In a huge abandoned warehouse in the dock's of Keystone, these three face off, everyman for himself, there are boxes, crates, cranes,forklift's and loads of shadow. Lots of places to hide and operate here.
Give your reasons on who would win out of these three.
I personally think Nightwing or G.A. as Nightwing would go for Red Arrow first then Green Arrow, or Green Arrow will wait for Nightwing to pick of Red Arrow, and then make his move.
But overall i think nightwing will dodge arrows and use a varaity of gas and bombs to outsmart his oponents.
