3 – SILVERS RAYLEIGH
Rayleigh has an extremely high level of skill in Busoshoku Haki, allowing him to effectively bypass the powers of a Devil Fruit user and touching the “substantial body” beneath whatever protection the fruit provides as seen when he used Busoshoku Haki to kick and redirect an attack from Admiral Kizaru. Rayleigh’s immense proficiency in Busoushoku Haki allows him to use it for devastating offense.
Rayleigh can utilize an advanced application of Busoshoku which enables him to emit his Haki a short distance without a medium. He is also able to use a high-grade version of this technique, where Rayleigh can channel his Haki into his opponent, letting him destroy them from the inside out, which he first used to destroy Camie’s collar.
2 – MONKEY D. GARP
He demonstrates extremely proficient skill in Busoshoku Haki, being able to injure Luffy several times, bypassing his rubber body. He could harden his fist and turned it obsidian black, allowing him to counter and even crush Chinjao’s Haki-enhanced drill shaped head 30 years ago, proving his superior mastery compared to Chinjao, who himself is a powerful expert Busoushoku Haki user in his own right. During the Battle of Marineford, he managed to punch and hurt Marco despite the latter being in his regenerative phoenix form.
1 – GOL D. ROGER / WHITEBEARD
Whitebeard possessed an immense mastery of Busoshoku Haki, 30 years prior in his prime, his Busoshoku Haki coated Murakumogiri, was powerful enough to defend against both Enma and Ame no Habakiri, 21 O Wazamono Meitos, another superior Busoshoku Haki master who had hardened them using Haki; a notable feat as Oden bisected the enormous Mountain God and Enma would later wound the nigh-indestructible Kaido. He uses Advanced Busoshoku, proving his mastery by hardening Murakumogiri to the point where a black flame-like aura as large as himself formed around its blade and emitted Haki from a short distance, causing a gigantic shock wave that spread across the island after clashing against Gol D. Roger despite their weapons not connecting.
Due to his age and worsening health, it was not as powerful compared to his prime, but he could still negate the intangibility of Logia-based Devil Fruits. During the Marineford War, Whitebeard successfully inflicted significant damage on Akainu where Marco, Vista, and Jinbe, who were highly skilled Busoshoku Haki users, failed to do so.
Roger possessed immense mastery over Busoshoku Haki. He could imbue his weapons, specifically his saber, harden it and cause a stream of black flame-like aura just as large at himself to flow out from his sword and could clash against the Murakumogiri, one of the 12 Saji O Wazamono Meito.
As a testament to his mastery, he could even overpower Kozuki Oden, who was an exceptional master of Busoshoku Haki in his own right.
Roger proved his mastery and advancement of Busoshoku Haki to where he could emit it from a short distance using his saber as a clash between him and Edward Newgate which resulted in a gigantic shock wave that spread across the island despite their weapons not coming into contact with one another.
