1) Okay so emblem heartless are any heartless that were created by a means other than a person being consumed by their own darkness. Therefore since heartless stealing other peoples hearts and Xehanorts Heartless Manufactory are different methods of creating heartless they produce emblem heartless not purebloods. Is that correct? But wait a second If I recall Xehanort's first experience (after BBS) with a heartless, he describes it with yellow beady eyes and an antennae which is obviously a Shadow Heartless which is a pureblood heartless but Xehanort was the one who experimented on the test subject's heart causing it to collapse. Therefore shouldnt an emblem heartless have been created?
Not necessarily. Xehanort's initial experiments may have produced naturally occurring purebloods. This was his methodology as described in his Reports:
Extract the darkness from a person's heart. Cultivate darkness in a pure heart. Both suppress and amplify the darkness within.
Extracting the darkness from a person's Heart would not necessarily do anything, but it may create a pureblood,
possibly; more likely, it would simply cause the subject's Heart to shatter in the same way Ven's almost did in
Birth By Sleep. Cultivating darkness in a "pure" Heart would almost certainly create a pureblood; that's how purebloods are naturally born. It isn't until we reach his third method that we begin to enter an artificial practice in which he himself is manipulating the strength of darkness within people's Hearts and it's here that his work towards creating his own "strain" of Heartless begins.
Also can I just ask what actually happens when a heartless steals a heart? I mean does that heart that was stolen get consumed by darkness from the heartless that stole it which would make sense as that is how another heartless is formed and also what benefit does the original heartless that stole it get (do they transform into a stonger heartless or is just that they enjoy consuming hearts and what do they do with all the hearts they have stolen?)
You're mostly right. Heartless are simply sentient manifestations of darkness; they function in the same way darkness naturally does in any form, by spreading and consuming everything around them. A Heartless takes its form based on a Heart that has fallen to darkness (in the case of Emblems), or based on the darkness within a person's Heart (in the case of Purebloods); when a Heartless takes a Heart, that Heart falls to darkness and becomes a new Heartless. There isn't necessarily a "benefit" for the Heartless, per se: it's just instinct.
2) I know Xehanort used test subjects in his earliest experiments but that was before the Heartless Manufactory was created. Are you both saying that there are test subjects used in this machine and the machine just someone corrupts their heart with darkness? But what about during KH1 and KH2 there wouldn't have been anyone to gather test subjects and there would need to be a lot of test subjects. How could emblem heartless continue to come out from the machine if there was no one to gather hearts from? Though Ansem report 8 says "This may be a step toward creating a heart from nothing" I don't think the machine could actually create a heart. Also how could a machine corrupt a heart with darkness or it that something we just don't really know?
Actually, it's possible that the machine did create Hearts out of nothing (well, not nothing). The KH series has proven many times that Hearts (or at least the elements of them) can be fabricated. Xehanort, in particular, was invested heavily in research along these lines. The Emblem Heartless may well be formed from artificial Hearts, which would further separate them from Purebloods; this would also correlate with how Xemnas was building an artificial Kingdom Hearts-- formed from the artificial Hearts released from Emblems. As for your final question, darkness exists in every Heart (except pure Hearts of light, which only belong to the Princesses and possibly Ven). As I mentioned above, Xehanort was experimenting with both "cultivating" and amplifying the darkness within a Heart; and, as I already mentioned, darkness's very nature is to consume. In KH, Ansem SoD created a Keyblade from the Princesses of Hearts which unlocked the darkness in people's Hearts: depending on how they related to the darkness, that could either strengthen them (as in the case of Maleficent) or cause their Heart to collapse into darkness (as with Sora). This was the sum of his research, and the Heartless Manufactory likely worked based upon a similar premise.
3) With what I have learned in this topic I am now assuming that when any heartless (emblem or pureblood) takes a heart, it creates another emblem.
No, it would not necessarily create another Emblem. A Heart falling to darkness would still produce a Pureblood, because the Purebloods are formed from that darkness. Purebloods are still formed from the Heart: they're the pure darkness of a Heart that has succumbed to darkness. However, if an Emblem Heartless takes a Heart, then an Emblem Heartless would be formed. You could almost consider it a form of breeding, although it's a somewhat unsettling way to view it: Purebloods beget Purebloods, Emblems beget Emblems.
