With ''InspectorSpacetime'''s long and storied history, it has managed to gather quite a list of various characters. [[LoadsAndLoadsOfCharacters A]] ''[[LoadsAndLoadsOfCharacters long]]'' [[LoadsAndLoadsOfCharacters list.]]


[[folder:The Inspectors]]
An Infinity Knight from the planet Kayaclasch, the Inspector is our main character, the one who shows us the wondrous bounty of the universe and of history. Because it's not just ''where'' we are, but ''when''.

!!The First Inspector
The first Inspector was played by Leslie French.

A versatile theatre actor who specialized in Shakespearean roles, French at first seemed an odd choice for the patronising, cantankerous, and notably lower-middle class First Inspector. Although pleased by the programme's popularity at first, he left suddenly at the start of the fourth season to avoid being typecast. On television, he went on to appear in such programmes as ''Series/DixonOfDockGreen'', ''Series/ZCars'', ''Series/TheAvengers'', and ''Series/TheSingingDetective''. He returned once to the series, making a brief cameo in the [[MilestoneCelebration 20th Anniversary Special]].

* NobleBigotWithABadge: Especially at the very beginning of the show. He mellows a bit as his tenure progresses.
* OldFashionedCopper: This Inspector, having a more classic "police man" feel about him in comparison to his successors, could sometimes have elements of this trope.

!!The Second Inspector
The second Inspector was played by ChristopherLee.

He has often been summed up as "SherlockHolmes [[RecycledInSpace in space]]", a cold and austere man who nevertheless has a passion for high culture and fine art, always dressed in the latest understated and conservative fashion... except for those battered Wellington boots. When he truly wished to "brood over the cosmos" he would play his ocarina. WordOfGod has said the show was just playing to Lee's strengths as an actor, but this hasn't stopped the popular theory that the change from French's version was somehow a "promotion", prompting a more upper-class outlook.

Lee filmed two IS movies while the First Inspector's televised run was still being taped and aired. These movies, which posited a half-human Inspector, are now considered alt-canon. Following French's abrupt decision to leave the show, hastily conscripting Lee to reprise the role on television was therefore the obvious choice. While his new(-ish) version of the Inspector quickly proved to be quite popular, Lee has never made any bones about the fact that he became the Inspector mainly because it offered a steady paycheque. After his departure from the series, he never reprised the role in film or television, except for the 20th Anniversary Special, where he was persuaded to (literally) phone in an amusing voice cameo. ("Crikey! ''That's'' what you used to sound like?!") The positive reception to this led to him further agreeing to reprise the role in a series of radio dramas which are considered quite good and, more importantly, canonical.

* MoneyDearBoy: A mild example. Lee has never been known to turn down a paying acting job.

!!The Third Inspector
The third Inspector was played by Bernard Fox.

The Third Inspector is well known for his abhorrence of any sort of strenuous physical activity, and his habit of taking long tea breaks at (seemingly) the very worst moments. Continuing the theory mentioned above, some claim that following the events of "The Crime Sports" this Inspector was somehow "retired", even though he pretty much kept on doing what he always had.

Unlike French and Lee, Fox cheerfully embraced the role from the start, came back for a guest appearance whenever he was invited, and has been a beloved fixture at worldwide IS conventions for forty years.

* LetsGetDangerous: This Inspector may not have liked to exert himself, but when he did... watch out.

!!The Fourth Inspector
The fourth Inspector was played by Marius Goring.

Goring was a surprising choice for the Inspector, given the over-full nature of his filming schedule at the time.

The Fourth Inspector is known for his crazily coloured iconic ascot and knee socks, affinity for small sweets—particularly wine gums and sherbet lemons (some suggest that Albus Dumbledore's affection for treats and sherbet lemons was an homage to the Fourth Inspector). He is also known for his extraordinarily high body count.

He returned to the series twice for guest appearances: the 20th Anniversary special and "The Only Inspector."

* DissonantSerenity: It took ''a lot'' to visible rattle the Fourth Inspector.
* TheEeyore: Conversely, he never tended to display a lot of overt humor and good cheer. Of course, he had reason enough to be gloomy.
* KnifeNut: Most metamorphoses of the Inspector used the Optic Pocketknife as rarely as possible, but Four cut a ''slew'' of throats in his time. He's also the only Inspector to use an Optic Pocketknife balanced especially for throwing.
* WhenHeSmiles: Which made those oh-so-rare smiles he ''did'' unleash all the more glorious.

!!The Fifth Inspector
The fifth Inspector was played by Lynda Bellingham.

Bellingham is the first, and so far only, actress to take on the role of the Inspector. She had the absolute worst wardrobe of all the Inspectors, most egregiously a hat that must be seen to be believed. (One expanded universe novel even made it into a sentient life-form.) She also liked ampersands and took to wearing them in the most unlikely of places.

The metamorphosis from 4th to 5th was very difficult for the Inspector to achieve. Continuing the theory mentioned above, some have speculated/joked that after "retirement" comes "death" and then "rebirth" into a new childhood.

Reappeared on the show in "The Only Inspector", only a year after leaving, which was [[LampshadeHanging lampshaded]]: "Too soon! Too soon!".

She later went on to be cast in [[DoctorWho That Ripoff]] as an Inquisitor. The hat she wore in the role was considered by many a wink to her wardrobe as Inspector. (This would be neither the first nor last time That Ripoff stole an actor from IS or gave a cameo role, such as in the case of Landlord's recent role as George the Security Guard in "Closing Time", to an Inspector.)

* ObfuscatingStupidity: Or perhaps "Obfuscating Ditziness". Her wardrobe and carefree exterior was cover for an ice pick of a mind.

!!The Sixth Inspector
The sixth Inspector was played by Creator/GrahamChapman.

The Inspector was one of Chapman's final roles. Defying expectation, Chapman's Inspector was one of the most sombre and monochrome. The extreme colors of the Doctor in That Ripoff at the time was seen as a move by the Ripoff's producers to distinguish themselves from IS.

This was also the era in which some of the serials just got weird (much to the delight of many fans). The most (in)famous example is probably all those [[MuppetCameo puppets]] turning up in the serial "Mindscrew".

