[post_page_title]Ali Larter as Niki Sanders and Tracy Strauss[/post_page_title]
Ali Larter plays two of three triplet sisters through the series. At the beginning, she plays Niki Sanders, a single mother with dissociative identity disorder and superhuman strength. Later, the writers reportedly wrote Niki out so that Larter could play a different character, Tracy Strauss, and tell her origin story. Tracy doesn’t know anything about her sister or superhuman abilities, but discovers that she has the power to freeze anything she touches when she accidentally kills a reporter.
