This theory was originally developed by derekscorner and revised last night. I delve into the theory a little bit myself and came up with something pretty incredible. Again, most of this theory is in credit to derekscorner. All I’ve done is branch it out a little more. You can read the original post along with what I came up with here.
Kingdom Hearts is never entirely clear on how it’s universe works. The only trustworthy information you can get is spoken by characters in cut scenes, usually rather vague and said with symbolism, or it’s hidden somewhere in the “Reports” you recover throughout all of the games.
Because of this, the game can constantly flex it’s rules to bring about more scenarios and fix discrepancies it might have had in the past. But assuming, with the release 1.5+2.5 for the PS4, all of those discrepancies were fixed and the game is official, theories about this game will now become all the more relevant. And sensible.
Most things in Kingdom Hearts can be explained away in a rather convoluted essay. However, there are still select few scenarios that fans can’t seem to tackle because it wouldn’t make sense for how the game’s universe operates. One of these leading scenarios is the issue of bringing the lost Nobodies back into existence. I’m talking about Roxas, Naminé, and Xion.
“But it’s easy!” You say with excitement. “Sora just needs to release their hearts and they’ll be here!”
Well, in a sense, you’re right. But it also wouldn’t make sense regarding how the game works. Not many people remember them because they weren’t really relevant until now, but the Secret Ansem reports obtained in Kingdom Hearts II describe how an individual being works:
Secret Ansem Report #4
Three elements combine to create a life: a heart, a soul, and a body. But what of the soul and body left behind when the heart is lost? When the soul leaves the body, its vessel, life gives way to death, but what about when the heart leaves? A being does not perish when its heart leaves its body. The heart alone disappears into the darkness.
The body is quite obviously the body of a person, which is just their vessel. Their heart is basically their personality and memories, as well as “power”, which is stored inside their body. And the soul is not really their spirit, but rather just the life-force or energy used to make a body living.
This is where things start to get confusing. Regarding Sora releasing the hearts of Roxas, Naminé, and Xion, it could only POTENTIALLY work for Roxas. It’s best if we explain what each character’s scenario is.
Roxas, even though he doesn’t look like Sora, nor even has his voice or personality, is still Sora’s Nobody. His creation was brought about by Sora’s sacrifice. Sora’s heart was cast into the darkness, reforming as a Heartless, whilst his body and soul reformed in the Realm Between as Roxas. Roxas had Ventus’ heart within him because Ven’s heart didn’t leave Sora’s body upon him stabbing himself with the Keyblade. Because of this, his body reformed to somewhat compare to Ventus. Though there still isn’t an explanation as to why his clothing isn’t identical. Maybe we’ll never know.
So Roxas was created from Sora’s body and soul and could only be recreated if Sora became a Heartless again, giving up his body and soul for Roxas’ possession.
Naminé is something different altogether, but somewhat similar in how she exists. She was created when Sora released Kairi’s heart from within him, but she doesn’t actually have the qualities of a Nobody that normally others do. Because Kairi has a heart of pure light, she literally can’t create a Heartless. When her heart was stolen, her body kinda just slumped over like a sleeping puppet, kinda like what happened to Ventus. But it’s the fact that her body DIDN’T reform as a Nobody, but stayed in the Realm of Light. What ACTUALLY created Naminé was Sora releasing her heart from within his body. This leads me and some others to believe a fraction of him went off to form Roxas while another to form Naminé. It also kinda adds up as to why Naminé has blonde hair, because Ventus’ heart influenced her appearance slightly. And why her appearance is so basic, because it’s not a real body whatsoever.
So Naminé doesn’t have any body or soul, but she was created from borrowed fragments of Sora’s and influenced by Sora and Ventus’ hearts.
Xion is a pretty straightforward one. She isn’t an actual Nobody, but a puppet that had a soul stuffed inside it. She also has memories of Kairi from when Vexen “tested” Sora in Chain of Memories. But because Sora’s memories of Kairi were being shadowed by Naminé, she appeared like a shadow of Kairi. Her entire existence is dependent on these memories remaining inside her body. But because she decided that Sora needs to awaken, she willingly gave them up to Roxas and her body perished without its fundamental core. And without that core, all memories built on top of it crashed down and the chain was destroyed, leading everyone to forget Xion ever existed. The links of her memories were buried in Sora’s heart.
