Phosphoros are blue common light element Slugs. When they reach 100 mph they turns into creature whose appearance is similar to that of an angler fish. The Phosphoros power type is light. In protoform, this Slug can illuminate itself. This abilitiy is shown being used before they sleep, revealing that the light the Phosphoro produces comes from inside its body, as seen by the glowing inside of its mouth, rather than originating on the surface of its skin.
A famous Phosphoro is Glimmer, who belongs to Eli Shane.
A ghouled Phosphoro is called a Photomo.
