Astramentous

I've checked around a bit, and I can't find any definitive frame from the manga that shows exactly what happened to guyver 2's medal after being ejected from the suit. A lot of the earlier manga pages were pretty loose with details on smaller things like that, but... ...the animations don't explicitly show what happens, either. I always assumed it was destroyed by Sho's mega smasher, but we know later on that the guyver control medals can survive a mega smasher easily(to the point where Sho is vaporized, but his control medal isn't even singed). So what happened to it? It should be mostly intact, somewhere. It feels like Chronos would have looked for it at the site, but they don't seem to have found it. So where did it go?

It's also possible the CM would integrate the zoacrystal inside of itself, but that is a bit far-fetched. I personally suspect the CM would sink into the crystal, or else split the crystal to either side of it. But the guyver unit would definitely power up a zoalord. The creators were terrified of that happening, after all. Just adding the power of a guyver to a zoalord wouldn't be enough to scare them that much - not when they had the technology to shoot a moon at the Earth. The guyver would have to increase the zoalords powers beyond what it does for a normal human to make them that terrified.

That, or it's air compressed and launched with gravitational force. That could be an interpretation of the pressure in the name. But I'd guess from the way it has been portrayed that you are correct, the pressure cannon is just a lump of compressed artificial gravity(artificial since there is no mass in the center).

Most likely the Control Metal is not organic. It almost certainly has organic components to interact with the bio-boost organism, and likely takes a cell sample of the host to re-grow their body, but I doubt it's actually based in organic structures. Whether or not the control metal was made with organic tools is another matter, of course, but the basic metal is probably made of inorganic materials and is not a living substance. That being said, some really sophisticated machines can repair themselves to a limited degree, so it's possible the control metal could have done so given time - but I'd guess not. The Control Metal is such a dangerous thing to have malfunction, it'd be better to separate it from the host entirely and then repair it and test it in a laboratory. In an emergency, perhaps an emergency system was in place to perform temporary repairs, but such would probably not be up to par. However, this doesn't mean Sho can't repair his CM. The Gigantic's control metal fits over the Guyver's - it may have the capacity to repair his control metal, and even may keep a copy of his and Agito's minds just in case. Also, I have a question with Guyver IIs control metal - when was it damaged? Was it really just that little bomb that damaged it, or was it something before that, perhaps from the creators ship? Did we ever get a good picture of all three units with undamaged Control Metals?

Gastal's invisibility seemed to be similar to adaptive refractive skin, but more more advanced. Adaptive refractive skin is a chemical seal that can be applied to ceramics, which causes light to refract around the ceramic when in a 360 degree coating. But the most advanced form of that is still pretty visible, and the stuff's so fragile that putting it on a car let alone a person would be nearly impossible. But the point is to bend and control the visible spectrum, but this same gunk distorts the Entire spectrum, including ultraviolet, infrared, x-rays and the other umpteen categories. It's just not very effective with anything outside the visual spectrum with our current tech. Now, if you could make a much more advanced version of that stuff, then you could get a cloaking system that would work very well for the Guyver. It requires very little energy and can be secreted, or perhaps expelled as a aerosol over the surface of the guyver, and could then be used almost indefinitely. Using EM to distort light and bend it is a high powered way of doing the same thing, but there it is - High powered. For the Gigantic, power is an actual concern, so you'd want to conserve it. On the disintegration the high frequency spear boasted - that would have been due to discordant frequencies. The high frequency vibrations would travel along the spear without interfering too much with themselves, then overlap at the tip of the spear, causing it vibrate enormously and be able to penetrate many things. But more importantly, as the vibration connects with something, if tuned properly, it will radiate into the target with discordant frequencies. The target will undergo rapid vibration of adjacent tissues at different frequencies, and they'll literally shake apart, which translates to dissolving when you look at it acting on a human body.

This reminds me of the Ark - didn't someone say it was supposed to be able to travel through hyperspace, but needed the zoalords to do so? It's conceivable that for short bursts, a number of them together could activate such an effect without the ship as a medium.

Ah, but the zoanoids shown being mowed down by Guyver 0 were the standard ones in use at the start of the series - since then, there are entirely new, vastly improved strain of zoanoids, like the upgraded gregole type.

I'm not sure if they took the technology or what, but they claimed they modified the humans into zoanoids, suggesting at least competence with that technology - but if it took the creators millions of years to develop that stuff, how did Balcus manage to learn and improve on it in only a few hundred years? That'd suggest that humans are many times as intelligent as the creators, or at least much more creative. As for the guyver, assuming all the images shown are lies and the guyvers were left there intentionally, then there's a number of possibilities. The guyvers were left there to provide an opponent for the zoanoids, to force them to increase their power. The guyvers were left there to find out if humanity with only three guyvers was still mightier than all of the zoalords and zoanoids combined. Or perhaps the creators were already doomed, and knew it - and wanted to leave a race to succeed them. With the guyver units and a functional ship, humans might have been able to make more, and become the new Uranus. Just a few suggestions on how you could run with that idea.

