Ankylomon

Ankylomon is a Dinosaur Digimon whose name and design are derived from the Ankylosaurus. Not only is its whole body covered in hardened skin, but it also has hard osteoderms coming out all over. Therefore, its charge attack has extraordinary destructive power. As a fundamental result of being a herbivorous Digimon, it is not ferocious, but it is decidedly not timid, and is the possessor of a brave character.
