Think logically.
1. They never appeared after that
2. They are on a huge alien space ship with huge giant aliens, who think humans are annoying bugs.
3. No gantzer is with them
Lol, how about heights? Your telling me he somehow became a genius parker?
Also, for some reason I cannot see that innocent little kid training himself to the maximum like some buff martial artist obsessed guy like Kaze.
Here, the little kid gets kamikazed by aliens and his suit goes down.

But then here, you could see the suit is suddenly back to normal.

I doubt a little kid can climb up to a 2nd story...
Well, I'm pretty sure climbing up walls aren't that hard with that suit on lol. It's probably like how you see kids on monkey bars. The kid has gotten the grasp of the strength the suit gives him. He can also imitate easily.
I feel bad for Nerdo losing his leg. I guess he is permenatly out, unless Gantz starts working again.
Anzu is hawt, I think she will inspired or have a increase in moral after Kurono's team rescues him and Nerdo in some epic bad ass fashion.
Back to bump this back. Now that I think about it, this idea still does not work.
If it's so easy to transfer people and regain their limbs, wouldn't the hackers able to use gantz as a instant aid kit that will bring you back to full condition as long as your alive?
I personally think those "bugs", are genetically engineered creatures made to fight against humans, for pure entertainment in the arena.
Either way, this whole Arena thing reminds me of Aliens vs Predator .
Guys, if you realized, the Crab like Alien thing could've been genetically engineered by the giants, and the giants hacked the black ball and used them to teleport the Crab like Alien they genetically engineered. (They may have even done if specifically as a weapon to kill humans)
