Indominus rex is a LEGO dinosaur, usually made of multiple parts like other dinosaurs. She is the main antagonist in the Jurassic World theme.
The Indominus rex is a genetic hybrid dinosaur appearing in the film Jurassic World. She contains the base DNA of a T. rex, as well as DNA from other modern animals such as cuttlefish and tree frog, these modifications give it unique abilities such as the ability to camouflage itself. She also contains Velociraptor DNA, giving it increased intelligence and the ability to comunicate with Raptors. Perhaps the most terrifying aspect of her intelligence is her tendency to hunt not for survival, but for sheer pleasure, killing for sport.
During the events of Jurassic World, she escaped and went on a rampage across the island, the ACU were unable to stop it, forcing Owen to use his Raptors to try and track it down and kill her. This ultimately failed when the Indominus rex caused the raptors to turn on the humans. Later, however, Owen managed to re-establish the bond with his raptors and made them turn on the Indominus rex. The Indominus rex killed the Raptors except for Blue, and possibly Delta who, with the aid of the freed Tyrannosaurus rex, manged to push the Indominus rex to the moat where she was killed by the Mosasaurus.
