Could a pro ufc fighter beat a gorrila in a fist fight?

Negative

Hell no. A gorilla can bench press almost a metric ton and their skull is several inches thick. A human will either be killed or severely mutilated

A gorilla won't follow rules. UFC fighters are vastly over-rated. Most have no chance against an adult gorilla.

No.

Get real. A gorilla could literaly tear any man to pieces. You don't understand how strong those animals are.

Yes, maybe. If it is a fist fight only. But i doubt that only attack thru punches

Not a full-grown gorilla.

If the gorilla was asleep, maybe. Otherwise... the term bloodbath comes to mind, and it wouldn't be the gorilla bleeding.

A UFC heavyweight would struggle against a chimpanzee, which is less than 5 feet tall, because it is far stronger than a human so imagine how much stronger a 6 feet gorilla must be. Straight fist fight the UFC might land blows but a gorilla's arms are so much longer that would be unlikely and a gorilla wouldn't just stand and trade anyway. It'd overpower the guy whatever way it wants to.

Even a ufc heavyweight known for his punching power has very slim chance of beating a gorrila. But a boxer like Tyson in his prime can beat a gorrila in fist fight cause gorrila lacks technical skills
