Viktor Krum (Bulgarian: Виктор Крум; born April-August, 1976) was a Bulgarian wizard. He attended the Durmstrang Institute, and was also the Seeker for the Bulgarian National Quidditch team at the age of eighteen while still at school.
In 1994, he played in the final of the Quidditch World Cup. The Irish won the match, but Viktor caught the Golden Snitch to end the match on his terms. Later in the year, he was part of the Durmstrang delegation sent to Hogwarts School of Witchcraft and Wizardry for the Triwizard Tournament. He was selected by the Goblet of Fire as the Durmstrang Champion, and competed bravely. However, the Tournament ended in tragedy with the death of Cedric Diggory, and Viktor returned home. In 1997, he attended the wedding of Fleur Delacour and Bill Weasley.
He retired from Quidditch after the Bulgarian defeat in the final of the 2002 World Cup, but came out of retirement to compete in the 2014 World Cup, out of a desire "to win the World Cup before I die". The Bulgarian side famously won the World Cup that year, after beating Brazil.

Some idiots copied it onto their books and clothes thinking to shock, make themselves impressive — until those of us who had lost family members to Grindelvald taught them better."
- —Viktor on the wizard who murdered his grandfather[src]
Viktor was born to Krum and his wife between May and August 1976. He grew up in Bulgaria, and attended the Durmstrang Institute. He was one of the last people to purchase a wand from Gregorovitch Zauberstäbe before Mykew Gregorovitch's retirement.
During his time at the school, Viktor was confronted by what he believed to be the symbol of Gellert Grindelwald, which was indeed the symbol of the Deathly Hallows, that had been carved into the walls by the wizard himself. Other students at the school began copying the symbol onto their books and clothing as a way of trying to shock and impress. Highly insulted, since his grandfather had been murdered by Grindelwald, Viktor and several other students who had also lost family at the hands of the Dark Wizard taught them the error of their ways.
