8. Honey Badgers

The honey badger is renowned for its aggression and will take on opponents far larger than itself. Whether going up against a cobra or a cape buffalo, they are the ultimate brawlers, and if cornered, they will fight to the death, even with the lions. They are incredibly tough. Their thick hide makes them impervious to most attacks, such as bee stings, porcupine quills, and snake bites. Similarly, venom has little effect on them. When bitten by a venomous snake, a honey badger will merely fall asleep for a period and wake up later as if nothing happened.
