and starred in the 2021 New Year's Day special, "Revolution of the Daleks". "Fugitive of the Judoon" also introduced a new, previously unknown, incarnation of the Doctor referred to as the Fugitive Doctor portrayed by Jo Martin, a role that carried over into the thirteenth series and subsequent specials. Walsh and Cole left the series following "Revolution of the Daleks", and were succeeded by John Bishop for the thirteenth series. Whittaker, Gill, and Bishop continued their roles through the 2022 specials; Whittaker then departed alongside Gill, and Bishop. The final special, "The Power of the Doctor", commemorating the BBC's centenary, saw the return of David Bradley, Peter Davison, Colin Baker, Sylvester McCoy, and Paul McGann as the First, Fifth, Sixth, Seventh, and Eighth doctors, respectfully. Sophie Aldred and Janet Fielding also starred in the episode, reprising their roles as Ace and Tegan Jovanka. Walsh briefly returned in the episode as well, with William Russell, Katy Manning, and Bonnie Langford portraying former companions Ian Chesterton, Jo Grant, and Mel Bush. Chesterson potentially broke a Guinness World Record for "longest gap between TV appearances as the same character" with over 57 years since his last appearance in 1965. On 8 May 2022, Ncuti Gatwa was cast as the Fourteenth Doctor. David Tennant and Catherine Tate were also announced to be returning to the series in a similar set of specials airing in 2023 to commemorate the 60th anniversary of the series. Following Tennant's re-introduction to the series at the end of "The Power of the Doctor" it was revealed that Gatwa would actually be playing the Fifteenth Doctor while Tennant would hold the role of the Fourteenth. Bernard Cribbins is also set to appear in the 2023 specials as Wilfred Mott in a posthumous role because of Cribbins death after completing filming. Gatwa will then assume the role from Tennant; Gatwa's first full episode will premiere "over the festive period in 2023", and the fourteenth series will be screened in 2024.
