Paulina Sanchez (Danny Phantom.)

Paulina is a vain, stylish, insensitive and Danny Phantom-obsessed girl who usually thinks she is above anyone below her social status, described as "shallow" by Sam Manson.

Paulina only cares about fashion, popularity and beauty, and she is willing to use others for her own benefit, like going to the dance with Danny Fenton in order to make Sam jealous in "Parental Bonding."

Paulina also only gives Danny and his friends invitations to her quinceañera because Danny Phantom usually appears when they're around, even asking Phantom to take an invitation so that she can cancel theirs.

There are moments where she can be very cold and serious, such as treating Valerie negatively after she and her father become poor. Whenever angry, Paulina seems to have no issues taking revenge, trying to attack Danny for choosing Sam in the beauty pageant in "Beauty Marked" and chasing after Tucker because she has faint memories of him making her wash his feet in "King Tuck."

Contrary to her regular behavior, Paulina is able to be nice and friendly on occasion. She's genuinely thankful to Danny Phantom for saving her and likes him beyond just his good looks and popularity, but also his heroism and kindness. When her "satellite" friend Star disappears in "Claw of the Wild," Paulina is very worried about her, especially if Star gets sunburned.

Depending on the situation, she is willing to help, shown when she helps disguise Tucker as an adult and fights Youngblood's Crew to save her parents in "Pirate Radio".

Even after finding out that Danny Phantom is actually Danny Fenton, she still accepts him while helping him and his friends get away from the Guys in White.
