Foo Fighters, commonly referred to as F.F. is a primary ally featured in the sixth part of the JoJo's Bizarre Adventure series, Stone Ocean. A self-maintained colony of intelligent plankton that is essentially equivalent to the Stand, Foo Fighters, F.F. originally serves Enrico Pucci as a guard for the priest's DISC collection, but she soon allies herself with Jolyne Cujoh out of gratitude.
