Menoetius (Greek mythology)
A son of Iapetus and Clymene or Asia, and a brother of Atlas, Prometheus and Epimetheus, was killed by Zeus with a flash of lightning, in the War of the Titans, and banished to Tartarus. His name means "doomed might", deriving from the Ancient Greek words menos ("might, power") and oitos ("doom, pain"). Hesiod described Menoetius as hubristic, meaning exceedingly prideful and impetuous to the very end. From what his name suggests along with Hesiod's account, Menoetius was perhaps the Titan god of violent anger and rash action.
Guard of the cattle of Hades
During Heracles twelfth labor, to steal the hound Cerberus, he slays one of Hades cattle. A certain Menoetius, son of Keuthonymos, challenges Heracles to a wrestling match during which Heracles hugs him and breaks his ribs before Persephone intervenes.
