''Series/StarTrekTheNextGeneration[=/=]Series/DoctorWho: Assimilation[[superscript:2]]'' is a 2012 comic book miniseries from IDW that is a crossover of ScienceFiction LongRunners ''Franchise/StarTrek'' and ''Series/DoctorWho''.

The premise of the story is that the Borg and the Cybermen have formed an alliance, and that [[Creator/MattSmith the Eleventh Doctor]], along with companions Amy Pond and Rory Williams, have to team up with the crew of the U.S.S. ''Enterprise'' (NCC-1701-D) to stop this formidable menace.

The miniseries is eight issues long.

----
!!''Star Trek: The Next Generation[=/=]Doctor Who: Assimilation[[superscript:2]]'' provides examples of:

* ActionHero: Kirk fights against a Cyberman barehanded, and though losing it's ''awesome''!
* AllYourBaseAreBelongToUs: The first issue opens up with an invasion of Borg and Cybermen.
* AndNowForSomeoneCompletelyDifferent: Issue 3 revolves around [[Series/StarTrekTheOriginalSeries Kirk and crew]], teaming up with [[Creator/TomBaker the Fourth Doctor]] against '80s-era Cybermen.
* AnotherDimension: Hinted at twice in the second issue. The Doctor, who claims to know every star and planet out there, identifies Worf as a Klingon, but then informs Amy and Rory that until seeing him [[RippleEffectProofMemory he'd never heard of a Klingon before.]] Later, when Picard receives the DistressCall from Delta IV, the Doctor [[LampshadeHanging reminds us of his familiarity with the whole of the universe]] and then states he's never heard of Delta IV. Guinan confirms the multi-dimensional nature of the conflict in ''Issue 5'', explaining that part of what makes the Cybermen so dangerous is their awareness of and existence in multiple dimensions, and how assimilating the Borg and their resources would make them powerful enough to expand across and take over all of reality.
* ArcWords: When Picard first mentions the Battle of Wolf 359, the Doctor manages to connect the name to Bad Wolf.
* ArtShift: When the story flashes back to the Fourth Doctor meeting Captain Kirk and crew, the artwork shifts away from J.K. Woodward's painted/photorealistic artwork (for the ''TNG'' scenes), to the Sharp Brothers' poppy Sixties look (for the ''TOS'' scenes).
* TheAssimilator: Both the Borg and the Cybermen, as per usual. [[OhCrap Now working in tandem.]]
* BackstoryInvader: The merging of the two universes [[CosmicRetcon creates some alterations to the past]], most notably the Fourth Doctor having met up with the ''TOS'' crew in the past, which Eleven insists he has no memory of in the "present"[[note]]For lack of a better term to use for someone like the Doctor[[/note]], but also ''does'' remember it at the same time.
* BadFuture: The Doctor uses the TARDIS to show Picard one in which the Cybermen succeed in assimilating the entire universe, in order to fully drive home the severity of the situation and persuade him to accept the Borg's help in stopping them.
* BiggerOnTheInside:
** No points for guessing what object elicits this observation from Captain Picard.
** The TARDIS again elicits this reaction in Issue #7 when a small Away Team board, except for [[spoiler:Data, who is more intrigued than confused.]]
* BlatantLies: Amy accuses the Doctor of this after he tells Picard and the ''Enterprise'' crew that crossing their own timeline to visit the Battle of Wolf 359 is a huge mistake.
* BorrowedCatchphrase: The series kicks off with a Cyberman using the Borg phrase "Resistance is futile.", though it was the Cybermen who [[OlderThanTheyThink said that first]].
* CasualDangerDialogue: The Doctor is in top form in Issue 1, as he discusses the potential for various injuries while on a chariot.
* CharacterCatchphrase: An oldie but goodie shows up in the third issue, when the Fourth Doctor asks "Would you like a jelly baby?" Spock is greatly intrigued.
* ChekhovsGun: Or Chekhov's Planet in this case - Naia VII.
* ContinuityCavalcade: The trip forward in time the Doctor shows Picard in the BadFuture shows Vulcan, the Klingon capital (including Cybermen with Bat'leths), converted Judoon and Raxacoricofallapatorians.
* ContinuityNod: Several for each series.
** Issue 5 has Picard recount the events of "[[Recap/StarTrekTheNextGenerationS3E26S4E1TheBestOfBothWorlds The Best of Both Worlds]]", Parts 1 and 2.
** Issue 6 recalls [[ArcWords "Bad Wolf"]].
** Issue 6 also has Amy reference the events of "[[Recap/DoctorWho2010CSAChristmasCarol Doctor Who: A Christmas Carol]]" when calling the Doctor out on BlatantLies.
** Issue 6 also has the Doctor, Amy, and Rory arrive at the Battle of Wolf 359, where they encounter Locutus.
** Rory mentions he [[Recap/DoctorWhoS31E13TheBigBang was a plastic Roman at one point]]. And [[TheyKilledKenny being dead]].
* CoolShip:
** The TARDIS and the ''Enterprise''-D, natch. Issue 2 even has the Doctor complimenting the design of the ''Enterprise'''s bridge.
--->'''The Doctor:''' Lines. I like the lines.
** Though the Doctor does note in issue 7 that while the ''Enterprise'' is a fine ship, he'd rather have his TARDIS under his feet in a crisis.
* DistressCall: The ''Enterprise'' receives one while Picard is talking with the Doctor, regarding the attack on Delta IV. Garbled and incomplete, they don't learn who is responsible until they arrive.
* EnemyCivilWar: As of issue 4, the Borg and the Cybermen are now warring amongst each other, with the Federation seriously considering the option of simply sitting back and allowing their most hated enemy to be wiped out, in spite of the Doctor's warning that the Cybermen are emphatically ''not'' their friends.
