Now we've all seen the data of the Gigantic Exceed says its the form of the true power, but...
...I believe it's not just limited to the Giant.
Remember, Caerleon is believed to refer to Archanfel when he says there was one who could use powers of the other zoalords. Now if the Gigantic armor was designed to defeat Archanfel, and Sho was linked to all that data(probably Archanfel's data as well) in the advent ship, the armor couldn't be limited to a giant mode. I believe if Sho fought other zoalords in Exceed mode, the armor would adapt to their abilities. Example: If Sho fought Li Yentsui, Sho should be able to see his portals and possibly maybe able to create to his own.
The only zoalord(so far) that would not apply to this theory is of course Waferdanos, since he was a different experiment all together.
