We have to review the real world versus fights on which ones to keep and which ones to remove too, because it's not as simple as "stronger = stomp" as the real world is more nuanced than that.
Komodo Dragon vs Pit Bull (dragon won): I removed this fight because it feels like a stomp to me. The dragon is much larger, stronger, and has venom. I don't see under what conditions can the pit bull harm the dragon at all.
African Wild Dog vs Wolf (wolf won): Wolves are larger than African Wild Dogs, however the strength gap is small enough for it not to be a stomp. African Wild Dogs are indeed capable of taking down prey far larger than itself, but a wolf is a carnivore capable of defending itself as well. I'm not sure how the wild dog will be able to compete with the wolf though since they seem to be similar animals but the latter has all the advantages. Not a stomp, but I'm not sure if this is a fair fight.
Komodo Dragon vs Wolf (wolf won): I think this one is fine to keep. The thread acknowledged the dragon's superior strength, but wolves can win this fight through their superior skill/speed and can kill the dragon by a quick bite to the neck. The dragon's wincons would probably be to land a heavy hit with its tail or bite it with venom.
Wolf vs Chimpanzee (wolf won): I think this is fine. They have both been downgraded to 10-A and strong men have fought wolves to varying results in real life.
Tiger vs Lion (tiger won): Happened in real life, definitely fine.
Tiger vs Grizzly Bear (bear won): Same.
Leopard vs Jaguar (jaguar won): Shouldn't be a stomp, but jaguars are pretty clearly stronger.
4 Chimps vs 1 Gorilla (chimps won): Pretty interesting matchup, probably fine.
Bull vs Draft Horse (bull won): As said in the thread, a good ram by the bull will probably kill the horse as they can kill tigers and bears. Horse has a bit better manoeuvrability and can harm the bull with its kicks, so I guess it's not a stomp.
Cow vs Central European Boar (boar won): Cow's advantages are superior strength and accuracy, boar's advantages are agility and piercing damage, I think it's a good fight.
White Rhinoceras vs American Bison (rhino won): Rhino is larger and has a sharp horn. Might not be a stomp, but I'm not sure how the bison would even harm the rhino? A smaller rhino would probably be a fairer fight with the bison.
Grizzly Bear vs Hippopotamus (hippo won): I don't think the bear stands a chance at all against the hippo. Might be a stomp.
Grizzly Bear vs Polar Bear (polar bear won): Fine
Elephant vs Rhinoceras (elephant won): Happens in real life and the elephant is definitely the one with the advantage, but the rhino has wincons via being faster and having a sharp horn so I think it's fine to keep.