* FailureKnight: Nothing ever went right for this Inspector. ''Nothing''. Some fans claim that his taking on Jeffery was symbolic of his failure, while [[spoiler: Jeffery's death shows his [[SpringTimeForHitler failure at failing]].]] And after that, he failed to [[spoiler: recruit any new Associates]] for the rest of his run[[note]]OK, yes, there was Benjamin, but who ever remembers Benjamin?[[/note]]. In his final episode, he is [[spoiler: sentenced to banishment in an alternate universe and can return home only by dying.]]

!!The Seventh Inspector
The seventh Inspector was played by Creator/StephenFry.

Fry had one of the shorter tenures as Inspector and is best known for all of the "what could have beens" and his associates. The scripts, in a [[ExecutiveMeddling misguided attempt]] to rein in the weirdness of the Chapman years, were reduced to repetitive explosive-laden pabulum, while the budget had been slashed to almost the level of That Ripoff. After limping along for three lacklustre seasons, the plug was pulled on the show. The Seventh Inspector is very popular in FanFic because of this, and many like to imagine how the series would have ended if it had hired better writers.

Particularly (in)famous serials include "Cattlefield", in which fans finally got the answer to the age-old question of whether or not the X7 has internal plumbing (The answer is [[spoiler: yes, but, as with many a living thing, it is sometimes problematic.]]) and "Spectre Night", which is [[BrokenBase either]] a load of pro-Creationist rubbish or the one shining jewel of the era.

* TheScrappy: The least popular of all Inspectors. While most blame this on his abysmal scripts, some feel that Fry either just wasn't a good enough actor for the role or was forced by the producers to play the character in a way that didn't utilize what strengths he did have, or both. Chapman's departure only because of his deteriorating health did not help the transition for his successor.
** Ironically, many fans feel that his [[SuddenSequelDeathSyndrome ten-minute appearance]] at the start of the one-off Eighth Inspector movie was [[RescuedFromTheScrappyHeap easily his best acted and scripted work]] as the character. His willingness to do it at all was a point in his favour as well.

!!The Eighth Inspector
The eighth Inspector was played by Creator/SteveCarell.

Carell's turn as Inspector was an early attempt to revive the series after the disappointment of Fry's run. Carell starred in a made-for-TV movie alongside Anne Hathaway who played his Associate, Charity Galloway. Many (though not all) fans prefer to pretend this movie never existed and sometimes choose to disregard the movie as canon. (It at least allowed Stephen Fry to end his version of the Inspector on a note of dignity.}

The Eighth Inspector's books, which were more tightly written and not subject to horrible theatrics, are notably better. Likewise, his audio plays, which often poked fun at his short run as the Inspector, received wide acclaim for his writing, especially the tragic "Bright Eyes". The Inspector's primary Associate in the later books and broadcasts was Fitzwilliam Fort, an [[AmateurSleuth amateur detective]].

* InspectorOblivious: Fans complained about this comic typecasting for Carell in the TV movie, but in his later adventures, this is revealed as a [[ObfuscatingStupidity cunning ruse]].
* OohMeAccentsSlipping / NotEvenBotheringWithTheAccent: Another source of fan complaints. Carell only attempted an English accent during the first fifteen minutes of the movie; afterward, he spoke in his natural accent and would [[LampshadeHanging turn to the camera and wink]] whenever he said something British like "lorry" or "packet of crisps".

!!The Unknown Inspector (a.k.a. the Undercover Inspector)
This divergent incarnation of the Inspector was played by Creator/WilliamHurt.

As revealed in the [[MilestoneCelebration 50th anniversary special]], the Infinity Knight High Command assigned the Inspector to [[TheInfiltration go undercover]] as a [[CowboyCop rogue cop]] to investigate [[DirtyCop renegade fellow space-time officers]] who were conducting their own private war against the Blorgons. The Eighth Inspector secretly adopted the identity of the Unknown Inspector with the special assistance of the [[WizardsFromOuterSpace mystic Teman Mothers]], who transform him in a different version of the standard Kayaclaschian metamorphosis. What he did not suspect was that his inquiries would lead into the Time Wave...

* AwfulTruth: He's the one blamed for the final catastrophe in the Time Wave, and the Inspector subsequently disavowed this incarnation entirely.
* FedoraOfAsskicking: Doubles as a ShoutOut to the NiceHat worn by Christopher Lee's early non-canonical Inspector Spacetime character in the 1964 and 1965 films.
* ZeroApprovalGambit: The only way to prevent history from remembering the Infinity Knights as having been as bad as the Blorgons, if not worse, was for him to obliterate both sides with a [[SwirlyEnergyThingy trans-temporal tourbillon]], even though this means his TakingTheHeat for the Time Wave.

!!The Ninth Inspector
The ninth Inspector was played by Mark Williams.

Mark Williams revived the Inspector with sad humor and a genuine presence. Unfortunately, his obligations to the Film/HarryPotter franchise cut his tenure to only one season. Williams also played the Inspector in a charity event with DanielRadcliffe as his associate. Many fans were upset to learn that the combination was for the charity special only; however, most forgave the writers when the first episode introduced a new associate, Lily Taylor.

The Ninth Inspector had a curious aversion to leather.

The Ninth Inspector also traveled with Rory Williams. Rory's role ended when he learned how to cheat death and had to lose all of his memories as a consequence. Darvill would go on to play the exact same character on that Ripoff, with memory loss and cheating death skills fully intact.

* TheDandy: This Inspector's ridiculously posh outfits, even more so than the Second, often drifted into this territory.
* SkewedPriorities: The first thing he did after his metamorphosis completed and the BOOTH started ''crashing to Earth''? Barge straight toward the dressing room to change out of his drab pajamas.
* TheStoic: As a result of being LastOfHisKind, the Ninth Inspector became more and more detached, adopting a "stiff upper lip" persona that he'd maintain even in the most dire of situations.

!!The Tenth Inspector
The tenth Inspector was played by Daniel Landlord (later credited under his given name, Christopher Obi).

Landlord played the first black Inspector in the series. Landlord was a virtual unknown when cast, but some fans consider him the best of the recent Inspectors.

The Tenth Inspector is known for his coke-bottle glasses, endless string of bizarre and humorous shirts, and strong character growth. The Tenth Inspector is also bookended by two of the favoured Associates—Lily and the Constable.

