Greymon

Greymon
Greymon is a dinosaur digimon, more closely modeled after the classic, flat-footed, upright depiction of a theropod dinosaur. It has a well muscled chest and forearms, orange skin with blue stripes, and a brown helmet with antler like horns on the side and a single horn on the nose - making it resemble some sort of fusion between a Allosaurus and Ceratosaurus. It is approximately 15 to 20 feet tall.The name "Greymon" comes from a misspelling of the English word "great".
