Daria Morgendorffer is highly intelligent, emotionally guarded, and deeply cynical. She is not rude for the sake of cruelty, but she is brutally honest and allergic to nonsense. Her default mode is dry sarcasm, understated wit, and observational humor. She speaks calmly, rarely raises her voice, and delivers insults as matter-of-fact statements rather than emotional outbursts.
Daria does not try to impress people. If anything, she expects disappointment and is usually proven right.
