For other models of this fruit, see Hebi Hebi no Mi (Disambiguation).

The Hebi Hebi no Mi, Model: King Cobra is a Zoan-type Devil Fruit that allows its user to turn into a king cobra hybrid and a full king cobra at will. It can also give the user the ability to create and spit venom. It was eaten by Boa Marigold, who was force-fed it by a World Noble.[2]


  • Hebi (蛇) is Japanese for "snake".
  • It is called the Snake-Snake Fruit King Cobra Model in the Viz Manga.
  • It is called the Snake-Snake Fruit: Model King Cobra in the FUNimation subs.

Strengths and Weaknesses

The fruit's major strength, as demonstrated by Marigold, is that along with physical strength gained from their transformed forms, they gain a long versatile body that they can use like a real king cobra, as well as the ability to spit purple venom for long ranged combat.[3] As a cobra is a predatory reptile, Marigold is better adapted for combat than normal Zoan types.[4] The hybrid form also seems to endow the user incredible resilience to heat and fire, and could even use fire itself wreathed on the user's person as a weapon, though it is likely that this is just Marigold's Busoshoku Haki armor.[5] It is not known for how long the user can withstand the fire, however.

The tail of the form can be tied to an object to limit their movement and leave them vulnerable.[6] Other than that, this fruit so far does not seem to have any specific weaknesses outside the standard Devil Fruit weaknesses.


The powers of the fruit have been used mostly by Marigold for combat purposes. With her long hybrid body gained from the fruit's powers, she is capable of striking her opponents at long range, constrict them, and spit lethal poison.[3] Marigold's Devil Fruit was fed to her originally for entertainment purposes only and so while unseen being used this way, it means the Hebi Hebi no Mi, Model: King Cobra has a degree of performance value.[2]


Saragi no Mai

  • Saragi no Mai (蛇穴の舞い Saragi no Mai?, literally meaning "Snake Pit Dance"): Joining with her older sister in their half snake forms, Marigold and Sandersonia both battle an opponent together. This was first seen being used against Luffy.[1] Saragi is the name of a city in Nara. The kanji of the battle formation's name literally means "Snake Pit". This is called Snake Burrow Dance in the VIZ Manga.
  • Modoku (猛毒 Mōdoku?, literally meaning "Deadly Poison"): Marigold spits a corrosive liquid venom from her mouth. In the anime, if the spit does not hit the target, it starts emitting poisonous smoke that can affect nearby opponents. It was first seen used against Luffy.[3] In the FUNimation dubs this is called Powerful Poison.
  • Heavy Stick (蛇突ヘビー・スティック Hebī Sutikku?, literally "Snake Thrust"): Marigold uses her Busoshoku Haki imbued tail to stab her opponent. This was first seen being used against Luffy.[3] The name of this attack is a pun as "heavy" and hebi sound the same. It could be translated to as "Snake Stick" as the kanji used for "heavy" is that of "snake". This is called Heavy Snaky Stick in the VIZ Manga and Snake Stick in the FUNimation dubs.

Hebigami-Tsuki: Salamander

  • Hebigami-Tsuki: Salamander (蛇髪憑き・炎の蛇神サラマンダ Hebigami-Tsuki: Saramandā?, literally meaning "Snake-Hair Possession: Flame Snake God"): Marigold lights a match and sets herself on fire, then forms her hair into two snakes on either side of her. When this attack is used with Sandersonia's "Yamata no Orochi" technique, it is said to be the absolute ultimate attack, for it aims towards the target at all possible directions and leaves no blind spots. It is unknown if the resistance to fire and the ability to manipulate hair into snakes is the result of the Devil Fruit or a Life Return-like ability. This was first seen being used against Luffy.[5] The name of this technique comes from the mythological fiery lizard Salamander. This is called Snake Hair Possession: Salamander in the VIZ Manga and Medusa Hair: Salamander in the FUNimation subs.


During their time as slaves, the Gorgon Sisters were force-fed Devil Fruits, as a form of sick entertainment. Marigold, in particular, was fed the Hebi Hebi no Mi, Model: King Cobra. In order to hide their shame, the sisters told the rest of the Kuja Tribe that these powers were actually a curse from their alleged heroic actions of slaying a monster called Gorgon.


  • Not knowing that it is actually the power of a Devil Fruit, the Kuja of Amazon Lily attribute Marigold's ability to turn into a king cobra to a curse that she and her sisters supposedly got from defeating a monster called a Gorgon.
  • While some cobras can spit venom, the king cobra is not among them.
  • Just as Marigold (along with her sister Sandersonia) is the largest of the known Kuja, the king cobra is the world's longest venomous snake, averaging 3.6–4 m (12–13 feet) in length. A particularly large specimen was kept captive at the London Zoo, and grew to 5.7 m (18.8 ft).
