Gundam 00 The Movie

[Illrenmazou]

Official Linearts:

00 Qan[T]: I'm really loving it's simple yet elegant design (Kudos to Ebikawa). It looks like it's GN Fang rack can swivel from left to right. And the rumors are right, the second GN Drive is mounted on the "sheild" with the swivel arm linking it to the other for the Twin Drive System.
Zabanya: Thank goodness the box feet from Cherudim are gone. Looks good but those equipments, which looks like weapons containers, sticking out of it's ass looks awkward.
Harute: "What happened to the 0-Riser?" I guess this will answer that question <_<. I guess the design may grow on me.
Raphael: I really hope those things on the shoulders are parts to form another MS. It better have those obscure equipments like extra arms. It's not a Tieria Erde Gundam without those!

I'm pretty sure that they are armor parts. It looks to me like they are (in S1 therms) a Nadleeh to Virtue conversion. So instead of purging armor, it actually attaches to it.
If you look closely at the backpack, you can make out a front skirt and sideskirts and probable bigass arms. Maybe on the backside there is a backskirt and maybe even a chest armor thingie.
