Interspecies Conflict/Fights


QUESTION: Let's use a 320kg Xeno for the following

Xeno vs smilidon populator
Xeno vs American lion
Xeno vs daedon
Xeno vs hyenadon
Xeno vs andrewsarchus
Xeno vs utahraptor

Helloid vs daedon
Helloid vs giant short faced bear
Helloid vs devil rat

Xeno vs devil rat

Daedon vs hippo

Xeno vs giant short faced bear

I know the bear was huge but Xeno is a 700lb cat with agility & 2500lb bite that no mammmilian predator can match & rivals a bite of an alligator

ANSWER: Hello Anthony.

Here's the recap:
XENO: ".... big cat, species Xeno , avg weight males 600lbs females 400lbs, live in groups of up to 12 it's always two males in each group, live on North American plains, top speed 45mph, 4inch canines, bluish-gray with jaguar pattern...."  More details on the super cat: 2500lb bite force...4inch claws...kills with a bite through the skull...excellent climber; most athletic cat.

HELLOID: "A tenacious, 250 kilogram mustelid. 4 inch canines, 4 inch claws. 1500 pound bite force. Excellent swimmer. Speed 80 km/h (running). Mainly terrestrial animal. Opportunistic ambush predator. Thick fur with random sharp bristles measuring 1 cm in length as defense. Jet-black in color, superb night-vision, both nocturnal and diurnal. Excellent sense of smell, able to smell a drop of blood 70 m away. Lives in packs of up to 50 in number, headed by an alpha male and an alpha female. Females and males equal in size.  Males experienced in combat, but still prefer ambush attack. Bristles can detect the slightest sound vibrations."

DEVIL RAT: "It is basically a 900 pound version of a normal rat. It has all of the smaller rat's physical characteristics (teeth, paws, etc), with proportionally larger red eyes, and a mouth that can open twice as wide."

320kg Xeno vs Smilidon populator: Smilodon will weigh at least 25% more.  Both cats are quick & powerful, but the Xeno's more enhanced weaponry & ability will help it close the gap created by Smilodon's weight advantage.  Once the 2 cats engage, the Smilodon will have greater control of the positioning (because of its size & strength edge), but Xeno's 4-inch claws will give it a boost in a swipe war.  Close fight.  Probably 50/50.

320kg Xeno vs American lion: The American lion was about 25% heavier than Xeno (and maybe more).  Like the Smilodon, the American lion would control the position battle against Xeno due to its size advantage, but it isn't quite as muscular or well-armed as the saber-tooth.  The American lion would probably need to have a 30% weight advantage against Xeno to give it an even fight, and it doesn't quite have that here.  Edge to Xeno.

320kg Xeno vs Daeodon: Daeodon will weigh over 3 times as much as Xeno.  Daeodon had powerful jaws & dangerous tusks, and would be nimble enough to keep from being flanked by Xeno on most occasions.  Xeno will need to be careful against an animal this big, but it isn't without hope.  If Xeno can dodge an initial charge by the pig well enough to latch onto its side, it can drive its canines into a vulnerable spot.  Xeno can win, but most of the time it will be overcome by the huge Daeodon's offense.  Daeodon wins.

320kg Xeno vs Hyaenodon: Hyaenodons had a wide size range, but the largest one (Hyaenodon gigas) weighed about 55% more than Xeno.  Hyaenodon's jaws were bone-crushing, but that was its only weapon.  Xeno's weaponry was more diversified, and it was more agile.  However, it would be in trouble with one good bite from Hyaenodon.  Could go either way, but I slightly favor Xeno.

320kg Xeno vs Andrewsarchus: Andrewsarchus' only remains are a section of its jaw, and its actual size is somewhat up in the air (a lot depends on how robust this animal was).  Once Andrewsarchus' size gets over 500kg, it will be a tough opponent for Xeno with its huge bite.  The highest reasonable estimates for this animal put its weight at 1000kg, which is over 3 times heavier than Xeno.  An Andrewsarchus this big would be too formidable for Xeno to overtake on most occasions, but Xeno's agility, weaponry, & killing technique would enable it to succeed against much larger animals on occasion.  Andrewsarchus wins.  

320kg Xeno vs Utahraptor: Utahraptor will weigh about 55% more than Xeno.  Utahraptor has deadly kick & a decent bite, but the agile Xeno will be able to close the distance & attach itself to the dinosaur fairly easily.  Xeno's ability to kill with a skull bite (with its enormous bite force) gives it a method of attack the Utahraptor will have a hard time defending.  Close fight, but Xeno has the edge.

