Jp Omega T Rex by hellraptor
Chaos Genesis: Purebred, dominant Tyrannosaurus rex

Tyrannosaurus rex: Massive, bipedal, predatorial carnivore.

Length: 50 ft. Weight: 10 tons Diet: Meat

Behavior: Purebred and purely terrifying, the Omega T-Rex is by far the largest, most ferocious predator to ever walk the earth. Genetic fine-tuning has turned this large Tyrannosaurus into a hyper-aggressive lizard – the ultimate Tyrannosaurus rex. No longer does it possess the inherent weaknesses of a genetically unaltered T. rex: it is faster, stronger, has better eyesight and sense of smell, and has somehow developed a much more aggressive temperament than its predecessor. Brilliant coloration and unnatural markings easily distinguish this colossal lizard as a mutated Chaos Effect variety. Enormous jaws open wide to gulp prey down whole. Omega T. rex: the incontestable tyrant king of the dinosaurs!


  • Unlike most of the other Chaos Effect animals, this dinosaur isn't a mix of several animals. It is only labelled as a "genetically enhanced Tyrannosaurus rex".
  • This is one of the two biggest dinosaur ever produced in the various JP toy lines. The other one is the Bull T. rex, which has the same mold as the Omega T. rex.
  • A boxed sample of this toy usually fetches quite a high price: usually around $75-125.
  • It is stated on the back of the figures box to be the most dangerous animal to have ever lived, even more dangerous than Spinosaurus or Ultimasaurus.
