Three things, but firstly-
Who could hate this?[hider= warning, cute sloth]

The others being, and don't take this the wrong way- the line between allusion and plagiarism; and I'm getting Mary Sue vibes?(I hope I'm wrong.) Specifically: Hyperbole or just OP? Also, for being proclaimed to be "not proud and haughty", he's totally haughty and proud. (Although I can understand if that was the point. But the dry sense of humor isn't surprising really. It'd be more unexpected if he had a rather boisterous one.)
Sorry, but I felt something needed to be said. Plus I don't like leaving the thread dead for too long. I'm a bit of a spazz, for that I may have to apologize in the future.
Also, just so it doesn't slip past anyone's notice, no offense [@EmzyOfNeverland], but rather I want to have your back on this- how is he able to just form Dust at will without using a Semblance that's meant to do that? I'm baffled, so please inform me if I'm missing something.
Also, fair warning [@Crimmy], Aven will inevitably come at odds with your character as he stands now. Like, even if I wanted not to, I couldn't stop it because of the way Aven deals with things and how your character is. Not saying you, like, need to change anything, just letting you know.

I'm not trying to be mean, I just don't want certain issues to rip the RP apart from the inside if that can be helped.
