So if you had an element of choice...what would it be?

Me I personally favor the element ~Darkness~
I would use it for many reasons, that are too great to list, and I like it because it seems as if it is most powerful, and unknown to man-kind, that is my element...so what's yours?

fire
darkness
grass
electricity
water
wind
earth
metal
normal
pyschic

^ these are some of the choices, but you can choose any element you wish, Explain why you like this element and what you would use it for!
