To be able to continue on his adventure and defeat the enemies ahead, Luffy only has one option and that is to get stronger. Luffy's Awakening, Gear 5, is powerful, but this isn’t his strongest form. Oda will eventually reveal a power that surpasses even that.

Luffy’s Ultimate Power Will Be Advanced Conqueror’s Haki

Luffy is a Great Devil Fruit User, But His Haki Needs Some Improvement

Fans know that Luffy unlocked his most powerful form during the events of the Wano arc when he took on Kaido. This form is none other than Gear 5, and it is what allowed him to finally take Kaido down.

Gear 5 is the awakening of his Devil Fruit previously known as the Gomu Gomu no Mi, now known as the Hito Hito no Mi, Model: Nika. This form allows Luffy to go above and beyond his previous powers, where the only limit is his own imagination.

Gear 5 is definitely powerful, but it won’t be Luffy’s last or ultimate ability. Luffy is fighting enemies stronger and stronger, and just Gear 5 won’t be able to cut it. Oda is still hiding Luffy’s ultimate power-up, and this ability has to do with his haki.

As many fans know, Haki is the ultimate power in One Piece. Devil Fruits are great, but one can’t be at the top without amazing Haki. Fans of the series have already seen the power of Joy Boy’s Haki during the Egghead arc, and Luffy will not only have to reach this level, but he will also have to surpass it.

This is why Luffy’s ultimate power will definitely be related to Haki, specifically, Advanced Conqueror’s Haki. This Haki could counter the immortality showcased by the Five Elders and Holy Knights, and could even be combined with his Gear 5 form, similar to how his Gear 4 form uses Armament Haki coating.

Gaban Is Here To Train Him

Rayleigh trained Luffy for 2 years during the time skip, however, a new teacher has appeared in Elbaf, and this time, he will teach Luffy even more about Haki.
