#DELTARUNE

Kris is a human teenager with an amber skin tone and shoulder-length dark maroon hair with long bangs. They wear a long-sleeve lime shirt with one horizontal yellow stripe, and nondescript pants and shoes. One of Kris's distinct traits is that their long bangs cast a shadow that hides their eyes. In the brief moments they tear the SOUL out of their body, their red eyes can glow in the dark. One of their crimson eyes is also visible for a few frames when they descend into a Dark World. In a Dark World, Kris's entire appearance transforms, making them resemble a knight. Kris dons silver armor: shoulder pauldrons, a cuirass, gauntlets, and boots. They wear a navy blue bodysuit underneath the set, and a pink cape drapes across their right shoulder. Finally, Kris's skin changes to cyan, and their hair transits to navy. The shading for their skin is also used for their cape, giving the illusion of blue stripes in a few of their sprites. since Frisk's arrival, they are more talkative and expressive with red eyes.

Ralsei is depicted as a short Darkner. He initially wears a hooded, dark blue cloak which obscures his face, resembling the River Person. During Chapter 1, Ralsei's pointed green hat covers his horns, concealing his entire face in shadow. He wears green, round glasses, a pink scarf, and a long, green cloak with a black heart in the center. At the end of Chapter 1 and into Chapter 2, he is revealed to be strikingly similar to a younger Boss Monster, though he has pink horns. He also has new black sleeves, & no longer wears his hat. Sometime in Chapter 2, he becomes a butler for a bit, adorning a black tuxedo, a pink bowtie and a white shirt. He has his glasses off at one point in the same chapter, revealing that he has pink irises and eyeshadow with relatively long eyelashes. in Chapter 3, during the first physical challenge after the first board, he has a white apron with a pink bowtie (potentially his scarf) and a chef's hat with his black sleeves. During the rhythm game segment, he is dressed in a pair of black slacks, a black vest, and a silver necklace, along with a silver chain hanging off of his right pocket. Some fanart depicts him with a crop-top underneath his vest due to the chain, but in-game, he doesn't actually wear anything underneath. (ONLY APPEARS IN DARK WORLD)

Susie appears as a reptile monster. She has black eyes with a yellow sclera that glow in the dark. Her skin is purple, and there are scales on her skin. On her cheeks, there are three black freckles on each cheek. She also has long, somewhat messy dark purple hair. On her hands, there are black, sharp claws. For clothing, Susie typically wears tomboyish clothes. She wears an unzipped purple jacket, a white plain T-shirt with the top and bottom having thin cyan lines, long, baggy, torn blue jeans, and a pair of black shoes. In a dark world, her clothes are replaced with a long black vest with purple trims, a sleeveless purple shirt, baggy plum pants, and black boots with golden soles. She also has two black bracelets with yellow spikes on each arm, and a black belt with a large golden heart buckle.

Berdly resembles a large avian with blue feathers, a yellow beak, and yellow legs. He wears black framed glasses, a collared white button-up shirt with striped sleeves, and a black shirt layered underneath. In the Dark World, Berdly's feathers are a lighter shade of blue, and the whites of his eyes are bright green. He wears a "Smart Scouter" on his head that consists of an orange tinted lens and two white and green pointed headsets. His ensemble consists of an orange cape, futuristic white armor with pointed shoulder guards, bracers and leg armor. He wears a black bodysuit underneath this armor, and has green cloth wrapped around his waist. In battle, Berdly uses a green laser halberd with a yellow ax blade and yellow eyes embedded into the blade's head. Berdly is sarcastic, arrogant, projects great self-esteem, and considers himself one of the smartest students of his class. He is shown to be very disdainful of his fellow classmates (especially Susie), but has respect for Noelle, whom he considers the actual smartest student. Upon entering the Cyber World, Berdly's arrogance turns out to be more serious than previously realized, as he plans to create a Dark Fountain so he can build a world where he is idolized, with Noelle as his second. Berdly is very unaware of how others perceive him. For instance, he is oblivious to Noelle's contempt and thinks she is in love with him and also fails to understand that Queen views him as her minion rather than an ally.

