Pelias (uncle), Aeson (father), Polymede (mother)
|First appearance:||Jason and the Argonauts|
In Greek mythology, Jason was the son of Aeson (the rightful ruler of Iolcus). Pelias (Aeson's half brother) was power hungry, so much, that in fact, he stole the throne from his brother and became the king of Iolcus. When king Aeson died, Jason went back to reclaim his throne. But Pelias' oracle told him that his nephew would one day overthrow him, so Jason sent him to fetch the Golden Fleece of Colchis. Jason called Hercules and his servant Iolas, Atalanta, Prince Meleager, Orpheus the son of Apollo, Castor and Pollux, Zetes and Calais, and King Peleus of Aegina.
