―Paulina after learning Danny is Danny Phantom
Paulina Sanchez is a character in Danny Phantom. She is a fifteen-year-old girl who has a crush on Danny Phantom, while brushing off Danny Fenton, without realizing they are one and the same. Knowing Fenton's affections for her, Paulina takes advantage of this, inviting him to parties because the "Ghost Boy" always makes an appearance where she is at.
Paulina is considered to be one of the most beautiful and popular girls at Casper High School, and is a shallow and self-absorbed teenager. However, she does love her father, as she went searching for him and facing Youngblood and showing concern for Star when she mysteriously vanished from camp.
