One Piece fans know that the Straw Hat Crew has three members who are quite respected, namely Monkey D Luffy, Roronoa Zoro, and Sanji Vinsmoke, who are collectively known as the Monster Trio. Although both Zoro and Sanji are known for being the most loyal members of the crew, fans also tend to compare their strengths.
As two of the strongest members of the Straw Hat Crew, Zoro and Sanji are just as popular as their captain, Luffy. However, they both have different roles and responsibilities within the crew. Seiichiro Oda intentionally depicted them with unique characteristics that complement each other.
Sanji is often portrayed as a protector. He frequently engages in duels to protect his fellow crew members, such as when he fought against Mr. 2 to protect Vivi in Alabasta, Jyabura to replace Usopp in Enies Lobby, and Absalom to protect Nami in Thriller Bark. His recent fight with Seraphim Jinbe in Wano further showcases his protective nature.
On the other hand, Zoro is depicted as a fighter who always strives to win and increase his strength. He is constantly pursuing Mihawk to increase his power and skill in swordfighting. His words and actions during battles clearly reflect his determination to win, such as when he vowed to defeat Ryuma to obtain Shusui or when he promised to never lose again after his defeat by Mihawk.
However, both Zoro and Sanji are equally strong in their own unique ways. Comparing their strengths would be inappropriate as they have different roles and characteristics that complement each other. Sanji acts as a mentor and a strategist who analyzes the situation to find the best course of action. In contrast, Zoro is a no-nonsense swordsman who initiates attacks and takes charge in battles.
Their distinctive roles and characteristics make them both indispensable members of the crew, and they could be considered as the sword and shield of Monkey D Luffy. In the absence of their captain, they are capable of leading the crew in their own way. Sanji is perceived as a mentor-like figure and a protector, while Zoro is the initiator who prefers to take direct action.
In conclusion, Zoro and Sanji are two of the strongest members of the Straw Hat Crew with different roles and characteristics that complement each other. They both have their unique strengths that make them indispensable members of the crew, and their leadership qualities are evident in their own way.
