"And Volkov and Vulchanov had better get back on those brooms. . . yes. . . there they go. . ."
-- Ludo Bagman's commentary during the 1994 Quidditch World Cup (GF8)
Volkov was a Quidditch player who was a Beater on the Bulgarian National Team at the 1994 Quidditch World Cup.
Along with fellow Bulgarian Beater Vulchanov, Volkov was on the Bulgarian side that lost the 1994 Quidditch World Cup final against Ireland. His other teammates were Viktor Krum as Seeker, Dimitrov, Ivanova and Levski (Chasers), and Zograf the Keeper (GF8). The events of the tournament were overshadowed by the chaos following the appearance of the Dark Mark (GF9, Pm).
Aggressive and legendary beating skills
Volkov derives from the Russian word volk meaning "wolf" (Behind the Name).
