This is the crossover fanfic in my fan-series which features a parallel universe Moonbase Alpha (Space:1999) as it would occur in Universe-777 (the Stargate & Doctor Who universe).

Story (C) 2007-2015 Mr SciRev

Previous episode: AlphaGate 7

For the Stargate Timeline, it happens after Stargate Atlantis 4×3 and the Stargate Continuum movie.
For the Doctor it occurs after the first Star Trek (2009) reboot universe fanfic on this site which can be found here.

SPOILER: V: The Original Series.

What you need to know:
“The IOA (International Oversight Advisory) has set up a top secret base on the moon powered by a ZPM (Zero-Point Module) – an ancient power source. Stargate Command has commissioned special crafts called Eagles and a Stargate – a ring-like device created by the Ancients able to send people through a wormhole – but one without a protective iris. A separate section on the moon houses a super-hadron collider. A mysterious hyperdrive in the catacombs of the moon has been activated, catapulting the moon to an unknown area in space.The moon ended up sliding through different parallel universes..
Meanwhile back on Earth-777, another moon has just materialised in the place of the missing moon. Aboard the moonbase are reptilian aliens known as the Visitors. They had attempted to bombard earth’s Stargate but failed thanks to the iris.

The Doctor is an alien explorer through time and space, going to amazing and terrible places in the universe, armed with his fantastic sonic screwdriver. The Tenth Doctor is currently travelling with Spock Prime.



Shots were heard. The Alpha encampment which was the only trace of civilisation on this parallel earth was being attacked. But by whom? Wasn’t all of humanity on this earth dead ?

Victor looked up towards the sky and saw an army of flying invaders.

“What can these be?”

Sandra looked and recognised them. She had read about them, in some books about mythology. These creatures were the Mindless Ones, dangerous beasts whose dimension was melded to the Dark Dimension.

So they were real. And they threatened to destroy the last remnant of humanity in this universe.



Suddenly an Eagle came in flying close-by. It was the Eagle sent in from the moon which had slided into this Universe. Daniel Jackson, Teal’c and  John Koenig were in the Eagle, which began firing laser beams towards the Mindless Ones.

They were pushed back, but only slightly. This was not going to defeat them, that was clear.

Daniel contacted Moonbase Alpha with an order to fire the Tolan Cannons. If anything this should work, he thought. The Cannons from the moon fired towards the Mindless Ones. It was amazing that they could fire with such precision from orbit, however this amazement soon gave way to fear when it was clear that the invaders were unharmed.


The Mindless Ones continued their attack undaunted, destroying the Alphan huts on this earth.


Professor Victor Bergman – the one from this earth’s encampment  and not our Alpha’s Victor – decided to try and lure them towards a narrow mountain path.  Then they would have to pass one by one. But how could he destroy them? He couldn’t.


Earth-616, a few years ago.

He was in his Sanctum Santorum, a three-story townhouse located at 177A  Bleecker Street. It was located in the heart of New York City’s Greenwich Village.  Those who have entered his house, have always said that his house was bigger inside than outside, well it was dimensionally transcendent.

His name was Doctor Strange, this universe’s Sorcerer Supreme and protector.  He thought about how he had been so proud of his talent as a Surgeon, how he had had such a big ego, until he ruined his life himself, partying hard, crashed his car and ended up unable to operate with his hands.

That was not the end of his life though. He heard about the Ancient One, a Tibetan Master, and utterly resolved to find him. He was in Tibet and there he became his Disciple, not without making a new enemy, Mordo, the Ancient One’s original disciple who was plotting to gain unholy power from Dormammu, Lord of the Dark Dimension.

He would become Sorceror Supreme and still keep facing Dormammu from time to time, though he did this also with the help of Dormammu’s daughter, Clea. Clea and Strange had gotten married only recently.

Today he was in his study and he was looking in his Orb of Agamotto, seeing a distant scene which, at first unfocused, soon became quite clear. It was a group of Mindless Ones, from Dormammu’s Dark Dimension, attacking a group of people in a small settlement. But this was not in his universe and it had not happened yet. It was going to happen in the future of Earth-702 , i.e. the Earth of parallel Universe-702. He decided to get involved and made preparations to go there.


Moon-777, The V-Moonbase

The Tenth Doctor is held prisoner by Diana on the moon in Universe-777. Suddenly an explosion was heard.
“Yes that was me.” the Doctor continued. The weapons stores kept blowing up. “I also saw your conversion chamber and disabled it entirely. You’re not ‘converting’ anyone soon.”

“I have captured your friend” Diana answered. “I will have him killed for your insolence, human”
“Oh I’m not human. I’m a Time Lord. From the Planet Gallifrey!”
Diana suddenly looked worried but she was acting. “Is that supposed to scare me into submission? What the heck is a Time Lord?”
“Oh now I see, you’re not even from this Universe.”

Diana fell to the floor, an even larger explosion was heard. The Doctor was free as the containment shield blinkered out into nothing. Something else must have happened, he thought. Not just his explosions. He looked at a screenviewer, and could see a large ship in orbit around the moon.

The Sun Tzu a 304 ship –  with Sam and Rodney on board – had fired at the V Moonbase, hitting it and causing damage.

Suddenly a phasing effect was appearing on the moon. The Sun Tzu must have hit the hypersliding mechanism and triggered it.

The moons started sliding and disappeared, only to be replaced by another moon, from the viewpoint of the Sun Tzu.

“What? Another sliding event?” Rodney was panicking.
“Yes, at least we were not too close or we would have been sucked in”, Sam said.

Meanwhile, the Doctor left to try to find Spock-Prime quickly. Spock was still captured in another section of the Moonbase, but most systems were now down, so the Doctor liberated him (he did trick the guard with some Psychic Paper) and, avoiding most of the other guards, they went back to the TARDIS.


Daniel Jackson was in contact with Alpha on the moon, busy hiding from the Mindless Ones which were still attacking the encampment.

Suddenly he was cut off, and the moon shimmered out of existence and another moon – the Post-SpaceWar Earth’s Moon Slid replacing it.

He wondered, where did their Alpha go to, to which Universe?

The Doctor’s TARDIS in another Universe

“Yes, my friend Spock, we are in another Universe. The moon has shifted to another universe. That wasn’t Earth-777’s original moon either. The TARDIS confirms that now.”

“So, which universe is this?”

“The Void! The Void between universes!”

“and that is?”

“Dangerous!”, the Doctor added. “It’s the bleed between universes! There’s Daleks here, even Cybermen”
