Kersti is a sticker fairy who appears in Paper Mario: Sticker Star. She is Mario's primary partner throughout the game, and grants him the ability to use the Battle Spin and paperization. Kersti's name is an anagram of the word "sticker" but with the letter C removed. She also appears in the 3DS version of Super Smash Bros. for Nintendo 3DS/Wii U as a trophy.


According to her introduction, Kersti came from the Sticker Star on the night of the Sticker Fest, as part of the process of granting everybody's wishes. Kersti first meets Mario at the site of the Sticker Fest, stuck to a sign after Bowser destroys the Sticker Comet and steals one of the Royal Stickers for himself. After Mario peels her off, Kersti goes off on him, believing it was he who destroyed the Sticker Comet, but after Mario offers to help search for the Royal Stickers, she forgives him, and they set off to find the six Royal Stickers.

At the end of their adventure, Kersti sacrifices herself in the final battle with Bowser, allowing Mario to use her as a sticker to increase his power and overcome the power granted to Bowser by the last Royal Sticker. However, after the battle, Mario brings Kersti back to life by wishing on the Royal Stickers. Having returned to the site of the rebuilt Sticker Fest, she gets angry at Bowser for trying to steal the Sticker Comet again. She then jokes about changing her career, and Mario, Peach, and Bowser laugh.

General information


Kersti is a friendly and generous sticker, often claiming to be a delicate and refined lady. However, her feisty side tends to stand against this claim, and she's easily angered and tends to make hasty judgments.

Powers and abilities

Kersti has the ability to "paperize" stickers by pressing the Y button, turning the stickers into objects that can be placed into designated locations. She also has the ability to create a tool used during any battle she is present in called the Battle Spinner; this is a slots-type minigame where Mario must match up two or more images in order to use more stickers per turn, and if Mario gets three of the same image, a special effect will occur.

Like Goombario, Goombella, and Tippi before her, she can perform tattles (by pressing the L button). However, she usually only provides insight on what the player should do next (and sometimes descriptions of places), as she cannot tattle enemies. Due to the nature of the tattle, only one particular one is usually available at any one time during the game, and changes as the player continues through the game. Thus, in certain scenarios when Mario is separated from Kersti, he can't use these abilities. The player also cannot save the game or return to the World Map while separated from Kersti. In the final battle with Bowser, Kersti sticks herself into Mario's album, and when used by Mario, creates a special battle spinner that always wins by landing on her image, restores 20 of his HP and allows him to use 5 stickers every turn for the rest of the battle. Mario also becomes shiny, allowing him to do normal damage to Bowser despite his Royal Sticker.

Name NTSC-U Description PAL Description
Paper Kersti A sticker fairy who went to the Mushroom Kingdom on the Sticker Comet, she is very strong willed. Though she appears paper thin, her heart runs deep, and she shows herself to be a loyal companion on Mario's quest to help the Mushroom Kingdom by recovering the Royal Stickers. Kersti came from the Sticker Star to help grant everyone's wishes. Mario got the sharp end of her tongue to begin with, but she quickly proves herself to be an indispensable ally on their quest to find the Royal Stickers. She may be made of paper, but she clearly has a heart of gold.


  • In both areas where Mario loses Kersti, you are unable to save the game or return to the world map. This is most likely so you cannot go to other places without Kersti.
  • Kersti slightly resembles Rosalina's crown as both are silver and have turquoise gems on both sides
  • Kersti's personality is nearly identical to that of Starlow.
  • With powerful stickers, it is possible to defeat Bowser entirely without ever using Kersti. She will remain in the album after the battle and can be tossed like any other sticker.
    • Through hacking, it is possible to use her outside the final battle; she will activate a regular battle spin after her lines of dialogue when used, and she sells for 15 Coins.[1]
