Okay, I'll be spearheading this group review on your character. Quite a few things to note:
History:
There is one big issue here and that is her hearing. Saying that she has hearing that far exceeds that of a faunus is basically going into the territory of a semblance ability. After discussing it with the other staff, we came to the agreement that that is too much and will need to be changed.
Semblance:
The semblance is too OP as it stands. It's basically taking two semblance ideas, creating powerful attacks and constructing objects, and making it into one by saying it's "condensing her aura". We also agreed that this is too much so you will need to pick one or the other and just go with that.
Combat Behavior:
In regards to the echolocation ability, we also discussed this and I'm going to make the call and allow it, but only as a limited echolocation. So please make note of that in the character sheet.
Weapon:
No matter how you look at it, your weapon has six transformations, which is ridiculous. I'd advise you either lower the amount of transformations down or create another weapon. However, seeing that you already have two other weapons, I would advise the first choice and just lower the amount of transformations.
Conclusion:
Overall, this entire character is more or less based off of the ability to hear extremely well. One thing you can do, which would alleviate a lot of the edits would be to just change the semblance to a hearing-based semblance. This would make it so that you wouldn't really have to edit the history and combat behavior all that much. Just something to think about.
I'm keeping this review short and sweet so you don't have to read a bunch and can just address the issues at hand. Feel free to PM me if you have any questions.
