Captain Benegryph Goodvalor was a fictional character created by the Galactic Republic as part of a propaganda campaign in the Mandalorian Wars, based loosely off the exploits of Marn Hierogryph. Hierogryph's brother played Goodvalor in a series of recorded pro-Republic propaganda broadcasts during the war. Using a directional transmitter, Goodvalor flooded the Z-band of subspace radio, which the Mandalorians were using to conduct communication among their ground forces.
