A wolverine, in theory, doesn’t really have any natural predators. In the comics, some would say it’s Victor Creed whose mutant abilities, rapid healing factor, razor-sharp fangs and claws, and superhuman senses, make him one of the most deadly mercenary assassins in the world who goes by the name Sabretooth. Of course, that’s silly.
It’s really Erik Lehnsherr, also known as Magneto who poses an existential threat to the world. Former University of Michigan guard Patrick Omameh will tell you it’s actually a very large shrub-like plant with inedible, mildly toxic, nuts called the Buckeye.
