|Portrayed by||Karl Johnson|
Itheus is the father of Demetria.
Itheus came to find Demetria in the City of Atlantis, but discovered she was missing from her work at the palace. He came to Jason, Pythagoras and Hercules for their help to find her. He was overwhelmed by the stress that he suddenly fell ill and was forced to rest in Hercules' Home until the party returned.
When they finally returned, Itheus heard from Medusa that Demetria had travelled back to Helios because of a boy. He was pleased by this and decided that he was ready to die. (A Girl By Any Other Name)
