!!The Guys Shot Up In Space

[[folder: Joel Robinson]]
->'''Played by''': Joel Hodgson

The original "guy shot up into space" and the creator of the robots. Joel was an employee at Gizmonic Institute, both a janitor and inventor. As part of Dr. Forrester's experiment, he was launched into space aboard the Satellite of Love and is forced to watch horrible movies. Joel has a rather laid-back personality, and as their creator, often acts as a father figure to the Bots. Halfway through Season 5, Joel escapes from the [=SoL=] and is replaced by Mike. Joel comes back for one episode later on, revealing that after his escape he settled down as the manager of a Hot Fish Shop in Osseo, Minnesota.
* TheAce: But only in the season 10 premiere, where he fixes the SOL in a few hours among other great things... poor Mike.
* {{Adorkable}}: Has his moments.
* BewareTheNiceOnes: He's usually laid-back and takes his captivity in stride, but if the Mads try to hurt his bots he will go full PapaWolf on them.
* CatchPhrase: "We got Movie Sign!"
* CharacterizationMarchesOn: Back in KTMA and season 1, Joel acted as a resentful creator to the Bots, instead of the TeamDad he was famous for.
* CloudCuckoolander: "I'm strange, which results in creativity!"
* DeadpanSnarker: Leans more towards Deadpan than Mike.
* DissonantSerenity: You would think being kidnapped and stranded in space would have ''some'' effect on him.
* TheEveryman: "There was a guy named Joel, not too different from you or me."
* EyesAlwaysShut: The "sleepy eyes" act is a trait carried over from Joel's previous projects.
* GadgeteerGenius: The RidiculouslyHumanRobots, as well as all of his other inventions.
* GeniusDitz: Not so much ditzy as he is aloof.
* GrayEyes: When they open.
* HiddenDepths: This guy invented four robots [[RidiculouslyHumanRobots capable of free will, love]], [[DoAndroidsDream dreaming]], [[UpToEleven catching illnesses]], and ''[[UpToEleven food allergies]]''.
* HilariouslyAbusiveChildhood: Possibly implied. Joel once said his parents once forced him to take a bath in the front yard.
* TheKirk (Original)
* TheMadHatter: He's quite aware of how quirky he is, but he says it "results in creativity!"
* MellowFellow: Joel is pretty laid back and he seldom gets upset. According to the KTMA Opening Theme lyrics, Joel's response to being shot into space and being forced to watch bad movies?
-->Joel says, "When you got lemons, you make lemonade."
* MotherlyScientist: Often ends up disciplining/comforting the robots that he built.
* NiceGuy: He's almost impossibly friendly, and very hard to push.
* NiceJobBreakingItHero: While neither Joel, Mike, nor Jonah have any ability to control when the movies start or stop, it's Joel's fault. The ExpositoryThemeSong of the earlier seasons notes that he used the parts that could have let him do so to construct the robots.
* NotSoStoic: When he does lose his cool, it's startling.
** During ''Film/AttackOfTheTheEyeCreatures'', Joel ends up apologizing for the the rest of the the male sex, and later, actually loses his cool, berating one character:
--->'''Joel''': ''[angry]'' You know what? You are ''one '''sick''' mamma-jamma''.
** And then his infamous rare outburst in ''[[Recap/MysteryScienceTheater3000S04E24ManosTheHandsOfFate Manos: The Hands of Fate]]'', after twenty seconds go by with nothing of any appreciable importance happening on screen.
--->'''Joel''': ...'''''DO''' SOMETHING!!!'' God!
** And shortly after admonishing the Bots for yelling at the endless rock climbing sequence from ''Film/LostContinent'': "Who are you? Where are we? ''Can we get a FRAME OF REFERENCE, please?!''"
* OnlySaneMan: Roughly.
* PutOnABus: Or Put on an Escape Pod, to be precise, in the ''Mitchell'' episode.
** TheBusCameBack: He shows up to repair the SOL in the ''Soultaker'' episode.
* RedOniBlueOni: They only met once, but he's the Blue to Mike's Red. [[{{Irony}} Which is the opposite of their jumpsuit colors]].
* ReedRichardsIsUseless: There was a host segment where Joel created two levers that could ''[[RealityWarper alter reality]]'', including but not limited to changing the opinions of people, the position of the Satellite, the lights, and the situation people are in. It never shows up or is mentioned ever again, and Joel only ever uses it to screw around instead of using it to escape the Satellite or anything.
* StockholmSyndrome: Compared to Mike. While Joel did make the odd attempt to escape, he was resigned to his position, which is why he built the 'bots in the first place.
* ShoutOut: His last name is one of these to [[Series/LostInSpace Will Robinson]]. Also to ''Literature/RobinsonCrusoe'', as he frequently mentions being marooned in space.
* StraightMan: To the Mads and the Bots, despite his own quirkiness.
* SuddenNameChange: In the KTMA season, Hodgson simply used his full real name for the character. The surname was changed to "Robinson" after the move to The Comedy Channel.
* TeamDad: Tends to treat the Bots more like his children or students than his creations, taking pride in their accomplishments, reeling them in when they go too far, and going to great lengths to perk them up when they're upset. The Bots, for all the grief they give him, seem to appreciate this.
* TheStoner: Only subtextually, but given a nod when one of his invention exchange items appears to be [[GettingCrapPastTheRadar basically a motorized bong]]. Otherwise this particular theory for why he's so gosh darn laid back and sleepy eyed all the time is only fanon.
* TookALevelInJerkass: During his return appearance in the ''Soultaker'' episode , Mike and the Bots ask him to take them back to Earth with him. He refuses, muttering, "Yeah, except I really don't ''want'' to..." before covering that he actually enjoyed his years on the SOL, and they made him a man, and tells Mike and the Bots that he doesn't want them to miss another minute of it.
** Also in ''Fire Maidens of Outer Space'', after the whole "Timmy" incident, he blames Crow despite being dismissive of this strange new being. Granted, it was Crow's fault, but still.
** PlayedForLaughs in a KTMA episode with Servo's diary entry, where Joel is portrayed smacking the Bots around and smoking a big cigar. Halfway through he says: "I'm not usually this cruel; it's just Servo's perception of things.

