10 Doctor Who Episodes Where Everybody Dies
3. Warriors Of The Deep
1984's Warriors of Deep, a team-up between the Silurians and their Sea Devil cousins, quickly turns into one of Doctor Who's bloodiest massacres - and another in the Fifth Doctor era.
In this cold war-inspired serial, the TARDIS team arrives underwater in 2084 and immediately gets the blame for sabotage and conspiracy by the paranoid human crew. But whilst they're all bickering, and the Doctor almost drowns, the Silurians and Sea Devils plot to start an all-out war between an already feuding humanity. Their mission: reclaim the Earth, and wipe out everyone in their path.
Utilising their 'dreaded' sea creature known as 'The Myrka', the reptiles infiltrate the Sea Base and cut their way through the crew. With nothing stopping the onslaught, one crew member even tries to karate kick the sea creature, but instantly electrocutes herself instead. The Doctor finally manages to destroy the creature with an ultraviolent converter, but the battle's not over yet.
The remaining humans realise that the only way to defeat their reptilian foes is by flooding the Base with Hexachromite Gas. Which they do.
As the Silurians and Sea Devils die, they make sure to take the rest of the crew with them - either with lasers built into their 'third eyes', or sneak attacks from their nifty blaster guns.
'There should have been another way,' the Doctor mutters, surrounded by a roomful of bodies.
Death Toll: a whole Sea Base full of people, all of the Silurians, all of the Sea Devils. Everyone but the Doctor and friends, basically.
