but I like the disney characters more

Disney characters are better, it just wouldnt fit.

Besides, the disney characters gives the game some kind of nostalgic feeling and some kind of magic other characters cant give it, FF characters gives thje seriousness and coolness.

Then it shouldn't be kingdom Hearts.... well at least we can get rid of that Little Mermaid's world

we can call it Kingdom Brains.

Oh come on it will still me magicial

I like that idea. Remember the EGM April fools joke?

Lol this made me laugh.

Toad!? i like the idea!

No! It's the Square Enix characters that should be taken out. Nintendo should buy the rights to the series, replace all the SE characters with Nintendo characters, and give the gameplay a greater emphasis on platforming and the exploration around the worlds of Disney.
