Well, if we're talking about powers that can break the universe, we pretty much all have them. Sound waves, velocity, gravity, instant transfer of matter, etc. Its all about how much of it you use. For instance, just taking Aoi as an example, if she creates a powerful enough soundwave at the right frequancy, she could cause anyhing to vibrate itself appart. This, however, is not only out of her league, but she wouldn't be smart enough to know that.
Oh, and the vibration thing includes internal organs. She could literally pulp you from the inside without you knowing... well, it is within the power of her semblance, but once again, she isn't that smart, nor powerful.
