True as well, despite the hit to his IQ in KH2, Sora isn't that dumb. It's mostly on Mickey and Yen Sid though no one could've predicted MX's Aizen-level planning in DDD.
I do still wonder what DDD's original ending was though given it seems to hint at Sora falling to MX.
anagram, im sorry, but theres one thing i can't agree with there. as much as I love MX, as much as he is my favorite villain ever, NO plan is at aizen level. none. ever.
now that thats outta the way, I too wonder on the original ending. I feel like nomura was going to make sora a darkness, and got screwed out of a major plot point by disney. but i'll never know.
