Onu'zun's "updated" model.
- He currently uses a model not found on any other troll in the game, with the skin color of an ice troll but with the leaner body type of a jungle troll, rather than the bulkier model used by most other ice trolls.
- Much like Surkhan and Ghaliri, some kind of error appears to have occurred with his model texture following the player character revamp in Warlords of Draenor, possibly as a result of the above.
- This is due to the change in texture mapping. Originally, all troll models able to equip armor (forest, ice, and jungle) were able to exchange textures with acceptable results. The newer jungle troll model uses a different system for texture placement, thus leading to the ice troll skin being inapplicable.
