Jurassic Park novel T. rex vs. Indominus rex More on forums.spacebattles.com

Yep, a full grown Indominus ends up being longer than a V.Rex (but is ever so slightly shorter at the hips) More on reddit.com

I find this discussion challenging. We know a bit about the T.rex, but a lot is ambiguous. Comparing it to an outright work of fiction is tricky. If the Indominus was a regular theropod, I doubt it would stand a chance. The T.rex was a tank, massive and muscular. It had the strongest bite force ever seen. In contrast, the Indominus is a bag of bones. It is slender, it has a lighter skull with fewer and probably smaller teeth that don't interlock. They don't cut off flesh. A bite from the Indominus wouldn't cause severe damage to the robust neck of a Tyrannosaurus, unless it struck an artery. While the claws of the Indominus could inflict bigger wounds, if Rexy chomps down with full force, the battle is over. However, with the Indominus being a movie monster, anything is possible. They don't explain its durability, portraying it as a supervillain with no apparent weakness, except for being smaller than a mosasaurus. Invincibility is a killer argument. But assuming it's "just" very strong and tenacious, and more agile than the Rex, it could potentially hurt the opponent. If it could avoid Rexy's jaws, its hands might be a threat. If it could grip its skull and swing about, it might by a small chance break its neck. If it could ram Rexy and flip her, there's a chance to suffocate her. Overall, the fight in the movie had good dynamic, it's just that one animal had absurd superpowers. However, this isn't limited to dinosaurs; it happens with movie humans too. They take a bullet and shrug it off, just like Indo and Spino shrug off a Rex bite. In conclusion, as always, the only theropod that stands a fair chance against a Tyrannosaurus is another Tyrannosaurus. More on reddit.com

As much as I love T-Rex it’s gotta be Indominus. Useable arms are a huge advantage. More on reddit.com
