Princess Rose is a representative selected by Sartorius to Duel Jaden in his place. A fan of the classic fairy tale "The Frog Prince", she claims to have the ability to see Duel Monster spirits (manifested as three "princes" named Jeffrey, Roosevelt and Percival in the English dub), but others do not believe her. Jaden, however, notices the spirit of a frog prince watching over her after their duel.
In the original version, Rose is very sophisticated and polite, speaking like a true princess. In the English dub, Rose speaks with a stereotypical Valley Girl accent, using terms such as "diva", "whateve", and "not!".
Rose plays a "Frog" Deck. Through the effects of her trump card "Des Frog", as well as "T.A.D.P.O.L.E.", Rose is able to Summon three copies of the former relatively quickly. With her assault team in play, she is able to neutralize all threats and constantly strengthen her monsters with various other cards.
