Looks like my beloved mount that took me about 5 years to acquire and is one of the most unique is a Timewalking vendor mount (red tint).
Come on art people, show this mount color some love by giving the fel-green eyes and mouths a bright red color that would go perfectly with the body color change and its new name, since it’s Fleshripper, not Felripper.
The Ur’Zul is created using fel magics, hence why it’s eyes & blood are green.
It being made of fel doesn’t dissuade from it ripping into flesh though — as we know from many, MANY demons & fel-corrupted beings of WoW.
Additionally — Immense amounts of Fel turning beings skin to red isn’t uncommon either, as we’ve see from the Fel-orcs on Outland; along with Gul’dan himself when he channeled immeasurable fel-power at the Nighthold when we faced against him.
So I’d say the model makes sense, given its origins & such.
