Nundu

It's a Nundu (a very large "leopard" whose breath can decimate entire villages), moving in for the kill (those tiny brown things are huts).

I didn't know whether to upload this under "Fanart" or "Fantasy"...the first place I heard a Nundu described was in J. K. Rowling's/Newt Scamander's Fantastic Beasts and Where to Find Them , but I guess Nundus have been around longer than Harry Potter, and therefore can pass as "just another imaginary critter."
