Sure. If an African Buffalo can kill a lion, then so could a bull.
There are a couple ways this could be possible. Obviously, a horse could easily kill small or younger cubs by stomping them to death. A horse's best chance at killing an adult lion would be if it managed to land a well aimed kick to the head. The head tends to be a sensitive body part to big cats, as giraffes often always kill lions with a single kick to this area..
If the lion is in a resting or a lazy mode, the man can kill the lion if he was quick to run up to the lion before the lion attacks.
i think it can not
Probably not, but anything in nature could happen. A wolverine would only kill a lion if it was starving, had to feed its' family, etc, but not just to kill a lion. if he had to
Yes, a polar bear could kill a lion. A polar bear weighs 1800 pounds, is 13 ft long, and has stronger muscles than a lion, and its sharp claws could kill two lions at a time. A lion weighs 550 pounds and is 6.5 ft long.
No. A single lion would be able to kill a buffalo calf, but not a fully grown adult.
No but a sparrow hawk can
it is impossible for them to meet so they would both win
One single lion to a bull? Definitely not! A cape buffalo will make a lion turn tail and run, and so could a bull.
A lion could easily escape a bear, and a lion would not be easy for a bear to kill.
Hugely unlikely considering that a lion is several times bigger and heavier.
