So it's fair to say that Marluxia ranks very high on my list of favourite Organization XIII members, butting heads with Axel in the No. II spot. I have a theory about how his return may happen in Kingdom Hearts III.

 

Now the base of this theory is completely based on the belief that his essence did not escape the room of the final battle of Re: Chain of Memories after his death at the hands of Sora.

 

I believe that he still exists within that room and someone, whether it be Mickey, Riku, Aqua, Sora, whoever, will trigger his reincarnation, if you will, by opening the door, whether this would be before they find Ventus, or after the find Ventus, I honestly don't know, but it would sort of be like... How Terra's Lingering Will trapped Terranort in that, somewhat of a bubble at the end of Birth By Sleep as the final battle in Terra's story. 

 

After this, Marluxia will realize that the Organization were not who he thought they were as they did not send aid to help him, but sent Axel to kill him. I think that this would, in turn, make Marluxia a kind of chaotic neutral character, he still has a grudge against Sora for killing his Nobody but would have a grudge against the Organization for stabbing him in the back.  

 

The other theory is that this essence would not exist and, like other Nobodies, he would return to his somebody. Who that somebody is is very up in the air, maybe he could return with the likes of Larxene, Demyx and Luxord, however with the die chess piece in the KHIII E3 2015 trailer leads me to assume that this is in some way connected to Luxord as Luxord was the gambler of the Organization, with die heavily symbolizing that. We don't know what world he came from, he couldn't have come from Radiant Garden as he was not with the Radiant Garden members -Braig, Lea, Isa, Dilan, Even, Ienzo- in Birth by Sleep. So what I believe is albeit a shot in the dark, but could it be possible that Marluxia originally resided in Daybreak Town or Cable Town? We know that Cable Town is pretty much confirmed at this point, but Daybreak Town is a possibility as a 3D version of it is being made for Kingdom Hearts X -Back Cover- which just so happens to use the same graphical engine as Kingdom Hearts III.

 

So could we see a return of Daybreak Town? Will we see the return of Marluxia? Let me know your thoughts and opinions, let's get a discussion going in the comments below.

You just wanted to see Kairi have a bad reaction to scythes and/or rose petals.

 

Although if an ghostly illusion of Namine were to appear, she might warn Kairi not to trust him. And maybe avoid telling him that she's got Namine inside of her.

I don't think so. Marluxia could have been there in KH3D when Sora was going to become a Xehanort. He could have been used to help get rid of those who did not fit the conditions to become a Xehanort. He could have merely done what all the other Xehanorts did: time travel and be one of those who did not take off their hood.

 

Cable Town has not been confirmed. I don't know where you got that, but Cable Town hasn't been confirmed. As for Luxord, Demyx, and Larxene, we may see them again, but where and when we have yet to see. You lost me at the half way point of the theory, but I managed to understand everything else.

Edited January 24, 20169 yr by KingdomHearts3

Nobodies reincarnate in the location their original self expired. Unless Marluxia is a special nobody with unusual consequences he probably won't resurrect at Castle Oblivion seeing as how the castle is impossible to navigate and his somebody likely met his end somewhere else. 

 

If Marluxia is in fact an exception, and he reincarnates in Castle Oblivion I have my doubts that he would feel betrayed by the Organization seeing as how he was the traitor in the scenario. That being said he still shouldn't need to feel any loyalty to the organization, and he probably won't be too happy with Sora, so a neutral route fits him quite well actually. It's even in character as Marluxia, being the egomaniac that he is, cares about no one but himself so he shouldn't have any real ties with anyone.

 

I think Marluxia will only be loyal to himself (lol) no matter where he's regenerated and who really knows where that'll be ¯_(ツ)_/¯

I thought that Marluxia was still in that room, and maybe that's how it was originaly, but in Re: CoM you see him vanish.

 

 

Marluxia will hopefully be one of the new Organization Members, and if he isn't, he'll probably return anyways (we'll hopefully see all somebodies).

I don't think so. Marluxia could have been there in KH3D when Sora was going to become a Xehanort. He could have been used to help get rid of those who did not fit the conditions to become a Xehanort. He could have merely done what all the other Xehanorts did: time travel and be one of those who did not take off their hood.

I very much doubt it. Xemnas dispatched Axel to kill off Larxene, Marluxia, Zexion, Lexaeus and Vexen as they were all seen as traitorous by plotting to use Sora to their own devices.

 

 

Cable Town has not been confirmed. I don't know where you got that, but Cable Town hasn't been confirmed.

