Monochromon

Monochromon is a Dinosaur Digimon. Monochromon is a Digimon with a rhinoceros-like horn growing from its snout. When that massive horn grows, it stands at half of its body length. The hard substance covers its horn and its top half is tough like diamond, and they say there is nothing it cannot pierce. Monochromon is said to excel at both offense and defense. Herbivorous and comparatively docile, once it is angered it will unleash a fearsome counterattack with its tank-like body.
