While we previously showcased Neltharion's fully armored model, a newly datamined version removes the helmet to better show his unique facial features, including a scar that was absent from his appearance in Dragonflight Legacies, but visible on the model used during Cataclysm. Note that the actual model includes shoulder armor, which has been removed from the lower two screenshots in order to better highlight the face.
Aside from the obviously draconic eyes, one standout feature of the model is the scar running through his brow. While the same scar could be seen on his original model from Cataclysm, it's conspicuously absent from his appearance in Dragonflight Legacies, suggesting that the scar was earned sometime after his descent from Neltharion the Earth-Warder into Deathwing the Destroyer.
Notice the missing scar featured in his more recent models. Unfortunately, players cannot copy this look, as the hair, scar, and eyes are all unique to Neltharion.
However, players may be able to obtain his plate helm and shoulder armor in Aberrus. From Dragonflight to Cataclysm.