Cable Town was pretty much confirmed a while ago. Back at the 2.5 Launch Event, many many people were giving information about the trailer we, as the public, did not get to see. One of these pieces of information was a new Keyblade being revealed, and lo and behold, the exact same Keyblade as the one from the 2.5 event that Zephyr conceptualized was revealed, with the exact same Keyblade transformations and an albeit, slightly more colourful palette. Cable Town was a part of this 2.5 event and Zephyr also conceptualized what was shown for this "Cable Town" and again, lo and behold, the room that was a part of Cable Town was revealed as the place where Young Xehanort and Young Eraqus have their important and influential conversation about the Keyblade War and the Lost Masters. You can take it with a grain of salt but Zephyr has been correct twice already. So it's clear to see he knows what he's talking about.

I very much doubt it. Xemnas dispatched Axel to kill off Larxene, Marluxia, Zexion, Lexaeus and Vexen as they were all seen as traitorous by plotting to use Sora to their own devices.

Xemnas didn't know who the traitors were, he sent Axel and the posible traitors to CO, so it was Axel's job to find it who they were, and mind you it was only Marluxia and Larxene. Vexen had to die in order to find out a bit more of Marluxia, Lexaeus was killed by Riku, which wasn't part of any plan, and Zexion was only killed because he could take Saïx's place in the Organization, so Axel killed him as a favour, basically .

I very much doubt it. Xemnas dispatched Axel to kill off Larxene, Marluxia, Zexion, Lexaeus and Vexen as they were all seen as traitorous by plotting to use Sora to their own devices.

Yes he did use Axel to destroy them, but do you think he would not have Marluxia set it up to make it look like those that went to Castle Oblivion were traitors? If Xemnas were to have Axel destroy them for no reason, then that would make everyone who did not go question him and possibly turn against him leaving him with no vessels to bear Master Xehanort's heart. He wanted Marluxia to help weed out those who did not fit the mark.

That Cable Town they showed was stuff the team worked on. It was all placeholder stuff. The conversation between Eraqus and Xehanort has not been confirmed to be in Cable Town. If anywhere, they would be in the Land of Departure. Besides, Zephyr is not an employee of SQEX. Unless it came from Nomura or SQEX at all, it is to be taken with a grain of salt. Now the Keyblade that he saw could have been a concept before we get what we saw at E3 2015. If what you say is true, then provide a quote from an interview with Nomura and a link.

If Xehanort wanted Sora to be a 13th vessel then Marluxia is not out of the question at all!

If Xehanort wanted Sora to be a 13th vessel then Marluxia is not out of the question at all!

I'd have to agree. I feel like Marluxia's biggest obstacle in becoming a vessel is his own narcissism, not his betrayal. 

 

Marluxia is definitely a possible seeker especially given his own power hungry ways. That being said he's not confirmed or anything, but he's got a shot for sure.

Okay. I'll provide evidence that the Keyblade is about 98% the EXACT same as the one Zephyr conceptualized. And that the room that was conceptualized as part of "Cable Town" by Zephyr is the exact same as the room in the E3 Trailer.

 

Here is the concept of the room made by Zephyr:

 

And here is a picture of the room, with the chess pieces and curtains, as well as the window and even the table being about 98% the same.

 

 

Now. Here is the Keyblade and its transformations, conceptualized by Zephyr.

 

 

And here are multiple pictures and gifs of the Keyblade and its transformations in the E3 trailer, again, about 98% the same.

Edited January 24, 20169 yr by AzureAce

Marluxia would return as a human if his heartless was destroyed just like his nobody was in CO. He would revive exactly where he lost his heart not where his nobody died. As for his essence in CO i really do not think there is much more to that but Sora "just locking the keyhole" even if not making any sense lol. He did not understand what nobodies were and how they worked so he was prolly just covering his bases. We really do not know more than that regarding that subject. I don't think it's the exact same thing as LW. Even so, Terra's LW is Terra's thoughts trapped in armor - not his heart or nobody so he won't need his LW to revive per se. He just needed his nobody and heartless destroyed. Even then his situation is the exception and special as we all know.

 

Marluxia could return as human or could have been brought back from the past via time travel. Either is viable. Things to mention though:

 

Marluxia and Larxene were the traitors not Vexen, Lexaeus, or Zexion. Vexen was killed to prove a fake loyalty to Marluxia and gain his trust and Axel regretted doing that. Zexion was killed for two reasons- he knew too much as stated by Axel in game and he also stood in the way of Saix and his rise up the org ladder of authority. Lexaeus was killed by Riku. Xemnas did know who were traitors and who were not. He even knew Axel and Saix were traitors. They all had their purposes to serve with him.

 

In DDD Xemnas states being a traitor/lack of trust supposedly disqualifies you as a proper vessel yet we knew Saix was a traitor and planning against the org and he still unknowingly became a vessel for Xehanort. I find this contradictive.

