15 Things You Didn’t Know About Haki In ‘One Piece’

Vote up the most interesting facts about Haki.

Devil Fruits and weapons aren't the only way to fight in the One Piece world. There's also Haki, a complex set of moves that involves manipulating one's spiritual energy to produce a variety of effects. There are three types: Haoshoku Haki, which lets the user control another person's will, Busoshoku Haki which lets the user harness their spiritual energy for defensive and offensive purposes, and Kenbunshoku Haki, which imbues sensory abilities. If you're a One Piece fan, you most likely knew all of that, but there might be some things you didn't know about Haki.

Haki is a Japanese term that likely derives from the Chinese concept of qi. But it's also the name of a famous Scandinavian sea-king in Norse mythology. Also, did you know that Shanks and Silvers Rayleigh are potentially capable of knocking out 100,000 people at once with their Haki?

    How Many Men Could Shanks And Silvers Rayleigh Take Down With Haki?

    A fan noted that when Luffy used Haoshoku Haki, he was able to eliminate about 50,000 men at once. They wondered what Shanks or Silvers Rayleigh might be able to do that under the same circumstances. Oda had a detailed explanation:

    "In exactly the same place and exact same situation as Luffy, Shanks or Rayleigh may have been capable of knocking out all 100,000. In a different setting, you can't really compare just by asking 'how many people'. Being able to knock an enemy out with haki depends entirely on having an overwhelming power gap between the two. In Luffy's case the point is the number of people that were so weak that they were not even worth him fighting. If there were 100,000 to-some-extent-strong-willed pirates before him, it's possible that he wouldn't even be able to knock out a single one. On a related note, as one's proficiency with haoshoku advances, it's even possible to target a few people in a crowd to NOT knock out."

    Busoshoku Haki Is The Most Commonly Used Variety

    While all three forms of Haki have plenty of users, the most commonly used variety by far is Busoshoku Haki. While the reason for this has not been confirmed, it seems likely that it's because Busoshoku Haki has the most obvious application in fights.

    Busoshoku: Koka Has A Luffy-Themed Name

    Busoshoku: Koka is a move that lets the user coat a selected body part with Haki, hardening it and increasing its defensive capacity. While anyone who uses this type of Haki can perform this basic function, the name itself is connected with Luffy specifically.

    Koka translates to vulcanization, which is the process of hardening rubber.

    Haki Impacts People Differently In The Anime And The Manga

    In the anime, a person who gets hit with Haoshoku Haki usually passes out. In the manga, it's a little more dramatic. Instead of simply losing consciousness, they foam at the mouth.

    Haki Is The Name Of A Scandinavian Sea-King

    Haki is a Japanese term, but it's also the name of a Scandinavian sea-king from Norse Mythology. Sea-king is a title bestowed on high-ranking Viking chieftains. Haki was known for his exceptional cruelty and extensive conquests. 

    We don't know whether Oda intended to reference this Haki, but considering the sea-faring nature of the reference, it seems possible.

    Busoshoku Haki Is A Lot Like Tekkai

    Busoshoku Haki isn't the only way to harden ones' body. You can also use Tekkai, a Rokushiki technique that's used by the CP9. Busoshoku Haki requires willpower and life force, while Tekkai requires raw physical power. The other difference is that both Tekkai and Busoshoku Haki have unique weaknesses.

    While Tekkai is great for defense, the user is largely immobile and may be unable to strike their opponents. Busoshoku Haki doesn't have this problem, but it can drain the user's energy after too much use.
