Researchers said that compared to grizzlies, polar bears are submissive. This is because grizzlies openly show their aggression in the way they walk and behave, which may have provoked the milder polar bears to flee instead of fighting.
Grizzly bears are by far one of the most aggressive and dangerous species of bear that you can encounter. They usually live in the northern and western regions of the US, as well as in Canada and Alaska.
Among all bear species, both the grizzly bear and polar bear take the crown as the strongest. Weighing more than around 800 pounds — the maximum recorded size is twice that figure — an individual male grizzly is equivalent to around five humans in strength … and even more when enraged.
North America's three bear species — black bears, grizzly bears and polar bears — don't typically live in the same place. But in Wapusk National Park, on the west coast of Hudson Bay in northern Manitoba, we caught all three bears on camera — for the first time.
With the bear's massive body, superior muscle, surprising speed and evolutionary armory, there really isn't any way a gorilla wins the fight. Every attempt it makes would be thwarted by at least one of these factors.
You may think that the polar bear has to have him beat on jaw power, but you would be wrong, there. While its a lot closer, the gorilla actually manages to beat out his foe with 1350 PSI on his jaw chomping power, although his teeth are flat like human teeth and intended for plants and fruit.
Punching a grizzly, even from a gorilla, would do minimal damage. The neck is too thick to choke or snap. With smaller adversaries a gorilla could pick them up, smash them around, and even rip off a limb with its strength.

Do not play dead. Direct punches and kicks at the bear's face, and use any weapon like rocks, branches, or bear spray to defend yourself. If a grizzly/brown bear charges and attacks you, PLAY DEAD. Do not fight back!
The bear has also been known to bite its prey in the back of the neck to kill it. The bear begins eating its prey from the chest or hip regions. The animal's entrails are also among the first parts to be eaten. The bear has a very special way of storing the carcass.
