10 Doctor Who Villains Who Actually Won
2. Madame Kovarian (A Good Man Goes To War)
Not just called "Eyepatch Lady" as some people thought, Madame Kovarian enjoys an unprecedented victory when she actually manages to fool the Doctor - which doesn't happen very often at all.
In a plot involving a kidnapped Amy Pond, some Headless Monks, and good old Danny Boy from Victory of the Daleks, it momentarily looks like #TeamDoctor has come out on top. There's a fierce battle which sees brave Strax get killed and stupid Dorium Maldovar get his stupid head cut off, but other than that, everything seems fine and dandy.
But unfortunately, Eyepatch Lady has the last laugh when she reveals that the child they have in their possession - the child that was the entire point of this mission - is a fake.
The child in question is of course Melody Pond, aka River Song. River is subsequently taken by Kovarian and the Silence, who raise her to kill the Doctor before he can reach Trenzalore.
So not only did Kovarian embarrass the Doctor, but she also gave the show one of its best recurring characters. That's a double win!
