The Elbaf arc has proven to be incredibly captivating, with fans eagerly witnessing the significant revelations surrounding the lore of One Piece while also being introduced to new characters. Elbaf has brought to light one of the most formidable characters in the entire storyline – Imu – and the implications of this character are indeed astonishing. As anticipated, when Luffy eventually confronts someone as powerful as Imu, he will need to be in peak condition, and fans are keen to see what kind of abilities will be displayed before this climactic battle.
While Luffy has exhibited overwhelming power through incredible abilities like Haki and Gear 5, it is clear that he will need to unlock even greater strength to counter Imu effectively. In reality, Luffy’s next power-up has already been decided by Oda, and it will be revealed soon in the current Elbaf arc.
Luffy’s Gear 5 and Haki: Still Not Enough

Fans are well aware that Luffy can utilize the tremendous power of Gear 5, but in some respects, he has been over-relying on it. However, as the story progresses, Oda consistently emphasizes that Haki is equally crucial for Luffy to surpass every opponent.
Kaido previously acknowledged Luffy’s Haki as superior, which is attributed to Luffy’s relentless training over the years. During the Wano arc, he learned to use Advanced Conqueror’s Haki more effectively, making it an indispensable part of his combat arsenal.
However, fans recognize that Advanced Conqueror’s Haki alone is not enough. This was made abundantly clear during the Egghead arc, where Luffy’s battle against Saturn demonstrated that he still requires additional strength to contend with formidable foes like Saturn and Imu. The greatest threat currently is the unpredictability of this group, and Luffy needs a new power boost to face them.
Luffy Will Soon Learn How to Counteract Unpredictability

In the Egghead arc, Luffy was forced to hold back against enemies like Saturn because he couldn’t unleash significant damage on them. However, in Elbaf, things will be different. He cannot afford to hold back on Elbaf, which signifies that Luffy will learn to overcome unpredictability right here, and this will be a key moment for his next power-up.
Of course, Luffy is likely to seek out ways to discover this potential. Scopper Gaban, the left-hand man of Pirate King Gol D. Roger, has provided insights into overcoming unpredictability during their long conflicts. Chopper might even follow him to uncover the secrets behind this hidden potential.
It’s certain that the Straw Hat crew will learn about the secrets of the Celestial Dragons and how to counteract unpredictability. Above all, Luffy must master this new ability, and once he achieves it, he could potentially counter any attacks from formidable foes like Saturn. Moreover, Luffy may even engage in battle against the powerful Imu, who is currently manipulating the fabric of the world.
Luffy’s New Power Will Be Monumental

After learning how to counteract unpredictability from Saturn and the Celestial Dragons, Luffy is set to reach a completely new level of power. Fans understand that he has already reached the level of an Emperor, but this new ability will elevate him even further, bringing him closer to legendary figures like Shanks and Roger.
