Valerons were the winged humanoid inhabitants of Valerus, a world in a sub-atomic universe. A warrior race, they destroyed the surface of Antar, killing most of the Antarians. They refused to believe their scientists' warnings that the arrival of a blue star in their solar system was a threat to them. When the Third Doctor and Liz Shaw arrived, the Valerons captured them, believing them to be Antarian spies. They escaped with the help of the Valerons' prisoner, Dynil. The Valerons were presumably wiped out by the radiation from the blue star some time afterwards. (PROSE: A Universe Called Fred)
