The Beta Beta no Mi[3] is a Paramecia-type[2] Devil Fruit that allows the user to create and control mucus, making the user a Mucus Human (粘液人間 Nen'eki Ningen?).[4] It was eaten by Trebol.

This ability is not to be confused with a Logia-class power, as the user cannot transform their body or any part of their body into mucus.


  • "Betabeta" is a Japanese onomatopoeia for "sticky" or "clinging", which reflects on the properties of the substance this power produces.
  • In the FUNimation sub, it is called the Sticky-Sticky Fruit.

Strengths and Weaknesses

The fruit's major strength is the ability to create limitless amounts of mucus, which affords the ability to restrain movements and allow the user to attach themselves to surfaces. The mucus is strong enough to hold a ship.[5]

Luffy's Haki Fails to Hurt Trebol

Luffy's punch is ineffective due to missing Trebol's actual body.

The limitless amounts of mucus that the user can generate, similarly to the Doru Doru no Mi and the Doku Doku no Mi, can make the fruit appear to be a Logia. Trebol used this against Monkey D. Luffy, who hit his mucus coat under the impression that it was part of his body, and was shocked when nothing happened. It also seems that the user can give different colors to their mucus, as seen when Trebol made part of his mucus coat look like his body.[6]

The mucus is flammable and will cause it to explode violently upon contact with a spark; though potentially a liability, the user can use this to his or her advantage.[7] Trebol appears to have a constantly runny nose, though it has yet to be determined whether this is actually a side-effect of the fruit's powers. At the same time this does make it easier for Trebol to shoot snot at his enemies.[8] If the user takes significant wounds, they will lose control of any mucus they generate leaving him vulnerable to any more attacks.[9] Aside from that and the standard Devil Fruits' weaknesses, this ability has no other known weakness.


Trebol uses it to stick to various surfaces, such as roofs or walls.[1] By producing mucus he is able to extend his reach and seize his targets from afar, and keep them in place (or make moving more difficult for them).[10] He can also fire off mucus with extreme force and precision, piercing a wall with explosive force while striking a fly in between its eyes,[11] or use it to seize heavy objects and use it as a flail.[5] As the mucus is flammable, he can ignite it with a match upon capturing his opponents and causing incendiary damage.[7]

Trebol made it appear as though the fruit's power is that of a Logia by covering himself in a thick coat of mucus around his emaciated body, which the opponents would assume to be part of his body and believe it to be intangible when attacking that empty space inside the mucus shell, giving him an advantage over enemies who fall for this ploy.[2]

Named Techniques

Beta Betton Meteora

Beta Beta Chain: Beta Betton Meteora.

  • Beta Beta Chain (ベタベタチェーン Beta Beta Chēn?, literally meaning "Sticky Sticky Chain"): Trebol releases mucus and shapes it into a chain with its other end sticking on an object of various sizes. This was first seen used to grab a ship.[5]
    • Beta Betton Meteora (ベタベットン流星(メテオーラ) Beta Betton Meteōra?, literally meaning "Sticky Stick Meteor"): After seizing a heavy object with Beta Beta Chain, Trebol throws it on his target, similar to a flail. This was first used to smash the Officer Tower. "Meteora" is Italian for "meteor".[5]
  • Hanamizu Shinken Shirahadori (ハナ水真剣白刃取り Hanamizu Shinken Shirahadori?, literally meaning "Snot Real Sword Blade Grab"): Trebol manipulates the snot running out of his nose, in order to defend against sword strikes. This was first seen in use against Trafalgar Law, but was cut up before it made contact.[8] Shinken Shirahadori is a set of techniques for defense against sword attacks, from the Wadō-ryū style of karate.
  • Beto Launcher (ベトランチャー Beto Ranchā?) : This attack was first used against Law on the Dressrosa palace rooftop, but was not seen.[12] However, in an extended anime scene the attack was shown: It consists of Trebol throwing several flammable sticky spheres that explode on contact.[13]
  • Beta Betton Launcher (ベタベットン・ランチャー Beta Betton Ranchā?): Trebol launches dozens of spheres of mucus at his opponent, who is trapped in place wherever the spheres make contact with their body. This attack was first used against Law.[14]
