Romana II
The introduction of Romana's second incarnation in Destiny of the Daleks, a script credited to Terry Nation, but with several additions and alterations by script editor Douglas Adams, treats the concept of regeneration humorously. At the beginning of the serial, Romana changes bodily forms several times, rather like someone casually trying on different outfits, before deciding to take the form of Princess Astra, who had been played by Lalla Ward in the final serial of Season 16, The Armageddon Factor. This regeneration scene is controversial with some fans, as it does not conform with how regeneration is treated with regards to the Doctor or other Time Lord characters. Attempts at rationalizing Romana's regeneration have been made in licensed spin-off media, including the Short Trips short story "The Lying Old Witch in the Wardrobe" which speculates that the TARDIS was responsible for her regeneration. The canonicity of spin-off media in the Doctor Who franchise is unclear.
Romana II enjoys a more intimate relationship with the Doctor than her predecessor, to the point that some fans have assumed a romantic relationship with the Doctor. Although a relationship was never explicitly shown or intended by the writers, many fans have found the signs of a romantic relationship particularly evident in the story City of Death, perhaps reflecting the real-life romance between Tom Baker and Lalla Ward which blossomed during the production of that story, leading to their brief marriage. In many ways, she is the companion most like her Doctor - besides being of the same race and comparable intelligence, she occasionally mimics his sense of style, wields her own sonic screwdriver and can occasionally get the better of him in moments of banter and more practical situations. As her practical experience develops, she also becomes more assured and capable in the situations she encounters.
At the end of the serial Meglos, Romana receives word from the Time Lords recalling her to Gallifrey. The opening of the next serial Full Circle makes it clear that, having travelled with the Doctor, she no longer desires to return home. Before the issue can be resolved, the TARDIS falls through a Charged Vacuum Emboitment. Her final television appearance was in Warriors' Gate, where, along with the robot dog K-9, she leaves to forge her own path in the parallel universe of E-space when faced with a choice of remaining there or returning to Gallifrey. She also appears briefly in the 20th Anniversary special The Five Doctors through the reuse of footage from the uncompleted story Shada.
After the departure of both Romana I and II, both versions of the character also appeared very briefly in flashback sequences during the Fourth Doctor's regeneration in Logopolis as well as the Fifth Doctor's mind-copy in Resurrection of the Daleks. Romana would also be mentioned in Castrovalva during the Fifth Doctor's post-regenerative confusion, as well as in Arc of Infinity, in which the Fifth Doctor, in response to a reprimand from the High Council of Time Lords for "leaving behind", retorts that she "chose to remain in E-Space". Ward subsequently returned for a brief cameo as Romana in the 1993 charity special Dimensions in Time.
In "The End of the World" (2005), the Ninth Doctor stated that his homeworld had been destroyed and that he was the last of the Time Lords. Whether Romana was killed with the others has not been specifically established on screen. Of note, while various spin-off material (see below) reveals that Romana later became President of Gallifrey after returning from E-Space, this is clearly not the case at the end of the Time War; in The End of Time (2009–10), the Time Lord founder, Rassilon (Timothy Dalton), is shown alive again and claiming the title, though it is possible he did so after Romana's term.
