Gorillas normally do not wish to fight those animals that are plant eaters like itself. A gorilla would quickly learn that a horse is an animal to keep its distance from after receiving a good kick or sharp bite if it got too close to it. And horses, unless cornered, prefer to take flight rather than fight, and would normally run away if they see a strange animal like a gorilla charging it. So no one would win or lose.
a silver back gorilla would win easily 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.
Gorilla vs Elephant? The Elephant no contest
gorilla
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.
The horse.
Probably the gorilla, unless the small man was armed with a gun.
A rhino could flip a gorilla
A gorilla has no chance to fight a rhino.
The gorilla will defeat the cattle-beast easily because the gorilla is more suited when it can stand and grab things.
Elephant .
Gorillas are apes.