* EnemyMine: In the face of total Cybermen domination, the Doctor makes it clear that the only way to survive is for he and the ''Enterprise'' crew to temporarily ally themselves with the Borg - a decision that Picard is obviously ''not'' happy with, given the torture he previously endured at the Borg's hands.
* EvilOverlooker: The Cyber-Borg Controller appears as one on the [[https://vignette.wikia.nocookie.net/startrek/images/7/7d/Assimilation2Issue8_Cover_A.jpg/revision/latest cover]] of the final issue.
* TheFarmerAndTheViper:
** More of a case of the Viper and the Viper, seeing as both the Borg and the Cybermen team up, knowing fully well that the other would try to assert dominance over the alliance at one point. The Cybermen were just ''better'' at it.
** When the Cybermen are defeated, the Borg try to turn on the heroes almost instantly. Everybody saw it coming, and they were prepared.
* FateWorseThanDeath: Assimilation and Cyber-conversion.
* {{Flashback}}: The Doctor has one in the third issue, to his days as [[TheNthDoctor the Fourth Doctor]], meeting [[Series/StarTrekTheOriginalSeries Captain James T. Kirk and crew]]. Somewhat subverted in that the Doctor says that [[RippleEffectProofMemory he also remembers that incident NOT happening]].
* FishPeople: The Dai-ai of Naia VII, although Counselor Troi NEVER used the term "fish people".
-->'''Troi:''' I said they were [[InsistentTerminology aquatic humanoids]]! Amphibious!\\
'''Worf:''' [[DeadpanSnarker They sound delicious.]]
* GibberingGenius: The Doctor, as usual, to the point that Worf asks him to please stop talking.
* HiveMind: The Borg and the Cybermen, per usual. How combined those hives are has yet to be seen, though so far we've seen a Cyber Controller outfitted with Borg technology. [[spoiler:Not very, as it turns out. Not only do the Cybermen turn on the Borg and almost destroy them but that was their intention all along.]]
* LesserOfTwoEvils: Eventually, the Borg.
* LetsYouAndHimFight: Picard attempts to [[InvokedTrope invoke]] this trope and let the Cyberman and the Borg wipe each other out, content to rid the galaxy of the scourge of the latter. The Doctor has to show him that doing so causes the Cyberman to not only win, but take over the entire Federation in the process, leading Picard to back off.
* MythologyGag:
** When the TARDIS crew explores San Francisco, they come across Tom's Bakery on 4th Street. Creator/TomBaker, of course, played the Fourth Doctor.
** As with ''Series/StarTrekVoyager'', the Federation is forced into an alliance with the Borg to defeat a greater evil, knowing full well they'll be betrayed when it's all said and done, and are prepared when said betrayal inevitably happens.
* NiceJobBreakingItHero: While there wasn't a lot he could do about it, the Borg's experience with the Doctor leads to them determining to master time travel, likely leading to [[spoiler:the events of ''Film/StarTrekFirstContact'']].
* NoSell: Borg Assimilation doesn't work on Cybermen. Conversely Cyber conversion seems to work fine on the Borg. This could be an example of FridgeBrilliance -- Borg assimilation involves injecting nanobots into the victim, which start "Borgulating" them from the inside out. Cybermen contain little-to-no remaining organic tissue, and so cannot be "Borgulated".
* OhCrap:
** The Doctor and Picard have a simultaneous moment of this when they spot the Cybermen/Borg ships in orbit over Delta IV.
** The Doctor has another moment when he is spotted by Locutus at the end of issue 6.
* OrcusOnHisThrone: The Cyber-Controller.
* RippleEffectProofMemory: The Doctor demonstrates this ability in the second issue, but with a variation: he states he actually ''feels'' his memories changing, and says he didn't know what a Klingon was until he laid eyes on Lt. Worf. Later on, after a flashback to his Fourth Doctor days and a meeting with the ''TOS'' crew that he knows never really happened, he notes that if his memories are changing, then they're in even worse trouble than he initially thought. Because of all this, Picard takes him to meet another time-sensitive alien with Ripple-Effect-Proof Memory: Guinan. See also SequelHook.
* SaveTheVillain: In order to defeat the Cybermen, the Borg collective must be restored.
* SequelHook: [[spoiler:The Borg remember everything that happened, and plan to master TimeTravel.]] This works great whether there's a sequel or not -- if there isn't, then [[spoiler:this story helps to set up the events of ''Film/StarTrekFirstContact'']].
* ShoutOut: Bordering on AscendedFanon: the Fourth Doctor meeting Captain Kirk and the crew of the ''Enterprise'' is similar in many ways to a popular crossover fan fiction, ''The Doctor and the Enterprise'', wherein the same scenario occurs.
* SingleBiomePlanet: Naia VII seems to be an ocean world.
* {{Teleportation}}: The Doctor is amazed at the transporters. (Probably unlike the Transmats, they can teleport more than three people at the same time.)
* WackyWaysideTribe: Issue 1 starts out with the Borg/Cybermen invasion of Delta IV, followed by the Doctor, Amy, and Rory capturing a fugitive alien in ancient Egypt before landing on the ''Enterprise'''s Holodeck during a Dixon Hill program.
* WhatHaveIBecome: Inverted. [[RidiculouslyHumanRobots Data]] explains at the beginning of Issue 2 to Geordi that this is the reason he doesn't upgrade his hardware, as he would wonder, over time, how much of him was left in a reinvented self.
** This also, basically, sets up the issue with the Cybermen...AND the Borg. As they both did the same, and the answer is 'not much'.
* WhatTheHellHero: Riker has this reaction to the Doctor after he encounters an old friend of his who was assimilated by the Borg.
