WarGreymon X is a Dragon Digimon and a carrier of the X-Antibody. Because of its mission as a true hero, it must have 100% success in battle. It has imparted the strongest toughness of the "Brave Shield" to the "Dramon Killers", leading to it possessing perfected equipment of unified offense and defense. Due to its fighting style, in which it instantly plunges into the heart of the enemy with the vernier it has equipped to its back, which boast explosive acceleration at the expense of it being able to fly for extended periods, it has certainly become the strongest form of land combat Digimon, a "Land War Hero".
