->''Isn't it obvious?... You and me, Shinji Ikari. We're going to save the world.''

''Series Thirty and Three Quarters'' (also known as ''Shinji and the Doctor'' and ''Doctor Who: The Evangelion Error'') is a ''Series/DoctorWho'' / ''Anime/NeonGenesisEvangelion'' crossover written by a troper known variously as philopoemen and machiavelli. One miserable, rainy day, fourteen-year-old Shinji Ikari meets a very odd man who calls himself the Doctor (specifically, [[Creator/DavidTennant the Tenth Doctor]]) on a train. Unfortunately, something ''else'' has followed them on-board. That's when the screaming and the running starts... and when Shinji's life starts to change. Because the Doctor is in, and where he goes, chaos is sure to follow...

The series serves two purposes: first, it's an excuse to have the various unresolved questions and mysteries of the Evangelion universe investigated by a - let's say - ''[[CrazyAwesome uniquely]] [[MrExposition qualified]] [[GuileHero individual]]''. Second, it gives Shinji a [[EccentricMentor mentor figure]] who - while having his own issues - still brings [[ReallySevenHundredYearsOld a lot of experience]] to the table. The question is, will it be enough to change the destiny of humanity?

!!In addition to the character tropes present in the original work, this story provides examples of:
* ADayInTheLimelight: Episode 5 is this for Shinji's classmates.
* AndIMustScream: The Doctor points out that the Evas are living beings trapped inside metal shells and are only allowed to move when a pilot is inserted into them.
** [[spoiler: Lilith, who is nailed to a cross in Central Dogma, constantly screaming for help]]
* AuthorTract: [[WordOfGod The author admits]] that the Doctor's speech to Misato is this, pointing out the {{FridgeLogic}} how Shinji barely has enough support to cope with and how eventually he'll reach the breaking point of becoming another ChildSoldier like Rei.
* BadassBoast: The Doctor delivers a pretty nonchalant one when Shinji asks how long it should take to get through the door to the main LCL plant.
-->'''The Doctor''': "Eh. Call it at fifteen minutes? Ten if I don't break for snacks."
* ChronicHeroSyndrome: Rei is apparently a follower of [[ThreeLawsCompliant Asimov]], and thus goes out of her way to save the other students in Episode 5.
** This is part of Shinji's character development as the Doctor's influence causes him to graduate from ReluctantHero.
* ContinuityPorn: As to be expected from a Doctor Who fic.
* CoolTeacher: The Doctor teaches Shinji's class English, History, ''and'' physics.
* DangerouslyGenreSavvy: [[MagnificentBastard Gendo]] who [[spoiler: is the only person to figure out that the Doctor is a non-angel alien from another world]]
* GroinAttack: [[spoiler: Misato delivers a particularly vicious one to the Doctor.]]
* HistoricalInJoke: Plenty, as per usual with The Doctor
* InsomniaEpisode: The first half or so of Episode 6 is this for Shinji, with circumstances constantly keeping him awake.
* LampshadeHanging: Done pretty often, usually by Shinji.
* MistakenForGay: Asuka does this to The Doctor and Shinji from episode 6 onwards, after they continually ignore her for their own conversation.
* NotSoDifferent:
** The Doctor sees a lot of himself in Shinji, and decides to stick around to help him.
** The Doctor and Misato are this as well, being the only two figures of any authority who proactively care for Shinji despite wildly different methods and ideologies.
* OnlySaneMan: [[spoiler: Somehow the Doctor ended up in this role and hates it.]]
* OtherMeAnnoysMe: The Doctor regularly converses with hallucinations of [[TheNthDoctor his past selves]], and is more often than not irritated by their presence. WordOfGod says that the feeling is mutual. The fic is set immediately after [[Recap/DoctorWhoS30E16TheWatersOfMars "The Waters of Mars"]], and the previous Doctors aren't exactly happy with Ten at the moment.
* PetTheDog: Expect The Doctor to do this at least once for Shinji in every scene they share.
* PhlebotinumBreakdown: The Doctor's TARDIS is broken due to him crossing into another universe. Meta-wise, this is to give the Doctor an excuse to stay and help Shinji instead of running off
** The Doctor's sonic screwdriver breaks [[spoiler: just as he was about to close a space-time rift to stop an angel traveling from the future]]
* PopCulturedBadass: The Doctor's plan for Shinji seems to be this as he gives him lots of books to read [[spoiler:and it seems to work as shinji starts to make shout outs and actually cracks a joke!]]
* TheRealHeroes: When Shinji asks why he should save people, The Doctor points to the Japan Heavy Chemicals volunteers who despite not being alien geniuses or mecha pilots are still risking their lives to help fight an angel in their own way.
* ReasonYouSuckSpeech: The Doctor delivers a pretty quick one to Asuka if for no other reason than to make her shut up.
* SecretKeeper: Shinji, of course.
* ThereAreNoTherapists: And The Doctor notices.
* TechnoBabble: Often.
* TimeyWimeyBall: Episode 6 has a whole bunch of time travel and time-related shenanigans.
* TwoTeacherSchool: The Doctor ended up teaching English, Chemistry and History because [[spoiler: the other teachers either died or are recovering from being turned into zombies.]]
* WhamLine: "...who's that?", directed from Shinji to [[spoiler: the Ninth Doctor]]
* WhatMeasureIsANonHuman: The Doctor makes the argument that even though Rei isn't ''human'', she's still a ''person'' and should consider herself as such.
