RWBY Rex (also referred to as the Raptor[1]) is a recurring non-canon character originally featured in Monty Oum's Twitter feed photos. He has made sporadic appearances throughout the series as an in-joke and easter egg.


RWBY Rex appears as a small to large sized dromaeosaur, with a beige coloration and deep green eyes. He has a bulky body, with a light underbelly, and long, spindly fingers, each tipped with a large claw.

Much like other members of the Dromaeosaurid, or raptor, family, this dinosaur has a sickle-shaped claw. This is an iconic trait of this dinosaur family, of which the most well known genus is Velociraptor, made famous in Steven Spielberg's famous 1993 movie Jurassic Park.


RWBY Rex's debut was on Monty's Twitter feed, when he posted an image of Ruby Rose and Weiss Schnee riding a dinosaur, joking that he had been awake for too long.[2] RWBY Rex has subsequently appeared in several similar tongue-in-cheek scenarios:


  • The Raptor is a default model in Poser, the program used to animate RWBY's first three volumes.
  • In the band picture, the name "RWBY Rex" is written on Yang Xiao Long's drums; this may be the official name for RWBY Rex.
  • The size of RWBY Rex has varied widely between his appearances; in its first few artworks it was large enough for two of the girls to ride like a horse, but in the picture with Jaune Arc it appeared about the size of a small dog.
  • Contrary to the "rex" suffix, the dinosaur's character model appears to look similar to the dromaeosaurid dinosaurs known as Utahraptor and Deinonychus, which were not related to Tyrannosaurus rex.
