Thread: I have a Gantz theory that explains near EVERYTHING

Now before you chew me out for thinking I'm some know-it-all newbie. I'll give a little bit of info on my self. I've been lurking these forums for the past 3 years, and the manga was my only source of entertainment in my first months after purchasing a home. I'm pretty sure I've read every episode's thread and think you guys are awesome. I don't think I'm awake enough to write a multipage theory but I'll try to make it thorough enough to catch my drift. If you have any "What about X?" questions, I think I can answer them.

If you don't like long stories. Read the parts in bold as Cliffs Notes

Okay, here we go - Chronological Order

Several Hundred years ago , there are several races living in semi-harmony throughout the galaxy. As highly advanced aliens are prone to do, they start travelling from planet to planet. At some point, a relatively small number of aliens come to earth (via teleport, I assume) to live a fresh new life in disguise and multiply. After a few mishaps in keeping their presence undetected, (ex. roswell) Earth becomes aware of the aliens' existence not as spaceship invaders but long-time inhabitants with questionable intents. The aliens at this point just want to live out their lives unnoticed.

To counter this foreign presence, Humans develop nano technology to create vampires and fight off the aliens. At first the vampires are well supplied with weapons, money, organization, and technology to aid in spotting the aliens (ex. their sunglasses). I don't know how vampire-to-bes were chosen. My guess would be a lottery in which the government picks out and injects the nanos into people who have a good fighting ability (similar to Gantz recruitment without the deaths). The battle between aliens and vampires rage on under the cover of darkness for several decades until Humanity makes a new discovery - The Akashic record.

Quoting wikipedia, the Akashic records "are described to contain all knowledge of human experience and the history of the cosmos". This girl who accidentally patches into this goldmine of knowledge then begins to spill the beans on the not-on-Earth Aliens' technology which would also be contained in this record. The Gantz technology would replace the vampires in the war against the interstellar immigrants. The old man in Germany quickly spreads the Black Ball technology to several countries so that they can each exterminate the aliens one by one.

From here on, I'm going to refer to the on-earth aliens as "immigrants". "Aliens" from here on refers to the guys who never left their alien homeplanet(s) and got to play with all the cool technologies for the past hundreds of years. The no-longer-needed Vampire organization is cut off from the government and left to live in the streets and live less-than-glorious lives as their numbers dwindle. It is at this point that the Vampires set their sights on the Gantz participants as revenge. The existence of Gantz now threatens the existence of both Vampires and the immigrants - leading to an uneasy alliance. The Vampires are much fewer in number, so their ability to combat Gantz is limited. Now heres the plot twist:

Sebastian catches word of Humans copying Alien technology from the Akashic record and decides to wipe them out before they become too strong. The first step was to gain influence over the source of information (the german girl and her father's company). Second step was to deal with the 2nd largest threat: the millions(?) of long-term immigrants (who are potentially very powerful) who've gotten cozy on Earth. In reality though, Sebastian and the true aliens could kill the immigrants easily. He's letting the Gantzers fight because apparently the Germans want to gamble on who the better fighter is. (In his travels, he for some reason teaches Sakata an ability that is yet to be revealed by the the german girl. Perhaps he was to be a human vessel in case things went wrong)

Under the supervision of Sebastian, the technology of Gantz was modified a bit. The Y gun would send the immigrants to Sebastian's planet/ship to be punished/executed/interrogated, he'd include a time limit & rewards so that the Gantzers are too rushed to ask the aliens & immigrants whats really going on, and he put in a monitoring device that would kill any tattle-tellers and keep the weak Human population out of the loop. (eventually he turns it off because "Fuck it! Everyone knows now anyway"). As the attacks against he immigrants continue, the immigrants start rising up and showing their muscle. Sabastian realizes that eventually the immigrants will overpower the tiny gantzers and their tiny weapons. The countdown to "Fuck it. Kill them all" aka Katastrophe begins. The Roman 'aliens' had nothing to do with Katastrophe. They were immigrants who were so pissed that they were getting in larger numbers and starting to make serious damage against the gantzers. Coincidentally this comes right as the countdown hits zero (hence the early return teleport). The balls are turned off because it's invasion-time!