[[folder:Mike Nelson]]
->'''Played by''': Michael J. Nelson

The second "guy shot up in space" after Joel escaped from the Satellite of Love halfway through Season 5. Mike Nelson is a lifelong temp-worker, bouncing from job to job. Only the coincidence of him being temped out to Deep 13 for their audit at the time of Joel's escape led to him being employed long-term by Dr. Forrester. He's described by Dr. Forrester as a "disgustingly mild-mannered dope". To the bots, he's seen as a big brother, college roommate type, or amicable coworker, depending on the situation.
* AlternateHistory: Inspired by a time-traveling Crow's warnings, in one timeline he devoted himself to his rock band, Sex Factory, instead of temping. They actually got successful enough to open for {{Music/Motorhead}}, but Mike died due to head trauma from thrown hotel keys and his abusive JerkAss brother was sent into space instead.[[note]]Said brother thought Mike's demise was a DyingMomentOfAwesome.[[/note]] Crow had to go back again to avert this.
* AmbiguouslyGay: Or bi. In "Werewolf" he implies he dated a man named Steve who died (but is interrupted by the movie sign), and in "Laserblast" Crow pokes fun at him for thinking one of the actors is cute, among others. He once kissed a surly old truck farmer. (Who was a durned fine kisser.)
* BatmanCanBreatheInSpace: Common with the entire Sci-Fi cast. [[MST3KMantra Try not to think too hard about it.]]
* BewareTheNiceOnes: Mikey and the Llama comes to mind.
* BigBrotherInstinct: Towards the Bots... at times.
* BigScrewedUpFamily: His Jerkass brother Eddie is just the tip of the iceberg, not the least of which they have a tendency to marry lower primates (which causes ''Franchise/PlanetOfTheApes''.) His dad, Elmer "[[LifeOfTheParty Keg-drainer]]" Nelson is usually laid back, but can be quite the party animal, according to Crow.
* ButtMonkey: Tom and Crow have openly admitted to destroying his most prized possessions just ForTheLulz.
* CatchPhrase: "We got Movie Sign!" He has also said "Get him!" enough times to make it a minor catchphrase.
* CharacterDevelopment: In a sense. Though not a tech guy, he eventually learns how to make repairs and mild alterations to the Bots.
* CharacterTic: More likely the real Mike Nelson's habit, but Mike often unconsciously touches the bots and other props when it's usually not appropriate to.
* ContrastingSequelMainCharacter: He's more of an {{Everyman}} than Joel, a part time inventor. The bots [[NoRespectGuy tend to ignore or even outright bully him]] whereas they previously shared genuine camaraderie with Joel. He's also considerably more high-strung than the more relaxed an easygoing Joel. And he wears blue in contrast with Joel's red.
* DeadpanSnarker: Leans more towards Snarker than Joel.
* HypocriticalHumor: Makes fun of Robert Z'Dar's LanternJawOfJustice in "Future War", despite being an example of the trope himself.
* TheKirk (Replacement)
* TheKlutz: He's got a pretty big clumsy streak and often screws things up for himself.
* KubrickStare:
** [[http://www.youtube.com/watch?v=kiN6yLiif-M Mike doesn't think that's funny.]]
** Here's a [[http://i42.tinypic.com/2iitkww.jpg real doozy from Mike!]]
* LanternJawOfJustice: He has a rather hunky face.
* LimitedWardrobe: Apart from the jumpsuit, there's [[http://www.youtube.com/watch?v=HLk_B93Qo38 this]].
* MikeNelsonDestroyerOfWorlds: The TropeNamer. He destroyed three planets in the eighth season alone.
* NamesTheSame: [[invoked]] As Mike Nelson of ''[[http://www.imdb.com/title/tt0051311/combined Sea Hunt]]'' fame. However, it's never referenced til ''[[Recap/MysteryScienceTheater3000S09E09Gorgo Gorgo]]''. It's odd because the Lloyd Bridges phrase "By this time my lungs were aching for air" was an oft-used riff on the show.
* PhraseCatcher: "[[NiceJobBreakingItHero Good one, Nelson!]]"
* ThePigPen: The man can't stay tidy. Give him a tie, and a few seconds later, it'll be covered in food stains. No wonder at one point, he and the 'bots are living in their own filth.
* PowerBornOfMadness: Mike's tendency to [[SanitySlippage randomly assume the identities of other people]] ended up saving the crew's lives during the [[Film/{{Laserblast}} Season 7 finale]], when he transformed into [[Series/StarTrekVoyager Captain Janeway]] and rescued the satellite from a black hole via a stream of TechnoBabble. And again in Season 8, when turning into Adam Duritz scared away [[ItMakesSenseInContext the aliens attacking the ship]].
* RedOniBlueOni: The one time he met Joel, he came across as the Red to Joel's Blue.
* SanitySlippage: Many, many times. Mike isn't quite as coolheaded as Joel, whether it's thinking he's Carol Channing or Captain Janeway, climbing down a stepladder to try to escape the S.O.L.[[note]]Oddly, this one would have ''worked'' if Mike had remembered that [[WhatAnIdiot the S.O.L. was in a geosynchronous orbit directly over the Mads' castle]] and adjusted appropriately -- Brain Guy gently prodded Mike back up the ladder by pointed a cannon at him.[[/note]], or trying to invoke a Joel-style escape while sitting in a water heater after seeing ''Film/FinalJustice'' (starring Joe Don Baker, of course). He also has elements of GoingPostal, such as wearing a KubrickStare while quoting ''Film/FullMetalJacket'' or getting a ThousandYardStare thinking about an ex co-worker he thought had it out for him.
* ShirtlessScene: He's done this a few times.
--> '''Crow''': "Ladies and... [[TheSmurfettePrinciple Gypsy]]! Michael Nelson ''is''... Lord of the Dance!"
* TheStoner: During ''Film/LaserBlast'' the bots continuously compare him to the 70s stoner protagonist. He really doesn't deny the connection.
* StraightMan: To both the Mads and the Bots, in spite of his own oddness.
* StylisticSuck: Mike the character often sings off-key. Mike the actor sings quite well, however, as evidenced by the fact he sings the OpeningTheme in its post-KTMA iterations. He also harmonizes on such songs as "Tubular Boobular Joy" and "Merry Christmas - If That's OK".
* SuspiciouslySimilarSubstitute: Averted, Mike was ''very'' different from Joel. Unlike his predecessor he actively tried to escape from the SOL, gave up on the traditional invention exchanges early on, and was generally more biting and harsh in his riffing style.
* TapOnTheHead:
** ''"...so they conked him on the noggin and they shot him into space..."''
** He also gets one when he thinks he's James Lipton, thinking Crow is Ray Liotta.
* ThisLoserIsYou: "Just a regular joe they didn't like."
* UnfazedEveryman: He seems to be pretty cool with being stuck on a satellite forced to watch cheesy movies with robots that destroy his belongings all the time besides the occasional SanitySlippage and escape attempt.
* UnluckyEverydude: At the hands of Tom and Crow.
* WaitingForABreak: Apparently a very talented and prolific stage actor, still had to resort to temp work. It also applies to how he joined the show in RealLife. Originally hired away from TGI Friday's to do "some typing," everyone was very surprised at his joke writing and musical skills, resulting in him soon becoming head writer and getting numerous cameos, and then being the natural choice to replace Joel.
* WholesomeCrossdresser: Not so wholesome when he became Captain Janeway.

[[folder:Jonah Heston]]
->'''Played by''': Jonah Ray

The third "guy shot up in space" and the first one of the revival. A former pilot for Gizmonic Institute where he was regarded as a LivingLegend by the staff there. Initially seen by the bots as step-dad.
* TheAce: Treated as such by the Gizmonic Institute staff prior to his kidnapping.
* AcePilot: Apparently one of the best space pilots the Gizmonic Insitute had.
* {{Adorkable}}: Gets really excited about practical effects, loves making models and visual aids, loves tinkering, and doesn't shy away from silly costumes. Combine with his looks for one adorkable jumpsuit clad huaman.
* AllDrummersAreAnimals[=/=]DumbAndDrummer: Averted. Jonah plays a killer drum solo, but he's a friendly and polite guy who's also a genius inventor.
* {{Asteroid Miner|s}}: The prologue to the ''[[Recap/MysteryScienceTheater3000S11E01Reptilicus Reptilicus]]'' episode has him towing "the largest cache of precious meteors the world has ever known" back to Gizmonic Institute's Galactic Mining Strategies subsidiary before he's caught in Kinga's trap at Moon 13.
* TheBigGuy: At a staggering 6'5" he is the tallest host so far, towering over Tom, Crow, and even making Gypsy look dainty by comparison. Kinga calls him a "big stack of flapjacks". It even kind of breaks the illusion that he's sitting in a movie theater seat.
* BiggusDickus: [[GettingCrapPastTheRadar Subtly implied]] and PlayedForLaughs. During one of the host segments in the ''{{Film/Starcrash}}'' episode, he mentions that if he were to wear a spacesuit, it "would need a little extra room in the groin-al region." (Given the bots' [[TooMuchInformation reaction]], he probably wasn't referring to to his height...)
* BunnyEarsLawyer: The Gizmonic Institute staff also view him this way.
* ButtMonkey: Joel was the Bots' father, Mike was their big brother, Jonah is the kid next door. He also has to re-live and re-enact his kidnapping ''every single episode'' since Kinga's "Liquid Television" tech can only stream and not record.
* CatchPhrase: "We got Movie Sign!"
* DeadpanSnarker: Like most of the cast, especially when in the theater. On the scale of deadpan vs snark he falls somewhere between Joel and Mike (not nearly as deadpan as Joel, but a bit less biting with snark than Mike). He's willing to drop the snark to comment on when a film is genuinely doing something right.
* DitzyGenius: He's a GadgeteerGenius on par with Joel, but seems to be distracted easily. It was implied his MessageInABottle severely underplayed his need to be rescued before veering off script completely to talk about his childhood. He's also pretty gullible, believing the bots yarn about a ''Carnival Magic'' expanded universe, identifying himself as an easy mark despite his issues with the space circus scam, and getting fooled by Kinga's distress signal in the first place.
* GadgeteerGenius: He's a Joel-level tinkerer, making improvements to Gypsy and Tom, developing his "Percussion Drive" and frequently making models and visual aids.
* NoGoodDeedGoesUnpunished: He was tricked into landing at Kinga's base by a phony distress call, even unhesitatingly dumping his valuable cargo to answer it.
* NiceGuy: Jonah doesn't seem to have a mean bone in his body and was captured expressly because he was trying to help someone else. He also makes it a point to draw attention to legitimately impressive practical effects used in the movies
* OneOfUs: Unlike Joel and Mike, Jonah references a lot of more recent references, including ''Anime/SailorMoon'', ''Tabletop/DungeonsAndDragons'', ''WesternAnimation/TheTransformers'' and more.
** He also engages in some of the long RunningGag riffs, implying he's watched some of the original experiments and states in the re-pilot that he's heard the theme song somewhere before.
** He's a big fan of practical special effects, always pointing them out even while Crow and Tom don't quite get what the big deal is.
* PermaStubble: Crow demands to know why he doesn't shave.
* PetTheDog: He's quick to point out the rare occasions that a movie actually does something impressive, no joke involved.
* ThePollyanna: Of all the hosts, Jonah is the most upbeat and most inclined to look on the bright side. If he's ever dejected or down, it never lasts for very long.
* ShoutOut: Much like Joel Robinson above, Jonah's last name is a reference to actor [[Creator/CharltonHeston Charlton Heston]], who is famous for starring in [[PlanetOfTheApes1968 the original Planet of the Apes]].
* RageBreakingPoint: Don't do an OverlyLongGag and run it into the ground. Tom will attest to that when Jonah pulled off his dome and threw it away in ''Starcrash''.
* SmartPeopleWearGlasses: He wears glasses and is an inventor.
* SpaceTrucker: Jonah's Backjack cargo tug is based on a Freightliner cab-over cargo truck (think G1 [[WesternAnimation/{{Transformers}} Optimus Prime]]).
* SuperGullible: has shades of it. He fell for a phony distress call, believes a rather ludicrous claim from the bots that there's a ''Carnival Magic'' expanded Universe, identifies himself as an easy mark to PT Mindslap despite noticing how sketchy the whole deal is etc. Downplayed slightly if only because Max and the bots can sometimes be even more easily swayed.
* TeamDad: Seems to ''want'' to be this, trying to point out when someone is a bad role model or helping ease the bot's worries, but doesn't quite have enough respect from Crow and Tom to pull it off. Jonah Ray described his relationship to the bots as being more like the little brother of the kid next door who just really wants the other kids to like him. "You're not my real father, mister!"
* UnfazedEveryman: For the most part he's pretty cool with playing along with Kinga's experiment sans the ocassional escape attempt and if anything seems to embrace the general craziness around him.
* UnluckyEverydude: See butt monkey.
* YoureNotMyFather: Crow throws this at him verbatim. (In fairness to Jonah, [[RunningGag Crow used to tell Joel this as well]].)

