Barbarella

The Ninth Doctor jokingly called Rose Tyler "Barbarella" when she was going to go out in 1869 wearing her early 21st century attire, he said she would "start a riot". (DW: The Unquiet Dead)

Following her death from eating a Kaled mutant, Iris Wildthyme, a renegade Time Lord, regenerated into a Barbarella-like incarnation. She encountered the Eighth Doctor in this form in the Obverse. (EDA: The Blue Angel)
