Osbert (Castle of Fear)
From Tardis Wiki, the free Doctor Who reference
Osbert appeared in 1899 as a memetic conflict.[statement unclear] This led to the Fifth Doctor and Nyssa.[statement unclear] In 1199, he saw the demons and helped Nyssa from a boar trap. He was in fact a Rutan who had duplicated the original Osbert. (AUDIO: Castle of Fear)
