Comments to some of the quotes in there (much thanks, Jag, BTW!). Lemme do this one first, so these'll be a bit out of order:

Q) Firstly, you defined the intrinsic ability of Matoran of Iron (how they manifest their element) as "greater physical endurance". You defined the ability of Matoran of Gravity as "resistance to high pressure". What is the difference between these two? Are Matoran of Gravity completely inferior, or does their ability include something special that might balance them out against Matoran of Iron?
A) Please note that these abilities were ones chosen by and voted on by BZPower members. I did not create them, so exactly what the details of them are really needs to come from the people who did create them.
I am not sure why the questioner seems to be confused about this; the definitions he quoted seem self-explanatory to me (nor do I recall offhand if those are exact quotes to what was in the polls). I do not see why greater endurance would have anything to do with pressure. A deep-sea fish might not get tired as fast as a different deep sea fish but would explode just as much if you rushed it up to the surface.
That said, the wording the questioner quotes (likely quoted from BS01's current wording) is a bit less clear than what was in the original poll: “Greater tolerance for carrying weight, water pressure, etc.” Source:

Note that Iron's traits were not part of our polls. I presume that one was Greg's idea. Gravity is actually much easier to confuse with Stone's extra strength than with greater stamina. The difference there would seem to be that Stone is muscle strength, Gravity is cellular integrity. Both (as well as to a smaller extent Earth) would do well holding up a heavy stone for a bit, but Stone could hold it longer, and Gravity could withstand deep-ocean water pressure (and Earth could see in the dark). Iron would presumably have about as much trouble as normal people lifting the heavy stone but could keep on lifting things repeatedly for a longer time period before getting too tired. As I understand it.

Q) How did Takua became a Toa by wearing the Kanohi Avohkii? (It would be awesome if the mask contained fragments of a Toa Stone.)
A) Never been revealed. That was one of those movie script things that didn't necessarily conform to the rules of the universe.
In fact Greg did reveal that Toa can charge up any object with Toa Energy like a Toa Stone, and that the mask simply served that purpose. (The "Toa Stones" that the Toa Metru made in fact were just random rocks they found on the island; there's nothing special about the material used.) He may have forgotten that there. A fragment method is not necessarily impossible, though, as long as they didn't mess up the mask power (presumably they would be mixed in during the forging of the mask when it was molten, so it would essentially be the same as a mask forged to have tiny little holes in it like eyeholes and the like for decoration, rather than cracks that form later which would actually mess up the power). But it's unnecessary.
Greg might be talking about why it only worked when he put it on his face, which he's correct was never revealed (it's been theorized that this simply symbolized "being ready", and even a destined Matoran holding a Toa Stone will not be transformed until they accept responsibility for whatever will happen next, or something like that). Seems the questioner definitely didn't have that in mind; they were asking basically if it had Toa Energy and how so. Greg may have misunderstood what the questioner was asking. They might also have been asking more about who or what provided the Toa Energy, which also has not been revealed, beyond that Artakha was behind it somehow or another.

Q) Would a Toa of Iron be able to, theoretically, morph the metal of their own body?
A) I probably would say no, just because it basically makes him a shapeshifter and thus too much more powerful than other Toa
I believe this is a new limitation, similar to the special limitation on Toa of Gravity and Psionics against absorbing their element, possibly worth mentioning on the BS01 page etc. It is, however, already implied by a previous answer he gave saying they had that kind of special limitation against levitating themselves; see here:
http://www.bzpower.c...t-quotes-stuff/
I notice neither is mentioned on the Iron page at BS01, even though the Ba and Ce limits are. Someone might want to suggest a note about both in the Trivia section.

Q) [Do] you have a name for him [The Shadowed One]?
A) Oh, yes, there is a name for him. But as I told the folks on BZPower way back when, I am not releasing it for three reasons: 1) Everyone hated it when we named Teridax, 2) it robs him of some of his mystique, and 3) it really doesn't matter what his old name was, what matters is who he is now, and who he is now is TSO.
I'm sure he's not being literal with 'everyone', but in fact the first poll that was launched about that infamously left out any option for those that liked the name but just didn't think it was the best ever (but had options for both strong and weak dislike), so it gave a false impression to people who didn't look closely at the options. A later unbiased poll showed fair support for Teridax. Still, his reasoning stands on the grounds that it never got as much support as "Makuta." (Now, that doesn't prove people wouldn't like the Shadowed One's name, but the third point I think overrides this. Nobody calls him that; Teridax needed to be revealed, although a better name choice could have been made, because characters would really have been using it.)

