One Piece Chapter 1166 dropped a huge breaking revelation and twists things up! For over a thousand chapters, Garp complained about his revolutionary son while Dragon created an army to destroy the World Government. Everyone assumed Garp's relationship was irreparably broken, with the Marine hero ashamed of his criminal son.In reality, Garp famously did not only accepted Dragon's rebellion, he freed him from prison after God Valley and went on to be a "founder of the Revolutionary Army." The father and son were never at a break in their relationship aside from picking different battlefields to fight for similar justice.Garp dodging the attacks of Xebec (Image Source: VIZ)After that epic battle, where Garp and Roger defeated the notorious Rocks D. Xebec, came the fallout for Dragon. In the attack, the underage Marine rogue'd his own superiors while saving civilians. He also rescued the young future pirate Shanks and Shamrock and tranquilized a World Noble trying to shoot the future revolutionary Kuma. In retrospect, this was a serious crime in the World Government's eyes.After Dragon did all those things, he was jailed. The World Government caught him cause of what he did at God Valley. But, just like Marineford, Garp came to see his son in jail and did something that changed history forever.Garp's Defining Choice for His Son in One PieceDragon is taking the marine ship to help those he rescued (Image Source: VIZ)The Marine hero freed Dragon from custody, recognizing that his son's actions stemmed from genuine justice rather than criminality. This is when Dragon set out into the world to start the Revolutionary Army and became known as "the world's worst criminal." Ironically, because of Garp's actions, the Revolutionary Army continues to fight against the World Government, literally to this day.This creates a huge context for their relationship throughout One Piece. While Garp was never opposed to Dragon's beliefs in what he was doing, he preferred to work in the establishment while Dragon fought outside of it. Garp knew Dragon's actions at God Valley weren't wrong, even if they violated Marine protocol.The First One Piece Interaction Between Father and SonBefore the God Valley flashback, Garp and Dragon had never appeared together in the same scene despite over 1,160 chapters. Oda evidently wanted their interaction to feel organic and right, and the God Valley incident was very fitting for that to happen.Monkey D. Garp and Roger as seen during the God Valley Incident (Image Source: VIZ)Oda decided to showcase their relationship during such a historically powerful moment in the story. Rather than simply interacting in a mundane encounter, Garp and Dragon's first shared panel together occurred during one of the biggest moments of the 1 piece world. On one end, Dragon is seeing his father fighting alongside Roger against the Rocks. On the other end, Dragon is grappling with the atrocities of the World Government.For years, One Piece readers interpreted Garp's remarks regarding Dragon as genuine frustration or disappointment. Oftentimes, the Marine would rant and rave about his child's actions and seemed to vent and display frustration at family functions. It raised the eyebrows of many One Piece readers on the surface that the father was embarrassed by his child's lifestyle.Chapter 1166 reframes these moments entirely. Garp wasn't genuinely upset about Dragon's revolutionary work. He performed for the benefit of his Marine colleagues and superiors who might question his loyalty. His complaints served as cover for the fact that he philosophically agreed with his son's mission, even if he chose different methods.One Piece Chapter 1166 Completes the PictureChapter 1166 sorta flips everything we thought about these moments. Garp wasn't really bummed out about Dragon's revolutionary work. Garp acted in favor of his Marine friends and superiors who might question his disposition. His barks at Dragon were just ca over because he philosophically supported his son's work, regardless of the way he went about accomplishing that work.The latest chapter wraps up the epilogue to the God Valley flashback that started in Chapter 1153. After 13 chapters in 5 months, the readers finally understand the full context of how that day drastically changed the modern One Piece world. Not only did Rocks get defeated and the Roger Pirates now have Shanks, but Dragon became a revolutionary leader from an ex-Marine disenchanted with his position.This newfound understanding enriches the entire One Piece narrative, showing how the God Valley incident created ripples that still affect the present day. Without Garp's intervention, the Revolutionary Army might never have existed, and the world would look vastly different.
