It's definitely the AGE-2. The feet, the skirts, the knees... And more noticeably, the spoiler on the back. Also, note the lack of wings or any form of large attachments on the shoulders - doesn't seem like the Normal or Double Bullet. AGE-2 Pirate, perhaps?
Really hoping for a third wear for the AGE-2, it would be awesome.
EDIT: The AGE-3 released some form of smoke canisters when it was pursued by a Danazine before docking. Any idea where those came from? (On the AGE-3, that is.)
