A One Piece gym is celebrating its second anniversary, and it decided to do something special: a Luffy bodybuilding contest.

Joy Boy's powerful Haki was showcased, surpassing all others in the story so far, leaving only a few who can rival it. Luffy, Whitebeard, Roger, and Shanks all possess advanced Haki abilities ...

Although he never stands out on the battlefield as much as characters like Luffy and Zoro ... Franky learning the secrets of Armament Haki would be an amazing choice for the character.
