Dexmon

Dexmon is the final villain in the Digital Monster X-Evolution movie as well as the Digimon Chronicle and Digimon D-Cyber] comics. It is the result of taking away the life-data of Dorumon from DexDorugoramon. It is not officially a Digimon, as it lacks a Digi-Core.

Digital Monster X-Evolution
When DexDorugoramon was destroyed by Alphamon, the shattered fragments of his body recombined into the even more powerful Dexmon in order to defend Yggdrasil against Alphamon and Omnimon. Smashing through the floor into Yggdrasil’s inner sanctum, Dexmon managed to capture Omnimon and attacked him with an energy blast. However Alphamon flew in front of Omnimon, thus protecting him. He then called forth the Ultimate War Blade King Dragon Sword and used it to free Omnimon by slashing the sword in Dexmon's arm. However Alphamon's arm also took the same damage. Alphamon then fought the powerful evil Digimon and when he saw that every damage he inflicted up Dexmon was also thrown back to him he finally realized Dexmon's true nature. As a result, Alphamon threw his sword like a boomerang so that it impaled both him and Dexmon. He then told the shocked Omnimon that Dexmon was his shadow and afterwards gave him his X-Antibody while he and Dexmon merged back into Dorumon.

Digimon Chronicle
