Uh, Peter, you, uh... (starts scratching cheek) You got some... Some, uh... Right there...

The Doctor

Production code: 6E

The one where Colin Baker shows up early.

Written by Johnny Byrne. This four-episode serial first aired from January 3—12, 1983.

Travelling alone together (with none of that, thank you), the Doctor and Nyssa are interrupted in their travels by a random alien force that tries to take over the body of the Doctor. The Doctor is perturbed, sure, but the Time Lords are completely freaked out by this. Worried that it might happen again, which would be bad news as the alien is made of anti-matter, the Time Lords decide to drag the Doctor back to Gallifrey and kill him... and blame him for Romana leaving, which was no fault of his - she's just as stubborn as he is. With a token show of regret, Lord President Borusa gets Colin Baker to shoot the Doctor and haul him off to the Disintegration Chamber. But someone has conveniently rigged the circuit so that he ends up just being shoved into the Matrix (no, not that one) where the anti-matter alien torments the Doctor... and eventually turns out to be the long-lost (and allegedly dead) Time Lord Omega.

Meanwhile, in Amsterdam, a pair of English teenagers are menaced by a humanoid chicken with a label-gun. ...stop laughing! One of them is brainwashed, and he happens to be Tegan's favourite cousin, and Tegan happens to have lost her job, and happens to be visiting her cousin on this exact day. Then they all happen to be abducted by Omega, who wasn't actually aware that Tegan knows the Doctor at all.

Omega sends the Doctor back to Gallifrey and starts making a copy of the Doctor's body for himself. So the Doctor, Nyssa and the TARDIS run down to Amsterdam, to try and stop him, but they're too late. Omega sheds his massive helmet to reveal... the Doctor! In a most surreal scene, the Doctor and Omega-in-the-Doctor's-body banter back and forth before the Doctor reveals the big problem with Omega's plan: the body is only temporary.

Omega then leads the Doctor on a merry chase throughout Amsterdam, though he does take time out of his busy schedule to watch a Dutch street organ and test out his Villainous Creepy Smile on a little kid. The Doctor and Nyssa try to track him down, Peter Davison tries to speak Dutch and gets three out of three words wrong, and they freak out a lot of people around the Amsterdam grachten. Alas, Omega's antimatter body is dissolving, shown to truly gross effect by its face and hands dissolving into paste and green Rice Krispies. Eventually, Omega degrades to the point that he's a completely different actor, and the Doctor calmly (if reluctantly) takes out that label-gun and shoots Omega. Omega then fades to dust, and everything is back to normal.

...oh, and Tegan joins them again. The Doctor tries to put on a happy face, but it looks like he'd rather have Adric back.

This serial is notable in three ways. The first is that this features the return of Omega, who last appeared in the 10th anniversary special just over a decade prior. The second is that this serial kicks off the 20th anniversary season of Doctor Who, which commemorated the Milestone Celebration by consisting entirely of sequel episodes. The final? Sixth Doctor Colin Baker shows up for the first time — not as the Doctor, but as Jerkass security chief Maxil, the only Doctor until Peter Capaldi to appear in the series before landing the big role. In fact, there's even a scene of Maxil shooting the Doctor, something that's caused a lot of jokes within the fanbase and cast. Colin Baker himself joked that he'd gotten the part of the Doctor by shooting the incumbent.