* {{Adorkable}}: By far the geekiest of all the Inspectors.
* SpecsOfAwesome: WordOfGod states it is a ShoutOut to the First Inspector.

!!The Eleventh Inspector
The Eleventh Inspector was played by Travis Richey.

Richey is most known for being the Inspector chosen to feature in the short clip in the TV show ''Community''. The clip, from early in his run while he still traveled with the Constable, is credited with truly reviving the fandom.

The Eleventh Inspector is known for his bowler hats.

The Eleventh Inspector traveled with the Constable and later with a young couple, Angie Lake and Aidan Davies. Brooke Rhapsody, a puzzle shrouded with mystery, was also part of his life. His time was marked by an increasing popularity among the denizens of the universe that can cause problems when he needs to save the day and simply ''doesn't have time'' for all the autographs. His associates were known to be kidnapped just so that the abductors get a chance to meet him, causing the Eleventh Inspector to start seriously questioning whether he should just make his associates wear a bell.

* HeroicSelfDeprecation: Hit a very low point in his last season where he decided he wanted a metamorphosis as soon as possible, after his whole world just fell apart and his past selves [[DarkestHour did nothing to stop the catastrophe]]. [[spoiler: He went out overjoyed to be changing into a new body.]]
* IconicOutfit: Bowler hats, to the point that it is nearly a symbol of the show.
* TookALevelInJerkass / TookALevelInKindness: After his awful final encounter with the Snarling Lions, he "[[AchillesInHisTent took a leave of absence]]" for a while, donned darker clothes, and became a bit allergic to social interaction. But he grew out of it, save a few [[BerserkButton chronic fits of anger]] whenever his lost companions were [[MyGreatestFailure brought up]] [[RunningGag in conversation]].

!!The Twelfth Inspector
The current incarnation of the Inspector is played by ██████████.[[note]]Since everyone has their own idea of who would be perfect as the Inspector, the casting is explicitly left open to tropers to imagine whomever the wish.[[/note]]

[[folder:Associates and Supporting Cast]]
!!The Model X7 Dimensioniser Time Booth.
* CargoShip: Some fans continue to ship the X7. with the Inspector, although all writers have been quite staunch in the fact that this is ridiculous, [[WordOfGod and has no basis in canon]].
* ModeLock: Has been stuck in its present form ever since landing in the Sprint Street Phone Box Manufacturing Works in the very first episode.
* StarFishAlien

