Doctor Who: EVERY NuWho Villain And Monster Ranked Worst To Best

Appears in: Army of Ghosts/Doomsday, Daleks in Manhattan/Evolution of the Daleks, The Stolen Earth/Journey's End.

And then there was only one Dalek left in existence (that's got to be some sort of running gag).

Following the extermination of Daleks Sec, Jast, and Thay, Dalek Caan then took the spotlight - quite literally when Davros flicks a switch to reveal the totally deranged and jiggling Dalek in The Stolen Earth. You see, breaking a supposedly time locked Time War will play havoc with your mind and outer casing, but do wonders for saving your creator. Though try telling that to the pompous Supreme Dalek, who referred to Caan as the "abomination". That's gratitude for you! Never mind being the catalyst for bringing about the impending destruction of reality.

But with a knowing glint in his mad eye, Dalek Caan had the last, cackling laugh by ultimately masterminding the annihilation of the Daleks. Actually, you remember that running gag?
