The name Dragan is of Balkan and Eastern European origin and is derived from the slavic element 'dorgu', which means 'precious'.
Some time before the events of Yu-Gi-Oh 5D's, Dragan went exploring with his father and found "Thor, Lord of the Aesir" in a cave with tree roots under a church. But once he grabbed the card, the cave started to collapse and his father was injured. When leaving the hospital, he is encountered by Lazar who offers him a chance to duelJack Atlas for the title of Duel King, where he would receive money for his father's injuries.
However, he would only receive the money if he lost on purpose and made it look like Jack defeated him easily so he could uphold his name as the king. Dragan almost used a card that would likely have won him the Duel, but nevertheless accepted defeat so that his father could receive treatment.
Some time later, Dragan is caught in an avalanche while mountain climbing. Fortunately, he is saved by his Rune Eye. After this, he is approached by Halldor who encourages him to use "Thor, Lord of the Aesir" and join him. Dragan accepted and, together with Broder, they formed Team Ragnarok.
World Racing Grand Prix
Dragan, along with his companions, were on a plane flying towards New Domino City for the WRGP. At the same time, the Three Pure Nobles achieved Falsification of history. Dragan, along with the others, noticed that their Aesirs had protected them from the wave. Dragan also noticed another "phenomenon" which others had not noticed.
Later, Dragan and his team appeared publicly to host an exhibition duel against the other teams in the WRGP. He chose to duel Jack Atlas. During the duel, after summoning "Thor" and attacking "Red Dragon Archfiend", the two monsters emit a strange wave of energy while battling. Because the force began to destroy the building, the duel was called off.
After his team meets up with 5D's, Dragan reveals the truth to Jack about their duel from three years ago. He also states that their score will be settled when they duel on the semifinals, to which Jack agrees.
Finally, the day of the WRGP semifinals begin, and Dragan faces Jack in a long-awaited rematch. Strangely, they both get the same hand as that of their first duel, therefore repeating the same moves. However, this time Dragan strategically calls forth Thor and pushes Jack to a corner by reducing his life points dramatically.
Still, his Aesir proves no match when Jack summons "Red Nova Dragon". Although Dragan tries to counter the dragon's "Burning Soul" attack, Jack succeeds in making it strong enough to destroy Thor and defeat Dragan.
In episode 147, he and his teamates have survived. They were last seen cheering on Yusei during his duel against Z-ONE
Dragan is one of three Duelists who plays a "Nordic" Deck. Specifically, he plays a "Nordic Beast" Deck, which is based on iconic mammalian animals from Norse mythology, buffered with Trap support. His ace card is "Thor, Lord of the Aesir".