!!Classic Associates
!!!Susannah Overseer (First Inspector)
->Played by Honor Blackman in the series and Maureen O'Brien in the radio plays
* EarlyInstallmentWeirdness
* FrenchMaid: Introduced as the Inspector's maid in an attempt to explain [[InnocentCohabitation why a young(er) girl like her is living with him]]. Not actually French, though.
!!!Irma Rong and Bart Gilbert (First Inspector)
->Played by Joan Plowright and Jeremy Brett
* JumpedAtTheCall
* SlapSlapKiss - VitriolicBestBuds: Their relationship falls somewhere in this spectrum. Towards the end of their run, [[spoiler: it started shading more into SickeninglySweethearts, and they get married in their final episode.]]
!!!Layla (First Inspector)
->Played by Bernadette O'Farrell
* TheFutureIsShocking: Layla found it difficult to reconcile her CodeOfHonour with modern concepts of law and order.
* HeroicSacrifice: Halfway through "The Blorgon's Cunning Scheme".
* JeanneDArchetype: Although in this case, she's an ''English'' LadyOfWar from the [[DarkAgeEurope Dark Ages]].
* WeHardlyKnewYe: The first Associate to show how AnyoneCanDie in the programme.
!!!Officer Tara Parradyce (First Inspector)
->Played by Suzan Farmer
* ActionGirl: At the beginning of epic twelve-episode serial "The Blorgon's Cunning Scheme", she introduces herself as a SpacePolice agent.
* CombatPragmatist: Tara uses [[ImprovisedWeapon improvised weapons]] and [[TryingToCatchMeFightingDirty various dirty tricks]] over the course of her appearance.
** After Layla sees Tara zap a Blorgon InTheBack.
-->'''Layla''': You fight without honour!\\
'''Tara''': I fight with a ''RayGun''.
* [[spoiler: DarkActionGirl]]: What she turns into over the course of "The Blorgon's Cunning Scheme".
* FutureSpandex: Epitomized by her SpaceClothes version of the SpyCatsuit.
* [[spoiler: ZeroApprovalGambit]]: What turns out to have been her plan all along at the end of "The Blorgon's Cunning Scheme" (hence her ultimate unsuitability as a continuing Associate).
!!!Nicola "Coco" Coates (First Inspector)
->Played by Anna Quayle
* AmericanAccents: Famously invoked with her Chicagoese accent and then [[NotEvenBotheringWithTheAccent revoked]] by BTV following audience complaints her character was impossible to understand.
* CuteAndPsycho: Heavily implied this [[TheDitz kooky bohemian]] in a DangerouslyShortSkirt is related to [[TheFlapper the flapper]]-[[DamnItFeelsGoodToBeAGangster gun moll]] the Inspector encountered decades earlier in "[[TheRoaringTwenties The St. Valentine's Day Massacre]]".
* PluckyGirl: Ready to stand up anyone and anything, from the outlaw Gunslinger Frank James to the [[KillerRobot M7 Peacemaker automata]].
* PutOnABus: Literally. She and the Inspector tearfully part company at Victoria Coach Station at the beginning of "The Opium Dealers".
* RealLifeWritesThePlot: Quayle had requested her character's departure in "The Peacemakers" at the end of Season 3 when she learned that Leslie French would be leaving (and the imposing Christopher Lee would be his replacement), but producers convinced her to come back at the beginning of Season 4 so her character could receive a proper farewell.
!!!Peter/Petula (First and Second Inspectors)
!!!Aiden (Second Inspector)
->Played by Hamish Wilson
* CoolSword: Never seen without his high-tech claymore.
* NoodleIncident: Born in [[{{Oireland}} Scotland]] of the far-distant future; most of what little the audience learns about that place and time came from the comments he would occasionally drop. ("Course I know what an elephant is. The wretched beasts came blundering around every time they opened the Sgian-dubh Gate.")
!!!Regina Ayrefield (Second Inspector)
->Played by Susan Hampshire
* CatchPhrase: Although Regina is nobody's ScreamingWoman, she would loudly exclaim "How quite extraordinary!" when encountering the aforementioned MonsterOfTheWeek.
* FishOutOfTemporalWater: Not even the novels of her beloved [[Creator/HGWells Herbert Wells]] could prepare her for travelling with the Inspector.
* SilkHidingSteel: While the Edwardian Suffragette received a [[ProperLady proper upper-class upbringing]], she is eminently capable of defending herself against the MonsterOfTheWeek.
* WideEyedIdealist: Unfortunately, the future [[TheFutureIsShocking does not hold up]] to her rather utopian ideals, so at the end of "Rage of the Depths", she decides to return to her own era to improve things there.
!!!Constable Rosamund (WPC Rosamund Murray of Exo-Pol) (Second Inspector)
->Played by Anna Massey
* MarriedToTheJob: Aiden's attempts to flirt with her while she's assisting with the investigation in "The Underground of Doom" receive only silence.
* TheSilentBob: Although she has only three lines ("How d'you, Inspector.", "Look out, Inspector!", and "Good-bye, Inspector"), Massey's reactions to the Inspector and the Superintendent did more with a blink, an eye-roll, and a raised eyebrow than volumes of dialogue.
* SuspiciouslySimilarSubstitute: To Susannah Overseer, to a certain extent for a human.
* WeHardlyKnewYe: Her stoically stepping up for a SuicideMission against the Magma Men planning a volcanic eruption at the Piccadilly Circus station is a TearJerker.
!!!Joey Eliot
->Played by Suzanna Leigh
* BadassUnintentional: Lived a relatively normal life until the Inspector popped in to offer her the opportunity to unravel the mysteries of the universe and save planets.
* HairOfGoldHeartofGold: Probably the kindest of all the Inspector's associates.
* MsFanservice: Known for her costume's plunging necklines.
* UnfazedEveryman: Becomes this after a few adventures.
!!!Elisabeth "Bess" Wilde, M.D. (Third Inspector)
->Played by Virginia Maskell
* AloofDarkHairedGirl: While the Third Inspector's post-metamorphosis hypochondria could be exasperating, Dr. Wilde's bedside manner was pretty frosty in general.
* InformedAbility: Although the Inspector often talks up Bess's preeminence as a physician back in 20th-century Oxford, she [[ThePiratesWhoDontDoAnything never offers a medical opinion]].
* ThouShaltNotKill: With her adherance to the Hippocratic Oath, Bess is an ActualPacifist compared to the Inspector's [[TechnicalPacifist technical one]].
** This was used as the rationale for [[PutOnABus her departure]] between seasons seven and eight.
!!!Yosif (Third Inspector)
->Played by Lucy Fleming
* BrilliantButLazy
* SamusIsAGirl
* WholesomeCrossdresser
* ACupAngst: Only mentioned briefly, but the time she was teased about it by Markus Rogen was one of the few occasions she was genuinely hurt.
!!!Markus Rogen (Third Inspector)
* JerkWithAHeartOfGold
!!!Superintendent Irvine Leith, London Branch, Exo-Pol (Third and Fourth Inspectors)
->Played by Norman Bird
* [[{{DaChief}} The Superintendent]]: TropeNamer
* OldFashionedCopper
* ReasonableAuthorityFigure: At least at first.
* [[ImmuneToBullets Insusceptible to Handcuffs]]: The bane of his career.
!!!Mary Sue Brown (Third and Fourth Inspectors)
->Played by Susannah York
* {{AnythingThatMoves}}/{{BiTheWay}}: Part of the reason her spin-off is considered DarkerAndEdgier than its parent show.
* EnsembleDarkhorse: Popular enough that she gained her own highly rated spin-off, entitled ''The Mary Sue Predicaments''.
* IntrepidReporter: A talented photojournalist who took her skills as a celebrity tabloid reporter to fighting monsters.
!!!DI Gary Mulligan (Fourth Inspector)
->Played by Lewis Collins
* AmericanAccents: Noo Yawk by way of Chicawgo.
* NewYorkCityCops: Mulligan was seconded to Exo-Pol from the NYPD.
* OddCouple: He's a CowboyCop from the [[{{Eagleland}} U.S. of A.]], he's an earthbound alien detective--TheyFightCrime!
* OldShame: Collins had to live down this character (and [[IWasQuiteAFashionVictim his wardrobe]]) when he followed producer Brian Clemens to ''Series/TheProfessionals'', in which he played the [[BloodKnight hard-bitten]] CI5 investigator Bodie.
* TheSeventies: Gary wore his sideburns long, his ties wide, his trousers flared, and his polyester suits in earth tones. [[JiveTurkey Can you dig it?]]
* TheyKnewTheRisks: His epitaph on [[TakingYouWithMe his mutually fatal fight]] with his [[RobotMe mechanical duplicate]] in "The Robot Revolution", capping his TragicBromance with the Inspector.
!!!Reena (Fourth Inspector)
->Played by Imogen Hassall
* ActionGirl: With an affinity for whips.
* [[spoiler: [[DroppedABridgeOnHim Dropped A Bridge On Her]]]]: Possibly. [[spoiler: The last the viewer sees of her, she's just been literally stabbed in the back; whether she actually died from the wound has never been explicitly revealed in-show.]]
* JunglePrincess: Literally. In her final episode [[spoiler: she was crowned Queen of Barbartron IV]] following [[spoiler: her father's HeroicSacrifice.]]
!!! FE-Line (Fourth Inspector)
* DoAnythingRobot
* FemaleFelineMaleMutt
* NonHumanSideKick: A robot cat.
!!!Infinity Knight Lunda (Fourth Inspector)
->Played by Cassie [=McFarlane=], Josette Simon, and Grace Jones
* InsistentTerminology: Lunda was an Infinity ''Knight'', ''not'' an "Infinity Dame."
* KnightTemplar: Willing to do whatever it took, including (see below) dying a couple of times, finally [[spoiler: taking the Bolt in Space on a one-way trip ''out'' of Space, into another dimension, to keep it away from the Orange Warden forever.]]
* SuspiciouslySimilarSubstitute: A rare in-universe example: She metamorphosed twice while on the show (''everybody'' kept dying around the Fourth Inspector...); and, very much unlike the Inspector's various incarnations, all three times was played by similar-looking actresses who portrayed the role in much the same manner. This provoked both a million fan-theories about male/female Infinity Knight biology ''and'' many complaints of UnfortunateImplications, especially since along with being tall and thin, all three actresses were [[BlackDudeDiesFirst black]].
!!!Veneziana (Fourth and Fifth Inspectors)
->Played by Pauline Quirke
* ActionGirl / FauxActionGirl: Drifts back and forth between these two. She ''is'' good with a lasso, but she's not quite as tough as she looks or pretends.
* AmericansAreCowboys: Or at least their 24th century descendants are. Always wears a bushranger hat and carries a lasso. She did eventually ditch the spurs.
* FanPreferredCouple: She and Thorough and that lasso spawned a thousand {{FanFic}}s, even though there was never a hint of official on-screen attraction between them.
* NiceHat: Never seen without it.
* OohMeAccentsSlipping: Considering the accent they came up with for the character to sport, it's surprising this didn't happen more often.
* OverlyLongName: So long the viewer never even hears all of it: "Veneziana Lopez Kelly Gab... Heck, mates, just call me Veneziana."
* RunningGag: Afraid of horses, and so constantly has to deal with them.
-->"Someday, we're gonna crack open the door to that X7 and there's gonna be a goldurn ''horse'' crammed inside."
* [[WhyDidItHaveToBeSnakes Why Did It Have to Be Horses?]]
!!!Thorough Visor (Fourth and Fifth Inspectors)
->Played by Hugh Laurie
* [[RecycledInSpace Bertie Wooster IN SPACE!]]: Though Laurie didn't ''officially'' [[Series/JeevesAndWooster play Bertie]] until after his stint on IS.
* BunnyEarsLawyer
* FanService: wore very short shorts.
* HiddenDepths
* HumanAllAlong: It seems at first he's an alien, but it's eventually revealed that he's [[spoiler: a 20th-century human from a very eccentric family.]]
* NiceGuy
* TheWoobie
!!!Nymeria of Planet Kraken V (Fifth Inspector)
->Played by Karen Dotrice
* InsistentTerminology: She is a "Krakenite", not a "Human".
* TheMedic
* TheOjou
* PstandardPsychicPstance
* PsychicPowers
* PsychicStrangle: Very much to her horror, she learns she can do this.
* SpoiledSweet: Due to her aristocratic background.
* LadyOfWar: Thanks to CharacterDevelopment
!!!Mimmek (Fifth Inspector)
* ChuckCunninghamSyndrome
* CowardlySidekick: Mimmek quickly became such a NervousWreck while adventuring with the Inspector that he retreated to the Booth at the end of "The Slumbering" (and according to WordOfGod has never emerged).
* PunnyName: Averted. Preliminary SpecialEffectsFailure required his extraterrestrial ability to be hastily rewritten from mimicry to invisibility.
!!!Jeffrey (Sixth Inspector)
->Played by Creator/RikMayall
* AlasPoorScrappy: Only Jeffrey's tragic death saved him from the fans' extreme hatred of him.
* ButtMonkey
* OohMeAccentsSlipping: Mayall's attempt to play Jeffrey as an ordinary American [[DawsonCasting teenager]] resulted in his pronunciation vacillating between [[{{Joisey}} New Jersey]] and [[FlyoverCountry the entire Midwest]].
!!!Benjamin (Sixth Inspector)
* ForgottenFallenFriend: Seriously, who ever remembers Benjamin?
!!!Theodora "Dynamo" [=McRae=] (Seventh Inspector)
->Played by Creator/TraceyUllman
* ActionGirl: Attacked a Blorgon with a hockey stick. ''Yeah''.
* DawsonCasting: She's a teenager. [[SarcasmMode Yeah]].
** Turned into a TakeThatCritics with her appearance in the TV Movie, in which she plays the character under old-age makeup.
* HormoneAddledTeenager
* MoreDakka: Her answer to most problems.
* StrawFeminist: Thanks to the era's lackluster scripts, she sometimes edged into this territory.
* StuffBlowingUp: Would compulsively leave dynamite in buildings to have this affect. Joined up with the Inspector after almost doing as much to the X7.
!!!Charity Galloway (Eighth Inspector)
->Played by Anne Hathaway
* CloudCuckooLander
* DawsonCasting: Averted. As the [[ItRunsInTheFamily Eighth Inspector's niece]], Anne Hathaway was playing a character her apparent age.

