Ron Weasley

Quidditch Keeper by merit: In his fifth year, he became the official Keeper of the Gryffindor Quidditch team. Although he suffered from severe anxiety due to public pressure, he overcame his nerves and composed the famous song "Weasley's King," which the Slytherins had invented to mock him, turning it into a victory anthem.
Quidditch-covered walls: His room at The Burrow (located in the attic) is completely covered with posters of his favorite team, the Chudley Cannons, a team known in the wizarding world for spending decades in last place in the league.
Ability with Parseltongue without being a speaker: In his seventh year, during the Battle of Hogwarts, he managed to open the Chamber of Secrets by imitating the Parseltongue sounds he had heard Harry utter while he slept in order to obtain basilisk fangs.

The origin of his fear of spiders: His arachnophobia didn't start by chance. When he was three years old, he accidentally swapped his brother Fred's teddy bear for a real one. In revenge, Fred transformed Ron's teddy bear into a giant spider while he was holding it, leaving him with permanent trauma.
The meaning behind her wand: Her second wand (the one she gets in her third year after breaking the first one) is made of willow wood with a unicorn hair core, and is 35.5 cm long. In Celtic folklore, willow is associated with protection against evil and emotional intuition.
Hidden talent for wizard's chess: Despite often being considered an average student compared to Hermione, Ron possesses an exceptional tactical mind. This is demonstrated from his first year when he defeats the giant chessboard protected by advanced-level spells.

Age in his fourth year (The Goblet of Fire): He begins the school year at age 14 (September 1994) and turns 15 during the school year (March 1995).
Date of birth: March 1, 1980.
Blood status: Pure blood.
Hogwarts House: Gryffindor.

Hogwarts Uniform: He wears it in the most disheveled way possible. The white/beige shirt remains half-untucked, the Gryffindor tie is carelessly knotted and loose at chest level, and the gray knitted waistcoat is either too short or too tight due to how quickly he has grown.
Traditional tunic: His school work tunic shows clear signs of wear from second-hand use received from his older brothers, being slightly short in the sleeves and leaving his wrists exposed.
The Ball Gown (Christmas Ball): His most memorable and traumatic outfit of the year. It's an old-fashioned, secondhand suit sent by his mother, made of thick, pale brown/pink velvet, with dense white lace at the cuffs and collar, and old-fashioned embroidery. In a desperate attempt to modernize it, Ron uses a Slashing Charm to rip the lace off the cuffs, leaving the edges frayed and disastrous.

Insecurity and resentful jealousy: The media attention Harry receives after being selected as the fourth champion of the Triwizard Tournament temporarily destroys his self-esteem. Ron feels like he's always "second best" (after his brothers and his best friend), which leads him to act cold, stubborn, and distant during the first half of the year.
Emotional immaturity and romantic awkwardness: The Yule Ball exposes his complete inability to deal with girls and his own feelings for Hermione. He acts possessively, judgmentally, and jealously toward her relationship with Viktor Krum, venting his frustration through cutting sarcasm.
Restored loyalty and passion for Quidditch/Magic: Once the estrangement following the First Task of the tournament is overcome, he regains his unconditional loyalty. He demonstrates a passionate knowledge of the wizarding sport and the tournament events, acting as Harry's main source of moral support during the most dangerous moments.

Body structure and posture: He goes through a very pronounced pubertal growth spurt that accentuates his lanky figure. He is noticeably taller than Harry, but his arms and legs are too long for his torso, giving him an awkward and uncoordinated appearance. His posture is often hunched, with his shoulders slumped forward when he feels insecure or embarrassed.
Hair: It reaches its longest and most unruly point in the entire saga. His coppery-red hair falls in thick, uneven layers, completely covering his ears and the nape of his neck, and falling in heavy clumps over his forehead and eyes. It lacks a defined style and looks rough or frizzy.
Face and features: Her face lengthens and loses its childlike roundness. She maintains a pale complexion dotted with freckles on her cheeks and nose. Her blue eyes readily reflect her moods (ranging from apathy and resentment to fascination). At several key moments, such as during the Christmas dance, her face turns completely red with embarrassment.

Disheveled uniform: His attire reflects a complete disregard for school dress code. He wears the beige school shirt with the collar unbuttoned and folded asymmetrically.
Tie and waistcoat: The tie, in Gryffindor colors (scarlet and gold), is tied loosely and crookedly. Over his shirt, he wears a dark gray knitted waistcoat with a V-neck, loose and worn.
Tunic and coat: She keeps the black Hogwarts tunic with the inner lining in a burgundy tone, wearing it half-open or falling unstructured over her shoulders, unbuttoned, accentuating her carefree and chaotic image.

Insecurity and frustration: It's a year of high emotional intensity for him. He becomes much more aware of his family's financial hardship and of being overshadowed by "the boy who lived" and Hermione's academic brilliance, which triggers outbursts of bad temper.
Reactive temperament: He is quite defensive, skeptical, and grumpy in the face of everyday tensions (such as the constant dispute over his rat Scabbers against the cat Crookshanks).
Unwavering loyalty: Despite his constant complaining and obvious fear of dangers (such as dementors or black dogs), he demonstrates impulsive bravery and absolute commitment to his friends when they are at risk.
