Romana III

The third incarnation of Romanadvoratrelundar (commonly known as "Romana"), was more ruthless than her first and second incarnations.

Biography
Romana had by this time became War Queen and President of the Nine Gallifreys. She regenerated knowing that she would need a harder personality for the upcoming War with The Enemy. As a result she became less friendly towards the Doctor. Physically, she resembled a beautiful dark-haired woman. (EDA: The Shadows of Avalon)

After the end of the War with the Enemy and the destruction of Gallifrey (EDA: The Ancestor Cell) (a separate event from the Last Great Time War), Romana's fate was unknown.

Behind the scenes

 * Writers involved in the War arc book of Eighth Doctor Adventures novels based Romana III's described appearance on that of the American silent film actress Louise Brooks, although upon meeting this incarnation for the first time the Eighth Doctor noted that she now looked worryingly like his mother.
 * In IDW: The Forgotten, the Tenth Doctor says Romana "did quite well for herself ... until the Time War". The comic gives no clue as to whether the Doctor is referring to Romana III or the second incarnation or even to an incarnation after Romana III.