!!ExpandedUniverse Associates
!!!Fitzwilliam Fort (Eighth Inspector)
* AddedAlliterativeAppeal: "Fitzwilliam Fort, fearless finder of freakish phenomena."
* AmateurSleuth
* BadassLongcoat
* CelibateHero: As he puts it, "I've got plenty of problems, but a dame ain't one."
* HardboiledDetective: He acts like one, but he's eventually forced to admit he's not a real private investigator and never was.
* NiceHat: A fedora. At least, he thinks it's nice, despite people telling him it's cliche and a bit naff.
* PrivateEyeMonologue: The books he narrates are written in this style. He has a bad habit of narrating aloud to himself as well.
* TalksLikeASimile
* {{Theremin}}: He plays one in the books, but ironically, it never comes up in the audio plays.
!!!Georgina "George" Liddell (Eighth Inspector)
* BreakTheCutie: She starts out sweet and naive, but she gets her best friend fired from his job on her first day and things just go downhill from there, until she's trapped in the mind-bending [[EldritchLocation Peculiar Dimension]], neck-deep in evil cattle, fending off Infinity Knights who want to kill her for being a walking paradox with one hand and [[BodyHorror disgustingly fused]] to the Inspector by the other.
* MacGuffinGirl: A few {{Well Intentioned Extremist}}s have attempted to take advantage of her nature as a walking StableTimeLoop to achieve their ends, such as altering causality to make it impossible to go back in time and do something as icky as becoming your own aunt.
* MindScrew: How she became her own aunt.
* [[MyOwnGrampa My Own Aunt]]: Leading to all sorts of drama with the Infinity Knights, who think it's kind of weird and gross.
* TemporalParadox: Went back in time and accidentally became her own aunt.
!!!Mmm'Fash't'ஐ'lan'zac (Eighth Inspector)
* BewareTheNiceOnes: [[spoiler:Eventually revealed to have murdered an entire ''dimension''. But it was just the Peculiar Dimension, with no space, only time, and no one liked it anyway.]]
* CoconutSuperpowers: A shapeshifter who prefers the form of a parrot, which is probably the reason he's restricted to audio plays. Subject to a lot of LeaningOnTheFourthWall, wherein he uses his powers to become invisible and asks the Inspector to check whether he can see him; the Inspector replies in a pointed tone, "I'm pretty sure ''nobody'' can see you."
* MagicPants: Averted; probably the other reason he's audio-only.
* MyNaymeIs: It's pronounced "Chris".
* PunctuationShaker
* VoluntaryShapeshifting
!!!Jimmy [=McSporran=] (Eighth Inspector}
* ExpandedUniverse: Fort, [=McSporran=], Liddell, and Mmm'Fash't'ஐ'lan'zac have never appeared on the actual show but have proved popular in various radio dramas and novels.

