Odd question to ask, but do you have any specific headcanons about Sora's father and mother? Like if they may be pre-existing SE characters? (i.e. I've personally always thought Sion and Dominique from the Bouncer as his parents since the former looks like an adult version of Sora and was the basis of his character model and the latter because she's the aforementioned character's love interest).
I don’t actually have headcanons about what pre-existing SE characters they might be, but I enjoy hearing about other people’s ideas! I looked up Sion and Dominique, and I can see why you think they’d make good candidates for Sora’s parents. It’s interesting to see how Nomura has used his ideas and character designs throughout his career.
I do have a few headcanons about Sora’s parents though:
Well, for one, they raised Sora, the human embodiment of sunshine and joy, so they’re probably pretty awesome themselves.
Sora mainly takes after his father’s physical appearance... but he has his mother’s eyes. I just really like the idea that his eyes are like his mother’s (maybe it’s the Harry Potter fan in me?)
They worry a lot about their son going off on often dangerous adventures, but understand why he feels like he has to help the worlds. They’re good people, and their son takes after them, especially in terms of his selfless nature.
They feel awful about forgetting Sora in KH2. Hearing about his disappearance at the end of KH3 hurt, too. That right there is a parent’s worst nightmare, and Riku and/or Kairi had to break the news to them...
Sorry to end on an angsty note, I just can’t imagine how they would feel about their son disappearing like that, especially because he’s their only child... I know the series proper needs to focus its screentime on the core characters, but I like thinking about what happens behind the scenes anyway.
