Intro. Laboratory Creation: Indominus Rex is a hybrid dinosaur, created in the laboratory by InGen scientists, led by Dr. Henry Wu, by combining the DNA of several species, including Tyrannosaurus Rex, Velociraptor, Giganotosaurus, Carnotaurus, and even modern animals such as cuttlefish and tree frogs. Isolation and Intelligence: The Indominus Rex (meaning "Indomitable or" "Ferocious" King) is shown living in isolation in its enclosure since birth, which has contributed to its aggressive temperament and heightened predatory instincts. The Escape: Its impactful introduction into the main storyline happens when the main characters, including Owen Grady (Chris Pratt) and Claire Dearing (Bryce Dallas-Howard), investigate it more closely. Indominus demonstrates higher-than-expected intelligence, feigning an escape to lure security personnel into her enclosure, and then escapes, initiating chaos and threat
