Assuming that they fought (the two have no common ecological habitats), either could win.
The bear is much heavier and stronger, and has sharp, deadly claws. However, the lion is more agile and a large lion could possibly kill a bear if it inflicted injury to the bear's neck. There are instances of a wolf pack killing a bear in this way.
There are records of Siberian tigers, a cat somewhat larger than lions, killing brown bears.
that's hard but I'd say the lion because they are more ferocious.
Lions and grizzly bears do not live on the same continents so would never meet in nature.
a polar bear will most likely win in a fight against a grizzly bear
The grizzly bear would probably win
The grizzly bear would still win the fight because it has a larger size and stronger claws and teeth.
The grizzly bear would win. But Muhammad Ali, in his prime, could have beaten all three beasts.
Again, the grizzly bear, but it could die from the hot weather in africa.
The two black bears would win the fight because they together weigh as much as a grizzly bear, and have bad aggressions. The grizzly bear would injure the two black bears after the two black bears killed the grizzly bear.
grizzly bear
The grizzly bear would maul the crocodile on land if the crocodile tried to attack the grizzly bear. Grizzly bears have strengths to kill a crocodile, no matter what species. In water, the crocodile may win.
Lion would be killed. Grizzly bear would be more powerful and stronger.
Strength triumphs over stealth in some encounters. If the cougar were to pounce on the grizzly, the grizzly would turn the tables on the cougar and grab it. Then it would kill the cougar with one bite to the neck. So my bets are on the grizzly bear.
The Polar bear. It is larger, much more carnivorous, more beastly, and stronger than a grizzly bear or a kodiak bear.
the grizzly would tear the golden eagle to shreds because the grizzly would get the birds foot and kill him winner grizzly bear
