Welcome to the freak show "American Horror Story" fans! During the FX show's panel at San Diego Comic-Con, creator Ryan Murphy revealed the Season 4 characters and announced that John Carroll Lynch will take over as the main villain.

It was previously revealed that Sarah Paulson would play a two-headed woman named Dot and Bette. On July 17 (before the Comic-Con panel) Murphy tweeted the first image of the conjoined twins. In the black and white picture, Paulson's character is seen sitting on a hospital wearing a hospital gown. The faces of Dot and Bette were not shown in the photo.

Joining Paulson will be Kathy Bates as Ethel Darling; Evan Peters as Jimmy Darling; Emma Roberts as Maggie; Angela Bassett as Desiree Dupree; Michael Chiklis as Wendell Dell Toledo, the ex-husband of Ethel and current husband of Desiree; and Jessica Lange as Elsa Mars, the head of the freak show.

The Season 4 cast also includes Frances Conroy, Wes Bentley and Finn Witrock. The plot for "American Horror Story: Freak Show" centers around a 1950s freak show (one of the last in the country) in Jupiter, Fla. Lange's character has previously been described as a German national who controls the freak show.

During an interview with TV Line last month, Murphy described Chiklis' character as a "strong man" who is also extremely vulnerable.

"He had scenes with Angela and Jessica Lange and [onscreen ex] Kathy Bates. I love the part because it's really written to be quite vulnerable, which is something I think Michael does so well- the strong man who's vulnerable," Murphy said. "I'm very excited to see [him] tussle with all those great ladies. And he's really up for it, really excited about it."

The new season of "American Horror Story: Freak Show" starts in October.
