The Time War Dalek has such advanced weaponry that nothing in the known universe could ever hope to stop it. There is a reason the Last Great Time War was severed from existence after all. It cleaved through planets with the intensity of a supernova compressed into a beam of less width than your arm. The Gallifreyans had to think of some countermeasure, and somehow managed to outfit their TARDISes with shields that could withstand such blasts. However, only TARDISes that served in the Time War had those shields, and with said war retconned out of existence (retcon being the informal term for time-locked), it seems unlikely that there is any hope for any unfortunate soul caught in a Time War Dalek's path. This has been another helpful note form the Time Lord Hitchiker's Guide to the Multiverse.

Oh wait.

The gunstick beam fizzled out of existence as a strange blue box faded into existence in front of the Enterprise. Even without air in space, the ethereal VWARPing of the TARDIS materializing could be heard in every fiber of every being within sight. Including the Dalek.

DOC…TOR!?

DOCTOR! EXTERMINATE! EXTERMINATE!

Multiple blasts were fired but none left so much as a scratch on the most powerful ship in the universe. The Doctor took this opportunity to peak his head out.

"Hello Dalek. Miss me?"

DOCTOR!

"I knew you would. Hey, you know what? I've got something for you. Here, catch!"


Onboard the Enterprise, Kirk, Spock, and the rest all looked on at the scene below. After zooming in with the viewing screen, Kirk uttered a statement of disbelief.

"Did he just throw tribbles at it?"


Onboard the TARDIS, Clara uttered a similar statement of disbelief.

"Tribbles? This was you big plan? You're fighting the most powerful, evil, crazy, mad, evil alien in the universe and you go with tribbles?"

"Yes. Yes I did. Trust me. I'm the Doctor (cue epic theme song)"


The Dalek was momentarily confused by these purring puffballs floating towards it. The confusion didn't last long however.

EXTERMINATE!

The dalek fired, instantly vaporizing the poor tribble caught in its blast.

EXTERMINATE! EXTERMINATE!

The Dalek fired repeatedly; the tribbles it did not hit directly were still killed by the glancing blows. Having put all evolutionary energy into being cute, there is absolutely no way for a simple tribble to survive a dalek.

But one thing the dalek did notice, is that even as it killed endlessly, the total population of tribbles did not seem to be decreasing.


"Alright Doctor, what exactly did you do to Skaropuff?"

"I cloned him, and this time kept his reproductive faculties intact. Then I integrated him with this"

The Doctor pulled out a Cybermite.

"You remember this little guy? I kept one as a souvenir. Cybermen, while a horrible creation, are fascinating from a technological point of view. They are constantly adapting and upgrading to their surroundings, maximizing and amplifying the traits of species they take over. Now what would happen if I combined that, with a species that does nothing but reproduce and survive by sheer numbers?"


Daleks are always hateful and frustrated. This one however, is even more so. The mass of cybertribbles constantly grew, for every ten that died, hundreds sprang up in their place, only to mature in an instant and multiply again even before the dalek could fire a second shot.

DOES NOT COMPUTE! WHY WON'T THEY DIE! EXTERMINATE! EXTERMINATE!


The Doctor continued his explanation.

"I've contained the tribbles and the dalek in the TARDIS's shields so that no stray blasts will hit us or anything around. All that I've done here is recreate a secondary school biology experiment. Add the predator, add the prey, isolate the environment, and watch it go. But here's the catch, while the prey can evolve over time, the predator cannot. The predator stays the same as the prey evolves and adapts with exponentially increasing generations per second. And that will be the Dalek's downfall because if there's one thing a Dalek can't kill, its good old natural selection! Life will find a way!"


The Dalek spun as it fired continuously. Fuzz and ashes flew into the air as the dalek exterminated everything as smoke filled the force field obscuring the view of everyone watching the scene.

After a few long minutes, the smoke cleared. A single tribble floated in front of the dalek. It wasn't multiplying; something must have gone wrong in its birth.

If the dalek could smile, it would. But it can't. So it shot instead.

EXTERMINATE!

The dalek fired straight and true.

The tribble purred contentedly.

EXTERMINATE!

The dalek fired again.

The tribble continued to purr.

EXTERMINATE!

The gunstick fired its full power, its maximum payload, explosions ricocheted off the walls of the TARDIS's force field as energy that could destroy stars flew through the tribble.

And the tribble continued to purr.

WHAT. ARE. YOU.


The Doctor held the original unaltered Skaropuff up to the window.

