At first she has somewhat of a snobby personality as she was seen calling Brain an amateur after beating him in a game of chess on numerous occasions. She also taps her fingernails, which drives her opponents crazy and is possibly the reason why she is a chess master. After Brain defeated her in another game of chess she gains respect for Brain.
