Appearance

Snape is a pale, black-eyed wizard known for his severe black robes, shoulder-length greasy black hair, and prominent aquiline nose. Before his later enhancements, Kyle could exhaust him simply by leading him on a chase through Hogwarts. 85 532 616

• Usually wears voluminous black robes that trail behind him like bat wings. 17 532
• Carries himself with an oppressive, intimidating presence that clears corridors and silences students. 85
• After unlocking the Hallows, wears a tattered black Death God Cloak and wields a pitch-black staff. 603 685
• After absorbing the Ten-Tails, his hair becomes waist-length and white; his robe is restored into an ornate black garment marked with the Deathly Hallows symbol, while nine spheres orbit behind him. 701

Personality

Snape is cold, guarded, and deeply sarcastic. He dislikes being manipulated by Dumbledore, resents Kyle's constant provocations, and initially refuses to serve as Kyle's teacher; Dumbledore ultimately pressures him into accepting the duty. 17

His defining motivation is Lily Potter. Her death drives his protection of Harry, his hatred of Voldemort and Peter Pettigrew, and his increasingly extreme attempts to breach the boundary between life and death. Even while working among Death Eaters, he pursues a plan centered on resurrecting Lily rather than serving Voldemort. 101 279 484 604

Snape is cautious around people whose promises appeal too directly to his desire. He refuses Slytherin's offers of partnership and regards the founder's resurrection claims with suspicion, though his fixation on Lily ultimately leaves him vulnerable to Slytherin's betrayal. 549 604 643 701

Abilities & Skills

Potions Mastery

Snape is an exceptional potion-maker, able to devise advanced ingredient-processing techniques and brew rare potions such as Felix Felicis.

• Teaches Kyle advanced processing methods not found in the standard Potions textbook. 87
• Uses potions to treat severe injuries inflicted by Voldemort's traps. 123
• Successfully neutralizes a poison made by Voldemort after roughly twenty days of work. 436
• Secretly administers altered potions to Voldemort while ostensibly treating him. 484 568

Dark Arts and Combat Magic

Snape is a highly capable dark wizard whose combat style combines lethal curses, battlefield control, and deception.

• Kills Peter Pettigrew with Avada Kedavra and alters the accompanying Aurors' memories before placing them under the Imperius Curse. 279
• Uses Sectumsempra, Serpensortia, Fiendfyre, Incarcerous, and other combat spells against James Potter. 697
• Creates black rods through the Elder Wand that disrupt magical power and immobilize targets, including Impure World Reincarnation bodies. 698 700
• Uses Occlumency to suppress his emotions and maintain composure under pressure. 131 685

Impure World Reincarnation

Using the Resurrection Stone, Snape develops an undead-reanimation method intended to restore the dead and place them under his command.

• Creates an Impure World Army from the remains of deceased wizards. 437 579
• Reanimates Ignotus Peverell, Cadmus Peverell, James Potter, and multiple former Death Eaters. 437 634 678
• Builds his forces through systematic grave robbing, seeking remains suitable for further reanimation. 579
• Directs an army of at least fifty thousand undead wizards through the controlled Ōtsutsuki Voldemort. 669

Cursed Seal

Snape develops the Cursed Seal as a method of enforcing obedience on resurrected or empowered subjects.

• Engraves controlling runes on a target's head to erase their will and turn them into puppets. 243
• Uses the Resurrection Stone to grant Little Barty Crouch Jr. a major increase in magical power. 598
• Enhances Little Barty with the Cursed Seal of Earth, though Snape later judges the amplification insufficient and seeks improvements. 642 643

Deathly Hallows

Snape's greatest power comes from unsealing and combining the three Deathly Hallows.

• Resurrection Stone — connects him to the Underworld, supplies immense magical power, enables reanimation, and serves as the core of his attempts to revive Lily. 329 536
• Death God Cloak — absorbs magical-energy attacks, grants extraordinary defense and physical enhancement, and rapidly aids recovery; it does not protect against physical damage. 615 696
• Elder Wand / Heart Sword — transforms into a black staff after unsealing and dramatically amplifies offensive power; before accepting Snape as master, it resists him and makes his spellcasting unstable. 603 615
• Snape becomes capable of drawing upon Underworld power even without the Resurrection Stone nearby after the Elder Wand recognizes him. 701

Physical Enhancement

Snape compensates for his earlier lack of fitness through Hallows-based enhancement and personal research.

