Doctor Who: EVERY NuWho Villain And Monster Ranked Worst To Best
42. Torajii
Appears in: 42.
Friendly word of warning to those about to embark on an illegal fusion scoop tour: don't go near any living suns. Which is what the crew of the SS Pentallian did when mining one called Torajii. This positively infuriated the sentient star, so it possessed certain members of the crew, who in turn smashed up the ship's engines and incinerated others.
It's captivating seeing the Doctor tested to the extreme here: seeing him fierce and frightening one moment in telling Martha that he could kill her and everyone else, then genuinely scared and screaming the next when being agonisingly frozen to temporarily stop the creature within.
