How about we get mythological up in here? First off, there's the Catoblepas, which was what easily scared ancient Greeks interpreted wildebeest as. Long neck, poison breath, harmful stare, that's practically a entire moveset by itself.

Next, we have the Yale. No, not the university, the creature. Basically the Yale is an antelope that has horns that can move around like spare limbs. If that doesn't sound special, I don't know what to say to you.

And lastly, we have the Crocatta, which is basically a hooved hyena. But it's not just a hyena with strange footwear: it can also mimic others voices (setting up fights in the story, perhaps?) and use shadow magic to strike it's enemies dumb. A good choice for an final boss in my opinion.
