FOO FIGHTERS (F.F)
Arguably one of the funniest characters for me to be obsessed with throughout my Jojo adventure. The easiest way to explain why I love F.F so much is that she (or rather, it) is just a sentient stand living life as a female prisoner. She's a goofball! She's a bunch of plankton posing as a human being and what is not to love there? Her character is reminiscent of another Jojo character, Mikitaka, an alien who's entire bit is poorly fitting in to their surroundings.
Originally, F.F is seen as an enemy stand who only does what it's told, and the audience expects F.F to be defeated and subsequently, destroyed. However, as Jolyne spares her and the story progresses, F.F begins to develop both a close bond with Jolyne and Ermes, and an actual personality. Despite being a stand, the audience can't help but get attached to her character. Her character reminds me a lot of Power from Chainsaw Man, both blunt and sometimes crude, but both harbor deep loyalty for their friends.
