In the diverse world of the One Piece series, Gunko stands out with a unique ability that distinguishes him from his peers. Despite his low profile, Gunko wields the Aro Aro no Mi, a fruit that grants him remarkable powers and versatility.
The Aro Aro no Mi is a Paramecia-type Devil Fruit that allows its user to create and manipulate various types of names. This ability enables Gunko to control movement and attributes associated with these names.
Below, we will explore the impressive capabilities of the Aro Aro no Mi in One Piece:
1. Control Over Sleeping Individuals

If someone falls asleep, they could be influenced and controlled by Gunko’s various names.
This capability becomes a significant advantage in strategic plans involving the inhabitants of Elbaf within the World Government. Notably, one of Gunko’s most formidable opponents, the Killingham Fortress, could fall victim to the effects of his abilities while they are asleep.
It remains unclear whether Gunko’s names can have a simultaneous effect on multiple targets that are awake.
2. Amplification
Gunko’s names can also be utilized to amplify power levels. The various creatures in the Land of the Giants have been used to bolster Gunko’s strength and performance significantly.
Specifically, the amplification ability of these names could potentially relate to the scene where Imu amplifies Cobra and Sabo in Mary Geoise, although it remains uncertain whether this is intentional.
3. Acceleration of Attacks
Gunko can increase the speed and effectiveness of his attacks simply by following the trajectory of the names he has created.
By directing the various attack paths, Gunko can further enhance the speed and intensity of each attack. The result is that the potency of his attacks can become significantly more formidable.
However, this technique has its drawbacks. Gunko’s attack paths can be apparent through the names, leaving him vulnerable to counterattacks from opponents. Even Loki, despite being blindfolded, can still sense Gunko’s attack trajectory.
Unfortunately for Loki, while he is busy dodging, he is unaware of the impending threats from Gunko’s powerful names.
4. Illusions
Each name created through the power of the Aro Aro no Mi can also produce illusions against the target. When a name is invoked, the target’s perception can be altered.
The wolf that attacked Gunko in chapter 1136 felt this effect keenly.
5. Embed Names into Equipment for Greater Attack Efficiency
In chapter 1137, Gunko was able to embed his names into his shoes for a short period, enhancing his height and size. Not only that, but Gunko could also imbue his names into gloves, increasing his overall mass significantly.
With large feet and arms, combined with his quick reflexes and adeptness in utilizing his names, Gunko’s attacks become even more devastating against opponents like Loki.
6. Create Flying Devices
The Aro Aro no Mi is not just useful for attacks. Gunko has previously harnessed his abilities to create a bird-like structure, which he then utilized as a means of aerial transport. This ability greatly aids his mobility and that of other World Government members.
Through his skills in amplifying, controlling, and creating illusions, Gunko is a truly creative user of the Aro Aro no Mi, showcasing the extensive potential of his Devil Fruit powers.