• His original physical condition is poor enough that chasing Kyle leaves him gasping and unable to catch him. 85
• The Death God Cloak later raises his physical strength, speed, and resilience far beyond ordinary human limits. 610 615
• Researches methods to improve his own wandless, artifact-independent combat strength rather than relying solely on the Hallows. 682

Equipment / Weapons / Items

• Resurrection Stone — centerpiece of his Underworld magic, reanimation research, and plan to revive Lily. 226 536
• Elder Wand / Heart Sword — unsealed into a pitch-black Zen staff-like weapon. 603
• Death God Cloak — the unsealed form of the Invisibility Cloak; absorbs magical attacks. 603 615
• Philosopher's Stone — borrowed and repeatedly recharged to erode the Resurrection Stone's seals. 226 536
• Crystal sarcophagus containing Voldemort's corpse — used to modify Voldemort into a conduit for Underworld power. 616 633
• Felix Felicis — offers a vial in exchange for information concerning the Resurrection Stone. 85

Relationships

• Albus Dumbledore — Headmaster, reluctant ally, and frequent adversary in ideology. Dumbledore forces Snape to mentor Kyle and later relies on him as a double agent; Snape blames him for failing to protect Lily and eventually defeats him to gain the Elder Wand. 17 101 438 700
• Lily Potter — Snape's childhood friend and enduring love. Her death is the central motive behind his protection of Harry, pursuit of the Deathly Hallows, and resurrection research. 21 101 604
• Harry Potter — Lily's son. Snape protects him under his agreement with Dumbledore, teaches him Occlumency, later serves as his defense counsel, and eventually brings the unconscious Harry to Spinner's End. 101 507 519 668
• Kyle Dumbledore — student, unwanted apprentice, and eventual enemy. Snape teaches Kyle Potions despite mutual irritation; Kyle later battles Snape and tries to stop his control of Voldemort. 17 87 597 610
• Voldemort — former master and target of Snape's revenge. Snape secretly poisons and manipulates him, kills him by removing his heart, then modifies his corpse into Ōtsutsuki Voldemort. 484 598 616
• Lucius Malfoy — Shell co-conspirator. Snape coerces Lucius into cooperation through knowledge of Voldemort's Horcruxes and binds their partnership with an Unbreakable Vow. 188 255
• Salazar Slytherin — ancient founder accidentally summoned through the Resurrection Stone. Slytherin repeatedly tries to recruit Snape before ultimately stealing the Resurrection Stone and Snape's power. 536 604 701
• James Potter — longtime rival and Lily's husband. Snape attacks him on sight after James's reanimation; their later duel ends with Snape overpowering and pinning James. 694 698
• Peter Pettigrew — hated for his role in Lily's death. Snape intercepts his transport to Azkaban and personally executes him. 279
• Little Barty Crouch Jr. — empowered subordinate who later turns against Snape after studying his Deathly Hallows and Underworld magic. Snape kills him during their confrontation. 598 698 700

Story Role / Major Arcs

Hogwarts Professor

Snape begins as Hogwarts' Potions Master and Head of Slytherin House, maintaining a feared reputation among students. He takes over Defense Against the Dark Arts after Tom Hiddleston's arrest and later teaches the practical Magical Offense and Defense course, dismissing conventional textbooks in favor of direct combat training. 24 532 533

Dumbledore presses him into mentoring Kyle because he fears Kyle could become another Grindelwald. Snape reluctantly teaches Kyle Potions, starting with the unpleasant fundamentals of preparing animal and plant ingredients. 17 87

Resurrection Stone and the Shell Organization

Driven by the hope of restoring Lily, Snape acquires the Resurrection Stone and investigates its seals. He concludes that the Stone's ordinary soul projections are an incomplete expression of its true power and begins searching for a way to break the restrictions. 131 226

He recruits Lucius Malfoy into the secret Shell organization, using Voldemort's Horcruxes and Lucius's fear to force his compliance. Shell is intended to operate within the Death Eaters while ultimately freeing its members from Voldemort's control. 188

Double Agent and Dark Lord's Betrayal

While remaining embedded among the Death Eaters, Snape reports to Dumbledore and works against Voldemort from within. He secretly poisons Voldemort, prepares a plan to use his corpse as a vessel, and abandons any expectation that Voldemort will help secure the Elder Wand. 438 484

Snape finally freezes Voldemort, takes control of his body with black runes, removes his heart, and converts him into a puppet. He then uses the Resurrection Stone to empower Little Barty and leaves the battlefield with Voldemort's body. 597 598

Deathly Hallows War

After unsealing all three Hallows, Snape emerges as a new Dark Lord whose power forces the wider magical world into open conflict. He relies on the Death God Cloak's defense, the Resurrection Stone's Underworld magic, and the Elder Wand's offense to fight Kyle, Dumbledore, Grindelwald, and their allies. 603 609 615

He transforms Voldemort's corpse into Ōtsutsuki Voldemort, uses it to raise a massive undead army, and attempts to create a body capable of channeling greater Underworld power than his own human body can withstand. 633 668 669

Fall of Snape's Ascendancy

Snape defeats Dumbledore and gains the Elder Wand's allegiance, then absorbs the Ten-Tails and believes he is finally capable of ending the war and reviving Lily. 700 701

His triumph is immediately undermined by Slytherin, who emerges through the Resurrection Stone, pierces Snape's chest, and takes the Stone for himself. Snape's apparent control over Death is revealed to have been temporary access to the Hallows' power rather than true ownership. 701 702
