Bear takes this easily. They are much bigger and stronger. A Kodiak bear can crush the gorilla's skull.
Definitely the bear would win.
a bear
The black bear would win.
Since kodiak brown bears are a huge subspecies of brown bear, and a grizzly is a smaller subspecies of brown bear, a kodiak would win (assuming an average sized individuals from each was fighting). Average grizzlies weight around 400-500 pounds, while Kodiak's can weight around 1,000.
The kodiak bear would beat any type of crocodile on land as long as it sees the crocodile. Kodiak bears are very large and very powerful bears.
The bear, probably, but the gorilla would make him earn it, as they are very powerful.
The Polar bear. It is larger, much more carnivorous, more beastly, and stronger than a grizzly bear or a kodiak bear.
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.
depends on the environment
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.
The ox would win if it is healthy and strong with a gore of the horns on the chest. But is likely that it would get pretty injured.
