"Doctor Who": One of These Things Doesn't Belong Quiz

Answer: Boom Town

The villain of "Boom Town" is Blon from the earlier episodes "Aliens of London" and "World War Three". Patrick Troughton portrays the Doctor and the villain Salamander in "The Enemy of the World". Not only does he play two characters, both of them impersonate the other at least once. In "Meglos", Meglos traps the Doctor in a time loop and takes his form, allowing Tom Baker to play the antagonist. Matt Smith gets to play a villain in "Nightmare in Silver" when the Doctor's mind is partly overtaken by Mr. Clever.

These three are not the only Doctor actors who play antagonists. Peter Davison briefly plays Omega in "Arc of Infinity". As well, William Hartnell portrays a villain in "The Massacre", a story in which the Doctor rarely appears.

Answer: The Web Planet

The TARDIS crew enter E-Space in "Full Circle" and remain there until they escape two serials later in "Warriors' Gate". The TARDIS herself nearly dies when entering a parallel world in "Rise of the Cybermen" but manages to recover after the Doctor gives her some of his regeneration energy, which is enough to let her escape the parallel universe in the next episode. The Doctor reaches a parallel Earth in "Inferno" while fiddling with the TARDIS console. He doesn't exist there, and all his UNIT friends are fascists.

The Doctor, Barbara, Ian, and Vicki visit Vortis in"The Web Planet". It is populated by human-sized insects. While it is a strange world, Vortis it not in a parallel world or alternate dimension.

Answer: The Happiness Patrol

Anyone who touches the Krynoid seed pod in "The Seeds of Doom" slowly turns into a Krynoid. Peri and Areta are turned into strange hybrids via cell mutator in "Vengeance on Varos". Thankfully, the Doctor destroys the machine before the transformation is complete, and the two return to normal.

In "Planet of the Ood", Ood Sigma gives Halpen a mixture that slowly turns him into an Ood. "The Happiness Patrol" features no human mutations, just a creature made of candy who likes using candy to kill political dissenters.

Answer: The Sixth (Colin Baker)

Six gets his the legal way--he visits the wardrobe room. Three, after waking up from his coma and showering, borrows a velvet suit and lace shirt from the hospital. He must like the look because he wears velvet suits in various hues until he regenerates. Eight, after wandering around a hospital wearing nothing but a sheet, takes his clothes from the locker of a man going to a fancy dress, or costume, party. Likewise, Eleven selects his outfit from a hospital locker.

Answer: The Impossible Planet/The Satan Pit

The TARDIS breaks apart when it leaves the known universe and spirals into the Land of Fiction in "The Mind Robber". All that's left is the console, which Zoe and Jamie cling to. It reassembles itself at the end when the Doctor and friends return to their time. When the TARDIS is destroyed in "Frontios", the pieces slowly start coming back together; the Doctor then tricks the Gravis into completely reassembling it. The Silence blow up the TARDIS in "The Pandorica Opens" and "The Big Bang", but the explosion is undone. The TARDIS falls down a deep hole in "The Impossible Planet" but is found unharmed in "The Satan Pit".

TARDIS abuse also comes in the form of shrinking. The TARDIS and some of the characters shrink in "Planet of Giants", "Carnival of Monsters", "Logopolis", and "Flatline".

Answer: Snakedance

In the first two episodes of "The Ark", the Doctor and friends find themselves on a spaceship that's taking a remnant of humanity to a new planet. After he creates a cure for a disease that he accidentally introduced, the Doctor leaves and returns to the ship years later. The Fourth Doctor lands on a jungle planet in "The Face of Evil" and discovers that he is Xoanon, the god of a warrior tribe, and also The Evil One. He realizes he visited the planet earlier and put his own personality into a computer, which went mad. The Ninth Doctor ends up on Satellite 5, the setting of "The Long Game", again in "Bad Wolf" and sees how the place changed when he left after defeating the Editor.

"Snakedance" is a sequel to "Kinda" in that the Mara demon from the earlier story remains in Tegan's mind, but the TARDIS crew visit Manussa this time, not Deva Loka.

Answer: The Curse of Peladon

The Doctor finds out in "The Ark in Space" that a few ships left Earth when the planet was in danger from solar flares; the humans were to return later to repopulate Earth. In "Frontios", the Doctor says that he shouldn't interfere with the colonists' survival on the title planet, but ends up helping them anyway. The TARDIS goes forward about 100 trillion years in "Utopia" to a time when the stars have all burned out. A small group of humans hope to reach Utopia, a place where they might survive the collapse of reality. In "The Curse of Peladon", the Doctor is mistaken for an Earth representative and has to help the king of another planet decide whether or not to join the Federation.

It's amazing how many times humanity fizzles down to a small number, but survives and thrives. It's also astounding how often we meet someone who's been manipulating human history--Scaroth in "City of Death", the Fendahleen in "Image of the Fendahl", the Silence throughout the Matt Smith years, and the Daemons in "The Daemons". It's remarkable that they don't all run into each other.

Answer: The Edge of Destruction

"The Deadly Assassin" is a Fourth Doctor serial in which the Doctor goes to Gallifrey, where he must find out who killed the President. He leaves Sarah Jane on Earth before returning to his home planet; she doesn't even appear in this serial. In "Midnight", the Tenth Doctor and Donna take a vacation to a diamond planet. She stays at the hotel by the pool while he goes on a bus trip that ends with him very nearly being killed off for good. The Twelfth Doctor is trapped in a castle in the middle of an ocean in "Heaven Sent". At one point, Clara appears in a vision.

"The Edge of Destruction" is a very early First Doctor serial where he, Susan, Barbara, and Ian are stuck in the TARDIS together. Bizarre things happen and paranoia sets in before they figure out the problem and solve it.

Answer: Leela

In "The War Games", the Time Lords return Jamie and Zoe to their own times to the moment just after they left with the Doctor. All of their memories of the Doctor, except for each one's first adventure, are erased. The Doctor erases all of Donna's memories of him in "Journey's End" so that her mind doesn't burn up. Leela never loses her memories of her adventures.

Answer: The Second (Patrick Troughton)

The Third and Tenth Doctors die of radiation poisoning in, respectively, "Planet of the Spiders" and "The End of Time". Three saves at least two planet's worth of people; Ten saves the grandfather of a recent companion. Five dies of spectrox toxaemia in "The Caves of Androzani"; symptoms include rash, painful cramps, bloody blisters, fever, paralysis, and finally death.

He eventually finds an antidote but gives it all to his new friend Peri to save her. Two doesn't die, per se--the Time Lords in "The War Games" force him to regenerate as part of his punishment for stealing the TARDIS and fleeing Gallifrey.
