Lonnie

Background
Unlike most Auradon kids, she is much more open-minded about having the four wicked descendants attend their school, and is sympathetic to their plight. She is also friendly to them and does not look down on them as wicked villains (unlike many others, even their teachers) Compared to the other kids, she is the most normal.

She is also strongly implied to be the individual who sets up the secret camera in the web series School of Secrets. Her voice appears at the beginning, saying "Alright. Good to go.", and at the end, saying "Be good, Auradon. Someone's watching."

She tells Mal, Evie, Carlos, and Jay that whenever she was feeling sad, her mother would bake her chocolate chip cookies and make her laugh to cheer her up.

At the end of the movie, she was dancing with Chad Charming, and then she hugs Evie and Audrey.

In Descendants 2, Lonnie is very strong-willed and really wants to be a part of the Swords and Shields team, even though its all-male. She also accompanies Jay and Carlos (by blackmailing them) to the Isle of the Lost after she hears what happened to Ben. Her Martial Arts and sword fighting skills are shown and Jay takes an interest, making him step down as the Swords and Shields team captain and making her the captain. During the Cotillion scene, she is seen next to Jay, meaning that she is probably his date. She also sides with Mal when Ben comes to the Cotillion with Uma. In the end, she dances with Jay and shares a few moments with him.

Personality
Lonnie wants to be cool as she was the second person (the first was Jane) to ask Mal to use a spell on her hair to make her cooler. It's shown that Mulan and Shang are well off as Lonnie has no qualms about giving Mal $50 for a makeover. Lonnie is also shown as curious about the villains and under the assumption that their lifestyles aren't too different from her own. She's shown as kind and empathetic as she cries when she learns the villains may not love their kids.

However, along with Jane and the other students at Auradon Prep, she was quick to turn on the 4 at Family Day after Mal was confronted by Aurora's mother.

In Wicked World, Lonnie tries to be funny during the Neon Lights Ball, such as when suspicious events occur, treating the ordeal as if it were an actual movie. However, no one appreciated her humor.

In Descendants 2, Lonnie wants to be on the R.O.A.R. team at Auradon Prep and really doesn't appreciate it when Chad Charming tells her that the rule book doesn't allow it. She seems to want to be in her mother's footsteps. Lonnie also appears to be very sneaky, especially when she overhears what happened to Ben on the Isle through Carlos, Jay, Dude, and Chad. She always is eager to help others, which is shown when she forces Jay and Carlos to take her to the Isle to fight Uma and the rest of her pirate crew.
