Background / History

Snape was a Hogwarts student noted for exceptional talent in potions. During his school years, he refined the sixth-year Potions textbook and developed formidable one-on-one dueling ability; he was also involved in a long-running conflict with James Potter and his friends. 30 86

He was once among Voldemort's trusted Death Eaters alongside Lucius Malfoy and Bellatrix Lestrange, but later defected to Dumbledore's side. After Horace Slughorn resigned following Voldemort's downfall, Snape became Hogwarts' Potions Professor and Head of Slytherin. 75 130 174

Before Gemini Fox enrolled, Dumbledore sent Snape to investigate Gemini's assault on Marcus Flint. Although Snape initially threatened expulsion, he accepted that Flint had provoked the conflict by using the slur “Mudblood” and left Gemini unpunished. 16

Appearance

Snape is a tall man who habitually wears black robes. His long black hair is slicked back, and his cold stare is repeatedly emphasized. 16

• Slick, long black hair
• Black robes
• Tall, severe silhouette
• Cold, penetrating gaze 16

Personality

Snape is stern, sarcastic, and quick to anger, particularly when students challenge his authority or exploit his words. His usual response to unwanted questions is some variation of ordering the speaker to leave. 16 26 58

He sets demanding academic standards and openly favors achievement, especially from Slytherin students. He praises Gemini's intelligence, defensive skill, and quick reactions, while routinely humiliating Harry and penalizing Gryffindor. 28 30 31 52

Despite his hostility, Snape takes his responsibilities seriously. He warns Gemini to avoid attracting dangerous attention, privately trains him in advanced magic, and is described as willing to answer even Neville Longbottom's questions outside class. 26 36 174

Abilities & Skills

Dueling and Defensive Magic

• Countered Gemini's summoned birds with a ring of fire. 28
• Avoided Gemini's improvised blackboard attack and was only disarmed after being caught off guard. 28

Silent Spells

• Instructs Gemini to cast a silent Disarming Charm at a practice dummy. 36
• Schedules private Saturday-evening training sessions for Gemini. 36
• Uses silent casting efficiently enough that spoken incantations are treated as a significant disadvantage in a duel. 36

Dark Magic Knowledge

Snape possesses substantial knowledge of dangerous magic but is reluctant to pass it on indiscriminately. 58 202

• Identifies Fiendfyre as capable of completely annihilating Dementors. 58

Relationships

• Albus Dumbledore — Employer and ally. Dumbledore entrusts Snape with disciplinary matters and relies on his loyalty; Snape later observes Gemini's duel with Dumbledore. 16 45 118

• Harry Potter — Student whom Snape openly antagonizes. He quizzes Harry harshly, compares him unfavorably with Gemini, and provokes him into a duel. 30 52 214
• Voldemort — Former trusted Death Eater associate. Snape later defects to Dumbledore, making his past allegiance a source of distrust and ambiguity. 130 174

• Gilderoy Lockhart — Dueling Club opponent. Snape visibly detests Lockhart and humiliates him with Expelliarmus. 107
• Neville Longbottom — A frequently intimidated Potions student. Snape is harsh toward Neville but acknowledges his serious aptitude for Herbology. 141 204

Story Role / Major Arcs

Flint Incident and Gemini's Sorting

Snape investigates Gemini's attack on Marcus Flint before the school year begins. He threatens Gemini with expulsion, but the accusation of “Mudblood” changes his assessment of the incident. 16

Gemini's eventual sorting into Slytherin visibly displeases Snape, who had previously said he would rather surrender his Head of House position than accept Gemini as a Slytherin. 16 24

Gemini's First-Year Mentor

As Gemini's Head of House, Snape advises him to keep a low profile because dangerous wizards may target an unusually gifted student. 26

He tests Gemini's defensive magic, is disarmed by him during their first office duel, and nonetheless sincerely praises Gemini's strategy and humility. 28

Snape later provides private instruction in Silent Spells and supervises Gemini's failed attempts to cast a Patronus. 36 40 58

Defense Against the Dark Arts Substitute

After Quirrell is sent to Azkaban, Snape takes over Defense Against the Dark Arts for first-years and demonstrates unusual enthusiasm for the subject. 46

His instruction remains closely tied to practical survival: he discusses methods of avoiding Dementors, recommends Occlumency and Animagus transformation for concealment, and warns Gemini against learning Fiendfyre. 58

Escalating Training Difficulties

As Gemini gains chakra-based techniques, shadow clones, substitutions, and other non-magical combat abilities, Snape becomes increasingly frustrated that his student is not focusing solely on magic. 117

After repeatedly being overwhelmed during practice, Snape expels Gemini from his office and directs him to seek Dumbledore as a sparring partner instead. 117

Later School Years

Snape remains involved in Hogwarts discipline and Slytherin affairs, issuing the team a special Quidditch-pitch training pass and questioning Gemini after he forfeits a match for using his Magic Eye. 92 144

During Lupin's tenure, Snape reacts badly to Neville's Boggart taking the form of a drunken version of him. He is later rumored to be the next Defense Against the Dark Arts professor after Lupin's planned resignation. 141 174

In Gemini's fourth year, Snape is unsettled by the disguised Barty Crouch Jr. posing as Mad-Eye Moody and becomes noticeably irritable around him. 201