!!New Associates
!!!Rory Williams (Ninth Inspector)
->Played by Arthur Darvill
* AncientGrome: In regards to the [[Series/DoctorWho ''other'']] show. He spent a brief stretch of time posing as a Greek Demi-God in on the show; the other one tried to play homage to this but got the nationality wrong, making him Roman.
* BadAss: Considered one of the most epic associates to date, often completely upstaging the Inspector. Enemies often exploded when he came on screen.
* CombatMedic
* {{Immortality}}: The story of his inability to die needs no repeating here.
* LaserGuidedAmnesia: At the end of his tenure, he lost his memories. The actor, however, was not ready to give up the role and continued it on that ''other'' show, hoping to improve upon its quality.
!!!Lily Taylor (Ninth and Tenth Inspector)
->Played by Hannah Spearritt
* [[spoiler:AscendToAHigherPlaneOfExistence: Her ultimate choice. After her brief time as the Good Lamb, in which she personally saves countless billions of lives from the Blorgons, the Immortals offer Lily a seat in their [[FantasyPantheon pantheon]]. Lily spends her remaining time on the show debating this, before ultimately choosing to accept her destiny as the Good Lamb and ascending to watch over the universe with the Immortals.]]
* AudienceSurrogate
* BareYourMidriff: In a metallic silver tanktop.
* HairOfGoldHeartOfGold
* IWantMyBelovedToBeHappy: Part of her reasons for leaving Minnie: She felt she wasn't good enough for her.
* LipstickLesbian: Although she was hinted to be bisexual.
* MsFanservice
!!!Minnie Smythe (Ninth and Tenth Inspectors)
* NaiveEverygirl
* AlwaysSecondBest: She is always being compared to Lily by the Inspector.
* AscendedExtra: Originally only appeared in the episode "Lily" as the girlfriend that Lily leaves behind but was eventually picked up as an Associate by the Tenth Inspector.
* DeadpanSnarker: At times.
* LovableNerd
* PairTheSpares: With Joanna.
* TookALevelInBadass: Over the course of her travels with the Inspector. She faced the Circuit-Chaps single-handedly to save the Inspector and Joanna, for crying out loud!
!!!Captain James Haggard (Ninth and Tenth Inspectors)
->Played by Jamie Bamber
* AllergicToLove
* ArmouredClosetGay
* CerebusRetcon: His shyness in romantic situations and closet gayness is initially PlayedForLaughs, but it's later revealed that it's been a major source of distress for him for as long as he can remember (which admittedly isn't long, due to his endlessly-mysterious amnesia).
* ChasteHero: He's embarrassed by or oblivious to to flirting or innuendo of any sort. It's eventually revealed that this is partially caused by the fact he's ashamed of his sexuality.
* ChivalrousPervert: Easily-flustered and sexually conservative, initially.
* ComingOutStory
* {{Gayngst}}: Went through deep emotional trauma due to his inability to accept his pansexuality.
* HaveIMentionedIAmHeterosexualToday: Lily eventually gets fed up with his repeated insistence that he's straight and suggests that he prove it by kissing her.
-->"No, sorry, I -- not that you're not a pretty girl -- or I'm not straight, or anything -- oh, look, is that a Blorgon? Thank goodness!"
* TouchedByVorlons: Given the gift of immortality by the [[spoiler: Good Lamb's enveloping wool]].
* WhoWantsToLiveForever: Almost entirely averted. Haggard's immortality is of the no-drawbacks kind, and he remains very cheerful about this aspect of his condition.
!!!Yorke (Tenth Inspector)
->Played by Creator/TomHardy
* AlwaysChaoticEvil: He is a Time Deviant, after all.
!!!Mona Virtue (Tenth Inspector)
* CatchPhrase: Commonly called the Inspector and other aliens "Time Dude"!
* FieryRedHead: Averted. One of the most quiet and demure associates on the show.
* MindRape: Some consider her eventual fate this.
* ShrinkingViolet
!!!Joanna Martin (Tenth and Eleventh Inspectors)
->Played by Georgia Taylor
* AllLoveIsUnrequited
* BiTheWay: After spending her entire tenure pining after the Inspector, she was suddenly revealed to be bi so she could be in a relationship with Minnie.
* BunnyEarsLawyer: Spent most of her first episode annoying the Inspector by constantly introducing herself, complimenting his shirt, then going up behind him and repeating the process. Won the Inspector over by successfully arguing that taking the travel agency to Mars—while amusing—was in fact illegal and getting them all returned safely.
* ClingyJealousGirl: Her eyes turn green every time Lily is mentioned.
* DoesNotLikeShoes: In "Fry and Laurie", everyone has to go barefoot at the solar medical facility due to extremely prejudiced sanitation rules. Joanna, however, is ''very'' happy to run around in her bare feet due to her [[EarthyBarefootCharacter country roots]], bellowing "Shoeless by the Sun!" while wiggling her toes in the astroturf.
** She actually leaves the facility still barefooted and the Inspector has to go back and pick up her shoes, accidentally going back too far in time and handing them off to her before they officially met, creating a StableTimeLoop. After the Inspector shows her inside the Booth and mentions the astroturf room of his own, Joanna just kicks her shoes off again and tries to explore the time machine barefoot... only to find herself reaching for her shoes in a heartbeat when she sees there's no rooms at all but the one space. Turns out the Inspector tricked her to curb that habit.
* PairTheSpares: With Minnie.
* SuddenlySexuality
!!!Constable Wigglesworth (Tenth and Eleventh Inspectors)
->Played by Derwin Jordan
* BadAssNormal
* HeartBrokenBadass
* HoYay: Yeah you just conscripted a team of Scum and your Ex to wage war on the Overseers of Casualty cause the Inspector is [[SarcasmMode just a very good friend.]]
* StrangledByTheRedString: The fans [[{{BaseBreaker}} view his relationship with Camilla Sea as one.]]
!!!Camilla Sea (Tenth Inspector)
* AbortedArc: Her character had a bigger arc planned but the actress got a better offer abroad.
* BaseBreaker: Either viewed as the ''other'' feisty red head who brought spirit and romance to Wigglesworth's life. Or the over dramatic redhead who also [[spoiler: went bad.]]
* HeroicSacrifice: Absorbed the Time Deviant strain to save the Inspector. It did not end well for her...
* PutOnABus: Due to her joining the cast of the [[Series/StargateUniverse WormHole Extreme: Starship Horizon]] as plucky Scottish medic Melody Mcallister Scott, she was brought back only once after [[spoiler: being turned into a Time Deviant.]]
!!!Angelica "Angie" Lake (Tenth and Eleventh Inspector)
* FieryRedHead: Very much so. Literally, in the episode "See No Evil".
* HeelFaceTurn: Started travelling with the Sergeant due to a series of misunderstandings, but eventually switched to the Inspector's side.
* JustFriends: Towards Rory.
* MyFutureSelfAndMe: Angie: "Well kiddies, things took a turn for the strange."
* SlapSlapKiss: With Aiden.
* VictoriousChildhoodFriend: Again with Rory. Although that didn't work out so well.
!!!Aidan Davies (Eleventh Inspector)
->Played by Andrew Lee Potts
* OneSteveLimit: Averted, with the Second Inspector's associate of the same name. ("You're not Aiden! [[ContinuityNod Aiden had a sword]]!")
* SlapSlapKiss; With Angie.
!!!Brooke Rhapsody (Eleventh Inspector)
->Played by Creator/CareyMulligan
* ActionGirl: Armed with her laser blaster and hallucinogenic nail polish.
* CareerVersusMan: Completely averted, thank the dimensional vortex!

