I'm amazed how the horns of the Nitrams and the horns of Dammek are still intact from their cumbersome size, yet Equius's right horn is already broken

Well, Equius is pretty strong and he builds robots just to beat them up, chances are he broke them doing something like that. Then again Dammek is constantly dealing with weaponry so it really is a miracle his horns are intact. I’d imagine they’re not easy to break though.
