Hogwarts

Noble and honest. He demonstrated this when he wanted to replay a Quidditch match because Harry had fainted, and later assisted Harry in the Triwizard Tournament in gratitude for his help.
Modest and quiet. A man of few words, he didn't seek glory, despite being the team captain and one of the strongest Hufflepuff students.
Brave, but without ostentatious bravado. He calmly accepted the challenges of the Tournament and held his own even in mortal danger.

Peter Pettigrew (Wormtail)
Cowardly and dependent. Constantly seeking a patron: first he stuck with the Marauders, then he joined Voldemort. His primary motivation is survival at any cost.
Treacherous and calculating. He revealed the Potters' location to Voldemort and later faked his own death, framing Sirius Black.
Morally weak, but cunning. Capable of underhanded actions when it helps him save himself; however, he has almost no inner strength and easily breaks under pressure.

A wise, kind mentor, yet complex and ambiguous. His past is tainted by dark pages (his affair with Grindelwald), and he's willing to use cunning and manipulation for the greater good.

Cheerful, cheeky, and fond of pranks, they're also courageous and devoted to their family. Their humor is a way to fight injustice (like the rebellion against Umbridge), and their shop, "Weasleys' Wizard Wheezes," is a manifestation of their ingenuity and entrepreneurial spirit.

From a shy girl, she transforms into a confident, determined witch: bold, independent, with a bright sense of humor. She excels at Quidditch, masters the corporeal Patronus early, and acts with composure in battle.

A rebel and a devoted friend: fiercely loyal to those he loves (James, Harry), but impulsive and often driven by emotion. His break with the Black family is a conscious rejection of their values, making him free-spirited and outspoken.

Calculating and reserved, her primary motive is to protect her son. She's willing to break her allegiance to Voldemort for Draco (a lie in Deathly Hallows). Cold on the outside, but utterly decisive when it comes to family.

Aristocratic, arrogant, and politically cunning. Accustomed to relying on status and connections, he is loyal to Voldemort more out of calculation and fear than fanaticism; when his influence fades, he becomes cruel and desperate.

Pragmatic and cautious, he prefers not to take unnecessary risks. He often comments on events with irony, maintains a detached demeanor, and does not strive for leadership.

Withdrawn, observant, and intellectual, he keeps to himself, is cynical, and not prone to blind obedience, but shares the values ​​of pureblood families without Bellatrix's extremes.

Fanatical, cruel, theatrically furious, she serves Voldemort with an almost religious fervor and takes pleasure in violence. She embodies the extreme form of Black pride and contempt for those she considers inferior.

Kind, sensitive, fair; as a teacher, he knows how to inspire (a lesson with a Boggart). Prone to self-denial due to lycanthropy, he long considers himself a danger to others, but eventually learns to accept love and responsibility.

Sarcastic, conformist: she adheres to a strong group (primarily Draco's group) and expresses collective contempt for "outsiders" through ridicule. Her aggression is a way to maintain status within her circle.
