Rose is introduced in the eponymous premiere episode of the 2005 series. There, she is saved from an Auton attack by the mysterious alien Time Lord known as the Doctor (Christopher Eccleston), and assists him in preventing an invasion of Earth. Subsequently, the Doctor invites Rose to be his travelling companion, taking her to the end of the world and giving her a "superphone" so she can remain in contact with her mother Jackie (Camille Coduri), and boyfriend Mickey (Noel Clarke). In their travels through time and space, Rose learns the importance of not tampering with history, when she attempts to save the life of her father Pete Tyler (Shaun Dingwall), who had died when she was a baby. Throughout these journeys, she and the Doctor are haunted by two mysterious recurring words: 'Bad Wolf'. Rose, the Doctor, and new companion Captain Jack (John Barrowman) come to understand the meaning of this phrase when they encounter an unstoppable army of evil alien Daleks on the space station Satellite 5. To return to the Doctor after he sends her home to Earth in series finale "The Parting of the Ways", Rose tears open the console of the Doctor's time machine, the TARDIS, and becomes suffused with the power of the time vortex. Returning, she uses her power over the infinity of time and space to spread the words "Bad Wolf" over its entirety, then saving the universe from the Dalek invasion. Rose resurrects Jack, who died from Dalek fire, and destroys the Dalek fleet before the Doctor drains the energy out of her—by kissing her—to save her life from its harmful effects. Rose is horrified as the Doctor appears to die and regenerates into a new man (David Tennant), who proceeds to take the TARDIS and a terrified Rose to Earth, abandoning Jack on Satellite 5.
