Greymon X is a Dinosaur Digimon and carrier of the X-Antibody. The most outstanding among Dinosaur Digimon as a Combat Species, Greymon became even more aggressive. Although it has a relatively small build among Dinosaur-types, many of which are large Digimon, it has fully exhibited its carnivorous dinosaur-like ferocity, winning in battles and increasing its own strength. By enhancing "Nova Blast" to its utmost limit in its mouth, it acquired its "Mega Burst", which possesses explosive power.[2]

  • Mega Burst: Uses a technique possessing explosive power in which it enhances its "Mega Flame" within its mouth to its utmost limit.