* HotScientist[[{{Adventure Archaeologist}} Adventure Paleontologist]]: Brooke has a career as a paleontologist.
* WalkingSpoiler: Her presence in the series is part of a huge plot twist [[spoiler:that you have to watch the show to understand]].
* WeaponOfChoice: Her big hammer, laser blaster, and nail polish.

!!!Geneva Stilton (Eleventh and Twelfth Inspectors)
->Played by Alison Brie
* ArbitrarySkepticism: For someone so GenreSavvy, she often has difficulty believing her adventures with the Inspector are really happening.
* InSeriesNickname: Referred to as "the Improbable Woman" by the Inspector for her uncanny ability to [[NoOneCouldSurviveThat escape death by the narrowest margins]] on a regular basis.

!!Special Episode Associates
!!!Maura Dewitt
->Played by LilyAllen
* {{Meganekko}}
!!!Robbie [=McMillan=]
!!!Othbo Perth

!!The Blorgons (a.k.a. Blogons)
These robots (although they're occasionally called cyborgs) first appeared in 1962's "The Blorgons", having been created by Vosrda to commit [[ArsonMurderAndJaywalking armed robbery, burglary, and criminal mischief]] on his behalf. They would eventually become the Inspector's most iconic enemy.
* ArtEvolution: The Blorgons benefited greatly from the new series' increased budget. You can barely see the duct tape ''at all'' these days.
* {{Catchphrase}}: "ERADICATE!"
* [[SpellMyNameWithAnS Spell My Name with an R]]: Following initial confusion over the pronunciation of their name, the fanbase is divided on the spelling of "Blo(r)gon," and BTV seems to have changed their official stance multiple times during the show's run—one official episode guide even referred to the race as the "Blorgrons," the "Blogrons," and the "Blogrolls" ''on the same page.'' Needless to say, this isn't a controversy that'll end any time soon: Although a majority of fans seem to favour "Blogon" at present, the programme officially calls them "Blorgons".

!!The Digifleet of the Circuit-Chaps (also known as the Kybermenschen)
* CreepyMonotone: Subverted in "The Lost Asteroid" when the Inspector first attempts to communicate with the Digifleet in an imitation robotic accent, and the Circuit-Chaps counter with a characteristically chipper comeback.
* DissonantSerenity: The Circuit-Chaps are always in infamously high spirits, even when they're plotting the destruction of all organic life.
* DoAndroidsDream: The eerie question surrounding the Kybermenschen is whether they actually possess the mechanical equivalent of emotions or are merely simulating them to put their opponents off balance.
* TurnedAgainstTheirMasters: In "The Retirement Home of the Circuit-Chaps", the Inspector learns about the Second Industrial Revolution on their home planet that led to their ascendance.
* WeaksauceWeakness: In early serials the Circuit-Chaps were completely invulnerable to everything except lead particles, which clogged up their condensers and caused them to overheat. This worked well for a while, but as the series wore on the weakness was exaggerated to the point where anything even ''related'' to lead—lead bullets, lead plumbing, lead paint, lead pencils, etc.—would make them [[YourHeadAsplode explode]].
** This was fixed in the new series by their creators who state that "early prototypes reacted badly to the lead soldering on their circuitboards, but using ''gold'' instead solved that problem immediately."
* YouWillBeAssimilated: "You will be modified," the Circuit-Chaps reassure ordinary appliances and everyday gadgets before turning them into cheerfully murderous conscripts of the Digifleet.

