Devil Fruits are mystical fruits found throughout the world that, when consumed, provide the eater a special ability, depending on the type and variation of the Fruit itself.
Devil Fruits are the origins of the powers of some of the strongest people in the current generation of One Piece World, including Rookie Pirate Crews, Marine Admirals, Shichibukai, and at least two Yonko(Marshall D. Teach and Charlotte Linlin). All Devil Fruit are categorized into three types/classes: Paramecia, Zoan and Logia.
Certain Devil Fruits are noted to be “unique” or “special”, even for their respective classes.
Let’s have a look at them:
#Goro Goro no Mi, which was mentioned by Nico Robin to be one of the devil fruits with the reputation of being “invincible”. It allows the user to create, control, and transform into electricity at will, making the user a Lightning Human.
#Yami Yami no Mi, which has been claimed to be “unique”, even for a Logia. It allows the user to create and control darkness at will, making the user a Darkness Human. This fruit is considered “unique” even for a Logia-type, and the ability it grants is said to be the “most evil”.
#Gura Gura no Mi, which has been called the strongest Paramecia, equal to a Logia. It allows the user to create vibrations, or “quakes”, making the user a Tremor Human. This fruit is fearsomely reputed to be able to destroy the world, and is considered to be the strongest Devil Fruit within the Paramecia class, having powers no weaker than those of a Logia Devil Fruit.
