History Characters / BackToTheFuture

Grandfather of Gerald Strickland and Marshal of Hill Valley in 1985.

* GoldTooth: Had a single gold incisor in 1955.

* ReasonableAuthority: He clearly doesn’t buy any of Edna’s accusations about Marty.

* ReasonableAuthorityFigure: If nothing else he is willing to intervene when he sees Biff about to beat up Marty, showing that if nothing else Mr. Strickland doesn't tolerate bullying.

!!Edna Strickland
->'''Voiced in the Creator/TelltaleGames series by:''' Rebecca Sweitzer (present time) and Shannon Nicholson (younger version)
Sister of Gerald Strickland. A CrazyCatLady Marty meets in 1986. Because Marty interacts with her and young Emmett in 1931 they both fall in love, this little mistake throws the timeline into jeopardy and prevents the events of the movie from ever happening.

* VillainyFreeVillain: He's a strict hardass, but aside from his survivalist mode and confiscating the almanac, he's hardly evil or malicious.

* CrazyCatLady: The original 1986!Edna and [[spoiler: Crazy, Old 1931!Edna]].

* AllThereInTheManual: [[Literature/BackToTheFuture George Gipe's novalization]] says that they're a part of a six-person cell, their leader is nicknamed "Sam", and one of their ranks is an ex-fashion model named Uranda.
* BigBadWannabe: They're murderous terrorists intent on building nuclear bombs, an agenda that could have ''far'' surpassed any of the Tannens in threat level. However their attempts to murder one single teen are completely haphazardous, with their vehicle and artilery blatantly unreliable, and after crashing they are never even heard from again. Had they not [[DirtyCoward cold bloodedly shot down a surrendering Doc]] just moments prior they could have passed as {{Ineffectual Sympathetic Villain}}s.

* UncertainDoom: [[spoiler:There's conflicting information about whether or not they survived their van crashing. The novelization says that the police show up shortly after they crash and take them into custody, but there's no confirmation of this in any other media.]]

'''Voiced in the Creator/TelltaleGames series by:''' Kid Beyond (original release), Creator/ThomasFWilson (2015 rerelease)
George [=McFly's=] boss in the original 1985 who constantly picked on George in high school in 1955. Thanks to Marty's intervention in his high school years, he becomes a humble auto servicer who would later use the [=Delorean=] to alter the timeline to his favour until Marty and Doc revert that timeline.

* ZeroPercentApprovalRating: Absolutely no one at school likes Biff due to his bullying and generally awful personality. Upon everyone finding out that he knocked Biff out cold, George instantly becomes popular among his classmates.
* AbusiveParents: He has become Lorraine's children's stepdad in 1985-A. A line from Lorraine implies he lets his goons hit her kids, he punches Marty in the stomach when he tries to stand up for his mother, and he threatens with cutting Lorraine's kids off when she threatens to leave him.
* ActuallyPrettyFunny: In the second movie, when his 2015 self goes to 1955 and overhears his younger self arguing with a mechanic over the cost of his car's repairs from the manure truck accident, he chuckles, remembering the incident with nostalgia rather than bitterness.
* AllGirlsWantBadBoys: Invoked. Biff insists on this while flirting with Lorraine on some occasions. Thankfully, she's not one of them.
* AMFMCharacterization: In 1955, he listens to Music/PerryComo on his way to the dance.
* ArchEnemy: To the [=McFly=] Family in general, but mostly Marty in the first and second movies.
* AttemptedRape: In Part I, he tries to have his way with Lorraine. Luckily, George showed up before Biff did anything to her.
* AxCrazy: When Biff goes on a tear, he takes abject glee in hurting people, be it running someone down with his car, AttemptedRape, or trying to break George's arm.
* BadBoss: He's George's supervisor in the original timeline, and practically the same bully he was to him in high school.
* BarbaricBully: Big (lampshaded), dumb (says certain things grammatically incorrect, although he's smarter than his grandson), and ObviouslyEvil (attempts to rape Lorraine in their high school years, as well as his old self going back in time to turn the present-85 into a hellhole), three out of three.
* BeingGoodSucks: Biff's redemption didn't last, as dealing with a psychotic grandson left him bitter and pining for a better life he felt entitled to.
* BerserkButton:
** He really hates manure. When Marty told him in 1985-A he heard about the manure incident in 1955 he seemed more angry about being reminded of it than confused of how Marty found out.
** He also doesn't like being compared to George [=McFly=]. As shown in 1985-A, when he [[DomesticAbuse slapped]] Lorraine for saying he's not even "half the man" George was.
* BigBad: In ''Part II''. His alteration of the timeline turns Hill Valley into a dystopia -- with him at the top -- that should be [[SetRightWhatOnceWentWrong set right]]. He's also [[TheHeavy a major antagonist]] in ''Part I'', but in this film, his bullying and jerkassery is only half the challenge Marty is faced with.
* BigStupidDoodooHead: His favorite insult is the supremely juvenile "butthead" well into his old age.
* BitchInSheepsClothing:
** The new "nicer" Biff that appears at the end of the first ''Back to the Future'' is pretty much an act given that he returns to being a massive {{Jerkass}} when he's an old man (in context, he seems ''really'' bitter about how Marty Sr. turned out). It's unknown if he's still this way in ''Part III'' after the timeline's fixed.
** The Biff of 1985-A cultivates a philanthropist image in his rise to power.
* BookDumb: He's not good at school, but as shown in ''Part II'', he's very good with cars, and in Part I, he has a reasonably successful auto-repair business.
* TheBully: Pretty much the go-to example in film. Biff is this to George, Marty, and Lorraine. In fact, he likes to push around ''everyone''. As the sequels and expanded media demonstrate, it runs in the family.
* BullyBrutality: Engages in this when he tries to run Marty into the back of a manure truck. He also tries to grope and rape Lorraine, and when George intervenes, Biff tries to break George's arm.
* BullyTurnedBuddy: PlayedWith, as it's only in the "good" version of 1985 that he became friends with George, after George stood up to him. Reformed 1985 Biff seems to be on (somewhat) friendly terms with Marty: in the beginning of Part II he's eager to show Marty his new custom-made matchbooks, but knowing the old Biff all too well, Marty seems to take this with cautious acceptance.
** Even in the original 1985 Timeline, it seems that Biff and George are probably the closest thing to best friends that they have along with workmates. Unfortunately they are just continually playing out their toxic dynamic of bully and victim from High School as middle aged men. George KNOWS Biff is an asshole and his life would be much better off without him but doesn't have the guts to stand up to him.
** [[spoiler:This is further played with in the video game, implying that while his bullying nature is actually genetic in some ways, it's also partly due to his circumstances. After Marty and Doc's adventures in 1931, Biff is no longer an unwanted child raised by his grandmother. His estranged, criminal father Irving "Kid" Tannen cleans up his act after falling in love with Edna Strickland in jail and manages to become a grounding and positive influence in Biff's life along with his new wife. The resulting version of Biff is a lot more cheerful and is on much better terms with George and his family than his previous iterations.]]
* TheCaligula: In 1985-A, his building is labeled with a gigantic likeness of him with giant neon letters that say "BIFF'S." He also spends most of his time yelling at people, and literally getting away with murder by buying out the corrupt police force. And the only reason he's as powerful as he is was because his future self literally handed him an almanac that allowed him to win at gambling at any sporting event he wants.
* CannotTellAJoke: Biff is constantly, err, [[{{Pun}} biffing]] his attempts at wordplay with lines like "Why don't you make like a tree and get out of here"[[note]]It's "leave", you idiot! "Make like a tree, and ''leave''". You sound like a damn fool when you say it wrong![[/note]] and "That's as funny as a screen door on a battleship!"[[note]]"Screen door on a ''submarine'', you dork..."[[/note]] Presumably everyone is too afraid of him to correct him. He is [[LampshadeHanging berated]] for this by his [[IHatePastMe older self]] in the second movie.
* CantGetAwayWithNuthin: In the altered 1985, where he's rather submissive to George, he can't get away with putting on only one coat of wax on any cars.

