Poseidon

"The sea does not like to be restrained."

- Poseidon

Poseidon, also known as Neptune, is the God of the Sea, Storms, and Earthquakes from Greco-Roman mythology and ruler of the underwater kingdom of Atlantis. He is an Elder Olympian, son of Kronos and Rhea, and is a founding member of the Twelve Olympians and Mount Olympus.

Overview
"The mighty monarch of the seven seas and the absolute ruler of all sea monsters."

- The Infernal Compendium

Poseidon was the god of the sea, oceans, storms and earthquakes and also one of the twelve Olympian deities of the pantheon in Greek mythology. His main domain was the ocean, and was called the "God of the Sea". Additionally, he is referred to as "Earth-Shaker" and "Storm-Bringer" due to his role in causing earthquakes and storms, and has been called the "Father of horses" as he created them from sea foam.

He is usually depicted as an older male with curly hair and beard. Poseidon is married to the sea goddess Amphitrite and together they had a son named Triton. Like Zeus, Poseidon has had numerous affairs and thus many children but unlike his brother's vengeful wife Hera, his own wife did not press the matter. He also had a child with Aphrodite, a daughter named Rhodos. Other notable children of him were the hero Theseus, the hunter Orion and the cyclops Polyphemus.

Linear B tablets show that Poseidon was venerated at Pylos and Thebes in pre-Olympian Bronze Age Greece, but he was integrated into the Olympian gods as the brother of Zeus and Hades. There is a Homeric hymn to Poseidon, who was the protector of many Hellenic cities, although he lost the contest for Athens to Athena. Like his brother, Zeus, Poseidon has fathered numerous children and is quick to punish those who have "wronged" him.

The name of the sea-god Nethuns in Etruscan was adopted in Latin for Neptune in Roman mythology: both were sea gods analogous to Poseidon.

Appearance
Poseidon appears as a handsome young man in his early 20s with a muscular body befitting that of a swimmer. He has black, spiky hair that is close-shaven on either side of his head and has a single bang falling down on his forehead, as well as two blue streaks running upward at the front. He has thin and sharp eyebrows that curve upward toward his temples and level out past the top of his ears.

He wears a blue jacket with a furred collar over a dark shirt emblazoned with an animal skull, as well as a pair of black fingerless gloves with a backwards-pointing metal spikes attached to a ring on each finger and thumb gray pants with a sweater tied around his waist, and black sneakers inscribed with an X on the tongues. He also keeps a blue mask tied around his left elbow, which is decorated with the visage of the lower half of a skeleton's face with a filter on either cheek, and when worn, the jaws move in accordance with his own mouth movements.

When he first appeared, he was an extremely muscular elderly man with a mustache and a beard. He wore nothing but a crown on top of his head, wielding his signature trident in his hand, and a simple white fundoshi.

Personality
Poseidon is, in overall, a benevolent god and shares many characteristics with his younger brother Zeus, including pride, stubbornness, and a fearsome temper. However, he appears to have matured and mellowed out over the millennia, to the point where these attributes don't dominate him as much as they do to his brother anymore, making him more reasonable.

He has a fairly easy-going and laid-back personality, though when it comes to his duties as a god, he is very dedicated and diligent with his works, to the point where he would stay up for months non stop to finish his paperwork. Because of this, he often severely lacks sleep and can't fall asleep everywhere and everytime.

He is very environmentally conscious, feeling extremely disappointed and annoyed when it comes to humanity's pollution of the seas and other water sources. Often, he would curse humans who litter the seas with minor inconveniences, though when he is particularly pissed, he would summon forth tidal waves to create immense destruction to human establishment.

When he falls into a depressed state, he can be even more dramatic than Zeus and Hera combined, as noted by his family. When he failed to woo Amphitrite, he became extremely depressed and pointlessly wandered over the seas, bellowing his sadness and misery to anyone to hear, giving other gods and sea creatures terrible migraines.