  • Anti-Villain: Omega, when he has the Doctor's body... just goes around enjoying having a body again and smiling at people. Okay the smile is creepy, but the guy's only company for the past million years have been monsters made of red bubble wrap in an anti-matter dimension... he's a bit out of practice with social interaction.
  • Beware the Nice Ones: Nyssa shoots an awful lot of people in this story, and even pulls a gun on the Lord President Borusa.
  • Big Bad: Omega.
  • Bitch in Sheep's Clothing: Hedin, one of the story's Time Lords, who seems like a nice, genial sort of guy, and about the only one on the council fully in the Doctor's corner. He's the one helping Omega.
  • Body Horror: The slow degeneration of Omega's new body.
  • Boyish Short Hair: Tegan's new hairstyle.note 
  • Combat Pragmatist: Maxil.
    The Doctor: Hello, I'm the Doctor.
    Maxil: [shoots him with a laser gun]
  • Continuity Nod:
  • Contrived Coincidence: Tegan being in the plot at all.
  • Creator Cameo: John Nathan-Turner, wearing a sheepskin jacket, appears on-screen from behind the telephone box in part four. He would later claim this was a deliberate example of a Hitchcockian cameo, in reality he was trying to persuade passers-by not to get into shot.
  • Does This Remind You of Anything?: The Doctor gets zapped by Maxil and his goons on the grounds of "resisting arrest".
  • Extra Eyes: The Ergon appears to have four eyes on its face.
  • Forgot About His Powers: Once again Time Lords have forgotten they have the ability to regenerate and save themselves from dying permanently. Extra odd when regeneration is actually mentioned by some of the characters.
  • Friendly Target: Omega takes control of Tegan's cousin Colin and forces him to work (making him look pretty sick at the end of the story). When he realizes Tegan is a former companion to the Doctor, he threatens to kill her to make sure the Doctor cooperates (she was able to give him Omega's location though).
  • Ham-to-Ham Combat: Omega and the Doctor lob large roasts back and forth with glee as they devour everything in sight (not even Amsterdam is spared), even while Peter Davison plays off himself. Colin Baker does his absolute best to join in the fun.
  • It's All About Me: Maxil is positively bored with the Doctor, and spends much of his screentime looking mildly offended or checking his nails. Colin Baker played Commander Maxil not as a guest role, but as someone who thinks he's starring in his own series. John Nathan-Turner actually asked Baker to tone it down, because the show was called Doctor Who and not Commander Maxil. Baker replied that no person would ever consider themselves a minor character in someone else's life, and so he played Maxil as someone convinced he was the main character of the story. Of course, Baker soon would become the main character of the show, making the whole thing quite Hilarious in Hindsightinvoked.
  • Just Following Orders: Maxil, who nonetheless is too okay with it.
  • Kick the Dog: Omega's diabolical scheme is to get a body that isn't made of anti-matter and then either take over the Time Lords or just... run around enjoying life. So we get the message he is the bad guy, he enslaves a holidaying teenager to work his machinery, and then holds Tegan hostage to ensure the Doctor's cooperation.
  • Mirror Match: A lovely scene where Peter Davison plays the Doctor and Omega — with the latter dubbed by Ian Collier, of course. This was so well done that many on the DVD commentary remarked that the voice fit Davison better than his own!
  • Plot Archaeology: The main villain is revealed to be Omega, who first appeared in "The Three Doctors", which aired ten years previously. This kick-started the twentieth season, which featured a returning element from the series' past.
  • The Reveal:
    • Colin's cousin is Tegan.
    • The anti-matter creature is Omega.
  • Reverse the Polarity: Nyssa claims it's the way to turn matter into antimatter.
  • Scenery Porn: About a third of this adventure is in Amsterdam. Literally, this was the reason for the script being written. The script is able to Hand Wave it away, luckily, but it still feels damned strange.
  • Sealed Evil in a Can: Omega, still stuck in the anti-matter world we saw him in during the events of "The Three Doctors", serves as the main antagonist of the story.
  • Sequel Episode: To "The Three Doctors".
  • Shout-Out: The scene of Omega at the Punch and Judy show and interacting with a child was inspired by Frankenstein (1931) and Bride of Frankenstein.
  • Shown Their Work: Everything about Amsterdam checks out: the scenery, the street organ, the clothes. The background music is indeed a very popular Dutch tune about Amsterdam. The Dutch people are played by Dutch actors using their regular Dutch accents. And although the city is actually two metres above sea level, its cellars are indeed a bit below. The only thing that's off is Peter Davison's truly atrocious pronunciation of Dutch, but luckily, he only gets three words ("Jeugdhotel", "Centraal" and "Frankendael"). Although the city's layout is all over the place, with Frankendael somewhere in the grachtengordel, and the chase in Episode 4 teleporting between various parts of the centre.
  • Taking the Bullet: Hedin dies leaping in the way of a staser bolt Castellan had aimed at Borusa.
  • Unusually Uninteresting Sight: Averted. Watch when Peter Davison in monster makeup is staggering through Amsterdam in part 4: most of the citizenry barely notice, but there's a pair of people in one shot who outright goggle at the bizarre sight. Davison, on the DVD commentary, speculates that they weren't extras, and that it must have made for a weird holiday experience.
  • Villainous Friendship: Omega appears to be sincerely saddened and angered by Hedin's death.
  • Well-Intentioned Extremist: Hedin assists Omega in his plot apparently out of the sincere belief that Omega taking over Time Lord society would be better for it.
  • Woobie, Destroyer of Worlds: Poor, screwed up, crazy Omega.... His confusion when running around in Amsterdam, while wearing the Doctor's body, is actually sort of cute.
  • The X of Y
