Possibly the gorilla, but fights between these animals are extremely rare.
a silver back gorilla would win easily win!
Elephant .
Gorilla vs Elephant? The Elephant no contest

Probably the gorilla, unless the small man was armed with a gun.
The gorilla would win because it would grab the panther and snap its neck.
One would think that 5 dogs would win, hands down. The gorilla would not stand chances against these dogs since 5 dogs are good enough to kill an adult gorilla. Even if the gorilla threw stones or sticks, the dogs would charge at the gorilla and bite it down.
The Gorilla. More aggressive,better armed,and has the ability to stand on 2 legs and punch.
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.
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 gorilla will defeat the cattle-beast easily because the gorilla is more suited when it can stand and grab things.