** "Hello! Hello! Anybody home?! Hey, think, [=McFly=], think!"
** "What are you looking at, [[CatchphraseInsult Butthead]]!"
** "Hey [=McFly=]!"
** "Why don't you make like a tree [[{{Malaproper}} and get out of here]]?"
* CessationOfExistence: Old Biff fades into nothingness the moment he travels back to 2015, due to altering his own past in such a way that he wouldn't live as long. This should have caused a temporal paradox, but the consequences of his actions are thwarted before any possible cosmic anomalies could occur.
* CharacterCheck: Biff seemed to have genuinely reformed in the improved timeline, but when he sees Marty and Jennifer get into a flying Delorean, something in him clicks and he shows up in the future having undone all of his character development.
* ChildHater: As a teenager he stole a ball from some children and threw it onto a roof. Marty is a downplayed example, as despite being old enough to drive he's still 17 and thus a minor.
* CorruptCorporateExecutive: In 1985-A, as the founder of Biffco. He apparently has a head for business, as he's basically a small business owner in the 'fixed' 1985 timeline and is George's supervisor at some sort of office business in the 'starting' 1985 timeline, meaning he's this trope in both of the 'bad' 1985 timelines seen in the films (though he's a mere grown up bully in the 'starting' timeline instead of a crime boss).
* DeadpanSnarker: Very rarely, if ever. Especially [[OlderAndWiser Old Biff]] who does not really [[IHatePastMe like his past self]].
-->''[After 1955 Biff verbally and physically harasses Lorraine and yells how he'll marry her one day]''\\
'''Old Biff:''' You always did have a way with women.
* DemotedToExtra: After being the central antagonist of the first two films, he only appears briefly near the end of the third film in a fairly inconsequential role. [[JustifiedTrope Justified]] in that the majority of the film took place decades before he was even born.
* DidntThinkThisThrough: He steals the [=DeLorean=] in the ride version to travel through time and profit. Even though he knows cars, he doesn't know how to ''fly'' them. Cue Biff nearly getting killed in the prehistoric era.
* DirtyCoward: Biff's bullying is largely borne from thinking he has the upper hand on those he picks on. Standing up to him or proving you're able to fight back tends to make him back off. After George knocks him out, Biff is implied to have left him alone afterwards.
* DisproportionateRetribution: Biff really takes retaliation too far.
** His response to Marty standing up to him in 1955 was to run him down with his car.
** George punched him out in high school for threatening Lorraine. In the bad timeline 1985-A, Biff used his connections with the police to kill George personally, cover up the crime, marry Lorraine, and make her life hell.
* DomesticAbuse: In the alternate timeline in Part II, he is horrifically abusive towards Lorraine. He's physically aggressive with her, he harms her children in front of her, and it's implied he made her do things like make her get breast implants. He also uses threats to keep her under his control like threatening her children if she ever tries to walk out on him.
* EasilyForgiven: Biff forces himself in Lorraine and attacks George. Yet in the altered 1985, both of them allow him into their lives as a sort of family friend.
* EntitledToHaveYou: In 1955 he believes wholeheartedly that Lorraine is "his girl", regardless of how she feels about him. This culminates in his attempt to rape her at the Enchantment Under the Sea dance. In the altered version, he ''murders'' George and threatens to ruin her children to keep Lorraine under his thumb.
* EvilIsPetty:
** Exhibit A -- Stealing a ball from some neighborhood kids and [[ThrewMyBikeOnTheRoof hurling it onto a nearby roof]]. And then he strolls away cackling to himself.
** It's obvious that he doesn't like Lorraine for her personality; at best he'll cop a feel to her dismay. Yet in 1985-A he forced her to marry him and get plastic surgery, and threatens her kids to make her comply.
** In the alternate present, we see a headline describing George's murder; Biff, the actual gunman, crows that the police would never arrest him. The article explains that George was headed for a meeting to protest the environmental policies of Biffco.
* EvilLaugh: ''Icing on the cake.''
* FatalFlaw: His wrath and need to bully others gets him because it inevitably makes people hate him.
** His abuse of Lorraine is what causes George to finally snap and knock him out.
** [[spoiler: Per WordOfGod, Biff's abuse of Lorraine finally causes her to finally kill him in revenge]].
* FauxAffablyEvil: He acts like a guy [[VitriolicBestBuds good-naturedly ribbing his buddy]] when bullying George, but is in fact a sadistic asshole who has no problem forcing himself on women.
* {{Flanderization}}: The ''Biff to the Future'' comic drastically ramps up his {{Malaproper}} traits, to the point where he mangles at least one phrase or adage on every single page.
* FreudianExcuse: His [[TheUnseen grandmother]] sounds like a case. In the Telltale game, his father is revealed to be a notorious bootlegger.
* FromNobodyToNightmare: Once he gets his hands on the Grey's Sports Almanac from the future in the second film, Biff goes from a bully to a murderer, a {{Domestic Abuse}}r (toward's Marty's mother, no less), and CorruptCorporateExecutive. Thanks to him, Hill Valley is overrun with crime. His influence extends far beyond the town, as he is implied to be responsible for the legalization of gambling as well as allowing Nixon to stay in office for ''four'' terms.
* FutureLoser: The altered timeline had him waxing cars, most often for the [=McFly=] family, in contrast to his supervisor job in the original timeline. Seems to be aware that he's this by 2015.
* GrumpyOldMan: His 2015 self, which proved he never stopped being a jackass.
* TheHeavy: In Part I, half the conflict is getting Marty back to 1985. The other half is the 1955 Biff bullying Marty's father George, which is a more personal conflict that threatens Marty's existence since George might not get the guts to court Lorraine, marry her and sire Marty and his siblings, causing them to be [[{{Retgone}} erased from existence]].
* HeelFaceTurn: PlayedWith. Biff does become nicer in the altered timeline, but it is questionable whether he has genuinely turned over a new leaf or is simply behaving in a sycophantic manner to a wealthier and more confident George. His 2015-self bullies (who he believes to be) Marty's son with his cane, but he also doesn't like his bullying grandson Griff, is more chill about the manure incident than annoyed, and is ashamed with how stupid his younger self was, proving he's gained ''some'' wisdom, if not morals.
* HeKnowsTooMuch: [[spoiler:The elderly Biff left some other instructions for his 1985-A self: If anyone (specifically Marty or Doc) comes to him asking about the almanac, kill them.]]
* HeldBackInSchool: Despite being a year older than George and Lorraine, Biff was in the same classes as them. The 1985-A explains this by saying that he took a year helping the high school football team.
* HiddenDepths: Old Biff is a grouch, but he remembers the manure incident with amusement rather than shame. This implies he did mature a little bit.
** His teenage self was also smart enough to switch the dust jacket on his Almanac with a girly magazine to keep it from being stolen, which is a far cry from the dumb muscle he appeared to be back then.
* HighSchoolRejects: In the altered timeline, his life after high school went nowhere and he is stuck in a humiliating position, washing the [=McFly=] family's cars.
* IHatePastMe: The elderly Biff is quite embarrassed about how dimwitted the younger Biff is.
-->'''Old Biff:''' It's '''LEAVE''', you idiot! "Make like a tree and ''leave''". You sound like a damned FOOL when you say it wrong!
* IHaveYourWife: The gist of his blackmail on Lorraine in 1985-A. If she tries to leave, he'll cancel Linda's credit cards and stop covering her debts, have Dave's probation revoked, and get Marty (plus Linda and Dave, if he feels like it) jailed.
* {{Jerkass}}: He's has a callous personality up until George stands up for himself, anyway. And he seems more bitter than jerkass in 2015 - given the opportunity to go back in time, he opts to make himself rich rather than do anything to the [=McFly=] family. [[spoiler:While he does make himself rich, he turns the town into a hellhole and evidently gets himself killed years before 2015.]]
* JerkassHasAPoint: In ''Part II'', the scene where he punches Marty in the stomach after he tried to stand up for his mother is obviously meant to be a KickTheDog moment, but he does call out Marty's FatalFlaw.
-->'''Biff:''' Always a little hot-headed, huh?
** Also He says to George "Don't be so gullible. [=McFly=]". While said in a mocking tone, it is good advice after all, but he sadly [[HypocriticalHumor doesn't follow it himself since he falls for Marty's]] "[[LookBehindYou Woah, woah, Biff. What's that?]]" trick.
* JerkassToOne: He's especially nasty to George, with his bullying dating back to 1955.
* JerkJock: 1955 Biff is a textbook example.
* KarmaHoudiniWarranty: In the original timeline, he got away with bullying George well into adulthood.
** In the first movie, George gives Biff the punch he so richly ''deserves''. In the revised 1985, he is reduced to a pathetic mechanic who cowers before George.
** [[spoiler: In 1985-A, he would get away with murder and years of domestic violence toward Lorraine. However, Lorraine would eventually snap and kill him in the 1990s]].
* KarmicDeath: [[spoiler: Thanks to a deleted scene, he gets two for the price of one. In Part II, Old Biff gives the almanac to his 1955 self to create a future where he's top dog, but upon his return, he doesn't live to enjoy the fruits of his efforts; in the newly-created timeline, Biff dies at Lorraine's hands in the 1990s after abusing her for years, which means 2015 Biff disappears into thin air.]]
* KnightOfCerebus: Single-handedly responsible for bringing about the BadFuture of 1985-A in ''Part II''.
* LargeAndInCharge: Biff is 6'3" and the leader of his GangOfBullies.
* LargeHam: For a bully and a general pain in the rear, he's rather (melo)dramatic in talk and/or action. Even his 1985-A self is just as over-the-top as the original.
* {{Malaproper}}:
** In ''Part II:''
--->'''Young Biff:''' ''[to old Biff]'' Now why don't you make like a tree and get outta here?!\\
'''Old Biff:''' (''[[[DopeSlap slaps young Biff]]]'') It's "LEAVE", you idiot! "Make like a tree and ''leave''". [[IHatePastMe You sound like a damned FOOL when you say it wrong!]]
