I. Rex vs. Ultimasaurus

Looking back, I remember that Jurassic World isn't the first case of hybrid dinosaurs we've seen in the Jurassic Park lineup. I was going through my old toys one day and found two of my favorites from when I was a kid; my Paradeinonychus and my Velocirapteryx. These two are from a 1998 series of JP toys known as Chaos Effect. Sadly, the series was discontinued due to poor sales and they never released their greatest hybrid, the Ultimasaurus:

Created to be the ultimate dinosaur, I would be quite interested to see this beast clash with the Indominus Rex. Who do you think would win that battle?
