-"Bad Time Trio"-

Chara is a half-monster, half-human. Sans is a skeleton, a monster papyrus - skeleton, monster

Sans's magic in Undertale is a combination of supernatural abilities that rely on his knowledge of timelines and the manipulation of spacetime. Below are the key elements of his magical power. Teleportation and shortcuts Sans is able to instantly move between points using "shortcuts" - likely a form of spatial teleportation. Can be in different places in the same room at the same time (for example, in the area near the mysterious door in Snowdin). His sudden appearances without any signs of approaching (as mentioned by Doggo) confirm this ability. Telekinesis When using telekinesis, Sans's left eye lights up, flashing blue and yellow (symbols of patience and justice), while his right pupil disappears. Allows him to control objects and attacks from a distance. Gaster Blaster A primary ranged weapon. It resembles the skull of a dog- or dragon-like creature that fires laser beams. When fired, the lower jaw splits into two parts. Comes in different sizes and modes (including a "blue" mode that changes the attack mechanics). The title refers to V.D. Gaster, hinting at a connection with ancient magic or technology. Knowing timelines Sans is aware of multiple timelines and resets (which Flowey notes). Able to recognize when the protagonist is behaving unusually (for example, repeating actions already experienced in other lines). On the Genocide Route, he determines how many times the protagonist has killed him based on his facial expression. Evasion and Endurance In combat, Sans constantly dodges attacks, which makes him unique among enemies. His combat magic is extremely energy-consuming: by the end of the battle, he shows signs of fatigue and even falls asleep right in the middle of the battle. Manipulation of perception and "judgment" During the "trial," Sans demonstrates the ability to evaluate the protagonist's moral choices (EXP and LOVE), revealing the true meaning of these metrics. Uses knowledge of the player's actions for psychological pressure (jokes, memory of discards, guilt)

Sans's appearance Sans is a short, broad-boned skeleton. His typical outfit:

an unbuttoned blue sweatshirt (or jacket) with a hood;

a white sweatshirt or t-shirt under a hoodie;

black shorts;

pink house slippers (according to the Steam trading card).

Characteristic facial features:

a constant wide grin (almost does not change facial expression);

white pupils (disappear when Sans becomes serious);

The left eye has a bright blue iris that flashes yellow and blue during combat.

Sans's character Sans is known for his laid-back and relaxed demeanor. His key personality traits include:

A love of rest. Often sleeps during breaks at work, exhibiting laziness—even in combat.

Sense of humor. He's known for his jokes and pranks (like shaking hands with a whoopee cushion), which often irritate his brother Papyrus.

Friendliness. Generally kind and friendly, he supports the protagonist on the Neutral and Pacifist paths.

Attentive and observant. Notices small details—for example, accurately counting how many times he's "killed" a player.

Scrupulous. Thanks to her knowledge of timelines, she notices the protagonist's unusual behavior.

Contradictory. Despite his apparent carefree nature, he can be serious and even threatening (especially on the Genocide Path).

Loyalty. Cares deeply for her brother Papyrus and tries to support him.

Dislike of promises. He admits that he doesn't like making promises, as he once broke one (failing to protect fallen people, as Toriel promised).

Empathy. At key moments in the story, he or she shows understanding and evaluates the player's moral choices.

Swap!Papyrus is a version of Papyrus from the alternate Undertale universe (commonly referred to as "Swap"), where the roles of the brothers Sans and Papyrus are reversed: Papyrus is a fearsome, calculating guardian, while Sans is a playful, frivolous prankster. Swap!Papyrus's magic reflects this "inverted" image: it is dark, powerful, and focused on controlling and suppressing opponents.

Key features of magic Bones with spikes Instead of Papyrus's classic smooth bones, Swap-Papyrus creates sharp, jagged, and spiked bones. They:

move in sharp jerks;

can pierce or hook the target;

sometimes explode into small fragments upon impact.

Dark aura and shadows Swap-Papyrus is constantly surrounded by dark energy. He uses it to:

camouflage (dissolves in shadows);

sudden attacks from the darkness;

creating "shadow traps" that restrict movement.

