Metal Bat stated that he can revive through fighting spirit. Does this section of the audiobook mean that humans with enough fighting spirit, willpower or whatever can come back to life? Garou also came back to life when he was killed.
Monsters like Orochi (who was created by ONE) who are capable of this. It seems that humans with enough fighting spirit or willpower or whatever can also come back to life.

>Genos: But that was his first fight with Kabuto and he lasted 3 minutes. That’s pretty impressive.

>Metal Bat: Huh? That’s it? It’s over?

>Genos: You lost, Metal Bat, because the damage you sustained were too grave for you to continue.

>Metal Bat: Huh? What are you talking about? I can totally keep going.

>Genos: No, when you get injured to that extent, it is over.

>Genos: You are considered “dead” in the virtual world.

>Metal Bat: No way Jose. I might have lost in the game world, but in the real world it won’t go like that.

>Metal Bat: It might be over once you die in the game world, but in the real world, a death is just a flesh wound. You can totally revive through fighting spirit and have another go, know what I’m saying?!!

>Sneck: Eh, isn’t it usually the other way?
