Hygeia is the immortal daughter of the Asclepius, and Epione. She is the Greek goddess of good health, cleanliness, and hygiene.

An automaton of Hygeia acts as the guardian to Asclepius, and prevents anyone from seeing him. Leo turns her into "idiot-mode," making her attack herself, enabling Leo, Piper and Jason to get to Asclepius, but Asclepius says his real daughter Hygeia is very nice.


  • The word hygiene is derived from her name, as she is the goddess of cleanliness and sanitation.
