What animal is stronger a bear leopard cheetah?

I first thought that a crocodile would win the fight but it was actually a bear, I found out this from YouTube. At any point, if the bear scratches the crocodile and it turns over, the crocodile is in danger. The bear would just scratch the crocodile on its stomach ( A crocodile stomach is very delacte means soft ) a few times then it would die. So the bear WINS!!!
