As the main character of One Piece, Luffy faces increasingly powerful foes in the series’ climactic saga. With each new challenge, the strength of his adversaries escalates, underscoring Luffy’s urgent need to enhance his abilities. His current form, Gear 5—an astonishing manifestation of his Devil Fruit powers, previously known as the Gomu Gomu no Mi but now identified as the Hito Hito no Mi, Model: Nika—allows him significant strength. Nevertheless, there is speculation that his transformative potential is far from exhausted, hinting at an even greater power yet to be revealed by Oda.

Luffy’s Haki Needs Some Improvement


During the Wano arc, Luffy unlocked his Gear 5 form, an incredible power that enabled him to defeat Kaido. However, Gear 5 is not the pinnacle of Luffy’s capabilities. As he confronts progressively more formidable opponents, he cannot rely solely on this form. Oda hints at Luffy achieving an ultimate power related to Haki, specifically an advanced form of Conqueror’s Haki.
Haki plays a crucial role in One Piece, often regarded as the ultimate power. While Devil Fruits grant extraordinary abilities, to truly dominate, mastery of Haki is essential. Fans have witnessed the remarkable abilities of Joy Boy’s Haki during the Egghead arc, and to triumph over his strongest rivals, Luffy will need to not only reach but also eclipse this level of Haki.

Gaban’s Role in Training

Luffy has undergone significant training throughout his journey, with notable mentorship from Dark King Rayleigh, the former right-hand man of Gol D. Roger. His two years of training during the time skip under Rayleigh laid a strong foundation. However, a new character, Scopper Gaban, Roger’s left hand, has emerged to offer Luffy advanced training, particularly in mastering Haki.
Gaban demonstrates exceptional Haki abilities himself, having shown impressive power against the Holy Knights. His guidance is set to propel Luffy into a new realm of Haki mastery, which will further develop in the heat of battle.
