creature is exiled as a boy after biting off another child's nose and ear. It lives in a cave and grows up to be a formidable threat to the Turks.
