Yes. The latest Metal Gear model out there. I fought against it a little when I infiltrated Aresnal Gear.
How powerful is it, really?
Quite. It's a humansized unit with 5 mini-particle beam cannons. Its made from pure Titanium. The GAY stands for "Grand Arsenal armY". Casually called "Gonna whoop-Ass a beeYotch today!"
Hahaha. You said gay and ass in the same paragraph.
... your sheer idiocy is also the reason why I can't let you fight GAY.
