I hope I don't have to explicitly say that breaking things by sheer will is... odd, to say the least. But if it's something that can't be used on living things (and therefore instantly killing them), then I personally don't see much issue with it. I'm just curious regarding what you would consider a living thing, since some people can take the form of non-biological material, or forming chitin armor (such as Valjean). That chitin armor isn't a big deal if it can be broken off of Jean without actually endangering his life. Or maybe it does. I don't care. It really depends on Allen if he wants his character's armor being penetrated.

I only take up issue with the character, since blood-red hair doesn't naturally occur. Are those blackened fingertips and veins correlated with her shattering superpower? Otherwise, that seems really far-fetched too.

This is irrelevant, but I find it odd how there are so many destructive powers being made. There is not a lot of building or simple modification or situational abilities.
