Monochromon

Monochromon
Monochromon is an Ankylosaurian Digimon that resembles a monoclonius. His horn is his pride. This horned dinosaur gores his enemies with the rushing power of his charge. When his horn grows, it reaches the size of the extent which is close to half of his length. His horn and the substance which covers his body are hard like diamond and cannot be pentrated. It is placid and herbivorous, but if it is upset, it draws out the power of his fearful strike.
