The Elbaf Arc is delving into the past and revealing the full extent of Imu’s terrifying power. Even legendary alliances like Rocks, Roger, and Whitebeard couldn’t hurt Imu.
One Piece fans have been waiting to witness Imu’s true power since author Eiichiro Oda revealed the existence of this ultimate villain. As the story delves into the Elbaf arc, that’s exactly what’s happening.
Before the flashback of Loki in Elbaf officially took place, Imu showed overwhelming strength when he single-handedly crushed Elbaf. This power is further demonstrated in Loki’s flashback, where Imu is revealed to have fought legends such as Rocks D. Xebec, Gol D. Roger, Whitebeard, Big Mom, Garp, and Kaido at the same time in God Valley.

Despite having to fight such “monsters”, Imu remained unharmed, and was clearly invincible as of now. However, there was one pirate who once terrified Imu, and that was none other than Joy Boy.
Joy Boy is the only one who can defeat Imu
One Piece fans have been looking forward to a huge battle between Imu and Rocks D. Xebec ever since their first meeting was revealed. However, few people expected the battle to be so one-sided. Even though Rocks possesses extremely powerful Conqueror’s Haki, Imu remains completely unharmed.
Just one attack from Imu and Rocks D. Xebec was defeated. Even Imu not only defeated him, but also made him her slave. According to what was seen in One Piece chapter 1163, Imu used the Domi Reversi technique to control Rocks D. Xebec. Now, the task of stopping Rocks (being controlled) will fall to Roger and Garp.
Obviously, Rocks D. Xebec cannot be a match for Imu. However, Joy Boy is definitely someone who has that ability. Joy Boy – who lived in the Void Century was a previous user of the devil fruit Hito Hito no Mi, Model: Nika. He belonged to the once prosperous Great Kingdom, was the first to set sail and was called a pirate.
Most importantly, Joy Boy has incredible power, especially since he is the Nika of the Second Period in One Piece. Joy Boy fought Imu and the other kings during the Void Century and lost, but he instilled deep fear in them. When Joy Boy’s Haki was released during the Egghead arc, Imu was seen trembling in fear.
Luffy is the new Joy Boy and he will defeat Imu
Remember that Joy Boy is a title, not a name. The previous Joy Boy was unable to defeat Imu, but the current Joy Boy, aka Monkey D. Luffy, will eventually defeat him. Joy Boy – as an entity is the only one who can defeat Imu, and all of that will become possible thanks to the power of the Hito Hito no Mi devil fruit, Model: Nika.
However, Luffy will not be able to defeat Imu in the near future. The match between them may take place in the Elbaf arc, but there is a high possibility that it cannot be completely resolved. Currently, the difference in strength between the two is still too great, Imu falling now is too early. Luffy needs to reach new heights before he can defeat the World King.
