"Starfire is an alien struggling to fit in and learn the ways of Earth while driving Robin insane with unrequited puppy love."[2]

Having been raised in an entirely different alien culture, Starfire has had trouble understanding Earth's ways. She has not even been able to fully comprehend English grammar or figures of speech yet; she does things like say the word "the" before most nouns. This causes her problems in episodes like "Knowledge". Starfire's constantly doing strange activities, and while the Titans try to set her on the correct course, they will occasionally take advantage of her naivety.