!!The Bots

[[folder:In General]]
* CuteMachines: Relatively speaking.
* TheGenieKnowsJackNicholson: How they can make over hundreds of pop culture per episode despite being robots who have never been to Earth before, we'll never know.
** Joel sometimes implies that he programmed the references they didn't get from the T.V. into their memories.
** Justified in the revival, as they'd last been seen living on Earth even if they ended up back on the Satellite of Love by means [[MST3KMantra we really don't need to worry about]], and probably picked up any newer pop culture references while living down here.
* PingPongNaivete: How much they know and understand about human life changes depending on what's funniest. At the very least they have a working knowledge of pop culture.
* SecondLawMyAss: Applies to Crow and Tom Servo. Sometimes Gypsy as well. [[UpToEleven Even Cambot at one point]].
* RobotBuddy: A very loose definition of "buddy".
* RidiculouslyHumanRobot: They all have distinct personalities, in addition to being capable of dreaming and free will.
* StylisticSuck: They look like they were put together with whatever could be found lying around. This is justified by their in-universe origin (they were built by Joel out of... whatever he could find lying around), and out-of-universe because it's a lampshade of the MST3KMantra.
* {{Tsundere}}: Show mixed traits towards Mike in the Sci-Fi Channel episodes, with Crow showing elements of a classic Type A.
* WithFriendsLikeThese: Especially between Tom and Crow.

[[folder:Crow T. Robot]]
->'''Played by''': Josh Weinstein (''Invaders from the Deep'' only), Trace Beaulieu (KTMA through season 7, Great Gila Monster Sketch, Turkey Day 2014), Bill Corbett (seasons 8-10), Hampton Yount (season 11)

TV's wise-cracking Crow is a gold-colored hominid. His most obvious features are his pronounced beak made out of a bowling pin, and a hockey mask he wears as a head crest of sorts. He tends to be the most immature of the trio, generally acting out the most or getting into various types of trouble, referred to as "an unathletic nerd" by Mike and Servo. He also fancies himself a bit of an amateur screenwriter, and a RunningGag on the program is him routinely pitching new scripts at the other two. He sits to Joel/Mike/Jonah's right in the theater.
* BiTheWay: He wrote songs for his love of Kim Cattral and Estelle Winwood, but also has kinky dreams about Servo and fawns over Robert Redford.
* BrilliantButLazy: He's smarter than he appears, but gets bored easily and often doesn't bother to put in more than the minimum amount of effort on whatever he's doing. Says a lot that when taking an IQ test he failed to answer even one question because he fell asleep - and drooled on the test somehow.
* ButtMonkey: Particularly when Trace played him, he was the butt of quite a few jokes and suffered more than his share of AmusingInjuries.
* CatchPhrase: "You're not my real father!" was often hurled at Joel. He wanted to adopt "You know you want me, baby," as his personal catchphrase, mostly to justify a large order of T-shirts, but it didn't stick. Season 11 gave him [[HehHehYouSaidX "He/She/They said 'area!'"]]
* {{Cloudcuckoolander}}: His mind works in strange ways, even when ''not'' in the midst of a SanitySlippage. It's not always easy to tell when his more wacked-out ideas are just him joking around and when he's being serious.
* CriticalResearchFailure (InUniverse) / BlatantLies: Whenever Crow is called upon to do a research assignment on some historical figure, his results start out okay but soon go delightfully OffTheRails.
* DeadpanSnarker: Arguably the biggest one on the show.
--> '''Robot Roll Call''': What a wise-cracker!
* {{Determinator}}: How does Crow deal with being a ButtMonkey? According to him, "persevere".
* FatherIWantToMarryMyBrother: In "Racket Girls" he asks Mike for [[HoYay Tom Servo's hand in marriage]]. Yes, there is a wedding held. And yes, it is ''glorious.'' The wedding's never mentioned again after that episode, so it's probably safe to say that it held no legal standing and was just for shits and giggles.
** ChaoticNeutral: Pretty much everything they do is for shits and giggles.
* HeroicComedicSociopath
--> '''Joel''': And what do ''you'' want for Christmas, Crow?\\
'''Crow''': I wanna decide who lives and who dies!\\
'''Joel''': Oh I don't know...
* HilariouslyAbusiveChildhood: Joel had a... weird relationship with him.
-->'''Crow''': Did I ever tell you about the time Joel had me dressed as Judy Garland and had me sing show tunes to him all night? I have a lot of pain.
* KubrickStare: Can pull off a very good one, due to the way his head is shaped.
* TheLancer: Causes the most problems out of all the bots.
* LargeHam: Especially when voiced by Trace Beulieu.
* LikesOlderWomen: His two crushes, Kim Catrall and Estelle Winwood, were both beyond his age level, whatever that is.
* TheMcCoy
* MeaningfulName: Depending on when you ask him, Hodgson named Crow in honor of a Native American college friend with the same surname, or was inspired by the Jim Carroll Band song of the same name.
* MoralityPet: He's good friends with Pearl Forrester, of all people, and she treats him better than the rest of the cast.
* MysteriousPast: Crow spent almost all of the 500 years in the Satellite of Love (being pure energy was boring). Even he can't remember what he did, but apparently a large chunk of it was spent eating Nut Goodies and at one point, he tried to conceive (and made a fertility idol of himself to try to help out.)
* TheNthDoctor: Bill Corbett was TheOtherDarrin until a joke that his voice changes "every seven years or so" and a throwaway line by [[TheBusCameBack Joel]] saying that he'd changed his "bowling pin" part, making him TheNthDoctor.
* SanitySlippage: He's more likely than Servo to descend into madness - and just as easily to MoodWhiplash himself into normalcy. For example, when Crow suckles at his "Mother's" nipple, he shrieks a primal scream when Mike tries to pull him off her - but a few moments later, when Mike gently tells him "That's not your mother", he pauses, and says, "Oh!"... then quickly asks him, "Are ''you'' my mother?"
* SpellMyNameWithAThe: His middle name.
* SphereEyes
* SplitPersonality: In the Sci-Fi Channel episodes, Crow has an occasional tendency to think he's something or someone he's not. Examples include [[http://www.youtube.com/watch?v=OnwCv1E43oU a bear]] (''[[Film/{{Morozko}} Jack Frost]]''), [[http://www.youtube.com/watch?v=7pBDZz9kzFM Mary Tyler Moore]] (''Film/ItLivesByNight''), and [[http://www.youtube.com/watch?v=Bcqg-d52ZvM a Bellerian]] (''Film/SpaceMutiny''). Very likely a result of SanitySlippage after he'd been on the Satellite for 500 years.
* TheStarscream: MirrorUniverse Crow.
* StylisticSuck: His forays into screenwriting, especially the infamous ''[[RunningGag Earth Vs. Soup]]''.
* TelescopingRobot: Crow's arms look disproportionately small when he's behind a counter. A full body shot reveals he's really just folded his arms up to fit on the counter. This effect is much less prominent in the 2017 revival, where his arms are not only noticeably thicker, but much more animated.
* TransparentCloset: Has had at least one kinky dream about Tom Servo, and gotten giggly over the thought of touching Robert Redford.
* UsefulNotes/{{UNIX}}: Crow runs mainly on Unix, according to ''[[Recap/MysteryScienceTheater3000S04E21MonsterAGoGo Monster a Go-Go]]''.
* VitriolicBestBuds: With Tom Servo, Type 2.

[[folder:Tom Servo]]
->'''Played by''': Josh Weinstein (KTMA - season 1, Turkey Day 2014), Kevin Murphy (seasons 2-10), Frank Coniff (Great Gila Monster Sketch), Baron Vaughn (season 11)

Tom Servo is a red robot. His most obvious feature is the fact that his head is a gumball machine. He also has inoperable arms on springs, and travels by floating on his hover-skirt. Despite these shortcomings, he's the most cultured of the crew and has a lovely singing voice. His jokes tend to be of the more intellectual type. He sits to Joel/Mike/Jonah's left in the theater.

