Jesmon GX is a Holy Knight Digimon and carrier of the X-Antibody. It is the final form of Jesmon that awakened its true power by enduring strict training from Gankoomon and fully mastering it. Its appearance, overflowing with fighting spirit and a sense of justice throughout its body, is covered in the red color of burning flames. The "Unlimitive Gauntlet", which has become its main weapon, is a piece of equipment used for both offense and defense that switches between Sword, Knuckle, and Shield Modes depending on the situation. By digivolving further, the Tactical Arms has turned into a wing-shaped energy construct, and its flight capability has also increased drastically.
- Seiken Meppa (聖拳滅破? lit. "Sacred Fist Destroyer"): In its Arms form, it unleashes a subluminal combo-attack that succeeds Gankoomon's secret technique.
- Knights' Intruder: Jesmon GX itself turns into the "Knights' Intruder" spiritual vessel, the fourteenth Ultimate-Battle-Blade that should not exist, by concentrating the energy of the Royal Knights, and becomes an assault sword of judgment that instantly erases the opponent no matter how strong they are.
