Kersti

“As their caretaker, it's my duty to find all of them, or else I can't return to the Sticker Star!”

—Kersti, Paper Mario: Sticker Star

Template:Character-infobox Kersti is a sticker fairy who appears in Paper Mario: Sticker Star. She is Mario's initial companion in the game. Kersti's name is an anagram of the word "sticker" but with the letter C removed. Kersti has the ability to "paperize" stickers by pressing , turning the stickers into objects that can be placed into designated locations.

In the end, she sacrifices herself when she lets Mario use her as a sticker during the final battle with Bowser, in order to overcome the power granted to him by the last Royal Sticker. However, after the battle, Mario brings her back to life by wishing on the Royal Stickers. Shortly after, she scolds Bowser for trying to steal the Sticker Comet again. She jokes she might want to change her career, and Mario, Peach, and Bowser laugh.

Kersti is shown to be benevolent, but also has a feisty side to her. She has an aggressive dislike of Kamek.

She also slightly resembles a Pixl from Super Paper Mario.

Abilities

Kersti grants Mario the ability to use the Battle Spinner and Paperize. He can also turn to her while in a level (by pressing ) and hear her hints and observations on the area, similar to the Tattle ability in other games. Thus in certain scenarios when Mario is separated from Kersti, he can't use these abilities. In the final battle with Bowser, Kersti transforms herself into a sticker, and when used by Mario, creates a special battle spinner that always wins by landing on her image. Then for the rest of the battle, Mario can use 5 stickers in one turn, and the shielding power of Bowser's Royal Sticker is nullified.
