Barbra Streisand

Barbra Streisland is a singer and actress, famous for songs such as "People" and "Papa, Can You Hear Me?", and films such as Funny Girl and Yentl. She appears as a primary character in the episode Mecha-Streisand

Appearances
In "Mecha-Streisand", Cartman discovered a strange triangle-like object while on a school field trip. Deciding it was worthless, he tossed it aside only for Kyle to claim ownership of it, at which point it was discovered that the Triangle was in truth a a rare archeological find. News of the discover goes public, drawing the attention of the musical diva, Barbara Streisand, who realizes it to be the second half to the "the Diamond of Pantheos."

It is revealed that Streisand's "mother was a Jackal, and her father was an insurance salesman" and that she is an "evil, egotistical diabolical bitch" who wants to conquer the world with the relic. The diamond was split into two separate triangles and hidden at different points of the Earth, but Streisand found one of the pieces during the shooting of My Fair Lady. The other piece happens to be the triangle Cartman found, and according to Maltin if Streisand were to get her hands on that triangle she would become the most evil and dangerous creature to ever walk the Earth—Mecha-Streisand.

Streisand rushes to South Park and makes several attempt to get the Triangle from Kyle and later Cartman (who regained ownership of the Triangle). In the end she resorts to singing, which horrifies the boys, and causes Cartman to give up his prized possession rather than listen to her tortuous voice much longer. Joining the triangles together, she transforms into Mecha-Streisand and destroy South Park. She is however defeated by Leonard Maltin, Sidney Poitier, and Robert Smith, all of whom take the forms of Japanese movie monsters.

Although she doesn't appear in person again, Streisand remained a constant character of fear and loathing in South Park. In the episode, "Spookyfish", Comedy Central ran an ad campaign during the time leading up to the broadcast of the Halloween episode, stating that it would air in "Spooky Vision" - something so terrifying that it couldn't even be described. As the episode was introduced, it was revealed that this horror was in fact a photo of Barbra Streisand repeated in the four corners of the television frame. Streisand's face was also used for scene transitions in the episode. Each act of the episode featured a different photo.

In the episode, "Osama Bin Laden Has Farty Pants", Eric Cartman holds up a series of signs to show that Osama bin Laden is crazy, including "Screw Ball", "Jackass", and an image of Barbra Streisand.

Streisand appears again as "Mecha-Streisand" in the South Park 200th Episode, but with a completely new CG appearance.

Trivia
After her appearance in Mecha-Streisand, Streisand publicly came out against South Park. She attacked it not for her portrayal as a monster, but for promoting cynicism among children, despite the fact that the show isn't intended for children.

As Mecha-Streisand, she resembles the Mechagodzilla from the Japanese Godzilla franchise. Her appearance in Mecha-Streisand resembles the original Mechagodzilla while in 200, she resembles the newer Millenium Mechagodzilla.
