Everyone's favourite time traveller returns to do battle with his greatest foes. Years after his peremptory departure from Totters Lane (see the first ever story, 'Doctor Who: An Unearthly Child'), the Doctor (Sylvester McCoy) returns to 1963 London to discover that the military have been called in to do battle with an alien invasion force at Coal Hill School. The aliens turn out to be none other than the Daleks, whose Emperor wants to obtain a Gallifreyan stellar manipulator - known as the Hand of Omega- which was left in the Doctor's care. However, a group of renegade Daleks are also after the Hand, in league with a fascistic human group. Can the Doctor defeat both Dalek armies and prevent the Hand of Omega being misused?

Two adventures from the early 1980s with Peter Davison starring as the Time Lord. In 'Kinda' (1982), the Doctor (Davison), Tegan (Janet Fielding), Adric (Matthew Waterhouse) and Nyssa (Sarah Sutton) land on paradisical Deva Loka, for rest and recuperation. However, the military expediton on the planet has lost several crew members, and the Doctor and Adric are taken hostage by the near hysterical Hindle. Meanwhile, Tegan's dreams have provided the gateway to an ancient evil, the snake-like Mara. The Doctor must prevent the Mara from taking over the Kinda and destroying the expedition, as the wheel of creation begins to turn. In 'Snakedance' (1983), a loose sequel to 'Kinda', Tegan must have made a mistake when she was setting the co-ordinates for the TARDIS, because the Doctor certainly hadn't intended landing on Manussa. When the Doctor learns that Manussa was once the home of the Sumaran Empire, he realises that an evil force has begun to take over Tegan's will. This force, the Mara, is planning to use Tegan as a vehicle to retake power on Manussa. Just as the celebrations to commemorate the destruction of the Sumaran Empire by the Federation are about to take place, the Legend of Mara is about to come true.

On the planet Tigella, the mysterious source of all power - the Dodecahedron - is failing. Zastor, the leader of the planet, decides to call on an old friend to help them. An old friend who travels the universe in a blue police box.

Another adventure for everyone's favourite Time Lord. When the TARDIS makes an unscheduled landing on a mysterious spacecraft heading towards planet Earth, the Doctor (Peter Davison) and his cohorts are surprised to find that the crew members are drawn from a variety of ancient Earth cultures. Their leader, however, is a frog-like alien known as Monarch (Stratford Johns), and the more the Doctor finds out about his plans for the future of Earth, the less he likes them.

Another adventure for everyone's favourite Time Lord. The Doctor (Colin Baker) and Peri arrive in the north of England during the Luddite uprisings, and discover that brilliant but amoral Time Lord the Rani is stealing the chemical which promotes sleep from the mine workers' brains. The Master is also in town, planning to use the disruptive Luddites to deprive the Doctor of his TARDIS and destroy him once and for all.

The Doctor (Sylvester McCoy) returns to Perivale in 1883 in an attempt to cure Ace's phobia about the place. He soon discovers that aliens, hiding beneath a Victorian house, are planning to take over and destroy the planet. It is now up to the timelord to defeat their plans and once again save the planet from a deadly fate.

Another adventure for everyone's favourite Time Lord. The TARDIS is low on Zyton 7, and the only planet with the ore available is Varos. Upon landing, the Doctor (Colin Baker) and Peri discover a society addicted to real life TV violence, ruled by a corrupt regime. They have to help the rebel Jondar and thwart the Thoros Betan delegate, Sil, in his attempts to obtain the Zyton for his own conglomerate.

Another adventure for the seventh incarnation of the philanthropic Time Lord. The Doctor (Sylvester McCoy) and Ace arrive on the planet Segonax, home of the Psychic Circus. Ruled over by the evil Chief Clown and his gang of robots, the Circus is designed to entertain a masked audience of three - and failure meets with instant death. Joined by the boastful Captain Cook and his companion, Mags, the Doctor and Ace enter the Circus talent contest - and find themselves having to compete with killer bus conductors and werewolves along the way!

Sylvester McCoy plays the Doctor and Bonnie Langford his assistant, Mel, as they journey to a hi-tech housing block. Once a paradise residence, now a run down and almost deserted nightmare city, a war has developed over the years of its downfall. The Doctor is soon on the case when sinister happenings begin to occur.

