Primus
It is a parasitic mimicry lifeform creature with no fixed gender. When it meets Fishcake, it's mimicking the appearance of a human male. Because a parasitized body will be digested so it often needs to replace its lower body. Nobody knows how the race of PR came into existence. They could possibly be born from someone's wishes, or perhaps they are another entity whose hopes were distorted by The Outer Ones. But currently, there are no answers to all of this. Out of curiosity, it agrees to join Fishcake's journey, together exploring the secrets about itself and the world.
It likes to keep brightly colored fish as pets in its mimetic fluid (which is also a digestive fluid). Although these fish are dissolved within a few days, it will go and catch new ones and pretend they are still the same fish as before.
It prefers its own head, so it will decapitate its victims before parasitizing them. It will also place the victim's head into the mimetic fluid that makes up its torso, and will lift its clothes to display the head in front of the victim's relatives.
"Your loved one has been properly preserved by me.”It says so.
