#4 The “Shalka Doctor”
In 2003, before the show was officially rebooted and Christopher Eccleston was cast as the Ninth Doctor, an unnumbered version of the Time Lord was introduced and given the nickname “Shalka Doctor” by fans. Fans had no idea what was going on!
Both the Master and the Doctor appeared in the series disguised as vampires and androids, respectively, both of which were concepts that the fan base as a whole did not appear to particularly enjoy. After only six episodes, the show was pulled from the air.
