The Yurigans were a race of aliens that lived on the planet Zenitaf. They look similar to humans, but with skin that comes in various shades of bluish-gray, hair that usually has a slight blue tint. Their blue-gray tinting comes from the cobalt and other heavy metals in the soil of Zenitaf, which collects within their bodies, but does not harm them.