Helloid vs Daeodon: Daeodon will weigh 4 times as much as Helloid.  Helloid is a powerful combatant with its toughness & weaponry, but it will have a hard time dealing with this huge, charging animal with a big bite & sharp tusks.  Helloid can't be counted out because it has dangerous teeth & claws (and a potent bite-force), but it's giving up a lot of size here.  Daeodon wins.

Helloid vs Giant short-faced bear: The short-faced bear will weigh 4 times more than Helloid.  Helloid has ferocity, sharp claws, & sharp teeth (and a powerful bite force).  However, it will have a hard time dealing with the forelimbs of the much larger bear.  The short-faced bear will easily control the positioning of the fight, and its great strength will allow it to lessen the Helloid's ability to swipe effectively with its claws.  Helloid's bite can cause damage, but the thick coat of the bear will protect it long enough to seize control & land some bites of its own.  Giant short-faced bear wins.

Helloid vs Devil rat: The Devil rat will weigh over 60% more than Helloid.  Devil rats have rotund bodies that make effective bites somewhat problematic to land (because the gape will need to be wide), but its tapered head & pointed snout can be targeted by an attacker.  The Devil rate has a wide bite & sharp incisors that can cause deep wounds, but it has no other offensive weaponry.  Helloid is a fighting machine, armed with long, sharp claws that can slice into an opponent multiple times to wear it down.  The bristles on Helloid's tough hide will help to deflect many of the huge rat's bites, and the mustelid can clamp onto the snout or skull of the rodent & use its great bite force to cause great damage to this unprotected area.  Not an easy fight, but Helloid has too much going for it.  Helloid wins.

320kg Xeno vs Devil rat: Xeno will be about 78% of the Devil rat's weight.  The Devil rat will have a size advantage & enough mobility to ensure it will land some bites, but Xeno will be quick enough to leap upon it and sink its claws into its hide.  Xeno can pierce the vulnerable skull of the Devil rat with its long canines, and should be able to do this before it takes too many bites from the rodent.  Xeno wins.

Daeodon vs Hippo:  Daeodon (formerly known as Dinohyus), was the size of a bison and had a large head with crunching jaws and dangerous canine teeth (tusks).  The healthy male hippopotamus can weigh over 2 tons (older ones exceed 3 tons) and has jaws (featuring huge lower canines and forward-pointing lower incisors) that can open 4 ft wide.  The hippopotamus is capable of short bursts of speed on land, but its small legs (in proportion to its rotund body) make sustained mobility a challenge compared to animals that are entirely land-based.  The hippo is at home in the river where the water can help support its great weight.  The Daeodon will try to use its better mobility to bite and tusk the hippo, and will probably succeed in causing injury to the larger hippo.  However, the hippo will try to bite Daeodon with its massive jaws (the tusks could seriously wound the Daeodon) and drive the incisors into its body.  The Daeodon would probably inflict more injuries to the hippo than the other way around, but the hippo's less-frequent offense would be more substantial.  The Daeodon would be able to avoid the jaws of the hippo at the onset, but chances are it will get caught at some point.  The Daeodon can win this if it's careful, but more times than not the hippopotamus will prevail.

320kg Xeno vs Giant short-faced bear: The short-faced bear will weigh over 3 times as much as Xeno.  Xeno will try to circle the bear (to avoid the paw swipes) and leap upon it with the intent of sinking its long canines into a vulnerable spot (neck or skull).  However, bears have decent mobility, good durability, & great endurance.  The short-faced bear will have the flexibility to counter-attack when Xeno latches on, and the ursid will easily control any positioning if it remains facing the felid.  Xeno would actually have a tough fight with a bear half this size, and one this big will be too strong & capable to bet against.  Giant short-faced bear wins.

Best regards.

QUESTION: Giant short faced bear vs daedon
3 Xenos(320kg) vs daedon
3 Xenos(320kg) vs giant short faced bear
3 Xenos(320kg) vs andrewsarchus
3 Xenos(320kg) vs hippo

ANSWER: Hello again Anthony.

Giant short-faced bear vs Daeodon: Daeodon was similar in weight to the giant short-faced bear (Arctodus simus).  Daeodon had dimensions similar to a wood bison, but had a head that looked somewhat like a warthog's.  It also had a strong bite capable of causing damage in a conflict.  The short-faced bear was not as robustly built as today's brown bears, and would have had some difficulty controlling the head of Daeodon well enough to keep itself from being tusked.  If the South American version of this bear (Arctotherium) is used, it would have a 60% weight advantage over the pig, and would easily prevail.  Arctodus simus wasn't as accustomed to tackling large prey as some of today's bears (grizzly, polar, etc.), and wouldn't fare as well in a parity fight with Daeodon.  Close fight; slight edge to Daeodon.

