Luvbi

Luvbi is a Pure Heart-turned-Nimbi, and a character from Super Paper Mario.

She is believed to be the daughter of Queen Jaydes and King Grambi, and she runs away a lot to escape her overprotective parents. She does not know why her parents are so protective, but it is later revealed that she is really a Pure Heart, and Jaydes and Grambi made the Pure Heart into a living form to protect it. They admit that over time, they loved Luvbi and felt as if she was their real daughter. Luvbi speaks in a strange, pseudo-Old English, and constantly is putting down others (namely Mario, Princess Peach, Luigi, and Tippi).

Even though she changes into the Pure Heart at the end of Chapter 7, and the Pure Hearts disappear at the end of the game, Luvbi appears next to her mother and father after the game. She said even she does not know how she exists as a Nimbi again.

Trivia

 * Though somewhat obvious, Luvbi is the only "named" Pure Heart; all others are only conjecturally named by color.
 * When in Pure Heart form, Luvbi is white--this is similar to how there was a white Crystal Star in Paper Mario: The Thousand-Year Door.
 * Luvbi's name derives from love and Nimbi.
