The Iron Giant is a legendary robot that attacked Mary Geoise 200 years ago. It was originally created 900 years ago, around the time of the Void Century, for a yet unknown purpose. It was inactive due to running out of energy, and is kept on Egghead.[1][2] After hearing the Drums of Liberation from Monkey D. Luffy, the Iron Giant powered back up.[3]

Appearance[]

The Iron Giant is a robot around as tall as the Ancient Giants. It wears a horned helmet, and its face and lower body are covered by grills with vertical bars. The left horn on its helmet broke off over two hundred years ago, and remains missing.

Personality[]

Despite being a machine, the Iron Giant does appear to be fully sentient and capable of emotion. After waking up from its slumber, it apologized to Joy Boy.[4]

Abilities and Powers[]

The full extent of its abilities is currently unknown as it ran out of energy before causing damage. However, it was able to climb the Red Line and was considered to be far beyond the scientific knowledge of the time. It later served as inspiration for Vegapunk's Vegaforce-01, however, he was unable to replicate the mysterious Ancient Energy (古代のエネルギー, Kodai no Enerugī?) power source of the Iron Giant.[2]

The "Drums of Liberation" are somehow able to power it up, although it is still unknown how exactly this happens. Its armor is extremely tough, providing it protection from explosions and high temperatures, as it was witnessed wandering through a massive fire and relentless bombardment from a Buster Call while seemingly unbothered.[4]

Luffy determined that it is supposed to move autonomously, as he could not find a place for people to pilot it from the inside.[5]

Weapons[]

It is shown to be wielding a polearm of some sort during its attack on Mary Geoise.

History[]

Past[]

Iron Giant Attacks Mary Geoise

The Iron Giant attacks Mary Geoise.

The Iron Giant was originally created around 900 years ago. 200 years ago, it suddenly appeared out of nowhere and attacked Mary Geoise, but ran out of energy before causing damage. The World Government subsequently ordered a group of scientists to destroy it, but they chose to hide it instead to study it in secret. It eventually fell into the hands of Vegapunk.[2]

Egghead Arc[]

The Iron Giant was accidentally discovered by Luffy, Chopper, Jinbe, and Bonney during their stay on Egghead.[1] Luffy attempted to climb inside the robot but was unable to, determining that it was the type that moved by itself. They were then interrupted by Vegapunk who warped into the room, and later explained the history of the Iron Giant.[5][2]

Iron Giant Bombarded

The Iron Giant is bombarded by the Marines.

During Luffy's battle against Kizaru, he activated Gear 5, which led to the Drums of Liberation reaching the Iron Giant, causing its eyes to light up.[3] When Luffy later activated his Gear 5 form again, the Drums of Liberation triggered the Iron Giant to start moving.[6] Fully awake, the Iron Giant walked through the flames from the Buster Call and mentally apologized to Joy Boy.[4] As the Iron Giant continued to make its way across Egghead, Marines surrounding the island attempted to bombard it. Despite the heavy bombing, the giant was undeterred, and continued on its route with little issue.[7]

Trivia[]

  • During their attempts to get the Iron Giant to move, Luffy and Chopper try calling it by the names Robonosuke (ロボの助, Robonosuke?) and Roboking (ロボキング, Robokingu?).[5]
  • Robin mentions that 200 years ago was also the year discrimination against Fish-Men became an issue, suggesting it may be connected to the Iron Giant.[2]
  • The Iron Giant shares its name with the Iron Giant from the 1999 animated science fiction film.
    • Both Iron Giants share a few similarities, such as being gigantic autonomous robots and that both of their exact origins and purpose are currently unknown.
