Hello David.

1) Tyrannosaurus rex vs Formica rufa (parity): Tyrannosuarus rex was a formidable carnivore, with tremendously strong jaws armed with dagger-like teeth.  Formica rufa (red wood ant) is an ant capable of spraying formic acid to defend itself.  Ants can lift/move objects many times their own weight.  The ant's body will be not be as durable as the Tyrannosaurus', but its strength and quickness will be much greater (assuming its abilities & attributes remain the same in relation to its body size).  The bite of the Tyrannosaurus will be strong enough to remove parts of the ant and kill it if it is applied in the right location, but the ant will likely subdue the theropod before that happens.  Even without the use of its acid, the ant will have a good chance to succeed.  Formica rufa wins.

2) Utahraptor vs Formica rufa (parity): The Utahraptor was a dangerous, uniquely-armed theropod (jaws with sharp teeth, clawed forelimbs for grabbing, clawed hindlimbs for slashing) with good quickness and leaping ability.  With its more diversified offense (and less radical scaling of its size), the Utahraptor will have a better chance to defeat the Formica rufa than the Tyrannosaurus rex will.  However, the Formica rufa will still be much stronger and quicker.  The ant may need to rely upon its formic acid to repel/subdue the Utahraptor, but it should get the job done.  Formica rufa wins.


1) 300kg Barbary lion vs 5x 20kg Haast's eagle: The Haast's eagle was able to dispatch 200kg+ moas (giant ostrich-like bird) with an aerial attack because the moas had no way to prevent this.  Such is not the case with a Barbary lion.  While a precise strike of the bird's talons to a vulnerable spot on the lion might cause trouble for the cat, the more probably outcome will be the Barbary lion (speed, agility, fast reflexes, jaws & claws) swiping the birds out of the air as they came into range.  Barbary lion wins.

2) 2.5t Albertosaurus vs 4x 300kg Barbary lion: Albertosaurus was a lightly-built theropod (an adaptation for chasing prey items) with large jaws and sharp teeth.  Lions work well in unison to overpower large prey items, but Albertosaurus will weigh 7 1/2 times as much as each lion.  The key to this battle will be the fact that the dinosaur will be able to dispatch a single lion with one bite (and should get an opportunity to do so if the lions leap upon it) and the lions will need time to wear down Albertosaurus with biting & clawing.  A "throat bite" kill by the lions will be very difficult with an animal this big.  Albertosaurus wins.

3) Allosaurus (great specimen 4.5t 11m) vs 6x 300kg Barbary lion: The Allosaurus will weigh over 13 1/2 times as much as each Barbary lion.  Allosaurus was a predator capable of removing large chunks of flesh from victims with its bite.  As with the last matchup, the Allosaurus will be able to quickly kill any lion that gets too close to its business end, and the lions will need a lot of time (and energy) to create the damage needed to overcome this huge reptile.  The lions aren't without hope, but the odds will be against them.  Allosaurus wins.

3a) 300kg Barbary lion vs 5x 60kg Rottweiler: The Barbary lion will have the typical big cat attributes (speed, agility, jaws & claws, killing know-how, etc.) to bring to this battle.  Rottweilers are powerful, courageous dogs with broad heads and strong jaws.  5 of them probably won't strategize like a pack of wolves will, and will be hard-pressed to get past the weaponry & fast reflexes of the lion.  Male African lions are usually more than a match for 5 spotted hyenas (which, to be clear, aren't canids), and spotted hyenas are much more formidable than any Rottweiler.  Rottweilers are great guard dogs, but there are many dog breeds that are better combatants (pound-for-pound).  The lion will dispatch the Rottweilers rather quickly.  Barbary lion wins.

3b) 300kg Barbary lion vs 2x 100kg Deynonychus: Deinonychus was much like a smaller version of Utahraptor, with similar attributes & abilities.  With animals working together as a team, the effectiveness is often greater than the sum of their parts.  However, with this matchup, the Barbary lion will have the quickness, agility, and weaponry to combat the attacking theropods.  It can readily overpower a single Deinonychus with forepaw usage and kill it with a bite, but will need to content with the other one attacking from behind (which will complicate things).  The lion's ability to make quick turns and quick swipes will be crucial.  It won't win every time, but should win most of the time.  Barbary lion wins.

