Pteresa is snooty, arrogant, and cruel, believing that popularity and appearances are the most important things in life. She is also very greedy, willing to pretend to date Sheldon for money, and treating him with scorn all the while. She hates when people mispronounce her name.
- Pteresa's name is often mispronounced as "Puh-teresa", which is a running gag in every episode she appears in.