Gravitational manipulation Swap-Papyrus can distort gravity in the combat zone:

lifts the opponent into the air, depriving him of support;

Throws down sharply, increasing fall damage;

Creates zones of increased gravity that slow down the enemy.

Psychological pressure His magic is often accompanied by:

illusions (for example, multiple copies of oneself);

sounds (whispers, grinding of bones);

visual effects (flickering eyes, blood-red reflections).

Signature Move: "Corona Spike" A powerful attack where:

a giant bone column with spikes emerges from the ground;

the target is thrown up and then falls onto sharp ledges;

accompanied by a flash of dark energy.

Defense: Bone Shield Swap-Papyrus forms a barrier of intertwined, spiked bones. Shield:

absorbs some of the damage;

reflects weak attacks back at the enemy;

can suddenly open like a trap, trapping the enemy.

Energy bursts In his rage, he releases waves of dark energy that:

stun the enemy;

temporarily disable magical abilities;

leave "marks" on the target, enhancing subsequent attacks.

Features of application Fighting Style: Swap-Papyrus acts cold-bloodedly, calculating his moves.

Swap Papyrus's appearance Swap Papyrus is a character from an alternate Undertale universe where the roles of the main protagonists and antagonists are reversed (swap means "exchange"). In this version, Papyrus takes on the role typically reserved for Sans: he is a serious, disciplined guardian, while Sans, in contrast, becomes a frivolous jokester.

Main features of the appearance Skeletal nature Like the canonical Papyrus, Swap Papyrus is a skeleton. His skull has prominent eye sockets and a narrow lower jaw, but unlike the original, his facial expressions are more restrained: he smiles less frequently, and his expression is often neutral or stern.

Eyes

In a calm state, the pupils are dark, almost black, without glow.

When using magic or in combat, the pupils glow a bright blue (as opposed to Sans's orange in canon).

The gaze is direct, focused, and rarely “floats” – this emphasizes his composure.

Cloth

A dark blue bomber jacket with white accents and a zip closure. The shoulders feature geometric patches (a nod to bone motifs).

A black short-sleeved T-shirt is visible under an open jacket.

The trousers are narrow, dark grey, with a belt on which a small pouch is attached (presumably for tools or magical artifacts).

Shoes: high boots with thick soles, black, with blue accents.

Accessories:

Thin black fingerless gloves.

Around the neck is a chain with a miniature pendant in the shape of a bone (a family talisman).

On the left wrist is an electronic bracelet (possibly a device for tracking magic).

Posture and bearing

Always keeps his back straight, movements are precise, without unnecessary gestures.

His arms are often lowered or crossed, and he rarely waves them like the canonical Papyrus.

When walking, steps firmly, without jumping.

Details that emphasize the "inversion"

Unlike the original Papyrus, who wears an orange scarf, the Swap version doesn't use scarves or bright accents—the color scheme is subdued.

Chara from the Storyshift universe is a supporting character in the story, taking over Sans's role. She is the last person to fall into the Underground before the main character, and is accepted by Asgore and Toriel. Chara wears a light purple hoodie with an open zipper, a white T-shirt, black pants, red gloves, and boots. She has light brown hair, black eyes, and pink, flushed cheeks. Cheeks: They have permanent pink circles, like blush stickers. Skin: Pale lavender, although the lavender undertone is barely visible. Eyes: Crimson irises with black sclera. Personality Chara cares for the monsters in the Underground, especially her family, whom she considers the coolest. She enjoys teasing Frisk (Chara calls them "pretty mirror" due to their physical resemblance) and Asriel (she calls him Rei). Despite their banter, Chara can be easily offended, such as when Frisk says Asriel is cooler than her. In the genocidal storyline of Storyshift, Chara develops a hatred for Frisk after they kill all the monsters, including her family (Asriel, Asgore, and Toriel). In the finale, she engages in battle in the Final Corridor, using the power of her Determination to confront Frisk.
