A small skeletal rat wearing a tiny black robe and carrying a tiny scythe. When Death briefly ceased to exist during Reaper Man, the Death of Rats was created to handle the business of rat mortality. He survived Death's return and is now a semi-independent entity who mostly accompanies Susan when she is handling Death's affairs. He communicates in "SQUEAK." He rides a raven called Quoth who insists he does not want a cracker, is not going to say that, and keeps saying it anyway.
