Slist Fayflut Marteveerthon Slitheen was a female Raxacoricofallapatorian from the Slitheen family. She was the star of the holovid show Doctor Who?, and had her own chat show called The Slist Show.


While on Gharusa Prime, Slist pretended to be the Ninth Doctor. As "the Doctor", she was the star of Doctor Who? and author of "autobiography" Doctor's Orders. "The Doctor" was voted Cosmopolitan's sexiest planetary saviour for nine years in a row. His companion both in the show and on Gharusa Prime was another Slitheen who assumed a human name of Penny.

She captured Rose Tyler when Rose found out that she was an imposter and took her to Clix as "the Doctor"'s companion instead of Penny. (COMIC: Doctormania)

She later forcibly brought the Doctor onto her show, The Slist Show, as a guest for The Slist Show Christmas Special. Under advice from her make-up artist, a Chapadio, she also brought General Yolaktorin of the Retjarvik-Sattavarian. She gave the order to shut off the lights to save Yolaktorin from melting in his make-up, when the Doctor told her to. (PROSE: Christmas Special)
