What happens when you get the mandatory giftmons (latio/as, lucario,

Lucario is not mandatory, however XY keeps a PC box hidden until you capture Xerneas/Yveltal. Presumably ORAS does the same with Latias/Latios/Rayquaza, and SM with Solgaleo/Lunala. BW1 just lets you skip catching the box legend and has them appear postgame.

I feel like I can access all 32 boxes at the beginning of the game, at least in SM. I started Sun again just recently and transferred every box right at the beginning. Are you telling me a 33rd box appears after you catch solgaleo? I feel like I would have noticed that. I actually just passed that point last night, imma check

No still 32. Does every box have to be full for another to appear? Wouldn't make any sense as per the box arranging screen where the 32 boxes completely fill the screen.