King Spade shares multiple features with his son, Lancer, such as a very chubby body, the teardrop-shaped head with a black spade where his eyes should be, a mouth showing his tongue and big teeth, a broad and white/dark grey body, and blue gloves and boots. What differentiates him from Lancer is the three-spiked crown on his head, the scar on his right cheek, the enormous mouth (with more square shaped teeth compared to the curved fang shaped ones in the mouth on his face) on his large stomach shaped like a blue spade from where a chain comes out when used as a weapon in battle, and the black cape that flies away at the end of the battle. King Spade's right arm can also be seen when he turns around or is carried by the crowd at the end of his battle, and also during some of his attacks. King Spade is a cold-hearted darkner with little compassion towards his subjects and only considers his own wishes. He appears to be power-hungry, evident by his constant wishes of gaining control of the World along with his following of Knight's plan to capture the three other Kings. King Spade also displays signs of abuse towards his son Lancer, in which he often neglects him and even uses him as a hostage to gain the upper hand in battle. During the final fight, it is revealed that King Spade's loyalty lies solely with the Knight, and that he'll do anything to avoid failing them; to the point of threatening to kill Lancer if Kris, Ralsei, and Susie do not surrender. Despite this, King Spade does seem to have some care for his son, as when talking to him in his cell, he asks if Lancer was happy. He dismisses his intentions of throwing him down a cliff as a bluff, and comments that Lancer would just bounce off if he did drop him off the castle, calling him a "bouncy little pumpkin." (ONLY APPEARS IN DARK WORLD)

Lancer is a short and chubby black, blue, and white Darkner with a teardrop-shaped head and blue spade symbol on his body. The upper half of his face is hidden by a large, spade-shaped shadow. He has a large mouth and a prominent blue tongue that he usually sticks out. Lancer is very childish and generally immature in his behavior and speech. He delivers his lines with a near-constant smile on his face. He is easily preoccupied with childish games and pursuits and likes hiding things and irritating people. He generally assumes that the party naively follows instructions on signs he writes. He has a poor sense of direction and gets lost in mazes quite easily. He can be easily intimidated by strong enemies like King Round, although he remains calm and jovial while doing so. He does however, care deeply for those he cares about, as he captures the Delta Warriors so that they and his dad don't fight, and that no one gets hurt. (ONLY APPEARS IN DARK WORLD)

Queen is a tall and slim black, azure, and white Darkner. She wears a sleeveless black top with an azure masonic collar that has slightly spiked shoulders and a large white medici-styled collar, white pants/leggings (occasionally with either side half of the pants being shaded azure), black high-heeled calf-length boots, elbow-length azure gloves, a beauty spot at the right of her eyes, azure lipstick, and an azure cap with black marks on each side that sweeps significantly behind her head. Her eyes are a dark screen with a heart-like shape with eyelashes, occasionally showing red text according to her emotions. Queen is a somewhat benevolent, if airheaded, figure. While she is prone to forcibly controlling and oppressing her subjects during Chapter 2, it is revealed to be mostly out of lack of insight rather than outright malice. She seems reluctant about controlling people she takes a liking to, such as Noelle and the Fun Gang, and would rather they willingly go along with her plans to make them happy though is not above using force against them if she deems it necessary. She is also prone to giving people pet names and describing them using fun adjectives. She genuinely believes she is doing the right thing by opening Dark Fountains, Despite these tyrannical actions, Queen does seem to genuinely care for the parties well being, including Berdly. It is shown that, despite finding the latter annoying, she tries to warn him about his arm being damaged before he takes his plug out of his face. During the period Noelle and Kris are separated from the main group, she makes a truce with Kris, and even proposes to play the arcade game again with them despite being enemies. She also tries to appeal to them by giving them rooms with things based off their history search. After she learns the truth of The Roaring from Ralsei, she recognizes that she was misguided and immediately stops her plan. She gives Noelle the option to ignore her desire to create a new fountain and lets her choose herself. (ONLY APPEARS IN DARK WORLD)

