Well, if I may…!
1): The MarrowJaw:
A clan, be it Orcs, Trolls, Goblins or all three at once, who treat eating their victims very seriously. Their entire culture is based on culinary pursuits, and they have developed many advanced techniques in properly preparing their prey. Status, wealth, and even political power hinges on how well one can fatten up some hapless human/elf/dwarf/whatever and make them taste good.
As such, they will often be more focused on immobilizing you than just straight up killing you whenever you encounter them, with many of their magic users having spells specifically to pack on pounds. Can’t let a kill go to waste!
2): AzureFolk:
A peculiar species of azure-skinned pretty-boys/girls, and living fossils from the Before-Times. Back then, they were wood elves, seeking a direct connection to nature itself. They specifically conducted research on blueberry bushes for this end, but under circumstances lost to time, these experiments permanently transformed their kind. They are now constantly blowing up into blueberries, to the point of exploding if they don’t transfer the juices into another being. Many elves burst during the initial calamity, and now they are a desperate tribal lot, desperate to escape the cruel fate imposed by their hubris.
They typically have farms of animals that they dump juices into where which they are often found, but they will be more than happy to attack adventurers on sight.
3): Man-Mountains:
GIANTS. They can be of any race and of any gender, but they all essentially fit under one umbrella; impossibly large, impossibly fat, and quite prone to wanton violence.
Their goal is to eat. Plants, animals, people; if it’s edible, it goes right into their massive gullet. They will gladly raid entire cities alone to get their desired fill, and typically have the raw strength to back it up.
The average Mountain won’t be a lot larger than an elephant, but some can reach heights equal to castles.
And while they typically attack things smaller than themselves, they will be quick to attack each other on sight. They themselves are quite a lot of meat!
4): Mimic Supper:
Dinner table mimics! Typically hiding in abandoned manors or castles, they disguise themselves as fresh dinner for any poor dipstick who gets it into their head to eat. When sufficiently fattened, they become the main course.
I’ll be more than happy to add onto this later, of course…
