Hercules was the son of Zeus. Zeus came in the figure of Alcamena's wife, Amphitryon and they had two children.
Hera, Zeus' wife,was jealous and sent two snakes to kill Hercules and his younger brother but what she did not know was that Hercules had super strength .
Hera put Hercules through tough trials against many beasts because she wanted him dead but always ended up victorious.
Soon Hercules was granted a wife after defeating the Minyans. He had three children and loved them dearly. At this point Hera was infuriated and put Hercules into a blind rage which resulted in the deaths of his three children and wife.
