An elephant would beat a bear in a fight. Even though we have granted this hypothetical bear the best features of all the various species, the fact remains that they cannot do enough damage to kill an adult elephant.
Aside from humans, lions are the only predators powerful enough to kill an elephant. The males, being 50% heavier than the females, are especially suited to the task. It typically takes seven lionesses to kill an elephant, but just two males could do the same.
An elephant would win in a polar bear vs elephant fight. The elephant is simply too large for the bear to do anything meaningful against. The polar bear can't exactly leap onto an elephant's back, so it would only be able to attack the elephant's legs and stomach area.
An unarmed human could not bear a grizzly bear in a fight.
Humans cannot do serious harm to a grizzly bear. It is strongly advised that you do not get near grizzly bears.
Although a silverback gorilla is very fast, quite strong, and has a longer arm span, it is unlikely that a silverback could defeat the much larger and faster grizzly bear in a fair fight. The one advantage that a Silverback might have is the enormous strength of its muscles.
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.
The strongest land animal in the world is the elephant. The typical Asian elephant has 100,000 muscles and tendons arranged along the length of the trunk, enabling it to lift almost 800 pounds. The gorilla, the strongest as well as largest primate on the planet, is at least six times stronger than the average human.
In the battle of the grizzly bear vs tiger, a Siberian tiger would win a fight against a grizzly bear. The Siberian tiger is an ambush predator, and it's the only big cat that comes close to the grizzly bear in terms of size and power.
An elephant would win in a fight against a gorilla. Gorillas are certainly powerful and smart animals, but they lack any definitive means of killing an elephant. Unless they happened upon an elephant lying down and managed to inflict severe bites to them, a gorilla simply would not stand a chance.
Carnivores (meat eaters) such as lions, hyenas, and crocodiles may prey upon young, sick, orphaned, or injured elephants. Humans are the greatest threat to all elephant populations.
Elephants have no natural enemies, but hyenas and lions are classified as elephant predators. They prey on young elephants when there is nothing else to eat. The entire herd protects the babies.
In an elephant vs hippo fight, the elephant is going to win. Assuming both creatures are fully grown adults, the elephant is just too big for the hippo to handle.
Would it surprise you to know that an adult bear has almost no predators? Bears are large and can be quite intimidating so they don't have many enemies. Their biggest enemies are humans and each other. It's the cubs and the smaller females that have to watch out.
On land, the bear could possibly win a fight if it managed to flip over a crocodile and attack its underside. However, this fight would not be over quickly: the bear would need to do a lot of damage to finally kill the reptile.
A bear would win a fight against a lion. Bears have the advantage in just about every aspect, from size to offensive capabilities. The only time that a lion would win is if it managed to sneak up and ambush a bear, leaping onto it and biting into its head with such power that it shattered the skill.
However, grizzly bears are tougher than polar bears as they possess stronger and longer claws and an elongated skull with sharp and long canines that can completely separate the flesh from bone.
Although the gorilla is strong, the fact is that it could not stop 600 pounds of charging muscle and teeth. Gorillas lack the sensory capabilities to notice a stalking tiger before it launches its fatal attack. If the two creatures met on an open field, the tiger would still have the advantage in the fight.
The gorilla and grizzly have a relatively similar bite strength, but the bear's build makes it harder for a gorilla's bite to be equally as effective. The gorilla's biggest advantage is its spry movement, whereas the grizzly's primary advantage is its claws. The grizzly is larger, but the gorilla is stronger.
The honey badger has been called the world's most fearless animal because it doesn't hesitate to attack animals much larger than itself- even lions and crocodiles! Honey badgers are found in arid grasslands and savannahs and even rainforests. They live in burrows in the ground.
A hippo would win a fight against a polar bear.
The hippo is larger, stronger, has better offensive powers and a defense that would allow it to last longer in a battle than a polar bear.
Put more bluntly, when polar bears and grizzly bears are both competing for food, it is the polar bears that are more likely to walk away from conflict and leave the prize for grizzly bears. The bottom line: in a fight between a polar bear and a grizzly bear, the grizzly bear reigns supreme.
They are both highly aggressive creatures, so a prolonged fight could be brutal. Even then, the lion would probably come out on top, making up for its relative lack of stamina with sheer power. A lion has a good chance of killing a gorilla in a one-on-one fight. The only thing is that a lion rarely fights alone.
