Starfire is very cheerful and sweet, yet somewhat naive and considerably insecure, but her naivety should not be mistaken for stupidity. An alien and an outsider, she is still rather new to Earth and its customs. Presumably, because English is not her first language, Starfire speaks without contractions and misuses idioms. Additionally, she uses several Tamaranean words and phrases. She takes friendship very seriously and is easily distressed when others, especially her friends, argue or fight.
