Garp and Dragon’s true relationship has finally been clarified in One Piece Chapter 1166 — and the truth completely rewrites decades of fan assumptions.
For more than a thousand chapters, fans believed that the bond between Garp and Dragon was broken beyond repair: a Marine hero ashamed of his son, the most wanted revolutionary in the world. It turns out the story was never that simple.

Instead of rejecting Dragon’s rebellion, Garp secretly supported him — and even freed him from prison after the God Valley Incident. Rather than abandoning each other, the two chose different battlefields to pursue the same idea of justice.
Following the legendary fight where Garp and Roger defeated Rocks D. Xebec, Dragon faced serious consequences. During the chaos, the young Marine disobeyed direct orders to protect civilians, saved Shanks and Shamrock, and even neutralized a World Noble in order to protect Kuma.
To the World Government, these were unforgivable crimes.
Dragon was arrested — and the world assumed that Garp turned his back on him.

But history took an unexpected turn: Garp visited Dragon in prison, made his defining decision, and broke him out. It was the moment that transformed Dragon from a disillusioned Marine into the man who would later establish the Revolutionary Army.
Ironically, the organization that now shakes the World Government every day only exists because Garp gave Dragon the chance to fight for his own justice.

Chapter 1166 reframes everything fans have heard Garp say about Dragon over the years. His frustration, joking insults, and dramatic rants were never sincere contempt — they were a shield to protect both of them.
Garp stayed within the system.
Dragon tore down the system from the outside.
Both fought for the same ideal: justice for the innocent.
Garp understood Dragon’s actions at God Valley were morally right even if they violated Marine protocol — and helped shape the world silently from behind the scenes.

Before this flashback, Garp and Dragon had never appeared together in the same scene, despite 1,160+ chapters. Oda deliberately waited for the most meaningful moment — the God Valley Incident — to show them side by side.
It wasn’t meant to be a casual reunion.
It was meant to be the moment history changed.
With Chapter 1166, the God Valley flashback that began in Chapter 1153 finally reaches completion:
Rocks is defeated
Roger acquires Shanks
Dragon becomes the world’s most wanted revolutionary
Garp silently becomes an indirect founder of the Revolutionary Army
The consequences of that day still shape the world of One Piece in the present timeline — proving that God Valley was not just a tragedy, but the birthplace of multiple legends.
