Magnamon X is a Holy Knight Digimon and a carrier of the X Antibody. One of the "Royal Knights", it digivolved through the power of the Digi-Egg of Miracles. Its armor is made of the super-metal Chrome Digizoid, but it has been completely integrated with Magnamon's body through X-Digivolution, to the point that it possesses a nature similar to muscles. During battle it will increase in hardness, and if it enters the "Gold Digizoid" state in which its entire body shines gold, it is completely invulnerable.
- Plasma Shoot: Fires a shot of ball-shaped plasma.
- Extreme Jihad: Emits the utmost power of the Digi-Egg of Miracles in the form of an energy wave from its entire body.
Magnamon X is an enhanced version of Magnamon and retains much of the same shape only with enhanced armor. The armor itself is sharper and more elaborate than the base form, with the addition of As'ma Green at the helmet, shoulders, hands, knees, and loin-guard. Its loin-guard no longer features the emblem on the Digi-Egg of Miracles.
- Magnamon X-Antibody (マグナモンX抗体)
Standard naming scheme for Digimon who are not natural carriers of the X-Antibody.
