Embolotherium (5.5m length 3m height 6t weight) vs 7t African elephant: Embolotherium was a brontothere, and its build is presumed to be similar to Brontotherium (Megacerops). However, instead of the "Y" shaped horn of Megacerops, Embolotherium had a flat, spade-like projection protruding vertically from its snout area. This "horn" was believed to be rather fragile compared to the Megacerops' horn, and likely wasn't suited for battling other males. The African elephant is an extremely strong animal with sharp tusks, and a full-grown one is virtually immune from predation. If the Embolotherium's nose projection was as useful as a weapon as a Megacerops' horn or a rhino's horn, I would give it a solid chance to compete with the African elephant in a battle (I favor a rhino over an elephant at close weights due to the rhino's horn being a more effectively-positioned weapon than the elephant's tusks). However, due to the state of the Embolotherium's "horn", it won't be favored against the heavier elephant. Edge to African elephant.
Embolotherium (5.5m length 3m height 6t weight) vs lion pack (6x 250kg lion + 14x 150kg lioness): A lion pride is a very effective hunting group, and can bring down animals of impressive size & weight (buffalo, giraffes, etc.). Lions have great agility and athleticism, and these attributes will enable them to move evasively as the Embolotherium attempts to defend itself. However, in the same way a 6-ton elephant would be almost impossible for a pride of lions to overpower due to its great size and strength, the Embolotherium would be a very tough challenge for the cats. Overcoming the Embolotherium with biting and clawing will be difficult as the huge animal is actively resisting, and the lions could get trampled or injured by the impact of the brontothere's head. If the lions attack without regard to the overall safety of the pride (which won't be a realistic action), they have the numbers to eventually succeed. Realistically, the lions will back away once the Embolotherium begins angrily charging at them. Close to 50/50; depends on how you look at it.
Embolotherium (5.5m length 3m height 6t weight) vs 7t Acrocanthosaurus: Acrocanthosaurus was a large theropod dinosaur that may have hunted in packs. Its large jaws were armed with 68 serrated teeth that aided it in hunting and killing. One of the prey items Acrocanthosaurus feasted upon was Sauroposeidon, a sauropod reaching 40 tons in weight. Embolotherium's nose projection would not have been as effective against Acrocanthosaurus as the weaponry of Elasmotherium or a ceratopsian, and it wouldn't be able to injure the theropod or drive it away as easily. It's more likely Embolotherium would succumb to bites in an altercation with this dangerous hunter. Edge to Acrocanthosaurus.
Embolotherium (5.5m length 3m height 6t weight) vs 5t Megatherium: Megatherium was a giant ground sloth. It was a rather slow mover, but was armed with powerful forelimbs armed with huge claws. Megatherium could stand upright close to the height of a giraffe, and was covered in tiny osteoderms under its furry hide (this protected it from many attacks). This battle would depend on how effective the charges of Embolotherium would be against Megatherium (which would not be quick enough to get out of the way) and how effective the claw swipes of Megatherium would be against Embolotherium. The impact of Embolotherium's charges might cause injury due to concussive force, but would not be a real threat to breach the giant sloth's hide in any way. I don't see how the Embolotherium could mount an offense without putting its relatively fragile nose "horn" in danger of being damaged, so I'm sure how eager it would be in proceeding in this particular battle. It would likely be able to knock the Megatherium back if it attacked without regard to this, but might be repelled by the Megatherium's claws if it was tentative or passive. These animals would likely coexist peacefully, but any battle with willing participants would likely be a toss-up at the given weights (and the Megatherium might yield to the larger animal if any hostilities arose). Close to 50/50; slight edge to the larger Embolotherium.
