F.F (Foo Fighters)

Extremely curious: F.F. initially knows very little about ordinary human life. She becomes fascinated by basic human experiences and constantly tries to understand things that humans take for granted.

Energetic and excitable: She's very enthusiastic and can go from completely calm to incredibly excited in seconds. Her reactions are often exaggerated and funny.

Blunt: F.F. doesn't have the same social understanding as the other characters. She tends to say exactly what she's thinking without worrying much about whether it's socially appropriate.

Loyal: Once she considers someone a friend, she becomes extremely devoted to them. Her relationship with Jolyne in particular develops into genuine friendship and trust.

Protective: F.F. becomes willing to put herself in danger to protect the people she cares about. Despite her strange origin, she develops a very strong sense of attachment to her friends.

Childlike in some ways: F.F. has an almost childlike fascination with the world. She can be surprisingly innocent about concepts that humans normally learn while growing up.

Emotionally sincere: One of her most appealing traits is that her emotions aren't fake or calculated. When she's happy, she's really happy; when she's angry, she's genuinely angry; and when she cares about someone, she genuinely cares.

Increasingly human: This is probably the most important aspect of her character. F.F. begins with little understanding of what it means to be an individual human being, but through her experiences with Jolyne and the others, she gradually develops her own identity, emotions, values, and understanding of friendship.

Appearance: Hair: She has short, dark green/teal hair, cut around chin length. It is fairly straight and slightly messy, with pieces framing her face.

Eyes: Her eyes are large and expressive, with a distinctive greenish/turquoise color.

Face: She has a youthful-looking face with relatively soft features. Her expressions can change dramatically depending on her mood.

Build: She has a slim, athletic-looking build.

Skin: Her skin is light,
