* There's a good reason why the Fairy Godmother won't allow Aqua to assassinate the Tremaine family: [[spoiler: Aqua plans to use light to fight them, who are confirmed to be the closest we'd ever get besides Vanitas to have hearts of pure darkness. So if she clashes with them, then she would end up recreating the χ-blade very early on]]. The Fairy Godmother knew about this, and, [[spoiler: not wanting a Keyblade War in her home world]], told Aqua to stop before she even begins. It's not just the major characters who'd know this horrible knowledge, as the Fairy Godmother (and King Triton) seem to know, too.

** Actually, it's even more complex than that: In KH Universe, a being is made up of Heart, Body and Soul/Mind. It roughly corresponds to the japanese concepts of "Kokoro-Karada-Tamashi". Xemnas is made up of Terra's body and MX's mind/soul. Where is Terra's mind/soul, you ask? Lingering Sentiment. 'Nuff said.

** Their fate remains ambitious, but what if the trio didn't go to {{Hell}} ([[MoralEventHorizon where they belong]])? The Castle of Dreams is one of the first known worlds destroyed (alongside Radiant Garden and, possibly, Space Paranoids), as the Final Mix version reveals. And it's confirmed that the Heartless existed before the Unversed, and it's possible for one to be turned into a Pureblood. That's right: Lady Tremaine, Drizella and Anastasia didn't perish; they were ''turned into Heartless'', and [[{{Revenge}} captured Cinderella]] and [[OmnicidalManiac intentionally destroyed their world (and then possibly millions of others)]] as payback! Bonus points if they became Darksides. More bonus points if they were the Darksides Sora fought in the first game (as one destroyed ''his'' world)!

*** This is mostly correct, with the major exception that [[SinisterScimitar Soul]] [[CoolSword Eater]] is ''not'' a Keyblade.[[note]]Unless you're referring to the fact that he stills calls his Way to the Dawn "Soul Eater" in Kingdom Hearts II, in which case ignore the rest of this post.[[/note]] It's originally a dark [[HeroesPreferSwords sword]] that Riku [[WeaponOfChoice learns to manifest]] to compensate for his ''lack'' of a Keyblade. And Riku does ''not actually have the making'' in Kingdom Hearts I, as he lets himself get taken by darkness like the rest of Destiny Islands, which is why the Keyblade he was supposed to manifest actually went to Sora instead. He's able to steal it back temporarily when his heart is strengthened by his determination to protect Kairi, but Sora's more numerous connections with others' hearts wins out in the end, leaving Riku unworthy once again. It's not until the end of Kingdom Hearts II, ''three whole games'' worth of events later, that his Soul Eater [[EvolvingWeapon becomes a proper Keyblade]]. What has he been doing for those three games? Trying his damnedest to do right by his friends. Terra's promise still comes true, but the fact that Way to the Dawn is ''not'' the Keyblade that said promise had originally manifested (which is still in Sora's hands to this day[[note]]though some would argue that Sora conjured it on his own or had Ventus's help[[/note]]) and is instead an embodiment of Riku's character arc itself makes it even more of a Fridge Tearjerker when he finally manifests it.

* Been on my mind since the game's Japanese release, but what if Lady Tremaine and her daughters actually succeeded in harming, or worse, killing Cinderella? Considering that she's a Princess of Heart, and the trio's hearts are now 100% darkness, this clash could've ended up creating the χ-Blade very early on, even though Cindy didn't fight back, nor did any of them weald Keyblades (though Aqua was present). Chances are unlikely, though, but there's still a chance. Not only that, Cindy's murder would've resulted in unspeakable chaos (unless her pure heart reincarnated into another girl). Who knows what would've happened if it were not for Aqua...

*** Now that's a KH and female equitant of [[Franchise/JakAndDaxter Cyber Errol]].

* In an interesting case of [[spoiler: RealLifeRelative]] as well, apparently, using AkioOhtsuka as Xehanort all this time was leading up to [[spoiler:Creator/ChikaoOhtsuka (Akio's father) as Master Xehanort all for the sake of an age-affected variant of VoicesAreMental when he commits GrandTheftMe on Terra]].

* Hey guys, think about this ''awesome'' piece of FridgeBrilliance. The VeryDefinitelyFinalDungeon of the [[VideoGame/KingdomHearts first game]], End Of The World, had some parts of Snow White's, Cinderella's and Sleeping Beauty's worlds, that by now we know as Dwarf Woodlands, Castle of Dreams and Enchanted Dominion respectively. These three worlds are all next to each other, ''and'' next to Mirage Arena, where the teleport that links the save point with the main room works pretty much like the so-called "prison of the worlds" in End Of The World. This may lead us to think that Mirage Arena, Dwarf Woodlands, Castle of Dreams and Enchanted Dominion actually ''are'' End Of The World as it was in the beginning, since it's pretty much a chaotic mash-up of them. Now stop for a moment to think about one of the closest worlds to this mash-up: the fact that Radiant Garden was next to the then-future End Of The World creates a striking parallel with the fact that Hollow Bastion was also next to it in the first game, making the left half of the Birth By Sleep world map the past of the right half of the Kingdom Hearts world map, while the ''other'' world next to the then-future End Of The World is the world which became Castle Oblivion, that is ''the place Sora went to right after his visit to End Of The World'']], thus happening between the first KH and VideoGame/KingdomHeartsChainOfMemories. '''[[TheDevTeamThinksOfEverything Wow.]]'''