** Also in ''Part II'':
--->'''Biff:''' That's about as funny as a screen door on a battleship.\\
'''Marty:''' ''[hiding in Biff's car]'' Screen door on a ''submarine'', you '''dork'''...
** And in ''Part III'', we find out that it runs in the family:
--->'''Buford:''' I'll hunt you and shoot you down like a duck!\\
(''{{Beat}}'')\\
'''Buford's Henchman:''' It's "dog", Buford, "shoot him down like a dog".
* ManChild: As an adult in the original timeline, he acts ''exactly'' like his teenage bully self from 1955, having no reason to ever mature; he forces George to do his work and takes advantage of him. In ''Part II'', [[spoiler:this crosses over to PsychopathicManchild in 1985-A when he's still just as bratty and immature, but now has the wealth and power to get everything he wants. The original Biff never actually killed anyone (though he did try to run Marty down with his car, ''twice''); 1985-A Biff has no misgivings and demonstrates it.]]
* MilesGloriosus: For a sadist whom everyone was afraid of, he had a ''really'' bad glass jaw.
* MoneyIsNotPower: [[spoiler: According to WordOfGod, Lorraine would've finally snapped and killed him in the 1990s, showing that wealth would not have made him invincible]].
* MoralPragmatist: The "reformed" Biff might have given up being a bully because he can't threaten people anymore rather than any shame or maturity. The Old Biff seems more exasperated with his younger self than ashamed of his cruelty.
* MurderTheHypotenuse: [[spoiler:In 1985-A, he kills George [=McFly=] in 1973.]]
* NeverMyFault: He totals the [=McFly=] car while illegally drinking behind the wheel, and blames George for it because the latter never told him it had a blind spot.[[note]]It's common knowledge that ''all'' cars have blind spots[[/note]] In Part 1, he blames ''Marty'' for wrecking his car and getting it covered in manure, and in Part 2 he insists the mechanic pay for the damages.
* NiceJobFixingItVillain: In the first movie, Marty's [[FakeDangerGambit plan to pretend to be sexually assaulting Lorraine so George can save her]], doesn't go well because Lorraine actually ''wanted'' to jump Marty, and Marty got disgusted by it. It's only when Biff shows up and actually tries to rape Lorraine that George gets a real chance at saving the day and finally [[TheDogBitesBack standing up to him]].
* NotAMorningPerson: Biff is implied to be this. Whenever George offers to go to Biff's home with the reports for Biff to copy and pass them as his own, Biff tells George not to show up too soon for this very reason.
* OhCrap:
** He and his gang have a collective "shit!" when they realize his car is headed straight towards the manure truck.
** He has this expression on his for a split second when he sees George's expression before being knocked out in one punch.
* OlderAndWiser: 2015 Biff. He formulates a surprisingly effective plan to make his past self rich, ''after'' listening to Doc talking about the risks of meeting an alternate self, and even figures out how to make the time machine work. [[spoiler:The plan, however, firmly wipes out his OlderAndWiser trait by having his 1985-A self retain a childish temper and ultimately die well before 2015, thereby erasing old Biff from existence until Marty sets things right.]] He's also become more amused than annoyed over the "manure" incident and is clearly ashamed of how much of a blockhead his 1955 self is.
* OurFounder: Has a wax statue of himself standing in 1985-A's museum.
* OutdatedOutfit: In 1985-A, he and his gang seem to fit in more with the TheSeventies than TheEighties.
* PetTheDog: Biff seems genuinely happy that George got a novel published. Judging by the way he excitedly runs in with the first editions, it's clear that he had been eagerly anticipating the books for awhile along with the family.
** Though he does so in his usual surly way, he's quick to confront what he believes to be a stranger (actually Marty in a cowboy outfit) messing with Marty's truck.
* PinkIsErotic: In 1985-A, Biff seduces women in a pink, purple, and red home, owns pink towels, and other pink decorations. Marty confronts him while he's in a jacuzzi with 2 other women.
* PragmaticVillainy: 1985-A Biff does share his wealth with Lorraine-A and her children when he marries her...purely so he can use the threat of cutting them off to keep Lorraine in line.
* RaisedByGrandparents: Teenage Biff lives with his grandma with no sign of parents, and she doesn't seem to be a particularly nice person, either.
* ReformedBully: In the altered timeline, Biff being under George's thumb has made him give up his meanest habits. However, him calling Marty "butthead" before he recognized him in the third film -- though admittedly in response to what appeared to be someone stealing his cleaning supplies, and while dressed in a ridiculous outfit to boot -- and the behavior of his older self in the second might cast doubt on whether he's reformed or just scared of George.
* ReformedButNotTamed: In the first film, it's implied Biff is willing to stiff George on a waxing job (until George pushes the issue), and in the third film, he gets aggressive and yells "Butthead" at Marty when he thinks he's some stranger stealing his cleaning supplies. If Biff has genuinely reformed then it shows he still hasn't fully lost his edge.
* {{Retgone}}: A deleted scene from ''Part II'' shows Old Biff fading away when he returns to 2015. [[spoiler:1985-A Lorraine apparently shot him some time in the mid-90s.]]
* RetiredMonster: It's heavily implied his altered version isn't a much better person, and that his kindness is just obsequiousness to his wealthier and more successful former punching bag. His 2015 version is a bitter grouch, albeit one who more or less keeps to himself. Even then, when Old Biff gets the opportunity to restore his younger self to power, he doesn't hesitate to take it.
* TheSociopath: He's pretty much the most monstrous character in the series; he has little to no inhibitions and he would do terrible things if he thought he could get away with them. In the first film, he harasses his classmates, tries to straight up murder 'Calvin Klein' with his car (in public no less) and later tries to rape Lorraine. In the second film, in the alternate timeline he murders George, abuses George's family for twelve years, and once again tries to murder 'Calvin Klein' with his car (and enjoys it even more this time).
* SchoolyardBullyAllGrownUp: In the original timeline, he's still at it, holding power over George. In 1985-A, he has power over Hill Valley, as well as California itself. The fixed timeline subverts this, to the point that George apparently trusts him to do a good job... eventually.
* ScrewTheRulesIHaveMoney: In 1985-A.
-->'''Biff:''' Kid, I ''own'' the police.
* SmugSnake: In 1985-A, he may have money, but that hasn't improved his intelligence and cunning one bit. Despite being armed, he very easily loses the Alamanac to Marty.
* ThinSkinnedBully: In the original timeline at the start of the first movie, Biff is a bully of Marty [=McFly's=] father from his college years, that continues to demean him in the present. When George stands up for himself and punches Biff out for trying to date rape Lorraine, he never bullies him again and ultimately becomes submissive to George in the present day.
* TimeTravelingJerkass: Once he gets his hands on Grey's Sports Almanac in 2015.
* TookALevelInJerkass: One would think the loutish bully who forced himself on Lorraine couldn't get any worse. But with money and power his other versions didn't have, 1985-A Biff goes from hoodlum to psychotic tyrant and wife-beater.
* TookALevelInKindness: It is possible that the altered Biff is a much nicer man, but it could be just an act. Regardless he sees to have given up his bullying ways.
* {{Trumplica}}: WordOfGod says the 1985-A version of Biff was inspired by UsefulNotes/DonaldTrump. That version of Biff is a billionaire celebrity with strong political connections and media presence, wears his blonde hair in a conspicuous combover, has loud taste in fashion and home decor, lives in a Vegas-style skyscraper, has a massive ego, casually objectifies women, and sustains his wealth and power through unethical business practices. The portrait in Biff's office was even based on one of Trump.
* TyrannicalTownTycoon: Becomes a tyrannical billionaire in 1985-A, making Hill Valley akin to [[Film/ItsAWonderfulLife Potterville]].
* UngratefulBastard: In the ride, after riders bump his car in the prehistoric era and send him back to the present, his response is "You saved my life...Buttheads!"
* VillainousBreakdown: After the second time, he crashes into a manure truck. He screams about how he hates manure and looks like he's about to ''cry''.
* VillainousCrush: For Lorraine. Taken to disturbing levels in the second film, and this is after the AttemptedRape which is still in play in 1955-A. Even the 2015 version has lingering "feelings" for her, as he told Marty (masquerading as his son Marty Jr.) "Say hello to your grandma for me."
* VillainWithGoodPublicity: In 1985-A, he's even got his own museum dedicated to his life story.
* VillainousLineage: Descended from an outlaw, he's pretty much more of the same. No word about how his son turned out, but his grandson Griff's at least as bad as he ever was if not more. And in the game, it's revealed that his father was a notorious bootlegger.
* VileVillainSaccharineShow: Downplayed in ''Part I'', in which his only two not PlayedForLaughs KickTheDog acts were trying to run over Marty with his car and attempting to rape Lorraine, nearly breaking George's arm when he stands up to him. Played straight in ''Part II'' in 1985-A, when he becomes a CorruptCorporateExecutive who is an {{Domestic Abuse}}r, turned Hill Valley into ''Hell'' Valley and [[spoiler:murdered George [=McFly=] in cold blood]]. Even for a science fiction adventure comedy trilogy it is, Biff in this alternate timeline had become the darkest antagonist of the series.
* WickedStepmother: He becomes a gender-flipped version of this in 1985-A. Wicked doesn't even ''begin'' to describe how cruel he is to Marty.
* WouldHitAGirl: In the first film, he pushes Lorraine to the ground, and in the alternate 1985 of ''Part II'', he abuses her along with Marty, among other things making her get breast implants.
* {{Yandere}}: He's an ''incredibly'' unpleasant version of this trope to Lorraine: In 1955, he sexually harassed Lorraine in broad daylight and nearly rapes her at the prom, and in 1985-A he murders George and threatens to ruin the rest of Lorraine's children if she leaves him.
* YouKilledMyFather: [[spoiler:He killed George, Marty's father, in 1985-A. Lorraine avenges George by shooting him in turn]].

