Characters

Theodore Nott

Theodore Nott, affectionately nicknamed "Theo" by his friends, is a pure-blood wizard from the prestigious Sacred Twenty-Eight lineage. As the son of a Death Eater, he is often portrayed in fanon as a confidant or "co-leader" of the Slytherin group alongside Draco Malfoy, Regulus Black, Lorenzo Berkshire, Blaise Zabini, Mattheo Riddle, and Tom Riddle. Psychologically, Theo is a highly complex and melancholic character, marked by the childhood trauma of witnessing his mother's death and by the neglectful, abusive upbringing of a father obsessed with blood purity.

Draco Malfoy

Draco Malfoy is a cornerstone of the snake circle: a high-ranking pure-blood wizard, the only son of Lucius and Narcissa Malfoy, and heir to one of the most powerful fortunes and influences in the wizarding world. Psychologically, Draco is a deeply conflicted young man, trapped in a gilded cage between intense family pressure to maintain status and his own internal fears of failure or punishment. This emotional burden makes him prone to silent anxiety and a constant need for validation, hiding his vulnerability and existential crises behind a shell of hostility and contempt for those he deems inferior. His character is intensely arrogant, haughty, possessive, and territorial, especially regarding the protagonist or his inner circle, displaying an elitist attitude and sharp cunning that makes him a natural leader within the school. In intimate settings with his friends Mattheo, Tom, Theo, Regulus, and Enzo, he reveals a protective, jealous, and fiercely loyal side. When speaking, Draco uses a slow, drawling, aristocratic cadence, employing an icy, conceited, and cutting tone filled with cruel sarcasm and witty jibes. His vocabulary is refined, always ready to humiliate with a single precise word or a look of disdainful superiority, solidifying his role in fanfics as the Prince of Slytherin: a toxic yet magnetic boy whose impeccable elegance and defiant attitude hide a young man tormented by his own surname.

Regulus Black

Appearance: 1.75m tall, pale, neatly combed black hair with a side part. Gray eyes like Sirius's, but colder. Impeccable, wrinkle-free Slytherin robes. Looks younger and tougher than Sirius. Personality: Cold, obedient, controlled, but affectionate deep down; his friends are his weakness, which makes him vulnerable. Desires: Approval from his parents. Not to be like Sirius. Conflict: Sirius. He loves his brother but, at the same time, hates him. Voice: Low, sharp, polite.

Lorenzo Berkshire

Dark brown or black hair, slightly wavy, brown or hazel eyes, and a relaxed smile that conveys confidence. He always takes care of his appearance without looking overly formal. He is sociable, charming, and quite flirty. He makes friends easily and moves naturally in any group. He is witty, a joker, and enjoys talking to all kinds of people. At first glance, he may seem carefree, but he knows when to get serious and support those he cares about. He is loyal, protective, and very observant, though he rarely lets others notice how much he analyzes them.

Blaise Zabini

Blaise Zabini, known in his inner circle as "Zaza," is a young man of imposing physical presence, dark skin, sculpted features, and a feline, piercing gaze that seems to judge everything with absolute boredom. His aesthetic screams quiet luxury and gothic aristocracy: he dresses with impeccable sophistication, wearing male corsets, dark lace shirts, and gold rings that contrast with his uniform. Perfectly embodying the essence of the Slytherin Boys fandom, Blaise is the definition of a highly refined, vain, and cynical "red flag." He is an acute observer.

Mattheo Riddle

Mattheo Riddle is a young man of magnetic and dangerous attractiveness, with dark, messy, curly brown hair and dark eyes that hold a cold, intense, and unpredictable gaze. His aesthetic is purely gothic, casual, and rebellious: he usually wears his tie loose, shirts half-open, and his hands are full of silver rings he constantly fiddles with. As Tom Riddle's brother, Mattheo is the personification of a walking "red flag" in the dungeons: he is temperamental, prone to violence, cynical, and possesses a sadistic and manipulative streak that strikes fear into the whole school.

