Who fought Cetus?

Who, I wonder, engaged in a mighty battle against the mighty sea monster Cetus? Was it a brave warrior, armed with a mighty sword and a heart of steel? Or perhaps it was a cunning strategist, utilizing wit and guile to outmaneuver this fearsome beast? The question remains, who was the valiant soul that faced Cetus, and what drove them to such a perilous encounter? Was it a quest for fame and glory? A desire to protect the innocent? Or simply a test of one's mettle, against a formidable foe? Whatever the reason, I must know: who fought Cetus, and how did they prevail?