650kg female Sumatran rhino vs 20x Brock Lesnar (no weapons, hard clothing, work together): The Sumatran rhino will weigh almost 5.5 times as much as Brock Lesnar. Sumatran rhinos are the smallest rhinos that exist today. They have powerful bodies and 2 horns on their noses, but the longer one in front typically doesn't exceed the length of a banana in the males (and are even smaller on the females). Brock Lesnar is a strong human being with great physical prowess and fighting skill (wrestled, played football, became an MMA champion). Although the rhino might try to flee from 20 attacking Brock Lesnars, it will be a very tough adversary if it stands its ground. The Brocks won't have an effective way to injure the rhinoceros (punches and kicks will have minimal effect), and the rhino will be able to easily injure the attacking men (its horn can be used to break bones in a human upon impact, and its bite can cause damage as well). Predatory wild animals that attack prey have specific tools and techniques to make a kill whether solo or in a group, but an unarmed human does not really have that type of ability. Edge to Sumatran rhino.
300kg American black bear vs 20x Brock Lesnar (no weapons, hard clothing, work together): The American black bear will weigh 2.5 times as much as Brock Lesnar. The American black bear is an excellent tree climber, and has very sharp claws to aid it in this activity. Bears are very strong, durable, and have great endurance. A black bear's claws and jaws could easily cause serious injuries to a human, even one as large and strong as Brock Lesnar. If 20 Brocks attacked a black bear collectively, the bear would likely flee (like the Sumatran rhino would), but could easily incapacitate many of them very quickly if it stood its ground. The Brocks would not have an easy way to injure the black bear, but an accumulation of kicks and punches might take their toll if the right areas were targeted. The bear's much greater strength and superior weaponry can't be ignored, and it would probably make the remaining Brocks back off once it injured the first few in a small amount of time. There won't be enough room for all 20 Brock Lesnars to put hands on the bear at the same time, and the bear will quickly disable the ones closest to it. Imagine, for comparison, 20 regular humans weighing 105lbs each trying to subdue Brock Lesnar.....I think they'd have great difficulty. The Brocks might have a decent chance (to restrain the bear) if they focus on the goal without regards to the safety of the group, but that won't realistically happen. I certainly give the humans a good chance (because there are so many of them), but I can't confidently go against the black bear here in a realistic scenario. Depends on how you look at it.
350kg zebra vs 140kg lioness: This is a common predator/prey relationship, but the zebra is a very difficult quarry on many occasions. Zebras can kick strongly with their back hooves, and will bite as well. A lioness will need to be wary of the equid's kicks, but should have the agility, quickness, and athleticism to stay out of harm's way if she's careful. The zebra won't have as effective a way to keep the lioness from leaping to its neck in a frontal attack as it will from a lioness attacking its rump, and the zebra will have trouble utilizing its weaponry once the lioness clings to it. A lioness is well-practiced at dispatching this particular prey item, and should succeed in a serious battle more times than not at these weights. Edge to lioness.
350kg zebra vs 2x 80kg hyena: Hyenas (we'll use the spotted) are excellent group hunters, but a zebra will be a tough challenge (even though these hyenas are huge at 80kg). Because the zebra can spin and kick quickly with its powerful rear hooves, it will be hard for the hyenas to safely venture in to land a bite. The zebra will probably be able to defend itself better from the hyenas than an equally-sized bovid would because of this. Hyenas are extremely durable and have very high bite forces, so they are equipped to pull this off. A hyena can single-handedly overpower large prey items on occasion, and 2 hyenas can divide the focus of any quarry. A hyena isn't as agile or quick as a big cat will be, and each one might not be able to avoid getting kicked after closing in. The zebra will be able to drive the hyenas away some of the time, but others times it will fail to do so and be overpowered. Add a 3rd hyena and it's a done deal. Close to 50/50.
350kg zebra vs 10x 20kg dhole: The dhole (Asiatic wild dog) is an excellent pack hunter with a strong bite and very good lateral quickness. A kick from a zebra can easily kill a dhole, but 10 of them will make it hard for the zebra to target a single one with precision. The dholes will quickly dart in and out to land bites, and will use their solid endurance and persistence to eventually wear the zebra down. Once it tires, the dholes will have a chance to land more damaging bites and perhaps pull the fatigued equid to the ground. The zebra will drive the dholes away on occasion, but a determined attack will be difficult to defend against. From a size perspective, this will be like 10 grey wolves taking on an American bison (which 10 wolves are capable of doing). Edge to 10 dholes.
