The final saga of One Piece begins with the Egghead arc, where the Straw Hat Pirates confront the enigmatic Imu and prepare to venture to Elbaf. The Straw Hat crew must also face a new formidable foe. As the series intensifies, many members of the Straw Hat crew have yet to master Haki, which raises concerns and can impact their performance. However, with Nami, the Straw Hat crew could potentially achieve significant success in the Final Saga.
Nami’s Vital Role in the Story

Nami is one of the earliest members to join Luffy on his adventure to explore the Grand Line and search for the legendary treasure, One Piece. From the very beginning of the story, Nami has played a crucial role, even if her abilities are not as prominent as those of other crew members such as Luffy, Zoro, or Sanji.
Nami serves as the navigator of the Straw Hat Pirates. The navigator’s role is critical when sailing through the Grand Line, a place full of unpredictability and danger, where only the best navigators can safely lead a ship from one island to another.
Despite not boasting immense physical strength, Nami has proven exceptionally skilled over the two years that have passed. She possesses crucial knowledge for battles in the New World. However, one aspect that many overlook is that Nami holds the key to countering the significant threats posed by the Marines and notable characters like Imu and the members of the Gorosei.
Nami’s Importance in Countering the Gorosei

Nami has already established her importance, but she will play an even more significant role in the Final Saga of One Piece. As many fans have speculated, the characters who have made a pact with Imu may possess extraordinary abilities, one of which is the ability to counter. With this power, a character cannot be killed and can potentially resurrect indefinitely. Nevertheless, even such immense power has its limits, as seen in the Elbaf arc. Gaban has demonstrated that the ability to counter can be surpassed by using a higher form of Haki.
However, not many characters can utilize advanced Conqueror’s Haki, let alone mention High-Level Conqueror’s Haki. This is precisely where Nami can shine. During her two years in Weatheria, Nami learned to harness Wind Knots, and as observed in Egghead, these knots can store Haki.
Joy Boy knew how to use these wind knots and store his most potent Haki within them, allowing Emeth to evade Imu and confront the Marines. Nami could store Luffy’s Conqueror’s Haki within these wind knots and distribute it to those who cannot withstand the onslaught of Imu’s Conqueror’s Haki on their own. She will be a valuable asset in the upcoming battles and once again become a central character, just as she has done in many other arcs of One Piece.
