Digital Monster X-Evolution
The mysterious little Digimon known as Dorumon, characterised by the strange stone in his forehead, is, in actuality, not a natural Digimon but an artificial being created by Yggdrasil, the sentient computer that controls the Digital World, with the intention of using him to bring about the second phase of its Project Ark scheme.

Released into the Digital World, Dorumon was ostracised for possessing the X-Antibody and came under threat from other Digimon, including a Leomon, who sought to claim the X-Antibody for his own. Fleeing from the Leomon through a forest, Dorumon seemed doomed until Leomon relented, knowing that, even with the X-Antibody, he would live no longer. Asking Dorumon to live for him in the new Digital World, he died.

Bullied by a group of Mushroomon and forced to flee into a river, Dorumon came to rest in an old temple in a barren region of the plain, where he soon came into contact with WarGreymon X, who was in the middle of a battle with the Royal Knight, Omnimon and requested that Dorumon look after Tokomon until he returned. Dorumon agreed, happy to have a friend but soon, the duo witnessed another attack by Omnimon on a herd of innocent Digimon and, although they both bravely attempted to fight back against the Royal Knight, almost became victims themselves until WarGreymon X and MetalGarurumon X arrived to save them. In the course of the ensuing battle, however, Tokomon was fatally injured and MetalGarurumon X used his X-Antibody to resurrect him as Tokomon X. Weakened by this, MetalGarurumon X collapsed and Dorumon, believing he was dead, was overcome with emotion and memories of Leomon and Digivolved to his Champion form of Dorugamon.

Subsequently, Dorugamon was captured by Magnamon and had his data split by Yggdrasil, creating DexDorugoramon, who yielded Digi-Eggs that hatched into a swarm of DexDoruGreymon, which Yggdrasil would use to raze the Digital World. Dorugamon Digivolved to Dorugremon to battle them and was then granted access to Yggdrasil’s realm by Gallantmon X to learn the secrets of his creation. There, in battle with Omnimon, he assumed his Mega form, revealing at last his true form and destiny – he was Alphamon, legendary leader of the Royal Knights. Together, Alphamon and Omnimon destroyed DexDorugoramon, who then revived as Dexmon and resumed the battle with them in Yggdrasil’s inner sanctum. Realising his connection to Dexmon, Alphamon sacrificed himself by impaling them both on his blade, passing his X-Antibody to Omnimon before recombining with Dexmon and forming Dorumon again. Omnimon subsequently destroyed Yggdrasil, re-birthing the Digital World as it had been and allowing Dorumon and Tokomon to be reunited.

''It is unclear what Dorumon’s specific connection to the legend of Alphamon is. There are two possible explanations – either Alphamon truly existed at a time in the past and Yggdrasil used his data in the creation of Dorumon or Dorumon was fulfilling the legend by becoming Alphamon for the first time.''