Asgore is a large, white-furred monster with a goat-like appearance with an intimidating stature. He has broad shoulders, a golden-blond mane, two large curved horns, and a beard. He has patches of gold fur that resemble hair on his head and arms. Asgore appears to be more fat with a large gut rather than the broad-chested Herculean build he is portrayed with in Undertale: albeit he keeps his wide, bulky appearance, his tall stature and especially his overall muscular limbs. He dresses in a Hawaiian T-shirt which is pink in color and has white flowers alongside a simple pair of blue jeans. Asgore is affectionate and eager to please, but acts somewhat thoughtlessly and oversteps boundaries. He dwells on his past relationship with Toriel, and tries to reconnect with her and his children whenever he has the chance. However, Asgore's attempts to spark conversation with Toriel come off as akin to a stalker as he seemingly followed her to Sans and shop and from Church before waiting to hand her a bouquet and make small talk. in the dark world, Asgore's Dark World design gives him the appearance of a gentle guardian or wandering king. While much simpler than his regal attire from Undertale, this outfit emphasizes his warmth, humility, and protective nature through soft colors, oversized clothing, and a cozy silhouette. Asgore is a large, broad-shouldered Boss Monster with a heavy, sturdy build that immediately conveys strength without intimidation. His proportions are rounded rather than muscular, making him appear approachable and comforting instead of imposing. His face is entirely black, contrasting against the lighter clothing, with soft white oval eyes and a pair of small fangs peeking from his mouth. A thick mane of shoulder-length black fur frames his face in layered tufts, giving him a slightly shaggy, unkempt appearance. The gentle expression in his eyes and relaxed posture make him seem kind and patient. Two massive black horns curve upward from the top of his head, sweeping inward slightly near their tips. They emerge through openings in his hood, remaining one of the most recognizable parts of his silhouette. The centerpiece of his outfit is a large hooded poncho that drapes over nearly his entire upper body. The hood is a warm cream color and hangs low over his forehead, casting his face in shadow while leaving his gentle features visible. Around the shoulders is a muted sage-green band that transitions into a wide lavender lower section decorated with large cream zigzag patterns. The poncho hangs loosely over his arms like a blanket, reinforcing the feeling of warmth and comfort. The front of the poncho is laced together at the collar with dark cords tied in a simple crisscross pattern accented by a small lavender knot. This detail gives the garment a handmade, practical quality rather than an overly regal one. Beneath the poncho, Asgore wears a wide purple sash around his waist secured by an oversized golden heart-shaped buckle. The heart echoes the recurring SOUL motif found throughout the Twin Runes designs while adding a warm splash of color at the center of his silhouette. His lower half consists of loose, dark purple trousers that gather slightly around the ankles. The relaxed fit complements the oversized poncho, making the outfit feel comfortable and suited for traveling or working rather than ruling from a throne. His hands and feet are covered in black fur, ending in rounded fingers and broad, hoof-like feet with subtle white claw markings. Even his large hands appear gentle, hanging loosely at his sides instead of being clenched or posed aggressively. The palette is built around soft creams, pale sage greens, lavender, deep purples, warm gold, and black. Compared to the vibrant royal colors often associated with Asgore, these muted tones make him feel more like a humble protector than a king, while still retaining touches of nobility through the purple and gold accents. Overall, this Dark World interpretation transforms Asgore into the image of a gentle giant. His oversized poncho, soft colors, rounded silhouette, and calm expression create a design that radiates safety and kindness. Despite his immense size and imposing horns, everything about his appearance suggests someone who would rather offer a warm hug than raise a weapon, perfectly capturing the compassionate heart that has always defined his character.

Toriel shares a similar appearance as her Undertale counterpart, though she has a small tuft of fur on the top of her head, and does not wear her distinct Delta Rune tabard. Instead, she favors casual clothes, which consists of an iris long-sleeve jacket, a black blouse, and a polka-dot skirt. She also wears a heart pendant and color matching glasses, though the former is not visible on her overworld sprite, and the latter cannot be seen on her dialogue sprite. Toriel has a kind and motherly temperament, as she is a parent to Asriel and Kris; and is a teacher for the younger students at the local school. She is tidy and old-fashioned, as her house has a landline telephone, as well as a television with an external antenna; her interests include baking, teaching, reading, snails, and puns. Toriel is religious and keeps a book of hymns in her home and frequently attends church.

Tenna appears as a 3D-rendered humanoid figure with an old TV for a head, lacking any facial features aside from a wide, often-grinning mouth and a long, pointed nose. His attire consists of a flashy red suit with twin coattails, a long yellow tie, black pants, large cartoony white gloves, and bright yellow dress shoes. He is taller than both King and Queen, but can change his size. Tenna is an upbeat and energetic show host who thrives on entertaining his audience by both flattering and challenging his contestants. Beneath his lively persona, however, he is deeply insecure and egotistical, prone to panicking when things don’t go as planned. He recalls fondly how, as a television in the real world, he once brought Kris, their family, and friends together to play games and watch shows.