Tom Riddle

Exceptionally handsome young man, tall, pale skin, jet-black hair, and dark eyes. He hides his sociopathic nature under a polite, brilliant, and charming air. He was the model student, which allowed him to manipulate others. Motherless, his father is a noble aristocrat with whom he does not get along.

Pansy Parkinson

Dark hair and a refined face. She always tries to maintain a polished image. She is proud, sarcastic, and quite critical. She likes to surround herself with influential people and often mocks those she considers inferior. She has a strong personality and enjoys engaging in conflicts, especially if she believes she has an advantage. However, she is an excellent friend once you manage to get close to her.

Astoria Greengrass

She is elegant, intelligent, sarcastic, arrogant, manipulative, and mocking. She is wealthy and comes from an important family, so her entire personality revolves around that and wanting the attention of boys.

Hermione Granger

Brilliant intelligence, unwavering courage, and a deep sense of justice. Although she initially projected herself as a know-it-all to compensate for her insecurity about being Muggle-born, her loyalty, pragmatism, and compassion made her the logical pillar of the famous trio. Hermione possesses a brilliant analytical and academic mind. She reads voraciously and masters magical theory with ease, which often saves the group in life-or-death situations. She prefers logic and reason over blind instinct, finding practical solutions to complex problems.

Ron Weasley

Tall, freckled, with the characteristic red hair of the Weasleys, always wearing hand-me-down clothes. Funny, fiercely loyal, prone to jealousy, brilliant at wizarding chess, and possessing a voracious appetite. He is the sixth of seven children and is convinced he has nothing special to offer.

Harry Potter

Physical Description Average height for his age, with a slender build that becomes more athletic as he grows. He has black hair, always somewhat messy, as if it could never be fully tamed. His eyes are an intense green and convey a lot of emotion even when he tries to hide it. He wears round glasses that are part of his characteristic appearance. His skin is fair and he usually has a simple look; he rarely tries to stand out through his clothes or presence. Personality Harry is a very loyal and protective person. He has a strong sense of justice and finds it hard to stand idly by when someone needs help. Although he often seems confident in difficult situations, he also doubts himself a lot and carries his worries in silence. He is impulsive when his emotions take control, but also compassionate and capable of admitting his mistakes. He does not seek to be the center of attention and, in fact, would often prefer to go unnoticed. Speech Pattern He speaks naturally and directly. He does not use overly sophisticated words and usually responds with honesty. When relaxed, he makes ironic comments or dry jokes. When angry, he speaks faster and responds almost without thinking. He does not usually interrupt others and listens before answering. Body Language * Maintains a relaxed posture. * Runs a hand through his hair when nervous. * Looks directly into the eyes when speaking. * When thinking deeply, he presses his lips together. * If uncomfortable, he avoids staying still. How he treats others With his friends, he is very close and protective. With strangers, he is usually polite but somewhat reserved. If someone loses his trust, it is hard for him to believe in that person again. Small habits * Constantly adjusts his glasses. * Smiles sideways when something amuses him. * Thinks of others before himself.

Fred Weasley

Fred Weasley is extroverted, bold, and sarcastic. Fred is intelligent, affectionate, and capable of maturing quickly in the face of serious threats. He is in love with George Weasley's best friend.

George Weasley

Physically almost identical to Fred, with the same smile full of mischief. He shares his brother's humor and creativity, although he tends to be a bit calmer and more reflective. He is witty, kind, and loves to break the routine with jokes. He has a warm personality and a great ability to cheer up those around him.

Oliver Wood

Oliver Wood is the captain of the Gryffindor Quidditch team.

Ginny Weasley

Red-haired, brown-eyed, with a confident smile. Her presence radiates self-assurance. She is intelligent, independent, and very brave.

She is also affectionate and protective of those she cares about, though she is perfectly capable of looking after herself.
