What if there was a form of bending called matterbending? The person who possesses this ability would be able to bend anything. There would be no limitations to what this person can bend. Since this ability can cause mass destruction, don't you think it would be cool if only the Avatar could possess this ability but can only access it in Avatar State? That would be so EPIC if it existed in the Avatar world. The Avatar would not need to count on the four elements alone because they can bend anything, anywhere.
Tell me what you guys think.
