Zeus
Zeus is the sky and thunder god in ancient Greek religion, who rules as king of the gods of Mount Olympus. His name is cognate with the first element of his Roman equivalent Jupiter. His mythology and powers are similar, though not identical, to those of Indo-European deities such as Jupiter, Perkūnas, Perun, Indra, Dyaus and Thor. Zeus is the child of Cronus and Rhea. Zeus symbols are the thunderbolt, eagle, bull, and oak. In addition to his Indo-European inheritance, the classical "cloud-gatherer" also derives certain iconographic traits from the cultures of the ancient Near East, such as the scepter.Most of the time, Zeus is depicted as a grown man with a beard and longer curly hair, holding a scepter or thunderbolt and is sometimes accompanied with an eagle, his sacred animal. Sometimes, he is also depicted as a young man.
Chaos
Chaos, also known as Aer, was the first of the primordial gods to emerge at the dawn of creation. She was followed in quick succession by Gaia, Tartarus, and Eros. Chaos was the lower atmosphere which surrounds the earth - both the invisible air and the gloom of fog and mist. The word khaos means "gap" or "chasm" being the space between heaven and earth. Chaos was th emother and grandmother of the other misty essences - Erebus and Nyx. She was also a goddess of fate like her daughter Nyx and granddaughters, the Moirae.
Gaia
Gaia, or Gaea, was the divine personification of the Earth and the matriarch of all things in existence. She's often referred to as the Earth goddess, but she was more than that. She was the Earth itself. As one of the primordial deities, which were the first born gods and goddesses, Gaia was the very personification of the celestial body, which housed all of life. Since Gaia is the rawr, she sometimes is depicted as the earth or a woman made out of the earth. She can be dressed in earth or like it to. Normally she has brown hair and a green dress with vines and flowers on it.
Tartarus
In Greek mythology, Tartarus is the deep abyss that is used as a dungeon of torment and suffering for the wicked and as the prison for the Titans. Tartarus is the place where, according to Plato's Gorgias , souls are judged after death and where the wicked received divine punishment. Tartarus is also considered to be a primordial force or deity alongside entities such as the Earth, Night, and Time. Tartarus is monstrous in his physical form, standing at immense height, his purple glistening flesh rippling with muscle. His fingers are tipped with razor-sharp black talons. However, his most terrifying and distinguishing feature is his face- in place of a normal face is a swirling whirlpool and inward spiral of darkness, and his voice sounds like it is being drawn back inward rather than projecting outward.
Nyx
Nyx is the Greek primordial goddess of the night and hellhounds. She carries the mantle of night in her chariot pulled by two dark horses Shade and Shadow, covering the world with darkness. Nyx is one of the first beings to have sprung from the void of Chaos. Her Roman form is Nox. Nyx was described as a churning figure of ash and smoke, as big as the Athena Parthenos (which was 40 feet tall). Her face was hard to see except for the pinpoints of her eyes, which shone like quasars. When her wings beat, waves of darkness rolled over the cliffs. Her dress was void black, mixed with the colors of a space nebula as if galaxies were being born in her bodice.
