Summary
One Piece hints at Joyboy's treasure as a weapon to defeat the World Government's Ancient Weapon. The Roger Pirates learn of Joyboy's identity and intentions, leaving behind an important tool for Luffy's generation. The Iron Giant's technology, aided by Joyboy's abilities, may hold the key to ending the war against the World Government.
The world of A piece, created by Eiichiro Oda, is one of the secrets and mysteries that remains unsolved. The truth behind the titular treasure is perhaps the biggest of them all. For years, fans of the series have debated what this iconic item could be and why Roger and his crew didn't take it themselves.
In chapters #1115 and #1116 of the One Piece manga, Oda may have hidden clues about what the treasure Joyboy left behind could be. This item can be a weapon or an item of equipment that helps Luffy defeat or neutralize the Ancient Weapons controlled by the World Government. Only someone with Joyboy's abilities can use this device, which is why Roger cannot use it himself.
This item can only be used by Joyboy's true successor
Besides Joyboy, the only known individuals to have set foot on the legendary island of Laugh Tale are the Roger Pirates. It shows that when they arrive at that location, Pirate King Roger started laughing uncontrollably. This led fans to speculate that Joyboy's treasure was something no one would believe, like a bottle of sake or even a spaceship. However, Vegapunk's revelations in chapter #1116 may indicate that this item was the tool Joyboy left behind to defeat the World Government.
When talking about the Ancient Weapons that threaten to destroy the world, Vegapunk wonders why Joyboy doesn't destroy them. The scientist also revealed that the Roger Pirates always knew about Joyboy's identity and intentions because they were able to learn about them during their time in Laugh Tale. Upon hearing these words, Rayleigh, who used to be Roger's right-hand man, just smiled and thought that Vegapunk was ruining the fun of young pirates in the world. Even after hearing this news, the Shadow King's indifferent attitude may imply that he is not worried about the future.
Rayleigh may have been aware of something the new generation of pirates could use to defeat the dangerous and destructive Ancient Weapons. This may be related to what Joyboy left behind in Laugh Tale, an item that only his successor can use that would destroy or neutralize these mythical artifacts. Roger may have laughed in the faces of the Five Elders when a weapon powered by Joyboy's successor's imagination was used to defeat them. Rayleigh, who knows about that tool, is waiting for the new generation to own it.
Egghead's Iron Giant proves to have technology aided by Joyboy's abilities
The giant only works when he hears the sound of the liberation drum
The Iron Giant, an ancient technology that appears to have a deep connection to Joyboy, proves that whose technology is enabled by Joyboy's abilities. The robot warrior remained dormant for decades until Luffy's Gear 5 transformation heartbeat brought it back to life. This theory gains strength from the fact that Oda, like Vegapunk, seems to be focusing specifically on the Iron Giant. When the scientist questioned the reason behind Joyboy's refusal to destroy the Ancient Weapon, York realized that the transponder snail transmitting Vegapunk's message was hidden inside the machine.
Since the start of the Egghead Island arc, the Iron Giant has been heralded as vital to the Straw Hats' survival. Oda might be hinting at that There exist other technologies like that one, powered by Luffy's heartbeat.. UK scientists may have created this type of technology to help Joyboy in his fight against the World Government. Unlike the Ancient Weapons, which can be used by anyone, these tools can only be used by someone with Nika's power.
As a last resort, Joyboy can use a weapon capable of destroying or neutralizing the dangerous Ancient Weapons created by his people. Realizing he was incapable of defeating Im and his army, he traveled to Laugh Tale, where he hid the tool. Roger, knowing that he would never be able to use this device without the Liberation Drum, left it there for the Next Generation to find. Once Luffy obtains this weapon, he can end the World Government's reign of terror and save the world from being flooded.
The secret that the Roger Pirates kept hidden for decades may be about to be revealed in A piece story. Once this information is made public, the war against the World Government will most likely begin. Whatever happens, it is almost certain that Luffy and the One Piece treasure will be vital to the world's survival against this powerful enemy.
