I'm not even sure we'll see Gon again and you're talking about Gyro? Come on.
I think we could see Gyro or at least one of his followers in this arc. That Dark Continent expedition is a big deal, it would be weird if he wasn't interested in it but yes that encounter with Gon isn't happening anytime soon.
Gyro is a
rough plan for future plot. just like Maha or Alluka.
If the story need to focus, we will see what happen to him but if not we dont.
for now, I think BW and DC is the ending arc and unnecessary to return to Meteor city or Gyro.
I think we are going to see Gyro again
BEFORE we see Gon again.
That is Gyro will be the catalyst that
puts Gon back into the story and it
makes perfect logical sense. Here is why:
Gyro is in Meteor City which was taken over
by the Chimera Ants. I know the Spiders mercy killed some former residents but
I believe there are much more still left.
Kakin announced to the entire world that
the Dark Continent exists.
Gyro was able to run a large drug operation
on NGL even while maintaining a facade
of a tech free island.
But now Gyro is most likely presumed dead.
I mean he IS dead as a human. However his
malicious will lived on to his reborn ant self.
So while the Ant King was very strong his one
“weakness” was he did not know who he was
whereas Gyro NEVER forgot and likely CAN’T.
While the story was focused on Mereum
Gyro has been in the background rebuilding.
Welfin showed us that although Gyro is said to be evil he is still extremely charismatic and does not simply rule through fear.
Therefore Gyro already having an extensive operation on Meteor City is very likely.
Gyro knows about the Dark Continent.
Why does that matter?
Simple. Because the Chimera Ants which destroyed NGL and wrecked Meteor City
came from the dark continent.
Even if Gyro does not know that fact if he knows the dark continent exists then
it’s logical to assume that is where the ants
came from. Therefore Gyro knows the
ants came from the dark continent and that
such information had been suppressed.
Armed with such information and his
malicious will what would Gyro do?
Well if you want to spread evil around the world you would tell all the residents and
stir them up towards a world revolution.
Meteor City residents are extremely radical already. But imagine how they would feel if the Chimera Ants who destroyed the only home they ever knew were from a secret world.
Of course they are going to be livid.
And Gyro is exactly the worst person to have on the worst island at the worst time.
If you thought Mereum was a problem...
Gyro is going to really shake things up.
Either Gyro or the residents of Meteor City
are going to be interested in exploring the
Dark Continent. I mean it would not be a
stretch for them to believe a cure for their condition is over there.
If Gyro finds out about Don Freecss
and the book he wrote where would
Gyro go (or rather send invaders to go)?
The answer is Whale Island
And that will be how Gon comes back.
Now I am NOT saying all of this will happen
next chapter. This will obviously take a while
however I do believe once the Dark Continent
Expedition team is on the New Continent
we are going to see the Gyro plot ramp up.
Therefore I believe we will see Gyro again
very soon possibly next chapter.
I am expecting we will have four interconnected plots
1. The actual dark continent expedition
2. New Continent
I believe the black whale will sink and
the survivors will BARELY reach even the
New Continent. Lots of people will need
serious medical care
3. Gyro’s revolution and inevitably
the invasion of Whale Island
Of course Gon will defend his home
4. and maybe Killua and Alluka.
Although they may not show up til the
last moment and it’s possible Alluka
will fix everything but at the cost of
“Something” returning to the Dark Continent.
I believe at the end of HxH the world will
think the dark continent was just a myth
if they even know about it at all.
