Sonia has long orange hair and green eyes. She is flirty, funny and witty. She is quite popular and extroverted, owing largely to her looks and charisma. She is also intelligent, curious and passionate about her research, and has built up a reputation as a prodigy. She is talkative, and somewhat dirty-minded: that hardly retracts from the fact that she is, above all, a good person, and does not care about glory, fame, power or money, but about understanding Pokemon.
