My point is that, since waves are also vibrations, holy shit the kinds of stuff he could do. Plus being able to freeze things and heat them up? He could cause explosions by exciting hydrogen atoms. Alter light (light is particles... AND waves) and sound. Even minor telekinesis by pushing things with vibrations. Plus earthquakes and tsunamis. Hell, I don't know about lightning yet, but it's caused by exciting molecules in the air right? Yeah... Scary.
