What if Luffy remained imprisoned in Impel Down
A human who ate the Hito Hito no Mi. Straw Hat Luffy.
What if he had lost to Magellan and remained imprisoned in Impel Down?
Would One Piece have ended there?
If at that time—
What if, on the eve of Marineford, Luffy had been unable to escape from Impel Down?
If Bon Clay had not risked his life, if Ivankov's miracle had not occurred, and if Luffy had remained locked in that abyss of a prison.
Would the story of One Piece have even been possible?
This "what if" is not merely a hypothetical. It is a question that cuts to the core of the story.
What would happen first (1): Ace would definitely be executed.
This is beyond debate.
If Luffy could not break through Impel Down, he would never reach Marineford.
In other words—
Ace would stand on the execution platform,
Whitebeard would start the war, but
the "little brother who came to save his brother" would not appear.
At this point, the route where Ace survives is completely eliminated.
The story would confirm the death of the brothers in an even more hopeless way.
What would happen (2): Whitebeard would die even sooner.
Luffy's presence changed the "flow" on the battlefield many times.
The charge toward the execution platform,
the explosive rise in morale.
The symbol of hope for the pirates
Without any of that, Marineford proceeds under the complete control of the Navy.
As a result, Whitebeard is likely to be defeated sooner and more quietly.
The "end of an era" is declared even more mercilessly.
What happens ③: The pirate era cools down rapidly
After the Summit War, Luffy becomes the "surviving symbol".
Roger's bloodline
Dragon's son
The man acknowledged by Whitebeard
It was because these three points overlapped that the next era "began to revolve around him".
But what if that symbol had vanished in the depths of Impel Down?
The pirates would think:
Everyone who dreams will be crushed
As a result, the concept of the Pirate King is pulled back into being a "legend" once again.
What happens ④: His crew cannot move forward
Luffy's crew is strong. But it is not power that drives them.
The conviction that "he is out there".
Because Luffy is alive,
Zoro swings his sword
Nami draws her charts
Sanji fights
If Luffy were missing, presumed dead, or a prisoner forever.
They would grow, but they would no longer see the same future.
The Straw Hat Pirates might have even disbanded somewhere along the way.
Impel Down, the "grave"
Impel Down is not just a prison.
Name
Dream
Will
It is a place that strips these away and turns you into a symbol called a "prisoner."
Luffy might have been smiling even there.
However, the world needed his smile.
Conclusion: A world without Luffy loses hope
If Luffy had remained imprisoned.
One Piece would no longer be a story of "inherited will."
It would be
a record of a world where those with dreams are erased one by one
.
Luffy did not save the world.
But the fact that he "remained free" kept the world moving forward.
That is precisely why, if Luffy were to remain locked up in Impel Down, even if he were alive—
as a story, he would be dead.
However...
