Dinorexmon is a Dinosaur Digimon and carrier of the X-Antibody. With strength far in excess of other Dinosaur Digimon, it is a carnivorous Digimon named the "King of Terror" due to the unparalleled ferocious nature it displays in battle. With its talons, which are almost half as long as its body, it seizes the opponent, snaps and brandishes its gigantic jaws at them, then kills them. Its exceedingly brutal manner, which appears in the finest battles of a world where the weak are food for the strong, is probably the reason it is called "King". Also, partly due to it fighting with other Dinorexmon, it is said that the population is very small.
- Splatter Hunting: Seizes and kills the opponent with its talons.
- Ogre Flame: Fires extremely high-temperature grenades from its mouth, which have a semi-fluid form similar to magma and burn down their surroundings even if they don't hit the opponent.
Dinorexmon is a large, tailed dinosaur covered in hard, green scales. It stands on two legs but possesses extremely large hands with sharp claws. The second digit on each of its feet features a sickle-shaped claw similar to the Deinonychus, but with exaggerated length.
