Goodbye Gear 5? A new theory suggests Luffy could become even stronger in ‘One Piece’
As battles grow more intense, fans wonder if Luffy’s ultimate form is still incomplete.

It’s been three years since Gear 5 made its explosive debut during the Wano arc of ‘One Piece’, transforming Monkey D. Luffy into the embodiment of the Sun God Nika. The moment shook the fandom, and the internet, but now, a new theory is gaining traction: what if Gear 5 isn’t Luffy’s final form after all?
Is Luffy missing a key element?
Throughout the series, depictions of Nika often show the figure wielding a sword, spear, or shield—yet Luffy has never used a weapon in this form. Could it be that his transformation is still incomplete? Some fans believe that unlocking the full potential of the Hito Hito no Mi, Model: Nika may require more than just imagination—it might demand a legendary weapon to truly awaken the fruit’s divine power.

The mystery of Joy Boy and untapped potential
One of the biggest twists in 'One Piece' lore was the revelation that Luffy’s Devil Fruit wasn’t the Gomu Gomu no Mi, but a mythical Zoan-type fruit tied to the ancient figure Joy Boy. While Luffy’s Gear 5 grants him cartoonish freedom and reality-bending abilities, recent battles suggest he hasn’t yet reached the same level of power Joy Boy once held.
This has led to speculation that Eiichiro Oda may be holding back a final upgrade: one that could involve a weapon or artifact tied to Nika’s legacy. Whether it’s a sword forged in Elbaf or a relic hidden in Laugh Tale, the idea of Luffy gaining a new tool to amplify his powers is becoming more plausible as the series nears its climax.
Elbaf: the proving ground
With the Elbaf arc currently unfolding, Luffy faces some of his toughest challenges yet. It’s the perfect setting for a new transformation—or revelation—to emerge. Whether or not he picks up a weapon, one thing is clear: Luffy’s journey is far from over, and his power may still be evolving.
