Drakengard Dragon design guide

This is just an extremely basic design guide. text form only, to establish some rules for Drakengard dragon designs for myself and a few friends to follow. These are mostly an attempt to remain as close to design rules and philosophy as possible so they remain accurate to Drakengard, factoring in 1, 2, 3, 1.3, and other supplemental material such as Nier: Reincarnation.

- All dragons have a slightly varied head shape, with up to three pairs of horns (six horns) usually symmetrical, unless the horns may overlap in any way.

- All dragons have up to four colors, not including eye and flesh color. These colors are the main body color, underside color, horns, horn fade (not all dragons have a horn gradient) and feet/wings color.

- Any "marking" covering the wings does not extend onto the wing arm or membrane, and only covers the index and thumb finger on the wing's hand, and any marking on the feet does not extend past the ankle. Anything other than this is likely paint to tell the dragon apart from others in the chance that it may be dealing with humans.

- Only black and chaos dragons may have red eyes, and if so they are always #FF0000 flat red with no hue variation.

- All dragons have no visible sclera, and their pupils are always slit. Dragon eyes are generally one solid color.

- Dragon anatomy is unusual, consisting of a chest that is humanlike in proportion, an enlarged pubis bone, proportionally sized arms (for a human, not a dragon) and powerful hind legs.

- Two dragons will never have the same exact horn shape, even if related or direct reincarnations.

- Dragons have "stages" and otherwise do not physically change as they age past a certain point. Their main body color may shift ~30 points in hue in either direction but must visually be within the same color range. A red dragon's main body color will always be red, even if their underside color may change more drastically from, for example, a light tan to a dark beige.

- White dragons do not have a main body color that follows the above rule, instead their underside color may transition from the underside color of their former pre-reincarnation self to something else entirely. In both cases, this is a transitory process and the colors will not be random.

- Dragon feet/hind claws either may mimic avians, dinosaurs, or in the case of chaos and black dragons they may be structured identically to human hands.

- Black dragons are either monochrome or tinted blue.

- Chaos dragons may have bone-like faces, protrusions resembling exposed bones or an exposed spine, markings, and more than the usual three to four maximum.

- Chaos dragons will never have any eye color other than red, and their eyes lack discernible pupils. Instead, their eyes just glow red.

- Flesh and inner mouth color may be any solid color.