 

 

Nomura: It is a fact that Saix and Axel probably wanted to take over the Organization, however they didn�t understand what they were going to do or how to do it. As for Xemnas, he knew about this betrayal, but never brought it up. Generally, one�s conduct was for the sake of their purpose. 

 

 

Day 71: The Traitors' End Author: Xigbar Saïx had a hand in what went down at Castle Oblivion - well, more like a whole arm. Which means Axel was in on it as well. It's a fact that Xemnas ordered Axel to take out the traitors, orders which went through Saïx. No specific names were given, but naturally Xemnas knew who the turncoats were right from the get-go.

 

Day 24: The Upper Floors

• Author: Zexion

Marluxia has succeeded in leading the Keyblade master to the castle.
I sense multiple threads at work, but details on each of the projects are scarce. I suspect some alleged organization projects are secretly private machinations.
Marluxia seems especially suspect.

Day 25: Hollow Ties

• Author: Lexaeus

Pressing Zexion for answers would be a waste of time. I know that, but this dearth of information is hard to accept. What’s happening on the upper levels? What ought we be doing down here? They hug their truths close and leave the rest to speculate.
Zexion talks of the bond we share as an Organization, but how could such a thing exist? Still, he remains the only one I can trust.

Day 26: Axel’s Actions

• Author: Zexion

Simple deduction suggests Axel’s outwardly inscrutable actions are the result of some directive from Saïx.
Why else eliminate Vexen? He simply wanted to do research. Did we not all stand to gain from the fruits of his Program? What is Axel thinking?

Day 27: Organization Dog

• Author: Marluxia

Axel is in the way, though I don’t know if he’s aware of our plot.
Vexen had no part in our plans–why eliminate him, assuming Axel’s orders were to root out traitors to the organization? Discerning his motives merits our full attention.

Day 28: Dealing with the Traitors

• Author: Axel

I’ve uncovered most of what I need to know about the Replica Program, but where’s the other one? I can’t find any trace of it.
…Vexen was caught in the middle. Pitiable, but unavoidable. I could not risk his Program falling into their hands.
Of greater concern are the traitors. Not the obvious turncoats, but the ones who will get in his and my way. The Keyblade master is not our enemy.

Day 72: Human

• Author: Axel

The longer you know someone, the less you need to speak in clear terms. Everything gets across with a wink and a nudge, a little reading between the lines…
When it comes to what befell our late comrades at Castle Oblivion, ambiguity suits me just fine.
But the Keyblade master and Roxas come out and say every little thing that comes to mind. Maybe that’s human, or maybe they’re just special.

Okay. I'll provide evidence that the Keyblade is about 98% the EXACT same as the one Zephyr conceptualized. And that the room that was conceptualized as part of "Cable Town" by Zephyr is the exact same as the room in the E3 Trailer.

Okay. What Nomura showed at the event was something new as he said. He did say it was too early to show worlds. With that being said, they had to show stuff in place of the official content. As for the other things, yes they look similar in some ways. The windows in the artist rendering look not much to not at all like the window in the E3 trailer. They aren't "98%" close to each other. The room Sora is in in the rendering is completely different than the room Xehanort and Eraqus are in too. They aren't even in a library which is what Sora is in as shown in the rendering. The keyblades have similarities in shape. Obviously the colors are different.

Yeah no as much as I like Marly and hope he gets some more depth or does his own thing, he's probably just going to be one of Master Xehanort's vessels that we didn't get to see in DDD seeing how he along with Luxord, Demyx and Larxene are still missing as of now.

 

The sudden appearance of his Nobody class showing up in the KHIII trailer may also help this out some more along with Nomura stating last month that he wants to work on developing enemies based on certain characters to show they've been to that world. kinda like KHII did with the specific nobodies of the remaining Org XIII ..............why? 

 

It was surprising to see the return of Nobodies in the recent Kingdom Hearts 3 footage. What sort of role will they play in the game? Can we expect to see any more enemy types besides Nobodies and Heartless?

 

Nomura: I want to make it so that you can tell who had come to that world by the enemies that appear there. I am thinking of the enemy types as a part of the total production this time.

 

The new Kingdom Hearts III trailer featured a new Nobody design with a scythe and flower petals, is this particular Nobody alluding to a certain former Organization member?

 

Nomura: I think that it’s easy to imagine but I do believe that it will appear in promotional materials sooner or later so please wait for that.

 

 

 

He has no real reason to do this unless he was hinting on something and seeing how we have the Organization back and running around just like in KHII...... 

 

 

Plus I know someone's gonna say "But Xemnas said he was a traitor so he can't be in it"

 

1. He never really said that. Just that those three categories of weakness of trust, body, will played a part in them not living to serve their purpose aka basically because of their actions, most of them got to survive right to the end where their KH was nearly completed. Plus Xemnas' qualifications don't have to match Xehanort's qualifications since the person coming back recompleted would give him a chance to go at them again. One shot of the Nort, and you get infected with your personality and actions not meaning much anymore. 

