The Omega T. rex is a toy released in 1998 for Jurassic Park: Chaos Effect. The toy features a repainted survival pod, and the same sculpt as the Bull T. rex.


  • 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 biggest dinosaurs ever produced in the various JP toy lines. Only the Jurassic World Fallen Kingdom Super Colossal Tyrannosaurus is larger.
  • It shares the same mold as the Bull T. rex from The Lost World toyline, which was later retooled for the Jurassic Park 2009 toy line.
  • No boxed samples of this toy are for sale at this time. Used samples usually fetch quite a high price, around $300-500.
  • It is stated on the back of the figure's box to be the most dangerous animal to have ever lived, even more dangerous than Spinosaurus, and only matched by the Ultimasaurus.