* AbnormalLimbRotationRange: He can rotate his body while his head stays in the same place.
* BerserkButton: '''[[Film/TheRebelSet HE'S NOT MERRITT STONE!]]'''
* BiTheWay: Usually a CasanovaWannabe, but he also [[FatherIWantToMarryMyBrother married Crow]] in "Racket Girls" and fawned over Robert Redford.
* CasanovaWannabe: Mainly his KTMA-Season 1 persona.
* ConditionedToAcceptHorror: "Future War" reveals he sees everything as a DisneyAcidSequence. He doesn't seem troubled by it at all.
* DeadpanSnarker: As with the difference between Joel and Mike, Weinstein's Servo is more Deadpan, and Murphy's Servo is more Snarker. Coniff and Vaughn also play him very deadpan.
* DistressedDude: Has gotten into this role a couple of times.
* EyelessFace: It's implied either the gumball dome or the red rim under it is his eyes.
* FatBestFriend: Kevin Murphy has affectionately commented on Tom being "portly", and his entire design is a little rounded and squat to convey stoutness. It's even present when he dons clothing -- his jutting keypad tends to accidentally give him a prominent middle.
* FatherIWantToMarryMyBrother: With Crow in "Racket Girls". Tries to go on a date with Gypsy in "Swamp Diamonds."
* FullNameBasis: He was usually referred to as "Tom Servo" or "Servo". Only Joel and Jonah regularly called him just "Tom".
* GeniusDitz: Not exactly the most lucid robot, but he managed to outscore the Observers in an intelligence test and casually bends reality to mess with Crow. His explanation for the test score was that he [[CrowningMomentofFunny just tests well.]]
* HeroicBSOD: He has had ''a lot'' of nervous breakdowns throughout the series.
* InTouchWithHisFeminineSide: Constantly wearing dresses and wigs.
* LargeHam: Gets into this on occasions. Especially during his "MIGHTY VOICE!" days.
* MesACrowd: After he was cloned in ''Film/TheHumanDuplicators'', it became an occasional RunningGag for the rest of the show's run that there are a bunch of other Servos hanging around somewhere on the satellite. In the final episode [[spoiler:he blows them all up]].
** The gag gets revisited in Season 11's ''Reptilicus'' when Crow takes Tom's arm and regenerates a whole crowd of Servos out of it. FridgeHorror comes in as a close look at the scene reveals the Servo they end up with is ''not'' the one they started with.
* MotorMouth: Made the longest riff on the show; an entire minute and a half during ''[[Recap/MysteryScienceTheater3000S04E24ManosTheHandsOfFate Manos]]''. He also talked nonstop through an entire segment (and then some) during the "Moment of Silence" from ''[[Recap/MysteryScienceTheater3000S06E24SamsonVsTheVampireWomen Samson Vs. the Vampire Women]]''.
* MysteriousPast: Tom apparently had a wild life of adventure during his time an energy being on the edge of the universe, which he refuses to talk about.
* TheNapoleon: MirrorUniverse Servo, but also Tom himself on occasion.
* RaceLift: A vocal example in the revival: his new voice is a black guy. Apparently that's what he'd secretly wanted.
* RealityWarper: During ''The Gunslinger'', Tom Servo shows that he has such a complex understanding of reality that he's able to perform OffscreenTeleportation and warp time. He apparently uses it to [[MundaneUtility scare Crow at night]].
* RenamedTheSame: When he changes his last name to Sirveaux, in the ''Hamlet'' episode. It's pronounced exactly the same, but he thinks he can tell when people aren't pronouncing it right.
* RuleOfFunny: Though it's frequently stated that his arms are nonfunctional, he nonetheless will be able to grab objects if it leads to a punchline.
* SendInTheClones: There's about 517 of him running around the ship by the end. [[Recap/MysteryScienceTheater3000S10E13Diabolik Diabolik]] has him activating the self-destruct in them, despite not knowing if he's a clone or original.
* SmallNameBigEgo: In spades, and usually BreakTheHaughty follows in quick order.
* TheSmartGuy: So much so that when the Observers gave the satellite crew IQ tests, he scored ''higher than Bill!Observer (aka Brain Guy),'' though he admits he isn't that smart - he just tests well.
* SpellMyNameWithAnS: At one point he changes his name to Htom Sirveaux, and corrects Mike when he doesn't pronounce it correctly (even though it's pronounced exactly the same.)
-->'''Crow''': Well, Htom, why don't you hlick me!
* TheSpock: If, as Murphy puts it, "kind of weepy".
* TheyKilledKennyAgain: [[JustifiedTrope Justified]] since he has thousands of replacements for himself. In ''Reptilicus'' he's melted down and replaced by a clone, who comes clean that he's not the original, but the others don't care.
* ThroughTheEyesOfMadness: At one point Pearl gives LSD to the robots and has Mike hook them up to a monitor to see what they're seeing. From Servo's point of view, Crow and Mike are gibbering monsters while his vision kaleidoscopes into a mad swirl of horrible colors and shapes. But he laughs it off and says that that's what he ''always'' sees.
* TransparentCloset: Not quite as flagrant as Crow, but he ''is'' curvy, gifted with better fashion sense, and the best singer on the ship.
* VitriolicBestBuds: With Crow.
* WholesomeCrossdresser: If someone's going to get in a skirt as part of a skit, it'll probably be Servo. {{Lampshaded}} when Servo dresses as a Brownie. He angrily tells them that his hoverskirt doesn't give him many options when wearing costumes - or would you rather he wear his Flemish glass blower outfit? WordOfGod is that the puppet's shape just happened to fit female costumes the best.
* YesMan: Becomes a rather meek one to [[{{Jerkass}} Eddie]] in the AlternateTimeline during ''Time Chasers''. Thankfully it's only temporary.
* YourHeadASplode: Even more than the other Bots.

->'''Played by''': Josh Weinstein (KTMA), Jim Mallon (seasons 1-8), Patrick Brantseg (seasons 8-10), Rebecca Hanson (season 11)

Gypsy was a robot built by Joel to service the higher functions of the ship. As such, she doesn't (typically) go into the theater with everyone else. She's basically a snake form, with a long black tube as a body, and her head is a baby's car seat attached so she kinda looks like a vacuum cleaner with a flashlight that serves as her eye. She has a ''huge'' crush on Richard Basehart.
* AscendedExtra: She gets a much expanded role in the 2017 revival, regularly showing up in the theater to deliver her own riffs. This is aided by a new puppet setup that descends from the ceiling, eliminating the weight problem that limited her use in the original show.
* CharacterizationMarchesOn: She was ''incredibly'' dim-witted - her personality was, after all, based on that of a ''turtle'' Joel Hodgson knew - until about midway through Season 2, when the crew realized [[UnfortunateImplications that wasn't the best trait for the show's only female character to have]]. From there she developed her WomenAreWiser characterization.
* CloudCuckoolander: A running gag is that she is the smartest character by a wide margin, but most of her mind is taken up by actually running all the systems on the ship.
* CrouchingMoronHiddenBadass: See SmarterThanYouLook.
* TheDitz: While she was almost [[YouNoTakeCandle completely]] [[TheUnintelligible unintelligible]] in the KTMA episodes, this became gradually [[DownplayedTrope downplayed]] as the series went on, until she was more or less the [[CloudCuckoolander (admittedly not completely lucid)]] OnlySaneWoman during the Sci-Fi seasons.
* DumbassNoMore: As mentioned before, she was always intelligent (if somewhat overtaxed), but beginning in the revival, the SOL became tethered to the Moon, eliminating her need to monitor the life support and giving her enough processing power to make her the smartest of them all. She even chimes in with one joke per movie, something the old Gypsy failed terribly at.
* ImYourBiggestFan: Toward ''Series/VoyageToTheBottomOfTheSea'' star Richard Basehart.
* LarynxDissonance: Was voiced by male actors during the show's original run. This ironically makes it sound quite weird in its own right to hear her with a real woman's voice in the 2017 revival.
* MamaBear: Towards Crow and Tom Servo, most notably in "The Beatniks."
* MeaningfulName: Joel Hodgson named and designed her after his brother's pet turtle. [[NotMakingThisUpDisclaimer Really]].
* OnlySaneWoman: Believe it or not, she's been this at times.
* SmarterThanYouLook: Discussed; the reason for this is Gypsy has a hard time controlling the SOL and being able to interact with the others at the same time, but she eventually gets the hang of it.
* TeamMom: Especially to Tom and Crow.
* SassyBlackWoman: Parodied; during an experiment in season 6 that made the Bots more pretentious, Gypsy called Mike her "white male opresser." But it didn't stop there. In Season 10, Gypsy ([[ItMakesSenseInContext who had]] TookALevelInJerkass [[ItMakesSenseInContext thanks to the ship going haywire]]) told Mike [[CrossesTheLineTwice to "jump up my tube, white boy!"]]
* SelfMadeMan: [[spoiler:After the SOL's crash (at the end of the series) she ditched Mike and the other Bots and founded a multi-billion dollar company. Though since this was 1999 and near the peak of the dot-com bubble, when even Wiki/TVTropes might have been valued in the billions, it's sort of an open question whether her fortune lasted.]]
* SmurfettePrinciple: She's the only female robot on the Satellite Of Love.
-->'''Gypsy''': Well, I'm ''pretty sure'' I'm a woman.
* YouNoTakeCandle: Only at first. She got over it after a few seasons.

->'''Played by''': Kevin Murphy (KTMA), Joel Hodgson (season 1-5) and Michael J. Nelson (season 5-10), although he is only heard during RobotRollCall in the official seasons.

