03Appearance
04Personality
Foo Fighters is originally portrayed as an obedient minion whose sole purpose is fulfilling Pucci's orders. After meeting Jolyne, she begins to grow a sense of individuality throughout the story.↗
Foo Fighters's personality is centered around the fact that she possesses "intellect" but little life experience. During her introductory arc, her only goal is obeying Whitesnake 's order to guard the DISCs. Being an intellectual being, Foo Fighters places great importance in herself and implores her enemies to recognize her as sentient by calling her by her name.↗↗↗↗
When Jolyne shows mercy toward her and saves her from dehydration, F.F. discovers a new outlook on life and grows interested in her, pledging to protect Jolyne and accompany her in disguise as the prisoner Atroe. As a result of experiencing the new environment of the prison, she becomes extremely curious about everything around her, constantly asking questions to people and experimenting with the world, such as when she tries to do the opposite of what Atroe would have done. While she gets along with others, F.F. has the strongest affinity for Jolyne for giving them freedom and "intellect," which she fears losing above all else.↗↗↗
05Abilities
Stand
In short, F.F. is her own Stand, her very existence relying upon the Stand DISC inserted into her.↗
06Story
SPOILERS
Background
During his time at Green Dolphin Street Prison, Enrico Pucci had collected a number of Stand DISCs under the guise of his own Stand, Whitesnake. Seeking a hiding place for his collection, Pucci chose the prison's farm, a remote, untouched, and desolate area of the prison. The farm's distance from the main prison building necessitated a guardian for the DISCs, lest they fall into the hands of Pucci's enemies.↗
Guarding the Stand DISCs
Foo Fighters was told by Whitesnake to stay at the warehouse where he kept the DISCs, and to kill anyone other than him should they come close. Having no other purpose, she did as she was told, protecting the DISCs. At one point, Foo Fighters kills two inmates who venture inside of the warehouse and completely absorbs their bodies, making it appear that the inmates have disappeared.↗
Battle Against Jolyne Cujoh and Ermes Costello
Seeing the search party, Foo Fighters splits herself to take them all out. First, she manages to discreetly take over the bodies of three of the prisoners, while creating a supplementary body from the two missing inmates. When the guard wanders into the water, Foo Fighters injures him, leaving him unconscious. A small part of Foo Fighters baits Ermes near a bucket and attacks, throwing the bucket onto her head and dragging her underwater.↗
Alliance with Jolyne
Ermes prepares to deal the finishing blow. However, Jolyne spares Foo Fighters and gives her some water, figuring that she didn't know any better and only wanted to survive. Touched by her compassion, Foo Fighters agrees to become Jolyne's ally and allows her to retrieve Jotaro's Stand DISC. Foo Fighters then takes over the corpse of a woman named Atroe, hoping to accompany Jolyne back to the prison and protect her.↗
Battle Against Miraschon
After following Jolyne and Ermes back to the prison, F.F. is later seen playing catch with Ermes and Jolyne in the courtyard. Another inmate approaches and sips F.F.'s cup of water despite her protests, thinking that she is still the meek prisoner Atroe. In response, F.F. shoots her plankton into the inmate's mouth, causing him to throw up all of the water along with some bonus liquid.↗
Battle Against Sports Maxx
F.F. notices that her host is not welcome in the prison and decides to change her habits. Using Atroe's impulses, F.F. begins to do the opposite of what her host instinctively wants, hoping to gain appreciation among the other inmates. Her efforts meet with limited success. When Jolyne notes that she hasn't seen Ermes in a while, Foo Fighters reveals that a gangster named Sports Maxx killed Ermes's sister, Gloria, Atroe having heard of it from a newspaper.↗
The Ultra Security House Unit
A few days after Ermes gets her revenge, F.F. meets with Emporio. Worried about Jolyne, who has let herself be taken to the Ultra Security House Unit alone, F.F. plans to sneak into the building to help her. With Weather Report still in the medical wing, F.F. considers allying with Burning Down the House 's other resident, Narciso Anasui. Emporio warns her that Anasui is a convicted murderer, but F.F. plans to force him to cooperate nonetheless.↗
Battle Against Kenzou
Kenzou and Foo Fighters properly engage each other. The old man summons Dragon's Dream and uses it to locate a "lucky spot" where he is immune to attack. Moving into the lucky spot, he effortlessly avoids F.F.'s shots and drives his fist inside of her throat, attacking her vertebrae to trigger a secretion of mucus from the adrenal gland and a subsequent death by internal drowning. After delivering the strike, Kenzou turns to face Jolyne, but F.F.↗
Birth of the Green Baby
As the three leave the execution room via the stairs, Anasui asks F.F. to trip Jolyne so he can catch her. F.F. reluctantly does so, but Jolyne notices a prisoner holding the bone she seeks and uses her string to chase after him, missing Anasui entirely. The three corner the prisoner, but discover to their horror that he is being turned into a plant alongside the rest of the inmates, Jolyne included.↗
Battle Against Whitesnake
F.F. finds D an G just as a group of paramedics reach him, and notices a priest staring at the assassin. Undeterred, she disguises herself as one of the paramedics and prepares to shoot D an G as he is being loaded into an ambulance. However, her assassination attempt is stopped by another paramedic, who grabs her arm under orders from a thrown DISC. After knocking out the other paramedic, F.F. is confronted by Pucci, and finally realizes that he is Whitesnake's user.↗
