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.
With three animals put in a fight, it is very hard to say. It's likely that the panther may not win since the large gnu would gore the panther to death and the gorilla would hold on the panther's throat. This leaves us with the gorilla and the large gnu. In this situation, a gnu is not as big and strong as an ox or a bull is, plus it would run away from attacks. The gorilla has powerful hands, strong canines, and thick chest muscles, while the large gnu has those sharp horns, hooves, and some body muscles. The large gnu does not have enough power to stomp or trample the gorilla to death unlike an ox, but it could try charging at it. Thus, this would make the gorilla want to fight back by holding on the gnu's head and biting it with its teeth. Later, the gnu might want to charge back if it survived.
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.
a mountain gorilla would win because there bulky and super strong it would win with a slam or punch
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.
