A mature male gorilla has the strength of ten men. Three big men may have the total strength of 6 normally-sized men, so they may have a much harder time trying to beat a gorilla down bare-handed. It's likely, in a fair fight, that the gorilla may win.
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 panther will not win since the gorilla will give a strong blow to the panther and the large ox will knock down the panther with its head. This leaves the large ox and the gorilla together in fighting. The large ox will win if it knocked the gorilla down with its head or at least gore it to death.
Most likely the gorilla, but the lynx, since it is a large cat like a lion or cougar, does have sharp claws and canines that it can and will use as a means of defense.
a silver back gorilla would win easily win!
Gorilla vs Elephant? The Elephant no contest
Probably the gorilla, unless the small man was armed with a gun.
A rhino could flip a gorilla
Even if the two men are larged sized, they will still be no match for the gorilla. A gorilla is as strong as ten men, and the two large men are as strong as 4 medium sized men. Two large men cannot beat down a gorilla bare handed. In this case, the gorilla will most likely win no matter what sized the two men are.
The gorilla will defeat the cattle-beast easily because the gorilla is more suited when it can stand and grab things.
A gorilla has no chance to fight a rhino.
The large ox because it would trample the gorilla to death.
The gorilla can win because of his mobility but likely the elephant unless the gorilla is smarter then the average gorilla. The elephant just needs a few pounces or 1 charge to win but the gorilla needs to be quick and persistent which is harder to do in a fight so my moneys on the elephant.
