User blog comment:Monkey Doctor 33/MD 33's Third Battle: Indominus rex vs Vastatosaurus rex/@comment-4661256-20150702000735

El Alamein's Edges:

 Strength:  In this category, I'm inclined to give the edge to the V. Rex. While the I. Rex's feats were fairly impressive, including basically beating a T. Rex and several velociraptors in a sustained fight, they pale in comparison to the V. Rex, who deals with deadly encounters on a daily basis and must utilize its natural abilities to kill for food (and therefore, survive). The I. Rex was always fed by its handlers at Jurassic World. Not only that, but the V. Rex is taller and heavier, making it that much more of a presence to be aware of whenever it decides to take a bite out of the opposition.

Edge: Vastatosaurus Rex

 Endurance / Durability:  An interesting thing to note, if you pay special attention to the design of the V. Rex, is that it's covered in scars along its rough hide. This implies that there has been many a prospective meal that was daring enough to attempt to defend itself. It also implies that the V. Rex has survived all of these attacks. By sheer virtue of having scoured the grounds of Skull Island for a long period of time prior to the arrival of Carl Denham's film crew, we can reasonably assume that the V. Rex has a lot more experience fighting capable opponents than does the I. Rex. It might seem like this analysis belongs more in the Experience category (and perhaps it does), but this idea helps support my claim that, by having fought longer and against more combat-capable opponents, the V. Rex will be able to take more hits and keep going longer in the fight than its opponent, whose rampage across Jurassic World ended as soon as it encountered a foe who fought back.

Edge: Vastatosaurus Rex

 Speed:  Both predators have similar abilities as far as maintaining an impressive stamina are concerned, but the I. Rex is still slightly faster than the V. Rex (30 mph vs. 27 mph). This means that if one dinosaur is pursuing the other at a critical point in the battle, the I. Rex will have that little extra bonus that will give it quite an advantage. On a side note, where did you unearth statistics detailing the speed of the two dinosaurs? I'm curious.

Edge: Vastatosaurus Rex

 Jaw Strength / Teeth:  Both of these two dinosaurs are going to be packing some serious metaphorical lead with their formidable jaws and sharp, serrated teeth. Even if one dinosaur has a slightly higher bite force, in my mind, the differences are negligible. Both of them rely heavily on their jaws as their primary weapons, and both of them will deliver punishing blows to their opponents throughout the course of the battle.

Edge: Even

 Senses:  One of the weaknesses you note for both of the dinosaurs here is that both have difficulty locking on to smaller targets - the V. Rex had trouble finding little Ann Darrow after she ran through the jungle and hid in a log in King Kong, and, as mentioned above in the blog post, the I. Rex completely ignored Owen Grady after he soaked himself in some sort of liquid fuel to mask his scent. However, I don't see either of these weaknesses coming into play because the I. Rex is definitely big enough for the V. Rex to notice, and the V. Rex is not going to douse itself in some scent-masking chemical to get the drop on the I. Rex. They both have keen senses of smell and an even higher killer instinct, and those will be the driving forces guiding them through this battle.

Edge: Even

 Other:  The I. Rex has an undeniable advantage with its useable arms (in sharp contrast to the V. Rex), but I still think people are giving that trait a bit too much credit. The arms are still small and the V. Rex still has a ton of scaly armor to contend with, so it's not a guarantee that the raptor claws will just shred right through. Remember, Skull Island has its own form of uber-evolved raptors, too, so if they had posed that much of a threat to the V. Rex, it would have died out. The camouflage and heat detection are quite interesting for ambush purposes - but as I mentioned in King Kong vs. I. Rex (where I voted before I voted here), the I. Rex's ambush powers are only really good for the first strike before all semblance of stealth is lost. The fight is really going to come down to a head-to-head slugfest, and that's where the V. Rex's intimidating size and formidable strength will really make the difference here. The fact that its head and tail can be used as bludgeoning weapons mean that in a fight where two warriors are relying primarily on using sharp teeth or claws to penetrate the armored hide of their opponent, the V-Rex also has heavy, crushing weapons that can inflict blunt trauma through the armor (and possibly break bones or teeth). To me, that demonstrates combat versatility, and that gives the V. Rex the edge.

Edge: Vastatosaurus Rex

WINNER: VASTATOSAURUS REX

I don't want to say no contest, but... no contest. The I. Rex was created, born, and raised in a highly controlled lab setting designed to meet its needs, and it was always fed regularly and given proper care. Sure, that's nice and everything, and probably ensures that it's at its peak physical condition, but that doesn't do it any favors in the combat-readiness department. The V. Rex, in sharp contrast, was born and raised in a hostile enviornment where literally everything is trying to kill you - even trying to get your evening meal turns into a no-holds-barred deathmatch. On top of that, the V-Rex has evolutionary traits that will be (in my opinion) more effective in a fight than the I. Rex's lab-granted traits designed simply to "make it look cool." It's a case of practical vs. flashy, and while the I. Rex's flashy genes may offer some bit of combat lethality (I mean, it escaped its pen and took down PMCs and other dinosaurs specifically hunting it!), they pale in comparison to the V. Rex, who applies its skills to use on a day-by-day basis. That's really what wins it for me in this battle of the apex predators - the V. Rex has that necessary capacity to take hits and keep slugging through, while the I. Rex simply doesn't.
