In the World of the Sea: I Revived Rocks

At the Battle of God Valley, the Navy hero Garp appeared out of nowhere and became the Navy's standard-bearer.

But those who knew the truth understood that Garp and Roger had actually joined forces to defeat the Rocks Pirates at God Valley.

What really happened? The Rocks Pirates included several of today's Four Emperors, Whitebeard, Big Mom, and Kaido, along with other famous pirates.

How could a pirate crew like that have lost?

Ten years later, while salvaging the wreckage of a battle, the Navy recovered a frozen corpse from the ocean floor.

They then sent the body to Vegapunk's research center.
