Namine an angel?

I would say she's probably a metaphor for one, but as far as in-continuity canon goes I would say not. As far as we know, actual angels don't exist in KH. Like them saying she's a witch. She's not actually a witch, they just call her that because... well... it sounds insulting and they don't understand her.

 

This is not quite true
Joshua is in KH3D

 

I don't know anything about TWTNW so I wouldn't know. And even still, it's clearly something they don't plan to build on.

 

I wouldn't say she is, but there's not really anything else to describe her by.

She was called a witch because of her ability to mess with Sora's memories and use them to her likings. I'm sorry but I cannot blame them if they consider her as a witch. Messing with someone's memories is rather fearful.

As far as abilities go, she can be extremely lethal. Her potential attacks would probably be memory make magic in which the caster can manipulate memories as well as negate other magic using her own memory. It is some extremely dangerous magic http://fairytail.wikia.com/wiki/Memory-Make

Her weapon would be a card from RECOM.

 

Don't forget that game was a shared dream between Riku and Sora so I don't think it would count

 

Uh... so?
Joshua was real, along with the other TWEWY chracters

 

He was part of a dream so not real

 

no, that's not how it works at all

 

Then explain, and also explain how the girls from FF X-2 are fairys in KH2 and not the first game they come from, how Selphie is about 12/13 while Squall/Leon is in his 20s when they are closer to the same age in FF8. Just because he's an angel in TWEWY doesn't mean he is one in KH3D. Beside they world you meet them in is called a Dream World after all

 

While I can only restate the above points (angels aren't really a big part of KH's canon, she's probably a metaphorical angel, etc.), I do think that this is a pretty interesting theory, and now I'm curious as to whether or not all these similarities were intentional.

But Joshua tells Riku that

Spoiler

Shibuya was swallowed by darkness and he managed to find a dormant world where he could send Neku, Shiki, Beat and Rhyme to rescue them from their fates.

By your logic, none of the characters who appeared in sleeping worlds ever went through the events that Sora and Riku witnessed, but when we look at the whole story of Prankster's Paradise/Monstro, that argument is shattered completely. Apart from that, the last world in the game and the people who interact with a still sleeping Sora and Riku also prove that sleep =/= fake in 3D.

 

TWEWY delves into alternate realities in its secret ending. In KH3D Joshua explains that the rest of the TWEWY cameos were Erased by a Reaper in their own world, so he gathered up their fragments and took them to Traverse Town so they could be reborn.
As for how I know Joshua is still an angel in this version:

(10:06)
The girls from X-2 are alternate reality versions of the FF ones, who live at Radiant Garden Same applies to Leon and such. Why are their ages so different? Time works differently on different worlds.

 

Now if Hatok would have just said that then I wouldn't have said all that, since it's been a while since I played the game and I remember more of the end game then the start so eh

 

And there's a Genie in Agrabah. Doesn't mean they exist in the KH over-verse.

 

Considering agrabah was part of that over-verse, it does.
Or, to be specific, if one was introduced, there would be a precedent

 

But a hierarchy has also been established. Each of the worlds within Kingdom Hearts has its own laws, its own standards, its own conventions - which do not necessarily overlap with or translate to the universe at large. This is the most sensible way for a crossover to work, otherwise Sora and company could've just wished all of Xehanort's work undone and the plot would be over.

What we assume as true for one world does not necessarily hold true for all. Each Disney world observes its own mythos, its own distinct canon, and the KH crew are just visiting at best. Jumping into and out of a moving picture frame. The mythos by which Kingdom Hearts itself operates gives us no reason to believe angels can, should, or do exist. It would be disruptive, much like a fix-all Genie.

 

But there's a problem there. Agrabah's Genie CAN affect the outside world. In KH1 he specifically says he could bring Jasmine back. The reason Genie isn't put to more useful effect is because, like the movie, the writers act like only Aladin can use the Genie, completely ignoring Jasmine, and now Sora Donald and Goofy as well.

 

I didn't say Genie couldn't affect the outside world, I said his powers don't necessarily translate. Pay attention, sprout!

Genie, among others, clearly can interact with the world at large in Kingdom Hearts; but in his case, all of those charms, tricks, and cosmic powers become just another spell in Sora's arsenal. That's what it all amounts to.

 

But you're moving into gameplay now. This was originally about the possibility of there being a certain type of creature in KH, and I'd say as long as it exists somehwere in the KH-verse at large, there's precedent for one to show up elsewhere.

 

This is the thing people don't seem to understand about video games. The gameplay isn't just some cancerous growth in the underside of the story, it's part of it. They must align. A game where they don't is evaluably bad. If something within the story is contradicted by the gameplay, it frays our understanding of it, cheapens it. It becomes just a cute little thing we divert ourselves with between levels, a chance for our fingers to rest, and nothing more. One hasn't the right to be ignored in examining the other.

Every work of fiction has rules. A ceiling of plausibility. Breaching that ceiling causes disbelief to come out of suspension. You're trying to sell me angels? There is no precedent. The highest power in this world is Kingdom Hearts itself, and there's no reason to believe it has delineated any such thing as an angel to carry out its will, nor that they would exist by any other means. They exist symbolically, to be sure; a creature with such features appears as a Heartless in the first installment, and Naminé bears some superficial characteristics, as has been pointed out. But then, so do the Princesses of Heart. No reason to believe they're all angels too, so why Naminé?
