In Greek mythology, Sybaris was a dragon that terrorized the Greek city of Delphi. When the Oracle was asked how to stop it, it said to sacrifice a young man. Eventually, a demigod named Eurybaros, son of the river god Axios, was chosen, but he defeated the dragon by hurling it down Mt. Kriphis. A fountain is said to have emerged there and a city is said to be named after her.
The Titan Atlas makes skeletons with Sybaris' teeth, by growing them in a plant pot. The mortals thought the teeth were from a T. rex and put them in the T. rex's exhibit. When planted and watered (most likely with blood), unstoppable skeletons emerge from the ground, ready to kill.
