Acrisios was worried that his grandson was going to kill him but he prevented this by locking his daughter away.
Zeus, the God of thunder, was watching Acrisios's daughter but Zeus turned himself into golden rain that impregnated her. Nine months later, she gave birth to Percues.
My king, I have something for you.
Yes, what is it ?
Acrisios found out that his daughter escaped so he took his daughter and grandson and put them in a chest and left her at the middle of the ocean when a fisherman found her and took her to his king, Polydectes.
I must kill you!
As Persues grew up, Polydectes put him through challenges, like to kill a snake-haired women named Medusa.
What are you doing here?!
Persues started to think about his grandfather so he sailed to see him but Acrisios was worried that the prophecy was coming true.
Persues made it to the island and attended a festival. He played in a disc contest and while throwing a disc, he lost control, killing his grandfather.
