Vivian

How Vivian joined the Tourney
Vivian's first appearance in the game is during the interlude following Chapter 1, during which she and her two sisters are sent by Sir Grodus to ambush Mario in the Boggly Woods. When Mario arrives there, however, he learns that the picture they were to use to identify him was misplaced by Beldam, who is quick to blame Vivian for the loss. Mario is forced to battle the sisters when he comes to claim Flurrie's Necklace, which Vivian had found in the woods. Upon her defeat, she departs with Marylin and Beldam, leaving the necklace behind. After Mario's name and body are stolen by Doopliss, Vivian appears in Twilight Town alongside her sisters, who plan to defeat Mario using a Superbombomb. When the weapon turns up missing, however, Vivian is once again blamed and left to search for it. When Mario finds the bomb and returns it to her, it turns out to be broken, but she thanks him nonetheless for his help and, after learning of the theft of his identity, resolves to return the favor by helping him, unaware that he is truly Mario. Using her powers, Mario eventually learns Doopliss's real name, and the duo corners him at the top of Creepy Steeple. Upon learning Mario's identity, Vivian is reluctant to assist in the ensuing battle, though she returns to his side after three turns, having decided that he treats her better than her sisters and is more deserving of her help. Following Doopliss's defeat, Mario stands up for Vivian when she is questioned by his other partners; she ultimately thanks him by handing him the Crystal Star and thus joins the team. At the very end of Mario's adventure, Beldam and Marilyn end their villainous activities and promise not to mistreat Vivian again. When Mario is preparing to leave Rogueport, Vivian is about to tell Mario that she has a crush on him, but decides otherwise, saying that she thinks he and Princess Peach will make a good couple.
