Gear 5 is an absolutely incredible ability that Oda introduced for the first time in the Wano Country arc of One Piece. This ability is inherently tied to the power of the Hito Hito no Mi, Model: Nika. Eaten by Monkey D. Luffy, this Devil Fruit grants him the power of a rubbery body. However, it is the awakening of this Devil Fruit that truly makes it shine. Once the Devil Fruit is awakened, the true power of the fruit is brought into action. After centuries, Luffy was the first one to manage to awaken it and he gained immense powers thanks to it.

Luffy calls his awakening Gear 5 and it essentially gives him greater strength, as well as an even more rubbery body. Above all, it gives Luffy the ability to make use of the power of imagination and do whatever he wishes as long as he can imagine it. While Luffy is the primary user of Gear 5 in One Piece, there are three other users who have already been mentioned in the story.

Monkey D. Luffy

  • Gear 5 Awakened In: Wano Arc

Of course, Monkey D. Luffy is the primary user of Gear 5 in One Piece. Luffy was the first person seen using this power, and he did so in the Wano Country Arc. After his immense fight against Kaido, Luffy faced certain death and even his voice completely vanished, implying his end. However, it was at this point that Luffy's mind and body caught up with his abilities, and thus, the Nika fruit finally awakened.

Luffy was able to defeat Kaido with the power of Gear 5, and since then, he has continued to make use of this ability against various strong enemies, such as Kizaru and the Five Elders. The potential of Gear 5 is vast and Luffy can still improve its usage even further.

Jewelry Bonney

  • Gear 5 Awakened In: Egghead Arc

Jewelry Bonney is a very important character in the Final Saga of One Piece. In the Egghead arc, she took the front seat by becoming the deuteragonist of the arc, and it was here that she utilized the power of Gear 5 for the very first time. Bonney was able to make use of Gear 5, thanks to her very own Devil Fruit, the Toshi Toshi no Mi.

With this Devil Fruit, Bonney can turn into reality anything that she thinks is possible. However, the narrower the possibilities get, the lower the chance of Bonney being able to realize that particular future. On the flip side, as long as the possibility of doing something exists, Bonney can easily make it into reality. By following this logic, Bonney was able to acknowledge the existence of Sun God Nika by witnessing Luffy use his Gear 5. Since she knew it was possible, Bonney was also able to use this Devil Fruit ability to turn into Nika herself. In her Nika form, Bonney is tremendously powerful and she was even able to deal deadly blows to Saint Saturn, as seen in the Egghead arc. The stamina toll on her young body is still way too much, but with time, Bonney can truly utilize the power of this Devil Fruit in incredible ways.

Joy Boy

  • Devil Fruit: Hito Hito no Mi, Model: Nika
  • Timeline: 900-800 Years Ago
  • Gear 5 Awakened In: Unknown Time

Before Luffy, there was another user of Gear 5 in One Piece, and that is Joy Boy. Joy Boy existed long ago during the Void Century, as confirmed in the Egghead arc of the story. He was the previous user of the Hito Hito no Mi, Model: Nika, and he utilized its powers immensely well. How Joy Boy ate the Devil Fruit remains unknown, but it is already clear in the story that he did, in fact, utilize this fruit's abilities, and that he was the previous Nika.

With his abilities, he took on the Twenty Kings of the world, and this battle raged for many years. Eventually, Joy Boy lost the battle and died, however, his will has now been inherited by none other than Luffy. Fans will most definitely get a proper look at Joy Boy with Gear 5 once his own flashback begins, which should be at some point in the final saga.

  • Devil Fruit: Unknown
  • Timeline: Around 3000 Years Ago
  • Gear 5 Awakened In: Unknown

Long before Joy Boy, the original Sun God Nika existed in the One Piece world as well. This was confirmed in the Elbaf arc of One Piece. Years ago, fans believed Joy Boy to be the first Sun God Nika, but it is now clear that the first Nika emerged during the First World, which was approximately around 3,000 years ago.

It was there that the Sun God Nika fought first, which means that particular deity was the first user of Gear 5 in One Piece. Very little is known about this individual, but according to the Harley, Nika went up against the Serpent of Hellfire and the Earth God together, and their battle laid waste to the entire world. It was many years after the destruction of the entire world that life took form again, and that is where the Second World, where Joy Boy emerged, took place.
