Background

Jericho is an American wizard from the Blench family, described as a sporting family. His father, James Branch, is Director of the Magical Sports and Games Department of the Magical Congress of the United States of America. Jericho persuaded his father to visit Britain ahead of the Quidditch World Cup, helping create an opportunity for cooperation between his family and Moriarty. 31 81

He came to Britain specifically because Moriarty was at Hogwarts, later admitting that he would not otherwise have enrolled there. At school, he quickly became one of Moriarty’s closest Slytherin companions, studying, flying, competing, and fighting alongside him. 144 328

Early in his first year, Jericho tampered with Keith’s broom after becoming desperate to fly freely. The incident nearly caused a fatal accident; after Moriarty confronted him, Jericho publicly confessed, apologized to Keith and Percy, accepted detention, and lost House points. 31 32

Appearance

Jericho is a short-blond-haired American wizard who later grows taller, leaner, and more tanned while living in Texas. 85 81 593

• Often adopts a conspicuous cowboy style, including a leather jacket, wide-brimmed felt hat, revolver, and spurred boots. 593
• Wore a bright red leather jacket and white hiking boots while traveling in Japan. 285
• Uses custom Quidditch equipment, including a silver-and-green broom engraved with “MS” and bearing Moriarty’s portrait. 563

Personality

Jericho is energetic, competitive, theatrical, and strongly drawn to attention. He enjoys performing before a crowd, calling himself the “Swift Kid,” but distinguishes admiration from being treated like a spectacle. 195 His confidence can become arrogance, particularly when he believes his athletic ability or combat skill makes him indispensable. 142 312 338

He is also quick-witted and observant. Jericho recognized Moriarty and Lilith despite their altered identities by tracing travel records, sensed Habane Hotaka’s suspicious nature by instinct, and deliberately pretended to fall into Habane’s trap in order to gather information. 285 337 365

Although impulsive, he can acknowledge fault after being confronted. His apology over Keith’s broom incident and his humiliation after losing to Duwayne force him to reflect on his conduct and limits. 32 312

Jericho’s central motivation is his loyalty to Moriarty. He wants to travel the world with him, repeatedly seeks opportunities to prove himself at Moriarty’s side, and ultimately commits himself to defeating the Immortality Organization. 107 142 718

Jericho is an elite flyer and Slytherin’s Chaser. He was selected for the house team alongside Moriarty after demonstrating his flying ability, and he combines competitive Quidditch techniques with combat movement. 25 26 289

Spellcasting and Dueling
