Doctor Who: The Five Best Companion Introductions In NuWho

5. Rose Tyler

Where the original series premiere, 'An Unearthly Child', introduced the world of Doctor Who through companions Ian Chesterton and Barbara Wright, NuWho began its first episode, 'Rose', by following Rose Tyler, a teenage shop assistant destined to travel with The Doctor.

When the Mannequins in Rose's store come to life and attack, she is rescued by the mysterious Ninth Doctor. Rose takes it upon herself to investigate The Doctor, and soon, she becomes caught up in The Doctor's efforts to thwart an invasion by the Nestene consciousness, which controls the plastic robot Autons. Once she learns that The Doctor's ship, the Tardis, can travel through time as well as space, she accepts The Doctor's invitation to travel with him, and the rest is history.

Rose became the first companion seen by a brand new generation of Whovians, and remains a firm fan favourite to this day. Had Rose's character flopped, NuWho may very likely have died off before it even got started.
