Thread: Brain Bomb

Okay, I've heard a lot of things attributed to Gantz that aren't adequately explained, and then I started thinking back to the very beginning of the manga.
We know that there's a bomb/microchip in each hunters brain, that can somehow up-link with Gantz and detect if they leave the mission area. However, given what we know about the rest of Gantz's technology, I think its safe to assume he can fit a lot more functionality into such an implant.
For starters I wondered why it was attached directly to the brain. I know the Mangaka probably doesn't write every page with Anatomical correctness in mind, however most contemporary ideas for "brain implants" have them mounted on the inside of the skull, not the brain itself. Then I started thinking maybe the chip handles Input and Output signals with the brain. I believe this could explain several previously unexplained phenomena.

1) Revival.
If the chip can up-link a hunters position with Gantz, as well as a hunters physical state (IE alive or dead), Than wouldn't it also be possible, given Gantz's technology, to upload a current copy of the hunter to gantz, rather than reviving them from whatever was recorded during teleportation? I know this is phrased awkwardly, however its been argued by a few members here that Gantz records/updates each hunters body and soul every time they are teleported, and that when they die he reloads from the "last save point", however this doesn't account for a hunter's memories up until his time of death, my theory does. If Gantz does treat the hunters like players in a video game, then it would make sense to "save" right before going off to fight a boss or mini-boss, right?

2)Locked doors.
Several questions were raised as to why the door to the backroom had been locked up until Izumi went in to get his sword, however if one looks back towards the first volume of the manga, one would realise that the doors and windows were never locked, but rather they couldn't be touched (Pg 53, Vol1, Ch2).
When one considers that the chips are capable of producing a ringing sensation in one's brain, perhaps it is also possible to directly interface with the brain's motor-skills faculties. All the chip would have to do is send out a few signals to a few nerves/muscles and it would basically be able to nullify a persons attempt to preform a certain action. Perhaps this also explain why they can't physically harm Gantz, or at least haven't tried. This sort of chip-output relates more so to my third and final point.

3)Memory.
So lets say you get 100 points and choose option number one, you go free and have your memory erased. While it doesn't go into much detail as to how this takes place, I doubt it completely wipes ones memory, but rather just during the period of time for which one knew Gantz. otherwise Izumi, and possibly Sakata would be left with the mental capacities of infants. However to accomplish this Gantz needs too things: A recording of ones memory prior to knowing Gantz, and a means of erasing and re-implanting that memory, should a hunter choose option number one. I believe the brain bomb chip is capable of both of these, as hinted at in my previous two points.

I think that you have some interesting thoughts here...

I never thought of the bombs in the brains as anything else other them bombs themselves. Actually, I didn't actually believe there were bombs inside their heads until I started reading the manga, since you can't see it in the anime. I've always thought that idea to be too much Battle Royalish, and since I hate that movie, I discarded the idea.

Second, you're linking a lot of thoughts to the idea that this bomb might be a chip that can do a lot more. That's also something I haven't considered. What I do consider is that Gantz might be more of a pseudo-omniscient being, aware of much more. It seems like he did notice the way Tae saw and created a record of the players when she went to Roppongi, so maybe that means something. She doesn't have anything inside her head, besides her... brain. I'm not sure there are other evidences right now, though.

As for the door, I think most of us agree on the fact that it was always open and nobody noticed. I think it probably opens when the ball itself opens (not before), and that's something Izumi knew. Simple as that. People just get so distracted with the open sphere and everything it has inside that they just didn't think of trying the doors again. Doesn't matter if you've played games before, either. Others reactions and your own preparatives for the game are enough to take your attention.

Those are really good theories, I agree with them. If the chip records everything their bodies do, then that would explain how Gantz knows about Kurono's boners, Inaba trying to act cool, etc.

-Rah

not nessarily, gantz can pick people up just as they die remember, so that means they dont have the chip in their heads, also it means he knows they are going to die, which must surely mean he knows when kurono has a boner.

Very cool thoughts

I don't think so. Nishi pull two fingers in Gantz's ear and if gantz could paralize the hunters, I think he wouldn't allow to do that sort of things.

Nishi talks to him like a sort of "pet". "ey don't ignore me!".

I'm more agree with tetnubis opinion, but I respect your theories too

I think that another function of the chip is to tell whether a non-hunter has been told about Gantz.

The chip probably could detect the brain waves that involve telling someone about Gantz (which is probably why Nishi could get away with his website. The chip couldn't detect him writing about it on the net. Perhaps you could have a conversation by paper on Gantz??)

Then again, Gantz could detect when Tae took a picture of one of the gangrapers and thus blew his head up so perhaps that idea is bunk.

Yet if that were the case and Gantz was able to see everything, how come Nishi's didn't die because of his website?

What about this one. Gantz blows up people's heads when he WANTS. Maybe he decides whether he wants to kill someone or not. Tetsuo was being an idiot and abusing the power that was given to him when he tried going against the people that killed him with that gun, so Gantz probably got pissed and blew him. And maybe for some reason he didn't get mad at Nishi for the site, so he was just like "OK".
