Major spoilers for One Piece Chapter 1166 have surfaced, and fans are calling it one of the most pivotal chapters since the God Valley flashback began.
Eiichiro Oda finally closes several long-standing mysteries with plot points that continue to influence the present storyline.
For the first time in the series, readers learn the complete truth behind Rocks D. Xebec, bringing his saga to a definitive end after decades of theories and speculation.
Chapter 1166 confirms that Rocks is officially dead, and the surprising figure responsible for the finishing strike is Figarland Garling.
Although Rocks had already taken devastating damage from both Garp and Roger, his downfall came when Garling delivered a cold, calculated attack while he was already defeated.

The aftermath is just as shocking: God Valley sinks into the sea, fulfilling the previous order issued by Imu to erase the island from existence.
How the island was destroyed remains unclear, but the consequences immediately ripple across the world and drastically shift the global balance of power.

Another major revelation surfaces when Rocks shares his ultimate ambition — to become the King of the World.
This ambition mirrors themes surrounding ancient rulers and deepens the long-observed parallels between Rocks and Blackbeard, two men who inherited the desire to stand above the world.

Chapter 1166 also includes a historic moment long awaited by fans: Roger discovers baby Shanks inside a treasure chest.
Although brief, the scene cements Shanks’ mysterious origins and highlights how deeply his past is rooted in the God Valley incident.
