The question of who would win in a fight between Garp and Sengoku has always sparked heated debates, but the latest One Piece chapter 1166 basically gives us the answer. Yes, it’s Garp!
Even while heavily wounded, Garp clearly looks like he has dealt a brutal defeat to Sengoku, even leaving a large bump on his head. This is one of the most severe injuries we’ve seen in the series.
Based on the information from chapter 1166, it’s reasonable to assume Oda gave Garp a power boost, because the gap is just too big. Previously, the two were almost evenly matched, making it hard to tell who was stronger. But in this situation, Garp seems to be completely dominant over Sengoku.
Garp vs Sengoku: We finally have a winner

Fans can’t believe Sengoku struggled so much even while Garp was in a “nerfed” state. It feels like Garp was fighting with just 1 HP, yet still had the upper hand. At this point, people are joking that even a half-dead Garp is too much for Sengoku, and that might actually be true.
Before, everyone thought Garp and Sengoku had roughly equal strength, but their specific advantages were always debated. Some argued Garp’s raw fighting power gave him the edge, while others believed Sengoku’s Devil Fruit abilities offered more versatility.
But after this chapter, claims that “Sengoku is overrated” are growing louder. The manga’s latest images show Sengoku struggling, making it seem like he’s been overestimated all along, while Garp continues to show incredible strength even when he should be weakened.
Garp’s role in the God Valley story deepens

Regardless, after everything that has happened in recent chapters, Garp’s role in the God Valley incident is becoming far more significant than anyone expected. Every new detail shows he was involved in more than the Marines have admitted.
First, there’s the revelation that Garp saved his son Dragon and helped him escape from prison. That alone is a major turning point, completely changing how we see their relationship and Dragon’s past.
Then, he teamed up with Roger and actually defeated the Rocks Pirates. This legendary feat highlights just how extraordinary Garp’s power and influence were during that era.
And after all this, he’s still celebrated as the Marine Hero. Honestly, it’s no exaggeration to say this is the most defining period in Garp’s life, and we’re still uncovering more about it.
