It’s true that the honey badger has the Guinness Book of World Records title of "World's Most Fearless Creature," but they’re more than just audacious: they’re downright mean. They’re invasive and eager to pick a fight—even with a porcupine. But that doesn’t mean they’re invincible. Hyenas, lions, leopards and pythons are all foes (as are humans), but if those are considered your only enemies, you’re probably incredibly tough.
