Mx was a gender-neutral honourific used on Earth. This was Orr's preferred title, as they had no fixed gender. (AUDIO: Superiority Complex)
Mx Neon was the curator of a trans-temporal museum, containing the Relic Room. They hired Professor River Song to recover a painting. (AUDIO: The Web of Time)
Calypso Jonze preferred not to use any honourifics, only to be referred to by either their first or last name. The Sixth Doctor called them Calypso, while Mrs Constance Clarke settled on Jonze, as the closest option to her usual etiquette. (AUDIO: The Lovecraft Invasion)
Behind the scenes[]
- In the real world, Mx gained widespread recognition across the United Kingdom in the mid-2010s as a gender-neutral title on passports, driving licences, and in major institutions like banks, broadcasters and the Royal Mail.[source needed]
- It is generally pronounced mix, as in the DWU, or otherwise mux; occasionally mixter.[source needed]
- Coincidentally, "Mx" was an alias used by Mickey Smith in the 2005 short story Alien landing confirmed, predating the title's growth in the 2010s.