[[caption-width-right:275: ''"Hey, Gramps, I told you two coats of wax on my car, not just one! GRAMPS! What the hell am I paying you for?!"'']]
->'''Played by:''' Creator/ThomasFWilson\\
'''Dubbed in French by:''' Creator/RichardDarbois
Grandson of Biff Tannen who leads a GangOfBullies in 2015.

* AxCrazy: He's far more unhinged than Biff was and even quicker prone to violence. To quote Emmet, "He's got a few short circuits in his bionic implants." Best exemplified by his version of the "your shoe's untied" gag: while Biff would merely lightly smack the person in the face, Griff outright ''punches'' Marty Jr.
* BatterUp: He attacks Marty with a metallic bat. He even says the TropeNamer BatterUp when he attacks.
* TheBully: Like grandfather, like grandson. He notably spends his brief amount of time pushing Marty's future son around and even bullies his grandfather.
* CessationOfExistence: Implied to have happened when old Biff went back in time. Old Biff's biography lists a series of celebrity women among his conquests, implying he never settle down with whomever Griff's grandmother was. Given their mutual hatred of each other, Old Biff likely wasn't too bothered by this casualty.
* CyberneticsEatYourSoul: Doc warns Marty that Griff's "bionic implants" make him unstable. We're never given much of an idea as to what these implants are, but sure enough, Griff is unnaturally twitchy, constantly visibly stressed, and even more aggressive than Biff.
* {{Cyborg}}: He has several illegal "bionic implants" installed in his body, giving him the ability to make himself even taller over Marty and even NoSell his "what's that!" punch by automatically blocking it. It makes him an even more violent and imposing bully than Biff was, leaving poor Marty Jr. helpless. It doesn't help him win against the GuileHero Marty Sr., though.
* EqualOpportunityEvil: Unlike his ancestors, whose GangOfBullies only comprised of white guys, his has an [[AsianRudeness asian guy]] and [[DarkChick a girl]].
* HeelFaceTurn: Played with. In the comic, he appears to have eventually traded in his criminal career for law enforcement, but it turns out he was brainwashed into it. That said, he does attempt to follow the rules -- if only because he's broken so many of them that he's already on thin ice -- [[ItMakesSenseInContext and initially only opposes Marty and Doc]] [[InspectorJavert because they were suspected criminals]]. But eventually his vices are too much to keep restrained, and he devolves back into the violent thug he was first seen as anyway.
* IdenticalGrandson: He looks exactly like Biff in his younger days.
* NeverMyFault: Despite being obviously guilty of causing mayhem, when he gets arrested he indignantly declares "I was framed."
* NoIndoorVoice: While Biff can at least tone his voice down sometimes, Griff just shouts pretty much every word he says.
* PutOnAPrisonBus: Griff and his GangOfBullies are last seen being arrested after their chase against Marty ends with them crashing their hoverboards into the courthouse. The newspaper confirms their arrest.
* RabidCop: In the further future seen in the comics. As a cop, he's under strict cybernetic control, but his AxCrazy tendencies, love of MoreDakka and frothing hatred of [=McFlys=] eventually lead to him demolishing half the city just to take down a couple of perps, and ending up in cuffs (again) himself.
* SmallRoleBigImpact: He only appears and is dealt with in the first act, but it's his actions that kick off Marty and Doc's trip to 2015, which in turn kicks off the rest of the film after Marty discovers the almanac.
* SpikesOfVillainy: Griff's shoes have massive silver spikes that make his feet resemble a rhino.
* StarterVillain: He's the main villain of the first act of ''Part II'', but is arrested at the end of that and his grandfather takes over as the true villain in the film.