"You kept the original?"

"Of course I did! I couldn't kill this little guy! See that there Skaropuff, that's your grandson, Skaropuff the...forty six gazillionth. And he has beaten a dalek. Aren't you proud?"

The Doctor gave Skaropuff back to Clara, as he poked his head out of the TARDIS doors yet again.

"You see now dalek? That tribble there cannot be killed by your gunstick! Now, what does a dalek do when it has no other way of killing its target?"

A tense silence followed.

The dalek broke the silence.

….EX…TER…MINATE

The dalek emitted a bright glow as the orbs on its lower section flew off and surrounded both the dalek and the last tribble.

YOU WILL BE EXTERMINATED! RESISTANCE IS FUTILE! SELF-DESTRUCT ACTIVATED!

And with that, the orbs formed a force field of energy that then imploded, detroying the dalek and the tribble in a flash.


The TARDIS materialized on the bridge of the USS Enterprise.

The Doctor and Clara stepped onto the bridge, to a silence filled with amazement and apprehension.

Spock broke this silence

"Doctor. That was a rather…unorthodox way of handling the situation."

"Well, you could say that, but it's not like your lot here were doing any better. Now, I'm terribly sorry for the inconvenience I've caused and I had best be going home soon. But before I do that, allow me to tow you back to Earth."

As the Doctor turned to leave, the other doctor interjected.

"Sorry Doctor, but I'm just wondering, do you have any of the tribble clones left? I'd have it sterilized obviously, but you took our only specimen."

The Doctor responded to the other doctor.

"I'm a Doctor, not a tribble breeder. I don't have any spares, but Skaropuff's home is with you after all. Clara?"

The Companion returned the contentedly purring puffball back to its owners.

"Now then, shall we be off?"

And so the TARDIS towed the Enterprise back to Earth, making sure not to be spotted by any satellites along the way. Following this, the TARDIS dematerialized once again, making its way home in a puff of plot convenience.


Once they were back on Earth, Spock filled out their debriefing report. Kirk would have done it, but both of them knew that no one would believe what they had just seen. So Spock had better do it. It would be more believable coming from him.

The following excerpt was kept in the Captain's Log.

"Having seen so many things in the universe, and as illogical as it is, I cannot say I have ever seen anything so close to pure evil as the Dalek. It is highly unsettling that such a thing could exist, not even mentioning the power it possessed. The mysterious Doctor is another enigma entirely. While he acts the fool, I am sure that he knows the consequences of his actions. There is an air about him much older and darker than he appears. I am very glad he is friendly and almost just as glad that he is gone.

As a final thought, after so many generations, I highly doubt that whatever organisms the dalek was fighting could still be classified as tribbles. That last survivor especially. We may have just seen the birth and extinction of an entirely new species. It is almost unbelievable that a single man can play god that easily. I hope that technological progress in our universe will not follow such a dangerous path."


Aboard the TARDIS, Clara petted Skaropuff. She also had a question.

"Doctor, why didn't you tell them we made extra copies of Skaropuff?"

"Well we just saw one destroy the most dangerous alien in the universe. I don't think they would have very well let us leave with it."

"But this one is safe though right? No cybertech things going to make them take over the world or anything like that?"

"Nope! This little guy is right as rain. Might as well be a paperweight, but cuter."

The Doctor took Skaropuff the Second and placed it back in its box.

"Alright. Ready for a ride?"

The companion braced herself and smiled.

"Geronimo."

The Doctor flipped a lever and the TARDIS control room shook as the Doctor and his Companion flew off to their next adventure.


In the inky blackness of space, a lone tribble floated alongside the ruins of a dalek.

It had survived.

The cybermite implantations sparked and hummed. If the tribble had a sentient brain, it would hear the dalek's last message being repeated by the cybertechnology over and over again, as it floated through the abyss.

Resistance is futile…..resistance is futile…resistance is futile…..


Note from the author: Sorry if I got a lot of the Star Trek aspects wrong, I'm honestly not a Star Trek fan beyond the Abrams movies, but I took what I could form the few TOS episodes I've seen.

This is what my friend told me to write: An epic tale where the TARDIS landed on the Enterprise and the Doctor somehow brought about the birth of the borg with his cybermen knowledge and daleks get un-locked from the time war again and Spock tries to talk logic with them about how exterminating everything else kind of defeats the purpose of ruling supreme. and stuff. but more awesome.

I hope I fulfilled your expectations =)