Sho Vs Sean - the problem here is, at some point Sho accepted the Guyver as neccesary to keep his friends safe. Sean, on the other hand, keeps thinking about how much he hates being the Guyver. If the guyver reacts to your subconscious, Sean may be weakening it to a ridiculous degree. He may even have power amps, but due to his experience with martial arts and frame of mind, simply be keeping them turned off. The power amps are probably the most essential part of the armor after the control metal and gravity controller - they allow the guyver to keep his footing when firing the mega-masher, punch and grapple with incredible strength, and enhance stability in movement. They probably also contribute to the "excess body heat" the head beam supposedly uses for power. If they're turned off because the user believes they have a certain weight and that won't change or because he hates the armor, the armor has to limit several of the its functions to compensate. So, that is the reasonable explanation, in-universe, for why Sean's guyver abilities are pathetic. In such a state, Sean would have absolutely no chance of beating Sho. If he got over it, and had a similar frame of mind, then the only difference is in training and build. Sean would likely be at an advantage. He could certainly beat Sho if neither of them transformed.

I don't know about you, but I have a lot of freedom. I write professionally - I've made enough money at that I can sit around and do nothing for the next twenty years, and still be fine. Even while working, I set my own hours and work for whoever I want - I own my own house, and quite a bit of land to boot. I also live in the US, which helps. So no, I don't agree with you - there are people who are free. Plenty of them - they've just worked harder and longer than most to get that freedom. Oh yes, and behavioral science has thus far failed to have anything like consistent results, so good luck with that argument. Now, on to something that matters more than complaining about the real world - the Creators story doesn't work. They had incredibly advanced technology - there's no way they'd need millions of years to create a weapon. A new, intelligent race, maybe. But a weapon? Not buying it. There's also the matter of the guyver's connecting to the navigational spheres - the images they're immediately shown are the same from one ship to the next. Why is that, then? It suggests the ships were left there with a specific message for humanity, and more importantly, the Guyvers. And why would they leave behind a functional ship with three Units on-board? That's awful sloppy for a super-intelligent race.

I'm inclined towards a direct vibration. For example, if you apply vibrations to the skull just behind the ear, then the owner of that ear will "hear" those vibrations. If the exterior of the guyver in that region simply registers the sound waves as air pressure and translates them into vibrations applied to the base of the skull, then all the organs for such a process would be internal. It'd also be able to protect the host's hearing by dampening harmful noise.

You can't see sound - if it got to the point where the air was vibrating enough to see vibrations like that, without causing airflow in the surrounds(shock waves) then the laws of physics are already broken. The Guyver has been shown to blast just about anything with that sonic buster of his, but that could be brute force or resonance. If you produce consecutive resonance waves, you can cause destruction like that to individual molecule types in succession, destroying just about anything, mixed materials or no. If you use brute force, rather than bubbling up, it'd be more likely to cause immolation - molecular vibration = heat in that case. I'm inclined towards the resonance, mainly because that makes the computational and analytical capacities of the control medal more impressive. Wasn't the original disscusion here about how much the guyver can take? It can take anything that doesn't destroy or damage the control medal. That includes 1.5 mega-smasher blasts hitting directly - which have been shown to cause atomization in just about anything they hit - stone, metal, zoanoid, zoalord - makes no difference at all. If the Control medal can survive that, the guyver can probably survive a nuclear explosion as well. If we're talking about body armor strength, the guyver's body armor has to be strong enough to resist its own blows - if you assume the guyver's arm weighs around 20 kg, and that increases to 200kg for a heavy punch, and factor in that a normal human punch already hits with close to ten fold the weight of the arm - then you get that the force of such a punch is around 2000kg - or close to five tons. Compute the PSI of that for the front armor on the guyvers fist(which is among the thinnest and weakest on the guyver) and you get ~370 PSI. If the guyver can punch with that much force without damaging its hand, than its armor can stand up to any of the weaponry used in any war to date, excluding nuclear devices and large explosives. If you consider heat, a 3900 C flame thrower having so little effect the guyver didn't even show discomfort means it can stand considerably more heat than that. Also, about filament bulbs - they do indeed get hot, but the source of that heat is extremely small. With a flame thrower, the heat is spread over a much larger area, but is measured at a selected point - usually in the center of the flame, at about half the effective damage range. Therefore a flame thrower with the same heat output as a filament bulb has hundreds of thousands of times the amount of energy being delivered to a target. If you want to argue with this, first go find out what a normal flame thrower outputs and its temperature - because I seem to recall they don't come anywhere near as high as 3900 C, and still somehow do a lot more damage than a 4000 kevlin bulb. Edit: When I say PSI here, I'm referring to impact PSI, not static PSI. Completely different formulas and methodology there.

I'd guess the armor was originally a much more basic parasite - still with some interesting properties, but more like a normal life-form. It was manipulated to have two main features - high growth rate, and an organizable cell structure. With an organizable cell structure, you can create super-strong materials, advanced mechanisms, and some very machine-like objects. The ships are probably a further use of the same organism, just a much larger one. If you ripped out their navigation orbs, they'd probably turn into some horrific monster just like the bio-boost creature.
