In the ninth season of the BBC America's TV series "Doctor Who," Maisie Williams has finally been featured in episode 5, which was called "The Girl Who Died," last Saturday.

However, the International Business Times revealed that her character will be "very different from her first," being the sweet and innocent character Ashildre.

The site further disclosed that the "Game of Thrones" star will be showing off two different personas - as Me and as Highwayman - while she drops her real name.

The International Business Times shared that when Maisie Williams is wearing her corset in "Doctor Who," she will be known as Me, but when her eyes are covered with a mask and her hands are holding a gun, she becomes the Highwayman.

Being the Highwayman, the 18-year-old English actress and dancer will be identified as well as the Knightmare, a criminal who "catches the Doctor's attention after she gets her hands on some alien technology."

Meanwhile, the site speculated that Leandro (Ariyon Bakare), the man with a lion face, is an alien who could be the Highwayman's target.

In the sixth episode of "Doctor Who," which will be entitled "The Woman Who Lived," Maisie Williams' character will meet Doctor Who (Peter Capaldi) and Clara (Jenna Coleman) after a century.

"After living so many lifetimes, Ashildre/Me/the Highwayman is very different from the Viking girl the Doctor revived," the report dished.

In the meantime, the BBC Radio 1 Teen Award for Best British Actor in 2013 recipient stated in an interview with BBC (as shared by Metro UK) that the upcoming episode this weekend will surely be exciting as changes seemed inevitable.

"She has witnessed so much and lost so much and been through so much trauma that it has really changed her as a person," she said. "It's a wonderful episode and I'm so thrilled to have played both sides of her character."

Catch Maisie Williams on "Doctor Who" every Saturday at 9:00 p.m. EDT on BBC America.
