Worst Doctor Who Episodes

The Rani, needing the Doctor's expertise, shoots down his TARDIS, crash-landing it on planet Lykertya where the Doctor dies and subsequently regenerates. She biochemically induces selective amnesia before disguising herself as Mel in order to angle him deceptively into repairing one of her broken machines. The real Mel? Left behind in the TARDIS, alive but unconscious, where she's found by a grim rebel Lakertyan who then makes off with her.

The Rani's deviousness inadvertently sets the Doctor and Mel against each other - she having yet seen the Doctor in his new regeneration, he believing Mel is the Rani disguised, and each thinking the other is an agent of utmost evil to be brought down. Two unanswered questions linger: Why has the Rani collected geniuses, and why is she messing around with "strange matter."

The solstice nears, making it time for the Rani to bring her plans into fruition. The Doctor's sympathies for Beyus, ruler of the Lykertyans, are rather qualified. Beyus' heart is for his people yet something prompts him to collaborate fully in helping the Rani reach all her objectives. The answer, he's told, lies within the Center of Leisure.

The Rani, at last, links the Doctor into her great brain machine, the crowning jewel in her component packet of geniuses brought together to turn Lakertya itself into one vast cerebral mass capable of redirecting time anywhere in the universe, giving her absolute power over all creation.

Elton Pope is an ordinary man intrigued by the world of the Doctor. When he and fellow enthusiasts - L.I.N.D.A. - meet the mysterious Victor Kennedy, their lives will never be the same again.

When children vanish into thin air in 2012 London, the Doctor and Rose find the answers in a seemingly ordinary household and a girl whose drawings can come to life.

The Doctor struggles to adjust to his new self. Elsewhere a set of genius twins are kidnapped, whose mathematical computations can manipulate features of the universe. They're immediately put to work by aliens for an as yet unknown end.

The Doctor takes Peri to Titan 3, a desolate hunk of rock in space where he hopes to find some solitude for awhile. Instead he finds the lone but unconscious survivor of a recent spaceship crash in sight of a mound-shaped complex where no formalized structure should exist.

The Doctor arrives on Jaconda, once lush and green, to find it completely devastated by giant gastropods. Old legends about the planet's half-human/half-slugs weren't just myths after all. With or without help from the Doctor and his unpredictable mood swings, Lt. Lang is up for rescuing the twins, who are finally informed of the grand purpose they've been brought to Jaconda to accomplish.

The Doctor and Edgeworth deduce that the real plan of Mestor, the gastropod ruler of Jaconda, will not only destroy Jaconda but lead to the devastation of other planets. Together they hope to thwart him despite his formidable ability at slipping into people's minds and controlling them.

The Doctor takes Amy to the future inside Starship UK, which contains in addition to British explorers, an intimidating race known as the Smilers.

Following the death of Adric, the Doctor arranges a trip to Victorian London to lift everyone's spirits but the Tardis instead materializes at Heathrow Airport where a British Airways Concord has mysteriously vanished.

The Doctor's TARDIS is stolen, and tracking it down reveals the existence of an alien named Kalid controlling events in the past. While the Doctor challenges Kalid's motives for being there, Tegan and Nyssa discover the source of Kalid's power - an even greater threat for the Doctor.

The Master commandeers the Doctor's TARDIS, leaving the stranded Time Lord time to work out the mystery of the alien sanctum he's been trying to enter. Inside lies an immense power - the entire Xeraphin race, thought long lost but distilled into a single living essence, ready for rebirth but now suffering a dual gestalt personality, good versus bad, thanks to the Master's meddling with it. As the two Xeraphin halves enter into a struggle for dominance of the whole, the Doctor works for a favorable outcome before the Master can succeed at turning them into his new power source.

Incorporating the Xeraphin race into his TARDIS power system, the Master has won, but technical obstacles and a bit of sabotage from friendlies give the Doctor a bargaining chip for the lives of the hijacked and enslaved airline passengers and crews - with maybe, just maybe, some hope for the Xeraphin race as well.

The court looks into the Doctor's investigation of Thoros Beta, home planet of the Mentors whom the Doctor suspects of selling advanced weaponry to primitive cultures.

Having been put through a makeshift truth extractor, the Doctor appears damaged, apt to mimic the personalities of those with whom he has eye contact. He eventually abandons Peri and a gung-ho warrior king in favor of joining in with Sil and Dr. Crozier in the latest of their perverse projects.

While the Doctor helps Dr. Crozier transfer Lord Kiv's brain into a new host skull, Peri accompanies King Yrcanos as he searches for the Alpha Resistance fighters whom he feels, most certainly, will follow him into glorious battle against the Mentors and the Doctor.

The first transfer is flawed, so Dr. Crozier needs to transfer Lord Kiv into another host body. Unfortunately, Peri meets all the requirements for the subsequent candidate. Since the Doctor's been helpful and has somewhat of a personal interest in Peri, he's permitted to locate an equally suitable substitute candidate, if he can. The prosecution rests.
