, or Gulo gulo, is actually more closely related to weasels. But it's bulk allows it to bring down prey as big as a moose. That's what gave Gulo gulo a ferocious reputation. It can also use its musk to drive bears, Cougars, and wolves from their kills. Musk is the same stuff skunks spray, but they use it as a defense. Even though the Wolverine is ferocious, it is no match for man.