3 Xenos(320kg) vs Daeodon: Daeodon will weigh slightly more than all 3 Xenos combined.  For a weight comparison, imagine 3 leopards taking on a giant forest hog.  The Xenos will need to be cautious & cooperative to prevail in this battle with the dangerous Daeodon.  The 4-inch canines of the Xenos (driven with a 2,500lb bite-force) should be able to penetrate Daeodon's hide without much problem, and the athleticism of the felids should enable them to avoid the jaws & tusks of the giant pig.  Daeodon can win if it takes one Xeno out early, but the 3 cats should be nimble enough to latch onto the flanks of the entelodont & bring their finishing experience into play.  Edge to the 3 Xenos.

3 Xenos(320kg) vs Giant short-faced bear: The giant short-faced bear (Arctodus simus) will weigh slightly more than all 3 Xenos combined.  For a weight comparison, imagine 3 jaguars taking on a grizzly bear.  The bear will have the endurance to turn & swipe vigorously throughout most of the fight, but it will have difficulty making meaningful contact with the agile Xenos.  The Xenos will need to attack from different sides to keep the bear from concentrating on just one of them.  The Xenos will need to eventually leap upon the bear to make a finishing attempt, but this will put them in range of the bear's offense (bites & swipes).  A strong, solid hit by the bear can disable a Xeno, and if that occurs early on, the odds will swing into the ursid's favor.  Teamwork & weaponry are great assets for the Xenos, but this is a big bear.   Interestingly enough, even though I favored Daeodon to edge the giant short-faced bear in their on-on-one battle, the bear would actually fare better against the Xenos than the pig would due to its use of paws.  If we use the South American giant short-faced bear (Arctotherium), it will weigh as much as 5 Xenos.  For that scenario, imagine 3 jaguars taking on a Kodiak or polar bear.  The 3 Xenos would be outmatched by the size & power of the huge Arctotherium.  However, using the Arctodus simus, it would be a fair fight.  Close to 50/50; slightest of edges to the 3 Xenos.

3 Xenos(320kg) vs Andrewsarchus: Andrewsarchus, at the reasonable upper-estimates for its weight, will weigh slightly more than all 3 Xenos combined.  Andrewsarchus had long jaws filled with bone-crushing teeth, and this would be what the Xenos would need to avoid.  Despite the Xeno's agility, it would be hard to do this throughout the duration of the battle.  The hide of Andrewsarchus was probably not as tough as Daeodon's, and the fangs of the 3 cats would easily breach it.  It would be important for the Xenos to latch onto Andrewsarchus in a good-enough position (like the back, neck, or sides) to be reasonably safe from a counter-attack.  Andrewsarchus would probably succeed in landing a disabling bite to one Xeno some of the time (to gain the advantage of facing only 2 Xenos), but the nimble cats would probably leap onto the larger animal & land good finishing bites more times than not.  Edge to the 3 Xenos.

3 Xenos(320kg) vs Hippo: A big river hippopotamus can weigh over 8 times more than a single Xeno, but it will have its work cut out for it here.  Hippos have huge jaws with dangerous teeth (especially the lower canines), but they are ill-suited for extensive activity (including fighting) when they must do so on land.  Although they are capable of short bursts of speed on land, their massive bodies move better in the water because the water helps to support their weight.  If the Xenos are alert, they can avoid the charges & chomps from the hippo, and move into position to leap upon it.  Once the Xenos sink their 4-inch claws into the hide of the hippo (which is thick but certainly not impenetrable), it will be difficult for the hippo to shake them off.  The Xenos can claw & bite away without reasonable fear from a counter-attack, and eventually cause enough serious wounds to overcome the hippo.  Hippos are extremely dangerous in their element (shallow water), but they aren't equipped to effectively deal with 3 Xenos on land.  A hippo might earn a 50/50 in shallow water (considering the Xenos won't feel comfortable fighting there), but on land it will be in trouble.  3 Xenos win.

Best regards.

QUESTION: 7 Xenos (320kg) vs South American short faced bear
7helloids vs South American short faced bear
Kodak bear vs short faced bear
Allosaurus vs giant short faced bear
Andrewsarchus vs giant shortfaced bear
15 Xenos vs African elephant
Big Show 7ft (500lbs) vs gray wolf

Hello Anthony.

7 Xenos (320kg) vs South American short-faced bear: The South American giant short-faced bear (Arctotherium) will weigh as much as 5 Xenos.  The key to the Xenos' success will be the 4" claws (to grip & shred with), the 4" canines (to enable a quick killing bite to be delivered in various locations), & their agility (to enable them to avoid a lot of the bear's offense).  The Arctotherium will have the power to seriously injure the Xenos, and the endurance to battle for an extended period of time.  The Xenos have the ability to pull this off, but it is imperative they work as a team.  If they all avoid injury & latch onto the bear (which will impede its movement), they can land multiple bites & slowly wear the giant ursid down.  The Arctotherium will be able to reduce the numbers with its attack on some occasions, and the Xenos will need all 7 members in order to prevail here.  Probably a 50/50.

