Now one of you engineers need to figure out a way to make a battery for these rings!! I'm looking at you santoro.
So...if you did get a ring, what would be the first thing you would materialize? A spaceship? Space station? dinosaur? Girlfriend?
Personally I guess I would make myself an uber GL Ninja suit complete with uber GL Ninja Sword and shurikens and Ninja magic. But thats just me.
