Definitely the bear would win.
depends on the environment
Polar bear much bigger and stronger
a bear
The black bear would win.
Bear takes this easily. They are much bigger and stronger. A Kodiak bear can crush the gorilla's skull.
The bear, probably, but the gorilla would make him earn it, as they are very powerful.
One on one, bear wins easily. Three gorillas would be even.
Bear. Bears are predatory by nature. Gorillas are not, and thus can be seen as prey by a bear.
Definitely the bear would win. A gorilla would only throw stones or sticks, and punch its chests to frighten off the bear. But the bear would swat the gorilla to death with its muscles and sharp claws. But if the gorilla threw stones or sticks at the bear, it would have a chance to injure it. Bears have larger canines, heavier weight, and stronger muscles with very powerful sharp, large claws. A gorilla does not punch or smash like humans do, which makes the bear kill the gorilla without too much pain.
Because of size, the bear would win. The bear also has claws and a better bite for killing than the gorilla. This would cause the grizzly to be able to hurt the gorilla better. If the gorilla was the same size as the grizzly, it would be a different matter. The gorilla would certainly be stronger in that case.
The grizzly bear would win. But Muhammad Ali, in his prime, could have beaten all three beasts.
3 wolves will win if the gorilla gets frightened, and 3 wolves are enough to take down a lion. A silverback gorilla is pretty good at killing a wild dog, but 3 wolves will get the gorilla at the end.
