Paulina is a student, cheerleader and bully at Casper High School.
Paulina is a tan-skinned Latina teenager. She has long dark brown curls with a pink hairclip on her side, with teal blue eyes and speaks with a Mexican accent.
She wears a pink crop-top, light blue denim capri pants and white flats.
Paulina is considered to be one of the most beautiful and popular girls at Casper High School.
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 their invitation.
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".
The two first interacted in "Parental Bonding" where Danny tried to ask Paulina to the dance which only had him ending up getting humiliated after his pants became intangible. In addition Paulina also likes Danny Phantom more than Danny Fenton.
In "Parental Bonding", After Danny gets humiliated after failing to ask Paulina out, Sam calls Paulina "shallow", which causes Paulina to try to get revenge on her by taking Danny away from her, but then later learns that Sam is not Danny's girlfriend.
Paulina is first seen in "Parental Bonding," with all of the boys fawning over her. Danny Phantom plans to ask her out to the school dance. After she makes fun of him Sam Manson comes over and insults her.
Planning to get revenge on Sam and thinking that she has a crush on Danny, Paulina accepts Danny's offer, who gives her an amulet. Danny finds out later that the amulet is enchanted, and attempts to take it back from her during the dance, using the excuse that it belongs to Sam.
While Danny's overshadowing his father, Sam goes into the bathroom with Paulina, saying that she only sees Danny as a friend and would like the amulet back. Paulina gives it back, revealing her cruel reason for going to the dance with Danny and announcing her plan to dump him.
This angers Sam enough to make the amulet turn her into a dragon, scaring Paulina enough to cause her to faint. As the dance finishes up, Dash Baxter is seen flirting with Paulina, but Sam lets go of her issues with Paulina for the time being.
She begins to have a crush on Danny's secret identity after this experience, decorating the inside of her locker with pictures of Phantom. At the water park in "Lucky in Love," Kitty overshadows her and began dating Danny after pretending to find out his secret.
After he discovers what's going on, Danny saves her again, much to her increasing gratitude.
In "Reality Trip," Paulina and the rest of the world find out the connection between Danny Fenton and Danny Phantom. She, along with the rest of the popular kids, helps him and his friends escape from the Guys in White and kisses him, putting Sam into a jealous rage.
Since Paulina is only a normal human girl, she has absolutely no powers at all. However, she has shown several ghost powers, which is usually because of another ghost that is possessing her or something similar, the powers she showed are:
- Ghost Sense (briefly): shown in "Doctor's Disorders", when bitten by a ghost mosquito. It seemed to cause her some kind of physical pain (mild at best), but after Danny Phantom explained what it was and how it worked, she seemed not to mind anymore. After she and the other students were cured of the mosquito virus, she lost this ability.
- Dragon Transformation (briefly): in the episode "Parental Bonding", while having the amulet of the princess Dorathea, she had the same powers that the princes has. When she gets angry she becomes a dragon having these powers Flight, Fire Breath, Superhuman Strength, and Superhuman Endurance.
- Flight (briefly): when she was possessed by one of Walker's men, she was able to fly at great speed, either because she is a dragon or a ghost (maybe even both) she is able to fly at great speed.
- Back Sliding (briefly): when she was possessed by one of Walker's men she was able to zip on the surfaces. (This is how Danny's learned how to zip on the surfaces).
- Superhuman Strength (briefly): when she was possessed by one of Walker's men she was nearly strong as Danny. While as a dragon possibly due to her size, she is strong enough to overcome Danny.
- Superhuman Durability/Resistance (briefly): when she was possessed by one of Walker's men she was able to crash against a signboard without any sign of injury. Also when she was a dragon she was able to survive to several attacks from Danny without any further damage, even able to get up after being knocked out by Danny without any problem.
