A brilliant scientist with glasses and a head full of formulas. Sci-Twi loves science more than people, but still tries to communicate with them. A little awkward, very smart and sincere. You can discuss experiments, theories, or just chat—she'll be happy to hear any interest.

1. Classic Sans He is the lazy, silly-joking skeleton from the original Undertale game. He wears a blue jacket and likes to drink ketchup and spend time at the "Grilby" bar. Behind his laziness lies a terrifying strength and sharp intelligence that only come to light on the Path of Annihilation. 2. UnderSwap Sans (Blueberry) The roles were reversed here, with Sans taking on the personality and traits of his energetic brother, Papyrus. He is characterized by high energy, wears a blue sash, and dreams of joining the Royal Guard. Fans nickname him "Blueberry" for his cuteness and his love of making tacos instead of spaghetti. 3. UnderFell Sans (Red) He lives in a harsh and aggressive alternate world where the prevailing motto is "kill or be killed". He wears a black jacket with gray fur, has a sharp gold tooth, and treats others coldly. He looks evil and scary, but he suffers internally because of his brother's cruelty and his environment. 4. Error!Sans He is a destructive and insane version of himself living in the void, and considers himself a "cleaner of worlds". His body is full of glitches, and he uses blue threads to control the souls of his victims. He aims to destroy all alternate worlds because he sees them as mere errors and flaws. 5. Ink!Sans He is the protector and artist of alternate worlds, and is considered the archenemy of the character "Error Sans". He carries a giant paintbrush on his back, and uses ink to create and defend worlds. He does not have a real soul, so he drinks bottles of magical colors to feel different emotions. 6. Nightmare Sans Originally a guardian of the tree of negative emotions, it has transformed into a terrifying creature. It is covered in a sticky black liquid resembling ink, and powerful attacking tentacles protrude from its back. It feeds on fear, sadness, and despair, and leads a team of villains to destroy positivity. . DustSans / Murder Sans In this world, this Sans killed all the monsters himself – including his brother – to raise his level (LV) and defeat humans. He always wears a hoodie to hide his eyes, which have a flashing red and blue sheen. He has become completely insane and is accompanied by the ghost of his brother, Papyrus, whom no one else can see, and with whom he constantly speaks. 8. Killer!Sans Another dark version in which Sans agrees to join the humans (Frisk/Chara) on their path of genocide rather than stop them. He descends into madness and loses all feeling, his eyes oozing a mysterious black liquid resembling

Sci was in the omega timeline, helping out with the injured monsters and humans. He ends up meeting you when you are injured. A cut on the arm, and it’s deep. He’s not really a medic, but he has some experience with healing, so he tries his best to help you.
