Doctor Who: Regeneration/Crossover Stories

The adventures in time and space of the Doctor, a Time Lord who changes appearance and personality by regenerating when near death, and is joined by companions in battles against aliens and other megalomaniacs.

The TARDIS arrives on the Earth colony of Vulcan where the newly-regenerated Doctor assumes the identity of an Earth Examiner.

In 1974, the original tapes for "Power of the Daleks" were wiped from the BBC Archive. After 50 years, the BBC has animated this lost serial for a new age. In the original, the Doctor (Patrick Troughton) has just regenerated or has been "renewed". His companions, Ben (Micheal Craze) and Polly (Anneke Wills), are unsure of this new man. Is he the old man they departed London with? But the TARDIS lands on the planet Vulcan, and soon the Doctor and his companions are mixed up in the death of an Earth examiner, a colony from Earth and a rebellion against the colony's current government. But, a scientist named Lesterson (Robert James) had foolishly tampered with powers he can't control. Now, the Daleks are planning on destroying the colony, and only the Doctor can stop them!

The TARDIS is drawn to the planet of the Time Lords where both the Doctor and the War Lord are placed on trial.

As the newly regenerated Doctor arrives on Earth, so does the Nestene.

Can the Doctor, now in his fourth incarnation, recover from his post-regenerative trauma to save the Earth from Think Tank and their plot for world domination?

Forced to work together to save the universe from collapsing, the Doctor, the Master and Tegan use the Master's Tardis to travel to a giant satellite dish on Earth. Meanwhile Adric and Nyssa are taken to safety by the mysterious Watcher.

The Doctor has regenerated but it hasn't gone well. He's mentally unraveling and needs a place to rest beyond outside influences. Unfortunately the Master has laid a trap for the TARDIS that denies the Doctor undisturbed recovery time.

Chellak and his men attack Jek's base. The Dr. crash-lands the ship, and must escape from his captors to find the antidote to the Spectrox poisoning and save Peri. He does so, but at a staggering cost.

The Doctor and his previous incarnations are brought to the Death Zone on his homeworld Gallifrey as part of a renegade Time Lord's scheme.

The Time Lords have dispatched the Doctor (in his 2nd incarnation) along with Jamie to a space research station to see Dastari, the Director of Projects, about dissuading two of his scientists from further experimentations on time travel that are rattling the fabric of time. The Doctor is further alarmed over Dastari's latest genetic experiments, boosting the intelligence of a bestial and carnivorous humanoid race called the Androgum. This secondary concern soon proves the greater problem: the Androgum have sided with the Sontarans to take over the station. The station soon falls and the Doctor is captured and tortured. As his life becomes threatened, elsewhere the Doctor (in his 6th incarnation) passes out while on holiday with Peri - his very existence jeopardized.

Closing in on the goal of time travel, the Androgum and Sontarans get set to double-cross each other. With Peri and Jamie alternately in danger of winding up on the bill of fare, the decision is made to genetically transform Doctor No. 2 into an insatiably carnivorous Androgum, which causes Doctor No. 6 to develop a sudden taste for house cats as he races to not let this change become permanent.

With carnage and decay all about the space station, Doctor No. 6 and Peri continue to avoid the automated defense system trying to kill them, but there's also something alive lurking about with an eye on them as well. Evidence suggests the Time Lords are responsible for all this, but the Doctor refuses to believe it. He may be wrong, and he also fears a pinhole has been poked into the bubble that is the universe, with total and unstoppable annihilation to follow. Far away, Doctor No. 2 is about to be dissected by the Sontarans and the Androgum in order to find the symbiotic nuclei that makes time travel for Time Lords possible.