Q) ….were there accents within the Matoran Universe? For example, would a Matoran from Metru Nui sound markedly different from one on the Southern Continent?
A) I think it would be fun if they did
I'm only including this one out of selfish reasons ( 
) -- I'm very glad to hear this as I have relied on it in places in my fanfics (a character theorizes about where another is from based on the accent, etc.). There are several other good revelations in Jag's file others might be more interested in, majorly recommend everybody give it a read-through. I'm just not quoting most of them here as I have nothing to add for those.

Q) Would carapar be in the Red Star?
A) Unknown. I have not made a determination about beings killed outside of the MU yet
As mentioned in the Red Star topic, Greg clearly forgot where Carapar was killed; it was on Tren Krom's island when the team led by Brutaka confronted the ancient monster; he was killed by TK. TK was fused to an island in the right arm of the giant robot -- definitely inside the MU. Greg misunderstood the reason for the question; the issue was whether the apparent weird-disintegration TK used on him counts as leaving a "body" or if that would be more like Matoro and the Makuta. (As I also mentioned in there, there's evidence from other Greg quotes, and Matoro's earlier 777 stairs revival although that wasn't on the RS, that even just dust remaining does count as a body, but with Matoro's final death, there was just nothing, and the antidermis of dead Makuta spreads out too far, etc.).

Q) Why is antidermis green but Makuta's eyes and shadow hand is red.
A) Because Makuta was designed before the idea of antidermis was created.
-- But in case the questioner actually wanted the in-story reason, and might possibly be reading over here (or if anyone else is curious), a serious answer would be that, at least for Shadow Hand, red is the color associated with Shadow (as well as black) element. Green is associated with antidermis. So, the energy itself of the Shadow Hand is dark red, apparently. The eyes are trickier but I guess that Makuta as beings must have the ability to project illusions of eyes in whatever color they want, and Teridax probably chose red because he likes to be associated very closely with Shadow (wore a Mask of Shadow, etc.).
Actually, his eyes have been shown as orange too, and maybe some others, depending on the media involved. Even just as a giant robot, they were shown both as red and orange. I have gone with orange in my retelling because more media showed that than red. (But orange is a mixture of red and yellow, so not that different.)
[Edit: Oh, and yellow in MNOG. Anywho, that doesn't really matter as he's a shapeshifter anyways so might change eye color depending on the emotional image he wished to convey at the time.]

Q) When Makuta took control of the universe, how did his hundreds of thousands of yellow Rahkshi come into being. Did lines that once produced Vahki produce their worms (Forgot their name, sorry) and creating their armor suits?
A) A manufacturing line could not produce kraata. They can only be produced by a Makuta, and you now had a Makuta who basically had godlike powers.
I'd add that a few of the other Makuta were basically enslaved and forced to make more Kraata for a while, and later killed (if memory serves...). I get the impression, although the following is just a theory, that Teridax needed to observe it happening a few times scientifically to figure out how to use his Great Spirit powers to imitate it properly, then killed off his test subjects once they'd outlived their usefulness.

Q) Concerning Nova Blasts: When a Toa performs a Nova blast, the effects take the form of whatever element the Toa is, correct? How about a Toa of Magnetism?
A) Overall, your suppositions seem correct. I would think a Toa of Magnetism would probably create an enormously powerful magnetic field, not a good thing when everyone is at least three-quarters metal.
Page 173 Reply 5:
Q) Would the magnetic field push away or pull in? Having a magnetic field that attracted objects could cause trouble for the Toa.
A) My guess it is will cause problems either way. But you are right, push out makes more sense.
I hope he reconsiders -- pull in makes WAY more sense. Only another actual magnet could be pushed (so Toa armor would be pulled), and even then, nothing would really stop most magnets from just instantly flipping around so now they're pulling. That's what happens with real magnets of significant power. (This is why LOST's Incident pulled metal toward it, not pushed, for example, and one of the Spiderman movies had something similar I think.) Pull out would mean we'd have to invoke the Bionicle physics rule and explain something else away for seemingly no reason; an opposing magnetic field being generated in other metal that turns no matter how the metal turns. It's possible but it implies a serious level of control, and a Nova Blast is supposed to be a losing of control generally.
On the other hand, pull in is already done by Gravity (but of everything, not just metal), so it might be fun for an "antimagnet bomb" to exist in Bionicle. Still, that sounds like something better left to a really experienced Toa doing that on purpose rather than a Nova Blast. Also, we already saw one in the Kal version and that was definitely pull in, so it would contradict that.

