Can a gorilla kill a king cobra?

No. A king cobra has venom that it sprays into it's opponent's eyes at quite a distance, and can do so without the gorilla even being able to touch it. This venom will permanently blind a gorilla, and a single bite will kill it. A gorilla does not have such a weapon, only speed and strength. A blind gorilla is a gorilla that won't have a chance in a battle between it and a king cobra!
