Animalistic Abomination
It's big, powerful and nasty. It's not humanoid, but familiar all the same.
This trope is for Eldritch Abominations that either naturally resemble (somewhat) ordinary animals, or else possess Animorphism and spend a good deal of time in the animal form. A Draconic Abomination takes the form of a dragon in particular. If the abomination has similar behavior to its non-eldritch counterparts, it might also be an Almighty Idiot.
