Plavalaguna

Blue, sort of squid-looking alien opera diva who sings a trance-y take on Donizetti's "Il dolce suono" in the 1997 sci-fi film The Fifth Element. Her performance ends in probably the worst possible way a performance can end: with the performer shot and Bruce Willis pulling goopy stones out of her body. She was played by Maïwenn Le Besco, but Inva Mula-Tchako provided her singing voice.
