What are some stories of heroes saving the day?

The story of the hero's rescue: Greek mythology Perseus saves the king's daughter.

Perseus put on his flying shoes and invisible helmet and set off again, and in a short time came to the coast of Ethiopia, which was ruled by King Carpus. He saw a beautiful girl bound to a cliff, her large eyes weeping incessantly. Perseus looked at her, and a strong love welled up in his heart.

So he landed beside her and asked with concern what was wrong. It turned out that the girl was Andromeda, the daughter of King Carpus, because her mother Cassiopeia was proud of her beauty and thought she was the fairest of them all, a remark that made the sea goddesses angry, and they asked Poseidon, the god of the sea, to punish the king and queen.

Poseidon sent a sea monster as big and strong as a big fish to come up from the depths of the sea and ordered it to eat everything in the land ruled by Carpus. The priests told Carvus that to save the country, he must give his daughter Andromeda to the sea monster to tear and eat. So the people forced the king to lock Andromeda to a cliff by the sea.

Despite her fear, Andromeda had to stand at the foot of the cliff in heavy shackles, waiting in despair for the sea monster to tear her up. Before she could finish, the waves came rolling in and a sea monster emerged from the waves, opening its huge mouth and causing Andromeda to scream in terror.

King Carpus and Queen Cassiopeia also arrived. They were overwhelmed with grief and wept like mad as they wrapped their arms around their daughter. Seeing this scene, Perseus, son of Zeus, spoke up and said, "If you want to shed tears, there will be plenty of time for you to do so later, but right now you must hurry up and get your daughter out of there. I am the son of Zeus Perseus, killed the gore work demoness Medusa. Your daughters will surely agree to marry me if they can choose!

I now ask her to marry me, and if you say yes, I will save her. Not only did the king and queen agree to marry their daughter to him, they even promised to give him their entire kingdom as a dowry.
