Two unicorn twins, Fortune Flicker and Lucky Luster, have been destined since birth to wield the Keyblade. After instructing the ponies in Canterlot Castle for fourteen years, and with a threat of Heartless yet to appear, Princess Celestia sends them to Ponyville to study magic under Twilight Sparkle, both to expand upon the twins' abilities and their experiences, and to introduce Twilight to the magic of teaching. But when an ancient villain appears, commanding an army of Heartless, will Fortune and Lucky be able to save Equestria - and the rest of the world - from descent into darkness?
If you're worrying that I'm going to break characters by introducing Kingdom Hearts characters into the pony universe, don't. There won't be any Kingdom Hearts characters in this story, except for the Heartless, and there won't be any traveling between worlds. Given the option, I wouldn't even even call it a proper crossover. It's more like the Kingdom Hearts mythology applied to the MLP universe.
It's a good start, yet it seems to be going a bit fast.

Whoo, my first story comment! Thanks for taking the time to read and comment.
I intentionally stated it this way; I didn't want to spend too much time in Canterlot. Once they get to Ponyville (chapter 3), the pace is going to slow down. More adventures around town, that sort of thing.
Two of my favourite things mashed up. You sir, are amazing.

Thanks! If you keep reading, I promise you won't be dissapointed.
If this is awful, I will hunt you down. Kingdom Hearts is my favorite video game series OF ALL TIME. If it's great, well, you'll know it by what I will say.
Also, will this be based off of any of the games? And will it be just Heartless, or also Nobodies and/or Unversed?

Kingdom Hearts is my favorite video game series as well, so no worries. I also write a bit (read: a crapload) of original fiction, so my writing style is fairly consistent.
To answer your questions: no, this won't be based off any of the games. In fact, I'm not going to be including any Disney or Square characters at all . It's just going to be the Heartless (no Nobodies or Unversed). The main reason is that I don't want to muddy the Kingdom Hearts universe; the timeline and sequence of events in that universe is MUCH less flexible than that of the ponyverse, where time doesn't seem to progress in any meaningful way (thus far, anyway).
That said, I'm considering a passing mention of someone like Yen Sid or Ansem the Wise by Celestia. That would be the extent of involvement from any KH characters.
I hope you continue reading and commenting as I continue updating!
681213 Thank you very much for letting me know. I'll start reading this very soon. :)
boring
680800Excellent, Although, May I ask your intent on the actual Nobodies and Heartless? Sometimes, thoroughly detailed action sequences can be a bit awkward unless you keep up the pace of them.

Well, I plan on having maybe one chapter that focuses on a fight with a mini-boss sort of Heartless (sort of as an introduction to how they fight with keyblades), and then the 'final boss' at the end. As for the rest of the encounters with the Heartless, I won't be describing them in any great detail.

May I ask why?
Excellent work. A bit sketchy at the beginning of Chapter 4, but it smoothed out.
700560
Thanks. Can I ask what was sketchy about it?
The bit about learning Fira, but it makes sense, so I approve.
Can't wait for another chapter.
737554 Thanks! Glad you like it.
I really like your story and being a KH fan I think your idea is very creative and fun to work with. I especially praise you for your dialog, to some it comes naturally, to others it's a thorn in your side. Yours, my friend, is perfection. I'll be eagerly waiting for your next chapter as well.
737955 Wow, such high praise! I really appreciate it.
681459 Let me know what you think when you do!
holy crap...... reminds me of the doors in Nightmare before Christmas.
I hope that near the end of this story someone or somepony would say this:
"The sister of Light and the brother of Darkness will meet again in a one final clash."
*reads door scene*
Oh snap...
Cannot wait to read more.

I've read KH/MLP cross-overs before, but this one feels a lot more original. The decision to esentially not inculde anything Disney or Square related really pays off.
931159 Thanks! I felt that including characters from outside the ponyverse would make it too trite and predictable. It may seem counter-intuitive, but I feel like I have a lot more freedom when only working with characters from one universe and including the mythology of another.
So how will Fortune and Lucky learn to summon and get a gummi ship ?
934843 They're not going to do either of those things.
934545 Exactly, that's what's so brilliant with this story.
935215 Well I can live with that.

So awesome. Although there was one error;
There, now that that's out of the way.
"He jumped to his hooves." Other than that, this was awesome.
Boss fight !
So happy to see some action.But now Fortune has to tell them everything.Story time !
935531 Ooh, nice catch, thanks.
im liking where this is going. and a side note can you actually run up the darksiders arm in the game cause i just kept hitting its hands
953152 Yeah, you can. That's the quickest way to beat him. I didn't realize it until you fight him again at the end.
*Sees update*

For a second, I thought the pandas were those bear nightmares from KH3D.
And when it hits, all Tartarus is going to break loose.
Awesome setup for something badass down the road. 
1108877 Good ol' Kooma Pandas. But no, I'm not going to have any Dream Eaters/Nobodies/Unversed in this story.
The reason I haven't updated in so long is because I've been busy studying for the MCAT. I'm glad someone's excited to see the new chapter, though.
finally some heartless to take on.
1110921 Ooh... You may have to wait a bit longer. I haven't totally decided which part of the story should come next.
lol ponies cant fight.
Maybe Lucky will be more "lucky" in fighting.

oh...
Get out of here Xehanort, you're drunk.
Ah, good old Orichalcum.
Lucky, run! Don't make the same mistake Riku did!
1468301 Ha.
But seriously, don't forget that there aren't any characters from KH canon in this story (besides the Heartless, obviously).
1467570 Is that a good 'oh' or a bad 'oh'?
I am just going to say this.
FOR PAANDARIIAA!!!
why do i think chrysalis says the last sentence
1468587 good
I'm gonna go ahead and call it: Lucky=same situation as Riku in KH1
My my... What could this all mean?
