5 of 43 BBC America, ITV Plc
Best known to Whovians as: Rory Williams, aka Mr. Pond, aka the Lone Centurion. Initially seen only as Amy's milquetoast nurse fiance, he became another companion to the Doctor and eventually tested his own mettle and proved his steadfast loyalty to his woman.
Where he is now: Darvill appeared as the Duke of Buckingham in Starz's The White Queen and the Rev. Paul Coates in BBC America's murder mystery series Broadchurch.
Fun fact: Although fans welcomed Rory's opportunities to show off his action heroism, this often resulted in his (temporary or fake) death, which thereby backfired and was compared to the commonplace mortality of South Park's Kenny. Nevertheless, Rory's off-screen but real death in "The Angels Take Manhattan" was still poignant for fans.
6 of 43 BBC America, Jack Rowand/The CW
Best known to Whovians as: River Song, aka Melody Pond, the cheeky time traveller who is journeying through an opposite timeline as the Doctor (his first meeting with her is her last, and vice versa). Their great love and attraction for each other was made even more tragic by the fact that she gave up her regenerative powers to save his life.
Where she is now: She's appeared as Dinah Drake Lance (but apparently not Black Canary) on The CW's Arrow.
Fun fact: Executive producer Steven Moffat was loosely inspired by Audrey Niffenegger's novel The Time-Traveler's Wife when conceiving of the romance between the Doctor and River.

She appears in the Doctor Who 50th anniversary special along with Tennant and will play Brona Croft in the Showtime supernatural thriller Penny Dreadful alongside Josh Hartnett, Timothy Dalton and Eva Green.

She also starred in the BBC One sitcom Big School.
Fun fact: Executive producer Russell T. Davies originally intended Donna to be a one-off character, not an ongoing companion, because he thought her abrasive personality would annoy viewers.

Where he is now: After Doctor Who, Morrissey appeared in The Other Boleyn Girl and the PBS miniseries The Hollow Crown. He currently portrays the despotic, eyepatch-wearing Governor on AMC's The Walking Dead.

Where she is now: The former Jekyll and Merlin actress is also known for starring in the failed Bionic Woman reboot and has guest-starred on USA's Covert Affairs as Auggie's former lover, Helen Hanson.

The biggest difference, however, was that Lady Christina had an elite background and had her own life that made her not as susceptible to the Doctor's influence.
16 of 43 BBC, Marvel

18 of 43 BBC, Cate Cameron/The CW
Best known to Whovians as: Jack Harkness, a former Time Agent and con man from the 51st century who traveled with the Ninth Doctor and Rose before sacrificing his life.

Where he is now: After Who and Torchwood, Barrowman appeared on Desperate Housewives as eco-terrorist Patrick Logan, guest-starred on Scandal as a fixer and currently plays Malcom Merlyn on The CW's Arrow.
Fun fact: Harkness is bisexual, the first Doctor Who character to ever be openly anything but heterosexual. But since he is from the 51st century, two human genders aren't the only options, so Harkness prefers the term "omnisexual" instead.
19 of 43 BBC
Best known to Whovians as: The Eighth Doctor, who only appeared on television once in the 1996 TV movie that was supposed to act as a backdoor pilot to a Fox series that failed to earn a pick-up. McGann embodied him as alternately playful and dark.

20 of 43 BBC

21 of 43 BBC; Warner Bros/MGM

23 of 43 BBC

Pinafore, The Woman in White) as well as on screen, appearing on Casualty, Jonathan Creek, Top Gear and Doctors. He finished in eighth place in 2012's UK version of I'm a Celebrity... Get Me Out of Here!
Fun fact: Although Baker's tenure as the Doctor was unpopular — from the 18-month hiatus to refresh and his high-profile firing — he never held a grudge and continued to celebrate his time on the show. His many performances reprising Six in the audio plays have earned him respect from fans who have voted him one of the "greatest" Doctors in the format.
25 of 43 BBC; BBC

He was incredibly compassionate, especially to his young companions, and sometimes made decisions by flipping a coin.

