Armadimon

Armadimon (アルマジモン)
A Mammal Digimon whose body is covered in a hard shell. It has a carefree, charming personality, but occasionally gets hurt if it gets carried away. Just like V-mon and the others, Armadimon is a descendant of an ancient species, so it is able to perform special Armor evolutions. Its Signature Move is striking the opponent with the elongated claws on its forelegs (Scratch Beat). Its Special Move is curling up its body and rushing the opponent (Rolling Stone).

Etymology
Armadi: Short for Armadillo, a mammal with armored plates.
