This ones fun. I have to give the majority to Big, there's just so much crap in that thing. Escaflowne is my agile, and it can fly, but it has no idea what the Big O can do and Big does have some experience with flyers. I see the first strike, Vaan using his blade against Big O, Big O blocks with his Arms and then shoots that beam from his forehead or the chains from his waist to prevent movement.
Closing.
