Finally got around to do this. Here goes.
Zoro:
-Shishi Sonson:
1) A technique of Zoro's that specializes in cutting down others, with its cutting ability allowing him to cut even through iron (鉄). Because it is called "Iai", his swordsmanship is lightning fast (電光石火). One will be unable to see the flash of his katana, let alone the whole thing.
2) A special type of Iai where he places all of his strength into one sword and unleashes it. By sensing his opponent's "breath", he can determine the speed, power, and angle of where he should cut at, drawing his sword at great speeds (神速) to cut through iron (鉄)!!
-Reactive Power:
Zorro's style is to use his three swords to knock down enemies that stand in his way and proceed onwards ahead! Zorro was once defeated when he challenged "Hawk-Eye" Mihawk, and has since then vowed to never lose to the swordsmen again, gaining new power (強さ) every time he defeated a strong enemy, believing this is the only way to reach the "World's Strongest".
-Information Analysis:
Although Zoro often fights alone, he has developed combination attacks many times with his friends and due to his superior abilities as a fighter, he is able to quickly analyze the strengths of his friends and enemies to create effective coordination!!
Mihawk:
-Attack Reflection(?):
Can create immense destructive power with just a single swing of the large sword on his back. On the other hand, he skillfully uses both "hard and soft" swordsmanship such as parrying his opponent's attacks.
-Yoru's "unparalleled hardness":
Mihawk's favorite sword, one of the "Twelve Supreme Graded Swords". It is a black blade of unparalleled (比類なき) hardness.
Haki:
1) By directing one's Haki (覇気) all around them, one can grasp the number and location of those around them that are out of sight. With increased skill and accuracy, one can even see how powerful their opponent is.
2) Busoshoku (武装色) is Haki that strengthens one's offense and defense like armor. With it, it can defend them against a Devil Fruit users (悪魔の実) attacks while also allowing them to potentially attack back!
3) The basic application of Haki is to protect oneself from enemy attacks by spreading the Haki all over the body. This can enable them to block physical attacks from weapons as well as those from Devil Fruits!!
Jozu:
To suplex a giant block of ice!! His instantaneous power and arm strength are top class.
Kizaru/Borsalino (?):
With an effective ability over movement and evasion, only a skilled Haki user can stop someone in a single move.
Shanks:
One of the "Four Emperors" who rule over the New World. Once an apprentice of the Roger Pirates, he later fought against "Hawk-Eyes" and eventually grew to be an equal to "Whitebeard", creating countless legends of the sea as "Red-hair". But despite his fame, there were no other pirates who embodies freedom like him. If we were to define the "Pirate King" as "the freest man on the seas", Shanks would be the closest thing to that title.
Chinjao:
A legendary pirate who once crossed with Roger and Garp. He was once feared as "Chinjao the Drill" (錐のチンジャオ) due to his powerful head in which he draws out his Hasshoken "Kiryu Kirikugi" (八衝拳 "錐龍錐釘"). He retired from the Pirate Business after Garp shattered his head 30 years ago, putting all of his attention into training his successor. He confirmed his successor in his grandson Sai after the battle with the Donquixote Pirates in Dressrosa, acknowledging his true strength and having him inherit Hasshoken and the full might of his army.
Cracker:
[Famed Sword Pretzel]
A long sword with excellent cutting ability. By cladding his sword with his Haki, he can harm and wound Luffy's arm which was strengthened further by Busoshoku Haki.
Oven:
[Robust Body (頑強な肉体)]
As shown by immediately standing up after being run over by Bege's ship, the robustness of his body inherited by Big Mom is the best among his siblings.
Weevil:
A member of the "Seven Warlords of the Sea" who claims to be the biological son of Edward Newgate, former "Four Emporer" Whitebeard. He acts by his emotions but obediently follows the suggestions of his mother, Bakkin. His blood ties to Whitebeard are unknown but the power of his naginata, which he wields with his abnormally developed arms, is similar to Whitebeard's prior to his illness, boasting overwhelming strength that even Admiral Kizaru (大将・黄猿) takes notice of.
