One Piece Wiki

The Bomu Bomu no Mi is a Paramecia-type Devil Fruit that allows the user to make any part of their body explode, whether it be their limbs, hair, mucus, or even breath, making the user a Bomb Human (爆弾人間 Bakudan Ningen?).[2] It was eaten by Gem, better known by his Baroque Works alias Mr. 5.


  • Bomu is the Japanese spoken word for "bomb".
  • It is called the Boom-Boom Fruit in the Viz manga, the sound bombs make.
  • It is called the Bomb-Bomb Fruit in the 4Kids, Funimation, and Odex dub.


The Bomu Bomu no Mi resembles a dark purple apple covered in S-shaped swirls with a rope-like yellow stem. The coloration and shape also make it resemble a stereotypical bomb (black and spherical with a stringy fuse). The stem is tattered at the end, making it look like a lit fuse.

Strengths and Weaknesses

Gem exploding his arm on Miss Monday.

The fruit's main strength is that the user can detonate their entire body or limbs in a manner akin to a living human bomb, generating powerful explosive forces that harm anything but the user itself. The explosive quality extends to bodily emissions such as mucus and breath, giving the user the capacity to utilize ranged attacks should they find ways to weaponize those substances.

The fruit also grants immunity against all other explosions, including even cannonballs,[3] as well as the ability to evaluate their quality. For example, Gem commented that Usopp's Gunpowder Star tasted bad because he was using low quality gunpowder.

However, it seems that the ability only activates when the user initiates contact with something, or at will, as both Zoro and Luffy have been seen hitting Gem without him exploding. Also, despite the user's explosion immunity, they are not particularly resistant to fire.[4] Other than that, this fruit has no apparent weaknesses aside from the standard Devil Fruit weaknesses.


The simplest form of Gem's power usage is to pick his own mucus and then flick it at his opponents for long range strikes. For close range, he can detonate his arms, legs or all of his body to inflict damage. Strangely, despite the fact that the explosions do not harm Gem nor his clothes, he prefers to first pull up his sleeves whenever he intends to blow someone up directly with his arms.[5]

Gem "digesting" an explosion.

Gem often fights in conjunction with Mikita because his powers tend to complement hers, since the impacts generated by his explosions provide enough impulse for the latter to fly around under the effects of her own abilities. Gem also generally does not react against explosive projectiles, knowing they will not harm him at all. He may even ingest them too, in order to keep the explosion contained into himself and protect his allies. That being said, Gem can be tricked into eating something else that looks like an explosive but is not by a clever enough opponent.[6]

Gem has access to a Flintlock .44 Caliber 6 Shot Revolver that gives him a method to weaponize his own explosive breath into functional bullets that can be rapid fired, doing so by first blowing air into the gun's chambers to load it with "ammo" and then firing normally. He claims to dislike using this against enemies he perceives as weak though, but will do so anyway if feeling impatient enough.


Gem flicks his dried nasal mucus at Zoro, which explodes after being cut.

  • Nose Fancy Cannon (鼻空想砲ノーズファンシーキャノン Nōzu Fanshī Kyanon?): An effective technique despite Zoro considering it disgusting, Gem digs a dried mucus out of his nose and flicks it at the opponent. The snot explodes on contact with the opponent and creates a surprisingly large blast.[2] This is called Nez-Palm Cannon in the Viz Manga, Bomb Boogie in the 4Kids dub, and keeps its original name in the Funimation dub. In the move's English manga name, nez is French for "nose" and the spelling is meant to be a pun on "Napalm", because of how Gem picks his nose. This attack is also a pun when translated into Japanese, as "nose fancy" (hanakuusou) in Japanese is pronounced very similarly to "nose crap" (hanakuso), i.e mucus.
  • Nose Fancy Double Cannon (鼻空想ニ連砲ノーズファンシーダブルキャノン Nōzu Fanshī Daburu Kyanon?): It is the same as Nose Fancy Cannon except he flicks mucus with both hands at the same time.[7] In the Viz Manga, this is called Nez-Palm Double Cannon.
  • Kick Bomb (足爆キッキーボム Kikkī Bomu?): Gem kicks his opponent, detonating his leg on impact.[8] He first used this on Monkey D. Luffy halfway through the Little Garden Arc, taking advantage of the Straw Hat captain's immobility at the time. In the Viz Manga and Funimation dub, this is called Kicky Bombs.

Breeze Breath Bomb.

  • Breeze Breath Bomb (そよ風息爆弾ブリーズ・ブレス・ボム Burīzu Buresu Bomu?): Gem blows into the chambers of a revolver pistol, then fires his breath as invisible exploding bullets. He first used this against Usopp and Karoo.[9]
  • Zenshin Kibaku (全身起爆 Zenshin Kibaku?, literally meaning "Full Body Exploding"): Gem grabs his opponent in a bear-hug then detonates his entire body at once. According to Gem, this technique is so destructive, it does not even leave any of his opponent's bones behind. However, Gem did not have the chance to actually use this move as Zoro was able to knock him out before he could kill Usopp.[10] This attack is called Full Body Explosion in the Funimation dub.


  • This ability is very similar to the Pamu Pamu no Mi, and the non-canon Basu Basu no Mi, as they all involve explosions. The main difference is that this fruit is limited to the user's body, while the others can affect other objects.
