Gaiomon

Gaiomon is a Dragon Man Digimon and a carrier of the X Antibody whose name is derived from "Triumphant King" (「凱王」), and whose design is derived from a Samurai-version of WarGreymon. It is referred to as "Samudramon" in Chinese Bandai products. Discovered within a neglected Oriental computer, it is one of the Greymon subspecies, which are exceedingly superior as "Combat Species" Digimon. It has won many battles and increased its strength, and while there are many parts of that strength which are unmeasured, it has been confirmed that it possesses an unbelievable combat record from its countless battles. Its uniquely shaped "Kikurin" (菊燐) swords, which it acquired due to its combat experience, leave behind eerie tracks of light, and it is said that anything which touches those tracks will be torn apart.

Digimon D-Cyber
Masuken was under the control of a MetalPhantomon in Chapter 2 and Hikaru receives a message from Masuken on his Digital Monster D-Cyber Version 1.0 to head North and find him at MetalPhantomon's lair. A battle ensues and Teru tells Hikaru not to argue with Masuken and that he wants to remain in the Digital World, believing Masuken that MetalPhantomon will give them power. Hikaru strikes Teru and tells him to wake up. In doing so, Teru is rendered unconscious. Masuken believes Teru murdered and orders his Digimon to come out, a Gaiomon. Hikaru's Digimon Death-X digivolves to a DexDoruGreymon in his grief and guilt. In trying to recover Teru, Hikaru realizes Masuken's trap and that the Teru before him isn't the real one, an illusion. Masuken switched the real one to anger Hikaru. Masuken tells his Gaiomon to kill him and send him to the "God of Death", but his Gaiomon is defeated by Hikaru's DexDorugoramon.
