Ultimasaurus Rex

The ***Ultimasaurus Rex*** is a hybrid dinosaur which appeared in several KB works, usually as the villain.

## Biology

The *Ultimasaurus Rex* is a chimerical superhybrid dinosaur which possesses body parts from almost every known form of prehistoric reptile and dinosaur. It has the bipedal body of a large theropod, presumably of a *Tyrannosaurus*, and on its back it had a large sail from a *Spinosaurus*, two rows of plates from the *Stegosaurus*, and armor plating from *Ankylosaurus*. The plates and armor plating ran from its long neck onto its long tail, which ends with a thagomizer which combines those of *Stegosaurus* and *Ankylosaurus*. The large armored shoulder spikes in front of its body resemble that of the ankylosaur *Edmontonia*, while the back plates gradually become sharp spines as in *Kentrosaurus*'. Its long neck is similar to that of sauropods like *Brachiosaurus*.

Its head is heavily armed, adorned by the large frill of a ceratopsian, the domed head of a pachycephalosaur, the crests of a *Dilophosaurus* above its eyes and the crest of a *Parasaurolophus* protruding from behind the frill. The head has three horns: two large brow horns at the bottom of the ceratopsian frill, and a large horn on its nose as in *Styracosaurus*'. The *Ultimasaurus Rex* had a sharp, hooked beak at the end of its snout and a large row of razor-sharp teeth belonging to a mix of carnivorous dinosaurs such as *Tyrannosaurus*, *Spinosaurus*, *Allosaurus* and *Troodon*. Its jaws open very wide at almost 180 degrees.

The superhybrid's forearms are long, which enables the creature to even walk on all fours. Its hands have long, sharp blade-like claws akin to that of *Therizinosaurus*, and the first digit is a shorter claw resembling those belonging to *Baryonyx*. Its hind legs come from large theropods, and it also has the killer claws on its feet inherited from dromaeosaurs/raptors. The *Ultimasaurus* *Rex* has two extra limbs - a pair of pterosaur wings - which erupt from the shoulder blades. It is also an adept swimmer: when swimming, the superhybrid's limbs form into flippers which resemble those of the Plesiosauria.

Its intelligence is 100 times higher than that of a *Velociraptor*'s.

## *Godzilla: Dino Destruction* version

The superhybrid first appeared in the ending of the 2011 KB film, *Godzilla and the T-Rex of Tokyo*. It later appeared as the final antagonist of its 2013 sequel, *Godzilla: Dino Cyber-Domination*.

## *Valley of the Dinosaurs* version

The *Ultimasaurus Rex* is the main antagonist of *Valley of the Dinosaurs: Journey to the Centre of Earth* (2015). It tried to attack the group of main characters who are trying to escape from the Center of the Earth. Eventually, the superhybrid falls into an erupting volcano, where it is incinerated upon landing into the molten lava below.

## Trivia

* The original Ultimasaurus would eventually inspire the appearance of another hybrid, the *Pachygalosaurus*.
* The *Ultimasaurus Rex*'s roars are recycled from the *Jurassic Park* T. rex (*The Lost World*'s version), the Suppa Alien, the T. rex from *Carnosaur 2*, Sharptooth from *The Land Before Time*, and the *Carcharodontosaurus/Mapusaurus* from *Dinosaur Planet*.
