After months of fan speculation about the Forest God mentioned in the ancient Harley text, One Piece chapter 1188 delivers a series of clues that make this theory more convincing than ever. Based on Eiichiro Oda’s latest reveals, Nerona Imu is very likely the Forest God, the deity who changed world history during the Void Century.
Chapter 1188 reveals Imu’s terrifying power

The highlight of chapter 1188 is the battle between Monkey D. Luffy and Nerona Imu on Elbaf. Even though Luffy enters the fight fully energized after several chapters of recovery and unleashing his full Gear 5 and advanced Haki, he is completely outmatched.
Notably, Imu unleashes a new technique called Blade of Nothingness: Vohu. In the blink of an eye, the World King closes the distance at a speed too fast for Gear 5 to react, then pierces Luffy’s body with the void sword.
Imu even bluntly declares that Luffy is “too weak to be Joy Boy,” emphasizing the vast power gap between them.
Destructive power over the forest draws fan attention

What intrigues fans even more isn’t just the finishing blow on Luffy, but the effect that comes with the Vohu sword. As Imu summons the blade using Omen power, all the vegetation around the Adam tree instantly withers and dies. In moments, an entire forest seems drained of life.
This isn’t the first time Imu shows a strange influence over plants. In chapter 1179, when Imu appears on Elbaf, the surrounding forest changes, with tree trunks growing eerie faces as if alive. This phenomenon disappears once Imu leaves.
These two details lead many to believe Imu not only possesses destructive strength but also a unique ability to manipulate or control forests.
All clues point to the Forest God in the Harley text

This theory gains more ground when compared to the ancient Harley text introduced by Oda in chapter 1138. Regarding the Second World, Harley describes: “After ‘breath’ appeared in the Void, the Forest God awakened. The Forest God then unleashed demons upon the world. The battle between the Sun God, Sea God, and other races began from here.”
Many details match surprisingly well with Imu’s recent actions. Imu’s Blade of Nothingness literally means “Void,” echoing the opening line in Harley. The ability to wither forests also directly connects to the title Forest God.
The most notable point is the Harley text’s mention that the Forest God “unleashed demons.” In the current storyline, Imu is the source of power behind many demonic forces such as the Five Elders, the Holy Knights, and victims transformed by Domi Reversi. All possess demonic abilities originating from Imu.
If Harley is truly describing Imu, then the Forest God releasing demons perfectly aligns with Imu creating a demon army to serve the World Government. This also fuels speculation that Imu holds the Forest God Devil Fruit, a power surpassing all known Logia, Zoan, or Paramecia types.
Could the Forest God be the founder of the World Government?
If Imu is the Forest God, many mysteries in One Piece fall into place. After the war with the Ancient Kingdom and Joy Boy, 20 allied kingdoms formed the World Government.
Most descendants of these 20 kings still reside in the Holy Land Marie Geoise. Among them are the Five Elders and Holy Knights, figures with demonic powers directly linked to Imu.
This leads many to believe Imu granted powers to these allies, building the ruling system that has lasted 800 years. If this theory holds, the Forest God is not just a legendary deity from Harley’s tale but the mastermind behind the World Government’s creation.
Eiichiro Oda has yet to confirm Imu as the Forest God directly, but the details in chapter 1188 make this theory increasingly compelling. From forest manipulation and demon creation to strong ties with the Harley text, all signs point to the same answer.
