Ouryumon

Owryumon is a Dragon Digimon and a carrier of the X Antibody whose name and design are derived from the Promoted Rook (竜王). It is an imaginary Digimon born from the "Daydream of a DigiCore". Due to the interface on its brow, even its DigiCore's own creativity was miraculously released, and its form digivolved. Possibly because it naturally possessed the ferocious combat data of the "Dragons" and "Generals" of Japanese myth within its DigiCore, the form created by its DigiCore is a "Warrior Dragon", clad in frightening, majestic Japanese armor and holding swords in both of its hands. The left-hand sword is the "Gairyū Sadaijin" (鎧龍左大刃), and the right-hand sword is the "Gairyū Udaijin" (鎧龍右大刃). The blades of the wings on its back are called the "Gaiba Daimeijin" (鎧馬大名刃).

Digimon Chronicle
OwRyumon is the Mega form of Ryudamon, the partner of Yuuji Musha. He faces of against Gallantmon of the Royal Knights and wins. However he is unable to stand up to the power of Gallantmon X and is defeated. He later assists Alphamon against Dexmon and eventually gives him his power to become Alphamon (Ouryuuken) in order to take down the undead menace.

Digimon D-Cyber
Masuken's partner is originally a Gaiomon, but is defeated by Hikaru's DexDorugoramon. It reverts into a Digi-Egg, and temporarily becomes a DexDorugamon through Death-X Evolution. Finally, it is revived as a Ryudamon. Ryudamon eventually becomes a Hisyarumon, and after receiving power from the Holy Knights, gains the ability to become Owryumon. Then, finally, Owryumon becomes the blade that allows Alphamon (Ouryuuken) to destroy Dexmon.

Attacks
 * Eiseiryūoujin (永世竜王刃): Fires an attack from the Gairyū Sadaijin and Gairyū Udaijin.
 * Golden Armor (黄鎧): Rampages like the earthflow of a mighty river, tearing everything to pieces while charging the opponent. There is a theory that Owryumon's "Ougai" technique has its roots in Fanglongmon's "Oukai", although it isn't confirmed.
