Gallantmon X is a Holy Knight Digimon and a carrier of the X-Antibody. Carrying out its devotion as a knight, this Gallantmon threw itself into the sacred battle and due to the X-Antibody, it was at last blessed with the supreme sacred armor, sacred lance, and sacred shield. It has sacred hybrid equipment combining "Red Digizoid", "Blue Digizoid", and "Gold Digizoid", which are rare metals, as well as Chrome Digizoid boasting the highest known purity. Since its form was remodeled in order to demonstrate its holy power, the lance of light emitted from its sacred lance Gram was amplified. In addition, it is said that Gallantmon's red mantle from before acquiring the X-Antibody was given to the hero, Leomon X.[3]


  • Lightning Joust (Royal Saber): Dispatches a strong blast of lightning from the Gram.
  • Shield of the Just (Final Elysion): Fires a beam which purifies everything from the Aegis.
  • Zeig Saber[4] (Sieg Saber): Elongates the lance of light emitted from the Gram.
