Techniques Busoshoku: Koka, Atama Buso, Gear Second Buso Monkey D Luffy

Techniques Monkey D Luffy is Busoshoku: Koka, Atama Buso, Gear Second Buso.

Busoshoku: Koka

Busoshoku: Koka (武装色 硬化 Busō-shoku: Kōka, literally meaning: "Color of Armaments: Hardening"): Luffy uses Busoshoku Haki to harden his body (or parts of it). It was used for the first time against the Kraken in conjunction with Gear Third to harden his enlarged arm to the point of it attaining a completely dark and shiny appearance, in order to use his Gomu Gomu no Elephant Gun. In the FUNimation subs, it is called Armament; Hardening.

Atama Buso

Atama Buso (頭武装 Atama Busō, literally meaning "Head Armament"): Luffy imbues his forehead with Busoshoku Haki to harden it. This is first used in preparation for a Gomu Gomu no Kane against the Iron Shell Squadron. In the FUNimation subs, it is called Head; Hardening.

Gear Second Buso

Gear Second Buso (ギア２（セカンド）武装 Gia Sekando Busō, literally meaning "Gear Second Armament"): Luffy imbues his fist with Busoshoku Haki while under the effect of Gear Second to harden it, which also seems to have the added effect of igniting it. It was first used in preparation for Gomu Gomu no Red Hawk against Hody Jones.

Early Monkey D Luffy One Piece

When drawing One Piece, Eiichiro Oda was heavily influenced by the manga Dragon Ball, and had the series in mind when designing his characters. Oda has said that when he was creating Luffy, he was thinking about "manliness", because Dragon Ball had already done all the things that a child could possibly be happy about.

Luffy was first featured as the main protagonist in the first pilot of One Piece Romance Dawn V.1 in the Shonen Jump specials showcasting upcoming artists, about a year and a half before One Piece began. He would remain as the main protagonist in the second release of Romance Dawn, Romance Dawn V.2 (featured in Weekly Shonen Jump magazine itself) and the final version Romance Dawn V.3.

Early Monkey D Luffy One Piece

Luffy's character changed throughout all three versions of Romance Dawn. Starting from Romance Dawn version 1, Luffy was much smarter than his final incarnation and while he had the power of the Devil Fruit he did not seem to have any named attacks. He claimed to be a candidate for pirate and a Peace Maine type of pirate. His background story was near enough identical to the final story released with Romance Dawn version 3, with a number of noteworthy differences. The major difference being that Higuma the Bear was absent from the story in this version. Another minor difference was that Shanks' arm was bitten off by a shark instead of a Sea King. In Romance Dawn V.1 there was also a panel that featured a Luffy as captain of his own crew. This is the only time a older version of Luffy has been drawn by Oda in regard to the One Piece storyline.

Version 2 of Romance Dawn featured a Luffy closer to the final version then Romance Dawn version 1. He now had a named attack (though it featured a different naming scheme to the final version) and lacked the intelligence he displayed in Romance Dawn version 1, however, it is arguable that he was less intelligent than his final design overall. His story, though still featured him eating the Devil Fruit, did not feature Shanks and instead Luffy got both his hat and the Devil fruit he ate from his grandfather. Luffy remained a Peace Maine type of pirate in this version and was still promoting himself as a candidate for a pirate while seeking to join up with a crew.

In both versions, Luffy was missing the scar under his left eye and he had a slightly different jolly roger. Apart from this the only difference in Luffy's overall appearance was the adaptation to suit the drawing style of each Romance Dawn. The most note worthy change from each version was of Young Luffy, whose head and body shape, though remained roughly the same, was different enough to notice.
