Cult titles composed of compounds of nyx- are attested for several deities, most notably Dionysus Nyktelios "nocturnal" and Aphrodite Philopannyx "who loves the whole night". Roman authors mentioned cult practices and wrote hymns in the honor of their equivalent goddess Nox (Night).
Nyx, in Greek mythology, female personification of night but also a great cosmogonical figure, feared even by Zeus, the king of the gods, as related in Homer's Iliad, Book XIV.
From Khaos (Chaos) [Air] came forth Erebos (Erebus, Darkness) and black Nyx (Night); but of Nyx (Night) were born (Aether, Bright Upper Air) and Hemera (Day), whom she conceived and bore from union in love with Erebos.
Nyx is the Greek Goddess of the night, and the daughter of Chaos. She was told to be very beautiful. Her birthplace was not on Earth but in Gaia. She is Primordial God.
She was married to Erebus and had a number of children, including Nemesis (retribution), Hypnos (sleep), Thanatos (death), Geras (old age), Eris (strife) and Charon (the boatman who brought the souls of the dead to the gates of the underworld).
Nyx then later banishes his body and spirit. When Kalona was banished his brother Erebus took his place at Nyx's side as her protector, but he was never her lover or Consort. Nyx's one and only Consort was and is Kalona.
In Greek mythology and Roman mythology, Erebus (/ˈɛrɪbəs/; Ancient Greek: Ἔρεβος, romanized: Érebos, "deep darkness, shadow"), or Erebos, is the personification of darkness and one of the primordial deities.
It is commonly thought that Nyx is the only goddess that Zeus is truly afraid of because she is older and more powerful than him. This traces back to one story in which Hera, Zeus' wife and goddess of marriage and childbirth, works together with Hypnos, the god of sleep, to trick Zeus.
Nyx, sometimes referred to as "Mother Night", is the personification of night and a resident in the House of Hades. She gives counsel, directions and reviews the day's work of Chthonic Gods and staff, as seen in her interactions with Megaera, Dusa and the House Contractor.
That is to say, Nyx is one powerful god. A primordial entity of any mythology generally held gargantuan power over any other gods within the pantheon. To put Nyx's power into perspective, even the Olympian gods struggled with their predecessors from a mere generation before them for a decade.
I would say the three strongest in Greek Mythology are Chaos, Nyx, and Achlys. Chaos and Nyx are switched as The Creators of Everything depending on Myth. Achlys is considered older than Existence. Hence, they are the three oldest beings according to Greek Mythology, and they are generally considered the most powerful.
Hypnos was the son of Nyx (Night) and the twin brother of Thanatos (Death). In Greek myth he is variously described as living in the underworld or...
Nemesis – Another famous daughter of Nyx was Nemesis, the Greek goddess of Retribution. This was another daughter of Nyx who would work with Zeus, for Nemesis ensured that there was a balance to cosmos, where no man was supposed to be too happy or sad, or too lucky or unlucky.
PASITHEA was one of the younger Kharites (Charites) and the wife of Hypnos, god of sleep. She was probably the goddess of rest and relaxation.
Mamu (also transcribed as Mamud, ???) was a Mesopotamian goddess associated with dreams. She was regarded as the daughter of the sun god Utu and could herself be called the "Utu of dreams".
Aphrodite was the most beautiful of all the Goddesses. Aphrodite was the most beautiful of all the Goddesses and there are many tales of how she could encourage both Gods and humans to fall in love with her.
Naisula Gives Birth to Nyx.
Her mystic powers include telekinesis, regeneration, invulnerability, manipulation, and superhuman strength. Once, Hera convinced Nyx's son Hypnos to put her husband, Zeus, to sleep so she could plot against him. Zeus snapped out of it mid-collusion and gave chase to Hypnos. Hypnos sought refuge in his mother's cave.
Eris is the daughter of Nyx, or Zeus and Hera, and the sister of Ares, the Greek god of war, who she often accompanied into battle, riding alongside him in his chariot.
Shakti is one of the most powerful Hindu goddesses. She is even referred to as “The Great Divine Mother.” She is illustrated colorfully in art. She has multiple arms and their power in numbers is believed to hold a great force over humans.
Further, Odin is more durable than Nyx, which is no small thing. With Nosferatu he rarely has to spend a turn healing in Ch. 10, where Nyx almost certainly will sacrifice at least 2 turns she could use to attack to chug a vulnerary. Neither does Nyx double anything important that Odin doesn't.
Zeus is the strongest of the gods in the Ancient Greek religion because he has both power and intelligence. He is able to ensure that he is not replaced by another, more powerful deity. He is also able to ensure the allegiance of many other gods by giving them rights and privileges.
Hesiod says further that Nyx's daughter Hemera (Day) left Tartarus just as Nyx (Night) entered it; continuing cyclicly, when Hemera returned, Nyx left.
The figure could be an aspect of the goddess Ishtar, Mesopotamian goddess of sexual love and war, or Ishtar's sister and rival, the goddess Ereshkigal who ruled over the Underworld, or the demoness Lilitu, known in the Bible as Lilith.
Hades, Greek Aïdes (“the Unseen”), also called Pluto or Pluton (“the Wealthy One” or “the Giver of Wealth”), in ancient Greek religion, god of the underworld.
