Every Joy Boy Ability in One Piece, Ranked From Mythic to World-Shaking

One Piece just dropped a couple of episodes that light a fuse under one of the series' biggest mysteries: Joy Boy. We finally get a look at his silhouette and feel the sheer weight of his Haki, and now the fandom is revisiting everything tied to him: the Void Century, the Ancient Kingdom, the actual One Piece treasure, all of it. Joy Boy is no longer just a historical name; the show is actively putting his powers on display, and they are directly tied to the world's buried history and to Luffy, who is very clearly walking the same path.

So, what exactly can Joy Boy do?

The series has now tipped its hand on a handful of Joy Boy's abilities. Some of this is lore-deep, some of it is pure power flex, and some of it is both. Here's how it shakes out right now.

1. Hito Hito no Mi: Model Nika
   Joy Boy's Devil Fruit is believed to be the Hito Hito no Mi, Model Nika, a mythical Zoan tied to the Sun God Nika, who symbolizes laughter, freedom, and liberation. In plain terms: it gives rubber-like properties, and once awakened, it lets the user fight with total creative freedom, bending their own body and even the environment in ways that should not be possible.

   Wano laid this out when Luffy awakened his fruit and the series revealed that the 'Gomu Gomu no Mi' was actually the Nika fruit the whole time. The World Government buried the real name because of its connection to Joy Boy. That reveal effectively cements that Joy Boy had this fruit and awakened it long before Luffy did.

2. Haki
   Joy Boy's Haki is portrayed at the absolute top tier. His Conqueror's Haki is so dominant it affects people without direct clashes, and his will is so overwhelming it can still push events long after his death. The recent episode goes bold with this: the Iron Giant, Emet, unleashes Joy Boy's strongest Haki attack using a knot Joy Boy gave him. The blast is so intense it takes down the Five Elders, and Imu senses it all the way in Mary Geoise and literally jolts. A giant channeling stored Haki through a keepsake knot is a wild detail, but it tracks with how the show treats willpower as something that can be carried forward.

3. Voice of All Things
   This is the big one from a lore perspective. The Voice of All Things lets the user hear and understand voices normal people cannot: creatures, objects, ancient beings. That plugs directly into Poneglyphs, the Ancient Weapons, and the erased history of the world. It is not a flashy combat skill, but it is the key to the deepest parts of One Piece.

   Joy Boy's recent on-screen conversation with the Iron Giant confirms he has this ability. It reframes him as more than a legendary fighter; he is a central figure whose return to the narrative is setting up major change once the story reveals more about him.

Why this matters right now

Between the silhouette reveal, the Nika truth, and Emet's Haki moment, the anime is basically telling us Joy Boy isn't just backstory. His powers are woven into the present, and Luffy is echoing him in ways that point straight at the Void Century, the Ancient Kingdom, and the treasure itself. If you felt the ground shift, you weren't imagining it.

What other abilities do you think Oda is still keeping under wraps for Joy Boy? I have a feeling this list is going to grow.
