The entire One Piece world has been deceived! Luffy’s Gomu Gomu no Mi Devil Fruit is not an ordinary power. Recent developments have uncovered a shocking truth: this Devil Fruit holds the ultimate power that the World Government has tried to erase from history.
Specifically, Luffy’s Devil Fruit is actually the Hito Hito no Mi, Model: Nika, a mythical Zoan type. This fruit has been fiercely hunted for over 800 years because it poses a massive threat to the Government’s authority. It wasn’t until Luffy awakened this power during his battle with Kaido that fans witnessed its true destructive potential.
The “Fearsome” Power of Joy Boy and Nika

The Hito Hito no Mi, Model: Nika was first used by Joy Boy, a major figure during the Void Century. His awakened power became such a threat that 20 kingdoms united against him. Although the World Government tried to bury this truth, the Five Elders have always sought to seize the Nika Devil Fruit. They managed to obtain it, but 13 years ago Shanks stole it from Who’s Who and kept it until Luffy accidentally ate it.
When Luffy activates Gear 5, he not only unleashes Nika’s power but also embodies the spirit of Joy Boy. The entire world was shaken, with the giant elephant Zunesha believing Joy Boy has truly returned. The existence of this Devil Fruit terrifies the World Government because it symbolizes freedom and rebellion. This is why the Five Elders took direct action, determined to eliminate Luffy at Egghead before he becomes an even greater threat.
A Unique Offensive Power

The awakening of the Nika Devil Fruit has changed the entire One Piece landscape. Luffy’s power now rivals the Four Emperors in both physical strength and Haki. Although Gear 5 usage is still limited by time and drains immense stamina, its offensive power is undeniable.
With Nika’s power, Luffy has demonstrated unmatched offensive abilities: overwhelming Kaido, defeating Admiral Kizaru, and suppressing Rob Lucci. However, what fans have seen is only a fraction of its true potential. Once Luffy fully masters this power, he will reach a “godlike” level, strong enough to overthrow the World Government and Imu. This capability places the Nika Devil Fruit at the top as the ultimate offensive weapon.
