* CompleteMonster - Erra fits this bill. She doesn't deny it when Kate calls her a psychopath [[FishOutOfWater (although she has to look up what the word means)]]. When her children annoy her [[OffingTheOffspring she kills them]] and [[PeoplePuppets pilots their undead bodies]]. [[DisproportionateRetribution She once "threw a hissyfit and blew up Bablyon"]], [[ForTheEvulz enjoys scaring crowds, just cause]], [[spoiler: and she tells Kate that because she and Roland are immortal, one human death doesn't mean anything to them so Kate shouldn't whine about [[YouKilledMyFather Roland killing her mother]]. Ouch.]]
* MagnificentBitch - Aunt B, ''especially'' in the fourth book.
* NauseaFuel - The description of dead shapeshifter Joshua's body in the fourth book. He is covered in hard red bumps except for the places where he has open sores, and then ''his nose comes off''. Euurgh.