Q) When did Makuta think up the Plan? It changed over time didn't it? What was it first going to be, and when did it change to what it was in the end?
A) Makuta basically ran a lot of different plans at once. I think the plan he finally ended up executing really came into full flower at the end of 2003 storyline, when his efforts to control when the Matoran would return to Metru Nui failed.
This is an interesting tidbit. It has been established previously that he first thought of it while trapped in the protocage 1000 years before story present. This doesn't necessarily contradict that, I guess he just means that was the most recent thing that was actually a partial defeat, not just a planned fake defeat, and this forced him to rethink a few details.
It's interesting that Teridax would see that as a defeat; I wonder if the Turaga's time-out for storytelling moved things back into what he'd aimed at, and it was just the loss of control that bothered him? He did need them to return very close to that time so Mata Nui's life could be saved (unless he hadn't been as commited to the takeover plan until that point?). He could not have predicted a destiny to be fused to Takanuva in EP, of course, so this makes sense. He probably would have had a fake defeat of some kind lined up where he would still control the timing -- I wonder what it would have been?

Q) Was Velika really his name, or did he assume it as a Matoran?
A) He assumed it as a Matoran.
Darn it! He had earlier said that it was his original name, and I based some plot on this in my retelling. This was even part of the very first topic about the Velika = GB reveal:
http://www.bzpower.c...being-revealed/
The original quote was: "The Great Being was already named Velika before inhabiting the Matoran body."
Greg is very busy now and forgetful; we should probably take such "re-questions" with salt accordingly, and go with earlier answers, in general. Especially when so much time goes by since the earlier answer that people will have likely incorporated it and there was no hint it was something he hadn't yet set in stone. (Unlike things like whether the RS could revive an MU inhabitant who was on SM at the time, which he was always clear had not been established for a while.) Admittedly, it not being his original name does make strategic sense for him, in case anyone might hear it and connect the two, but until they get back to Spherus Magna there's nobody that would know him as a Great Being (except maybe Mata Nui?). But because of the legal problem with new names, Velika is the only name we're going to get, so it would be much nicer to have it be the original.
He does seem decided on this though:
Page 238 Reply 13:
Q) Is Velika the great being's name?
A) No
Page 240 Reply 4:
Q) Is it possible that Velika's name is derived from his original GB name?
A) Doubtful
I wonder if he recalls that originally he said it was the same? Is this an intentional re-thinking or forgetting his earlier answer? Seriously, now, this is a little like suddenly saying Kopaka wasn't a member of the Toa Mata. Not trying to be negative, but some things just shouldn't be retconned... *grumbles and moves on*
[Edit: Oooh... I just thought of a possible way I could salvage the Velika-name part of my story that might be fun... I may edit, but I'll have to decide quick because a chapter calling him Velika as a GB is coming up soon...]

Q) [Can Legendary Masks be infected?]
A) My guess would be no.
Page 269 Reply 14:
Q) Why? [Can’t Legendary Masks be infected?]
A) Yes, and because I think infecting masks at that level of power would unbalance the story
This could easily be an intentional safeguard-limit added by the GBs (against the risk of a glitching Makuta; they didn't know they might actually become evil). Or, the sheer power of the energy contained in them might just overwhelm any antidermis that entered the mask.

Q) Would you ever consider posting a concluding chapter to The Yesterday Quest, and a concluding chapter to The Powers that be on BioSector01.com? (BS01)
A) I'd like to, it's just a matter of whether I can find time to do it right. I don't want to knock something off that is lousy, just to do something, you know?
Compared to previous answers, this is encouraging. I hope he will.