7 Helloids vs South American short-faced bear: The bear will weigh almost as much as all 7 Helloids combined.  The ferocious Helloids have sharp claws & teeth, but they won't have the same level of agility as the Xenos will, and will find it harder to avoid getting struck by Arctotherium's paws.  A good swipe from the giant bear's paw can disable a Helloid (dispite its durability) due to the bear's great power.  The Helloids can't leap as well as the Xenos, and will need to "climb" upon the Arctotherium to maintain a hold on it.  It's going to be a challenge for the mustelids to advance upon the South American giant short-faced bear without having their numbers reduced by the bear's counter-attacks.  Even though the Helloids are capable of victory here, it won't happen on most occasions.  South American short-faced bear wins.

Kodiak bear vs Short-faced bear: The Kodiak bear will weigh about 2/3rd the short-faced bear's weight.  Although the Kodiak is more robustly built & probably better suited for combat, it's giving up too much weight here.  A parity battle would favor the Kodiak, but at these weights the Kodiak will get overpowered.  Short-faced bear wins.

Allosaurus vs Giant short-faced bear: Allosaurus weighed almost twice as much as Arctodus simus, and almost 15% more than Arctotherium.  Arctodus simus would be too small to effectively grapple with Allosaurus or make much headway with paw swipes.  Allosaurus would cause a lot of damage to the bear with a single bite of its huge jaws, and the bear would not have the mobility to avoid this.  Arctotherium, on the other hand, would have had the power to grapple with Allosaurus (and perhaps topple it on occasion), and its paw swipes would have been powerful enough to have some effect.  However, Arctotherium did not possess the mobility to avoid getting bit by Allosaurus' jaws.  Allosaurus would win against Arctodus simus, and would have the edge against Arctotherium.

Andrewsarchus vs Giant short-faced bear: If the reasonable upper-estimation is used for Andrewsarchus, it weighs about the same as Arctodus simus.  Arctotherium was about 60% heavier than Andrewsarchus, and would easily prevail in a battle with it.  The short-faced bear wasn't as robust as today's bears (built more for running), and wouldn't have been as adept at tackling similar-sized opponents as, let's say, the polar bear or the Kodiak bear.  Its ability to use its forearms to swipe at/control adversaries was still good enough to aid it in this matchup, but the large, powerful jaws of the equally large Andrewsarchus would have been problematic.  It would have been difficult for the short-faced bear to mount a steady offense (with paw swipes & bites) and avoid the jaws of the Andrewsarchus at the same time.  In many ways this reminds me of spotted hyena vs sun bear (which is close).  This is close to 50/50.

15 Xenos vs African elephant: The elephant will weigh almost 22 times more than a single Xeno and will be 3 times taller at the shoulder.  However, the Xenos have the numbers & weaponry to win.  Because the Xenos' claws are 4" long, they can grip onto the elephant's hide while bites are delivered.  Once the Xenos swarm it, the elephant will have a difficult time getting them off.  The elephant's use of its great weight (to crush), its trunk (to swat or pull), and its tusks (to stab) may be effective in isolated incidents throughout the battle, but the agile Xenos will be able to get the positions they want if they're careful.  It will take the Xenos a long time to wear the huge pachyderm down (with blood loss & fatigue), and they won't prevail every time, but this many big cats should be enough to come out on top most of the time.  Edge to the 15 Xenos.

Big Show 7ft (500lbs) vs Gray wolf: The Big Show (Paul Randall Wight Jr.) will weigh well over 3 times more than a gray wolf.  The outcome of this battle would depend heavily on the mental toughness of Big Show.  He demonstrates this as an entertainer, but whether or not that translates to real life is key.  Big Show has the physical tools to subdue the wolf, but to apply whatever combat skills he has into effective techniques (strikes/chokes/etc.) while getting bit (which will definitely happen) will depend on his mental toughness.  Big Show is in above-average physical shape for sure, but that doesn't always guarantee a great combatant in a real-life situation.  The wolf will have greater endurance, but its jaws are its only real weapon.  This would be a lot like an average-sized man taking on a coyote.  It's hard to answer this accurately without knowing Big Show's mental makeup, but I would guess he has enough toughness to battle through injury & drive the wolf away on many occasions.  A wolf can certainly kill a man this big if it is determined to do so, so it can't be counted out.  Maybe close to a 50/50; just depends on factors I can only guess about at this point.  

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.
