Max doesn't highly of her and often calls her dumb. Zoe is frequently suspicious of her brother's travels, but Max puts her to sleep so she can't reveal their secret. Zoe is also usually grounded at the end of her brother's travels, especially by her strict dad, for her impish and mischevious behavior.
Zoe has red hair and wears a blue bow in it. She also wears a red dress with a white shirt underneath.
