Ophiotaurus

Ophiotaurus (Greek: Οφιόταυρος, meaning Serpent-bull) is a hybrid creature from Greek mythology.

Myths and Legends
It described as part bull and part serpent, and the creature's entrails (insides) were said to grant the power to defeat the gods to whoever burned them. The hybrid was slain by an ally of the Titans during the Titanomachy, but the entrails were retrieved by an eagle sent by Zeus before they could be burned. The creature emerged from Chaos with Gaia and Ouranós.
