Lonnie is a character in the movie Descendants, played by Dianne Doan. She is the daughter of Fa Mulan and Li Shang who enjoys martial arts and hip-hop dancing.
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. 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, Mulan would bake her chocolate chip cookies and make her laugh to cheer her up.
She is the second girl Mal gives a magical makeover to, having paid $50, which Evie needed for clothing material.
She is a main suspect of being the mystery girl from School of Secrets.