Cambot serves as the camera on the Satellite of Love, projecting to the Mads in Deep 13. As such, he's never seen, never heard, and it's easy to forget he's even there, but he's obviously an essential member of the crew, without whom we wouldn't see all the wacky hijinx on the Satellite.
* CameraAbuse: Got attacked by [[EvilTwin Timmy]], unplugged once by Joel, and had champagne spilled onto his sequencer in the middle of a music number.
* EarlyInstallmentWeirdness: The KTMA episodes had Cambot actually be a more humanoid robot with bug-eyes who filmed with a separate camera[[note]]his name was not mirrored, to boot[[/note]]. Season 1 introduced his more familiar "autonomous camera" design.
* EvilAllAlong: In a Kickstarter update, Joel considered that, despite being featured in the Robot Rollcall, Cambot was probably aligned with the Mads, since it was integral to their experiment. The new design will be taking this into account.
** When looking at a fan's drawing of the old show, Jonah refers to the "floating orb" Cambot as "Old Cambot", suggesting that the one in the revival is not the same character.
* HeWhoMustNotBeSeen: Kind of a given, since he's the one who has to film everything.
* InUniverseCamera: Invoked, as Joel built him specifically to be this.
* LastNameBasis: If "Bride of the Monster" is to be believed, his first name is Mort.
* NotSoStoic: See TenderTears below.
* TheNthDoctor: Cambot went through four different bodies over the course of the show (five, if you count changing paint jobs).
* PhraseCatcher: "Cambot, give me Rocket Number Nine!" Except for one time when it was "Cambot, give me Rocket Number [[ExpospeakGag Eleven Minus Two!"]]
* RunningGag: Mike, Joel or Jonah calling "Cambot, give me Rocket #9!" any time something is happening outside the ship. No matter ''what'' is being looked at, external visual is ''always'' from Rocket #9.
* SdrawkcabName: During RobotRollCall his name is backwards because he's taping himself in a mirror.
* SilentSnarker: Made his only riff in 'Sidehackers', though makes a few jokes in the host segments here and there.
* TenderTears: In the ''Film/DangerDeathRay'' review the deaths of so many innocent cameras leaves him crying through the last host segment, blurring out the scene.
* TheVoiceless: Except during the Robot Roll Calls.

[[folder:Magic Voice]]
[[caption-width-right:313:Fan art by Andrew Dickman]]
->'''Played by''': Jahn Johnson/Alexandra Carr (seasons 1-5), Mary Jo Pehl (seasons 5-7) and Beth "Beez" [=McKeever=] (Seasons 8-10)

Magic Voice is a female, disembodied voice who resides in the Satellite of Love, and whose main task is to announce when commercial sign is coming up and otherwise make the occasional comment on the action. It's never revealed exactly what she is, but seems to be robotic in nature, given how Joel was able to reprogram her along with the other 'Bots. The most common fan theory is that she's the ship's computer.
* ADayInTheLimelight: A minor presence in the show who usually just chimed in with short comments and announced upcoming commercial sign, she did get a few skits and segments where she received more attention, most notably in the fifth-season episode ''"The Atomic Brain'', where she feels lonely and wishes she could meet someone else like her but changes her mind after an encounter with the creepy voice-over guy from the episode's movie.
** She also counsels Tom Servo about making out in ''Attack of the the Eye Creatures''.
* ChuckCunninghamSyndrome: She's one of the few characters to vanish from the show with no real explanation.
* DeadpanSnarker: Not to the extent of Joel/Mike and the Bots, but she gets a few good lines in from time to time.
* OutOfFocus: While never a major presence in the show, she appeared less and less in later seasons, and in the Sci-Fi years only made the odd cameo before vanishing completely in season 10.
* TheVoice: Literally; she is only a voice and lacks any sort of corporeal form.

[[folder: The Nanites]]
Something Crow picked up in the 500 year time gap between season 7 and 8 at a space carnival, he only got two of them, but they reproduced like sea monkeys do, and there are now billions of them on the Satellite of Love. They're capable of almost anything, but are rather unwilling to do anything without a work order.
* TheBully: Mooki the Nanite is from the bad side of the Satellite, and Servo makes the misfortune of stepping on his turf when he tries to join the Nanites.
* ComplexityAddiction: Their ideas for distractions include constructing micro-size battle fleets that pull people's pants down and synthesizing an android programmed to say: "Hey, look over there!"
-->'''Mike''': Can't you just cut the tractor beam holding us here?\\
'''Nanite #1''': ''(disappointed)'' Eh, a Number 5, sure.\\
'''Nanite #2''': We never get to have any fun!
* ExplosiveBreeder: Crow won two of them at a space carnival. 500 years later and they cover every surface of the ship.
* MurderIsTheBestSolution: When the Observers cut off the [=SoL=]'s navigation systems, Mike asked them to take care of it. Cue EarthShatteringKaboom.
* ObstructiveBureaucrat: The nanites won't do anything unless they have the paperwork in writing, even if the ship is seconds away from being destroyed.
-->'''Nanite''': Hey, man, I don't go to the ''john'' without a work order!
* LiteralGenie: When asked for tall hair or the dry look, Mike was given mile high hair and a literal desert on his head.
* WeirdTradeUnion: Actually had a strike, which delayed the Satellite's repairs for a week, until nanite strike breakers came in and busted the strike. It's not entirely clear who ultimately won; in their next appearance they were back on the job and had picked up a NotInMyContract attitude.

!!The Mads
[[folder:In General]]
* AffablyEvil[=/=]FriendlyEnemy: They've all had their fair share of chummy moments with their captives.
* CoolAndUnusualPunishment: Refusal to go into the theater is met with either electrocution or the removal of the ship's oxygen.
* FailureIsTheOnlyOption: None of the movies will ever [[GoMadFromTheRevelation break the SOLites' will]]. Although they have gotten close on a number of occasions.
* IneffectualSympatheticVillain: The Satellite Of Love crashing bringing an end to the experiments (and therefore the show) in Diabolik reduced Pearl to tears, with her makeup running and her hair in a mess.
** Dr. Forrester when Frank died, especially displayed in his song "Who Will I Kill?"
* LargeHam: Dr. Forrester and Pearl.
* SuspiciouslySimilarSubstitute: TV's Frank to Dr. Erhardt; Pearl to Frank, and later Dr. Forrester; though to be fair while they filled similar roles their characters were all quite different.

[[folder:Dr. Clayton Forrester]]
->'''Played by''': Trace Beaulieu

Dr. Forrester is the green-coated head scientist down in Deep 13 who oversees the experiment on the Satellite of Love. While he's evil with a capital E, he's also not particularly effective, given how after several years, he still has yet to find that perfect movie that will drive people insane. Oftentimes, the relationship between Dr. F and the folks on the Satellite tends to be strangely amicable.
* AdaptationalVillainy: He's noticeably more sadistic in TheMovie than he is in the series proper, going so far as actually cutting off Mike's air supply when he gives him lip. He lampshades this when he first appears, saying that he's "feeling particularly evil today". It also may have something to do with the movie being right after [[HeterosexualLifePartners Frank]] left.
* AffablyEvil: Though a megalomaniacal MadScientist who tortures his captives with bad movies, abuses his assistant and takes pride in being Evil, he's got surprisingly many friendly moments.
* BadBoss: Especially to Larry.
* BerserkButton: As Mike found out in his first experiment, Dr. Forrester does not like being kept waiting.
-->'''Dr. Forrester''': Oh, Mr. Nelson. Mr. El Relaxo. That's nice. Maybe I'll...just...have...you...do your ''invention exchange first! First! DO YOU HEAR ME? FIRST!!''
* CardCarryingVillain: "Supervillain" is his actual job title.
-->'''Dr. Forrester and Dr. Erhardt''': What do you want from us? WE'RE EVIL!
* CharacterizationMarchesOn: Started out as a smug, stern, pompous, deeper-voiced jerk but eventually became a manic, mincing, [[Series/MatchGame Charles Nelson Reilly]]-ish maniac.
* ClarkKentOutfit: As can be seen in the ''San Francisco International'' episode, underneath the scrubs, Doctor Forrester is ''cut''!
* EinsteinHair: From Season 1 onwards.
* EmbarrassingMiddleName: Deborah Susan
* EvenEvilHasStandards: He actually ''apologizes'' to Joel for showing him ''[[Recap/MysteryScienceTheater3000S04E24ManosTheHandsOfFate Manos: The Hands of Fate]]'', which is odd given the show's premise, but once you see the movie you'll understand.
* EvilSoundsDeep: In KTMA, almost to the point of NightmareFuel.
* HilariouslyAbusiveChildhood: His FreudianExcuse includes a mother who doesn't seem to care about his existence, rejection from every girl in high school, several [[NoodleIncident Noodle Incidents]] involving ice rinks, the shower incident, and a humiliating expulsion from the chess club.
* InsultBackfire: He gets all warm and fuzzy when he's accused of crimes against humanity (or robotity).
-->'''Joel''': That may be the most despicable thing I've ever heard of.\\
'''Dr. Forrester''': ''[smugly]'' Thank you!
* LockedIntoStrangeness: According to his BackStory, he was struck by lightning, which gave him his SkunkStripe.
* MadScientist: A textbook example.
* NerdGlasses: The ''[[Recap/MysteryScienceTheater3000S03E01CaveDwellers Cave Dwellers]]'' [[Recap/MysteryScienceTheater3000S03E01CaveDwellers episode]] had them change from green to black [[BigLippedAlligatorMoment with no explanation, and was never mentioned again]].
** Beaulieu himself during a Q&A explained that he had accidentally left his only pair of green glasses in the pocket of his lab coat (they had 2 lab coats that they switched out each episode), and that coat was sent to the dry cleaners. By the time he realized his mistake, it was too late to get them back before filming of the episode was to commence, so he slapped on an old pair of Dr. Erhardt glasses so they wouldn't have to delay filming.
* ShoutOut: He's named after the hero of the 1953 film adaptation of ''Film/TheWarOfTheWorlds'', and Joel has commented that much of his later petty, fussy characterization was inspired by Dr. Fate from ''Film/TheGreatRace'' (including his catch phrase of "push the button").
* SkunkStripe: In his hair ''and'' mustache. Trace has hinted during a convention panel that it also appears in a third place [[{{Squick}} (the location of which is for the reader to decide)]]. Apparently got it after getting struck by lightning.
* StopHavingFunGuys: [[invoked]] During "Turkey Day '91", he's more concerned with world domination than Thanksgiving.

