Horse Dragons have equine-shaped bodies and hooves instead of claws, which allow them to be fast runners. They specialize in running takeoffs, which are quicker than taking off from a stand-still. Horse dragons are able to stalk their prey from the ground then quickly execute an aerial attack for the kill.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Pegasumon is a Horse dragon, and if there was any such thing as a ninja dragon, he would fit the description. Extremely fast, both on his feet and in his reactions, this dragon literally zips around all over the place. Quite often, people don't even realize that he has been and gone, as all they feel is a gust of wind. Pegasumon is just as swift on his wings, and shoots through the air so fast that other flying dragons are left behind feeling slightly dizzy. He enjoys swooping down on people below him, picking them up and taking them for a short ride- whether they want to or not. He always gently puts them back down again, and fans his wings to help them recover consciousness. He has also taken to carrying around anti-nausea pills after certain incidents while carrying timid dragons who had just eaten.
