Poseidon is God and ruler of the seas. He is the most impulsive one and more relaxed out of his brothers, Zeus and Hades. Poseidon is often the source of humor, and although reckless, he cares for his family very much. Poseidon is a member of the 6 Traitors Dynasty.

Poseidon can often be a little dense, and not pick up on what everyone already knows and he is also known to be very impulsive. For instance, when the three brothers go out for brunch, the waitress recollects that Poseidon caused all the tanks to crack and break and release large waves of water all over the building. Poseidon also loves mermaids and gazes at them often. This is not to say he is devoid of wisdom, especially when it comes to relationships. During brunch, he pointed out to Hades that having an emotional affair could be just as bad as one based on physical intimacy.
