Vivian

"I'm with Mario all the way! Today, Sis...I'm going to punish YOU, you hear me?"

- Vivian

Vivian is a major character in Paper Mario: The Thousand-Year Door. Vivian originally worked as a member of the villainous Shadow Sirens alongside her sisters, Beldam and Marilyn. Later, Vivian defects from the Shadow Sirens and joins Mario as his fifth party member. She is consistently put down by her oldest sister, Beldam, and has had a poor relationship with both her sisters for quite some time when Mario meets her. Although she suffers from an inferiority complex throughout the events of the game, Vivian's character develops as she learns to respect herself.

Paper Mario: The Thousand-Year Door
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 gives him a kiss to thank him 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.

Super Paper Mario
In Super Paper Mario, Vivian appears as a Catch Card won by winning the Duel of 100 in the Sammer's Kingdom. Francis also has a Vivian plush doll and there is a painting of her in Mario's house. Like Mario's other past partners, there is unused sprite data for Vivian, suggesting that they were originally going to appear in Super Paper Mario, but were removed during development.

Super Smash Bros. Brawl
In Super Smash Bros. Brawl, Vivian appears as a Sticker. Her sticker is a small sized one and increases the attack power of energy related attacks by 5. Her sticker can be used by any character.

Gender
There is debate about her gender, as Beldam insults her by calling her a man in the Japanese version. The tattle log also says she is the "youngest sister er... brother." Though due to the use of "she" and "her" after the insult it is possibly intended to be a joke that Mario took the insult seriously.

Powers and abilities
Outside of battle, Vivian possesses the same ability Lady Bow has in Paper Mario, but Vivian's works in a more interesting effect, as instead of literally turning invisible, Vivian can pull Mario into their shadow, where they can hide and nothing can get them. This allows them to get past objects that move over them, and avoid sight from enemies and their attacks. Vivian possesses the strongest magic of any partner in the game.

Attacks and stats
At Initial Rank (-), Vivian has 15 HP. At Super Rank (*), Vivian has 20 HP. At Ultra Rank (**), Vivian has 30 HP. Vivian is one of the most versatile characters in the game.

Catch Card

 * Card Type: Rare
 * Card Description: It's Vivian from the last Paper Mario adventure. She was a great friend once she split from her sisters.
 * How to Obtain the Card: The Duel of 100 in Sammer's Kingdom needs to be completed in order to obtain all Paper Mario: The Thousand-Year Door partner cards from King Sammer.

Trivia

 * During the battle with Vivian, she can use Fiery Jinx when her HP is low, but when Vivian joins Mario's party, she has to be Super Ranked to learn that ability.
 * Vivian is the second of four characters in the Paper Mario series (with Lakilester being the first, Bowser being the third, and Luigi/Mr. L being the fourth) to battle Mario and join his party.
 * For this reason, Vivian is the only party member in Mario's Tattle Log.
 * If the player looks through Professor Frankly's trash can after fighting the Shadow Sirens, Vivian's Tattle could be found while Marilyn's and Beldam's could not. This foreshadows that Vivian would join the party and not be rebattled with the other sirens later, as only Tattles of one-time enemies could be found in the trash.
 * If the player performs Veil's stylish command after all of the enemies are defeated, no star power is awarded.
