Draconian Prince

A Draconian Prince was the son of the Draconian Emperor who ruled at the time of disrupted peace between the Earth and Draconian empires in 2540.

He was initially distrusting of the Humans, and believed the Third Doctor and Jo Grant to be enemy agents working on their behalf. When he learned the truth of the Master and the Daleks' involvement, he assisted them in stopping their plans. (TV: Frontier in Space)
