One Piece is Setting Up Imu to Have the Most Dangerous Devil Fruit that Can Make Every Other User Powerless – Theory

Bizarre theory reveals Imu has the strongest Devil Fruit in One Piece.

SUMMARY

Imu, One Piece’s final antagonist, is often regarded as the series’ most powerful character.

His identity has remained a mystery throughout One Piece, and nobody is aware of his goals.
Imu’s power source is unknown, but a certain theory suggests that he has the rarest Devil Fruit, which can negate all other Devil Fruit powers.

Imu, the final antagonist of One Piece is known to be the strongest character in the series. Although not much is known about the character, his devastating powers have been witnessed by One Piece fans and they eagerly await for him to finally make an appearance as a central character in the story.

Imu, also known as Imu-sama sits at the head of the World Government and is believed to be the instigator of everything that is wrong about the One Piece world. His character has been a mystery from the start and no one knows what his goal is in One Piece. He commands the Five Elders and is in some way connected to Joyboy and the One Piece treasure.

While the source of his power is unknown, there is one theory that states that Imu possesses the rarest Devil Fruit and its abilities can make every other Devil Fruit power useless.

Imu is the Strongest Villain in One Piece

Imu is a mystery ruler who sits on the Empty Throne. He was originally revealed in the Reverie arc, and both the World government and the general public are completely unaware of his presence. Eiichiro Oda is keeping almost everything about him a secret and probably will introduce him in the final war of One Piece. 

As he is the ruler of the world, Imu’s commands are permanent and cannot be challenged, and the Five Elders personally ensure that they are followed no matter what. According to Ivankov, Imu is believed to be from the Nerona family, who were among the First Twenty Founders of the One Piece world 800 years ago.

The recent One Piece chapters have shed a little light on Imu and his powers, and as the story has entered the final saga, many One Piece fans believe that he is soon going to make an appearance that is going to shock everyone.

One Piece Theory States Imu has the Most Dangerous Devil Fruit

It is a well-known fact that although Devil Fruit is one of the greatest powers in the One Piece universe, its users lose the ability to swim because the sea rejects them and their powers. However, according to one theory, Devil Fruit users lose their ability to swim not as a result of their powers, but as a result of another Devil Fruit that can control water.

The theory posted by @Wafer-the-dog on YouTube, states that there is a devil fruit that can manipulate water in its awakened form. As the awakened form of Devil Fruit allows the user to control the power of the elements granted by the fruit, this water devil fruit grants the user authority to control the effects of Seawater which is almost 90% of the One Piece world.

The person who possesses this water devil fruit is none other than Imu and he is the one who made Devil Fruit users powerless in water by controlling its effects. When Imu finally makes a move in One Piece, he will use these powers against his opponent(Luffy) and take control of the final war.
