Poseidon

This website discusses Poseidon who is Zeus's brother.

These are excerpts from the website. I thought these two paragraphs told the reader the most about Poseidon.

Poseidon was powerful, decisive, competitive, and dignified. It was very important to stay on his "good side", for he was also moody and irascible, quick to take offense, and made a hobby out of taking his revenge out on those who angered him.

After Poseidon and his brothers and sisters defeated the Titans and dethroned their father Cronus (Kronos), the Greek gods held a lottery to determine which of the realms each would rule. Hades drew the Underworld, Poseidon won the oceans, and Zeus got the heavens, making him the supreme ruler. They agree to all share the power over the earth, though the greatest responsibility for it went to Poseidon.

The trident is the symbol he is most known by.
