the nature of humanity

[Astramentous]

Balcus may have figured out some of the creator tech but he absolutely hasn't improved in it in anyway neither the zoanoid tech nor Artificial control medal seem to be as good as what the creators could produce. The creators made Alcanphel which is more powerful than anything Balcus made, Alcanphel also cannot cure his own sleeping sickness caused by the uranus.

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.

Yes but the creators never intended for zoanoids to fight unit-g's, chances are they developed this class of zoanoids to fight something much weaker.

If they can create and control a being as powerful as Alcanphel as well as steer the course of life on earth Balcus has not yet surpassed them.

Also the ACM can only operate for a short period of time whereas the Guyver seems to operate indefinitely.

There have been a lot of comments about the Creators and their intention for humanity (I didn't quote because this thing would be a mile long) but that was a long time ago and modern humans are very diffrent to the ones the Creators would have been working on. What I mean is that from the point where the Creators left too the events of Guyver, humans have been developing indipendantly of the Creators to the point that humans aren't the ultimate weapons we were.

It makes sense to give weapons the ability to think, adapt and support allies but the Creators would have regulated these traits, but without them humans developt less desirable traits, as weapons that is, such as compasion and empithy. This also explains the human tendancy to factionise without a clear enemy we are still programed to fight.

It's good to keep in mind that this is aplying fictional factors to real world humans, of course real world humans are the way we are because of natural evolution and socio-psychological factors so we should draw a line between use and the humans of the Guyver. Though it is still an interesting thought exercise.
