Captain John: The Original Magnet Master
Captain John, a member of the infamous Rocks Pirates, has been confirmed as the last known user of the Jiki Jiki no Mi before Eustass Kid. For longtime fans, the clues were hiding in plain sight throughout the series.
In previous chapters, John appeared with a metal arm, leading to speculation about whether he possessed magnetic powers or was simply a cyborg like Franky. The God Valley incident finally settled this debate once and for all.

The God Valley Betrayal
During the chaotic God Valley incident, Captain John’s true nature was exposed when Imu arrived and pirates scrambled to escape with treasure. Instead of helping his crewmates, John betrayed the Rocks Pirates by using his magnetic abilities to attract all treasure boxes toward himself.
His greed proved fatal. Shortly after using his Devil Fruit powers, Captain John was shot down by his own crew member, Ganzui. This dramatic moment not only confirms his Devil Fruit abilities but also explains how the Jiki Jiki no Mi became available for the next generation.

The Kid-Captain John Connection Explained
The parallels between Eustass Kid and Captain John run deeper than just sharing the same Devil Fruit. Here’s why this revelation is significant:
The Name Mystery: Kid was introduced as Eustass “Captain” Kid, believed to be inspired by the real-life pirate William Kidd (also known as Captain Kidd). William’s father was Captain John Kidd, also a pirate. This real-world connection made fans suspect a narrative link between the two One Piece characters.
Shared Power: While we don’t know if they’re blood-related in the story, both characters wielding the Jiki Jiki no Mi creates an undeniable bond across generations.
The Treasure Armband: Remember the armband Luffy gave to Buggy—the key to finding Captain John’s treasure? Fans now theorize that this armband will only react to magnetic forces, making Eustass Kid essential to unlocking its secrets.

What This Means for Kid’s Future
Despite his devastating defeat against Emperor Shanks, this revelation suggests Eustass Kid still has a significant role to play in the One Piece series. His magnetic powers might be the key to discovering Captain John’s legendary treasure, potentially setting up a comeback arc.
The Jiki Jiki no Mi remains one of the most versatile and powerful Devil Fruits in the series. Kid’s bounty of 3 billion berries after defeating Big Mom alongside Law proves just how formidable this ability becomes in skilled hands.
