When Eiichiro Oda finally pulled back the curtain on the Rocks Pirates through manga flashback sequences, fans spent weeks parsing every background character. While heavyweights like Whitebeard, Big Mom, and Kaido dominated initial discussions, sharp-eyed readers noticed a different detail hiding in plain sight: non-human crew members, specifically the Fishman connection.
Understanding how fishmen integrated into Rocks D. Xebec's terrifying armada changes how we view the pre-Roger era, racial dynamics across the Grand Line, and the pipeline that later fed into crews like the Sun Pirates. Let's break down what the source material actually reveals about this forgotten chapter.
Who Were the Fishman Members in the Rocks Crew?
The crew led by Rocks D. Xebec wasn't an organization built on friendly bonds or ideological equality; it was an alliance of violent powerhouses. Oda's manga panels and official databooks confirm that the crew's roster extended beyond human and oni members to include fishmen.
The most prominent named fishman tied to this era is Barbel, a massive catfish-type fishman who served as a combatant under Rocks. Standing larger than standard humans, Barbel participated directly in major operations, including the fateful invasion of God Valley. Beyond Barbel, background panels during the crew's assembly on Hachinosu feature humanoid fishmen and aquatic fighters acting as officers rather than background fodder.
These fighters possessed the baseline traits of their species—ten times the physical strength of an average human combined with advanced combat training and Haki proficiency. They weren't passive slaves or reluctant recruits; they operated as core enforcers for a captain who sought to conquer the world.
Equal-Opportunity Brutality vs. Racial Liberation
A common misread in online spaces is assuming that Rocks having fishmen on his ship meant he was a progressive champion of cross-species rights. That interpretation collapses under scrutiny.
Rocks was an equal-opportunity predator. He recruited anyone who possessed overwhelming strength or utility, regardless of whether they were human, giant, oni, or fishman. The World Government's systemic oppression of fishmen meant that powerful aquatic fighters often found themselves marginalized or criminalized by default.
- Tactical Opportunism: Rocks didn't recruit fishmen to liberate Fishman Island; he recruited them because their underwater mobility and brute strength gave his crew a tactical edge during coastal raids.
- No Ideological Code: Unlike Fisher Tiger later, who founded the Sun Pirates to free enslaved people, Rocks operated purely on ambition.
When you examine how characters like Jinbe or Arlong later navigated the seas, you can trace structural echoes back to this era. The Rocks Pirates proved that fishmen could operate at the absolute highest tier of pirate infamy, setting a brutal precedent before the concept of the Sun Pirates even existed.
The God Valley Catalyst
The ultimate destination—and graveyard—for this multi-species experiment was the God Valley Incident. Occurring thirty-eight years before the current timeline, the clash brought the Rocks Pirates into direct conflict with the World Government and a temporary alliance between Gol D. Roger and Monkey D. Garp.
During the chaos on God Valley, fishman members fought alongside human commanders. When the crew fractured following Rocks' defeat, the surviving members scattered across the globe.
- Some fishman survivors drifted into obscurity or formed smaller regional factions.
- The collapse of centralized chaotic conglomerates like the Rocks crew forced aquatic outcasts to rethink how they survived a world dominated by the Celestial Dragons.
This history establishes a direct line between the chaotic freedom of Hachinosu and the organized resistance later built by figures like Fisher Tiger. Even though Tiger's ideology directly opposed the wanton destruction favored by Rocks, the structural blueprint of a powerful cross-species crew had already been tested decades prior.

Frequently Asked Questions
Did Jinbe ever sail with the Rocks Pirates?
No. Jinbe was too young to have sailed under Rocks D. Xebec. However, some early theories conflate younger fishman crew members from the Rocks era with Jinbe's generation. Jinbe's formative pirate years began later with the Sun Pirates under Fisher Tiger.
Why did fishmen join a human-dominated crew like Rocks?
Given the severe systemic discrimination enforced by the World Government, powerful fishmen often found human-dominated pirate crews to be the only places where their strength was valued rather than hunted or subjugated.
Are there other fishmen mentioned in the Rocks crew besides Barbel?
While Barbel is the most explicitly named and detailed fishman, Oda's crowded flashback panels include several unidentified humanoid fishmen and aquatic combatants among the crew's officer ranks.
Does the Fishman connection change the main plot of One Piece?
It deepens the world-building by showing that species integration among outlaws existed long before Luffy's journey or even Roger's era, proving that the struggle for fishman equality has deep, complex roots in the criminal underworld.
