Which mythical one-eyed being appears in The Odyssey (2026) premise?

Polyphemus is the mythical one-eyed being appearing in The Odyssey’s premise.

Polyphemus is a Cyclops, a giant creature with a single eye, encountered by Odysseus during his long journey home from the Trojan War. In Homer’s Odyssey, Polyphemus is the son of Poseidon and traps Odysseus and his men inside a cave before Odysseus devises a plan to escape.

The 2026 film adaptation follows Odysseus’s voyage and specifically mentions encounters with mythical figures including the Cyclops Polyphemus, sirens, and the nymph Calypso. The answer is therefore a named character from the premise, not a general category such as “Cyclops.”

The alternatives belong to other mythological traditions or episodes. Cerberus is the many-headed hound guarding the Underworld, the Minotaur is the bull-headed inhabitant of the Cretan labyrinth, and Charybdis is a deadly sea hazard associated with Odysseus’s voyage—but she is not the one-eyed being. Polyphemus is the distinctive single-eyed figure.
