Merfolk¶
![]()
A fish tail in the water, legs on land: the fastest swimmers of the sea, who lose it all to a Devil Fruit.
| Size | Mermaid 1, Great Merfolk 1.25 |
| Sub-races | Mermaid, Great Merfolk |
| Passive | Merfolk Body, and one more for each sub-race |
| Techniques | 7 |
| In the abilities menu |


In 3D: drag to turn, scroll or pinch to zoom. The buttons switch between the two sub-races. On land, both have a man's legs.


The tail¶
The tail comes out when a merfolk swims off the bottom of the water, or under it. Their legs shrink up into the hips as it grows, with a burst of bubbles, and it waves faster as they swim. Standing in a shallow, the legs stay. Back on land the tail goes the same way, drops falling from the hips. Leggings and boots are hidden while the tail is out.
Two sub-races¶
| Sub-race | Size | Tail | Passive | |
|---|---|---|---|---|
| Mermaid | 1, a man's | coral | Swift Tail | |
| Great Merfolk | 1.25, a fishman's | grey-blue | Great Body |
Merfolk Body¶
Passive, merfolk
The user has a fish tail in the water: they swim faster than anyone in the sea, and breathe and see in the dark under water.
| Stat | Value |
|---|---|

With a Devil Fruit the user loses all of it, unless a Bubbly Coral keeps them dry.

| Stat | Value |
|---|---|
| Swim speed | +50 % |

| Stat | Value |
|---|---|
| Toughness | +2 |
Techniques¶
In the abilities tree, a branch only merfolk see: Undertow first, then Tail Sweep and Sea Escort, then Siren Song and Princely Fist, then Trident Assault and Ultramarine. Each one has its own pose and water effects; the trident is drawn as one.
