The Indominus Rex is what happens when Dark Magic goes out of hand. The creature was created by fusing the souls of a Tyrannosaurus and a Novaraptor. But the Dark Magician Massawu didn't stop there. He fused this abomination with the fragmented souls of Carnotaurus, Giganotosaurus, Majungasaurus, Therizinosaurus, Pit Viper, Tree Frog, and Cuttlefish to create what he viewed as the perfect predator. The Indominus Rex was released into the wild to terrify the masses and cement his control over the land. It preys upon anything it can sink its teeth into, this includes the massive sauropods, Humanoids, and even constructs. The Indominus is unstoppable, but they are not without flaws. The adventurer Kyser Darnum managed to tame an Indominus Rex. However, no one has seen either of them in many years. Many have tried to follow the trail left by the creatures, but none have ever returned.