[[folder:General Beauregard Tannen]]
!!General Beauregard B. Tannen
->'''Voiced in the Creator/TelltaleGames series by:''' Owen Thomas
The father of Buford and great-great grandfather of Biff. During the Civil War, he was a general for the Confederate Army. At some point after the war, he moved to Hill Valley to build a saloon. In an alternate timeline, his saloon was burned down by a time traveling Edna Strickland along with the rest of Hill Valley.

* JerkassHasAPoint: By the law of the time, Beauregard's business is completely legal and has every right to shoot [[spoiler:Edna]] for breaking and attempting to burn his property.
* JerkWithAHeartOfGold: A Tannen is a Tannen and Beauregard is just as much a jerkass like the rest of his family though he has his morals. Other than making truce with a Union General during the Civil War, his reason for opening a saloon other for money is also to provide the towns people a place they can enjoy after a day of hard work.
* MythologyGag: Beauregard previously appears in the [[WesternAnimation/BackToTheFuture animation series]].
* WhiteSheep: Downplayed. He is a murdering asshole like the rest of his family, but he at least doesn't like shooting women. Of course that doesn't matter if they're trying to destroy his livelihood.

->'''Played by:''' Creator/ThomasFWilson\\
'''Dubbed in French by:''' Creator/RichardDarbois
An outlaw who terrorized Hill Valley in 1885 and Biff's great-grandfather.

* BerserkButton: Calling him by his nickname "Mad Dog" has apparently been Buford's for a long time as the moment Marty says it in the Palace Saloon, [[MassOhCrap every single person in the saloon either silently runs away or makes themselves scarce]].
* BigBad: The main antagonist of the third film. He killed Doc in one timeline and preventing Doc's death at Buford's hands is the reason why Marty travels to 1885.
* ChekhovsGunman: He's first mentioned in the video playing in Biff's Museum in 1985-A.
* DisproportionateRetribution: Originally, he shoots Doc in the back over a matter of 80 dollars, involving a horse that threw a shoe (which Buford shot) and the bottle of whiskey that broke as a result. He also shot a newspaper editor who printed an unfavorable story about him in 1884, which made everyone stop keeping track of his kills.
* DoNotCallMePaul: Inverted. He absolutely ''hates'' being called by his nickname "Mad Dog Tannen".
* TheDreaded: He ''terrifies'' the people of 1885 Hill Valley. So much so that the newspapers stopped keeping track of all his kills after he'd shot an editor who printed an unfavorable story about him.
* EarlyBirdCameo: Is briefly shown in the second movie by way of a history lesson on the Tannen family.
* EvilHasABadSenseOfHumor: He thinks hanging Marty and later shooting him are funny.
* EvilWearsBlack: In keeping with old-time Western films, Buford wears an all-black suit in contrast to the heoric characters who all wear lighter shades.
* {{Expy}}: Of [[Film/TheManWhoShotLibertyValance Liberty Valance]]. This was deliberate on Wilson's part, right down to calling Marty "dude".
* HairTriggerTemper: One of the reasons he's nicknamed "Mad Dog", and a major reason why everyone is scared of him.
* HistoricalHeroUpgrade: InUniverse. In the 1985-A of the [[Film/BackToTheFuturePartII second movie]], where his great-grandson Biff Tannen made himself a billionaire, the museum in his casino portrays him as a much more heroic figure than he actually was.
* IdenticalGrandson: A bit tricky to pin down the usual features of a Tannen through that mustache, but he has 'em.
* InTheBack: How Buford kills Doc in the original timeline. In a deleted scene, Buford does the same thing to Marshal Strickland when the marshal tries to stop him as he heads into town to duel with Marty.
* {{Jerkass}}: Well, he's a Tannen. What else would you expect at this point?
* KickTheDog: Shooting a man dead in a fair duel is one thing. Shooting him dead after he's taken off his gun and wants to resolve the situation otherwise and gloating about it after? That's just low. Even his gang looks shocked.
* KnightOfCerebus: Naturally, being an ''actual'' gun-toting outlaw rather than just a school bully, he's much more dangerous than the average Tannen and rivals 1985-A Biff as a threat. He almost successfully ''hangs'' Marty after their version of the "bar chase" scene and much of the third movie is spent trying to alter several futures in which he shoots either Doc or Marty to death.
* {{Malaproper}}: "I'll hunt you and shoot you down like a duck." "It's dog, Buford."
* NamesToRunAwayFromReallyFast: "Mad Dog" Tannen...you think this is a bad guy?
* NeverMyFault: [[VillainousLineage Just like his descendant]]. Buford shot his $75 horse dead, but blamed Doc for it because the latter fitted the animal with a shoe that was thrown off. And which Buford didn't pay him for.
* PoliticallyIncorrectVillain: "He once bragged that he'd killed 12 men, not including Indians or Chinamen."
** He also doesn't seem to like Irishmen, if telling Seamus never to come to the saloon is anything to go by. This marks the beginning the [=McFly=]-Tannen feud.
* PutOnAPrisonBus: [[spoiler:He and his henchmen are all arrested]] after Marty [[spoiler:beats up Buford]] at the end.
* VileVillainSaccharineShow: While Biff is a confirmed murderer and cheat, most of the damage of his antics in ''Part II'' is just a side effect of his ignorant, narrow-minded selfishness. Buford, however, is a career criminal who revels in violence and actively enjoys killing, to the point where he revels in hanging Marty and slowly suffocating him for accidentally using his hated nickname and muses about how a bullet from his Derringer could take days to agonizingly kill Doc.
* VillainWithGoodPublicity: Retroactively in the alternate 1985. The Biff Tannen Museum paints him as an outlaw of intrigue and derring-do in the vein of Jesse James rather than the ruthless bully and murderer he'll show himself to be in the next film.
* WouldHarmASenior: Before Marty got involved, he shot Doc (who's currently in his mid-sixties) with a derringer, causing him a slow and painful death. The reason for it? Doc refused to pay him $80 after a horse he had shod threw a shoe and broke a bottle of whiskey, because Buford had never paid him for the job in the first place. In the new timeline, he attempts to kill him multiple times.
* WouldHitAGirl: After Clara kicks him for making lewd comments about her, he shoves her, knocking her down. This rouses Doc's ire considerably.

[[folder:Kid Tannen]]
!!Irving "Kid" Tannen
->'''Voiced in the Creator/TelltaleGames series by:''' Owen Thomas
Biff Tannen's father and a famous mob boss in 1931's Hill Valley. The owner of the Speakeasy that was razed the same year.

