After consuming the Gomu Gomu no Mi, Luffy’s body became like rubber, giving him the ability to stretch and attack long distances. Having undergone intense training for over ten years, Luffy is now able to supplement his stretching powers with immense strength, agility, and creativity in combat.
He has also developed several peculiar methods of combat as time passed, adapting new forms by manipulating his elastic body(Gear 2 and Gear 3) and using Haki in conjunction with the fruit’s powers (Gear 4).
Luffy is able to use Haoshoku Haki, a type of Haki possessed only by one in a million people. Luffy used this ability several times in the series, as it was the type of Haki that manifested the earliest.
Since training with Silvers Rayleigh, he have gained incredible proficiency in Kenbunshoku Haki, allowing him to tell what an opponent intends to do. After pushing his Kenbunshoku Haki to its peak during his fight against Katakuri, Luffy gained the ability to see into the future to a limited extent. Katakuri himself even noticed that Luffy’s level of Kenbunshoku Haki was reaching his own.
Luffy has advanced his Busoshoku Haki, allowing him to project it from his palm as well as progress even further by destroying objects he touches from the inside.
