Most of the time, it wouldn't. The black bear is bigger (700 lbs vs 550 lbs), stronger (bears are, pound for pound, the strongest of the order Carnivora, an order containing both bears and felines) and smarter (if food is a reward, they can even learn faster than chimpanzees) than the lion. The black bear has stronger forequarters (it can flip a flat-shaped rock more than twice its own weight) and jaws (1500 lbs vs 1000 lbs, the black bear uses its bite to rip through wood). The lion is slightly faster (30 mph vs 35 mph) but the black bear is better designed for a fight. Here's an excerpt from The Great Bear Almanac...
"There is also a vague account of a circus (African) lion that jumped an American black bear during an act. The fight was fierce and both combatants were injured, but the lion's injuries were of the extent that it had to be destroyed."
The black bear would win this fight. A black bear has more muscles and a bad aggression with sharper claws and teeth.
Probably the black bear.
The black bear would win.
Any Rhino from the black rhino and up would win against any Bear. How ever a Grizzly bear,polar Bear,or Kodiak bear would stand a chance against a rhino of the smaller species such as the Javan Rhino or Sumatran Rhino.
The giant black bear would win, but it would be injured.
It depends on who is bigger. If the black bear happened to kill the lion, the black bear would get badly injured.
Black bears dominate over cougars. A grizzly bear would destroy a cougar.
The black bear would win because it is heavier and can stand up.
The two black bears would win the fight because they together weigh as much as a grizzly bear, and have bad aggressions. The grizzly bear would injure the two black bears after the two black bears killed the grizzly bear.
The grizzly bear would still win the fight because it has a larger size and stronger claws and teeth.
Black bears usually flee from the bigger, stronger brown bear.
The bear probably would fight with its paws and would try to attack it but if it was bigger than it it might fight the animal or animals until they bleed
