10 Doctor Who Characters Who Came Back From The Dead

10. The Ninth Doctor (Father's Day)

Most of the Doctor's existence is spent rescuing his companions and dealing with their screw-ups, and Rose Tyler - though it was understandable why she did - made one hell of a screw-up in the Series 1 episode Father's Day.

Wanting her father - Pete Tyler - to live again, Rose saved his life after journeying into the past with the Doctor, creating a massive disturbance in an established timeline. This meddling resulted in a group of Reapers - winged creatures that are drawn to temporal paradoxes - showing up and killing a bunch of people at random.

And one of the people they killed was the Doctor, who gave his life to shield a group of survivors. A Reaper straight-up gobbled him whole, and he only came back to life when Pete bravely sacrificed himself, an act which re-established his death, fixed the timeline, sent the Reapers packing, and brought back everyone they had killed.

So if Pete hadn't made such a courageous decision? The Doctor may have stayed dead, which would've been bad news for pretty much the entire universe.
