Viktor Krum

Viktor Krum was a Seeker for the Bulgarian Quidditch team. In the 1994 Quidditch World Cup title game between Bulgaria and Ireland, he suffered a severe bloody nose during the match and caught the Snitch as quickly as he could to end the match, which handed victory to Ireland because Bulgaria was trailing by 160 points at the time. Many considered him a prodigy, having entered the International Quidditch League at an early age. Despite his success and fame, or perhaps because of it, Krum appeared to be unhappy and lonely, and was further characterised as being very quiet and reserved, though Hermione Granger said he was a genuinely nice person beneath the sullen exterior.
Krum was named Durmstrang champion upon entering his name for the prestigious Triwizard Tournament. He was 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 took to visiting the Hogwarts library. Hermione later reveals that he told her "...he'd been coming up to the library every day to try and talk to me, but he hadn't been able to pluck up the courage!" Krum had to rescue Hermione from the merpeople in the Great Lake for the Second Task. His relationship with Hermione, and taking her to the Yule Ball, provoked jealousy from Ron, who was, ironically, a fan of Krum's from his Quidditch days. The ever-annoying journalist Rita Skeeter, looking for revenge on Hermione, fabricated a story for Witch Weekly, claiming she was toying with the affections of both Krum and Harry. Harry became sick of telling people that Hermione was not his girlfriend and, when questioned, he told Krum, "We're friends. She's not my girlfriend and she never has been. It's just that Skeeter woman making things up."
Krum briefly returns in Deathly Hallows, as a wedding guest of Bill Weasley and Fleur Delacour. He talks to a disguised Harry about the lack of available women before having a heated discussion with Xenophilius Lovegood. He recognises a symbol that Xenophilius wears around his neck as the mark of Grindelwald, which is engraved into a wall at his alma mater Durmstrang; the symbol is later discovered to actually be the mark of the Deathly Hallows. Krum does not seem to mind when Ron asks Hermione to dance at the wedding, and comments, to Harry's annoyance, on Ginny's attractiveness. Krum eventually finds love in his native Bulgaria.[7]
