Doctor Who: 20 Things You Didn’t Know About The Waters Of Mars
6. The Ice Warriors’ Absence
Upon watching The Waters of Mars, fans of classic Who might have wondered "Where are the Ice Warriors?"
These chilling foes from way back in the day were also inhabitants of the red planet. They get a namedrop during the episode, but why did they not have more to do on their homeworld?
As it turns out, this question was answered in a deleted scene (11:00 in the video below).
While pondering The Flood, the Doctor theorises that, although the Ice Warriors were able to imprison it inside a glacier, they were not fully able to defeat it.
This led to them fleeing Mars, leaving their menacing enemy behind for some other unfortunate souls to come across.
