File under "Rumour" for now, as a UK tabloid is reporting that Doctor Who's most famous monsters might be getting their own spin-off series. This has come from the Mirror, and a reporter who is generally more often right than wrong. It is all part of the Disney+ streaming deal. Something which might lend credence is the fact that Russell T Davies has spoken before about creating a "Doctor Who Universe" akin to the Marvel and Star Wars franchises. Aliens mentioned include Daleks, Cybermen, Sontarans and Weeping Angels. These episodes would not feature the Doctor at all, but would be designed to show what these creatures get up to when the TARDIS isn't around.
If this does prove to be more than rumour, it might also open the door for past Doctors to get an outing. There has always been a demand to see more of Paul McGann's incarnation, for instance. Some old companions might also get another outing.
Not sure if there would necessarily be room on BBC 1 for too many spin-offs, so if this does come off then some of it at least might be exclusive to Disney+.