He has a very particular sense of humor, sometimes making it extremely difficult to tell whether he is joking or not. He also has a habit of toying with his siblings, which had earned him the annoyance of Zeus multiple times, even almost causing a world between their realms as a result.

He cares deeply about his family, especially his children, as Azazel - his adopted father - had stated that this is his fatal flaw. When Odysseus blinded his son Polyphemus, despite being one of his least favorite children, he still cursed the Greek hero's life with misery for hurting his son even though it was to save the lives of him and his crew. It is said that when the possibility of harming Percy's life came up during a Solstice meeting, he had threatened to rain disaster upon disaster upon America until it became a wasteland if a single hair on his head was hurt. He also cares alot about his descendants, as shown through his interactions with Nezha and Frank Zhang, seeing them as his (many times great)-grandchildren.

Despite his positive traits, it is noted that he is one of the most vengeful gods in the entire pantheon. When queen Cassiopeia claimed to be far more beautiful than the Nereids, he ordered the sea monster Ceto to terrorize her kingdom, and even though he did allow his nephew Perseus to slay it and save the kingdom afterward, he still hanged Cassiopeia by her ankle on the sky eternally as punishment for her insolence. Perhaps the most well-known example of his vengeful rage occurred after Minos refused to appease him by sacrifice the white bull he had previously sent, which led him to possess the body of said bull and raped Minos' wife Pasiphaë as a result, leading to the birth of the fearsome Minotaur.

Roman Form
Poseidon can change into his Roman counterpart of Neptune. As Neptune, he becomes more disciplined, militaristic, and warlike than his Greek counterpart. For Greeks, he was a major civic god and was highly respected for being the god of the sea and earthquakes. However the Romans, who were not seafaring people, associated him more with fresh water and horses, and treated him with a fearful respect.

Harming, Trapping, & Banishing

 * Witchcraft: As witchcraft is a form of magic wielded by witches to oppose those of heavenly nature, pagan gods such as Poseidon are susceptible by witchery. There are many witchery spells and rituals that can be used to trap, weaken, and hurt him, with some rituals rumored to be capable of even killing immortals such as the pagan gods.
 * Celestial Weapons: Weapons made out of sacred metals, such as Celestial Bronze or Imperial Gold, can be used against the majority of supernatural beings, including pagan gods such as Poseidon.
 * Lack of Worship & Offerings: As a pagan god, Poseidon gains more power from the prayers, offerings, and sacrifices from mortal devotees, and is dependent on it to maintain his immense divinity. If he stops gaining offerings from his loyal followers, his powers may become immensely weakened. Due to his essence being tied to the Western Civilization, he can gain power from those associated and symbolized by his divine domains, or associated with him or the myths surrounding him.

Killing

 * Divine Weapons: The divine weapons of the gods, which are crafted from sacred metals and are imbued with their wielders' divinity, can be used to kill or injure fellow immortal gods like Poseidon. However, due to his immense power, only a chieftain god’s Symbol of Power is capable of killing him.
 * Enochian Weapons: Poseidon can be killed using weapons made out of Enochian metals.
 * Longinus: As the Longinus are Sacred Gears made out of Enochian metals of the highest-ranking, forged by Heavens' forges with the highest-quality Enochian technology and are imbued with fragments of the Biblical God's divinity, those with enough skills and experience can absolutely and permanently killed Poseidon, to the point where he can never be reborn or resurrected again.
 * Faustian Weapons: Poseidon can be killed using weapons made out of Faustian metals.
 * Primordials' Weapons: Weapons created and wielded by primordial entities can be used to permanently and absolutely obliterate every and any being in existence but other primordial entities, erasing their entire existence from the worlds so that they can never be reborn, or resurrected again without being saved by God's omnipotence.

Trivia

 * Poseidon and Apollo are the only two major Olympians who have temporarily been stripped of their divinity and godly powers.
 * After many competitions with other Olympians, Poseidon finally became the patron god of Corinth and Mantineia.
 * Due to him helping raised Persephone alongside Demeter, she thought of him more as a father than Zeus, her actual father, can ever be.
