*Leeloominaï Lekatariba-Lamina-Tchaï Ekbat de Sebat (aka "Leeloo") is one of the Supreme Beings of the Universe. She was sent to Earth in corporeal form to become the Fifth Element, the final piece of a powerful weapon needed to destroy Evil.

Leeloo's human form after being recreated by the laboratory is that of a Caucasian female in her late teens, early twenties. Nineteen to be exact, although that is only on the surface. She is described by Korben as being "a really big fare that he couldn't resist", being 5'9", having long legs, blue eyes, and great skin. She has bright orange hair that is blonde at the roots and falls just past her jawline. She is fair-skinned, tall, slender, and physically perfect, as mentioned by David when she strips nude in front of him and Cornelius.

Soon after her laboratory "birth", Leeloo is clothed by the scientists in wide, white thermal bandages that conceal her nudity somewhat. After meeting up with Cornelius, David provides her with clothes and an electronic box similar to a camera that applies cosmetics to the eyes. The clothes she wears include combat boots, flesh-colored leggings with a fishnet pattern, a white crop top, and an orange monokini. While investigating the cosmetic unit, she activates it and applies eye makeup, seemingly pleased with the results.

It is unknown what Leeloo looked like before the accident with the Mondoshawans. She is blunt and straightforward in words and actions. Leeloo is also shown to be quite emotional; she is horrified by the violence she sees while viewing clips and pictures of human wars and sheds tears of shock and sadness. Also, during the diva's operatic performance, she has flashbacks of the night she and and the Mondoshawans were attacked, shedding tears but then quickly becoming angry and swiftly defeating the Mangalores she encountered. Furthermore, she becomes depressed and unwilling to complete her mission, plaintively asking, "What's the use of saving life when you see what you do to it?" referring to the death and violence humans seemed so willing to inflict on others. However, she seemed happy and overwhelmed with emotion when Korben confessed his love for her. Overall, she is shown to be kind to her companions.

Leeloo is a Supreme Being of the universe. It is implied that there is more than one. Being genetically superior to humans and virtually flawless, Leeloo is a perfect specimen of human health and fitness.*
