When Yugi and Joey are invited to the Duelist Island by Pegasus, they will meet many legendary duelists. We will then find the two best players of Duel Monsters that are Rex Raptor and Insector Haga. In spite of their rank, we will observe that Rex Raptor will not lose once against an unknown, but twice against her. And this unknown person, then, will present herself under the name of Mai Valentine or Mai Kujaku in the original version.This duelist admits that she only plays to win money, which she hopes to get at the end of the duelist island tournament organized by Pegasus. She is ready to do anything to win her duels. Even cheating.Joey, when he confronts her for the first time, will highlight her cheating strategy. Mai Valentine used a different aroma on each of her cards to distinguish them in advance and plan her strategy accordingly. This, in turn, made her Harpy Ladies deck more powerful than ever.After losing to Joey, Mai Valentine, who initially presented herself as an antagonist, would end up helping Yugi and his gang on their journey. It is her who, by confronting Téa, will give hope to Yugi after this one lost against Seto Kaiba.Becoming later closer to Joey, she will participate in the events of Battle City to reaffirm her rank of duellist of foreground. She made it to the quarterfinals where she faced Marik. Although she narrowly missed defeating him, Mai Valentine was punished and imprisoned in an hourglass because of her opponent's powers, only to be rescued by Yugi. Mai Valentine is one of the most prominent secondary characters in the Yu-Gi-Oh! universe, even risking her life to fight for causes that do not concern her. Despite her superficial facade, the character is certainly not as interested in money as she claims. Thanks to Joey, Mai Valentine will indeed have changed for the better, seeking to thank him by any means necessary during the events of Duel Monsters.The Mai Valentine Funko POP figure, unsurprisingly, features her in a position to lead another Duel Monsters game. With her determined look and frowning eyes, the Mai Valentine figure shows the fiery determination of this major character in the Yu-Gi-Oh! Dressed very short, the Mai Valentine Funko POP figure here wears the uniform she used to wear during the Duel Monsters Island tournaments.With a long, full head of blonde hair, the Mai Valentine POP figure represents the character to the letter. Of course, the Mai Valentine Funko POP figure would not be complete without a dueling disc. We can see her grabbing a card that we can assume is a Lady Harpy. Her posture is similar to that of all Yu-Gi-Oh! characters, ready to play a game of Duel Monsters to show off her victory.
