The titular character on the BBC hit TV series Doctor Who is the last of the Time Lords, a race capable of time travel and regeneration. The Doctor has regenerated its body 13 times, and for the first time it its history it regenerates as a woman (Jodie Whittaker) for its 13th life. She travels the space-time continuum with her companions Graham, Yasmin and Ryan. This guide covers the 13th Doctor’s first iconic – and eccentric – look of suspenders, cropped pants, rainbow shirt and coat.

Amy Pond’s beau and eventual husband, Rory Williams wasn’t initially invited to hopscotch around the universe with the Doctor. But once he got a taste of it, nothing could stop him from joining Amy: not a wedding, not death and not an unfortunate two-thousand-year stint as a Roman centurion.

Rose started out as a normal nineteen-year-old shopgirl until the Doctor blew up her shop (there were Autons inside at the time – don’t ask). But given the choice between an ordinary life and adventure through all of time and space, Rose chose the latter. Hey, who wouldn’t?

Peter Capaldi is the 12th incarnation of Doctor Who, accompanied by companion Bill. In the 10th series of Doctor Who, his costume has changed from a navy coat with red lining to a black coat with blue lining.

After regenerating, the 10th Doctor traded in the 9th Doctor’s leathers for a pinstriped suit and a pair of Chucks. Although more gregarious than his previous incarnation, this Doctor still let the universe know if you threatened his friends, there was a reason his enemies called him the Oncoming Storm.

The Fourth Doctor (Tom Baker) is the most tenured and iconic Doctor Who, lasting seven seasons before his transformation. He’s instantly recognizable by his curly brown hair, eyes that constantly boggle, and of course his impractically long multi-colored scarf.
