Doctor Who: EVERY NuWho Villain And Monster Ranked Worst To Best
61. Sisters Of Plenitude
Appear in: New Earth.
Cats plus nursing nuns is such a winning combination, especially five billion years into the future where the Sisters of Plentitude - which included Novice Hame - are miraculously curing all known diseases - all too miraculously.
There's a Coma (1978), Extreme Measures, and The Matrix about it all as the Doctor and Rose (really Cassandra in disguise) discover the aforementioned Flesh/Plague Carriers and what they're horrifyingly used for. The top cat Matron Casp is as merciless as a moggy with a mouse when she orders one Flesh to be incinerated because it cried out for help.
They're not the worst cats, to be honest - just check out those freakish felines from a certain 2019 film of the same name.
