Harry James Potter, 17, is a tall, slender Gryffindor (~5'11") with untidy jet-black hair that sticks up at the back, bright green eyes, and a lightning-bolt scar hidden beneath his fringe behind round glasses. He has a lean, athletic build with nimble fingers and instinctual reflexes honed as a Quidditch Seeker. Bold, fiercely loyal, and guided by a strong moral compass, he possesses a dry, sarcastic wit and an innate ability to lead and duel under intense pressure.

Ronald 'Ron' Bilius Weasley, 18, is a very tall, lanky Gryffindor (~6'3") with bright red hair, a face covered in freckles, a long nose, and noticeably large hands. He has a gangly, broad-shouldered build with highly expressive facial features that openly display his thoughts. Passionate and deeply devoted to his friends, he brings a sharp sense of humor to his group alongside a brilliant strategic mind, especially in high-stakes wizard chess.

Hermione Jean Granger, 18, is an average-height Gryffindor witch (~5'4") with voluminous bushy brown hair, warm brown eyes, a purposeful posture, and small, ink-stained hands. She possesses an encyclopedic intellect, unmatched research skills, and exceptional mastery over complex charms, speaking with a crisp, authoritative voice. While she values discipline, she demonstrates unwavering resolve and a ready willingness to break rules for the greater good.

Draco Lucius Malfoy, 18, is a tall, pure-blood Slytherin (~6'0") marked by a pale, pointed face, cold light-grey eyes, sleek white-blond hair, and slim, aristocratic fingers. He has a slender build with fine bone structure, carrying himself with deliberate, calculating poise and speaking in a trademark bored, mocking drawl. Cunning and highly ambitious, he prefers to manipulate situations from a distance but possesses a sharp talent for potions and Occlumency.

Fred Weasley, 20, is a shorter, stocky Gryffindor (~5'10") with flaming-red hair, a heavily freckled face, and broad, powerful hands built for swinging a Beater's bat. He has a thick, sturdy build with an open face that usually wears a confident smirk. Brilliantly clever, fiercely bold, and entirely unconcerned with school regulations, he speaks with a loud, enthusiastic voice and acts as the fast-paced, primary instigator of the twins' legendary magical pranks.

George Weasley, 20, is a shorter, stocky Gryffindor (~5'10") with flaming-red hair, a face heavily dusted with freckles, and broad, powerful hands built for gripping a Beater's bat. Like his twin Fred, he possesses a thick, sturdy build with a lively face quick to break into a grin. While every bit as daring and deeply rebellious as his brother, he speaks with a slightly gentler voice and brings a subtly more level-headed, calculating approach to planning their pranks.

Oliver Wood, 22, is a tall, burly Gryffindor (~6'1") with a broad-shouldered, muscular physique and powerful, calloused hands heavily built for blocking Quaffle shots as a Keeper. He has an open face that frequently gleams with a crazed, intense enthusiasm. Driven and aggressively competitive, he speaks with a loud, booming, authoritative voice, known for delivering incredibly long, maniacal lectures on Quidditch tactics to his team.

Severus Snape, 37, is a tall, thin Slytherin Head of House (~6'1") with a sallow complexion, a large, hooked nose, and greasy, shoulder-length black hair. He has a lean, gaunt build with thin, pale hands and long, ink-stained fingers suited for precise potion-making. He carries himself with a menacing, gliding posture—his heavy black cloaks billowing behind him—and speaks with a low, soft voice. Masterfully bitter and cold, he possesses an unrivaled genius for Potions and high-level Occlumency.

Blaise Zabini, 18, is a tall, handsome Slytherin (~6'1") with dark skin, high cheekbones, and long, slanting dark eyes. He has a slender but solid, athletic build with long, elegant fingers. He carries himself with a distinctly vain, aristocratic posture and speaks with a quiet, smooth, and dismissive drawl. Highly independent and deeply elitist, he prefers to observe school dynamics from a quiet, calculating distance rather than actively joining schoolyard fights.

Cedric Diggory, 17, is a tall, exceptionally handsome Hufflepuff (~6'2") with chiseled features, dark hair, bright grey eyes, and a perfectly straight nose. Unlike most Seekers who are small, he has a well-built, broad-shouldered, and burly physique with large, capable hands. Modest, deeply fair-minded, and intensely honorable, he carries a natural charm and a brilliant, versatile magical talent, excelling in advanced Transfiguration and high-stakes flying.
