Dragon/Arch Dragon

Arch Dragons (上位龍族) are Dragons that have more of the factor of the original Elemental Dragon than their Lesser and Medium Dragon brethren. They are the result of either a large amount of "Dragon Factor" being involved in the birth of a Dragon or a Medium Dragon evolving, depending on their individual circumstances.

Element Dragons
Element Dragons (属性竜) are Arch Dragons with elemental powers similar to their dragon lord brethren. Although these Element Dragons are not as strong as Dragon Lords, they're still quite formidable Special A rank monsters that require a platoon of Holy Knights to defeat.

After living for hundreds of years and gaining wisdom close to that of a human's, it is possible for an Element Dragon to evolve into a Dragon Lord.

Subspecies Dragons
Subspecies Dragons (亜種竜) are Arch Dragons that have failed to become Element Dragons. Though they might possess elemental abilities, they do not possess the attributes that make their Element Dragon cousins so deadly. Their strength is nothing to scoff at however, as they still rank on the lower end of Special-A. It is said that six Holy Knights are required to equal their might in battle.
