The main plot for Kingdom Hearts has seen many Disney characters being very influential in the franchise. For the fans, most of them agreed that Winnie the Pooh is the most highly regarded Disney character to ever exist in the Kingdom Hearts 3.
Unfortunately, there is now a big chance for Winnie the Pooh to miss out on being part of Kingdom Hearts 3. This is evident with Square Enix strong statement that says Sora will be more matured in the upcoming sequel.
With maturity, there can’t be any room for childish figures hence there is no way for the lovely bear to be part of Kingdom Hearts 3. Winnie the Pooh is by far the most innocent Disney character ever and he can’t there is no way he can blend well with the violence that is to come in Kingdom Hearts 3.
Of course, the above is merely a speculation and it should be taken with a pinch of salt. Who knows? Square Enix might have something disturbing in store for Winnie the Pooh in Kingdom Hearts.
