Klonus is the older son of Hercules and Deianeira. Klonus, his brother Aeson, his sister Ilea, and Deianeira were all killed by Hera when she used a Fireball to destroy their home (HTLJ "The Wrong Path"). When Hercules visited the Underworld to bring Persephone back he encountered Klonus and the rest of his family living in the Elysian Fields. When Hercules returned to Earth he asked Hades to erase Klonus' memories of the visit so he could continue to exist peacefully (HTLJ "The Other Side").
