**Fiona Frost** (フィオナ・フロスト, *Fiona Furosuto*?) is a major recurring character of the *SPY x FAMILY* series. She is a spy for WISE who acts under the codename **"Nightfall"** (〈夜帷 (とばり) 〉, *<Tobari>*?). She works undercover as an assistant to Loid Forger at Berlint General Hospital to provide him with mission details.

## Appearance

Fiona is a fairly tall woman with pale complexion. She has bobbed hair of a light lavender color and a long fringe covering much of the right side of her face, worn swept behind her left ear. She has cold purple eyes framed by light-colored eyelashes, and most often is seen wearing an emotionless expression. She is described as beautiful by Yor. Fiona's age is currently uncertain, but she appears to be younger than Loid.

Fiona is introduced wearing a duffel coat with a black turtleneck and pants underneath, and her outfit when visiting the Forgers' house consists of a black blazer and a low-dip light shirt. Her stud earrings take the shape of WISE's symbol.

## Personality

After being trained by Twilight to hide her true emotions, Fiona tends to remain emotionless on the surface—even when making a mental confession of love to Loid. Fiona is deeply in love with Loid, to the point of being capable of compromising Operation Strix by visiting the Forger's residence and even telling Sylvia Sherwood and Loid himself to replace Yor and let her take over the role of the Forger wife. Fiona thinks of herself as the superior partner to Loid and wishes to separate him from Yor so they can be together. To others, like her co-workers, Fiona is seen as an unscrupulous and ambitious woman, capable of backstabbing her peers to build a reputation even bigger than Twilight's own. While this is true to an extent, her desire to build her reputation stems not from a lack of scruples or ambition per-se, but from a desire to impress Loid.

Despite her usually emotionless facade, Fiona has let her true feelings surface in rare instances. When she challenges Yor to a tennis match with the intention of breaking her, Fiona is visibly in shock upon witnessing Yor's absurd strength and is crushed after losing to her. As she speeds away in her car, she breaks into tears as she declares to never give up her ambition. Later, when she sees Loid defeated and his life endangered at the hands of Winston Wheeler, Fiona goes into a rage and openly speaks her feelings as she defeats the rogue spy. She is also capable of severe embarrassment, which happened to her due to recognize that Sylvia knows about her feelings for Twilight.

Fiona can act hastily in getting missions done, especially if Loid is involved. For example, when infiltrating the Campbelldon tennis tournament with Loid, Fiona pushed herself to complete their mission and impress him as much as she could. Fiona is also very distrustful of others and is willing to use them as pawns to fulfill her goals, like when she gained the help of a counterfeiter by calling SSS agents on him and subsequently protecting him from them. Despite her methods, Fiona is a proficient spy and capable of partnering with others, like Franky, who she has grown to trust to some extent.

## Abilities and Skills

**Enhanced Strength:** While not as powerful compared to the stronger characters in the series, Fiona has impressive physical strength, shown when she took down the Bolic Brothers with her tennis smashes, who were strong enough to rip apart a steel fence with their bare hands, and, to some degree, even managed to rally a shot by Yor in a tennis match. After losing to Yor in said match, Fiona took to the mountains to train for her revenge match, which has improved her strength and endurance. She was able to pull a pile of tied-up logs with a bear sitting upon it and tame an alligator.

When Fiona reaches a state of complete rage, her physical prowess becomes extraordinary, allowing her to deliver inhumanly powerful blows. During her confrontation with Winston, her intense anger enabled her to incapacitate him effortlessly, disabling both his arms and sending him flying. It is possible that Fiona's training in the mountains played a significant role in enhancing her strength to such extraordinary levels. This training likely contributed to her exceptional combat abilities, granting her tremendous power when her emotions are unleashed. However, in this state, the strength of her blows is so great that it has serious effects on her body. Every limb she used to strike Winston with broke, and even a missed punch dislocated her arm.

**Enhanced Speed and Agility:** Fiona has demonstrated to be quite nimble. She is capable of performing several acrobatics to avoid rubber bullets fired from multiple angles in the middle of an underground tennis match.

