The Five Doctors
The Doctor, Tegan and Turlough find themselves in no immediate danger for once, until the Doctor suffers from repeated, severe pain, claiming that his past is being altered in a way that could endanger him in the present. Somewhere on Gallifrey, long-abandoned machinery from the earliest days of the Time Lords is reactivated and its powers are brought to bear on each of the Doctor’s first four incarnations, snatching each of them from their own timeline and depositing them in Gallifrey’s infamous Death Zone, where the tomb of Time Lord founding father Rassilon stands. The fourth Doctor is trapped in the time vortex and never makes it to Gallifrey. As the various personae of the Doctor join forces, along with many companions, they find themselves fighting a variety of old adversaries – and one new antagonist – for the future of Gallifrey itself.

LogBook entry & review by Earl Green
The Brigadier invites the Doctor to the grand opening of the Parakon Corporation’s space-themed amusement park, Space World. The Doctor, expecting to see fabricated exhibits and faked “creatures” on display, is astonished to see what seem to be actual alien life forms from other worlds – clearly, the Parakon Corporation’s reach extends far beyond the Earth. But Lethbridge-Stewart’s interest is fixed upon an unsolved murder on Space World’s grounds. Chairman Freeth and Vice Chairman Tragan, the operators of Space World, are doing their best to cover up the death, even if it means eliminating an employee who knows what really happened. When Sarah Jane Smith – always in search of a story – stows away aboard Tragan’s spacecraft, the Doctor, the Brigadier, and Sarah’s rookie photographer Jeremy embark on a quest to save her – a quest that will lead to a world whose fate hangs in the balance…and whose fortune is steeped in the blood of innocent bystanders.
The Doctor is summoned to Italy by the Brigadier, whose Uncle Mario has requested help in the face of increasing threats from a New York land baron with mob ties. Apparently, the intimidation tactics are growing in their scope, including what seem to be apparitions of the dead and visions of horrible, unearthly creatures. The Doctor is very worried to discover that something supernatural is gaining a foothold at Uncle Mario’s castle – something which could, if it breaks through, overrun and destroy life as 20th century humanity knows it. With Sarah Jane Smith tagging along, the Doctor finds away to travel back through the time rift from which these visions are occurring, and finds that the apparitions are the result of one insane alchemist’s attempt to touch “the other side.” The Doctor must put these experiments to a halt, even though his presence merely confirms his adversary’s belief that he is succeeding.
Imbued with the energy of anti-time and possessed by the power-mad Zagreus, the Doctor wrestles for self-control and terrifies Charley into hiding within the TARDIS. A familiar face appears to Charley as she hides – the Brigadier, or, more precisely, a TARDIS-projected simulation of Lethbridge-Stewart intended to help her. Its method of doing so, however, is unorthodox to put it mildly: Charley must divine the true nature of the increasingly disastrous situation from a series of metaphors, ranging from her own childhood to a visit to Gallifrey’s past to an insane amusement park where animatronic cartoon characters are slaughtering one another. The Doctor, too, hears from some familiar voices in his own past, coaxing him to regain control of his own mind. But all too late, the Doctor realizes that his body and soul are not Zagreus’ only battleground, and the real battle for the fate of the entire universe is only now being joined.
Liz Shaw looks back on her days with UNIT and the Doctor, recalling an adventure that began with the disappearance of several prominent scientists. The Doctor and the Brigadier are on the case, and Liz goes undercover to see if a suspicious dentist’s office has any connection to the disappearances. The Doctor figures out that the Cybermen are once again trying to stage a quiet takeover of the human race…and Liz herself may be the next victim of their new conversion process.
The Brigadier receives an urgent but cryptic summons from his old friend, Colonel Heinrich Konrad, of UNIT’s force in West Germany. The message brings Lethbridge-Stewart to an ancient fortification, the Kriegskind, which is now home to a secret UNIT detachment. But rather than being greeted by Konrad, Lethbridge-Stewart is met by his distinctly nervous second-in-command, Schrader, who assures him somewhat unconvincingly that nothing is amiss. The Brigadier pulls rank and is horrified to discover that his old friend is in critical condition in the base’s sick bay, claiming to be the only survivor of some unspecified incident and warning that “time is against me.” Later, Lethbridge-Stewart sees for himself what Schrader didn’t want him to see: medieval swordsmen engaging UNIT troops in a pitched battle, capable of wounding men heavily armed with modern weapons but apparently taking little damage themselves. Lethrbridge-Stewart makes an urgent call to his scientific advisor; the Doctor parachutes into the base hours later. Both men stumble across evidence that they are indeed facing yet another threat of alien origin – but this time, UNIT has brought this menace upon itself.
The Doctor is startled when a flashing red light appears on the TARDIS console. The surprise isn’t that the light has never flashed before, but that it is there at all, where there was no light on the console before. And it’s not just one Doctor, but all of the Doctor’s incarnations.
Notes: The War Council shouldn’t be surprised at all that the Doctor can access the Omega Archives; his seventh incarnation was shown to be in possession of Time Lord superweapons that had presumably been with him for quite some time (
(1975), though they have reappeared in novels and numerous times in the eighth Doctor’s audio adventures, and even have their own action figure – not bad for a one-off villain.