4) 6t Elasmotherium vs 7t Acrocanthosarus: Elasmotherium was a rhinoceros-like mammal with a long sword-like horn protruding from its forehead.  Its legs were long enough to give it decent agility & lateral quickness.  Acrocanthosaurus was a large theropod with strong jaws, sharp teeth, and a ridge along its back (kind of like the sail of Spinosaurus, but not nearly as tall).  It commonly fed upon sauropods.  In this battle, the horn of Elasmotherium will be able to seriously injure the Acrocanthosaurus with a solid lunge, but its lack of armor will make it vulnerable to the bite of the carnivore.  Close fight, but with its weight advantage, the Acrocanthosaurus will be large enough to challenge the herbivore on most occasions.  Depends somewhat on who gets the first strike in, but edge to Acrocanthosaurus.

5) 2x 6t Elasmotherium vs 10t Tyrannosaurus rex: This will depend on whether or not the Elasmotherium tandem cooperates to overcome the Tyrannosaurus.  If the Elasmotheriums strategize, one can impale the Tyrannosuarus (seriously wounding it) while the theropod is concentrating on the other one, but there's no guarantee they'll do this.  They have no armor to protect them from the Tyrannosaurus' huge bite, and the Tyrannosaurus is accustomed to dealing with ceratopsians (herbivorous dinosaurs that typically had sharp horns & protective neck frills).  The Elasmotheriums will likely drive the Tyrannosaurus away if they stick together, but will probably be picked off if they scatter.  A Tyrannosaurus of this size will have the ability to bite a vulnerable area of an Elasmotherium before the horn makes contact with it, and that may be decisive.  Can go either way depending on how each party reacts, but my money's on the Tyrannosaurus prevailing more times than not only because I don't think the Elasmotheriums will form a strategy.  Edge to Tyrannosaurus.

6) 130kg Brock Lesnar vs 20kg Haast's eagle: A Haast's eagle can certainly kill a human with an aerial attack if the human isn't aware of its approach, but one aware of its presence will have a chance to survive.  Brock Lesnar is physically superior to most humans, and has the strength to grab a Haast's eagle and subdue it if he has the mental toughness to deal with the injuries he will receive doing so.  Birds of prey aren't built to engage in terrestrial combat with other large animals (they are stealthy ambush hunters, mostly), especially ones that can fight back.  The body of the Haast's eagle won't be durable enough to withstand the offense Lesnar can apply to it once it is grabbed, and its unlikely the talons will do enough damage initially to incapacitate a strong, 130kg human with the benefit of a secretive ambush.  Edge to Brock Lesnar.

7) 10t Tyrannosaurus rex vs 10t Deynosuchus (land): Deinosuchus resembled a huge alligator/crocodile, and had similar attributes/abilities.  Tyrannosaurus was a fearsome terrestrial predator, but Deinosuchus was an impressive aquatic one.  On land the Deinosuchus will be limited in mobility & stamina (maybe not to the same degree as modern crocodilians, but we're not sure), but will still have an armored body to help protect it from the bite of the Tyrannosaurus.  Still, there are areas on the body of Deinosuchus that can be breached by the huge bite of the Tyrannosaurus.  Deinosuchus was likely capable of making the same quick movements in short bursts like modern crocodilians can do (like rushing forward or moving their heads/jaws swiftly from side-to-side) and the Tyrannosaurus will have problems dealing with being latched onto by the massive jaws of Deinosuchus.  On land, the Deinosuchus won't have as effective means as the Tyrannosaurus to finish the fight, and its lack of mobility/stamina might leave it vulnerable as the battle progresses.  Edge to Tyrannosaurus.

