Igaunasaurus-Rex (I-Rex) 1

Okay, so the Indominus-Rex is Jurassic World was cool, but maybe on an alternate Earth where iguanas became carnivorous apex predators this I-Rex would be as adaptable to blending in with it's environment as the Indominus was, giving this creature an evolutionary advantage of being able to take down it's quarry due chameleon abilities. On this alternate Earth the Iguanadon and the T-Rex never evolved. Imagine if on this alternate Earth dinosaurs never died out and continued evolving into hominid species.

In this photo you see it the creature not bearing its teeth and a somewhat playful expression on its face, but this creature is deadly, so if you go hopping off to a parallel Earth and encounter it do not underestimate this predator!