* AffablyEvil: Unlike Biff, Kid seems to have a more reasonable side to him, such as when he turns down Marty's request if he could deliver soup from him so to not give Edna competition. Another example has him giving some of his peanuts to Marty after the latter asks for some.[[note]]Of course, Marty asks for some so he can snatch Artie's hat (that was holding said peanuts) from him.[[/note]] He also is a man of his word, as he keeps his promise to not kill Artie after Trixie begged him not to, and even must have allowed them to get together eventually, seeing as Marty's family line still exists in the altered timeline from Episode 2 of the Game.
* BreakTheHaughty: [[spoiler:His time in prison reduced him to a kind old man married to Edna.]]
* DiscOneFinalBoss: He's kinda like the BigBad in episode 1 and 2, but his role is limited to cameos in the other episodes.
* FauxAffablyEvil: Puts on a charming social front, but cracks jokes about the people he's killed.
* {{Jerkass}}: He's a Tannen, what would you expect?
* LikeFatherLikeSon: He's pretty much Biff as a gangster.
* LoveRedeems: [[spoiler:He reforms from his evil ways in the end of Episode 5. See Edna's entry for more.]]
* {{Malaproper}}: "Make like a tree and die, rat!"
* OppositesAttract: [[spoiler:With Edna Strickland.]] He's a womanizing trouble-maker while she's a HeroicWannabe trying to bring order. [[spoiler:They end up happily married and even manage to reconnect with Kid's estranged son, Biff.]]
* ParentalAbandonment: Has Biff out of wedlock with a woman named Myra Benson. They get married strictly for appearances sake, dump Biff on his grandmother, and then part ways as soon as they can. [[spoiler:After Kid's reform, he comes back for Biff (most likely due to Edna's insistance or out of regret when he actually learns what [[HeelFaceTurn love feels like.]]) and manages to reconnect with him, forming a newer, happier Tannen family with Edna.]]

The Vice Principal of Hill Valley High School.
----
* BaldOfEvil: Granted he's not so much evil as much as he's a strict jerk, but he's completely bald in 1985, and when Marty is in 1955, he lampshades Strickland's male-pattern baldness.
-->'''Marty:''' Jesus, didn't that guy ''ever'' have hair?
* CatchphraseInsult: "Slacker!"
* DeanBitterman: Even in the 50s he was against his students' wild side.
* EmbarrassingOldPhoto: In the game, Marty finds an old photo of him as a child -- dressed like a girl -- in his sister Edna's apartment.
* FunHatingConfiscatingAdult: His name is probably an inside joke on the word 'strict'.
* FutureBadass: In the crime-ridden dystopian future of the second movie, he has become an embattled survivalist who semi-successfully defends his home against the heavily armed gangs who plague that version of Hill Valley.
* HairTodayGoneTomorrow: Averted. He's down to the last few dregs of his hair in 1955 and completely bald in 1985. Played for laughs with his great-grandfather who had extremely long hair. He's shown to have a full mane of blonde hair in 1946 in "Biff to the Future".
* INeedAFreakingDrink: In 1955 at least, he kept a bottle of liquor concealed in his office.
* {{Jerkass}}: He is hardly a pleasant fellow.
* JerkassHasAPoint: He tells [[ButtMonkey George McFly]] to [[GrewASpine shape up]].
* MeaningfulName: Strickland. He's really strict.
* ReasonableAuthorityFigure: If nothing else he is willing to intervene when he sees Biff about to beat up Marty, showing that if nothing else Mr. Strickland doesn't tolerate bullying.
* TookALevelInBadass: In 1985-A. He became a shotgun-wielding survivalist because of the collapse of civilization in Hill Valley. This is presumed to be stemmed from his military combat training during UsefulNotes/WorldWarII, as shown in an episode of [[WesternAnimation/BackToTheFuture the animated series]] when a young Strickland is shown as a MP back in the 1940s.

->'''Voiced in the Creator/TelltaleGames series by:''' Rebecca Sweitzer (present time) and Shannon Nicholson (younger version)
Sister of Gerald Strickland. A CrazyCatLady Marty meets in 1986. Because Marty interacts with her and young Emmett in 1931 they both fall in love, this little mistake throws the timeline into jeopardy and prevents the events of the movie from ever happening.
----
* AdaptationalVillainy: She is much more ruthless in the comic book adaption of the game. Not only she considers her action an act of God, [[spoiler:she also has no qualm in killing people]]. On the flipside, in the end [[spoiler: she feels remorse and willingly turns herself in to the police in the comic, whereas she has to be dragged kicking and screaming in the game]].
* AllGirlsWantBadBoys: [[spoiler: In the game finale, with Kid Tannen, of all people.]]
* BigBad: The main antagonist of the game.
* {{Catchphrase}}:
** "It's a fact, look it up."
** "Hooligans!"
** She borrows the “slacker” catchphrase her brother uses at least once or twice.
* ClingyJealousGirl: By 1986C she won't let Doc so much as interact with another woman.
* {{Cloudcuckoolander}}: By the time Episode 5 rolls around, Marty exclaims, "Jeez, that lady was always a loon!"
* CrazyCatLady: The original 1986!Edna and [[spoiler: Crazy, Old 1931!Edna]].
* DisproportionateRetribution: Just because she has a fear of dogs, Edna calls dogs a pest and has all dogs in Hill Valley impounded in 1986C.
* DryCrusader: [[spoiler:She sets ''Hill Valley'' accidentally ablaze while trying to burn down a saloon.]]
* EpicFail: [[spoiler: While in 1876, Edna tried to burn down Hill Valley's saloon since her grandfather wouldn't do anything about it. This ended up ''burning down all of Hill Valley.'']]
* EvilOldFolks: Exaggerated in Ep. 3 when she becomes a dictator.
* {{Foil}}: In Episode 3, she ends up becoming one to Part II's Biff, in which both of them end up controlling all of Hill Valley due to the consequences of time travel, including owning the police, but whereas Biff turned Hill Valley into a chaotic, lawless, biker-filled wasteland, Enda turns Hill Valley into a pristine police state where mundane liberties are punishable by brainwashing.
* FromNobodyToNightmare: Whenever Edna gets a drop of power, there are always serious consequences.
* GrumpyOldMan: She's never happy in her old age. [[spoiler: At least until her defeat and reformation.]]
* HollywoodToneDeaf: However, her song [[spoiler: is actually quite effective when sung by Trixie.]]
* {{Hypocrite}}: When encountered in 1986 at the beginning of the first episode, she chides Marty not to romanticize the past. She actually does just that relative to ''her own'' past, loving 1876 for how "pure" it is before Beauregard Tannen shows up. Also, see "StrawHypocrite" below.
* InsaneTrollLogic: [[spoiler: As Mary Pickford, she claims that Doc/Citizen Brown and Marty tricked her into using the [=DeLorean=] and sending her back to 1876, leading her to destroy Hill Valley and puts full blame on them when she regains her memories]].
* KarmaHoudiniWarranty: [[spoiler:Edna manages to get away with burning down the Hill Valley speakeasy in 1931 in many timelines but by the end of the game and after altering history several times, she is finally arrested.]]
* KnightTemplar: Her views of justice are... ''petty'', to say the least.
* LethallyStupid: [[spoiler: She once burned down the entire town of Hill Valley in her protests.]]
* LoveRedeems: [[spoiler: Hooking up with Kid Tannen results in both of them mellowing out a ''lot''.]]
* LovingAShadow: After Marty talks with young Edna about the nature of her relationship with Emmett, it becomes apparent that she loves what his scientific genius can do for her causes more so than Emmett as a person.
* MoralGuardians: InUniverse. She forces her views on what's right and wrong on everybody.
* NeverMyFault: [[spoiler:In 1931A, after remembering that she burnt Hill Valley, she puts full blame on Doc and Marty]].
* NotSoHarmlessVillain: As the second half of the game reveals, she's capable of pretty nasty stuff.
* ObliviouslyEvil: She fails to see that she is no different to the "hooligans" that she hates so much. [[spoiler: When she confessed to burning down the speakeasy, she admits that she enjoyed watching the building burn but took no consideration that there may be people in there]]. Her comic book counterpart is even worse.
* PromotedToParent: [[spoiler: Becomes Biff's stepmother.]]
* PyroManiac: [[spoiler:Burning down buildings is her go-to method of fighting against vice and corruption, and her Crazy!1931 incarnation shows that she absolutely ''revels'' in it.]]
* PuppyDogEyes: Young Edna lays this trope on Young Emmett, provoking a hilarious attempt at a [[TheUnsmile smile]].
* RedHerringShirt: She initially seems to be a side character, but eventually becomes the main antagonist.
* ShadowDictator: Citizen Edna, who rules Hill Valley with an iron fist.
* SheWhoFightsMonsters: She may have had good intentions in fending off "hooligans", at least at first, but as the StrawHypocrite entry indicates, she's a violent PyroManiac who's just as evil as the "hooligans" she's fighting against. Though she starts to see the error of her ways when she discovers that she was breaking the law herself.
* SilverVixen: [[spoiler: She aged considerably better in the timeline where she married Emmett.]]
* StrawHypocrite: Yells at other people for breaking the law, but [[spoiler: broke the law herself by lighting buildings on fire.]]
* UsedToBeASweetKid: Played with. It's a plot point that multiple characters, particularly [[spoiler: Citizen Brown]], presume that she was kinder and less crazy in her youth than she becomes in her old age, to the point where even though Marty is told that Edna [[spoiler: was the arsonist]] in Ep. 2, nobody really believes it. [[spoiler: This becomes Citizen Brown's brief re-FaceHeelTurn, as he comes to believe stopping his younger self from becoming a scientist will prevent her from becoming a monster]]. However, while she is somewhat more compassionate and sane in the past - helped by the fact that her crusade is against a legitimately evil criminal - she turns out to be no less [[KnightTemplar fanatically closed-minded]], and her StartOfDarkness was well before the plot even happened. It takes [[spoiler: going to jail and ironically getting together with Kid Tannen]] for her better traits to stick around in her future.
* VillainousBSOD: [[spoiler:In the timeline where she inadvertently destroys Hill Valley and becomes [[TheHermit a hermit]] known as "Scary Mary".]]
* WellIntentionedExtremist: Heavily {{Downplayed}}. Her intentions of keeping "hooligans" is good and all, but she goes about burning their places down just to ensure they don't come back again, which basically makes her no better than those villains she's fighting against, especially since she's pretty unhinged even way before the game happened. [[spoiler:Trying to have Beauregard Tannen's saloon destroyed might be a good effort to fight crime in Hill Valley in 1876, but her crazy arsonist methods of doing so ended up having ''the entire town razed to the ground''.]]
* WhyDidItHaveToBeSnakes: [[spoiler:Terrified of dogs, at least until the ending.]]

