The One Piece world is a labyrinth of power, politics, and centuries-old conspiracies. For years, the elusive Monkey D. Dragon has been the singular figurehead of rebellion, a man with the highest bounty in the world and the leader of the Revolutionary Army, openly challenging the tyranny of the Celestial Dragons. His son, Monkey D. Luffy, carries the inherited will of freedom, a force so potent it has already shaken the foundations of the World Government. However, as the Final Saga unfolds, with recent manga revelations unveiling the enigmatic and terrifying powers of Imu, a startling new perspective emerges. While Dragon represents a direct and formidable military threat, another character embodies a deeper, more existential danger to the throne of the world. This is not about a clash of armies, but a battle for the very truth of history, and it is here that a different figure, one who controls the past, becomes Imu’s most significant and feared adversary.

The prevailing fan theory has long held that the final conflict would be a grand, three-way war between the Pirates, the Marines, and the Revolutionaries. In this scenario, Dragon, with his unparalleled charisma and strategic genius, would be Imu’s primary combatant. His ability to inspire global revolt, coupled with a yet-to-be-revealed fighting prowess that likely rivals or even surpasses his legendary father, Monkey D. Garp, paints him as the ultimate revolutionary. He is the physical embodiment of the people’s will against an oppressive regime. Yet, Imu’s true fear is not a military coup; it’s the dismantling of the carefully constructed lies that have upheld their rule for 800 years. This is where the true threat lies, and it is a character who holds the key to the Void Century’s secrets.

The Intellectual Threat: Why Knowledge Outranks Strength

While Dragon commands a powerful army, his primary objective, as revealed in the manga, has been to topple the Celestial Dragons and their political control. This is a direct assault on the system. Imu, however, operates on a much deeper level. The Empty Throne, the Poneglyphs, and the very mystery of the D. clan are not simply symbols of power—they are the core pillars of their supremacy. To defeat Imu, one must not only possess the strength to fight them but also the knowledge to expose their hidden history and strip away their divine right to rule. This is the domain of Nico Robin.

Nico Robin is the biggest threat to Imu. Her unique ability to read the Poneglyphs, a skill that the World Government has tried to erase from existence, makes her an unparalleled danger. The reason for the World Government’s brutal annihilation of Ohara was precisely to prevent this knowledge from being revealed. They didn’t fear the Ohara scholars’ physical power; they feared the truth they could uncover. Robin is the living legacy of that fear. She holds the one thing Imu cannot allow to be made public: the true history of the world and the origins of Imu’s reign.

Consider the following points that elevate Robin’s threat level above Dragon’s:

  • The Will of D. and the Ancient Kingdom: Robin has already gathered a significant amount of information about the Void Century and the Ancient Kingdom. She knows about the alliance of the twenty kingdoms and their role in the downfall of Joy Boy. Unveiling this history to the world would not just cause a revolution; it would delegitimize the World Government entirely. The moral authority of the Celestial Dragons would crumble, leaving them exposed and vulnerable. Dragon’s fight is about power; Robin’s is about legitimacy.
  • Targeted Pursuit: While Dragon is a globally wanted criminal, the World Government’s pursuit of Robin has been deeply personal and relentless since she was a child. The bounty on her head, her backstory with Ohara, and the sheer desperation with which the Marines hunted her down speak volumes about the threat she poses. It is a threat that predates the Revolutionary Army’s formation and has been a constant source of anxiety for the World Government for decades. Imu’s interest in her is explicit and terrifying.
  • The Truth is a Weapon: Imu’s power isn’t just a Devil Fruit or Haki; it’s the control of information. They have rewritten history, creating a narrative that serves their interests. Revealing the truth about the Ancient Weapons, the true identity of the D. clan, and the real reasons behind the Void Century would be a weapon far more destructive than any warship or Admiral’s attack. It would turn every citizen against the World Government from within. Dragon’s forces can only fight a war they can see; Robin’s knowledge can win a war that has been hidden from everyone for centuries.

The Interconnectedness of Fate: Luffy, Dragon, and the Final Battle

Of course, this is not to say that Monkey D. Dragon is an insignificant player. On the contrary, he is the leader of the world’s greatest opposition force and will play a pivotal role in the final war. His strategic genius will be crucial for the physical fight against the Marine forces and the God’s Knights. However, his role is likely to be that of a direct combatant, clearing the path for the real ideological confrontation. The narrative has always positioned Luffy as the one who brings a “dawn” to the world, a dawn that is not just about a change of power but the revelation of a new, truthful era. It is not a coincidence that Robin, the only one who can read the Poneglyphs, is a core member of his crew, and that her dream directly aligns with his goal of becoming the “King of the Pirates” by finding the One Piece and revealing the truth of the world. The One Piece itself, after all, is the final piece of this historical puzzle.

The ultimate showdown may see Luffy face off against Imu, but the reason for that confrontation will be driven by the truth that Robin uncovers. She provides the “why” for the final war, while Dragon and his army provide the “how.” In this grand tapestry of destiny, the man who controls the storm is a serious threat, but the woman who controls the truth of history is a far more devastating one. Imu’s greatest fear is not a man with a revolution, but a woman with a book—a book that holds the unedited, unadulterated history of the world, a history that will bring their 800-year reign to a crashing and irreversible end.
