Greymon

Greymon (Greymonstrum saurus) is species of non-avian tyrannosaurid that that originally did not exist, but has since been created by SciiFii due to demand from Digimon fans who wanted real life Digimon-like animals as pets. It is a rather small tyrannosaurid unlike its more distant relatives such as Tyrannosaurus, growing to be around 9 feet long and weigh around 150 pounds. Its head is covered in hardened skin, which resembles the shell of a rhinoceros beetle. It is an aggressive reptile towards other predators, with a body covered in sharp bony armor, large horns, and a thick lion-like feathery mane (though only males have them, similarly to how only male lions have manes), it is well protected from predators as large as a grizzly bear. However, it is highly intelligent and is easily tameable, since it has been genetically engineered to be friendly around humans and domesticated non-human animals.
