This variant is, perhaps, the most nimble, if only for the fact that it is able to jump extreme distances with ease. Along with powerful hind legs, its body is streamlined and smooth to help it cut through air. Its namesake, however, comes from the radial plumes at its hindquarters. The main purpose of this rear crest seems to be communication, and is more pronounced in adult males. The Radiari also has tacky hairs on its feet which help it to climb and latch onto surfaces. It has the sharpest vision of the currently known Orr Kids.
