When I finally make the figure, this is the bio I created for him awhile ago.
Created by the Sorceress of Castle Grayskull, R.A.D.A.R. is a recon android who's purpose is to detect alien races who may be an aid to or threaten Eternia. His first and main mission was to safely guide to Eternia an astronaut who is believed to be the future mother of the two heirs of the Sword of He. Years later, R.A.D.A.R. still watches the cosmos, and is now observing a planet called The StarBand. It is protected by the planets remaining law man, Rio-Blast, who may be contacted one day to help The Masters of the Universe.