Also would I be right in saying that the trickmaster, parasite cage, behemoth etc. are people who had strong darkness in their hearts who had their hearts corrupted by darkness in a way other than themselves falling into darkness. Meaning that they weren't necessarily created by Xehanort's machine right?
You're right that they would be formed from Hearts with a great deal of darkness inside of them, but you're wrong that they would have been formed in any other way than from a Heart falling to darkness. In the case of strong Emblem Heartless, all that occurred was that Xehanort's machine happened to capture and/or create a Heart with a greater portion of darkness than light.
Also what about Xehanort's Heartless (though I know he is a special case unlike any other heartless) but Ansem SoD has an emblem on him however from what we know Xehanort and the other apprentices were consumed by their own darkness therefore shouldn't a pureblood heartless have been created.
Ansem SoD was a Pureblood (kind of...he was a very special Heartless in every way). The Emblem he wears is a brooch on his coat, not an actual part of his form. He most likely wears it to signify his control and/or creation of the Emblems. The other members of his research team probably did create Purebloods, although many of them were probably weaker Shadows and the like since most of them didn't have a great deal of darkness in their Hearts to begin with (Braig is almost definitely an exception to this, but even then, the form of his Heartless isn't important; Nomura has said as much himself).
Though the ending of the KH 3D TGS 2011 trailer suggests that maybe Xehanort and the others became heartless in a different way than we expect.
Well, there are a number of factors that have to be taken into consideration with the creation of a Heartless. The strength of the Heart's darkness and whether the Heart was forcibly corrupted or willingly succumbed are two of the most prominent, however, as I've said, the nature of the Organization's Heartless is not, according to Nomura, of any real relevance. Xehanort's Heartless is the only one who maintained a human form, both because of the immense strength of Apprentice Xehanort's darkness, the control he had over it, possibly the fact that his Heart is composed from those of three Keyblade Masters (Terra doesn't have the title, but his Heart is that strong) and the fact that he allowed the darkness to consume it deliberately.
I suppose, based on what you're saying, it is possible that the Organization members lost their Hearts in such a way that Emblems were created. It's not likely, but possible.
4) If Purebloods are just made of the darkness itself rather than the heart then what happens to the heart itself?
Sorry, I don't think I worded that well. As I've explained above, both Emblems and Purebloods are created from Hearts, but through different processes.
Also remember what Yen Sid said about a person being restored. He said that the heart taken by the heartless must destroyed. Point being that the pureblood heartless must release the heart. This is just a theory but maybe destroying a pureblood heartless just destroys the darkness and restores the heart which goes to the place where hearts stay without a body (just like where riku was in the KH1 FM cutscene where he talked to Mickey) until its body is released (if there was a nobody). What do you think? My theory might actually link to your second point because if by destroying a pureblood heartless it restores the heart (be removing the darkness) then it can't be obtained but stolen hearts can still be gathered which are from emblem heartless.
Yes, the whole matter regarding Purebloods and Hearts is something of a sticky situation. I don't necessarily think the Heart and its darkness are separated, although that's possible. I have no immediate answers here.
Umm I just thought of this now but pureblood heartless can steal hearts too right so even if you can't get the original why couldnt Xemnas get his hands on the hearts stolen by purebloods? (Maybe this was explained in 358/2 Days but I can't remember)
This is also a question of the nature of the Keyblade. In order for a Heart to be collected as part of Xemnas's Kingdom Hearts, it has to be released by the Keyblade. Because Purebloods are naturally occurring based on the innate darkness in every Heart, perhaps the Keyblade doesn't release the Hearts from them in that way; perhaps the Heart from a Pureblood is naturally redirected to a place where the Body and Soul can meet it in order to reform a complete person. That would beg the question as to whether or not Hearts formed into Emblems can create Nobodies, and whether Xemnas was interrupting the process of a Somebody being reborn with every Heart he stole. It seems sort of unlikely, but considering his Kingdom Hearts was artificial, there are all kinds of discrepancies that have to be taken into account.
