I am Starfire (real name Princess Koriand'r), or "Star" for short, is one of the main characters of the Teen Titans series. She is an alien princess from the distant world of Tamaran, and one of the five founding members of the Teen Titans. She is also Robin's main love interest and finally becomes his girlfriend in the series finale movie. Starfire was born and raised on the planet Tamaran before arriving on Earth and joining the Teen Titans. The Tamaraneans are an emotional race that see feelings and sensations as the force that drives their very livelihood and strengthens their abilities. In fact, it is their emotions that further increase their natural abilities of flight, and projection of pure ultraviolet energy. Because of this, Starfire is inherently the most sensitive member of the Titans. Starfire is said to be an incredibly pretty, lovely and beautiful girl. She is tall with bright orange skin, large green eyes with light-green scleras, and small rounded eyebrows. She has straight, shiny, waist-length, fiery-red hair with short bangs.

Her uniform consists of a sleeveless violet crop top, a violet miniskirt, a silver belt, and thigh-high violet boots with silver soles and bands at the top. For armor, she wears a silver gorget with a round green gem embedded into it, silver bracers with green gems over the backs of her hands, and a silver armband on her upper right arm.

As a Tamaranean, she has alien physiology, which includes a long violet tongue and nine stomachs (possibly for storing food during meager times). She also seems to resemble some Japanese girls, inheriting similar eyebrows and very shiny hair.
