Rhinomon X is a Mammal Digimon and carrier of the X Antibody. Its armor has been polished even further, not only raising its defense but also, more importantly, completely changing its attack pattern to become more aggressive. Most prominently, its horn has been transformed into a sword, which it uses for various attacks. Its personality has also changed to become more hostile, and it will boldly challenge any Digimon it deems powerful to a duel.