So Xion’s entire existence was dependent on Sora’s memories of Kairi and without them, her body couldn’t stand. And because all of her memories are broken in Sora’s heart, she is woven into his being.
“But wait!” You say with confidence. “Sora returned to the Realm of Light without his body and soul when Kairi brought him back!”
And there you are, calling out the holes in the theory. Hate it when people do that. This is best explained by looking somewhere completely different in the series: the creation of Vanitas.
Oh yeah, our mean bean who wants to murder everyone and gave Haley Joel Osment the time of his life getting to laugh so deviously. Vanitas’ creation isn’t too hard to understand: when the darkness of Ventus’ heart got ripped out of his body, it reformed as a being of darkness, Vanitas. And this is the cool part: Vanitas DIDN’T use Ventus’ body to form himself, but rather the power of darkness itself. He created his body through sheer force of manipulating the darkness within him, or perhaps Xehanort did it. My point still stands either way: if a being of pure darkness is capable of creating a body of pure darkness, could a being of pure light create a body of pure light?
Yes, you heard me. Kairi didn’t bring Sora’s body back from the Realm Between, but rather made him a new one out of the light within her heart. This did, however, make Sora an incomplete person. Because he no longer had a real body, I would think his life would be more on the line than ever. He is literally a floating heart surrounded by light at this point, making Darkness all the more lethal to the boy. But that’s not too important right now.
Because it’s dangerous for Sora to just be a heart surrounded by light, especially with Xehanort still trying to turn him into a vessel, him just giving up his body for Roxas would be rather dangerous. Even if Kairi pulled him back from the darkness, there’s no guarantee the same thing would happen again. And you can’t repeat the actions for Naminé without somehow hurting Kairi in the process.
So our issue here is lack of body and soul. Roxas can’t just take Sora’s body again, it would leave Sora in harm’s way. Naminé being created out of fragments of a body, or even just sheer nothingness, won’t work again. And recreating Xion would require that they know where this puppet lab is and how everything there works.
Each of these situations, each person is under special circumstances. But there has always been one definite and constant thing that has been able to manifest itself in the real world without harm: the data used in Ansem’s computer.
Yeah. Data. Just the 1’s and 0’s. Need an example?
1) The munny pouch that belonged to data-Olette in Twilight Town. Riku was able to retrieve it from within the data-world and BRING IT INTO THE REAL WORLD. He handed it off to Mickey, who gave it to Sora for them to buy train tickets.
See, that always bugged me. Really badly. That train we just took is a MAGIC TRAIN that’s ONLY HERE FOR US. Why in the world would we need to pay for tickets to go on this train that Yen Sid sent for US? There’s no one on the train checking for tickets! YOU CAN TELL BECAUSE THEY JUST WALK RIGHT ON WITHOUT ARGUMENT. There wasn’t any reason for that munny pouch to be handed off to Sora unless they wanted to make it BLATANTLY OBVIOUS that DATA CAN BE BROUGHT INTO THE REAL WORLD.
2) The Heartless invasion by the MCP. This one is the less obvious, but complete giveaway. Those Heartless used during the invasion were, quite obviously, not meant to be in Radiant Garden. The MCP was spawning them there using data.
Yes! He used data to spawn the Heartless. Their models and code already existed in the computer, so he just turned on the Heartless Manufactory and went to work. And also, THE HEARTLESS MANUFACTORY! It literally CREATES BEINGS FROM DATA! This is a dead giveaway that data can be used to CREATE REAL LIFE THINGS!
And in Dream Drop Distance on the Grid, it’s constantly hinted at the fact that the device used to bring Sora and company in and out of Space Paranoids can work BOTH WAYS! In the actual movie, IT HAPPENED! A data person was brought out of the Grid and into the real world!
Data can be made into real, physical objects. And evidenced by the ending to Tron:Legacy, they can be alive, as well.
Now, how can I truly persuade you that this theory is correct? I was pondering this for a long time. While I first read about it, I was thinking to myself that this is completely bizarre and there’s no way the games would go this route. But as I looked into things myself and stared at the wall of Kingdom Hearts theories I’ve had over the years, it clicked. This was meant to happen. Allow me to explain.
The data version of Ansem and his research that was discovered inside Sora’s heart. This is huge. It seemed like a random thing that Nomura and crew threw into the game because… reasons. But it’s not. What if I told you that this data Riku found was actually research about how data can be brought into the real world and, in turn, can be used to recreate a person?
