Ms. Purdy is Dan Kuso's old school teacher. She is shown to be very strict, as she assigned Dan after school detention for the rest of that semester (though Dan was never seen going to detention). She appeared only in episode 2. She punished Dan, because she thought Dan was playing with a toy at school, while Dan was actually talking to Drago. She seems to think that Bakugan are just toys for kids, due to Drago being silent when she took him.
- Her eyes were never shown since she was wearing glasses.
- Even though she appears to look young, she sounds like an elderly lady.
