I wonder if the AGE-FX's design is similar to the 00 Qanta on purpose. Because the 00Q didn't get much screen time, but we all thought it was going to be in the whole movie, and were pretty disappointed when it wasn't. I wonder if this Gundam is meant to make up for that (kinda).
Like, Kanetake Ebikawa just said "Damn it, I won't my good stuff to actually have screen time!"
