Who is pasidons brother?

Pasidon, commonly referred to in the context of Greek mythology, is likely a misspelling or variation of "Poseidon," who is one of the twelve Olympian deities. Poseidon's brothers are Zeus, the king of the gods, and Hades, the god of the underworld. Together, they divided the realms of the world among themselves after overthrowing their father, Cronus. Poseidon became the god of the sea, earthquakes, and horses.
