Polyphemus was one of Poseidon sons.
Poseidon is the father of Polyphemus, the Cyclops encountered by Odysseus in Homer's epic poem, the Odyssey. Poseidon plays a role in Polyphemus' story when Odysseus blinds him, resulting in Poseidon's anger towards Odysseus for causing harm to his son.
Polyphemus responds to Odysseus with anger and violence after Odysseus blinds him. He curses Odysseus and his men, calling for vengeance from his father Poseidon. Polyphemus then blocks the exit of the cave, trapping Odysseus and his crew inside.
In Greek mythology, Poseidon is biased against Odysseus because Odysseus blinded his son, the cyclops Polyphemus. This act incited Poseidon's anger and led to his ongoing hostility towards Odysseus throughout his journey home from the Trojan War.
One major flaw Odysseus makes after escaping from Polyphemus is bragging about his feat while still within earshot of the Cyclops. This leads Polyphemus to call upon his father, Poseidon, to curse Odysseus and prolong his journey home.
See it isnt poseidons fault that his son became bad poseidon is technically father of all cyclopes if one of them turned out bad what could he do ? it isnt his fault that polyphemus turned into a bad cyclopes cyclopes are meant to be nice and help in poseidons work it is not bad for poseidon but it is bad for polyphemus
