Foo Fighters (Stone Ocean)

Foo Fighters (フー・ファイターズ Fū Faitāzu), commonly referred to as F.F. (Fエフ・Fエフ Efu Efu), is a primary ally featured in the sixth part of the JoJo's Bizarre Adventure series, Stone Ocean.

F.F. is a fusion of Stand and Stand User; a colony of plankton that is organized, maintained by, and essentially equivalent to the Stand, Foo Fighters. At first serving Enrico Pucci, she soon allies herself with Jolyne Cujoh out of gratitude.
