As the final battle in One Piece approaches, the intricate connections of this conflict are becoming increasingly difficult to avoid. On one side stands the World Government, which has sown seeds of destruction and oppression for over 800 years. On the other, the warriors fighting for freedom and liberation from the oppressive regime.
However, many characters from both sides do not entirely align with the interests of their respective factions. As a result, it is certain that numerous Marines and soldiers from the World Government will switch sides. In this article, we will explore the most likely candidates who may defect to the Straw Hat Pirates during the final battle.
Fujitora and Kizaru: Potential Defectors to the Straw Hat Pirates

After the timeskip, many changes occurred within the World Government, most notably the resignation of Kuzan and the promotion of Sakazuki to the top position, leading to a two-tiered leadership structure. One of the prominent figures is Fujitora, who notably appeared in Dressrosa. He is known for his sense of justice and advocacy for fairness. Considering his contrasting views with Akainu and his methods, it is highly likely Fujitora will eventually join forces with the heroes during the final battle.

Kizaru still holds the position of Admiral after the timeskip, often presenting himself as a carefree and intimidating figure. However, the Egghead arc has shed light on his character, revealing his reluctance when ordered to eliminate Dr. Vegapunk and destroy his laboratory. Moreover, he directly assisted Luffy during the Gear 5 state to fight against Saturn and himself. Following setbacks, Kizaru’s potential departure from Sakazuki further fuels speculation that he may switch allegiances in the future.
Koby and SWORD: Actions Driven by Inner Convictions

From the very first chapter of the series, the character Koby has indicated what it means to be a Marine. After Luffy set out to become the Pirate King, Koby has gone through rigorous training to become a Marine under the command of Garp, who instilled in him values similar to those of a true Marine hero. Due to the circumstances, Koby has developed a connection with the World Government after witnessing the extreme conditions at Marineford.
After the war, Koby joined SWORD, a special tactical unit of the Marines. Although part of the World Government, SWORD members operate independently, not needing to go through any higher ranks. Given that SWORD members are typically elite soldiers with noble intentions, they are likely to recognize the oppressive nature of the World Government during the final battle, prompting them to ally with Luffy.
Garp and Sengoku: Legendary Marines Who May “Switch Sides”

When discussing the legendary Marines in One Piece, no one is more significant than Garp and Sengoku. Garp is a unique figure, having placed the World Government above his own family multiple times. However, after the Marineford war, his relationship with the Celestial Dragons has deteriorated, and it’s likely he will side with Luffy during the final battle.
Similarly, Sengoku is known as one of the most brilliant Marines, akin to Garp in placing duty above personal interests. However, his relationship with Corazon and the current state of Sengoku has led many to believe he might also join the heroes in the final battle. While he may not confront them directly, Sengoku’s wisdom is likely to differ significantly from the core values of the World Government.
