Leodes

Leodes, a diviner, was a minor suitor of Penelope. He had darkly predicted that Odysseus would return to avenge the suitors' abuse of hospitality. He was the last person whom Odysseus killed in his homecoming rampage, decapitated while pleading for his life:

Leodes rushed in and caught the knees of Odysseus, and spoke to him in winged words and supplication: 'I am at your knees, Odysseus. Respect me, have mercy; for I claim that never in your halls did I say or do anything wrong to any one of the women, but always was trying to stop any one of the other suitors who acted in that way. But they would not listen to me and keep their hands off evil. So by their own recklessness they have found a shameful death, but I was their diviner, and I did nothing; but I must fall, since there is no gratitude for past favors.'
Then looking darkly at him spoke resourceful Odysseus: 'If you claim to be the diviner among these people, many a time you must have prayed in my palace, asking that the completion of my sweet homecoming be far off from me, that my dear wife would go off with you, and bear you children. So you cannot escape from sorry destruction.'
So he spoke, and in his heavy hand caught up a sword that was lying there on the ground where Agelaos had dropped it when he was killed. With this he cut through the neck at the middle, and the head of Leodes dropped in the dust while he was still speaking.
