Great Sword Aegaeon

Great Sword Aegaeon is the weakest of Pallasites First Class.

Appearance
Aegaeon is an adult male rugged appearance. His hair is blue and is divided into two divisions by a midline center, from which arise tufts of hair falls outward. His eyes are a light shade between green and blue, and emphasizes its prominent chin reminiscent of Dohko.

First Fight Again Ikki
It is not known precisely for what reasons Aegaeon fought Ikki. Only it is speculated that he was ordered to stop Phoenix Ikki to know he was watching the Supreme God (Figure yet unrevealed, which is higher than Pallas), or both of them may have an ancient rivalry.

Pallas Castle
He appears along with Gallia and Hyperion on Pallas and Titan. He is presented as a user of the Great Sword Jūbakuraizanba. Together with other Pallasite First Class, Aegeon discusses the possibility of an immediate attack against Athena.As Hyperion and Gallia, Aegaeon seems to be totally subordinated to Pallas. He says he wanted to have a duty of care Goddess.

Battle Of Pallas Velda
When Mira finds  bronze saints Aegaeon feels the presence of Ikki reaching the battlefield and confessed to having sent an expedition of Pallasites soldiers to kill him.

Then he remembers the power of the Phoenix Bird that even having been wounded in the shoulder, managed to crack his powerful Great Sword Jūbakuraizanba. Later, he and Titan speculate that nothing could stop the Bronze Saints, so he learns that only the so-called Gate of Time is that it has the power to halt the advance of the defenders of Athena.

Fight Againts Bronze Saints
Later, everyone gathers in the throne room where the Pallas has absorbed enough of her sister cosmo to advance to the appearance of Pallas, and it is able to demonstrate what surprises cosmo Aegaeon and his companions. He later fought Koga and friends and overwhelmed easy but got suprised when koga placed a crack on his sword.

Second Fight Againts Ikki
He then fought phoenix ikki. At first he had the upperhand in his fight against Ikki, until ikki broke his holy sword. Phoenix ikki then used the Genma Ken technique to try and make Aegaeon reveal who his true master was. Aegaeon however, managed to counter by hitting himself with the hilt of his sword. They both fought until Ikki and Aegaeon clashed cosmos. Realizing that they would kill each other off if they continued, Ikki sacrificed his life to take Aegaeon with him.

Trivia

 * Aegaeon is the name of one of the Hekatonkheires, a race of 3 giant creatures that had 100 arms and 50 heads each. The Hekatonkheires were children of Gaia and Uranus, and the younger siblings of the Titans. However, Uranus was fearful of their power and disgusted with their appearance, so he shoved them back up Gaia's womb and imprisoned them in Tartarus. They were later freed by Zeus in return for their aid in the Titanomachy, during which they threw mountains at the Titans. After the Titans were defeated and jailed in Tartarus, Aegaeon's brothers serve as their guards, while Aegaeon himself works as Zeus's attendant.
 * Aegaeon is the name of one of Saturn's moons.
