He took part in the Argonautic excursion and freed Hesione, daughter of the Trojan king Laomedon, from a sea monster.

In Libya he defeated the giant Antaeus, son of Neptune and Earth, who was very strong, because he got his strength by stepping on the Earth, his mother's body.

He brought Alceste from Hades, after she fought with Charon and freed her. Alceste was the wife of the king of Feres, Admitos, who, in order to save her husband, agreed to die in his place. Hercules happened to be passing by Feres in those days and stopped by to visit his friend the king. Learning of the great calamity that had befallen his palace, he ran and, catching up with Charon, fought with him and brought the beautiful Alceste back to life.
He freed Theseus from the prison of the king of the Molossians in Epirus.
Hercules' last feat was the murder of the centaur Nessus, who tried to steal the hero's wife, the beautiful Dhinera.