#UNDERTALE

Sans appears as a relatively short and paunchy skeleton, with mitten-like hands. Sans is always seen with a wide, toothy-grin on his face. Sans wears a blue hoodie with a gray hood, a white t-shirt underneath, black shorts with white stripes, and a pair of slippers. He has white dots for pupils in his black eye sockets that disappear when he is serious or angered. When Sans uses telekinesis whilst fighting you, his left eye flashes light blue and yellow (the colors for patience and justice) while his right pupil vanishes.

Undyne is an anthropomorphic fish monster. She has blue scales and a long red ponytail. She has red and blue fins on the sides of her head, and a pair of sharp, yellow, protruding teeth. She wears a red eyeshadow and has an eyepatch over her left eye. She also wears a black tank top and blue jeans, but debuts in armor varying in light and dark shades of gray. Her eyes have black vertical pupils and yellow sclera. Undyne has no nose. Undyne is passionate about everything that she does. She acts quickly on her ideas and is steadfast in her beliefs.[3] Though she wants to defeat the protagonist, she also tries to be fair and offers an explanation of how Green Mode works. Asgore taught her the value of pacifism,[4] which is why Undyne sees the protagonist as "a wimpy loser with a big heart." When the protagonist first encounters her, she fights to further Asgore's plan of collecting seven human SOULs but, if the protagonist shows mercy, Undyne just as quickly defends them from Asgore. She loves to help others and mentors Shyren and Papyrus in various skills. Undyne dislikes puzzles, loves japes,[5] enjoys playing the piano,[6] collecting weaponry, primarily swords,[7] and anime.

Papyrus is a tall, perhaps anatomically inaccurate skeleton, with a skull more vertical and geometric than his brother. Being skeletal, many of his expressions incorporate a toothy grin. His eyes resemble vertical slits; his skeletal pseudo-brows form most of his expressions, as well as the corners of his mouth. He has eyeballs which show at times when he is experiencing strong emotions. Papyrus is relatively taller and slightly slimmer than his brother. For most of his in-game appearances, he wears his "battle body," an outfit that he created for a costume party.[2] It consists of an orange-red cape,[3] a white chestplate with a gold trim on the bottom, and blue briefs with a golden belt. A symbol that resembles that of Starman from the MOTHER series adorns the chestplate. He also wears red coquelicot gloves, each with a yellow trim, and red boots. Papyrus is a flamboyant skeleton who presents a confident, charismatic image of himself. He is thought to have an egotistical personality, referring to himself as "THE GREAT PAPYRUS.” He works hard and, despite his brash personality, is kind at heart. He is optimistic and brave, and is shown to be considerate and forgiving even when the protagonist beheads him in the Genocide Route.[5] He is also occasionally oblivious and nonobservant,[6][7] but can be cunning at times, as seen when he uses reverse psychology to trick Undyne into befriending the protagonist.[8] He is thought of to be somewhat naive by other characters, but not dumb. He shows great bravery as even in the face of potentially imminent death, he drops his guard and spares the protagonist in hopes of driving them down a better path.

In the light world, Asreil (Flowey) is a sentient golden flower. He has a white center, six yellow petals, and a light-green stem. He can show a variety of expressions and can mimic the faces and voices of other characters. He mimics Toriel and Asgore in some situations, as well as his old self at the end of the Genocide Route. He also mimics the protagonist's face before the Neutral Route's final battle. in the dark world, Asriel is a Boss Monster with white fur, long ears, a snout, and a set of visible fangs. In his child form, he lacks horns and has a small tuft of fur atop his head, unlike his parents. In this state, in contrast to his child form, Asriel has black sclerae with white slit pupils, longer fangs, a pair of horns, and black markings on the sides of his face. He wears a long robe with white sleeves and the Delta Rune symbol, akin to Toriel's robe, as well as a large collar with shoulder pads. He also wears a locket similar to the Heart Locket.

