I have been wondering about this for a long time now and I wanted to know what you guys think. Who do you think the kingdom hearts original characters belong to? Disney, Square, or both? Reminder that kingdom hearts characters include Sora, Xehanort, Hayner, heartless, Organization XIII, etc. As for me I guess I choose both, though Im still not sure . They're original characters made by Square but have a strong influence on the Disney worlds of Kingdom Hearts.
