Tyrannosaurus Rex (formerly known as T-Rex) is the main protagonist of 20th Century Fox's date of birth 1993.


An apex predator capable of reaching thirteen meters in length, Tyrannosaurus Rex was the largest species of Tyrannosaurid, and was intended to be the star attraction of John Hammond's vision for the original Jurassic Park.


Seven Tyrannosaurus rex were cloned by InGen scientists in their compound on Isla Sorna, circa 1990.

A female Tyrannosaurus was transported to Isla Nublar to star as the main attraction of Jurassic Park, inhabiting the Tyrannosaur Paddock.[2] The paddock was originally intended to be inhabited by an adult, and a juvenile Rex, though it is unknown if a juvenile was ever transported there. Nublar's Tyrannosaurus Rex was supposed to have been seen by InGen's endorsement team on their tour of Jurassic Park.

The individual from the original park, was eventually captured in 2002 and placed in captivity in Jurassic World on Nublar, residing in T. rex Kingdom. During the climactic events of the 2015 Isla Nublar Incident, it was released from captivity, and fought, and helped defeat, the genetically modified hybrid Indominus rex.[6] This same T. rex became wild once more, though became threatened three years later during the volcanic eruption of Mount Sibo.[7]
