Oh, totally random thought.
I've been thinking about superhumans and how a body must have to evolve to adapt to someone's powers, and how that would impact Dinah. And I think there might be some things she should have that, as far as I know, she never has.
Enhanced hearing. Dinah can make sounds beyond the range of human hearing, so doesn't it make sense that she should be able to hear that? Not a "Superman" level of enhanced hearing, but still a wider range than a baseline human.
And shouldn't Dinah be a bit more durable against blunt force? Sure, she can direct and aim her sonics but her body would still need to be durable enough that she doesn't rip her lungs and throat apart with her own powers. Again, nothing like a Superman level of durability, not even close to bulletproof, but able to take, I dunno, a baseball bat blow easier than someone her size should be able to.
