#4 – Trafalgar D. Water Law
Trafalgar Law is the captain and doctor of the Heart Pirates. He is the user of a Devil Fruit called the Ope Ope no Mi, which allows him to create a spherical territory of light blue aura. In this territory, he is capable of separating and spatially displacing anything and everything inside (including himself), referred to as that he can “operate” on anything within the spherical “operating room”. Easily among the most versatile Devil Fruits around, with his powers, Law is capable of causing mass havoc within the area he controls. Law appears to have mastered his power to such a great extent, that he can even cut through someone who completely imbued their body in Busoshoku Haki.
Ope Ope no Mi has been called the “Ultimate Devil Fruit”. Infact it has the unique power to grant another person eternal youth in exchange for the current user’s life.
Law has shown great proficiency in Busoshoku Haki. He also possesses Kenbunshoku Haki.
#3 – Eustass Kid
Eustass Kid is the captain of the Kid Pirates. He possesses a Devil Fruit power connected to magnetism. This manifests in two different abilities, both depicting repulsion and attraction of metals within his vicinity to be used as weapons. The first allows him to repel metallic objects away from himself, such as reflecting a Marine cannonball back towards its shooter. The second ability allows him to draw metallic objects towards him and form them into objects, his most frequent use of this being to form a giant arm made of hundreds of metallic weapons and objects and connecting it to his right hand. When forming this metallic arm, he can use it to punch his opponents, or as a makeshift shield to block even a Pacifista’s laser beams. It is unknown if the firearms connected to his metal arm can fire at his will or not.
According to Kaido, Kid possesses Haoshoku Haki just like Luffy.
#2 – Monkey D. Luffy
Luffy is the son of the Revolutionary leader Monkey D. Dragon, the grandson of the Marine hero Monkey D. Garp and the captain of the Straw Hat Pirates.
After consuming the Gomu Gomu no Mi, Luffy’s body became like rubber, giving him the ability to stretch and attack long distances. Having undergone intense training for over ten years, Luffy is now able to supplement his stretching powers with immense strength, agility, and creativity in combat.
He has also developed several peculiar methods of combat as time passed, adapting new forms by manipulating his elastic body(Gear 2 and Gear 3) and using Haki in conjunction with the fruit’s powers (Gear 4).
Luffy is able to use Haoshoku Haki, a type of Haki possessed only by one in a million people. Luffy used this ability several times in the series, as it was the type of Haki that manifested the earliest.
Since training with Silvers Rayleigh, he have gained incredible proficiency in Kenbunshoku Haki, allowing him to tell what an opponent intends to do. After pushing his Kenbunshoku Haki to its peak during his fight against Katakuri, Luffy gained the ability to see into the future to a limited extent. Katakuri himself even noticed that Luffy’s level of Kenbunshoku Haki was reaching his own.
Luffy has advanced his Busoshoku Haki, allowing him to project it from his palm as well as progress even further by destroying objects he touches from the inside.
#1 – Marshall D. Teach
Marshall D. Teach, also known as Blackbeard, is an immensely powerful pirate even for a (former) member of the Whitebeard Pirates and Shichibukai. Ace once stated that Blackbeard could have been a commander when he was recommended for the position, thereby proving that his strength was equivalent with any of the other commanders, which is extremely notable, as he had not yet eaten a Devil Fruit. The most prominent feats of Teach’s power was defeating three commanders of the Whitebeard Pirates: Portgas D. Ace, Thatch, and later during the Payback War, Marco, the new Captain of the Whitebeard Pirates.
As a member of the Yonko that rule over the New World, Blackbeard is recognized as one of the four strongest pirates in the world. He possesses tremendous physical strength and superhuman endurance.
Blackbeard has become the first and, so far, only user to wield the powers of two Devil Fruits at the same time. With the power of darkness (Yami Yami no Mi), which “reduces anything to nothingness”, and the power of quakes (Gura Gura no Mi), which “brings destruction to everything”, Blackbeard claims himself to be truly invincible and the strongest of them all.
