Doctor Who: EVERY NuWho Villain And Monster Ranked Worst To Best
111. Yvonne Hartman
Appears in: Army of Ghosts/Doomsday.
The big boss of Torchwood wasn't a villain per se - she just happened to be the face of the secretive institute that the Doctor despised, who set in motion the epic events that led to the Battle of Canary Wharf. And Rose ending up in a parallel universe.
Still, you wouldn't wish the horrific Cyber-upgrading process on anyone, and Miss Hartman did make a notable effort to remember her employees' names. Plus, fair play to her for continuing to defend Queen and Country even after being fully converted.
