Technically yes. She is the daughter of Zeus and Demeter. Poseidon was Zeus's brother.

Poseidon is Athena's uncle. Athena is the daughter of Zeus, and Poseidon is Zeus's brother.
In Greek myth, Perseus is the son of Zeus and Danae.
Posidon's brothers are Zeus(God of the Sky) and Hades(God of the Underworld)
Greek=zeus posidon hades Roman=jupiter neptune pluto
it was Zeus and people supporting him against posidon and people supporting him.
hades did not like his brothers. this is because they tricked him into becoming ruler of the underworld while they got the sky (zeus) and the seas and oceans (posidon)
Out of Zeus, Posidon, and Hades, I believe that Hades is the most powerful. Not only can he command all of the dead, but he has access to Tartarus. He could unleash all of the titans under oath that they would overthrow Olympus, slay Zeus and Posidon, and let him live. The titans could accomplish this feat with ease should they be released, and Hades is the one who can do that. Even if Zeus and Posidon both layed siege to Hades and his realm, Hades could hold them off with the dead for enough time to release the titans.
