As 2025 comes to an end, One Piece fans are left reeling from a year packed with earth-shattering revelations. From the true identity of Shanks’ brother to the long-buried truth behind the God Valley Incident, Eiichiro Oda spent the year dismantling long-standing theories and reshaping the story’s endgame. With 2026 poised to become a historic year—thanks to the anime’s seasonal format, the manga’s final stretch, live-action Season 2, and WIT Studio’s The One Piece now is the perfect time to look back at the moments that defined 2025.

1. Elbaf’s Ancient Codes: The Wall Mural and the Adam Treasure Tree

The Straw Hats’ arrival in Elbaf revealed the land of giants as a vast archive of world history. The highlight was the colossal mural carved into the Adam Treasure Tree, discovered by Franky and Ripley. The artwork depicted three eras the First, Second, and Third Worlds hinting at cyclical global conflicts and foreshadowing a looming third great war. While the inscriptions remain undeciphered, this mural cemented Elbaf as a key to understanding the past and the future.

2. The Shamrock Shock: Shanks’ Bloodline Confirmed

One of the biggest bombshells of the year was the reveal of Shamrock, the man who once met the Five Elders and Shanks’ twin brother. Despite their identical appearances, their ideologies could not be more different. This revelation confirmed Shanks’ royal lineage and his ties to the Figarland family, ending years of speculation and placing his role in the final saga under a completely new light.

3. The Return of a Legend: Scopper Gaban

After decades of mystery, Roger Pirates veteran Scopper Gaban finally returned to the spotlight. His overwhelming power was showcased when he struck down Shepherd Sommers with a Haki-infused axe, revealing a crucial truth: advanced Conqueror’s Haki can suppress the regeneration of the God’s Knights. Gaban’s words to Luffy made one thing clear—these knights are not immortal, and Imu can be defeated.

4. Imu’s Terrifying Ability: Domi Reversi

In 2025, Imu fully stepped out of the shadows. The most horrifying display of power came through Domi Reversi, an ability that turns its victims into fully controlled demonic puppets. Even legendary figures like Dorry, Broggy, and Rocks D. Xebec were affected. This power now stands as one of the greatest obstacles Luffy and his allies must overcome.

5. Rocks’ Infiltration of the Flower Room

Mary Geoise is nearly impossible to breach, yet Rocks D. Xebec did the unthinkable. During a Levely, he kidnapped five kings, clashed with Harald, and even confronted Imu directly in the Flower Room. Declaring allegiance not to the World Government but to Davy Jones, Rocks transformed from a feared pirate into a symbol of absolute rebellion.

6. The True Identity of Rocks and Blackbeard’s Lineage

Chapter 1154 delivered one of the most shocking reveals in the series: Rocks D. Xebec is the father of Marshall D. Teach, better known as Blackbeard. Even more startling, Rocks’ true name was revealed as Davy D. Xebec, a direct descendant of the legendary Davy D. Jones. This revelation redefined both Rocks’ legacy and Blackbeard’s destiny.

7. The God Valley Incident Finally Exposed

The God Valley Incident has long been One Piece’s greatest mystery, and 2025 finally brought it into the light. An eight-chapter flashback unveiled horrific truths from Shakky being kidnapped as a prize in the World Government’s brutal human hunt, to the presence of the Davy family on the island. The chaos escalated as Kaido stole the Uo Uo no Mi, Model: Seiryu, Imu possessed Saturn’s body, and Roger and Garp were forced to join forces after Rocks fell under Domi Reversi’s control.

8. Rayleigh’s Timely Rescue of Shakky

Amid the tragedy of God Valley, one warm moment stood out. When Shakky nearly fell to Sommers, Silvers Rayleigh arrived just in time, striking down the threat and saving her life. In a sea of despair, this act of loyalty and love became one of the arc’s most emotional highlights.

9. Roger and Garp vs. a Manipulated Rocks

The legendary alliance between Roger and Garp was born from tragedy. With Rocks losing himself under Imu’s manipulation, the two heroes fought not to kill him, but to stop the destruction. After their combined attack freed Rocks’ mind, Figarland Garling appeared and executed him mercilessly ending a legend in the cruelest way possible.

10. The Tragedy of King Harald and Loki’s Sacrifice

The fate of King Harald of Elbaf was finally revealed. Controlled by Imu, he slaughtered his own army, forcing his son Loki to act. By using Elbaf’s mysterious Devil Fruit to kill his father, Loki chose to bear the title of traitor and villain to protect his people’s future one of the most heartbreaking sacrifices of the year.