150kg green anakonda vs 8kg king cobra (land): Green anacondas kill by constriction, but one could easily bite and swallow a king cobra if it were inclined to do so (green anacondas sometimes eat smaller green anacondas, so one might possibly take such action). However, the most important factor of this fight is how the king cobra's venom will affect the anaconda. A king cobra can inject a great deal of venom with one bite (the 2nd largest potential venom yield after the gaboon viper), and this bite is capable of killing an elephant. Because the anaconda is cold-blooded, the cobra's venom might not effect it to nearly the same degree (or speed) as it would affect a warm-blooded animal. Some snakes are immune to the venom of other snakes, but I'm not quite sure if that's the case here (they reside on different continents). Either way, the anaconda can easily kill the king cobra if it wants to. The result of this battle will be that the anaconda kills the cobra and suffers no ill effects from any bite it receives, the anaconda kills the cobra and suffers some effects to some degree (up to and including death), or the king cobra gets a quick initial bite in that affects the anaconda profoundly enough to keep it from effectively retaliating. King cobras sometimes kill and eat small pythons, so its venom may affect the anaconda. If so, the venom may take a while to take effect, and the anaconda will have some time to dispatch the smaller snake. Not a mismatch despite the size difference, but edge to green anaconda.
1200kg Titanoboa vs 3x 8kg king cobra (land): Titanoboa was a huge constrictor that was over twice as long as a green anaconda and many times as heavy. As with the anaconda vs king cobra matchup, Titanoboa will probably be able to kill the king cobras with relative ease if it wants to, but it's fate after the battle is over will depend on how the cobra venom affects it. 3 king cobras will easily have enough venom to dispatch virtually any warm-blooded animal weighing 1200kg, but with Titanoboa it's not a certainty. Overall edge to Titanoboa.
150kg green anakonda vs 65kg Rotwailer (land): Green anacondas aren't as effective in combat on land as they are in the water because of their poor mobility and limited stamina. They don't typically do well against large, mobile opponents on land. However, they can strike quickly to grip onto an adversary and position their coils for constriction, and this is hard to defend against. A green anaconda can easily asphyxiate an animal larger than itself. The Rottweiler is solid, muscular dog with a broad head. It has been used by the police and the military. The Rottweiler will have huge advantages in mobility and endurance in this battle, but it will not know how to attack the green anaconda with the precision required to keep it from exposing itself to a dangerous position. The Rottweiler will rush in to attack with its jaws (likely a clamp and shake), and won't be wary of the anaconda's advancing coils. If the anaconda wraps around the Rottweiler a couple of times, the dog will have no way to free itself. Both animals will initially have their jaws locked on one another, but the anaconda will be in better shape to overpower the dog than the other way around. If a Rottweiler was trained specifically to attack anacondas and knew exactly where to target (like a jaguar can do) or nip and retreat until the snake was exhausted, the dog might have a fair chance to dispatch the snake. Without any special training, the Rottweiler won't really know what it would be getting itself into. Edge to green anaconda.
150kg green anakonda vs Brock Lesnar (land, no weapons, hard clothing): The green anaconda will weigh about 25% more than Brock Lesnar. Lesnar will need to know something about the anaconda's physiology to have a chance here. He will need to target the relatively fragile skull and head area of the snake to overcome it, and his strength and striking power will give him the tools to do this. The anaconda will be much stronger than Lesnar, and will likely strike quickly to latch onto him at the onset of the battle. The backward-pointing teeth of the anaconda will make it very difficult to remove, and Lesnar will have a short amount of time to attack the vulnerable areas (head and spine) before the coils of the snake enable it to advance to a dominant position. Even Lesnar won't have the strength to remove the green anaconda's coils once they wrap around him, and he will be doomed. If he can somehow avoid the initial strikes of the anaconda and wait until the reptile tires from its attempts to do so, Lesnar will have a better chance to attack effectively while the snake is less than 100%. The mind of Lesnar will be his biggest asset (he can strategically decide how to proceed), but he will have an uphill battle once physical contact is made. Edge to green anaconda.
