So for the Description, here's a start:
At first glance, a dragon warrior appears to be a human, orc or other sturdy humanoid completely coated in armor made of dragon scales; scale mail so exceptionally crafted it fits them like a second skin. A close inspection reveals the creature inside is no human fighter, but some sort of reptilian or draconic creature with finely scaled skin the same hue as their armor. Dragon warriors are armed with broad-bladed longswords crafted from the same material as their armor.
Organic Armory. An intimate inspection reveals a dragon warrior's scale mail is, quite literally, a second skin; a partially shed hide whose living scales have thickened into a suit of armor. Its longsword is similarly formed from the dragon warrior's body: a single massive scale, or perhaps an enormous fang, that has assumed the shape of a blade.
Children of the Dragon's Teeth. Legendary origins. Interfertility with humanoids? Alignment tendencies? Associated Magic Item (tooth of the dragon warrior? fang of wondrous power?).
Okay, back to the grindstone…

Draconic Scions. Dragon warriors come in ten varieties matching the five chromatic dragons (black, blue, green, red, white) and the five metallic dragons (brass, bronze, copper, gold, silver). A dragon warrior's scales match the corresponding dragon in color and texture and it often has minor features reminiscent of it, such as vestigial horns or crests. While metallic dragons are renowned for their benevolence and chromatic dragons are notoriously malign, dragon warriors rarely follow the true dragon's morality. While there may be a faint tendency towards their corresponding dragon's alignment (a red dragon warrior is slightly more likely to be evil or chaotic than a bronze one, for example), most dragon warriors are strictly neutral. The dragon warriors do have some other draconic traits though, such as being immune to the damage type of their dragon's breath weapon.
Children of the Dragon's Teeth. The common dragon warrior encountered by adventurers is an artificial being produced by a dragon tooth, an item that becomes a dragon warrior to serve the tooth's user; the transformed tooth is a temporary creatures that exist only briefly before crumbling into dust.
These dragon teeth imitate ancient myth, which says the first dragon warriors were born by planting the teeth of a slain legendary dragon in ploughed earth. Called Spartoi (literally "the Sown"), these warriors sprouted from these strange seeds armed for battle, growing to adulthood in moments. Some myths say the handful of Spartoi who survived their initial battlefield went on to found lineages of true dragon warriors. The legendary Spartoi and their dragon warrior descendants are living creatures, rumored to have incredibly long lifespans like a true dragon. True dragon warriors are fantastically rare creatures, and how they reproduce is unknown (or even if they can reproduce). The tales say dragon warriors, or at least the original Spartoi, would marry into human tribes, but the union of a Spartolos and Human normally resulted in humanoid offspring, not dragon warriors. A few modern sages claim dragon warriors can mate with dragons or reptilian humanoids as well as each other to produce newborn dragon warriors or eggs, but that is pure speculation.
I think that'll do, so it's just the
dragon tooth item to do.