**Poker Face:** Fiona is able to conceal all of her emotions, making it impossible for anyone to tell what emotion she is feeling. At all times, she has a stone-cold look on her face, whether she is happy, upset, angry, or even proposing her love. Anya is currently the only person who knows her true nature due to her psychic powers.

**Enhanced Senses:** Fiona has good eyesight and can spot things from far away, whether it be watching someone from across a hall, noticing SSS agents stalking from behind, or detecting the little movements of a person through binoculars.

**Expert Hand-to-Hand Combatant:** After being trained by Twilight, Fiona has proven to be a formidable combatant. During an urgent mission intended for her former mentor, she was able to take on an entire enemy group by herself and is capable of slamming a man into the ground after lifting him over her head.

**Twilight:** Although this is not a skill as such, Fiona's unwavering dedication to keep fighting, her pursuit of strength, and her overall demeanor are profoundly influenced by her connection to Twilight. He serves as her primary motivation and driving force for almost everything she does. The deep attachment she feels towards him leads her to go to extraordinary lengths, even engaging in confrontations or causing harm to others if they obstruct Twilight and his ideals.

Fiona's abilities are significantly amplified when she believes she can satisfy Twilight, as demonstrated during the Campbelldon tournament, where both of them collaborated seamlessly, utilizing Loid's motivation as a driving force to achieve victory in a surprising manner, working in perfect coordination to defeat their rivals. Her devotion to him extends to an extreme level, as she would willingly make the ultimate sacrifice for his well-being. A clear example of this is seen when Winston incapacitated Twilight, and Fiona, fueled by her fierce protectiveness, delivers inhuman blows to Winston, disregarding her own safety, resulting in breaking all of her bones. Loid's presence and happiness form the foundation of Fiona's actions, pushing her to extraordinary measures to ensure his safety and fulfill his desires.

## Trivia

* Fiona's first appearance in the original release of Chapter 29 featured her with a slightly different design, with raised bangs and her right eye being visible. This was changed in the release of Volume 5, in which her current and final design was used.
* Fiona's chair, featured on the cover of the sixth volume, is a Heart Cone Chair designed by Verner Panton.
* Fiona was designed to be the direct opposite of Yor. Her design has short light hair in contrast with Yor's long dark hair. Her color scheme is also dark blue/purple and lavender in contrast with Yor's red and black. Their personalities are also opposites (cold and unwelcoming vs. warm and motherly).
* Fiona is never seen smiling outside of her (or Yor's) imagination.
	+ Fiona used to smile before Loid told her to "Bury your emotions deep."

## Quotes

* (To herself, about Loid's smile with the Forgers): *"Lionel, from the National Defense Force. Lawrence, a black market dealer, Robert, the politician's secretary. I've spent so much time studying so many Twilights. I know that masterful fake smile of his. **And I can see a tiny hint of real emotion... seeping out from beneath it.**"*
* (To herself): *"I am thankful for the rain... for hiding my emotions. Because we're spies, living in a world of shadows... because my beloved trainer taught me to... until the day that this cold war ends. But for now... even just being your cover story wife would be enough. I just want to be by your side. On our joint mission, I'll show you how capable I truly am. **I'll make you realize that I'm the only one fit to be your wife!**"*
* (To herself, after seeing Twilight's serious mode): *"There it is. That's the Twilight who won my heart. The Twilight I can't stop chasing. The Twilight I want at my side. The Twilight who turned my respect into love. The Twilight whose dreams became my dreams. What I'm saying is… I love you."*
* (To herself): *"What a wonderful man you are, Twilight. I'll achieve peace between East and West. And I’ll do it all for you."*
* (To herself): *"The moment he referred to her as just "Yor" was the moment I knew I was only gonna get his official explanation. Nevertheless, his analysis was correct. By framing it was necessary for the mission, he's made it impossible for me to object. **That was a dirty move, Twilight.**"*