[[folder:Dr. Laurence "Larry" Erhardt]]
->'''Played by''': Josh Weinstein

Dr. F's first assistant, who didn't get much characterization at all, since he was only around for one season. He pretty much aped Dr. F's tendencies towards loving evil and played the part of the sniveling aide.
* FaceOnAMilkCarton: The last we see of him in ''Recap/MysteryScienceTheater3000S02E01RocketshipXM''.
* FreudianExcuse: Apparently used to work at a zoo before they gave him monkeys instead of students.
* GeekPhysiques: Of the fat variety.
* TheIgor: Turned into one over the course of the KTMA season; at first he was more clearly Dr. Forrester's partner and equal, but became more of a subservient toady over time.
* LaughingMad: In the KTMA shows, not so much in the Comedy Channel shows, where he became more of a bungling assistant to Dr Forrester.
* NerdGlasses: Just like Dr. Forrester, he sports an impressive pair.
* MadScientist: The main difference between TV's Frank and Dr. Erhardt is that Dr. Erhardt is a MadScientist in his own right.
* PhraseCatcher: "File this, Larry."
* ProfessionalButtKisser: Larry constantly sucks up to Dr. Forrester.
* PutOnABus: And later implied to have been [[BusCrash eaten by a giant spider]].
* TookALevelInKindness: In the KTMA episodes, especially his earlier appearances, he was a lot more unhinged and showed some sadistic tendencies. By the time the show moved to Comedy Central, he'd mellowed out a lot and was downright jovial and friendly -- though never ''quite'' a MinionWithAnFInEvil.

[[folder:TV's Frank]]
->'''Played by''': Frank Conniff

Dr. Erhardt's replacement after Season 1, TV's Frank was, in the end, far more fleshed out than his predecessor. More laid back, goofy, and ineffectual than even Dr. F himself, Frank often found himself the butt of jokes, or just plain dead. He departed the show at the end of Season 6, where he was assumed into Second Banana Heaven.
* AffablyEvil: Every once and while Frank will show that he's as evil as Clayton.
-->'''TV's Frank''': [[PunctuatedForEmphasis You. Are all. Going]]. ''[[PunctuatedForEmphasis To DIE!]]''
* AscendedToAHigherPlaneOfExistence: When [[Film/ManosTheHandsOfFate Torgo the White]] brings him to Second Banana Heaven. His season ten cameo reveals he got kicked out later.
* AttentionDeficitDisciple: "Hike Your Pants Up" and "Mike Ma-ma-Mike" are good examples.
* AttentionDeficitOohShiny:
-->'''TV's Frank''': '''''WHY?! WHY?! WHY?!?!?!''''' Oooh, ''[=McKenna=]'s Gold'' is on!
* BigEater: Reached his limit in the second Turkey Day marathon, when Dr. F forces him to eat fifteen entire turkeys.
* BizarreHumanBiology: He's survived multiple kinds of dismemberment (has replacement organs!), having his blood replaced with antifreeze (blood which is of a previously-unknown type, by the way), and apparently exists in a state of perpetual cardiac problems (his heart works so hard it can power an engine).
* BurgerFool: Dr. Forrester found him working at an Arby's. His first episode had him try and take Joel and the Bots' orders.
* ButtMonkey: At the hands of Dr. F.
* CatchPhrase: Had one for his first season, a weird mouth sound that kind of came out as "Eeeukk-ghueeee!" Didn't last into Frank's second season.
* DeathIsCheap: Frank gets killed a lot.
-->'''TV's Frank''': Ooh, that's my old head! Just file that under "Frank's Old Head".
* TheDitz: Not as much as Bobo, but still.
* TheDogBitesBack: As badly as Dr. Forrester usually treats him, Frank turns the tables in ''Red Zone Cuba''. After borrowing fifty thousand dollars from the mob, Frank sends Dr. F out to speak to the mob enforcer at his doorstep. Dr. F gets pummeled so badly, he spends the rest of the episode in a full-body cast.
* FriendlyEnemy: With Joel, Mike and the Bots.
* MadBomber: After watching [[{{Film/Speed}} several]] [[Film/BlownAway action]] [[Film/InTheLineOfFire movies]] featuring assassins, bomb plots, and explosions, the easily suggestible Frank becomes a cackling, scheming lunatic who plots to blow up Deep 13. (Of course, he's still Frank, so he doesn't bother tying Dr. F's ropes very tightly, or even keeping track of his hostages.)
* MinionWithAnFInEvil: The reason why so many escape attempts hinged on trying to convince Frank to hit the button that would return the satellite to earth. It almost worked on multiple occasions, Forrester stopping him each time.
* PhraseCatcher: "Push the button, Frank!"
* ThePigpen: Implied, as one short about hygiene was picked out by Doctor Forrester specifically so Frank could watch it.
* PsychopathicManchild: The man-childishness was pretty consistent; the psychopathy waxed and waned, and its targeting was erratic- Frank could just as often be plotting Dr. Forrester's grisly demise during a friendly chat with Joel/Mike and the 'bots as the other way 'round.
* PutOnABus: To Second Banana Heaven.
* TheyKilledKennyAgain: He dies ''a lot.''
* TooDumbToLive: Literally, as he was killed multiple times.
* TransparentCloset: With Dr. Forrester. One sketch revolved entirely around them acting like a fussy old married couple when nobody's watching, and the guests at "Auntie [=McFrank's=] Tangleberry Inn" sheepishly ask just what he and Clay's relationship is after seeing Frank in a housedress and bonnet.

[[folder:Pearl Forrester]]
[[caption-width-right:336:Left, Deep 13. Right, Castle Forrester]]
->'''Played by''': Mary Jo Pehl

Dr. F's [[MyBelovedSmother beloved mother]], who showed up a few times in Season 6, but became Dr. F's foil in Season 7 when she moves back in. Starting Season 8, after Trace Beaulieu leaves the show, she becomes the head scientist showing the movies. The story is that after Clayton died (again, it's a bit complicated), she was put in cryogenic freezing, thawed by the future apes, and became the Lawgiver. Doesn't make much sense, but [[MST3KMantra you know how it is]].
* AbsurdlyYouthfulMother: Her actress is two years ''younger'' than the actor who played her adult son, and despite raising him In-Universe ''[[TimeyWimeyBall twice]]'' she still looks no more than middle aged. As usual, [[MST3KMantra the mantra applies]].
* AbusiveParents: She was never the best mother to Dr. Forrester -- and as the 2017 revival reveals, she's a pretty bad grandmother to Kinga as well. Stuck with raising her granddaughter, she apparently tried abandoning Kinga several times, but Kinga "always came back."
* AffablyEvil: In some situations, usually as a riff on the [[MinnesotaNice stereotypical good-naturedness of Midwesterners]].
* BlackWidow: She actually ''threatens'' Bobo and Observer, "Sit down, or I'll ''marry'' you!"
* BullyingADragon: She's able to control nigh-omnipotent Observer through sheer force of will (and threat of violence.)
* CardCarryingVillain: At least, her goal, as she desperately wants to join the Fraternal Order of Mad Scientists.
* CharacterizationMarchesOn: She appeared as an annoying, naggy, overbearing mother stereotype in the Deep 13 episodes, but morphed into a more bullying version of Dr. F when she took over as the main villain. Her first appearance also had [[GenerationXerox her looking uncannily like her son (right down to a small, fuzzy mustache on her upper lip)]], something that was toned down in subsequent episodes.
* CatchPhrase: "It's called (title of movie) and it sucks on toast."
* EvilHasABadSenseOfHumor: Both the "sadistic mad scientist" and "[[PointyHairedBoss clueless middle-manager]]" kind -- Pearl's personal idea of fun is inflicting cruelty on her subordinates, but in ''[[Recap/MysteryScienceTheater3000S10E08FinalJustice Final Justice]]'', she also forces Mike and the 'bots to endure [[IncrediblyLameFun the dull, forced levity of novelty glasses and "Wacky-Dress-Up Day"]], in the hopes that it'll liven up the workplace.[[note]]The one time she actually does manage to be funny on her own is when she enters the theater in ''Quest of the Delta Knights'', and that's because Mary Jo almost entirely breaks character for the segment.[[/note]]
-->'''Pearl''': ''(Completely flat monotone)'' Do-you-begin-to-see-how-creativity-can-lead-to-productivity?\\
'''Tom''': Well... no, I'm just kinda depressed.\\
'''Crow''': Yeah, mostly I feel sad, and... ache-y?
* TheGamblingAddict: In ''[[Recap/MysteryScienceTheater3000S08E16PrinceOfSpace Prince of Space]]'', she states that her favorite hobby is playing slot machines. And in ''[[Recap/MysteryScienceTheater3000S10E09Hamlet Hamlet]]'', Mike ropes her into playing a ShellGame and ends up winning his choice of a movie. Of course, Pearl turns the situation back in her favor by sending him a crappy, black-and-white, dubbed version of ''Theatre/{{Hamlet}}''. This continues into season 11: she makes a cameo in ''[[Recap/MysteryScienceTheater3000S11E02CryWilderness Cry Wilderness]]'' and blows off visiting Kinga to save her spot at her favorite slot machine instead.
* GladIThoughtOfIt: Pearl's usual reaction to good advice by Observer and Bobo. Neither of them bother to correct her, probably because she'll probably hurt them.
* HoistByHisOwnPetard: It's actually her fault the Satellite of Love finally went back to Earth in "Diabolik", since she both broke the joystick she was controlling it with, and messed with Brain Guy's powers so he couldn't intervene.
* LegacyCharacter: Especially once she moves into Castle Forrester in season 9.
* MadScientist: Spends most of Season 10 trying to get her license.
* MyBelovedSmother: Her original characterization with regards to Clayton. She also ''literally'' smothered him to death off-screen between seasons 7 and 8, when she didn't get around to raising the reborn Dr. Forrester and he grew up to be the same maniac he was before.
* NeverMyFault: The whole reason she took over as head Mad was because she blamed Mike and the Bots for Clayton's death after she smothered him to death with a pillow.
* PsychopathicWomanChild: She has ''many'' temper tantrums.
* "ReportsOfMyDeathWereGreatlyExaggerated, crapheads!"
* SkunkStripe: Apparently she was also struck by lightning.
* TenderTears: In "Diabolik" when the Satellite of Love crew finally escaped her clutches.
* TrademarkFavoriteFood: Noted to have a fondness for chicken-in-a-biskit snack crackers several times, to the point that Brain Guy uses it as motivation to prevent the destruction of the universe. No more universe, no more chicken-in-a-biskit.
* TwitchyEye: Has one driving her VW camper in the title sequence.
* WeirdnessMagnet: Invoked directly by her in ''[[Recap/MysteryScienceTheater3000S10E09Hamlet Hamlet]]'', when she asks the viewer, "Is it ''me''? Am I a magnet for these idiots?"

