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.
