3 – TRAFALGAR LAW
Law 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.
Furthermore Law can use his power to generate high voltage energy; he can generate electrical energy to shock his opponents, and he can generate a blade of energy that he can use to damage his enemies internal organs without leaving an external wound.
Law has achieved Devil Fruit awakening, allowing him to conjure a variety of special room spheres that are applied directly to specific objects instead of a designated area, meaning those rooms move alongside whatever they are currently covering. With K-Room, Law can adhere a miniature room to his weapons, which then gain the ability to extend as far as he desires, harmlessly bypass anything solid and directly operate on the insides of whatever they may phase through. With R-Room, Law is able to create and throw a room on a particular object and dictate a specific effect to take place in it, like erasing any sound made by the object in question. This directly addresses one of the fruit’s biggest weaknesses, which is the stationary nature of its regular field of range.
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 also shown great proficiency in Busoshoku Haki (he also possesses the ability to use Kenbunshoku Haki).
2 – BLACKBEARD
Blackbeard is the Admiral of the Blackbeard Pirates and the newest member of the Yonko. He has an immense amount of superhuman endurance and tremendous physical strength even for his comparable size.
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 pirate in the world.
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.
Blackbeard is confirmed to possess the ability to use Busoshoku Haki and Kenbunshoku Haki.
1 – DRACULE MIHAWK
Mihawk is the current holder of the title, “Greatest Swordsman in the World”.
Part of Mihawk’s reputation as the most powerful master swordsman in the world is also due to his tremendous superhuman physical power and fortitude which supplements his mastery of swordsmanship. He possesses an immense amount of skill in battle and has exceptional eyesight.
The fact that Mihawk used to be a rival of one of the Yonko implies that Mihawk might be one of the strongest characters in the series. Infact he has been known to have frequently fought with Shanks when they were younger. Their battles were said to shake the whole of the Grand Line and Mihawk often sought Shanks out for duels. However, Mihawk lost interest in him after Shanks lost his left arm. Mihawk has remained unharmed thus far throughout the entire series.
