Professor Y's costume contains elements of previous Doctor Who costumes - cravat (Tom Baker), pullover, hat and spats (Sylvester McCoy) and tartan trousers [Patrick Troughton).
As the title suggests, a parody of 1960's Doctor Who. Professor Y travels in space and time in a red phone box. His enemies include The Zybok's (war cry 'O-BLIT-ERATE') and The Mechanomen.
When Sister Boniface daydreams about being in the programme, she says 'My giddy Aunt!', the catchphrase of the second Doctor Who, Patrick Troughton.
Underpants are on sale at the convention. So literally, Professor Y Fronts.
Marc Silk (Zybok) was in a S11 episode of the audio series Doctor Who: The Fourth Doctor.
