They are trying to prevent the one piece superweapon from being fired and destroying the redline because it would unlock easy trade routes and the increased commercial activity would rapidly push the world into the modern age. Once technology advances beyond a certain point, the anti-machinerons will show up on Earth to genocide all humanity, like they've been doing on every planet with intelligent life since time immemorial.I am stoned right now.
>>285175963>the anti-machineronsAh yes ""the reapers""
>>285175963I can see Oda doing that and I can see Oda pulling the next chapter that the anti-machinerons are gone/left and it was a bunch of paranoid old men marinating in their own power.
>>285175963that's just the plot to TTGL
>>285176736And Kill La KillAnd Mass Effect
the reason the celestial dragons own the world is because they were the ones that put the planet back in one piece after it was split apart and the red line is just the scar left over from where the planet was healed while the grand line is where the planet's magnetic poles currently lay (they used to be located where the red line currently is). one piece is just the history of what led to this disaster and the devil fruits were made from joy boy to combat the super weapons.
>>285175963in some aspects the One Piece world is already very technologically advanced, why doesn't stuff like Vegapunk's inventions trigger the anti-machinerons?
>>285178197Because 50000 years haven't expired yet.
>>285176811>And Kill La Killno it isn't. In KlK the main villain WANTS to bring the evil alien overlords to earth to enslave them. In TTGL and OPs fanfic the evil overlords try to prevent it
The final of Skies of Arcadia is a good hint.It seems to be built on the same idea, just with fewer moving parts.
