Orochi/Story

Past
Orochi is a divine being who calls itself "Gaia's Will". It was supposedly born from the earth itself, manifested through floating emotions and substances of nature. Orochi's main power is "nothingness", implying that the god has no distinct gender. It is hinted to be the equalizing force between humans and nature. Since ancient times, Orochi was nature's guardian and was granted with many of its powers. It gained followers to its cause and eventually formed a clan. The eight strongest warriors were known as the Hakkesshu. As mankind began to grow in numbers, however, the natural balance began to crumble.

1800 years ago, Orochi could no longer tolerate the destruction as a byproduct of human progression and wanted to completely wipe humanity from existence. It used the powers gained from nature purely as a tool for chaos. Its clan and the human race waged war until the Kusanagi, Yata, and the Yasakani defeated it with three mystical treasures. The Hakkeshu and Orochi were defeated and sealed. Though kept in a suspended state, Orochi continues to feel that mankind pollutes the world.

Orochi Saga
Orochi's loyal servants continue to work to break its seal until Orochi is able to break free from it. In The King of Fighters '97, Orochi possesses Chris's body and wants to continue its previous desire to cleanse the world. The three sacred treasures work together to defeat it and seal it away.

Tales of Ash
By The King of Fighters 2003, a group of servants of another deity created by Gaia broke the Orochi seal. They are known as Those from the Past, and plan to take Orochi's power for their master, Saiki. Ash Crimson steals two of the three sacred treasures for seemingly this purpose, but in the end betrays them during the climax of The King of Fighters XIII. Once Ash disappears from the present, the treasures are restored to their rightful owners.

The King of Fighters XIV
In The King of Fighters XIV, Orochi's soul was residing within Verse. After Verse is defeated, Orochi lands in Hungary, but cannot maintain itself without a catalyst as Chris was resurrected in a new body elsewhere. It is found and sealed once again by the three sacred treasures.

The King of Fighters XV
Chizuru Kagura senses a totally different anomaly involving Orochi. The seal is intact, but there are strange happenings that she describes as a total change, that involves this serpentine entity. Moreover, four of its heralds, the Hakkesshu, has been revived, and is seeking to once again break the seal holding Orochi at bay.

However, the seal holding Orochi remains intact despite the interference of Verse, Re Verse and Otoma=Raga.
