Heracles was half man half god. His mother was a moral and his father was a king- the king of all gods, the mighty Zeus. Hera was jealous from the start because Heracles was half god and she was just a moral.
Do these 12 labors.
Hera tried many ways to kill her own son. She even tried to kill him with snakes, but he was to strong.
Can be a moral?
Zeus sent away his son to live on earth with a family because he feared that Hera would eventually find a way to kill Heracles.
A few years later, Hera found him and his evil cousin. Hera and Eury (the cousin) teamed up to kill heracles. They gave him 12 labors to do ;1 of them will surely kill him.
After Heracles completed the 12 labors, he asked the Oracle at Delphi if he could be a moral.
In the end Heracles had great adventures, discovered true friends and rid the world of nasty critters.
