The bear, probably, but the gorilla would make him earn it, as they are very powerful.
grizzly would quite easily. pound for pound they are much stronger and more aggressive. they also have claws and more powerful bite force.
The grizzly bear would win. But Muhammad Ali, in his prime, could have beaten all three beasts.
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.
This is a very funny question and quite thoughtful. A gorilla probably would not fight with the giraffe and the giraffe would not even be afraid of a gorilla. Giraffe's have no natural enemies and neither do gorillas. I would like to see a matchup between a polar bear and a grizzly bear - now that could be a war.
A rhino could flip a gorilla
A grizzly bear to be sure. While the silverback is highly aggressive and strong, the grizzly wins hands down due in large part to its weight, powerful bite, and most deadly of all: his paws.
A gorilla has no chance to fight a rhino.
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.
Probably the gorilla, as cougars do not like to fight an animal that will stand up to it and be prepared to fight it.
The grizzly would most obviousley win. It is a carnivore, and so it is a better fighter than the gorilla. And Gorillas only have hands like humans (though they are not nearly as pathetic as a human) And a bear has teeth, claws, and an attitude to match.
* if a gorilla ever got into a fight with a pack of bamboons, most likely the bamboons would, but it is more of a 50% 50% chance in the fight
The grizzly bear would probably win
