I knew me going into detail about this was coming.
Let's look at "one dimensional" Donald:
- King's gone. He said "find the key bearer". Donald goes.
- Traverse Town. A kid has the key, he's worried about his friends. Donals says he's sure he'll find them by coming with him and Goofy, then openly admits in front of the camera (and Goofy) that he doesn't know and doesn't care, he just wants the boy to come with them.
- Deep Jungle happens. A bit I find important here is that the reason why Donald was refusing to go into that world wasn't because nobody was there, buyt merely because he doubted the KING was there. He wasn't ruling out that Riku and Kairi could've been there, he just didn't care. Sora and Donald aren't on speaking terms. Donald wants to leave him there for good. Tarzan and the power of *&&X% reconcile the two.
- Traverse Town. Sora finds Riku, the friend he was screaming about the entire time. Donald refuses to let him come along.
"Come on! He's my friend!"
"I don't care!"
- Hollow Bastion happens. Donald and Goofy lave Sora, because their purpose was always to support the key bearer.
They will later come back to his keyless side because of their newfound friendship. This is also the first time Donald'll say "all for one, one for all" to Sora.
We can surmise a few things from this, aside from the fact that Donald hardly cares about stuff.
He was never truly Sora's frined until the Hollow Bastion scene. Throughout the game it becomes clear that he's just tagging along, and at times he and Sora clash. Which is obvious, they've just met and now they have to endure a perilous journey together. Still, when you look at things from this perspective you'll see Donald only does stuff because he's working on his goal, and will ditch or refuse Sora's requests just because they aren't useful to him.
Again, he was (possibly) leaving two kids on a jungle. He didn't care whether they were there or not. And when he does tag along, it's only because he found a gummi.
I know the way Donald and Goofy ditch Sora has been met with some criticism throughout the years, but to me it seems justified when taking all of this into account. Abd it makes their face turn when they come back to Sora's side all the more earned: it's the first time they'll disregard their main purpose to come to Sora's aid, because they realized they're his friends.
This is how Sora and Donald's friendship was forged, and I adore it. I wasn't kidding when I said it's a character arc way better than others the series gave us. I certainly buy this friendship more than eating ice cream while looking at the sunset over and over.
My only complain is that Goofy just seemed there for the ride.
This is nothing new. The subsection of KH fans that don't like Disney has existed since like KH2. What's worse is that these people were somewhat catered to in the late 2000s with Days and BBS de-emphasizing characters more than ever before. I've grown to love all parts of KH, no matter how cringey or dissonant, but I've never felt like Disney was the problem.
Yeah.
People like that were always there, but when KH went through its "only main characters" period, they even felt entitled to that.
If you tuned in from KH II onwards, I can see why some would think of Disney characters as mere accessories to the main story.