[[folder:Professor Bobo]]
->'''Played by''': Kevin Murphy

An evolved gorilla from the year 2525, from a ''[[Franchise/PlanetOfTheApes future where apes evolved from men?]]''. Yes, it's a madhouse. He's heard it all. First appearing in the beginning of Season 8, he's a professor of anthropology, but soon becomes little more than TheDitz often foiling Pearl's machinations.
* BatmanCanBreatheInSpace: Twice; first when falling off the Widowmaker and onto a nearby planet, and again when he had to... [[InsistentTerminology "go."]]
* ButtMonkey: Pun not intended. While Observer gets most of Pearl's verbal abuse, Bobo takes the lion's share of ''physical'' abuse, often being slapped, beaten, or knocked around.
* CharacterizationMarchesOn: While a bit dumb to begin with, Bobo started off as a more serious, OnlySaneMan head scientist in Deep Ape, often scolding his subordinates for being silly & exasperated at the stuff going on around him. Upon leaving Deep Ape he immediately became a doofus... eventually becoming not much more that a talking family pet. See OnlySaneMan & TookALevelInDumbass. His introduction in Season 8 can be a bit jarring to those used to "Bobo The Big Idiot Sidekick".
** NotSoAboveItAll: Though it's hinted he's a doofus in that while he insists he's intelligent, it doesn't take much prodding for him to wear a diaper like a domesticated chimp. Also, his idea of "research" is telling Peanut to play in a tire swing.
* TheDitz: Even moreso than Frank.
* DungFu: Bobo isn't above this, as Observer finds out to his horror.
* ExtremeOmnivore: He is constantly either eating or looking for food, and on top of that, is occasionally shown to eat things that aren't food.
--> '''Bobo''': Well, you see, the fact of the matter is I've swallowed so darned many things over the years that there must be a key in there ''somewhere'' that'll work.
** Which leads to this...
--->'''Bobo''': ''[regurgitates a hairpin]'' Ah, a hairpin!\\
'''Bobo''': ''[indignant]'' I did ''not'', Brain Guy! I swallowed a ''wig''.
* InsistentTerminology:
-->'''Peanut''': I'm Peanut!\\
'''Bobo''': That's ''Doctor'' Peanut! ''[{{dope slap}}]''
* MeaningfulName\BilingualBonus: Bobo is Spanish for "fool".
* MikeNelsonDestroyerOfWorlds: He may not be the TropeNamer, but Bobo shares just as much responsibility as Mike does in blowing up Earth. He did help repair the bomb that did it after all.
** He also [[BeenThereShapedHistory burned down Ancient Rome]] [[ItMakesJustAsMuchSenseInContext when he knocked over a candle trying to steal a cheese wheel]].
* OnlySaneMan: Was this back in Deep Ape. The very second they left, Bobo [[TookALevelInDumbass shoots himself in the foot]]. ''[[UpToEleven Twice]]''.
* SesquipedalianLoquaciousness: Has infrequent moments when he'll talk like this; even after he TookALevelInDumbass he kept a very advanced vocabulary and often spoke in a "cultured" tone.
* TookALevelInBadass: When he remembers he's descended from the line of "Godo, Gobo, and Chim-chim!"
* TookALevelInDumbass: Bobo wasn't exactly the brightest knife in the full deck before Earth blew up, but afterward he became a complete idiot.

[[folder:Observer ("Brain Guy")]]
->'''Played by''': Bill Corbett

A member of an allegedly advanced species, the Observers. He and his kind first appear in Season 8 to observe the experiment, but [[MikeNelsonDestroyerOfWorlds Mike ends up blowing up their planet]], leaving only the one behind to hang around with Pearl and Bobo. Allegedly, his species is just the brain, which his "host body" carries around in a salad bowl, but [[MST3KMantra this show being what it is]], the concept is only tangentially ever alluded to, and you may as well assume the guy in pale face with the robe is "Brain Guy".
* AchillesHeel: Turns out keeping your brain in a big, open salad bowl is kind of a crummy idea.
* AmbiguouslyGay: Aside from the TransparentCloset, he tends to be a little effete.
-->'''Observer''': ''[on [[{{Hamlet}} Fortinbras]]]'' He made ''me'' look butch.
* ButNotTooWhite: His stark clown-white makeup was eventually toned down as the series progressed -- he was in increasingly more scenes next to Bobo, and the crew found it hard to properly light the contrasting dark tones of the suit's fur while preserving detail on Bill's face.
* ButtMonkey: Even Bobo gets to mock him quite a bit.
* DitzyGenius: Theoretically omnipotent and omniscient... unfortunately, he's a complete wimp and sad sack with no initiative.
* {{Expy}}: Seems to be modeled after the psychic mutants from Film/BeneathThePlanetOfTheApes.
* HiveMind: According to Observer, his race is an interconnected neural net, which might explain the Power Creep Power Seep below.
* InsistentTerminology: Observer states he doesn't have a body. Except, you know, for the fact he actually ''does'' have one.
-->'''Observer''': ''[after being thrown onto a grenade to protect others]'' It's a good thing I don't have a body!
** Which leads to a weird situation in ''[[Recap/MysteryScienceTheater3000S08E20SpaceMutiny Space Mutiny]]'' when his body and brain being separated makes ''both'' a complete idiot with half their power.
* InTouchWithHisFeminineSide: And looks surprisingly decent in a nurse's outfit.
* {{Pacifist}}: Subverted. His race doesn't believe in war. They kill only out of personal spite.
* TheOmniscient: Claims to be this, but [[NotSoOmniscientAfterAll actions speak louder than words]]...
* OnlyKnownByTheirNickname: Mostly. Very few people ever call him Observer.
* OnlySaneMan: For instance, he's the only one who notices during ''Hobgoblins'' that Mike and the 'bots have replaced themselves with cardboard cutouts.
* OxymoronicBeing: The limitations of the supposedly all-knowing, all-powerful Observer species are made into a RunningGag of sorts -- their brains are claimed to be "entirely self-sufficient" but still require host bodies that may or may not exist, said brains are kept in jars (where they have a functional range of only 50 yards) rather than inside their heads, and their infinite intelligence can be hoodwinked by crude trickery or intimidated by physical threats.
* PlanetOfSteves: ''All'' of his species are named "Observer", which leads to this when they reunite!
-->'''Observer''': ''[sees Mike-Observer]'' Observer! ''[sees Paul-Observer]'' Observer!\\
'''Mike-Observer''': Oh, Observer...
* PowerCreepPowerSeep: Apparently, spending time with Pearl has weakened his powers. When confronted by other Observers, Observer said he'd blight Mike with his powers - and ended up giving Mike a new tie.
-->'''Observer''': ''[puzzled at first, then...]'' [[HandWave AHA! No one wants a tie for a present! Can't you see what a terrible gift that is?]]
* SufficientlyAdvancedAlien: Parodied. Once, Observer huffed at Pearl, "I'm not ''that'' omnipotent, Pearl!"
* TookALevelInDumbass: Though to a lesser extent than Bobo. Possibly justified, as it ''was'' the Bill Corbett Observer who was found wanting by the other Observers and his brain placed in the Enrichment Chamber, which Bobo confused for a refrigerator and subsequently carved up his brain for sandwich meat. Being separated from the HiveMind Observers dampened his powers as well, as noted by Mike-Observer.
* TransparentCloset: Inverted. Everyone ''but'' Observer are shocked by his CampGay behavior, such as dressing as a nurse or wearing drummer outfits. When he takes some condoms, he tells Pearl it's for his many ... ''[[BlatantLies lady]]'' [[HaveIMentionedIAmHeterosexualToday friends]].

