PORTGAS D. ACE
Portgas D. Ace was the 2nd Division Commander of the Whitebeard Pirates and one-time captain of the Spade Pirates.
Ace possessed immense physical strength which was supplemented by his extraordinary fighting skills.
He ate the Devil Fruit Mera Mera no Mi, a Logia-type fruit that allowed him to become the element of fire and control the flames from his body.
Ace’s Haki had been described by Shanks and Benn Beckman to be fiery in nature, to the point that Ace’s very presence was able to stop blizzards on an island for as long as he was there. As such, when he turned up on Drum Island, no snow fell at all on the island for an entire day.
Ace possessed Haoshoku Haki, which he initially had no conscious control over. He first demonstrated the ability at 10 years of age, anyway he has never been seen using Haki apart from during his childhood. He also possessed Busoshoku and Kenbunshoku Haki.
EUSTASS KID
Eustass Kid is the captain of the Kid Pirates. Kid has immense strength and resilience and according to Kaido, he can use Haoshoku Haki.
Kid ate the Jiki Jiki no Mi, a Paramecia-type Devil Fruit that enables the user to generate magnetic fields that can either attract or repel metallic objects to and from their body as they please.
By using repulsion, he can deflect metal projectiles back to the location they came from, thus turning them back against their users.
With attraction, he can strip opponents of their weapons and bring them to their own body, rendering opponents helpless.
The fruit gives the user a sufficient degree of control over their magnetism to accumulate a large amount of metallic objects on their body and form them into specific shapes; the user can then move these masses around very fluidly.
LUCKY ROO
Lucky Roo is one of Yonko Shanks’ most important men. He’s the first person to kill someone both in the anime and the manga, by shooting a mountain bandit in the head at point blank range.
During Romance Dawn, we see one of Higuma’s men pointing a gun at Shanks’ head, then after Shanks warns him suddenly Lucky Roo appears and shoots him. Now here’s the question, how can a big man like that go there that quickly without being noticed? It is likely that he is based on Lucky Luke (a fictional cowboy -gunfighter- from the “Lucky Luke” Franco-Belgian comic book) that is known as “The man who shoots faster than his shadow”.
Lucky Roo he’s supposed to be a Haki master or, anyway, a master in something different; in particular, many speculated that he uses a technique called “Life Return”. In this case, Lucky Roo eats so much because he is storing energy for a battle. Life Return gives him the ability to control his body; this can be used to turn fat into muscle, or just turn fat into energy.
KUZAN
Kuzan is a former Marine admiral. He was nominated by Sengoku for the position of fleet admiral but after losing the position to Sakazuki, he resigned from the Marines and affiliated himself with the Blackbeard Pirates.
Kuzan has the powers of the Hie Hie no Mi, a Logia Devil Fruit that allows him to control, create, and become ice. In battle, he uses his ice powers to disable and immobilize enemies, freezing their bodies solid just by touching them, and threatening to shatter their fragile forms. This fruit is so powerful that his usage of it during his ten day battle with Akainu permanently changed the weather on one side of Punk Hazard, turning that side into a frozen wasteland.
Kuzan was considered to be a massive asset to the Marines, and his departure left a negative impact to their military strength. This was confirmed by the Gorosei calling him an ‘enormous power’ while discussing his affiliation with the Blackbeard Pirates, to the point of being visibly distraught while doing so.
SENGOKU
Sengoku was the fleet admiral of the Marines pre-timeskip, succeeding Kong and preceding Akainu. He was also one of the major figures along with Whitebeard, Shiki, and Monkey D. Garp during the times when Gol D. Roger was still alive, and still continues to be in the present, even after his retirement from the Marines.
Even without his Devil Fruit powers, Sengoku has great strength and speed; he is also shown to have a strong will as he was able to resist Luffy’s unconscious burst of Haoshoku Haki. Sengoku is one of a very small number of people who can use all three types of Haki: Kenbunshoku, Busoshoku, and Haoshoku.
Sengoku ate the Hito Hito no Mi, Model: Daibutsu, a rarer-than-Logia Mythical Zoan-class Devil Fruit which allows him to turn into a gigantic Daibutsu. This ability gives him a massive power boost to his already impressive strength, enough to cause the execution stand to collapse in one indirectly connecting punch, despite the combined effort of Luffy’s Gear Third and Mr. 3’s Candle Wall to absorb the attack. He can also launch an explosive shock wave with a palm thrust, enough to send a majority of the Blackbeard Pirates flying a fair distance.
