Rexy is a female Tyrannosaurus rex who appears as a major antagonist-turned-anti-heroic deuteragonist in Jurassic Park, a recurring protagonist in Jurassic World and its sequels Jurassic World: Fallen Kingdom and Jurassic World Dominion.
Rexy is a large 13.5-meter-long (44.3 feet) and 5.2-meter-tall (17 feet) adult female Tyrannosaurus rex with a dull gray and brown color scheme with degradation color zone running down her neck, back and tail. In the first film, she appears to be quite robust and muscular, though her appearance in the fourth and fifth films has changed noticeably, with the stripes on her back having become very faint, her skin tightening, the shape of her head morphing with age and her body becoming thinner. However, she somehow regained mass after Jurassic World's downfall, becoming more robust by 2018. Rexy displays scars all over her body, most notably three large gashes running down the right hand side of her neck and face from what she received during a fight with two Velociraptors in 1993, making her easily recognizable.
Powers and Abilities
While she possesses physiology and powers of the extinct Tyrannosaurus including strong jaws, Rexy strangely had bad vision which explained her tendencies to attack any moving objects, unlike the said extinct species and believing that these dinosaurs can be avoided by freezing in one spot until they turn away and leave. How Rexy had bad vision was due to the defect on her cloning process. Also, unlike the extinct Tyrannosaurus, Rexy can also run much faster as she was able to briefly catch up to a jeep.
In Jurassic World: Fallen Kingdom, after being transported off Isla Nublar due to a volcanic eruption and later freed from Lockwood Manor along with all the other dinosaurs, Rexy is seen breaking into a zoo exhibit and roaring at a lion, who stands its ground.
Rexy and all the other dinosaurs of the original Jurassic Park we're created out of Frog DNA.
