Guilmon X is a Demon Dragon Digimon and carrier of the X Antibody. Due to the X-Antibody, the engraved "Digital Hazard" mark has vanished. That is because it accepted and contained its power within its body. It still hasn't awakened to that power, but if it grows up the right way, it can be said that its qualities for maturing into a true guardian of the Digital World will have improved. Since its instincts as a Virus-species have also increased, its personality has become more aggressive.[2]


  • Fire Ball (Fireball) : Spews out a powerful flame shot.
  • Fire Mitt: Punches the opponent using fists wrapped in fireballs.
  • Rock Breaker: Destroys rocks with its sturdy foreclaws.


Guilmon X is an enhanced version of Guilmon. It lacks Guilmon's Digital Hazard and some of its triangle markings.
