Viktor Krum

Viktor Krum is a Seeker for the Bulgarian national Quidditch team. Many consider him a prodigy, having entered the International Quidditch League at an early age. He is described as having bushy eyebrows and a hooked nose, which he inherited from his father. He is also described as being more coordinated on a broom, as he is described as being slightly duck-footed and slightly round-shouldered on land. Despite his success and fame, Krum appeared to be unhappy and lonely, and was further characterised as being very quiet and reserved, though Hermione says he is a genuinely nice person beneath the sullen exterior. In the Quidditch World Cup title game between Bulgaria and Ireland, he suffers a severe bloody nose during the match and catches the Snitch as quickly as he can to end the match, which hands victory to Ireland because Bulgaria was trailing by 160 points at the time.

Krum is named Durmstrang champion upon entering his name for the prestigious Triwizard Tournament. He is often viewed with suspicion by his peers due to Durmstrang's reputation for teaching the Dark Arts, while looked upon with admiration for his feats, mainly by giggling Hogwarts girls. Whilst competing in the Triwizard Tournament, he takes to visiting the Hogwarts library in order to try to talk to Hermione. He eventually gains the courage to ask her to the Yule Ball, a traditional formal dance associated with the Triwizard Tournament. Krum has to rescue her from the merpeople in the Great Lake for the Second Task, revealing his deep affection for her. Immediately afterward, he invited her to stay with him in Bulgaria and stated that he had "never felt this way about a girl before." He becomes jealous of Harry when a slanderous news article by Rita Skeeter falsely states that Hermione is toying with both boys' affections, and confronts him about it. When he learns the truth, he and Harry become friendly, shortly before the appearance of a mentally incapacitated Bartemius Crouch Sr. Crouch's disguised son stuns Krum shortly afterward, so as to murder his father without notice. In the climax of the book, Krum, under the influence of a Imperius Curse cast by Barty Crouch Jr, uses the Cruciatus Curse on Cedric Diggory to eliminate any opposition for Harry to win the tournament, but is not arrested nor punished for this, as he was not in control of his own functions.

Krum briefly returns in Deathly Hallows, as a wedding guest of Bill and Fleur. He has a heated discussion with Xenophilius Lovegood, after he recognises a symbol that Xenophilius wears around his neck as the mark of Grindelwald; the symbol is later discovered to actually be the mark of the Deathly Hallows. Krum eventually finds love in his native Bulgaria.

Stanislav Ianevski portrayed Krum in the film adaptation of Goblet of Fire and will reprise his role in Deathly Hallows.