Katastophe begins when Sebastian's army comes down to punish humans for exploiting technology stolen from the aliens. I don't know if the immigrants are on Sebastian's side or not but I think they'll get killed in the battle just because they're a potential threat to the true aliens. This is why the devil-looking alien talks of a God. They're talking about the aliens of their home planet who have the power of Gods and can kill any one of them without a problem (Sebastian's psychic powers being only an example). The immigrants are really some low-tech aliens who've been out of the loop for several hundred years - thats why they live in apartments and not space ships (Onion Alien) and no longer wield guns. To the immigrants, the invading aliens are gods above, comparatively speaking.

Sadly with all this said I still don't know how this series will end. This is a pure guess but I think A) Everyone will die or B) The gantzers will Y-gun themselves onto the mother-ship/planet and kick ass or C) Uncover a doomsday weapon inside the big black ball in Germany (remember that?) and use it on Sebastian/the mother-ship/planet.

Okay, tear my theory apart guys! I'm looking forward to it

Many questions like in any theory, 'cause Oku just unpredictable. I myself think aliens might be trying to create weapon from humans, and catastrophe is date of main test to see if they succeeded or not IMHO.

Several Hundred years ago , there are several races living in semi-harmony throughout the galaxy. As highly advanced aliens are prone to do, they start travelling from planet to planet. At some point, a relatively small number of aliens come to earth (via teleport, I assume) to live a fresh new life in disguise and multiply. After a few mishaps in keeping their presence undetected, (ex. roswell) Earth becomes aware of the aliens' existence not as spaceship invaders but long-time inhabitants with questionable intents. The aliens at this point just want to live out their lives unnoticed.

If the different aliens races had come to Earth via teleport, there'd be no reason for them to have lost their technology, rather they should've improved it.
And also, their technologies differ quite a bit, as one can notice from mission to mission. Regarding their disguises, we see for instance the Onion alien who maintains a humanoid form, though doesn't have a well developed vocabulary, and lives in a human apartment.
We've seen the Tanaka aliens, who use actual robot shells in order to breath - that's the only "true alien" we've seen so far imo. They have some knowledge of human language, though also limited, and multiply rapidly (taking into account the number of young Tanaka's and baby Tanaka's)
We've seen aliens who disguise themselves as statues (budha arc).
And we've seen aliens that maybe have taken the form of existing human structures (Italy arc; the same might als apply to the Dino aliens).
Now, we have the Oni aliens and vampires, who live alongside humans. Vampires eventually prey on humans.
We don't know enough about the Chibi aliens, only that apperantly they lived incognito on some rooftop. Also, they can shapeshift, though also in a very limited fashion if compared to either the Nurarihyon (who had complete morphing powers) or the Oni aliens (which could also shapeshift as an inate ability).
But there's also the Ring aliens, who have gotten their form from the Lord of the Rings; that, to me, it's too much of a human thing for the aliens to pick on their own. Take into account their size and how they could've appeared at the hunt location and I say we add 1 point to the theory the aliens are man-made.

To counter this foreign presence, Humans develop nano technology to create vampires and fight off the aliens. At first the vampires are well supplied with weapons, money, organization, and technology to aid in spotting the aliens (ex. their sunglasses). I don't know how vampire-to-bes were chosen. My guess would be a lottery in which the government picks out and injects the nanos into people who have a good fighting ability (similar to Gantz recruitment without the deaths). The battle between aliens and vampires rage on under the cover of darkness for several decades until Humanity makes a new discovery - The Akashic record.

The vampire sunglasses and lens spot Gantzers in another frequency/ surely, if so, they could spot other aliens during missions, but off-mission we haven't seen aliens being capable of using stealth, only Gantzers.

"Similar to Gantz recruitment without the deaths"? The only time in which that happened was with the vampires themselves; Gantz hasn't done anything of that sort before.
And though it certainly proved a (very brief and almost meaningless) power-up to the team, there's also the issue of Gantz reason for letting the vampires in possibly being also to show them they're no threat, or just for the heck of it (see what would happen inside the team, and with vampires having to fight aliens), also because they pose no threat.

Although the vampires, so far, have been a unique sort of enemy (partially human, partially alien/monster), and that can be created without direct contact with the main vampire clan, I'd say it's a big step to bet on them being alien hunters.
Mainly because they've proven to be on the alien side all along. The'ye shared technology with the Oni aliens, they tried to have an agreement with the Youkai aliens.
They know of the alien language and feed on humans. To me that classifies than as no ally to humankind.