Two classic Doctor Who adventures, one from the 1970s and one from the 1980s, both featuring those sinister humanoids the Cybermen. In 'Revenge of the Cybermen' (1975), the Doctor (Tom Baker), Sarah Jane (Elisabeth Sladen) and Harry (Ian Marter) return to the space station Nerva (from 'The Ark in Space') to recover the TARDIS. They discover the crew decimated by a strange plague, to which Sarah falls prey. The Doctor realises that the plague is part of a plot by the Cybermen to destroy Voga, the planet of gold - gold being the only thing which is lethal to them. At the same time the Vogans are planning to destroy the Cybermen with their Skystriker rocket. The three-part adventure 'Silver Nemesis' (1988) was made to celebrate Dr Who's 25th anniversary. A statue, blasted into space 350 years ago, crashes into Earth in the core of a meteor. The Doctor (Baker) and his assistant Ace (Sophie Aldred) must fight two armies from different time periods, a regiment from 1988 and a battallion of soldiers from 2688, whilst guarding the statue from the clutches of the Cybermen.

The Doctor (Colin Baker) is suffering from some post-regenerative trauma, and, after trying to strangle companion Peri, takes off to a deserted asteroid to become a hermit. There he discovers a plot by the Gastropod Mestor to kidnap two mathematically brilliant twins and shift some planets around in order to release more of his slimy ilk. Obviously he has to be stopped, but is the Doctor up to it? Colin Baker's first outing as the Doctor.

Another adventure for the intrepid time traveller. While visiting a Galactic Tollport, the Doctor (Sylvester McCoy) and Mel (Bonnie Langford) win a trip to Disneyland in 1959. On board the spacebus they meet Chimeron queen Delta, whose people have been wiped out by mercenary Gavrok (Don Henderson) and his men. Knocked off course by a satellite, the bus in fact delivers its passengers to the Shangri-La holiday camp in Fifties Wales, but while the Doctor becomes determined to make the most of the break - and Delta embarks on a romance with Earth mechanic Billy - Gavrok is not far behind. Watch out for a guest appearance by Ken Dodd as the Tollmaster.

The longest 'Doctor Who' story ever. The Doctor (Colin Baker) is put on trial by his people the Time Lords for interference in the affairs of others; three segments of his past and future are presented as evidence. 'The Mysterious Planet' shows the Doctor and Peri (Nicola Bryant) in a battle with a megalomaniac machine on the planet Ravalox, but what are the mysterious 'secrets' it protects? 'Mindwarp' shows the Doctor apparently betraying Peri to the vile Sil (Nabil Shaban) and the Mentors - can the Matrix be falsifying the evidence against the Doctor? In his defence he presents 'Terror of the Vervoids', a future story where the Earth is threatened by evil plant life forms. In the final two episodes, 'The Ultimate Foe', the Doctor learns the truth about his prosecuting counsel, the Valeyard (Michael Jayston), and has to enter the Matrix to battle for his remaining lives. This was Colin Baker's last story as the Doctor.

All four classic Doctor Who stories featuring the alien species, the Sontarans, who first appeared in the 1973 story, 'The Time Warrior'. The Sontarans are a self -cloning race who live in a militaristic society in the 'southern spiral arm of the galaxy'. Humanoid in appearance, with a squat build and distinctive dome-shaped heads, they are far stronger than mere humans and possess an unquenchable thirst for war. The other stories in this set are 'The Invasion of Time' (1977), 'The Two Doctors' (1984) and 'The Sontaran Experiment' (1975).

Three feature-length Doctor Who adventures. In 'Doctor Who and the Silurians' (1970), Jon Pertwee stars as the third Doctor, who is called to an atomic research station in Derbyshire to investigate a series of mysterious events. His questions uncover a vicious ring of in-house saboteurs and something a bit more slimy. In 'The Sea Devils' (1972), after visiting their old enemy the Master (Roger Delgado) in his remote island prison, the Doctor (Pertwee) and Jo learn of several recent accidents at sea, all of which have been accompanied by reported sightings of strange monsters. The Doctor discovers that the creatures responsible are the Sea Devils, acquatic cousins of the Silurians who are out to reclaim the planet Earth from mankind. In 'Warriors of the Deep' (1983), The Doctor (Peter Davison), Tegan and Turlough arrive at an underwater base on an Earth in the future on the brink of Atomic War. Helping to trigger this war are the planet's original inhabitants, the Silurians and the Sea Devils, aided by their killer pantomime horse, the Myrka.

Sylvester McCoy stars as the renegade Time Lord in the last ever new story to air on television. It focuses on the Doctor and Ace in their battle against the Cheetah People who are abducting people from all over West London, and with the help of the Doctor's nemisis The Master, taking them to a distant planet.

