The gorilla would win on land. It can break the crocodile's jaw or shut it tight. In water, the crocodile would bite the gorilla and drag it underwater.
A rhino could flip a gorilla
A gorilla has no chance to fight a rhino.
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.
Elephant .
a bear

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.
Gorilla vs Elephant? The Elephant no contest
Possibly the lioness, but a lioness would only hunt a gorilla down if their are no other prey to kill.
