The hero known for defeating the Cyclops is Odysseus. In Homer's "Odyssey," he cleverly escapes from the monstrous one-eyed giant by using his wits rather than sheer strength. Odysseus tells the Cyclops his name is "Nobody." After blinding the creature, when it calls for help, other Cyclopes hear, "Nobody is hurting me," and come to aid. This encounter showcases Odysseus's intelligence and resourcefulness, reinforcing themes of cunning over brute strength in overcoming obstacles and achieving one's goals.