!!The Sergeant
->First played by VincentPrice in the classic series, later by Windsor Davies and Peter Wyngarde, and then by Creator/ChristianSlater and Creator/StephenColbert in the TV movie; and by JulianSands in the new series
* AffablyEvil: Treats his rivalry with the Inspector as a friendly competition.
* BeardOfEvil: His infamous moustache. Subverted when he shaved it upon his sixth rejuvenation, much to the Inspector's shock.
* BlondeGuysAreEvil: When played by JulianSands in Series Three.
* DepravedHomosexual: [[UnfortunateImplications Controversially]] suggested by his unhealthy marriage to a Mexican shoeshine boy in the new series.
* DirtyCop: Although he is no longer associated with any police force, he still occasionally wears a police uniform and often uses police slang.
* EarlyInstallmentWeirdness: First introduced as the Postmaster in "The Crime Sports" (debatably).
* EyePatchOfPower: Gained one after the KnifeFight with the Inspector in Series Four.

!!The Instructor
->Played by Eleanor Bron
* AntiVillain: As her name suggests, this Infinity Knight set out to literally "educate the dear Inspector" rather than commit any outright villainy. The program was always very coy about whether she took this task upon herself, or was carrying out Infinity Knight orders with enthusiasm.
* ObfuscatingDisability: A borderline example, in that she always wore dark glasses and carried a white cane, but never explicitly tried to pass herself off as being blind.

!!Oscar del Manhattan
A CorruptCorporateExecutive with a collection of artefacts from across time and space, which he kept atop his skyscraper in [[VivaLasVegas Las Vegas]], Nevada, including a heavily damaged Blorgon.
* BigBad: Revealed to be behind the season's ArcWords- "The Stars are Vanishing". As detailed below, he was adding them to his collection.
* CorruptCorporateExecutive
* DeathByMaterialism: Was killed when he couldn't reach the X7 while his museum was collapsing, due to trying to carry so many of his artefacts at once. Though the Inspector tried to save him, del Manhattan just kept trying to grab one more artefact and trying to pick up the ones he dropped, forcing the Inspector to leave him behind.
* {{Greed}}: As detailed to the Inspector, del Manhattan literally wanted to rip the stars from the sky, label them, and stick them in a lovely glass case for all the world to see and marvel at.
* IWantSong: Has one of the few [[VillainSong Villain Songs]] in IS history.

->Played by Robert Helpmann
* EvilCripple: Following a near-lethal dose of radiation, Vosrda replaced the entire top half of his body with Blorgon cybernetics. The sight of his terrifyingly spindly little legs struggling under the weight of a robotic pepper shaker has driven many a child behind the sofa.
* MadScientist: Well, he DID create the Blorgons, and he DID try to kill everyone with them.
** Eventually becomes an EmperorScientist, somewhat against his will.

!! Ms. Patch
-> Played by Creator/AngelaLansbury
An old lady who knits and drinks tea. She also wants to kill the Inspector and steal Brooke Rhapsody's powerful weapons. She is the leader of the Quiet Organization.
* BewareTheNiceOnes
* EyepatchOfPower
* Meaningful Name
* NeverMessWithGranny
* WhenEldersAttack

!! The Indictor
->Played by Geoffrey Palmer
A [[OneSceneWonder One-Arc Wonder]], the Indictor prosecuted the Inspector for dereliction of duty, evidence tampering, witness harassment, and falsifying statements before revealing that he ''was'' [[ItWasHisSled a form of incarnation of the Inspector]], created from the collected [[OrderVersusChaos Order]] in the Inspector's soul.
* BaseBreaker: Whether the Indictor is from the Inspector's [[TimeyWimeyBall personal]] future or past, as seen on this very wiki.
* FutureMeScaresMe: The Inspector is ''horrified'' at the idea of becoming (or having been!) the Indictor.
* ObviouslyEvil: Subverted. Despite his VillainousFashionSense, the Indictor is canonically [[CharacterAlignment Lawful Neutral]].
* OneSceneWonder: Adding up all of his time on screen from the single arc in which he appears, the Indictor spends no more than ''forty minutes'' onscreen in [[LongRunner the entire series]].
* VillainousFashionSense: Let us count the ways:
** ExcessiveEvilEyeshadow (GuyLiner subtrope)
** HighCollarOfDoom
** OminousOperaCape (Well, technically, his judicial robes)
** [[SensibleHeroesSkimpyVillains Sensible Heroes, Skimpy Villains]] ([[WhoWearsShortShorts Under his]] robes... pass the BrainBleach)

!!Commissioner Sassafrass
->Played by SeanConnery
An ancient and powerful Infinity Knight who's credited with establishing the first police department on Kayaclasch. Wielder of an artefact called the Truncheon of Sassafrass. Thought to have retired thousands of years ago, until the events of "The Last Minutes".
* LargeHam

-> Played by Nigel Cuthbertson
An enigmatic "Man-tiss" from Thallidium, and a prominent enemy of the Eleventh Inspector.
* ArchEnemy: Of the Eleventh Inspector.
* CatchPhrase: "Bow down before Thoraxis!"
* LargeHam
* MrFanservice: He's a very muscular WalkingShirtlessScene.

!!The Homene Awareness and the Clothons

!!The Oddities

!!The Sloughers

!!The Snarling Lions
An observer-effect-dependent species, the Lions only exist when they're being observed by other life-forms, vanishing as soon as you blink. Not that you'd dare [[SchmuckBait turn your back on]] a fearsome, ferocious-looking lion... [[FridgeBrilliance which is just what they want]]. They absorb quantum energy by brutally killing people who look them, or are even aware they exist.

!!The Rostraans

!!The Lirusians
A species of aliens who are due to move in once the humans have left the Earth. A kind race, quite open to peaceful relations with humans.

!!The Time Deviants
They look human and can blend in seamlessly with our society, but they're soulless psychopaths who feed off of chaos and destruction.

!! The Quiet Men
When you look at these aliens, they will cause you to remember meaningless things so you don't focus on them. If you do remember them, that means that they don't care if you remember or not...[[OhCrap because you'll be dead soon.]] They cannot shut up.

!!The Orange Warden. The Blue Warden.
->Played by [[Series/TheGoodies Graeme Garden and Tim Brooke-Taylor]], respectively
These two bring new meaning to the phrase "SufficientlyAdvancedAlien". Members of the Pantheon of Immortals (see below).
