Been meaning to make this removal for a while but haven’t been able to get around to it.
Who Is She?[]
Madame Kovarian is a high ranking member of Papal Mainframe (a religious organization in outer space). She serves as the main antagonist of the entirety of the Eleventh Doctor’s storyline. After learning that the utterance of the Doctor’s name through a crack in time will bring the Time Lords out of a pocket universe that they were locked in during the Time War and risk the continuation of the war, Kovarian travels back in time with the Silence (a race that was genetically engineered by Papal Mainframe to be forgotten at the moment they are no longer being looked at) and comes up with numerous ways to kill the Doctor, from blowing up his Tardis (which is ironically what caused the cracks in time in the first place) to kidnapping Melody Pond (also known as River Song) and then raising her as a weapon to eliminate the Doctor.
Why Doesn’t She Qualify[]
While kidnapping Amy and her daughter, and brainwashing River into killing the Doctor slightly stood out due to the personal nature of these crimes, her actions severely pail in comparison with all the other villains in the show. Things like mass murder and reality destruction are virtually the norms of the series, and her only action that serves as any valid competition to the heinous standards is the destruction of the Doctor’s Tardis as this nearly unraveled the entirety of space and time, but all implications show that this was unintentional and against her actual plan. Her only goal was to get rid of the Doctor.
And despite her psychotic and sadistic nature, she can arguably be seen as a well-intentioned extremist, because the very reason she is so hellbent on killing the Doctor in the first place is so she can prevent the Time Lords from continuing the Time War and raining hell on the universe.
Conclusion[]
I will admit that I’m not 100% sure because her actions do, in a way, stand out through being particularly personal, and she was in one way or another behind almost every single storylines during the Eleventh Doctor’s era (the cracks in time, Trenzalore, the Impossible Girl, River Song, the Silence, the Pandorica, the death of the Doctor in Utah, etc.), but all you have to do is compare her to the other villains, and she is a cut.
