This is a crossover fanfic in my fan-series featuring Doctor Who (the Fifth Doctor – as played by Peter Davison in the classic BBC tv series Doctor Who) – and the Sliders. Currently, I’m reposting my older WhoSliders volume 1 series which features mainly the Doctor (pre-time war) and the Sliders plus the 5th Doctor’s companions.

Story (C) 2001-2016 Mr SciRev.

For the Dr Who Timeline Related to this Fanfic, or to read what happened just before this fanfic, please see Who Sliders 4. The story could also be seen as a prequel to ’48 Hours’ (an episode from Season 5 of Stargate SG-1).

What you need to know:
“The Doctor is a Time Lord – a time-traveller from the alien world called Gallifrey who travels in space and time thanks to his TARDIS which looks like a police box, bigger inside than outside. When the Doctor is severely injured or even killed, he will regenerate into a new appearance and body. He is currently in his fifth incarnation (4th regeneration). His thirteenth will be the last.

The Sliders have developed a technique called Sliding which allows them to go to different dimensions or parallel universes, but will they ever find the way to their home universe?

The Doctor with his companions – currently an Australian hostess named Tegan, young irritating genius Adric, alien orphan and technological expert Nyssa and the Sliders – is on a crusade to champion the cause of the innocent, the helpless and the powerless throughout the whole multiverse of multiple universes. The Doctor’s alteration to the Sliders’ timeline has resulted in multiple changes across various multiverse timelines in hypertime. Fixing these holes is an important task of the Doctor which has been sanctioned by an angel of God called the White Guardian.”

Cheyenne Mountain
Jack O’Neil had just informed General Hammond. Earth was about to be invaded by Kromaggs from another dimension. Sam clarified that they were not aliens in the usual sense but the rightful inhabitants of a parallel earth where humanity had not evolved.

Soon afterwards, the Tok’ra had been contacted. The Tok’ra were very similar to the Gou’ald themselves in the physical sense, but they could not be more different in the spiritual one. The Tok’ra were people with a (healthy) fear of God. A respectful and loving fear not the kind of fear when you are afraid, Anise used to emphasise. (Anise was one of the Tok’ra Stargate SG-1 had met) They had good moral values, just the opposite of the Gou’alds. The Gou’alds would have no compulsion to execute genocide, and wipe out whole races and planets. The Tok’ra attempted to keep the Gou’alds at bay, but it was very difficult. The Tok’ra and Earth had an alliance. Sometimes some of the Tok’ra were a bit secretive or did not exactly help as one might expect, but it was always for a very good reason. One would note that the Tok’ra host would mostly be in control, unlike the Gou’ald.

A Tok’ra GDO (Garage Door Opener) signal had been sent through the gate and Stargate Command was ready to welcome the Tok’ra who were coming through the gate.
Jacob Carter stepped through the Stargate. General Hammond, and of course Jacob’s daughter – Sam – were very happy to see him again. “Hi, dad!”
“How’s my favourite SG-1 member doing?”

Briefing Room
The usual briefing took place, and everyone present was brought up to date on all the information which was known about the Kromaggs. The Sliders had been to this earth (Earth-777, a parallel one for them since they came from Earth-001 except for Maggie) some time ago, and since Wade was still being tracked by the Kromaggs at that time, it was certain that this world would be in danger. The Stargate team could be this Earth’s only hope.
Suddenly, while General Hammond was speaking, something unusual happened to the Stargate. There was an off-world activation, yet the Gate computer indicated that there was an error and the wormhole closed abruptly. Sam left the briefing room, as did the others, and entered the control area of the Gate room. With the Doctor’s help, Sam ascertained that something was waiting to materialise on their side of the Stargate even though an error situation was being reported.
Sam managed to detect an SG-1 signal, the usual GDO, plus some patterns for a person stored in the Stargate’s buffer systems. But how could this be? All of them were accounted for unless this was another gate access from the future. The last time this had happened, they had received a note from Jack in the future. Sam mentioned the note about a planet they had to avoid going to. In fact, the mission to go there had been cancelled, last year, as a result. The Doctor looked at the coordinates involved. ‘This looks familiar, he said.’

‘It’s a planet called Skaro. It’s the Dalek homeworld. You must avoid them. They want to build an empire after enslaving humans from the worlds they take over. If they get to know of Earth’s Stargate, they will attempt another invasion of earth so they can have free access to the Stargate network of planets. No, not if but when. We must not allow this to happen.’
