Ubese Thorn-Back War Dragon

Ubese Thorn-Back War Dragons were huge, violent beasts which had horns on their heads, shoulders, feet, and tail plus an extra two on their hips. They were introduced to many populated worlds during the Clone Wars by the traveler Nomad-Damon and soon after Jedi Knights attempted to tame them with some degree of success. When the Galactic Empire came to power many of these creatures were destroyed but some survivors disappeared or were sold to wealthy citizens.

Behind the scenes
Ubese Thorn-Back War Dragons were created by Mark Rehkopf, a Star Wars fan, as part of the Design An Alien contest held in the Star Wars Galaxy Magazines. The entry was picked as the overall winner in the 16 years and older category but it is not known exactly how canon the creature is.
