Black bear and lion fight who is powerful

Lion fight is to rely on the group Lions go out are generally a family or a group, if it is said that a single lion and adult bears fight, I see the lion's chances of victory is very small, the reason why the lion is called the King of the Beasts, that is also from the ancient times to say that the lion such a large cat is really the most united and most courageous on the forest or prairie is also a very smart animal bear courage is also a sign that the bear is indeed very brave and also very strong, the bear is very brave. It's very strong.
