Mars/Ares about the katoblepones, in The House of Hades

Katobleps (pl. katoblepones), also known as Catoblepas, is a cow monster whose name means 'down-looker'.

The Heroes of Olympus

The House of Hades

The katoblepones were accidentally imported to Venice, Italy from Africa. They eat poisonous roots that grow by the canals and have a poisonous gaze as well as poisonous breath. Frank Zhang destroyed all of them in Venice, which gave him the power of turning his enemy into a snake. He used the power to turn the last katobleps into a snake.
