|'The Three Doctors'
Story Code 'RRR'
by Bob Baker
and Dave Martin
A blob of animated energy arrives on Earth in a cosmic-ray research balloon, multiplies into gel-like monsters, and quickly hunts down the Doctor. Retreating to the safety of the TARDIS, together with JO, Brigadier Lethbridge-Stewart and Sergeant Benton, the Doctor is forced to call on the Time Lords for help. Unfortunately, the Time Lords themselves are in a crisis, as their energy is being drained by a black hole. All they are able to do is send the Doctor's first and second incarnations to aid him. The First Doctor is caught in a time eddy, and is only able to advise, and deduces that the gel-creature is a time bridge. The Third Doctor and Jo give themselves up to it, and are transported through the black hole into a world of anti-matter. On Earth, the Second Doctor, on the advice of the First, switches off the TARDIS's force field, and the whole UNIT building is also transported through the black hole. Behind these events is Omega, a figure from the Time Lords' ancient history, whose solar engineering prowess provided the power for their time travel, by utilising the energy from the black hole. Omega has been trapped in the black hole ever since, and now wants the Doctor to swap places with him, so that he can return to his home planet. But the corrosive properties of his anti-matter domain have already destroyed his physical form, leaving only his will, which alone controls his world. Omega threatens to destroy the universe, but is tricked into touching the Second Doctor's recorder - the only thing not converted to anti-matter when the TARDIS passed through the black hole. Omega is consumed in the resulting supernova, the energy of which replenishes the Time Lords' reserves. The First and Second Doctors are returned to their respective timelines, and the Doctor's exile on Earth is lifted as his reward, leaving him free again to travel through time and space.
