Ilea was Hercules and Deianeira's only daughter. Ilea, along with her two brothers Aeson, Klonus, and their mother Deianeira, were killed by Hera when the goddess used a Fireball to destroy their home (HTLJ "The Other Side"). Hercules encountered Ilea and the rest of his family when he visited the Underworld to bring back Persephone. When the hero returned to Earth he asked Hades to erase Ilea's memories of the visit so she could continue to exist peacefully in the Elysian Fields (HTLJ "The Other Side").
- Ilea was played by Rose McIver.
- The name Ilea is an invention of the writers; Heracles's only daughter with Deianeira in mythology was named Macaria.
