Doctor Who Series 9: Who Are The Hybrids And What Does It All Mean?
5. The Doctor Donna
There has been a lot of speculation as of late that David Tennant and Catherine Tate may be making an encore performance on Doctor with a recent appearance in Cardiff where the show is filmed. Fans assumed a return of the Tenth Doctor and Donna might link to the reason the Twelfth Doctor has Caecilius' face but that was dealt with rather quickly in The Girl Who Lives with a simple flashback to The Fires Of Pompeii.
Both Tennant and Tate are coming back to Doctor Who for a series of Big Finish audios but now might be the perfect time to have them back on the show too. The end of series four saw the creation of the Human - Time Lord hybrid, the Doctor-Donna, with the human metacrisis Doctor and Donna infused with Time Lord DNA working to defeat Davros and the Dalek crucible.
Will these hybrids make an appearance of sorts in series nine? It could make for a surprising and thrilling series finale.
