Greymon

Greymon is a Dinosaur Digimon. Greymon's cranial skin has hardened so that it is covered in a rhinoceros beetle-like shell. It is an extremely aggressive Digimon, with a body like a lethal weapon covered in sharp claws and gigantic horns. However, it is highly intelligent, and if you're able to tame it then there probably isn't any monster as strong.[8]
