Doctor Who/Recap/S4/E07 The Macra Terror

< Doctor Who‎ | Recap‎ | S4


The TARDIS arrives at a human colony that seems happy enough but, as it turns out, the colonists are being mind-controlled by a race of giant crabs called the Macra. The Macra are using the humans to mine the toxic gases they need to survive.

This is an emergency! Control must be believed and obeyed! No-one in the colony believes in Macra! There is no such thing as Macra! Macra do not exist! There are no Macra!
Control protests too much.

Ben is affected by the Macra mind-control and starts to turn against the others, but the Doctor succeeds in breaking their hold and Ben destroys the gas-mining equipment, killing the Macra and freeing the colonists.

The Macra had a slightly surprising cameo four decades later in the Tenth Doctor episode "Gridlock".

Tropes

 

Ben: They got that bloke all over the place like a blinking politician.
Pete: He is our controller. We are always pleased to see him. He brings us encouragement.
Ben: Oh, he's not a politician then!
