Forever War: Ddraig and Albion have basically forgotten what the fight was originally about.Back from the Dead: Issei's consumption of Amrita allows Ddraig to temporarily manifest after 8 minutes have passed in his Diabolos Dragon form.Heavenly DragonsDragons based from the Arthurian legend of Merlin watching an endless colossal fight between a red and white dragon (who symbolises Wales and England, respectively). Azazel commented that most people know better than to piss one off. Unstoppable Rage: With enough provocation, a Dragon will enter "Outrage" mode, becoming significantly more powerful and vicious.Super Toughness: Their scales can be very hard to damage without a Dragon Slayer.Too Powerful to Live: Many Dragons, particularly the Evil ones, were killed off or sealed to stop their rampages.Our Dragons Are Different: They can be Western with four limbs and a pair of wings, or Eastern with a serpentine body.Kryptonite Factor: The only things that can kill dragons are dragon-slaying weapons like Issei's Ascalon or the blood and attacks of the fallen angel Samael.

Fafnir requires his contractor to give him something for his help (which, in Asia's case, is often lingerie), and Tiamat's briefly mentioned hatred of Ddraig is later revealed to be the result of Ddraig losing some treasure that he borrowed from her to fight Albion.

Breath Weapon: As expected, many can breath fire.
