Blue Beginnings
This unicycle riding swordsman was an early antagonist to Zoro, and from this blue.
Cabaji, from the East Blue
The man who coined the phrase this category is named after, right before getting defeated by a superior Devil Fruit
Who is Kaido
Okay, let's get the obvious out of the way. One of the Straw Hats witnessed this event first hand, before joining the crew.
Ohara's Buster Call
This Yonko could've ended two catastrophe's in one day for both Pirates and Marines alike, but was...late.
Who is Shanks?
Apparently, all Vice Admirals have Haki, which would be news for this antagonist to Luffy in the midpoint of the series.
Who is Smoker?
The navigator for a powerful Yonko pirate used to work on the other side of the law in this Blue.
Lafitte in the West Blue
This character was about to capture the Straw Hats, when he was hit with haki emanating from miles away, causing fans to dub this haki as such:
Ryokugyu, Wifi Haki
Critics of either figure may harken comparisons to the other, after all, did you really think your invention of war would not be used?
Who is Vegapunk or Oppenheimer?
This Marine has probably gotten away with too much, or has let too much get away from him, like at one midpoint of the Grandline.
Who is Kizaru?
This powerful foe surely should've had some plan or rebuttal for Luffy's counter to his abilities, I guess he never ran into Haki.
Who is Crocodile?
Both this character and her sister hail from the North Blue before joining up with the Doflamingo Pirates
Monet and Sugar
It was in this fight that Luffy unlocked this ability to "see" into the future, surpassing the ability of his opponent, which was their speciality.
Katakuri, Observation Haki
A warcrime that only the audience was a witness to, on Marineford
What is Akainu killing deserters on Marineford?
This conflicted Marine could've carried out the wishes of his superiors multiple times but chose not to before the timeskip, hinting at his future change in allegiance.
Who is Aokiji?
Recent chapters have made this classic powerscaling issue into an intentional sacrifice.
Shanks losing his arm to the Sea-King
This Admiral hails from the South Blue, surprising given his ability, you'd think maybe the East?
Sengoku
Perhaps the creator of this new type of Haki, forced a retreat and saved his friends years after his supposed defeat.
Wifi Haki, JoyBoy.
Sure they were in breach of contract, but collective punishment is a GIANT no no.
Imu's control and domination of all of Elbaf.
This character struggled like everyone else when caught in a cage, but...he shouldn't.
It appears 3rd can equal 1st, at least in this circumstance.
Vista vs Mihawk ending in a stalemate
You'd think given recent information, this would change their "origin" but this enemy of Kaidou is from this blue.
Gecko Moria
While most have to use this ability consciously, this character was the first user to manifest Haki in a new patter while casually blocking an attack unconsciously
Big Mom and her passive Armament Haki
This action, regardless of outcome or intent destroyed thousands of lives without a tear being shed.
What is Doflamingo's SMILE operation?
This character multiple times didn't do what was either expected of him, nor what they wanted to do. What a bum, pick a side.
Who is Garp?
Fans are hoping that the circumstances of the fight led to his performance, and not just his lack of power when fighting a cartoon kaiju on Science Island
Admiral Kizaru losing to one punch from Luffy on Egghead Island
