Daemon/Devil Lord

Devil Lords (悪魔王), also known as Demons (魔神), are the final stage of evolution for Daemons. It occurs when a Daemon meets all 3 requirements of a Name, Material Body, and Divinity. They're beings of monstrous power and even have the potential to stand on even footing with True Dragons.

Appearance
Devil Lords, just like their predecessor Daemon Lord and Arch Daemon evolutions, possess an almost entirely Human appearance. The only non-human features they possess are the iconic claws, horns, and wings found on all members of the daemon race, although these can easily be hidden at their discretion. Their appearance, like that of all Spiritual Lifeforms, is dictated entirely by their self image. They might have been influenced by a body they previously inhabited or developed their own appearance naturally without the influence of other individuals.

Devil Lords all belong to a specific color lineage, with their color being apparent in their appearance. The color of a daemon's sclera will usually match their lineage and, although not always, other parts of their body match this color as well. Examples include, but are not limited to, hair color, iris color, and skin color. The color of their clothing usually also reflects the color of their lineage.

Trivia

 * All Primordials were born as Devil Lords. After being summoned into the Central World they lost most of their power. Guy Crimson was the only one to reclaim his strength as a Devil Lord by himself, with the rest needing to be artificially awakened by Rimuru Tempest.
