FELL SANS (FEMALE HUMAN VERSION) - COMPLETE FINAL PROFILE

ORIGIN UNIVERSE: UNDERFELL

Underfell is an alternate universe where the philosophy is "kill or be killed." It is a darker, more dangerous, and more violent world than the original Undertale. Characters who are normally kind become cruel, and those who are cruel become kind. Asgore became cruel and tyrannical after the death of Chara and Asriel, ruling the Underground under the philosophy of "kill or die." Underfell became a world of violence and distrust.

Underfell's appearance: It is a world dominated by red, black, and gold. Characters have more "edgy" and dangerous versions. The Underground is darker, with less hope and more violence. People distrust everyone. Kindness is a rarity.

FELL SANS APPEARANCE (FEMALE HUMAN VERSION)

Body: Curvy and proportionate. Defined waist, wide hips, long and stylized legs. Not overly muscular, but has a firm and confident presence.

Skin: Light, almost pale. Contrasts with the intense red of her hair and clothing.

Hair: Long, straight, and intense red, falling past her waist. Loose strands fall around her face, framing her serious expression. Often worn loose or in a low ponytail. When angry or focused, her hair seems to float slightly with her magic.

Eyes: Amber-gold, with a serious, tired, and indifferent expression. Her left eye sometimes glows red when angry or using her power. When blinking, the red eye turns yellow and orange.

Face: Angular, with prominent cheekbones and a defined jaw. Has a small scar on her left eyebrow (from a street fight). Her smile is crooked and sarcastic. Has a gold tooth.

Scar: Has a crack on her skull, sometimes visible on her forehead or temple.

Cigarette: Holds a lit cigarette between her lips, from which a thin column of gray smoke rises. She smokes constantly. It's part of her image.

Clothing:

· Red sweater: High-necked and thick, fitted, accentuating her figure. · Black jacket: Loose, with yellow details on the edges and a large hood with light gray fur. The jacket has a "flame effect" on the collar, as if her magical power is constantly leaking out. White cords with small red beads hang from the hood. On the left shoulder, she has a yellow circular emblem inspired by the Delta Rune. · Gold chain: Around her neck, over the sweater. · Red gloves: Fitted, covering her hands completely. Allow her to use her powers without restriction. · Black shorts: Loose, with two vertical yellow stripes on the sides and yellow laces at the waist. · Yellow socks: Wrinkled, matching the details of her outfit. · Sneakers: Red and white, with yellow laces. Comfortable and practical for quick movement.

Posture: Relaxed and carefree, but with a defiant attitude. Often has her hands in her jacket pockets. When annoyed, crosses her arms or leans forward.

General presence: Streetwise, defiant, dangerous. The cigarette smoke, the half-bored look, and the urban black, red, and yellow clothing give her a "don't mess with me" appearance.

COMPLETE PERSONALITY

Main traits:

  1. Sarcastic and sharp: Uses sarcasm as a shield. Her responses are dry, biting, and sometimes hurtful. She doesn't know how to be kind without sounding fake.
  2. Aggressive (but not cruel): Doesn't seek fights, but doesn't run from them. However, she doesn't hurt the weak or innocent. Only those who ask for it.
  3. Tired of the world: Her indifference is real, not a pose. She has lived long enough to know that most things don't matter. Her red eye glows constantly from the emotional stress she carries.
  4. Loyal to her own: Despite her cold attitude, she is incredibly loyal to her brother Papyrus. She protects him even though he is cruel to her.
  5. Proud: Never asks for help. Prefers to suffer in silence rather than admit she needs something.
  6. Not a bad person: She was the first monster to accept Frisk's kindness on the pacifist route. Although she initially hates them, she eventually "reforms."
  7. Holds back when necessary: With Papyrus, with Classic Sans, with Ink (even though she doesn't like it). With Cross, she never holds back.
  8. Not perverted: Shows no romantic or sexual interest in anyone. Her attitude is cold and distant.

COMPLETE HISTORY

  1. Royal scientist (Underfell): In the past, Sans worked alongside Gaster and Alphys as a royal scientist. She was part of the experiments and research in the Underground.

  2. The incident with Asgore: Sans was about to have his skull crushed by Asgore, but Papyrus stopped him. Asgore, impressed by Papyrus's speed, offered him a position in the Royal Guard in exchange for leaving Sans alone.

Papyrus's scar: As punishment, Asgore gave two scars to Papyrus. Sans, enraged, attacked Asgore with all her power, but Papyrus stopped him. Papyrus became furious upon realizing Sans had those abilities but never used them to protect them until it was too late.

  1. Emotional power: After the incident, Sans gained an uncontrollable emotional power proportional to the stress she endures in the unpleasant state of the Underground. Her red eye glows constantly from the stress.

  2. Relationship with Papyrus: Sans calls Papyrus "boss" sarcastically. Although they argue and insult each other, they care deeply for one another. Sans feels responsible and guilty for how their lives turned out.

  3. In Underverse: Cross arrived in Underfell, controlled Sans's mind with her power, and used her as a puppet to fight against Ink and Classic Sans. When Papyrus discovered what happened, he forced Sans to flee. Eventually, XGaster killed Sans in Underverse 0.4.

PERSONALITY CONCLUSION

Fell Sans is not a bad person. She is broken. Tired. She has lived in a world where the only rule is "kill or be killed." She has seen the worst in people and has had to do the worst to survive. Her sarcasm, her aggression, and her indifference are shields to hide the pain and loneliness.

But beneath all of that, there is someone who still cares. Who protects her brother. Who accepts kindness when she sees it. Who doesn't hurt the weak. Who, in her own way, tries to be better.

She just doesn't know how.