The Fourth Doctor departs, the Fifth arrives and the Master returns in these three classic 1980s adventures!

Another adventure for everyone's favourite Time Lord. The Doctor (Tom Baker) and Romana take a holiday on the planet Argolis, in the giant pleasure dome known as the Leisure Hive. Unbeknown to them, Pangol, the son of the Argolin leader Mena, is planning to provoke a war with their age-old enemies the Foamasi, using the Tachyon Recreation Generator to create an army of duplicates of himself.

The Doctor (Sylvester McCoy) and Ace arrive in England towards the end of the Second World War. At a secret naval base, Dr Judson has built a machine capable of breaking German cyphers, but the machine is in fact used to translate ancient runes and summon up Fenric, an evil creature from the dawn of time. Includes material not shown on the original broadcast.

When the Doctor (Peter Davison) tries to take Tegan (Janet Fielding) back to Heathrow Airport, the Tardis arrives in the 17th century instead of the 20th century. The time-travellers discover that a space capsule has landed nearby and its alien occupants intend to wipe out life on Earth by releasing rats infected with a great plague.

Two episodes of the classic sci-fi series featuring the Fifth Doctor, Peter Davison, and the shape-changing android Kamelion. In 'The King's Demons' (1983), the renegade Time Lord forces Kamelion (Gerald Flood) to pose as King John in 13th century England. 'Planet of Fire' (1983) sees the Doctor (Davison) and Turlough (Mark Strickson) arriving in Lanzarote on Earth to investigate the transmission of an unusual signal that turns out to be emanating from a mysterious alien artefact.

All 12 episodes of the Black Guardian trilogy from the twentieth season of the long-running sci-fi series. On discovering public schoolboy Turlough lost aboard an apparently abandoned cruiser in space, the Doctor (Peter Davison) transports to Earth in 1983, only to meet up with his old friend friend and UNIT colleague, Brigadier Lethbridge-Stewart, who has apparently lost all memory of him. Back in 1977, Tegan and Nyssa meet the younger Brigadier and a disfigured alien they believe could be a regenerating Doctor. However, it turns out that this is all in fact part of a plot to destroy the Doctor by the Black Guardian, who has made a deal with Turlough to grant him transportation away from Earth if he kills the Doctor. Episodes are: 'Mawdryn Undead (Parts 1-4)', 'Terminus (Parts 1-4)' and 'Enlightenment (Parts 1-4)'.

An early adventure for the sixth incarnation of everyone's favourite time traveller. The Doctor (Colin Baker) and Peri arrive in 1985 London shortly after avoiding a collision with Halley's comet, lured by a galactic distress call. They discover that the city's sewers are populated by Cybermen, intent on changing history by preventing the destruction of their home planet, Mondas (see 'Doctor Who: The Tenth Planet'). It transpires that the distress call which attracted the Doctor's attention was sent by none other than former Dalek ally Commander Lytton, but just whose side is he on this time?

The first story from the final season of Sylvester McCoy's tenure as the Doctor. The Doctor and Ace arrive on Earth in the late 1990s where they become involved in a battle between King Arthur and Morgaine. However, these are not the heroes of Britain's past but warriors from another dimension - and they recognise the Doctor as the wizard Merlin. As usual it is down to the Doctor and Ace to save the planet, but this time they find some help in the guise of the Doctor's old UNIT ally, Brigadier Lethbridge-Stewart.

Two episodes from the Tom Baker era 'Doctor Who', devoted to the Doctor's favourite metallic pooch - K9. In 'The Invisible Enemy', a mysterious cloud is causing havoc in space, infecting all those who pass through it with an intelligent virus which could spread throughout the whole galaxy. The Doctor (Baker) and Leela (Louise Jameson) try to come to the rescue, but the TARDIS passes through the cloud itself, leaving the Doctor infected with the virus. He and Leela then try to find help at a nearby medical station, where they meet the eccentric Professor Marius and his pet robot K-9. In 'K9 and Company', the pilot from the 'Doctor Who' spin-off series, the Doctor's former companion, Sarah-Jane Smith (Elisabeth Sladen), arrives to take up residence with her Aunt Lavinia at the village of Moreton. She finds the house deserted apart from a crate marked for her attention, which turns out to contain a gift from the Time Lord: K9 Mark 3. The mechanical dog teams up with Sarah to investigate Aunt Lavinia's disappearance, and together they unearth evidence of witchcraft.