Quoting wikipedia, the Akashic records "are described to contain all knowledge of human experience and the history of the cosmos". This girl who accidentally patches into this goldmine of knowledge then begins to spill the beans on the not-on-Earth Aliens' technology which would also be contained in this record. The Gantz technology would replace the vampires in the war against the interstellar immigrants. The old man in Germany quickly spreads the Black Ball technology to several countries so that they can each exterminate the aliens one by one.

It was already stated that the girl is only a transmitter, so it's not of her doing to "spill the beans", it's someone's intention. We still aren't clear on who that someone is. It could be Sebastian, it could be someone Sebastian is working for, or it could be someone completely unrelated (though I think it's unlikely).

From here on, I'm going to refer to the on-earth aliens as "immigrants". "Aliens" from here on refers to the guys who never left their alien homeplanet(s) and got to play with all the cool technologies for the past hundreds of years. The no-longer-needed Vampire organization is cut off from the government and left to live in the streets and live less-than-glorious lives as their numbers dwindle.

The existence of Gantz now threatens the existence of both Vampires and the immigrants - leading to an uneasy alliance. The Vampires are much fewer in number, so their ability to combat Gantz is limited.

It was stated on the seminar chapter that the quarrel the vampire have with Gantzers are solely due to retaliation, because the Gantzers have attacked the vampires (not the aliens as a whole, but vampires).
But the quality of the translation comes into question. It'd have to be re-checked for sure.

Sebastian catches word of Humans copying Alien technology from the Akashic record and decides to wipe them out before they become too strong. The first step was to gain influence over the source of information (the german girl and her father's company). Second step was to deal with the 2nd largest threat: the millions(?) of long-term immigrants (who are potentially very powerful) who've gotten cozy on Earth. In reality though, Sebastian and the true aliens could kill the immigrants easily. He's letting the Gantzers fight because apparently the Germans want to gamble on who the better fighter is. (In his travels, he for some reason teaches Sakata an ability that is yet to be revealed by the the german girl. Perhaps he was to be a human vessel in case things went wrong)

I don't believe Sebastian would "catch word" of the humans copying alien technology, mainly because as already stated before, it was the will of some entity to use the girl as a transmitter and not something the girl stumbled across.
Also, if Sebastian had an interest in eliminating the alien races, with his power, he could probably do it quite easily. Also, just who is Sebastian to begin with? Is he human? Alien? Something else? We don't know, hence we can't say he'd be in any way threated by the alien races.
Now, to say Sebastian has taught Sakata his powers... that's going a bit overboard, huh? The powers are quite different. It suffices to notice that Sakata's powers has some restrictions, one being the damage to his internal organs, and another the need to use body movements to direct the power (as seen with the classical hand movement).
Not to mention the scale of the powers. At least to me it seemed Sebastian was creating specific events, while mocking Kikuchi and without much effort, as if reality were his playground all along.
The powers origin is unknown, and we can't link it to Gantz. Sakata's mention when he first gets to the room is too vague to serve as conclusive.
As for my own thoughts on this, I think the powers have nothing to do with Gantz or Sebastian or aliens; it'd just be a specific and rare human phenomenon.

Under the supervision of Sebastian, the technology of Gantz was modified a bit. The Y gun would send the immigrants to Sebastian's planet/ship to be punished/executed/interrogated, he'd include a time limit & rewards so that the Gantzers are too rushed to ask the aliens & immigrants whats really going on, and he put in a monitoring device that would kill any tattle-tellers and keep the weak Human population out of the loop. (eventually he turns it off because "Fuck it! Everyone knows now anyway"). As the attacks against he immigrants continue, the immigrants start rising up and showing their muscle. Sabastian realizes that eventually the immigrants will overpower the tiny gantzers and their tiny weapons. The countdown to "Fuck it. Kill them all" aka Katastrophe begins. The Roman 'aliens' had nothing to do with Katastrophe. They were immigrants who were so pissed that they were getting in larger numbers and starting to make serious damage against the gantzers. Coincidentally this comes right as the countdown hits zero (hence the early return teleport). The balls are turned off because it's invasion-time!

Well, the Catastrophe seems something planned for the whole word, and so far the ones who've really gotten their ass handed to them were the humans and not the aliens.
And the gantzers don't really have "tiny" weapons. They have mechas, flying units, h-guns and a lot of shit. If alien hunting was the purpose, they'd be dead already. The purpose of it, as the factory owner mentioned, is amusement. Bets.
That's the human purpose, but the "Source"'s purpose probably doesn't differ that much, since it was the Source who gave humans this technology to begin with.

