The Hebi Hebi no Mi, Model: King Cobra is a Zoan-type Devil Fruit eaten by Boa Marigold, one of the Kuja Pirates.

This fruit allows her to transform into a king cobra or hybrid form, granting enhanced flexibility, striking speed, constriction, and venomous attacks. Marigold combines this ability with Haki, making her especially dangerous in close combat.

The fruit is showcased during the Amazon Lily Arc.