*** As [[Tropers/AlexSora89 I]] said in this WallOfText-like FridgeBrilliance, it's like the world map of ''BBS'' literally mirrors the one from the first game. Disney Castle and Olympus Colosseum were in the left edge of the world map in the first game. ''BBS'' places them in the right edge. ''[[TheDevTeamThinksOfEverything And once again... the Fridge Brilliance WORKS.]]''

* This game turned being a Keyblade bearer into something that anyone with a strong heart can do as opposed to a skill only Sora possessed. But if you think about it this makes Sora the "last survivor of an ancient warrior culture which aligns itself to light and opposes darkness". Considering that the English dub got MarkHamill as a voice actor, is Sora a reference to [[StarWars Luke '''Sky'''walker.]]

** Alternatively, consider this: Aqua was about to charge into the Tremaine household with the full intention of harming (and possibly ''killing'') three people who, horribleness towards Cinderella aside, really haven't done anything. The Fairy Godmother might have intervened not just to help Cinderella, but to prevent Aqua from turning into a KnightTemplar. Her sending Aqua to help Jaq could've been her way of showing Aqua that there are other ways of protecting the light aside from the heavy-handed "destroy the darkness" approach favored by Eraqus, and her speech about light and darkness going hand-in-hand could have been her way of telling Aqua that [[HeWhoFightsMonsters her dedication to protecting the Realm of Light could consume her like it did Eraqus if she takes it too far]].

The Fairy Godmother might have intervened to prevent Aqua from [[HeWhoFightsMonsters turning into a]] KnightTemplar by having her help Jac, turning her attentions from "destoy the darkness" to "help out people in need".

* In the case of Zack being from Olympus, it's more or less a ContinuityNod towards CrisisCore. Just before the first mission, Zack says that he wants to be a hero, and given that Young Herc is there as a hero-in-training, it starts to make sense.

** One word, Mana. While Sora MAY have stronger spells, his fighting style is not as refined. It's similar to how Xehanort can destroy a whole world with one move in a cutscene but he never uses it in a fight. why? It's Awesome but impractical to throw around. Which is probably why Sora ran out of mana in the first place, he was throwing everything he had. But then again, he IS the Hero.

* Considering that the purpose of Keyblade Wielders is to go to the innumerable worlds to protect them from the darkness and evil, many of those worlds being dark and evil looking but perfectly fine like Halloween Town for instance as well as the opposite, it makes sense that Terra, Aqua, and Ventus would have had "don't judge a book by it's cover" very very insistently hammered into them during their entire training. Therefore it's actually FridgeBrilliance that Terra trusts most of the villains right off (which is actually really blown out of proportion by the fandom) when they're ObviouslyEvil, they aren't to HIM because he's been raised not to judge people by what they look like, and unlike the viewers doesn't have the foreknowledge to know these people are evil. Terra isn't an idiot, he's simply unlucky enough to be manipulated by villains including Master Xehanort that haven't actually done anything evil yet when he interacts with them until the very end if ever, while the other 2 are fortunate enough to run into these villains when they have heard of or witnessed them actually doing something evil and thus they "appear" smarter when they would have done the exact same thing if their situation and Terra's were reversed.
* Aqua turning the Land of Departure into Castle Oblivion explains the gameplay changes between it and elsewhere in the series. It was something done to protect the land and Ventus from exploitation by Xehanort and other intruders, and as the creator Aqua herself probably doesn't have to deal with the annoying card system to fight while any foreigners would have to, allowing her to fight any intruders at full strength while everyone else would have to be significantly gimped by the card system. This also explains why despite supposedly being the Lord of the Castle even Marluxia has to deal with the limitations of the card system, despite {[TheComputerIsACheatingBastard having found a few workarounds for it,]] he's not REALLY the Lord of the Castle.

* This troper [[@/AlexSora89 (still me, guys)]] just had a relatively minor realization. Why the FieldOfBlades that is [[TheVeryDefinitelyFinalDungeon Keyblade]] [[SceneryGorn Graveyard]] has many keyblades from ''VideoGame/KingdomHeartsII'' (like the [[PiratesOfTheCaribbean Follow The Wind]] or the [[VideoGame/FinalFantasyVII Fenrir]], just to name two) and from the first KH? CallForward? No, it's just that those worlds were still existing, and they never got caught in the darkness.

* Abit of FridgeHorror, HarsherInHindsight and Foreshadowing. Take note in the beginning how Aqua's holding the Wayfinders. She has Terra's and Ven's together in one hand with hers alone in the other. [[spoiler: She ends up alone in the end, stranded in the Realm of Darkness, with Ven and Terra both lost in Castle Oblivion and to Xehanort respectively.]]

** During Birth by Sleep, Ventus met Peter Pan - Peter Pan never shows up in ''Days'' at all. Peter Pan would most ''definitely'' recognize Roxas as "Ven", and unlike Tinker Bell would be able to spoil crucial details to the audience. Puts a whole new perspective on Neverland's involvement, doesn't it?

** ChainOfMemories also makes sense from this explanation. Sora, being so close to Ventus's body, ended up unlocking some of Ven's skills. Thus letting him do crazy stuff that he hasn't been able to do before!