Ansem was researching the Nobodies and must’ve discovered something about using the data to make bodies for them. He must’ve told Naminé to some degree about this, giving her hope that she and Roxas wouldn’t actually disappear. This is what leads to Coded (Kingdom Hearts Re:Coded).
“WHAT?! CODED?!” Yeah, I know! Coded is ACTUALLY RELEVANT? Incredible! Anyways, it starts like this:
Naminé placed a data version of herself, as well as the memories inside Sora’s heart, in the journal. Because these weren’t supposed to be here, the journal got all messed up. After repairing it, Data-Riku was able to find this hidden data and Data-Sora was sent to investigate. He found the hidden memories as well as Naminé telling him that Sora needs to call these memories to the surface in order to awaken their hearts. From their, the Keyblade to Return Hearts, as mentioned in previous games, would be used to extract their hearts from within Sora and return them to existence.
“Okay, cool. So Coded is hardly relevant.” OH, BUT I’M NOT DONE! Coded gets way more important. It’s actually the fundamental base for this part of the theory. And it’s mind-blowing how well this fits into place!
I’m gonna break away and give you guys a little lesson on 3D printing. In order to actually 3D print you need something that can fabricate what you’re trying to print. Once you have the device, you need a model. A good example of a model is like a ring. That ring was initially created or scanned into a model file so that the printer would be able to create it. You essentially make something out of data. So I’ve been thinking…
The transfer device in Ansem’s lab is basically a 3D printer, but it works both ways. It’s for someone to enter or exit the data-world. It’s MEANT to transfer atoms to data and data to atoms. It’s how they’re going to fabricate the bodies of data for Roxas, Naminé and Xion. It doesn’t even matter if you’re thinking of the lab in Twilight Town or the lab in Radiant Garden, because BOTH were built by Ansem!
But then comes the issue of the model they must “print” out. We need to create models of each of our little Nobodies from scratch. Huh? “Use Ventus as a model for Roxas?” Haha, well, you’re onto something. I’d completely agree with you to use Ventus as a basic model for Roxas were it not for the fact that we already HAVE a model of Roxas that’s already been created. The same can be said for Xion and Naminé. We have them already.
The models are already present in the journal in Coded.
Don’t believe me? Well, take a second glance at the Re:Coded HD Remaster from 2.5!
HE’S THERE! Roxas already has a FULL MODEL of his body in the journal, complete with voice and body build, as well as his face and his hair, as seen underneath the hood. All you need to do is drop his heart into it and export the data using the terminal in Ansem’s lab!
Naminé PLACED all of this data inside the journal, not just for Mickey and company to find it and inform Sora about the memories inside him, but so they could USE the data to CREATE BODIES FOR OUR LOST FRIENDS.
“Wait a second! This is really cool and all, but wouldn’t Ansem’s computer already have some of this data then, effectively making Coded useless again?”
Man, we all really hate Coded, don’t we? My answer to that is: no, Ansem’s computer wouldn’t have this information on it nor would the models exist there. Why? Because, as BLATANTLY SPOKEN by Ansem and Riku themselves, and clearly evidenced multiple times throughout the beginning of Kingdom Hearts II, their data-Twilight Town has been completely compromised. Nobodies are everywhere and searching for Roxas. If the Organization found any of this information that Ansem and Naminé had discovered, everything would be over. So, in a panic, Ansem wiped his computer of anything having to do with data in correlation to Nobodies and hid it inside Sora, hoping they would find it. Naminé would hide the information about Sora’s hidden memories and the models that could be used inside the journal to be discovered later. Because Naminé was taken somewhere safe by Axel, she never got the chance to tell Sora about it. And seeing how Ansem immediately felt the need to begin his revenge scheme against Xehanort, he just left the boy to his own devices.
Seeing the main plot of Coded be revealed with Castle Oblivion in the end, I have no doubts that this theory is correct. The focus of the game is to figure out what Naminé hid in the journal. I feel like data-Roxas’ role in the journal is important here. He was meant to get Sora to understand the painful memories inside him and that it was Sora’s role to wake them up and return them to existence. I’m still not entirely sure how he can tie into this theory, but I know he’s a strong point of it.
But in short, here’s what we came up with:
Data can be used to recreate bodies for the Nobodies who disappeared.
The data transfer device in Ansem’s lab can be used to fabricate these bodies.
The journal informs Sora on how to wake up the hearts inside him.
The journal holds the models required to fabricate the bodies.