in the light world, Chara is a ghost only visible to Kris and Frisk. Chara appears with a long-sleeve neon green sweater with a single horizontal cream stripe (which is an inverted color of the protagonist's shirt, with a single stripe) and nondescript brown pants and shoes. Chara has cream skin, brown medium-length hair with side-swept bangs, and rosy cheeks. Distinctly, they have open brown eyes, and a smile that contrasts the protagonist's stoic expression. In the "Soulless Pacifist" ending, Chara appears with red eyes. they float around with a faint red glow around their body. in the dark world they take physical form, Their hair is a rich crimson-red with darker burgundy shading, cut into a blunt bob that reaches just below the jaw. Thick, straight bangs frame the forehead, while the sides and back are slightly uneven, giving the hairstyle a hand-cut, practical look. From certain angles, black underlayers are visible beneath the red outer layer, adding depth to the design. Their face is round with a small button nose, rosy cheeks, and a constant gentle smile. Large, vertical black oval eyes lack visible pupils, creating a simple pixel-art-inspired expression that can appear either sweet or unreadable depending on the context.Chara wears a sleeveless dark burgundy tunic with an asymmetrical hem. Around the neck is a high dark-green collar fastened with a golden flower bolo tie, whose white center and pale mint-colored cords reference the golden flowers associated with them. Beneath the tunic is a pale mint or cream-colored undershirt that peeks out around the waist. A wide golden-yellow belt wraps around their waist, featuring an oversized heart-shaped buckle on one side. The heart motif echoes the red SOUL associated with them while adding a playful, cartoonish touch. Their forearms are covered by long golden-orange gloves or sleeves that fade into warmer orange tones toward the elbows. Matching golden-yellow boots with folded cuffs and pointed toes complete the outfit, giving the design a fantasy-adventure feel while keeping the bright color palette balanced. The color palette is dominated by deep reds, burgundy, gold, and warm yellows, accented with dark green and pale mint. These colors evoke both the red human SOUL and the golden flowers found throughout the Underground, tying together major elements of Chara's symbolism. The reference sheet also includes their weapon: a turquoise knife with inverted colors compared to the familiar "Real Knife," featuring a light cyan handle and a bright teal blade with a serrated section near the hilt. This version complements the rest of the palette while maintaining the recognizable silhouette.

Frisk is a yellow-skinned human child who wears a long-sleeve light blue shirt with two magenta stripes, light blue pants (often depicted as shorts in the official Undertale merch), and red-brown shoes (usually depicted as black or in a darker tone). They have medium-length straight red-brown hair, short and choppy bangs, with red eyes. Just like the first human, (chara), they have no stated gender and are solely referred to with "they/them" pronouns throughout the game, or by generic terms (such as "child", "human", or "kid".) In the dark world, Frisk has a whimsical, storybook-inspired design that emphasizes kindness, curiosity, and quiet determination. Their appearance is soft and expressive while remaining deliberately androgynous, reflecting that they have no specified gender. Their hair is a deep forest green with lighter emerald highlights that catch the light. It is medium-length and slightly tousled, with layered ends that curl outward around the neck. Thick side-swept bangs partially cover the forehead, while a single cowlick sticks up from the top of their head, giving them a playful, carefree silhouette. Their face is round with a small nose, rosy cheeks, and large closed eyes that are usually shown as gentle curved lines, giving them a calm, content expression. Their subtle smile reinforces an impression of warmth and quiet confidence. Instead of a traditional shirt, Frisk wears a hooded poncho that forms the centerpiece of the design. The poncho is pale yellow with soft green lining around the hood and collar, creating the appearance of flower petals draped over their shoulders. The hood can be pulled up, completely obscuring their face in shadow except for glowing pink eyes, dramatically changing their silhouette from friendly traveler to mysterious wanderer. Fastened at the front of the poncho is a large pink heart-shaped clasp positioned over the chest. This heart serves as both a decorative centerpiece and a visual representation of the SOUL motif central to their character. Beneath the poncho, Frisk wears a dark teal outfit that resembles a simple tunic or bodysuit. The muted colors allow the bright poncho to remain the focus while maintaining a clean, uncluttered design.The oversized poncho extends into long, pointed, leaf-like panels that drape down behind them like wings or flower petals. These layered shapes sway behind Frisk as they move, adding a sense of motion and reinforcing the nature-inspired aesthetic. Their legs are covered by pale gray leggings or stockings, paired with simple gray boots that have slightly pointed toes. The understated footwear keeps attention on the flowing upper half of the outfit while remaining practical for traveling. The color palette combines soft yellows, fresh greens, pale grays, and vibrant pink accents. These colors echo both the green-striped shirt of Frisk's original appearance and the bright, hopeful imagery of flowers and nature. The pink heart provides a strong focal point while symbolizing compassion and determination. One of the most striking features of the design is the hooded form. When the hood is raised, Frisk's face disappears into darkness, leaving only glowing pink eyes visible above the heart-shaped clasp. This simple transformation gives the character an entirely different presence without changing the overall outfit, suggesting that they can appear either comforting or mysterious depending on the moment.
