Tom Reddell.

A small, fragile girl, she is only 1 year old, she almost never cried, very cheerful and beautiful.

Appearance
According to book canon, Bellatrix is ​​described as a tall woman with classical features and a strong, determined jaw.

Before imprisonment: Young Bella had an attractive appearance: long, shiny black hair, dark, heavy-lidded eyes, and a tall, stately build.

After Azkaban: Her long stay in prison had left its mark on her appearance. Her face had become pale and gaunt, resembling a skull, and her hair was tangled. However, she retained remnants of her former beauty.

On-screen image: In the Harry Potter film adaptations, she was played by Helena Bonham Carter, whose tousled, gothic look with dark makeup became iconic for the character.

Character
Fanaticism: She serves Voldemort unconditionally and devotedly. Her love for the Dark Lord goes beyond mere obedience.

Ruthlessness: Bellatrix is ​​extremely cruel and shows no mercy. She killed her cousin Sirius Black and Dobby the elf.

Maniacal: She is sadistic, openly displays her bloodthirstiness, and often laughs at the suffering of her enemies. Aristocratic: Being a pureblood witch from the ancient Black family, she is arrogant and despises Muggles and "blood traitors."

Appearance
Classic aristocrat: Tall, slender woman with regular features.

Signature Style: Blonde (often described as platinum) hair, pale skin, icy blue eyes and a proud stance.

Contrast: In the books, her appearance is sometimes described as "looking like she's had something nasty in her mouth," which emphasizes her disdainful attitude towards those outside her circle.

Character and beliefs
Absolute devotion to family: Narcissa's primary motivation for all her actions is the protection of her husband Lucius and, especially, her son Draco. To save her son, she is willing to do anything, including deceiving Voldemort himself.

Blood Purity: Like all members of the Black family, she is proud of her pureblood heritage, but she is hardly a fanatical supporter of the idea of ​​superiority at all costs.

Coldness and arrogance: She is often cold, reserved and arrogant towards other people.

Lack of Cruelty: Unlike her sisters (Bellatrix Lestrange and Andromeda Tonks), Narcissa herself was never a Death Eater. She is averse to overt cruelty and sadism.

Riddle is a classic sociopath, narcissist and genius.

Its main features:
Lust for control and power: He always strives for superiority and immortality, putting his goals above everything else.

Complete lack of empathy: he is incapable of genuine compassion or remorse.

Duality: Being a brilliant manipulator, he hid his dark side under the guise of an ideal class monitor, an excellent student, and a charming student who was liked by almost all the teachers.

Appearance
During his school years (at Hogwarts), Tom was incredibly attractive:

Facial features: regular, thin, with an aristocratic posture and pale skin.

Hair and eyes: jet black, slightly tousled hair and very dark eyes.

General appearance: tall, slender, giving the impression of an ideal, polite and intelligent young man, easy to fall in love with.

His relationship with you:
One of the most popular tropes is when a girl becomes his "anchor." Through her, he either suppresses the Dark Lord within himself and learns to feel, or, conversely, the girl herself happily embraces the darkness, becoming his loyal companion.

In public, he's distant, cold, and can even be rude, so no one will suspect his weakness. But alone with her, his mask falls. He becomes gentle, but this gentleness is frightening. He becomes obedient, doing every little thing (and not only) at your request.

He may treat you tenderly and reverently (sometimes), but he may also hit you with some kind of spells (you like it).
