Name: Gerald Davidson

Gerald is not a symphogear user. He is a direct descendent of the oldest mythological hero, Gilgamesh and Gerald's powers are mainly inherited from him. Technically speaking, he is a complete asshole not unlike his ancestor before meeting enkidu and openly calls anyone else that is not himself or related to him as "Shit staining his presence".. Despite that, he still inherited his ancestor's wisdom to an extent.

Gerald has inherited nearly limitless strength from his ancestor. His capibilities includes (Shamelessly copied from TYPE MOON WIKIA):

Gate of Babylon: Treasury of the king

It is the golden capital, a storehouse type pocket dimension that house all treasures gilgamesh collected in his life, that was inherited by gerald. It connects the space of reality to the vault, opening an "invisible door" between dimensions that allows for the contents to pass through upon their owner's command.

It is a storehouse that contains the prototypes of every relics possessed by humanity, and the gate seemingly possess an infinity of relics in it, which are fired from golden portals at Gerald's will, fired carelessly as if he is throwing pebbles.

Gilgamesh is renowned for having collected all the treasures in the world in his lifetime, amassing a perfect treasury that lacked nothing. As there was nothing he was unable to collect, Gilgamesh was a collector of treasures, whose favorite phrase, "I collected all the treasures of the earth", is not a metaphor. As anything can be found within the vault, the amount of wealth within exceeds even his own knowledge; it is said that its inventory of treasure continues to increase even now.He collected and stored away samples of all the technology that was developed during his age. The desires of ancient humans were similar to those of the current age, so their technology, bolstered by the powerful magic of his era, was not inferior to that of the modern age. The "Instruments of Hope" that people dreamed of were all realized, and because every single case was requisitioned by the King's hand, his collection is even furnished with airplanes and submarines.

It also contains all of the original bases for all intellectual properties produced by mankind that originated in his kingdom, making board games and the works of the Library of Alexandria no more than imitations.That within are not merely riches, but his collection is the very "origin of human wisdom." It is the proof of human wisdom and human ingenuity.That which is missing from the vault would be items produced with completely new concepts by a new human race and items produced with extraterrestrial intelligence and technology. He is the original hero, so all heroes of various myths are derived from his legend. It may be a paradox, but he, as the original, must possess that which can be handed down as the Relics possessed by those later heroes for they are derived from him for that very reason.These weapons are technically nameless, the original Prototypes of the Relics (すべての宝具の原型, Subete no Hōgu no Genkei?) and merely common items before they became objects of faith that act as the foundations for their legends.

Each treasured weapon is decorated with dazzling ornaments and polished to a mirror-like shine, all clearly sporting the magical energy to define them as Divine Mysteries without exception. They are the original models of every legend, myth, and folklore.

The weaponry contained within includes swords, pole-arms, lances, hammers, shields, demonic swords that later made their way to Europe and South America, and a number of weapons , all of which form a perfect treasury of masses of unused weapons that simply went to sleep with the king. He owns the treasured swords that saved later heroes and the cursed swords that stole the lives of later heroes, and their numbers are approximately infinite. After Gilgamesh's death, the contents were spread all over the world after being passed on or stolen, and the treasures, valued because they were to become splendid swords and eventually Relics.

It states that the quality of the weapons makes the Relics used by others look like fakes themselves.

If weapons of a previous incarnation meet those that descended from them, such as Gram facing Caliburn or copies facing originals, the deteriorated newer model will always lose.

The only item contained in the vault that was not passed on to another user except his descendents than Gilgamesh is Ea, a sword unique to only Gilgamesh and Gerald, and the oldest and strongest relic created at a time before the creation of the planet.

Star of Creation that Split heaven and earth

Gilgamesh’s Ultimate Relic is Enuma Elish, an attack performed by unleashing Ea’s maximum output. Enuma Elish outright ignores any type of defense, be it physical, magical or divine defense, effectively ignoring any type of durability by showing the "Truth" of creation, creating a dislocation in Space-Time, ignoring all concepts and causality, effectively bypassing omnipotence and omnipresence, making it capable of killing even gods no matter how much high their dimensional existence is, and cutting their connection with any type of life or power sources they may have.

It signifies the birth of all creation, and blows away the very fabric of reality. Borne of the winds drawn unto the revolution of the three cylinders of Ea, a spatial severance is formed by use of the Sword of Separation. Compressed and intertwined stratifications of wind become a virtual dislocation of space-time, annihilating any who would stand in opposition.

Showing its power as an "Anti-World" weapon, it attacks everything in sight with a single strike. It cannot be said that what the blade cuts down is limited simply to "the enemy" as it is not a matter of aiming it, and it is impossible to even discuss as to whether it will hit its target or the practicality of the force behind it. Grinding at the laws of space with its power, it creates a rip in space that extends from not only the earth but also to the sky and atmosphere. It is a crack that distorts space to pierce the very nature of the World itself to show the "Truth." All that uses the cut space as a foundation is swallowed and crushed by the void, and the dazzling light only continues to grow as it continues to complete the destruction. Its use in a fight is not something that can be called a battle, but rather the wrath of nature itself.

Performing the miracle of genesis, something that reveals creation - the beginning of everything, the attack opens an abyss capable of crushing anything. The center of the storm is not calm, but rather a hole to hell itself that returns all that enters its realm to the nothingness from which it originated. The wind pressure creates a vacuum that takes all things with form, the land, the atmosphere, and the sky, into the whirling void. The tumult of genesis takes everything that was nothing more than chaos, which could not form any meaning, and creates a new truth that divides and distinguishes Heaven, Sea, and Earth. Within the darkness where everything is returned to nothingness, only Ea is left to shine with brilliance like a Star of Creation amidst the destruction, the first thing illuminating the new world.
