Hi BK! Long time no see.
Anyways, I know a breed of Aseel fighting gamefowl by the name of Sindhi Aseel, the largest variety of Aseel gamefowl. It can tower up to an impressive 30 32 inches in height!
So let's go,
1. Sindhi Aseel vs Caracal
2. Savannah F1 vs German Shepherd
3. Hippopotamus vs Grizzly Bear
5. Short faced bear vs Modern Hippopotamus
6. Marshall eagle vs Golden eagle
7. Indian mongoose vs least weasle
8. False gharial vs Bull Shark
9. Pit bull vs Iberian Lynx
10. Main event: Sindhi Aseel gamefowl vs Golden eagle
1. Sindhi Aseel vs Caracal: A caracal can weigh as much as 3 Sindhi Aseel gamefowls. Aseel gamefowls can cause injury with their kicks (kind of like a mini-cassowary), but a caracal will be too formidable for the bird. Caracals are quick & agile, and can overpower prey items much larger than an Aseel gamefowl. The caracal will pounce upon the gamefowl, and will use its claws & teeth to dispatch the bird. The Aseel gamefowl won't be able to prevent the caracal from overtaking it. The caracal is an athletic cat with great leaping ability, and will move too explosively for the Sindhi Aseel gamefowl to react to. Caracal wins.
2. Savannah F1 vs German Shepherd: A savannah cat (cross between a serval & a domestic cat) can weigh about 1/3 the weight of a German Shepherd. Savannah cats are extremely quick, agile, & are great leapers. German Shepherds are intelligent & trainable, and are commonly used by the military & the police. The savannah cat has sharp claws & teeth, but will have a great deal of trouble stopping the big bite of an attacking German shepherd. Dogs typically have much greater stamina than cats, but the battle won't last long enough for that to become a factor. The German Shepherd is simply too big. German Shepherd wins.
3. Hippopotamus vs Grizzly Bear: The hippopotamus will weigh 4-6 times more than a grizzly bear. Hippos have huge jaws armed with sharp-edged canines (and forward-pointing incisors), and can be very aggressive & territorial at the water's edge. Hippos aren't as formidable out on land as they are by the river, but can still be dangerous adversaries due to their large size & weaponry. Grizzly bears are strong, muscular mammals with great durability & endurance. They have strong bites & long claws, and can use their forelimbs to manipulate & control opponents in a fight. A grizzly bear can potentially injure a hippopotamus, but it's not large enough to compete with it effectively on most occasions. The grizzly bear doesn't have enough lateral movement to avoid getting chomped by the hippo's jaws (which can cause devastating injuries), and won't be able to dish out enough offense to overpower the larger animal before this occurs. A grizzly bear might be able to deter an uninterested hippo with a few paw swipes if they're away from the water's edge, but won't have enough ammunition to stop one determined to attack. The hippo is simply too big. Hippopotamus wins.
5. Short-faced bear vs Modern Hippopotamus: There are 2 main types of short-faced bears. Arctodus (North American short-faced bear) was believed to have weighed about 1000kg, and Arctotherium (South American short-faced bear) was believed to have weighed almost 1600kg. Arctodus would have a better chance against a hippopotamus than a grizzly bear would, but will still run into the same problems when encountering one (not mobile enough to avoid the hippo's bite/can't dish out enough damage with its paws & claws before it receives a serious bite). The hippo will weigh anywhere from almost twice as much as Arctodus to almost 3 times as much, and will simply be too big on most occasions. Here is an earlier answer to the Arctotherium vs hippo matchup: The hippopotamus will weigh about 70% more than the South American short-faced bear (Arctotherium), but will only reach about 3/4th its shoulder height. Hippopotamuses have large jaws with imposing canines, and these sharp-edged teeth can cause serious wounds to any opponent. Hippos can be very aggressive & territorial in or near water, but aren't as comfortable when completely on land. Although they are capable of quick bursts of speed on land, they don't have the greatest mobility or stamina there. Arctotherium is believed to be the largest bear ever, and may have been closely related to the sloth bear. All bears have great endurance & durability, and Arctotherium was likely capable of causing a lot of damage with its jaws & swinging paws. The hippo would likely have been able to land its bite on Arctotherium throughout the fight (bears don't have the best lateral movement; especially large ones), but it would take more than one to take out the giant bear. The hippopotamus would be too strong to hold in place initially, but Arctotherium would have some success with its paw swipes until the hippo fatigued. This battle depends a lot on the bear's ability to avoid receiving a serious bite while mounting an effective offense with its jaws & claws. I would favor a hippopotamus at the water's edge, but the Arctotherium would have the edge on dry land. Close to 50/50. So the hippo wins against Arctodus, but gives an even fight to Arctotherium.