8) 10t Tyrannosaurus rex vs 10t Deynosuchus (2m deep water): The Deinosuchus will operate more effectively in the water.  Its mobility will increase a great deal, as well as its stamina.  The Tyrannosaurus will lose some of its lateral quickness with water reaching almost 1/3 the way up its body, and it won't be able to easily apply its bite where it wants to.  Deinosuchus will be capable of making powerful movements, and it will be able to lunge rapidly to seize the dinosaur in its jaws (a modern crocodile can lunge out of the water at 12m/s for a comparison) and apply a great deal of torque (twisting force) to subdue the theropod.  It's rare to find a terrestrial animal (modern or prehistoric) that can enter the water to battle a crocodilian of the same weight and come out on top.  Deinosuchus wins.

9) 20kg Eurasian badger vs 18kg caracal: Eurasian badgers are hardy mustelids with strong limbs (and claws for digging) and powerful jaws.  Caracals are lynx-like felids with athletic bodies.  Caracals are quick, agile, and have sharp claws on their limbs.  A battle between these 2 animals will be close, but the badger's more durable build will make it a tough adversary.  The caracal will be quicker, but speed won't be a great factor at close quarters.  Realistically, the badger will drive the caracal away, and in a serious battle the caracal won't make enough headway with its offense before breaking off its attack.  Once the badger lands a bite or two, the caracal will likely lose interest.  A caracal has the tools to kill a badger, but won't risk it.  Edge to Eurasian badger.

10) 5t Megatherium vs 4x 600kg Utahraptor: Megatherium was a huge ground sloth standing taller than a giraffe and having huge forelimbs armed with claws.  It also had protective hide (pieces of bone that formed an armor like chain mail) that kept it safe from many predators.  Utahraptor's sickle-shaped hindclaws were sharp, and made effective killing tools.  The Utahraptors' agility and jumping ability will enable them to attach themselves readily to a part of Megatherium's body, and the plodding mammal won't be quick enough to keep this from happening.  It will take the Utahraptors a long time to breach the hide of the Megatherium, and they may not think the effort is worth the time, but they are capable of eventually killing the giant sloth.  A stalemate might result, but Megatherium won't be able to use its greater size and strength to its advantage to swing things in its favor.  A Utahraptor that gets killed by a Megatherium will be a careless one.  The Megatherium might be able to swipe the theropods away from certain areas on its body (where its forelimbs can reach), but the crafty Utahraptors will probably stay safely out of the way as they engage.  Overall edge to Utahraptors.

11) 5t Megatherium vs 15x 100kg Deynonychus: The Megatherium will weigh 45 times as much as each Deinonychus.  As with the Utahraptor matchup, the Megatherium won't be able to prevent the Deinonychus pack from leaping upon it and securing places to attack.  The Deinonychuses, however, won't be able to create the same level of damage as the larger Utahraptors will be able to.  It will take them a very long time to breach the tough armored hide of Megatherium, but Megatherium won't be able to effectively prevent the attempt.  Megatherium may be able to swat a few of them away from time-to-time if they attack from the front, but it won't be able to repel all 15 of them.  Realistically, the Deinonychuses won't spend the time and effort trying to overcome this huge beast (but I won't rule it out), and a stalemate will likely ensue in most encounters.  Stalemate; overall edge to the Deinonychuses.

Human vs animals

1) 15x Brock Lesnar (armed with steel baton) vs 500kg grizzly bear: The grizzly bear will be much stronger (pound-for-pound) than Brock Lesnar, and have much greater absolute strength while weighing almost 4 times as much.  Its durability & endurance will be superior as well.  The grizzly bear's weaponry (jaws, swiping paws, claws) will easily dispatch a single Brock Lesnar, but one of the 15 of them may strike a vulnerable spot (head, spine) on the bear to turn the tide.  The Brock Lesnars will need to rely on strike placement over strike force, and their precision may not be great while dealing with an angry grizzly bear.  If the Lesnars attack without regard to their own safety to ensure a finishing blow will eventually be landed, they will have a decent chance (at the expense of the survival of many of them).  If the bear becomes confused (never having dealt with this type of attack), it may not function as it needs to in order to adequately protect itself.  Could go either way depending on the mindset of each party.  Maybe 50/50.

