Former Time Lord Christopher Eccleston says it's time the sci-fi hero had more female enemies.
Jodie Whittaker became the first female Doctor in 2017 and Christopher, who was the ninth Time Lord, has said it's time for the baddies to be women too.
The show sees evil cyborgs turn humans into more Cybermen and the 57-year-old actor has called on producers to pencil in cyberwomen as well.
There has never been a cyberwoman in the series, but one did appear in the spin-off Torchwood in 2006.
The actor who played the Doctor for a single series in 2005 also challenged the producers to look at history from a female perspective and revealed he'd like Jodie to meet Suffragette Emmeline Pankhurst in the next series.
He told Doctor Who magazine: "It’s great that we have a female Doctor... we should take that further in the way we look at history. Look at it through a female lens."
He added: "The Doctor with a Cyberwoman – that dynamic, feminine element of himself... his flirtatious nature... would be great with a Cyberwoman."
Jodie's role as Doctor Who is set to end after it was reported in January that producers are planning for the Time Lord's fourteenth regeneration when it returns later in the year.
An insider said at the time: "It’s all very hush-hush but it is known on set that Jodie is leaving and they are gearing up for a regeneration.
"Her departure is top secret but at some point over the coming months the arrival of the 14th Doctor will need to be filmed. It’s very exciting."
Christopher went on to discuss why he felt he had to keep his accent during his spell as the Doctor.
"One of the reasons why I didn’t like the show when I was a kid was I couldn’t put myself in that role," he said.
"I know Tom Baker is a Scouser but he certainly didn’t sound like one to me.
"The series seemed to be saying that if you’re white and you’re middle class, you have ownership of intellect and science."
