I know, I know, hypothetically, yes, he coudl’ve. But have we ever read or heard or seen any evidence of Shaxx removing his helmet? In that one lore collectible where Mara Sov... [i]invites[/i] Shaxx over, it says “The helmet stayed on.” Now this may just be some suggestively misleading language, but what if its not? What if Mara Sov was [i]hoping[/i] for Shaxx to take off his helmet? Is there some secret he hides behind that one-horned mask? We don’t know what race Shaxx even is, do we? The whole thing seems rather suspicious... Edit: the specific lore entry is The Mark of the Great hunt. And on an added note, it says he’s drinking coffee...but with a helmet on?
Like most of our characters, he is probably ugly as a monkey's ass so he keep his helmet at the tower
