Hello Henk.

Male grizzly bear (750kg) vs 3 male lions (225kg each): This grizzly bear will be about 30% taller at the shoulder than each lion (for scaling purposes).  Grizzly bears don't encounter felines in the wild larger than a cougar, but lions don't encounter bears at all.  Grizzly bears are aggressive & powerful, and can easily injure a lion with a single paw swipe.  Lionesses are the primary hunters of the lion pride (the males defend the pride from other male lions), and work well as a team in subduing large animals.  3 male lions won't have the same level of teamwork as 3 lionesses, and that might be problematic against a huge grizzly bear.  The lions will need to attack from all sides to keep the bear's attention divided, and one lion will need to secure a throat bite while the bear is distracted.  3 lions would have a good chance of subduing a 750kg cape buffalo (because they can neutralize the horns with the right positioning), but a bear's weaponry (jaws & swiping paws) and flexibility (which is better than a bovid's) poses a different type of challenge that increases the difficulty level.  Bears have amazing stamina, and will continue to battle strongly after the lions succumb to fatigue.  If the male lions had the same level of teamwork as the females they might be favored, but the grizzly bear will likely injure one of the lions early on in the confrontation and create a more favorable numbers advantage for itself.  The male lions can certainly pull this off, but the durable bear weighs more than all 3 lions combined.  Slight edge to the male grizzly bear.  

Male polar bear (950kg) vs 3 male lions (225kg each): This polar bear will be about 40% taller at the shoulder than each lion.  Polar bears are extremely strong (battle walruses, pull large seals out of the water, punch holes through thick ice), and have very good endurance (can swim many miles without stopping).  Lions are fantastic predators that routinely tackle large prey items (cape buffalo, eland, zebra, wildebeest, etc.), but the females do most of the hunting and would have better teamwork than the males in a confrontation like this.  The only reasonable way for the lions to succeed here is to secure a throat bite, but it's highly unlikely the lions will be able penetrate the polar bear's defenses (bites & paw swipes) without being injured in the process.  This is similar to 3 lionesses taking on a polar bear (with a typical top-end weight).  This bear will have a massive strength advantage, and the lions will likely tire before they can make any meaningful headway.  A polar bear of this size will be too formidable for 3 male lions to overcome (even 4 might not succeed).  Male polar bear wins.

2 male grey wolves (50kg each) vs Female spotted hyena (85kg): Grey wolves work well as a team, so they can't be counted out here.  However, this is a huge spotted hyena with a bone-crushing bite that could seriously injure either wolf with a good chomp.  The wolves will be more nimble than the ungainly hyena, and will land more bites, but the counter-bite by the durable hyena will find its mark one one of the wolves before too much time elapses.  She won't come out unscathed, but the female spotted hyena should prevail more times than not.  Female spotted hyena wins.

Lioness (90kg) vs Female spotted hyena (100kg): Lionesses are among the most experienced combatants in the big cat world, and regularly tackle a variety of formidable adversaries.  A lioness is muscular, powerful, and agile.  It can use its agility & quickness to get into a favorable position to land a killing bite on the spotted hyena, and should be able to neutralize the hyena's crushing bite (its only weapon) on most occasions.  Hyenas are durable & difficult to kill, but a lioness has the tools to succeed (even against a larger hyena).  Lioness wins.

Male baboon (50kg) vs Average human male (85kg): Baboons are dangerous opponents due to their mobility, grabbing hands, and long, upper canines that can cause grievous injuries in a short amount of time.  The average human doesn't possess the required weaponry to combat this fierce animal, and won't have the mental fortitude to remain clear-headed while being attacked by those sharp teeth.  Baboons are familiar with conflict (dealing with a variety of dangerous animals), and will have a much better idea of what to do in this fight than an average human will.  Male baboon wins.

2 male humans (85kg each) vs Female spotted hyena (75kg): Hyenas are very durable animals that can withstand a lot of punishment from an attacker and continue to fight back.  They have great endurance, and have bone-crushing jaws that can inflict serious injury to a human.  Humans don't have the weaponry to effectively assault the hyena the same way a lion or a leopard does, and hyenas have survived attacks from these big cats on many occasions.  The humans would need to be highly skilled, physically strong/fit, & mentally prepared to have any chance at all (and even these attributes wouldn't guarantee victory).  One bite from the spotted hyena would change the mindset of the humans & effect their willingness to continue.  The hyena is just too strong & well armed for the humans to deal with.  Female spotted hyena wins.

Male grizzly bear (300kg) vs Male Siberian tiger (250kg): Grizzly bears are stocky, powerful bears.  They may be the most aggressive of all bears, and are about as formidable (pound-for-pound) as bears get.  Grizzly bears have muscular shoulder areas that enable them to generate a great deal of force with their paw swipes, and have tremendous endurance.  Siberian tigers are quick, agile, & well-armed (sharp teeth & claws).  Tigers have the killing experience all big cats do, and are practiced at dealing with Eurasian brown bears (which are similar to grizzlies).  Grizzly bears don't deal with felines larger than a cougar, but still have the tools to effectively battle a large tiger.  The tiger will be quicker in a swipe war, but the bear's swipes will have more strength.  The Siberian tiger can bring down large prey animals, but getting into a position to deliver a throat bite on a grizzly bear is more problematic because the bear's paws (and decent flexibility) enable it to counter effectively from almost any position.  Against a grizzly bear larger than itself, a Siberian tiger won't be able to overpower it in a grappling contest, and won't be able to secure a throat bite (on most occasions) before it becomes fatigued.  The mighty tiger has the ability to succeed, but the odds are against it at these weights.  Male grizzly bear wins.

Male doberman pinscher (40kg) vs Male sheep/ram (30kg): The Doberman Pinscher is a compact, muscular dog with a long, tapered muzzle.  It is fearless, and makes a great guard dog (and has been used by the police & the military).  Male sheep (rams) can come in different varieties, including domestic, bighorn, Anatolian, Barbary, etc.  A domestic sheep won't have the ability (or the temperament) to defend itself against a larger dog (even an untrained one).  A bighorn sheep would fare better, but it wouldn't have the speed to ram the Doberman with its horns on most occasions.  The bighorn sheep might be able to repel an untrained Doberman if it can keep it in front of it, but a trained Doberman (with this size advantage) will likely prevail.  This depends on the type of sheep & the level of training of the Doberman, but the canid will likely prevail in most scenarios with a 33% weight advantage.  Male Doberman Pinscher wins.

Best regards.

Questions regarding animal conflicts within realistic or unrealistic settings are welcome; my strength lies in medium-to-large species. Small animals (including birds of prey), prehistoric animals, sea creatures, and domestic dog breeds are usually within my scope, but to a lesser degree. I can't confidently answer hypothetical questions about human vs animal, arachnids, insects, or amphibians, but I am willing to field them nonetheless.


From a young age, I have been interested in animals. Starting with the original Mutual of Omaha's Wild Kingdom and World Book Encyclopedias, I have seen many animal shows and documentaries and have read multiple books on the subject. I have a solid understanding of the physiology of many animals and interspecies conflict in general.
