Vivian Wong is the Asian Duel Monsters champion. In the English dub, it was stated that before that, she was a successful model, actress, and Kung Fu champion. She participates in Kaiba'sKC Grand Championship. She is very whiny, hoping to get what she wants by obscure means. She is an avid fan of both Yugi and Kaiba to the point of obsession, especially Yugi, whom she hopes to turn him into her "love slave", much to Tea's ire.
She used her beautiful tactics and attacks to completely defeat her opponents. During the Asian Duel Monsters tournament, she defeated the supreme Clan of Nine Dragons and later gained "The Duel Queen of Asia" title.
To that point, she have a fierce rivalry with Rebecca Hawkins for Yugi's affections and had even gone so far as to blackmail Yugi into Dueling her outside the contest, threatening to leave Yugi's grandpa with an injured back if he didn't accept. If she won, then Yugi would have to go on a date with her (become her "love slave" in the Japanese version); however, she lost all her Duels.
In the Japanese Epilogue (Not shown in the English version), Vivian is seen with Mai Kujaku Dueling against the Meikyū Brothers on the Great Wall of China. Since Mai was not participating in the Grand Championship, only briefly seen near the end, Vivian seemed to fill in her role as the "femme fatale" of that arc.
