MedievalDukemon is a Warrior Digimon and a carrier of the X Antibody. In "Witchelny", it is praised as the "Legendary Hero", as it suddenly appeared and drove out the foreign invaders in ancient times, and although it's not certain, it is said that it transcends time and is still in existence.

MedievalDukemon is the first form of Duke, one of the Holy Knights who can restore Dragon Spirits. MameTyramon is his servant. When asked, he refuses to give the Dragon Spirit to save Grademon and instead challenges them to battle. Though seemingly defeated, he proceeds to kill Grademon and then implant the Dragon Spirit, revealing that to restore the Dragon Spirit, the Digimon needed to be near-death. When he senses trouble, he digivolves to Gallantmon X and sends the group on their way.
