The Kumo Kumo no Mi is a Zoan-type Devil Fruit eaten by Vice Admiral Onigumo of the Marines. This fruit allows the user to transform into a spider or spider hybrid, granting abilities associated with arachnids.

Onigumo uses this Devil Fruit to enhance mobility, physical combat ability, and restraint techniques, including the use of extra limbs for grappling and capturing enemies. Unlike Ancient Zoan variants, this is a standard spider Zoan with no prehistoric classification.

The fruit is prominently seen during the Marineford War, where Onigumo participates in the execution proceedings and large-scale combat.
