Probably the black bear.
A lot of people will say lion , however they are wrong because they are just stupid lion fans that know nothing about a tiger's advantages. The tiger will win because it is stronger! heavier, more agile, bigger, has longer canines, is a better fighter, is smarter, and is not lazy and waits for females to hunt. Tigers rule and lions suck
The black bear would win this fight. A black bear has more muscles and a bad aggression with sharper claws and teeth.
The black bear would win.
The giant black bear would win, but it would be injured.
The grizzly bear can kill a lion or a lioness with swipes of those powerful, sharp claws and strong swats. A large lion and a large lioness working together might bring down the grizzly bear depending on how big is the grizzly bear. Since grizzly bears have such big size and powerful claws that could kill a large lion or large lioness, it is quite strong enough to kill both of them. In this case, the grizzly bear would kill the large lioness and the large lion, but might get wounded.
It depends on who is bigger. If the black bear happened to kill the lion, the black bear would get badly injured.
A lioness can kill a black bear because it has great hunting skills that could bring down the black bear. It may also be a draw between an experienced lioness and a male black bear. Black bears have weight advantages, but lionesses have better hunting skills. Lionesses weigh 400 pounds, while black bears weigh 600 pounds. For a brown bear or a polar bear, it is a far different story.
Black bears dominate over cougars. A grizzly bear would destroy a cougar.
No. A lioness and a polar bear would not meet because one (the lioness) lives in a hot, arid environment and the other (being the polar bear) lives in a very cold dry environment. However, if they did meet, the polar bear may be able to kill the lioness with one single swipe to the head. The lioness, on the other hand, would need other lions and lionesses in order to bring down the polar bear.
The black bear would win because it is heavier and can stand up.
this would never since they don't live in the same continents
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.
