Ra

Ra (also called Amun-Ra) is the god of creation, rebirth, and the sun. The first and greatest king of the gods, his being is divided into three different aspects with Khepri as the morning god, Ra as the day god, and Khnum as the evening god. Ra's greatest enemy and threat is the chaos serpent Apophis. He is an embodiment of Ma'at.

Background
Ra first emerged from the waters of chaos at the beginning of creation. He sailed across the heavens during the day and across the Duat during the night. As king of the gods, Ra's reign was the golden age of the earth.

When a prophecy was made that a child of Geb and Nut would supplant him as king, Ra forbade the pregnant Nut from giving birth on any of the three-hundred and sixty days of the year but the goddess was determined to see her children born and gambled with Khonsu, using the moonlight she had won to create five new days for her five newborn children: Horus, Isis, Nephthys, Osiris, and Set. As punishment, Ra commanded Shu to be a constant barrier between the earth and the sky, forcing Geb and Nut apart. Despite the treatment of his parents, Set would become loyal to Ra and serve as his chief defender against Apophis.

At some point in his rule, Ra imprisoned Apophis by using the spirit of Khepri to contain the demonic god. Unfortunately, this caused him to age and deteriorate as mortals do. Sensing his growing weakness, humanity began to turn against Ra who retaliated by sending Sekhmet to destroy them. The bloodthirsty goddess would drive humanity to the edge of extinction before a horrified Ra aided the magicians in stopping her. After Sekhmet's rampage, Ra chose Bast to succeed her as his champion.

Eventually, Isis desired the divine throne for Osiris and concocted a scheme to remove Ra from power. Creating the Tjesu heru to bite the wizened god, the venom's strength was such that no god's magic was powerful enough to heal him. Isis claimed that she could heal Ra but required his secret name in order to do so. Desperate, he agreed but was subsequently forced to abdicate by the goddess, fulfilling the prophecy of her birth. Before withdrawing to heaven, Ra tasked Bast with fighting down Apophis for eternity.

The Red Pyramid
Although Ra is not seen, his absence is significant in that Carter and Sadie realize that he must return in order to combat Apophis.

The Throne of Fire
Ra is first seen along with Bast and Isis in one of Sadie's visions of the past when Ra reveals his secret name and is forced to relinquish his power. Bes, Carter, and Sadie later find the present Ra in the Duat where he awakens in a demented state because only two of his three aspects had been restored. His third aspect is awakened after the Kanes combined forces with Desjardins to banish Apophis. However, Ra has still not fully been restored to his original powerful form as Khepri's essence has not yet combined with Ra's own. Despite this, he still retook the throne of the gods.

Personality
During his reign, Ra was described as a compassionate, honorable, and wise king. He traveled through the underworld nightly to bring warmth to the dead despite the inherent danger and only punished or sacrificed others when given no alternative. As noted by several of the gods, Ra gradually became more and more senile towards the end of his rule, giving Isis the opportunity to dethrone him. After his long exile, his mental deterioration is such that he behaves like a toddler. Despite this, it is shown that Ra is aware enough to recognize objects of significance such as Walt's curse and Zia Rashid's destiny.

Powers and Abilities
Ra is presumably the most powerful of the gods who is contested only by Apophis in might.

Relationships
Isis: Isis and Ra have an unpleasant relationship. It was Isis who banished him so that she and Osiris could take over. In addition, she also caused the god an enormous deal of humiliation by forcing him to reveal his secret name.

Set: Set is Ra's best lieutenant and a loyal god to Ra. Ever since Set heard Ra withdrew to heavens he began plotting his scheme to overthrow Osiris.In the celebration of Osiris, Set came and brought a box. Osiris then fell into Set box and Set boiled it. This results make Set the avenger from Ra.

In Mythology
The chief cult center of Ra was Heliopolis (called Iun or "Pillar", in Egyptian)[1], where he was identified with the local sun-god Atum. In mythology, Ra is the king of the gods and god of the sky. To the ancient Egyptians, he represented light, warmth, and growth making him an important god and ruling over all the other gods, humans, ect. Ra was thought to travel on two solar boats called the Mandjet (the Boat of a Million of Years), or morning boat and the Mesektet, or evening boat. These boats took him on his journey through the sky and the underworld. When Ra traveled in his sun boat he was accompanied by various other deities including Sia (perception) and Hu (command) as well as Heka (magic power). Sometimes members of the Ennead helped him on his journey, including Set who overcame the serpent Apep(a.k.a. Apophis) and Mehen who defended against the monsters of the underworld. Apep (a.k.a. Apophis), an enormous serpent Heka (magic spells) to stop the sun boat's journey every night by consuming it or by stopping it in its tracks with a hypnotic stare. In the evening the Egyptians believed that Ra set as Atum or in the form of a ram. The Mesektet or Night boat would carry Ra through the underworld back towards the east in preparation for his rebirth at sunrise. These myths of Ra represent the sunrise as the rebirth of the sun by the sky goddess Nut, thus attributing the concept of rebirth and renewal to Ra and strengthening his role as a creator god.

Trivia

 * In the Throne Of Fire, Ra kept talking about zebras and weasels. In the end it turned out that he was referring to Zia and Walt respectively.
 * In Throne of Fire it is stated that Ra is far more important and irreplacable than any other god or king. As the first god aside from being more powerful than others he is the Lord of Ma'at and essential to the survival of the universe. Akin, to how a plant needs sunlight to live, with Ra as the Sun which feeds the plant, while Apohis is the deadly Darkness if Ra was to die then The Universe like a sunless plant will slowly wither and die.
 * Ra is stated to be the "taproot" of the Egyptian gods and, by extension, the entire universe. Even if the others do not acknowledge it or possibly dont even know it as Isis presumely didnt know the consequences
