MAJOR things that were never played out in the anime
for me:
- what if they had just done nothing?? I SERIOUSLY thought this was the point of Gantz for a long time!! Especially after the Temple Alien told them, "Why did you start attacking us?".
I REALLY thought, that at the end, the Kurono Alien mission, that they would do nothing, and EVERYONE would return when it counted down and something would happen. Like Kurono would go back in time to when he was on train platform.
- Old woman. SEriously!! Who was she?? What did her character signify??
- Teleporter gun. WHY WEREN'T THEY USING THIS EVERYTIME??
I mean this is big plot-hole for me! They didn't like killing right?? So why didn't they just decide to use the teleporter gun everytime!!
Again, I perhaps thought that if they did a mission using just this gun and no-one died, they would all win or something. I EVEN thought somehow that the aliens were all actually humans! That Kurono actually knew! This idea was massively boosted when the Temple Alien actually told Kurono it was human and then Kurono himself became an alien target! (I think I'll make another thread about this)
And so, of-course, it was never explored where the teleporter gun actually takes ppl!!
- the guns only worked sometimes!!! The guy shot that Nishi kid and nothing happened! Why!?
- Just the aliens!! They almost seemed more like nightmarish demons to me, which led me to believe that perhaps the whole thing wasn't really real, like it was a simulation or something. But they're never explained at all!!
probably a few more I forgot but these are the major ones
