Gaiomon

Gaiomon is a Dragon Man Digimon. Although his name lacks the prefix Grey, he is still a part of the Greymon-family as stated in his Japanese profile. His Japanese name Gaioumon comes from "gai" and "ou", which means armor and king in Japanese respectively. He is also called "Samudramon" in the Digital Monster D-Cyber Special Limited Edition.

He was discovered in an Orient computer. He has the appearance of a Samurai, and has two swords "Kiku Rin". He can shoot a spark from the swords. His appearance is reminiscent of the brave hero WarGreymon and his war record was a surprise when discovered, as it's similar to WarGreymon's.

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.
