Big Three

zz The Big Three is a collective term which refers to the gods Zeus, Poseidon and Hade

The Big Three
The Big Three are the three most powerful gods in all of Olympus: Zeus, God of the Sky, Hades, God of the Underworld, and Poseidon, God of the Seas. The Big Three are equally matched in power for the most part, with Poseidon commanding the seas which cover most of the Earth, and Hades being the God of Underworld, representing every person who has ever died and now is a ghost. Despite Poseidon and Hades' large power, Zeus commands the sky which covers the entire Earth, but has few inhabitants, and even fewer are sentient, while Poseidon and Hades have many more creatures in their domains both non-sentient (fish) and sentient (the dead and mermaids).
