The entity that generally goes by the name "Jack Runner" is not really a man. Oh, he takes the form of a man often enough, a handsome one at that, but that's just a form, one of many. He is really a dark-scaled Great Horned Dragon. Well, a dragon hatchling but even so, the spines attest to the type of dragon he is. When he is in his human form, he wears the armor and garb of a Mystic Knight.
