Answer:
I don't know if this is a story that you make up, but here you go:
It was years later after Theseus became king. He was noble and wise; caring for his people with such wisdom and power. Everyone admired his cunning character. All except King Minos of Crete, who was outraged to have his daughter married to Theseus without his permission. Not only that, but his tribute over the death of his son hadn't been payed for years.
"I must find a way to kill of Theseus!" he muttered to himself one lonely afternoon. "And once I do, I could take over his land and rule it myself!"
The details played in his mind all night. At last, he ordered his soldiers ready for battle. Having hundreds of his best men onto large, wooden ships to take over the land for their king.
Theseus, as strong and wise he was, was not prepared for this. His people were screaming in the streets of the grand city. Children and women alike were slaughtered without mercy. Outraged, Theseus ordered his soldiers to help defend the city. He himself dressed up in armor to assist his warriors. For those who were not able to fight and had children, were ordered to take shelter in the castle.
Came the moment Theseus confronted King Minos, he demanded, "What is the meaning of this open rebellion?"
"I have come to take revenge on you for taking my daughter from me," King Minos announced. "She was my dearest treasure, and you have taken it from me. I demand she be send back to me."
"You don't deserve her," Theseus snapped.
Minos roared in sudden, raw rage. "Then I will have your head!"
The two kings lashed out. Battle around them was raging; the streets were in chaos. The war lasted for almost an entire day. Theseus and Minos had begun to battle near the rocky cliffs by the shore. They were tired and sore, yes. But neither of them were too keen on giving up fighting for what they cared for dearly. Theseus, however, had an advantage. Aside from his courage and wisdom, he was much stronger and younger than King Minos. The wheels in his mind began to turn.
They were both near the edge of the cliff when Theseus spoke out: "Alas, there she is! In the water!"
Minos spun around, terrified for his daughter. But no, there was nothing there. Theseus kicked his foe with enough force and power to send King Minos over the edge, sending him to his death. With him now gone, the battle had ended. And there was no one else who dared face Theseus's wrath ever again.
THE END
All it takes is just a bit of creativity. I hope this helps :)
