Digital Monster X-Evolution
DexDorugoramon was created by Yggdrasil with a part of the Data of the captured Dorumon. The newborn Digimon then started to create a huge number of Digi-Tama (Digi-eggs), from which DexDoruGreymon hatched, which then started to delete the Digital World. Later DexDorugoramon confronted Alphamon and Omnimon in a large room to stop them from entering Yggdrasil's lair. It immediately attacked and when Omnimon attacked it with his Supreme Cannon, the damage caused by the blast was immediately healed. The evil Digimon then used it's tail to slam Omnimon in the wall and it then wanted to attack Alphamon. Alphamon however used his Digitalize of Soul attack on the evil Digimon, thus shooting it into pieces. Afterwards the two Royal Knights entered Yggdrasil's lair but while they confronted the Host Computer, the pieces of DexDorugoramon reformed into Dexmon, which then again attacked the two knights.
