Penny is a very professional, helpful and hardworking person who is also kind, thoughtful and supportive. She helps to solve problems, usually disagreements between two sides, by looking over everything carefully and trying to find a middle point or compromise that satisfies everyone. She gives encouragement to Marinette Dupain-Cheng, finds amusement in a misunderstanding that André Bourgeois has relating to her, and she puts on a good face with dealing with business partners, acquaintances, and teenagers. While usually nice, Penny takes on a serious, curt, or confrontational demeanor depending on the situation, like when she sternly demands to Vincent Aza that he stops bothering and taking photos of Jagged Stone in "Pixelator".
- Penny's last name and Jagged's last name are a reference to the rock band The Rolling Stones.
- In "Pixelator", André Bourgeois confuses her name with Jagged Stone's pet crocodile, which causes Penny to be genuinely amused by his mix-up.
- Troublemaker appears another time in "Gamer 2.0" for Gamer's powers.