As for the countdown getting to zero, that probably happened on the day the sky turned red, we can't really be sure of that since Oku wasn't kind enough to show us the counter again.

Katastophe begins when Sebastian's army comes down to punish humans for exploiting technology stolen from the aliens. I don't know if the immigrants are on Sebastian's side or not but I think they'll get killed in the battle just because they're a potential threat to the true aliens. This is why the devil-looking alien talks of a God. They're talking about the aliens of their home planet who have the power of Gods and can kill any one of them without a problem (Sebastian's psychic powers being only an example). The immigrants are really some low-tech aliens who've been out of the loop for several hundred years - thats why they live in apartments and not space ships (Onion Alien) and no longer wield guns. To the immigrants, the invading aliens are gods above, comparatively speaking.

Most aliens didn't even know what was going on, so I highly doubt they regard a certain type of alien - which hasn't even been proved to exist - as their gods.
Once again, I think it's quite the opposite: no alien tehcnology was exploited by the humans, the humans were exploited by whoever/whatever is the source of the woman's formula.

Well, for now that's it. Excuse any typos, I might check on it later, but right now I'm too lazy to revise the text.

To put it short i guess gantz world's theory is more like "The Matrix" or "Serial Experiment Lain". Only unlike matrix kurono and co doesn't get controlled by machine but by people with money betting on them. THat's my theory anyways.

not quite feelin' ya man...

it looks like (to me at least) that the aliens are man-made, maybe there's some alien message being received by that PHat girl but no real intermission of any real alien yet

Kurono's brother was a vamp, wasn't he? he wasn't recruited... tht thing that I can't resolve in any of my own theories (or anyone's elses) is the existence of this vamps and why they are against gantzers: it doesn't make any sense that they hunt gantzers, they seem to know a little about gantz, but gantzers only attack aliens in their missions, how could they know about them if this mission only take place once in a while and they are not announced anywhere?? the only explanation to that would be that the people gambling over their heads would have told them, and that's illogic, they wouldnt have any reason to go kill them or to hate them

^ the most twisted unfitable thing in the majority of theories (been jealous does not look like a reason worthy dying for... not for the vamps, for sure!)

It's a f*****g Wolrd cup. The hunt is the qualifying. Now its the final stage..katastrophe is the country vs country..

Akira didn't realize he was a vampire until the nanomachines, assumed to be responsible for the replacement of humans cells for whatever the vampire race is, led him to the seminar, in which we also learn that the reason for vampires to attack gantzers is because they've been attacked first. In any case, I suppose we'll see more of the vampires in the Izumi/Nishi prequel currently in develpoment.
To me it seems very likely that the vampires were the targets in the times Izumi lead the previous team.

^ Agreed. I'm also with Cali on his second huge post of corrections and additions, though the rest of the first post has some interesting stuff in it. It seems that Sebastian is really using reality as his playground. I'd like to discuss more on Sebastian going on Nishi's webpage and him possibly being the one who gave Kikuchi the image of the huge ball from Germany.
Also, despite Sebastian doing the "Well, what about this explanation?" bit, I think that organisation was responsible for building the Gantz equipment and gambling on the hunts from his daughter's signals, but that is just the little picture, Sebastian losing it as he talks about Reality being a devil's playground and Nuri's words... theres something bigger that'll happen in the Final Phase (lame that Phase 2 is like only 7 volumes long...)

I'm impressed with how well thought out, and written your theories are. Major props.

Anyone notices Sebastian eyes? They were sharp just like Gantz's eyes? Whatever did happened to him?

My prediction; That the whole black ball room was a trail to see how humanity will interface with new technology and "unique" circumstances they are thrown into. It seems to me that the most reoccurring theme is the psychological impact of these scenarios. Emphasizing determination, the will to survive. A dissection of the human psyche if you will.

at any rate i hope the manga doesn't end with either Kurono looking towards the reader, holding up two fingers in the shape of a gun and yelling "bang"

would Sebastian be an Agent Smith like character. But in the sense of protagonist vs antagonist it seems he has no equal so far unless he/she/it is in the big black ball....which gives kurono a power level of over 9000 perhaps? this is tooooo predictable and direct to be true