 

2. Saix says hi

 

3. Sora says hi also 

 

4. Terra says he's having a blast 

 

5. Marly is a greedy mothertrucker for power and the Keyblade..... just like Braig who's chilling with Xehanort. Marly didn't get along with Xemnas, who's to say he wouldn't get along with the old coot? Especially since the old coot would have something that Xemnas didn't have to offer: a way to wield his own Keyblade and path to power. You really think Marluxia would say no to all that? 

 

Now that we've established why Marly isn't really off the list for Norts especially with Nomura saying in the DDD ultimania that he and the other missing members could have been picked up like Braig and Isa, all that really prevents this is an outright confirmation. 

 

I personally want Marly to go eff things up as a rogue but I'm not allowed to have nice things so oh well

As I have already pointed out the traitors disqualification does not make sense bc of Saix alone. You cannot dispute lack of trust and what that implies and means. Xehanort should not be able to make any of them norts if they were traitors or planning against him according to this. He sent Axel to kill the traitors bc that would disqualify them and they were not useful to him anymore. However like I mentioned it's very contradictive and makes no sense considering Saix and all. If he was trying to take over them involuntarily he had to accomplish certain things like casting away their identity somehow and drowning them in darkness.

 

 As for Sora and Terra he tried to drown their hearts with darkness and rid them of their hearts and identity altogether so he wouldn't need their loyalty or trust voluntarily. He planned to rid Terra of his heart altogether when he took over and when he couldn't do that he had to try to consume and take over it altogether and then split himself. He also used his entire heart and not just a piece.

 

For Sora he had to drown his heart in darkness in a deep deep sleep he was not suppose to ever awake from so Xehanort could take over his body completely without issue. He almost succeeded until Sora was rescued. He resorted to diff routes due to past difficulties like Terra and such.

 

All that said, I do believe Marluxia can still be in the running somehow to be a vessel and we know for a fact he's coming back - it's been confirmed like you have mentioned. It's just a matter of how Nomura decides to write it xDDD

That's basically my point though. Xemnas' words don't really mean anything or it's just as simple as his words meaning something like this: the reason for them having the weakness of trust is why they couldn't live to fulfill their purpose of being Norts(as we have with most of the group being off'ed by the time Xemnas' KH is pretty much completed and suffered the consequences for these traits) you could literally interpret it in any way but as I already said, Saix being in the new Org XIII is enough to say that Xemnas' words must have been BS. But my overall point about Sora and Terra is that people have literally speculated in the past that Xehanort wouldn't want to use somebody who would go against his wishes.......him going after Terra in the past and apparently has hold of him even now along with him going after Sora is proof enough he doesn't give a damn what they think as long as they fulfill his "criterias". I know that he needed to make them succumb to darkness first but I'm just poking fun at the notion that people would think that people like Marly and Larxy would be "disqualified" just because they wouldn't support Xehanort's agenda.  I'm sure Riku and Roxas wouldn't be thrilled on working with him either and he tried to go after them as well.

 

Nomura just gonna make Marly the KHII Luxord/Demyx of the new group so your sweet words of comfort have no effect on me </3

Yeah I think we are pretty much on the same page. It's why I don't write them off as vessels either..

This made me laugh more than it should have muahahaha

Your theory is pretty good!  I liked the idea of the Keyblade Wielders finding his essence in the room where Sora defeated him, because that could prove interesting!

 

But in my honest opinion, I think that Marluxia trying to take over the Organization might have been just a charade, just an act, ya know?  A means to an end to draw Sora and Riku in so that Xemnas could determine whether or not Sora and Riku were worthy candidates for being Seekers Of Darkness.  My guess would be that they wanted to see if Sora had it in him to push forward in Castle Oblivion, to risk losing his memory, to see how far he'd go to save the ones he cares about.  Seeing how powerful he was, when he defeated Marluxia, I'm guessing that Xemnas deemed Sora a candidate, whereas Riku proved to be a dead end, since he was overcoming his darkness, therefore making him unlikely to be a candidate.

 

My point with all this?  Marluxia could have faked his death, to follow on the Organization's plan, and he, in turn, would have a place in Xehanort's true Organization, ya know?  I mean sure, there were traitors that wanted to overthrow the Organization, but he might have been "playing along", so to speak!  This is all just speculation, though!  But if he were to come back, I'd love it, because Marluxia is my favorite Organization member!

All of the Organisation XIII member's somebodies will return in KH3, some of them are obviously vessels for Xehanort.