6. Martial eagle vs Golden eagle: These birds will weigh about the same. The martial eagle is the largest eagle in Africa, and is the aerial terror of the savannahs. It can take large prey (even servals & jackals need to be wary), and has very strong talons (can break a man's wrist). The golden eagle is an aggressive, sometimes combative bird that also takes reasonably large prey & has strong talons. It commonly battles other bird-of-prey species, and steals food from them on occasion (and is a formidable presence at a carcass). Both of these birds have similar attributes, and a battle between them would be quite close. Slight edge to the martial eagle.
7. Indian mongoose vs Least weasel: The Indian mongoose can weigh up to 7 times as much as a least weasel. The least weasel can tackle prey much larger than itself (and kills with a bite to the back of the skull), but these prey items aren't as formidable as an Indian mongoose. Indian mongooses are quick & agile, and sometimes overpower cobras by dodging their strikes & seizing them by the back of the neck with their jaws. These animals have relatively similar attributes & abilities, but the mongoose is simply too big. Indian mongoose wins.
8. False gharial vs Bull Shark: These animals can be similar in weight, but the physiology of each animal is a more important factor with this particular matchup. Gharials have slender snouts & small, sharp teeth designed to capture fish. They don't have the same means as, let's say, a Nile crocodile to injure another large animal. The false gharials jaws are much weaker than a crocodile's, and aren't suitable for grabbing & holding large, struggling prey. The bull shark has a strong bite with razor-sharp teeth, and will have an overall maneuverability advantage over the gharial. The gharial won't have an effective means to injure the bull shark, but the bull shark can injure the gharial (on the less-armored areas of its body) with its bite. Bull shark wins.
9. Pit bull vs Iberian Lynx: The American pit bull terrier will weigh twice as much as the Iberian lynx. APBTs are among the best canine combatants, and have great strength, athleticism, durability, & endurance. A game-bred & experienced one is an aggressive & relentless foe. Iberian lynxes are quick, agile, & well-armed (jaws & claws), but one will have trouble dealing with the style of attack the larger canid will employ. The ABPT will likely rush in immediately & latch onto the lynx (head & face area), and use its muscular body to violently shake its head to initiate damage to the felid. The lynx can inflict wounds with its claws (especially its kicking back claws), but it won't have enough effect on the APBT before it succumbs to the dog's offense. A large Iberian lynx would have a decent chance to repel a regular pet APBT with a strong defense, but will still have problems winning a serious battle. Pit bull wins.
10. Main event: Sindhi Aseel gamefowl vs Golden eagle: These birds will weigh about the same. The maneuverability of the golden eagle in flight will give it a definite advantage over the more terrestrial gamefowl, and it should be able to win if it attacks from the air (even if the gamefowl sees it coming). The strong talons of the golden eagle can easily dispatch the Sindhi Aseel gamefowl. If the golden eagle approached the gamefowl by walking toward it (which would not be normal behavior for the eagle), it would run the risk of being kicked, and would probably lose the encounter (unless it got close enough to get a grip with its powerful talons). The Sindhi Aseel gamefowl can be a handful for a similar-sized animal that approaches along the ground, but the aerial attack of the golden eagle will be too much. Golden eagle wins.
