10 Doctor Who Characters Who Can Never Die

10. The Family Of Blood

Immortality sounds like a blast on paper, but in practice... potentially not. The Family of Blood learned that the hard way in Series 3, with the Tenth Doctor trapping each of the four members in some increasingly dark, everlasting situations.

The Father was wrapped in unbreakable chains and imprisoned; the Mother was tricked into the event horizon of a collapsing galaxy; the Daughter was trapped in every mirror in existence; and the Son was suspended in time while dressed as a scarecrow, left to watch over the fields of England.

It's chilling stuff, but on the plus side, the Family's primary goal was to become immortal. So, technically, the Doctor granted their wish. It's not his fault that they didn't specify exactly what they wanted their eternal fates to look like!

While the Daughter was freed by the Thirteenth Doctor in a lockdown webcast written by Paul Cornell (the writer of the original episode), the canonicity of that story is up for debate. In terms of the actual show, each member of the Family is presumably still trapped in their grisly scenario - so it's possible that the Doctor could revisit them one day. And who wouldn't want to see that rematch?
