Lighting bending has some nice versatility. Correct me if I am wrong, since I am no physicist. Couldn't lightning bending be used to bend metal too? Magnets and all that stuff. Then there is the Railgun move, pretty sure nothing in Avatar could bet it's speed, range and damage potential. The question is, would that work in avatar? I have no Idea. There must be more that could be done, I am sure, but not on what.
