Biology
In his Lightside form, Azure Dragon takes on a humanoid appearance, reminiscent of the humanoid form of Nandaryuuou. He has long, dark blue hair, and two cream-colored, short antlers.

His body appears to be clad in a skin tight black suit, or perhaps countless black scales, over which he wears light blue and green clothing, as well as a multi-layered belt.

In his Shadowside form, he has the appearance of a dragon, similar to how he appears in the present series.

His hair is now a dark blue mane, and his antlers have grown bigger. His scales are light turquoise, and his underside is light blue.

He has four limbs, and a crest of the same color as his horns on his chest.