'''Dubbed in French by:''' Creator/MarcFrancois
An acquaintance of Marty and Jennifer who leads his own gang and often goads Marty into taking reckless actions by insulting him (usually using the [[NobodyCallsMeChicken "chicken"]] trick).
----
* AdaptationalVillainy: Needles, whose deeds in the movies included the card scam in 2015 and the car race in 1985, is much more antagonistic in [[ComicBook/BackToTheFuture the comic book]], threatening to beat up Marty on multiple occasions and attempting to steal equipment from Doc's lab. In effect, he becomes Marty's own personal Tannen.
* ADayInTheLimelight: Issue #12 of the IDW comic, "How Needles Got Here", is a WholeEpisodeFlashback showing how he became the bully he is in the films.
* TheBully: Despite not being related to Biff or any of the Tannens, he fulfills the role of bullying a [=McFly=], Marty in his case.
* CasanovaWannabe: Needles tries "flirting" with Jennifer (in front of his own girlfriend, no less) in the comics. It fails, naturally.
* CelebrityParadox: According to the comics, he's a big fan of Music/RedHotChiliPeppers. Needles' actor in the movies is Michael "Flea" Balzary, who is RHCP's bassist.
* CreateYourOwnHero: When Needles tried to bully Marty into trying to steal from Doc's lab, it never occurred to him that Marty would befriend Doc by using his wits to infiltrate the lab and eventually become the hero he is in ''Back to the Future''.
* FreudianExcuse: In his backstory comic he's the product of TeenPregnancy, his parents are recently divorced, and they seemingly use expensive presents as an alternative to actually parenting him. As a result, he became the kind of kid who acts out just to get attention.
* GangOfBullies: He has three buddies who laugh when he harasses Marty and Jennifer.
* GenerationXerox: His relationship with Marty mirrors that of Biff and George. Both Biff and Needles bullied George and Marty in high school and ended up working at the same place together where they continued the bullying. While Biff was more of a physical bully and ended up as George's boss, Needles is a ManipulativeBastard who knows what [[BerserkButton buttons to push]] to goad Marty into doing what he wants and inadvertently gets Marty fired in the future.
* KarmaHoudini: He ruins Marty's life on at least two occasions and doesn't suffer any consequence. Even when Marty doesn't take his bait, Needles is shown to avoid the collision with the Rolls Royce that would have injured Marty.
* LastNameBasis: He is only referred to as "Needles"; according to the comic he insisted on it as an attempt to change his image.
* LonelyRichKid: According to the comic, his father is rich and a young Doug would frequently buy whatever tickled his fancy as soon as he could. However, his poor attitude meant that Marty was the only person who tolerated him for any length of time.
* SmallRoleBigImpact: He doesn't have a lot of screen time, but his goading Marty into a drag race was responsible for wrecking his life in one of the timelines.
* UngratefulBastard: According to the comic, Marty tried to be his friend, but this just resulted in Doug making him the butt of his jokes and pranks. The fact that Marty showed incredible patience and didn't just tell him off only inspired Needles to keep doing it, and to go even further (going from childish pranks to strong-arming him into trying to steal from Doc) as time progressed.
* WhatHappenedToTheMouse: After finishing his phone call with Marty in 2015, Needles is never seen or mentioned again in ''Part II''.

* AllThereInTheManual: [[Literature/BackToTheFuture George Gipe's novalization]] says that they're a part of a six-person cell, their leader is nicknamed "Sam", and one of their ranks is an ex-fashion model named Uranda.
* BigBadWannabe: They're murderous terrorists intent on building nuclear bombs, an agenda that could have ''far'' surpassed any of the Tannens in threat level. However their attempts to murder one single teen are completely haphazardous, with their vehicle and artilery blatantly unreliable, and after crashing they are never even heard from again. Had they not [[DirtyCoward cold bloodedly shot down a surrendering Doc]] just moments prior they could have passed as {{Ineffectual Sympathetic Villain}}s.
* BlindedByTheLight: [[spoiler:When Marty travels back in time, the flash from the time travel causes the Driver to lose control of his van and crash.]]
* ChildSoldier: Sam from the novelization. He's mentioned as being in his forties and having been a terrorist for thirty years.
* DarkActionGirl: Uranda from the novelization, described as "a twenty-five-year-old ex-fashion model from Damascus who got her kicks by pumping bullets into other people's bodies."
* EvilDuo: The ones that appear in the film: a driver and a gunner armed with an AK-style assault rifle and RPG-7. The gunner appears to be the leader as he gives commands to the driver.
* ImperialStormtrooperMarksmanshipAcademy: The shooter uses an automatic weapon while being positioned right behind Marty's car. Still he doesn't manage a single hit.
* LeaveNoWitnesses: Presumably why they target Marty because he saw them shoot Doc.
* MiddleEasternTerrorists: They're from an Arab country and intend on using a nuclear device on US soil.
* {{Revenge}}: Learning Doc gave them a bomb casing full of pinball machine parts, they come to the Twin Pines Mall to kill him.
* SmallRoleBigImpact: These guys are personally responsible for Marty going back to 1955 since Marty tries to use the [=DeLorean=] to escape; when he hits 88 mph, the flux capacitor is automatically activated, sending the car back in time. Despite this, they're not around for any of the sequels or spin-off material.
* VileVillainSaccharineShow: The franchise is for the most part lighthearted and the Tannens have humorous moments with their stupidity, but the terrorists are played completely seriously, with no comical moments whatsoever; if gunning down Doc isn't bad enough we don't know what else is.
* UncertainDoom: [[spoiler:There's conflicting information about whether or not they survived their van crashing. The novelization says that the police show up shortly after they crash and take them into custody, but there's no confirmation of this in any other media.]]

