Turner had the ability to interact with atoms, change them, and destroy them. With his power, Turner could not only do things like changing matter from one state to another, he could even change matter from one material to another. He could manipulate the molecules of silver and make it turn into gold. He could manipulate the molecules of iron and turn it to air. He could touch a metal bar and have it turn to a wooden stick. This was what Turner's ability allowed him to do.
