This article is about the character. For this character's Stand, see Foo Fighters (Stand).
Look at me Jolyne. This is my 'spirit'... This is my 'intellect'... I was alive.

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

F.F. is a mix 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, they soon ally themself with Jolyne Cujoh out of gratitude for being spared.


F.F. can change their appearance at any time. However, their habitual appearance is that of the prisoner Atroe, a woman of average height and slim build with hair or a cap covering her head in a mop or bob forming a serrated edge at its ends.

As their body is composed of plankton, F.F. can contort into impossible curves and even slip through barred fences unharmed. The bodies that they can form into are their sub-body, which they take the form of when initially fighting Jolyne and Ermes, and the main body, which they take the form of outside the water and when they have collected enough plankton. The bodies they have taken over were the three unnamed prisoners, including Atroe.

F.F. is commonly shown carrying a 32 oz. cup near themself when they are not near a water source.

In their Stand form, F.F. takes two main appearances. Naked, a tall, dark, robotic humanoid of masculine proportions, and an alien visage. As F.F.'s identity develops due to their experiences with Jolyne, the true form of their Stand takes on a more human appearance starting to resemble the body they took over while still retaining some of the features of their older form.

F.F. is originally portrayed as an obedient minion whose sole purpose was to fulfill Pucci's orders. After meeting Jolyne, they begin to grow a sense of individuality throughout the story.

F.F.'s personality hinges on the fact that they possess "intellect" but little life experience. During their introductory arc, their only goal is to preserve themself which includes obeying Whitesnake's instructions to guard the discs.[5] As their guardian, they attack people very ruthlessly and aims to kill anyone approaching the disc's hiding place, regardless of their threat level. Being an intellectual being, F.F. places great importance in themself and will implore their enemy to recognize them as sentient by calling them by their name.[6] They also quote the astronomer Fred Hoyle to claim an "intellect" is guiding the universe, even predating it, all to say that even plankton can be intelligent.[7] When F.F. dies, Jolyne meets their ghost for a short time and the former mass of plankton happily contemplates their spirit form that confirms that they were truly alive and sentient.[8]

However, when Jolyne shows mercy toward them and saves them from dehydration, F.F. discovers another way of thinking and grows interested in her, pledging to protect Jolyne and accompany her from now on disguised as the prisoner Atroe.[9]

F.F. was shown not to have much of an eye for detail prior to meeting Jolyne Cujoh and Ermes Costello and laments their existence upon expecting death after being defeated by the two. When Jolyne saves them, however, F.F. immediately begins to notice more details around themself and comes to perceive the world around them as being more colorful. As a result of experiencing this whole new environment, they become extremely curious about everything around them, constantly asking questions to people and experimenting with the world, for instance, trying to do the contrary of what Atroe would have done.[10] While they get along with other people, they have the strongest affinity for Jolyne for giving them freedom and "intellect", of which losing is their greatest fear.

F.F. eventually comes to accumulate enough positive memories of their companions that they come to value them over their own safety, eventually sacrificing themself to close Anasui's wound with their plankton. Indirectly saving Jotaro and Anasui, F.F. departs satisfied to be able to salute Jolyne one last time before ascending to heaven.[11]

Because of their great dependency on water, F.F. is obsessed with it and goes to great lengths to constantly hydrate themself. They carry a cup of water and will fight anyone over it, as well as drink any liquid as long as it contains water, be it blood or spit. Being a mass of plankton with no experience of society, they aren't disturbed by any of it.[12][13]

In summary, F.F. is their own Stand and Stand User. They may reconstitute themself, fill and seal the wounds of others with their flesh, as well as project their flesh as bullets, along with rapid regeneration.



Enrico Pucci had a shack of Stand disks near prison grounds, a collection of different Stands that he had collected over the years while in prison. The area around the shack is generally untouched and desolate. Enrico needed a guardian for these disks, lest they fall into unwanted hands. He threw a random DISC into the ocean, which landed in a group of plankton floating on the surface. Unexpectedly, F.F. was born.

Guarding The Stand Discs

F.F. was told by Whitesnake to stay at the shack where he kept the discs and to kill anyone (other than him) should they come close. Having no other purpose, they did as they were told, protecting the discs. When Jolyne and Ermes approached the shack during an outdoor activity, F.F. attacked but was soundly beaten by both of them. Parched and close to disintegrating, they lamented their meaningless life having only lived serving orders under Whitesnake, but was spared by Jolyne, who gave them water, despite Ermes's protests. Fascinated by their savior, they showed Jolyne her father's missing Stand Disc in gratitude. Subsequently, F.F. inhabited the body of a dead inmate and followed both of them back to prison.

Risk & Reward

After following Jolyne & Ermes back to the prison, F.F. is later seen playing catch with Ermes and Jolyne in the courtyard, with awkward throws. After they get used to it, Miraschon places a wager, to catch & throw 100 balls for $200. They succeed in the bet without repercussions, but Miraschon places an even higher wager, 100 catches for $1,000. This intrigues Ermes, so she decides to throw instead of Jolyne. When they reach about 31, a guard grabs F.F., screaming that outdoor time is over. They throw it anyways after realizing that whatever interferes, they lose the bet. Ermes then bribes the guard, who looks the other way, but he takes away Ermes's glove causing her to drop the baseball. She uses Kiss to bring it back to her, but this is against the rules and Ermes pays for it literally, as Miraschon uses her Stand, Marilyn Manson to collect $380 worth of money, Ermes's gold tooth, and her liver. Jolyne takes her place and raises the wager, 1,000 catches for all that was taken from Ermes. Jolyne and F.F. throw the ball all while chasing down and defeating Miraschon.

Aiding Ermes

Much later F.F. reveals to Jolyne, Ermes's past about her sister Gloria, & her killer Sports Maxx. The two race to find her, only for F.F. to fall victim to Sports Maxx's Stand Limp Bizkit. Later, F.F. heals Ermes & Jolyne, however Ermes's injuries were so severe that she was out of action for a while. 

Protecting Jolyne

F.F. meets Anasui, who is adamant in finding Jolyne in order to marry her, despite her never meeting him. As they reach the Punishment Ward, F.F. saves Jolyne from Kenzou and gets into a heated struggle with him.

Later, tricked by Pucci, F.F. leads their friends into an ambush and suffers a severe blow to their body, knocking the F.F. Stand disc from their head. Dehydrated and nearing death, F.F was able to hear the dying request from Anasui. He gave them permission to possess his body to pluck Jotaro's memory disk from Pucci, not caring what happened to him as long as Jolyne would be happy. F.F. did pluck Jotaro's memory disk from Anasui's body but refused to possess it. Their spirit (taking on the form of Atroe's body, due to growing accustomed to it) heals Anasui's wounds and thanks Jolyne for being their friend, glad that they met. When Jolyne states her intention to retrieve the disk to revive her, F.F. declines, saying that the person revived would not be themself, but another F.F., and they disappear into the wind.

Fred Hoyle, an astronomer, once said "It is wrong to assume, even statistically speaking, that organisms spontaneously appeared on this Earth...
