Orochi (Warriors Orochi)

Orochi (遠呂智) is an alternative spelling for a supernatural serpent. This particular serpent refers to the famed eight-headed serpent of mythology, Yamata no Orochi. It feasted on the flesh of young maidens in Izumo until Susano'o tricked and killed it. The tail of the beast held a treasured sword. Being the titular antagonist of the Warriors Orochi series, he is the last boss for all story modes (except for the Orochi story mode in the second game). Orochi is unlocked in the first installment once every other character is available. He also has a character image song titled Muken Kodoku; it is a vocal version of his theme song in the series.

His secondary version in this series is referred to as Orochi X (真・遠呂智, Shin Orochi, lit. True Orochi) and is counted as a separate character from his default model. To unlock Orochi X, players must complete all stages in the game including those found in Dream Mode. He has no personal image section in the Gallery Mode and has no other alternate costumes. Both forms of Orochi can be unlocked in the third title by viewing all of the game's endings. On the fourth title, Orochi and his secondary form can be unlocked through a special camp upgrade.

Yamata no Orochi appears without major alteration to its mythical depiction in Nobunaga no Yabou Online, Toukiden 2, and Nioh. The Black Dragon is also said to be an incarnation of the mythological creature in Harukanaru Toki no Naka de 4.
