Vivian (Paper Mario)

Vivian is the fifth party member in Paper Mario: The Thousand-Year Door. At the beginning of the game, she was a member of the Shadow Sirens and Secret Society of X-Nauts, but she eventually switched sides, due to the fact that she was constantly being belittled and verbally abused by her older sister, Beldam. Outside of battle, Vivian can use the Veil technique to sink into the shadows with Mario to avoid enemies and obstacles. In battle, Vivian's default ability, in addition to Veil, is Shade Fist, where she can punch enemies and set them on fire. After she's leveled up, Vivian gains the abilities, Fiery Jinx and Infatuate. Fiery Jinx allows her to burn all enemies on screen, while her Infatuate ability confuses enemies, causing them to attack one another, instead of Mario and his party.
