Alphamon

Alphamon is a fictional character from the Digimon franchise, the Mega form of Dorumon. He is not just one of the 13 Royal Knights but also their leader of legend. He is a digimon of great power due to his possession of the "Alpha-Gain-Force". However, this very same factor has deemed him "Lord of the Empty Seat"; as he is destined to rule the Royal Knights but to be forever absent from their ranks. Thus his fate leaves to make only temporary appearances wherever his aid is needed.

Digital Monster X-Evolution


When attacked by Omnimon, DoruGreymon Digivolved to Alphamon, regaining his memories. He told that that he can't forgive Yggdrasil and thus Omnimon immediately sided with him and took him to see Yggdrasil. Before they could enter Yggdrasil's chamber they had to face DexDorugoramon, whom Alphamon managed to destroy with his Digitalize of Soul attack. They then entered Yggdrasil's inner sanctum to destroy the host computer but then Dexmon (the reformed DexDorugoramon) appeared and a violent battle began. Powering up to Ouryuuken Mode (though this was never mentioned in the movie), Alphamon attacked Dexmon - but his body also suffered all attacks he inflicted on Dexmon. This caused Alphamon to realize that Dexmon was his "other half", created from the data Yggdrasil removed from Dorugamon's body. Knowing this, he hurled his blade in a boomerang arc and grabed Dexmon as the blade returned, impaling them both. Alphamon transferred his X-Antibody to Omnimon before merging with Dexmon and regressing back to Dorumon.
