RhinoRoller

The Rhinoroller is a Titan that can curl up into a ball and can roll with Crash walking on top of it. The Rhinoroller appears in Crash of the Titans and Crash: Mind Over Mutant. In Crash: Mind Over Mutant, when it is jacked it goes into its ball form and cannot attack with its horn until unjacked, unlike COTT when it walks and attacks with its horn even when jacked. It can take down a Scorporilla if it has enough speed. In a level in Crash: Mind Over Mutant, a group of Rhinorollers that are free from Cortex's control can be found in a cave in the Wasteland. In Crash: Mind Over Mutant, Crash can ride Rhinorollers down rails. A Rhinoroller kid will give Crash a minigame when talked to after beating Cortex.

Appearance
The Rhinoroller was created by the mojo to help in create Cortex's army. The titan is very well protected by armor padding that cover its fur and has conical spikes all over its back (noticeably on its shoulders). It was spliced with the DNA of a Rhinoceros, an Armadillo, and a Saber-Toothed Cat (or Smilodon as referred scientifically) given the appearance. It also has a horn projecting from the top of its nose. Given its namesake in Crash of the Titans, this particular titan can curl up into a ball using its spiky armor to flatten its enemies and become indestructible to most basic attacks (normally Crash's punches).

Mind Over Mutant
In Mind Over Mutant the Rhinorollers still retain their usual armor, but have lost the "N" belt was that placed on them. They also seem to have a stronger build and have horns protruding from their heads instead on their nose (similar to that of a bull). There is diversity between the animals with the females looking different to their male counterparts.
