>>52879266Aside from the whole 'the futuristic/scifi elements of area Zero make the most sense with Violet' thing mentioned above, there's also a bit of dialogue that everyone seems to overlook. At the very beginning of the game, Koraidon/Miraidon saves you from the Houndoom and you meet up with Nemona outside the cave, your 'Raidon loses energy and slumps back down from Battle 'form' into its default 'form'.Nemona then comments 'Wow, it transformed! It's like a totally different Pokemon!'; Arven comments on its change of appearance as well. The catch: the only one of the two Legendaries that actually transforms is Miraidon (its legs suck into its Hadron Engines, it gets that sparkly blue energy on its underside, and it gets those lightning bolt-like antennae on its head), while Koraidon doesn't really change physically at all (it just stands upright and puffs out its dewlap). Nemona's and Arven's comments on your Legendary 'transforming' and 'looking totally different' only really make sense with Miraidon, and thus the dialogue only makes sense in Violet. This, along with the more coherent scific themes in the final area, the fact that Turo actually looks more like a traditional Pokemon Professor than Sada, the parental abandonment plot which works better with Sada taking baby Arven and abandoning Turo to his obsession (rather than having the father be the one to run off with the kid after the mother basically just ignored the child she carried for 9 months and unceremoniously pumped out only to favor Koraidon over Arven instead in Scarlet), and other little details all seem to suggest the story was written for Violet first, then tweaked for the inverse in Scarlet.
Of course, this is irrelevant, because Pokemon has established that the series is a multiverse, so both versions are simultaneously canon and happen on parallel timelines.
