During the first challenge, each contestant picks a representation of the dragon they will face from a bag. Fleur pulls out a Welsh Green, Viktor pulls out a Chinese Fireball, Cedric pulls out a Swedish Short-Snout and Harry pulls out a Hungarian Horntail. They are then tasked with collecting the dragon egg guarded by the dragons. On the day of the Yule Ball, Viktor goes with Hermione Granger. During the next challenge, each challenger must collect a loved one from the Black Lake. Viktor uses magic to transform his upper half into that of a shark and rescues Hermione, scaring the Merpeople in the process.
The final challenge begins and the challengers enter a maze. Fleur is attacked by Viktor and exits the challenge. Viktor attacks Cedric, but is stunned by him and Harry stops Cedric and tells him, Viktor has been bewitched. After the competition, Viktor leaves with the other Durmstrang students.
