Dorumon (Chronicle)

Dorumon is Kouta Doumoto's Digimon partner.

Digimon Chronicle
When Kouta attempted to protect Dorumon from Okuwamon, Dorumon became Dorugamon for the first time. Later as Dorugoramon he was able to defeat the Royal Knight Omnimon in battle. However Omnimon became Omnimon X and was able to beat Dorugoramon close to death. This caused him to Death-X Digivolve into DexDorugoramon as a result of the X-Antibody being present. However Yggdrasil removed DexDorugoramo's digicore. Dorumon was restored in a new body but his now coreless body (akin to a souless body) digivolved into Dexmon. The Royal Knights attempted to destroy the undead menace but were unable to (Even Omnimon X's All Delete failed to destroy Dexmon). However, Dorumon was able to digivolve first into Reptiledramon, then Grademon and finally Alphamon. Alphamon and Owryumon (the Mega form of Ryudamon, partner of Yuuji Musha) battle Dexmon together but are unable to defeat him but they combine their powers as Alphamon Ouryuken who defeats Dexmon. Afterwards they and their partners make a compromise with Yggdrasil, where the X-Antibody Digimon are merely reverted back to their normal forms (e.g. WarGreymon X became a normal WarGreymon), instead of being annihilated.
