If I had to pick from just these four options (which I personally feel is a little limiting because there’s more than 4 films from the past 2 years that I think have Kingdom Hearts potential), I would go with Encanto. However, as much as I love Encanto, and as much as I would love to see a world for it in Kingdom Hearts, there is a film that I personally love even more than Encanto that’s not on the poll: Raya and the Last Dragon. I personally feel that Kumandra would make an excellent world in a Kingdom Hearts game. While a world based on Encanto would surely be exciting and fun, I personally think a world based on Raya and the Last Dragon would make for an even better and more diverse world with the potential to be rather expansive. Now, if both films end up getting worlds or representation, that would honestly be the best thing I can think of. I love both Encanto and Raya and the Last Dragon, and I think both absolutely deserve to be represented in Kingdom Hearts. But if I had to pick one or the other, I’d have to be in the minority and pick Raya and the Last Dragon. Again, I love both of those films, and either one would be incredible to see in Kingdom Hearts. Who knows? Even if it’s not both in the same title, maybe both of them will end up being represented in Kingdom Hearts eventually. That would be amazing in my opinion.
The TLDR version: If picking from these four options alone, I would choose Encanto. However, I would personally prefer Raya and the Last Dragon more than Encanto. I love both films, though.