Where he is now: Davison has quite a hefty resume following Who that includes starring in Mystery!: Campion, At Home with the Braithwaites, The Last Detective,, Law & Order: UK and the comedy Pat & Cabbage.
Fun fact: Davison claims that the cricket-inspired clothing was his idea because the producers wanted wardrobe that conveyed both action and eccentricity in the Fifth Doctor.
26 of 43 BBC; Big Finish
Best known to Whovians as: Perpugilliam "Peri" Brown is an American college student majoring in botany who became the companion to the Fifth and Sixth Doctors. She was seen as one of the more controversial companions because it was argued she was only added to the series to wear form-fitting/revealing clothes.
Where she is now: Besides recording various Doctor Who audio plays, she's also had a robust career on stage, appearing in Killing Jessica, Taboo and Tom Stoppard's Rock 'n' Roll.
Fun fact: Peri wasn't the most convincing American. Not only did her accent wander among various U.S. dialects, but Bryant commented that often producers insisted the character use a British term (such as "lift" instead of the American counterpart "elevator") in order to not confuse the viewers.
27 of 43 BBC; Big Finish

Fun fact: Stickson felt he was often in "bondage" because the producers often didn't know what to do with Turlough and as a result often had the Doctor's enemies capture him.
28 of 43 BBC; New Line Cinema

30 of 43 BBC; Sidgwick & Jackson Ltd; St Martins Pr
Best known to Whovians as: The second incarnation of Romana, one of the Fourth Doctor's companions who is a Time Lady from Gallifrey.
Where she is now: After Who, she took to the stage for a few years, but eventually retired officially from acting. Naturally, that hasn't stopped her from reprising the role of Romana in audio plays, the 1993 charity special Dimensions in Time or the 2003 webcast of Doctor Who: Shada.
Fun fact: She was briefly married to her co-star Tom Baker for 16 months before they split.

31 of 43 BBC; Big Finish
Best known to Whovians as: Adric, a mathematically gifted young native of the planet Alzarius and companion to the Fourth and Fifth Doctors. He's the youngest male companion throughout the series.
Where he is now: Since his character died in the series, most of his follow-ups in the Who universe have been as either ghosts, figments of the Doctor's imagination or other creative incarnations of the dead Adric. Other works include a range of Shakespearean plays, the one-man show Adventures of Huckleberry Finn, and more recently a guest-starring role in the Dark Shadows audio drama.
Fun fact: Because Adric was rather young, snotty and overconfident about his math skills, he has the distinction of being one of the most "hated" companions ever.
32 of 43 BBC
Best known to Whovians as: Nyssa, a young aristocrat from the planet Traken, whose father's body was taken over by the Master. She exhibited a latent psychic ability. She's very giving and left the Doctor to help start a hospital on a space station.

Fun fact: Sutton claims that Nyssa takes off her skirt and remains in her slip for half of her final adventure with the Doctor to please fans, who have often complained that Nyssa is too covered up. In the script, it is explained that the companion was feeling ill and wanted to loosen pressure on her stomach, but that was never made clear on screen.

She also held a position with Women in Film and Television UK and currently works as the project coordinator for the charity Project MotorHouse, for which she's organized two Doctor Who conventions to raise funds.
Fun fact: Producer John Nathan-Turner claims he was considering two names — Tegan, after a friend's niece in Australia, or Jovanka, the name of Yugoslavian President Josip Broz Tito's widow — for the new companion and wrote both on a piece of paper. A script editor thought Jovanka to be the last name, and thus Tegan Jovanka was born.

In 2009, she won acclaim for her one-woman show Me and Jezebel and continues to perform on stage in plays such as Death by Fatal Murder and the Inspector Pratt trilogy.
Fun fact: Jo is seen as one of the Doctor's "sauciest" and sexiest companions, despite (or perhaps because of) her daffy personality. Her departure is still seen as one of the most emotional in the series.

When Hines recovered, Jamie's real face was restored.
37 of 43 BBC America/Big Finish Productions

Where she is now: After Who, Watling (who was a child star back in the day) went on to the World War II series Danger UXB and has reprised her role as Victoria in the Doctor Who audio drama Three's a Crowd.
