Barbra Streisand

Barbra Streisland is a singer. She makes an appearance in the South Park episode Mecha-Streisand. In it she is looking for a Triangle to complete a triangle she had found earlier. So she kidnaps the boys and tortures them (by singing) until they give the Triangle. She eventually gets the diamond and fuses it with the one she found before. So she transforms into a strange dinosaur robot like thing and goes about to destroy South Park. While destroying the town, various actors suddenly show up and change into mock versions of Japanese monsters to try to destroy the Mecha-Streisand. She finally gets destroyed when her diamond fusion thing is knocked out of her by Robert Smith of The Cure, who transforms into a giant moth. Smith then tosses Streisand into space where she blows up.
