With a lot of the new information we have gotten lately, I figured I would throw my idea in. Since Dust is a very magical element, maybe the armor was brought to life by Dust (Full Metal Alchemist gave me the idea). It could have been brought to life by Weiss' family, as a way for her to test her skills, or maybe even by Weiss, so she could practice fighting. I am hoping Monty reveals more later. 

I figured that the more powerful Grim use their own kind of dust, either called "Grim dust" or "smoke", etc. So maybe someone who was trying to eliminate Weiss (inside job?) tapped an amount of Smoke into the Giant armor, making it not only animate, but extremely aggressive.
