Calibos

Calibos was reportedly a son of the Goddess Tgetis. He was betrothed to Andromeda and supposed to inherite the throne of Cepheus. In this version the kingdom called “Joppa” instead of Ethiopia. However, Calibos was cruel and destructive. He hunted and annihilated every living creature in the vicinity of the Wells of the Moon. Including a herd of flying horses sacred to Zeus. An angry Zeus transformed Calibus into a satyr. The former prince was forced to live away from humanity, in swamps and marshes.  
 
Calibos however still wants Andromeda and abducts her. Perseus has to face Calibos in order to rescue her.
