In the vast and complex world of One Piece, the World Government stands as a pinnacle of power, maintaining authority and declaring the maintenance of global order and justice. However, hidden beneath the surface are dark corners, mysteries, and corruption that could lead anyone to question the true nature of this organization. Over time, many characters have witnessed or experienced events that shake their faith in the Government, and the backdrop continues to grow increasingly clear.
1. Borsalino (Kizaru)

Borsalino, also known as Kizaru, is an Admiral of the Navy with the formidable power of the Pika Pika no Mi, making him one of the core pillars of the World Government. However, deep within this seemingly invincible figure lies a troubling similarity to others. Kizaru is often forced to confront the actions and intentions of the Government, especially in relation to important allies like Sentomaru and the scientific community at Egghead, potentially causing him to doubt the integrity of the higher-ups.
Can someone as steadfast in their duties as Kizaru come to a decisive conclusion regarding his fate? The answer may lie in the limited scope of information available, where even a devoted soldier can falter. If Kizaru realizes that the Government’s actions contradict the fundamental values he believes in, it could lead to a significant shift.
2. Smoker

Vice Admiral Smoker, wielding the Moku Moku no Mi, has always been a complex character. His pursuit of Luffy is not just about loyalty to the Government but also stems from his personal beliefs in justice and law. Smoker has witnessed the Government’s corruption and the heinous actions taken, particularly during events in Alabasta and Punk Hazard.
The Government’s attempts to conceal the truth about their cruel experiments and dark schemes have led Smoker to question the integrity of this organization. Should he uncover even more horrifying secrets, there’s a chance he might break free from the shackles of the Navy to pursue what he believes is right, unbound by the rules that bind him.
3. Issho (Fujitora)

Admiral Fujitora, despite being blind, possesses immense power through the Zushi Zushi no Mi. He is a character with a compassionate heart and always prioritizes the welfare of the people. Witnessing the struggles that the citizens endure due to the oppressive nature of the Government has led Fujitora to have serious doubts about the organization he serves.
His actions, including publicly apologizing to the people of Dressrosa on behalf of the Government, clearly demonstrate his discontent with the organization’s stance. If Fujitora continues to uncover the Government’s misdeeds and the injustices they perpetrate, especially regarding hidden secrets, he may very well decide to turn against them.
4. Koby

From a timid boy captured by Alvida, Koby has grown under the mentorship of Garp to become a promising Marine officer. However, Koby’s career is not without its challenges. Witnessing the destructive acts of the Navy and the moral dilemmas faced by the organization can plant seeds of doubt in his mind.
With his integrity and moral compass, Koby could face a crucial moment where he has to choose between following orders that conflict with his beliefs or standing up for what he thinks is right. His strong character development indicates that he might very well make a bold decision to uphold justice.
5. Sengoku

Former Fleet Admiral Sengoku, who possesses the Hito Hito no Mi, Model: Daibutsu, is one of the individuals holding significant secrets within the World Government. With his intelligence and broad vision, Sengoku certainly recognizes the deeper issues within the organization that he once led.
Sengoku’s resignation as Fleet Admiral could suggest not only a relinquishment of power but also a loss of faith in the Government. If one day Sengoku decides to expose the secrets he knows, it could lead to significant upheaval within the world of One Piece.
6. Monkey D. Garp

Vice Admiral Garp, known as the “Hero of the Marines,” is a legendary figure with extraordinary strength. However, he maintains a stance that is quite dismissive towards the Government’s dealings, particularly regarding the injustices and corruption within the World Government. Garp’s repeated refusals to accept promotion to higher ranks often stem from his disdain for the corruption he sees.
With his relationships with his son Dragon and grandson Luffy, Garp stands as a direct opposition to the Government, and it is not out of the question that he may still choose to defy them when the time is ripe. The consequences of a legendary figure like Garp betraying the Government could severely impact the reputation of the World Government.