2) 8x Brock Lesnar (armed with steel baton) vs 200kg Indian lion: A lion will be quicker and more agile than the grizzly bear, but won't be as durable.  It will subdue many of the Brocks with paw swipes & bites, but a precise strike will spell trouble for it.  As with the last matchup, the mindset of each party will be key.  Both can win, but each encounter will be different.  A lion fighting back optimally will likely prevail, a lion not doing so may not prevail (with many Lesnars lost either way).  Hard to say, but probably close to 50/50.

3) 20x Brock Lesnar (armed with steel baton) vs 1200kg black rhino: The power, durability, aggressiveness, and weaponry (long frontal horn) of the black rhino will be difficult for the Lesnars to contend with.  It will probably be unfazed by most of the baton blows, and will trample and gore its attackers with ease.  A "lucky strike" by one of the Brocks might give them a slight chance, but they will be outmatched on most occasions.  Black rhinoceros wins.

4) 40x Brock Lesnar (armed with steel baton) vs 5t Indian elephant: This will be similar to the last matchup, as the Indian elephant will be able to withstand most of the baton strikes and easily trample/gore its attackers.  As long as the elephant recognizes the Lesnars as a threat and reacts accordingly, it will win.  If it is caught off guard or is not mentally prepared to fight back, it may fall victim to the "lucky strike" mentioned earlier.  Edge to Indian elephant.

5) 8x Brock Lesnar (armed with steel baton) vs 200kg wild boar: Wild boars are aggressive, well-armed with tusks, and somewhat protected by tough hides.  A 200kg wild boar will be about a meter tall at the shoulder, and its head will be easily accessible for a baton strike.  The wild boar will be quick enough to slash & disable many of its attackers, but the chances of one of the Brocks landing a solid head shot is decent.  If one of the Brocks can stun the wild boar, the ones remaining will have an opportunity to finish it.  Edge to Brock Lesnars.

6) 15x Brock Lesnar (armed with steel baton) vs 1000kg caffer buffalo: Cape buffaloes (Syncerus caffer) are aggressive and unpredictable.  One can easily kill a human (and this species does many times each year).  Again, this will depend on the mentality of the parties involved.  A Cape buffalo violently fighting back and recognizing the Lesnars as a threat will have a good chance to win.  However, strike placement will be key.  If one Lesnar can get a solid hit on the buffalo's noggin, the Lesnars may have a chance.  However, it's a small chance.  The ease of movement of the Cape buffalo as it turns to wield it horns & hooves will make it dangerous for anything that comes close.  Could conceivably go either way, but overall I favor the Cape buffalo.

7) 8x Brock Lesnar (armed with steel baton) vs 200kg brown bear: The brown bear will be much stronger than the humans, but it won't be as quick as the lion, and won't have the lateral quickness to avoid a baton strike to the head if the Lesnars concentrate on this.  It will easily dispatch a few of the Lesnars as they attack, but may fall victim to an accumulation of head strikes.  Again, the mentality of each party is key.  A bear fighting fiercely and with focus will have the edge, a confused bear without focus probably won't.  If the Lesnars are determined to attack without regard to their own safety in order to accomplish the goal, they may have the edge.  Probably close to 50/50; slight edge to the 8 Brock Lesnars.

8) 20x Brock Lesnar (armed with steel baton) vs 600kg Utahraptor: A Utahraptor this heavy will likely stand well over 2 1/2 meters tall, which rivals the height of an ostrich.  The Utahraptor can quickly slash and bite to reduce the number of its attackers, and its agility will make it hard to contend with.  It's likely that several of the Brocks will be in range to whack the Utahraptor on the head as the battle ensues, and a few strong hits will likely slow the theropod down.  The carnage will be great, but 20 Brock Lesnars (if determined and unrelenting) should be able to pull this off more times than not.  Edge to 20 Brock Lesnars.

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.
