Given the circumstances i would think it could. On the other hand given the circumstances a very large python may be able to kill a grizzly.
Lions, especially if they are females from the same pride. The grizzly bear can defeat and kill the ox if it avoided its horns and head, but the lions will get it after the grizzly bear gets injury by the ox's body strength. If the grizzly bear attacked the 4 lions, the grizzly bear will have a chance to win because its big claws can kill 2 lions if it was strong enough to. After the lions get killed, the grizzly bear might get injured, and the ox can kill it with ease.
The grizzly bear can kill a lion or a lioness with swipes of those powerful, sharp claws and strong swats. A large lion and a large lioness working together might bring down the grizzly bear depending on how big is the grizzly bear. Since grizzly bears have such big size and powerful claws that could kill a large lion or large lioness, it is quite strong enough to kill both of them. In this case, the grizzly bear would kill the large lioness and the large lion, but might get wounded.
Yes. A bull moose could even kill a grizzly bear.
Yes, if the kodiak bear avoided the moose's hooves and antlers (if it is a bull moose). Even a grizzly bear or an alaskan brown bear could kill a bull moose, but not when it is on the rut.
It pretty much depends where you shoot him and 3,4,5,6 shots