[[folder:Kinga Clayton Forrester]]
->'''Played by''': Creator/FeliciaDay

The daughter of Dr. Clayton Forrester. She's following the footsteps of her father and grandmother in sending the most terrible movies possible to Jonah and the Bots.
* AudienceWhatAudience: Gets a little disturbed when Joel calls her a fictional character during a Website/{{Kickstarter}} video.
* BadBoss: She yells at [[TheFourthWallWillNotProtectYou Joel]] to get back to work, slaps her underlings if she doesn't think they're working fast enough, and is distinctly unconcerned about dangerous conditions and "supernatural manifestations" affecting her underlings in Moon 14.
* CompositeCharacter: In addition to taking traits from both Clayton and Pearl, her bio on [=mst3k=].com describes her as "equal parts Cruella De Vil and Kim Jong-il", and Joel Hodgson first conceived her by taking the villain from ''Film/TheSuperInframan'' and pasting Lucille Ball's head on her.
* CorruptCorporateExecutive: a third generation villain who wants to become Queen of All Media and eventually sell the ''Series/MysteryScienceTheater3000'' brand to Creator/{{Disney}} for a billion dollars.
* DaddysLittleVillain: Well, ''Grandma's'' Little Villain, at any rate. She [[WellDoneSonGuy really wants Pearl's approval]], but has some problems getting it.
* DisappearedDad: Presumably she became a Mad after the death of her father.
* EmbarrassingMiddleName: Clayton, after her father.
* EvenEvilHasStandards: She's a CardCarryingVillain, and willing to do business with Hitler--that is, ''Todd'' Hitler, a coffee brewer from UsefulNotes/SanFrancisco. But she draws the line at associating with ''Adolf'' Hitler or actual Nazis.
%%* EvilRedhead
%%* FieryRedhead
* {{Greed}}: Her primary motivation for restarting her father's experiment is to make it popular and sell it [[DisneyOwnsThisTrope to]] Creator/{{Disney}} for a billion dollars. She also frequently attempts to market other money-making endeavors and gain investors for her work, but these efforts never pan out.
* HilariouslyAbusiveChildhood: A joke in ''At the Earth's Core'' implies that she was raised by Pearl, who tried to abandon her multiple times. But Kinga just kept coming back.
* KickTheDog: Apparently the sight of cute animals fills her with the desire to punt them across the room. She invented Punt Bunnies specifically to indulge this.
* LegacyCharacter: Is proudly carrying on her father's and grandmother's legacy of trying to drive a guy in a jumpsuit insane with bad movies.
* MadLibsCatchPhrase: "Prepare to enter the nightmare-fueled world of !"
* MadScientistsBeautifulDaughter: Without a doubt the most physically attractive of the Forresters.
* MissingMom: Her mother's identity and whereabouts have not been brought up yet.
* TyrantTakesTheHelm: Apparently bought the rights for the show from Joel.
* TheUnfavourite: Initially Pearl doesn't seem to like her much; she intentionally tries to avoid meeting up with Kinga. Pearl seems to warm up to her in the season eleven finale though.
* VillainousCrush: Initially, she has [[LongDistanceRelationship an online boyfriend]], but he breaks things off when Kinga wants to see him in person. Then, she falls in love with Jonah Heston--or at least, falls in love with the huge ratings boost she'd get from marrying him.
* WhoNamesTheirKidDude: "Kinga"?
** [[SmallReferencePools It's Polish.]]
* WrongGenreSavvy: Kinga treats the new season as if it's still on Comedy Central or the Sci-Fi Channel, attempting to pull off ratings stunts so she can make it a ratings hit and sell it to Disney. As Max continuously points out, they're on Creator/{{Netflix}}, which doesn't run on those sorts of ratings. Not that she listens.

[[folder:TV's Son of TV's Frank (Max)]]
->'''Played by''': Creator/PattonOswalt

[[ExactlyWhatItSaysOnTheTin The son of TV's Frank]]. Like his father, he assists Kinga in torturing Jonah and the Bots with low-grade movies, as well as button-pushing.
* AffablyEvil: He mostly just follows orders and inherited the cheerful personality of his father. [[spoiler: He does unleash a monster that attacks Jonah in the season 11 finale, but his primary motivation is to stop Jonah and Kinga's wedding]].
** AmbiguouslyEvil: It's not made clear by the end if he's crestfallen that Kinga didn't react as he hoped, disappointed at how everything turned out, or [[spoiler:genuinely remorseful that he might've accidentally killed Jonah]].
* ButtMonkey: Much like his father, he gets little to no respect from the Forrester in charge.
* ExpositionFairy: He does the voiceovers during the ad bumpers, to give viewers info about Moon 13.
* FriendlyEnemy: He gets along well with Jonah and the bots for the most part. Jonah also makes a point to call him by his preferred name.
* GenerationXerox: Has the same build as his dad, the same hair (complete with a curl in the front), the same taste in black, double-breasted suits, the same good-natured dim-wittedness...
* IgnoredEnamoredUnderling: He's madly in love with Kinga. She treats him like some kind of furniture that occasionally talks.
* InsistentTerminology: He insists on being called TV's Son of TV's Frank. Kinga never complies and just calls him by his real name, Max.
* LegacyCharacter: Carrying on the Second Banana legacy of his father.
* ShoutOut: The fact that his real name is Max is a reference to ''Film/TheGreatRace'', where Professor Fate's minion, also named Max, often received the order, "Push the button, Max!"
* SuperGullible: Pretty much the only reason he didn't give the spirit of "Red Crow" (clearly Jonah and the bots in a wooden cut out) the keys to Jonah's ship was because Kinga intervened.
* VillainousCrush: On Kinga Forrester.
* YesMan: While the previous Mads' assistants typically vacillated between helpful and unhelpful (Pearl often had to threaten or coerce Bobo and Observer into helping her out if it didn't involve torturing their shared enemy Mike, and TV's Frank's relationship with Dr. F was bizarrely codependent and mercurial), Max is easily the biggest suck-up since Dr. Erhardt. The only thing about his job that he seems to dislike, apart from Kinga's coldness and abuse, is that he's treated like a common grunt and discouraged from fun things like hyping the movies' badness or bantering with Jonah and the Bots.

[[folder:Kinga's other minions]]
->'''Played by''': Rebecca Hanson

A clone of Pearl Forrester, graciously donated so the ''real'' Pearl wouldn't need to visit her granddaughter.
* CloneDegeneration: Implied. She moves very stiffly and she talks like a robot. [[SubvertedTrope Most of the time]]...
* ObfuscatingStupidity: In "Cry Wilderness", she acts like a normal person as soon as the original Pearl leaves, suggesting that she's just faking the Clone Degeneration.
* SeparatedAtBirthCasting: Synthia came about because Rebecca Hanson looks a ''lot'' like a young Mary Jo Pehl.
** In fact, at least one online outlet reviewing the series' trailer (in which Synthia makes a split-second appearance) assumed it ''was'' Mary Jo Pehl.
* TheVoiceless: In most episodes, she just shows up in the background and doesn't say anything.

->'''Played by''': Joel Hodgson

The guy in the hazmat suit who sends the movies up. He also manages the movie storage tanks in the even-lower basements of Moon 14.
* AdaptationInducedPlotHole: He helps the show avoid them, pointing out what happened in important scenes that were cut for time.
* CatchPhrase: "Movie in the hole!", and "This is Ardy, your maintenance man..."
* CreatorCameo: Which finally allows Hodgson to join his fellow ''Series/MysteryScienceTheater3000'' alumni who've played multiple characters throughout the series (he only played Joel Robinson during the series' original run).
* FacelessGoons: Wears a face-concealing hazmat suit at all times.
* ShoutOut: Ardy's latter catchphrase (listed above), mundane function, lackadaisical demeanor, and facelessness are partially inspired by [[Series/{{Rhoda}} Carlton the Doorman]], who also helped influence Joel's laid-back nature on the original show (and was briefly imitated by him in the ''Mitchell'' episode).
* SpellMyNameWithAnS: The end credits say his name is "Ardy", but the episode subtitles give it as "R.D."

!!!The Skeleton Crew

Minions in black-and-white skeleton outfits who play the show's theme music, wrangle dinosaurs, and fulfill Kinga's other, unknown whims.
* FacelessGoons: They wear skull face paint, and motorcycle helmets over it.
* HumanPopsicle: Kinga keeps them in suspended animation between episodes. [[TakeOurWordForIt Allegedly, it's a really horrifying process]].
* ShoutOut: They look just like the skeleton biker {{Mooks}} from the movie ''Film/TheSuperInframan''.
* SkeletalMusician: Based on what we see on-screen, their main role seems to be performing the show's original music.
* SuperSoldier: They're the results of Kinga's failed attempt to genetically engineer atomic supermen.
