Which gets into another bit of Conspiracy. I believe that, at some point, the whole "Cell" thing from Zygarde was NOT the plan. Considering that in X and Y both Thousand Waves and Thousand Arrows were coded into the game with the same power and accuracy as Land's Wrath, and Core Enforcer was nowhere to be seen, I think the original plan, due to there being TWO unused Kalos game slots, and there were ALSO two unused slots for Zygarde forms in Gen VI's Coding, was that Zygarde was going to get 2 version exclusive forms similar to Kyurem, for one Land's Wrath would become Thousand Waves, and for the other it would become Thousand Arrows. Whatever the case, the whole plan was scrapped sometime before the general plot of the second part of the XY anime series was made, which instead used the Cell idea that by then they likely were already deciding to shoehorn into Sun and Moon, because they wanted an entirely new region for the 20th anniversary so Kalos was going to be left to hang. The process is pretty awkard coding-wise, because they just through both signature moves into the Zygarde Cube, made Core Enforcer, and coding-wise there were now FIVE Zygarde forms total, since how it was coded the Aura Break and Power Constuct versions of 10% and 50% Zygarde are considered entirely separate forms instead of being an alternative ability(Battle Bond Greninja and Own Tempo Rockruff as coded in a similar way)
