Ouryumon is a Dragon Digimon and a carrier of the X Antibody. It is an imaginary Digimon born from the "Daydream of a DigiCore". It is a form that had even the DigiCore's own creativity released through the Interface on its brow, and 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? lit. "Armored Dragon Left Greatsword"), and the right-hand sword is the "Gairyū Udaijin" (鎧龍右大刃? lit. "Armored Dragon Right Greatsword"). The blades of the wings on its back are called the "Gaiba Daimeijin" (鎧馬大名刃? lit. "Armored Horse Famous Blades"). The characters on its swords are their names. Together, its swords are called the "Gairyū Daijin" (鎧龍大刃? lit. "Armored Dragon Greatswords").
- Eiseiryuoujin (永世竜王刃 Eiseiryūoujin?, lit. "Immortal Dragon King Blade"): Fires an attack from the Gairyū Sadaijin and Gairyū Udaijin.
- Golden Armor (黄鎧 Ougai?, lit. "Yellow Armor"): Rampages like the earthflow of a mighty river, cutting everything apart while charging the opponent. There is a theory that Ouryumon's "Golden Armor" technique has its roots in Huanglongmon's "Oukai", although it is unconfirmed.

Official romanization given by the Digimon Reference Book and used in most of the franchise.
