Rhinotaur

Rhinotaurs are race of strong humanoids that are loyal to Aslan in the world of Narnia. They are described to be part-man, part-rhino. These creatures are meant to be tall and muscular in size. Like a rhinoceros, Rhinotaurs have long, sharp horns to bash their enemies to the ground. They are able to break through trees and walls with their might.

Concept Art Appearance
Rhinotaurs were mentioned in the concept art of the Disney adaption film, The Lion, the Witch, and the Wardrobe, but they did not appear in the film. Instead, they were replaced by ordinary rhinos that took place in Aslan's Army in the 2005 film. It's possible that these creatures might appear in the future adaption movies of The Chronicles of Narnia.
