Svetlana Petranova (Kelly Sheridan) is the secondary antagonist in Barbie in Rock 'N Royals. Svetlana was the Russian head of Camp Arabesque. She was one of the three judges at the sing-off between Camp Royalty and Camp Pop, along with Allegra James and Prince Reginald.
When Camp Pop and Camp Royalty decided to have a sing-off, Svetlana was chosen to be one of the judges. The other two judges were Prince Reginald, who would remain loyal to Camp Royalty, and Allegra, a musician who would likely side with Camp Pop.
Clive, assistant to the headmistress of Camp Royalty, Lady Anne, bribed Svetlana with a necklace so she would to vote in favor of Camp Royalty. The other two judges were Prince Reginald of Thistlebrook, who would remain loyal to Camp Royalty, and Allegra James, a musician who would likely side with Camp Pop.
Svetlana wore the new necklace at the sing-off, where Camp Royalty and Camp Pop were expected to perform separately. Camp Royalty and Camp Pop chose to perform as one group, so Allegra and Prince Reginald abstained from voting because of the situation change.
Svetlana voted for Camp Royalty, which made them the winners until Lady Anne and Finn Oxford, head of Camp Pop, overruled the vote after realising that rock and royalty can mix. Clive admitted that he bribed a judge, and so Svetlana quickly left and drove away before she could be caught.
Svetlana has light skin, light hair, brown eyes and pink lips. She wears a black boat neck top, black tights, pink tutu and pink shoes. She also has a headband on that is black with white flowers, and small earrings. She originally had on a necklace that had two ballet slippers on it, but it was replaced by a more decorative one with flowers.