[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/emmett-brown_9686.jpg]]
[[caption-width-right:300:''"GREAT SCOTT!"'']]
->'''Played by:''' Creator/ChristopherLloyd, Creator/RogerBart (musical), Mark Oxtoby (original understudy, London musical)\\
'''Dubbed in French by:''' Creator/PierreHatet\\
'''Dubbed in Japanese by:''' Takeshi Aono (home video dub), Takanobu Hozumi (TV Asahi dub), Miyake Yuji (Fuji TV dub)\\
'''Younger Version Voiced in the Creator/TelltaleGames series by:''' Creator/JamesArnoldTaylor
Hill Valley's eccentric scientist, inventor of the [=DeLorean=] time machine and Marty's best friend. He goes along with Marty in all of their adventures through time, fixing any changes to the timeline caused by time travel.

* AbsentMindedProfessor: He forgets to shut off the machines in his lab, resulting in a coffee maker with no carafe that squirts water onto an empty hot plate, a toaster that burns the bread to charcoal, and a can opener that dumps can after can of food into Einstein's overflowing dish. When the Libyans show up, he discovers too late that he has forgotten to load the revolver he brought for self-defense. He also forgot to keep a backup stash of plutonium in the [=DeLorean=], which keeps Marty stranded in the past until the storm of '55 takes place.
* AdaptationalBadass: The video game has him ''punch out'' Beauregard Tannen in a [[OneHitKill One-Hit KO]].
* AmbiguouslyChristian: One of the days he sets an example of a historic day to visit is the birth of Christ, [[note]]Though no one really knows the date and based on how shepherds were in the field was more likely in spring than winter.[[/note]] though whether he sees it as much as a historian or believer is unknown.
* AnimalLover: In both 1955 and 1985 he has pet Dogs -- Copernicus and Einstein respectively - that seem to be as fond of him as he is of them. It says something, after all, that he tests a Time Machine (that he knows will work) on Einstein, leaves him safe in a kennel in Part II, and ''returns from 1885 to retrieve Einstein'' once Time Travel becomes possible again. Copernicus, in 1955, sees his master's name on the grave and sits there whining sadly.
* AntiHero: Doc is a force for good throughout the trilogy: he created the [=DeLorean=] time machine for altruistic reasons, and is very committed to protecting the safety and sanctity of the natural timeline. With that much having been said, Doc makes several decisions to achieve his goals that are very ethically questionable. In the first film, Doc gets the plutonium he requires for his time machine by double-crossing terrorists and puts Marty's life in danger, both intentionally (by making him stand in front of a speeding car to get a good shot of the [=DeLorean=]) and unintentionally (when the Libyans come after him for revenge). In the second film, when Doc decides that perhaps bringing Jennifer to the future wasn't a good idea after all, he has very little problem with knocking out a teenage girl and leaving her unconscious body hidden in an alleyway for quite some time. In the third film, when Marty and Doc run out of other feasible ideas they can think of to get home, they eventually decide to steal themselves a whole locomotive so they can get back to the 1980s.
* BadassLongcoat: He wears a long coat in ''Part III'' and also does some rather impressive things.
* BewareTheNiceOnes: Doc Brown is an intelligent, altruistic scientist who spends the entire series trying to do what's right, help his friends better their lives, and who wouldn't hurt a fly. However, the moment he sees Mad Dog and his friends trying to lynch Marty, he promptly shoots the rope and they takes aim right at Tannen's head. He's fully prepared to drop the hammer on him if that's what it takes to save Marty, and Tannen doesn't try to push it. Also a definite case of LetsGetDangerous.
* BigGood: He has only good intentions with time-traveling, wants to set the timeline's right so no one suffers, and is genuinely helpful to Marty in all three movies and sees him as a close friend.
* BunglingInventor: Strictly speaking, the time machines are the only inventions of his that work[[note]] That we see, that is[[/note]]. The time machine is his only invention seen in 1985, and he seems to be a lot more bungling in 1955, but in that 30-year time period, it's possible he was a lot more accomplished. He is apparently a gifted scientist otherwise, enough that he works as a freelance science troubleshooter.
* BunnyEarsLawyer: He may be eccentric but he's also on par with his scientific heroes in terms of intelligence.
* CantHoldHisLiquor: All it takes is a single shot of whiskey, and he's out like a light.

** ''"Great SCOTT!!"'' Similar to "This is heavy!" from Marty, it's a sign that things have gone pear-shaped.
** ''"IfMyCalculationsAreCorrect..."'' Too bad for Doc that they usually aren't.
* CelibateEccentricGenius: He finds the idea of LoveAtFirstSight ridiculous... until he meets Clara in the third film.
* CharacterDevelopment: Goes from believing at the start of the trilogy that "no man should know too much about his destiny" to saying that "the future hasn't been written yet. No one's has. Your future is whatever you make it!" at the end.
* CharacterTics: He often makes grandiose hand gestures while talking. Creator/ChristopherLloyd said he based his portrayal of Doc, in part, on conductor Leopold Stokowski, i.e. Doc is conducting the world.
* {{Cloudcuckoolander}}: He is famous for his quirky and eccentric personality.
* CoolOldGuy: The guy's built a TimeMachine out of a rather poor car, for starters.
* CrazyPrepared: He travels with a briefcase full of money from different time periods, just in case. "Have to be prepared for all monetary possibilities."
* DeadpanSnarker: It's rare, but he has his moments.
-->''[Marty points out his father, who has a "kick me" sign on his back]''\\
'''Doc:''' Maybe you were adopted?
* {{Deuteragonist}}: For the entire series, Doc is the second-most important character. However, he gets far more focus in ''Part III'', to the point that he's the main character of the third movie.
* DiesDifferentlyInAdaptation: In the original trilogy, Doc is shot by the terrorists he conned to get plutonium to power the time machine. For whatever reason, they're absent in the musical and the risk to Doc that accidentally sends Marty back in time is radiation poisoning.
* DiesWideOpen: Subverted towards the end of Part I. His eyes are wide open but it turns out to be a DisneyDeath.
* EinsteinHair: How ''did'' he get his hair to stick out like that? The game expands on this. During the 1931 Hill Valley Science Expo. Young Emmett is driving his flying rocket-powered car, which explodes violently. When Emmett exits the expo, his hair became like his movie counterpart, as a result of the explosion (which he didn't have before). He comments that after that incident, he got banned from the expo for at least 50 years.
** Lampshaded during Doc's cameo in the queue for ''Ride/TheSimpsonsRide''; Krusty has bought the Institute of Future Technology (after Professor Frink accidentally ran over the investor who would've kept the IFT running), and tells Doc he can tear tickets if he gets a haircut. "Fine by me! It takes me three hours every morning just to get it like this!"
* EvenNerdsHaveStandards: Doc is himself an eccentric and something of a social outcast in town, but even he is appalled at just how pathetically socially inept George [=McFly=] is.
* FanOfThePast: Doc is a fan of the Old West, and gets to live in it by the time ''Part III'' rolls around.
* ForScience: His interest in time travel is completely selfless: he speaks in the first movie of its use for historians and scientists. However, he soon recognizes the problems time travel ''will'' cause in unscrupulous hands, and has no problem ordering Marty to destroy the time machine.
* FriendlessBackground:
** At the time of the films, he has only Marty and his pet dogs, because no one in Hill Valley wants to come near "crazy old man Brown."
** Subverted in 1885, where as the town blacksmith he's well-liked by the town he's on a first-name basis with the saloonkeeper and the mayor.
* FriendlySniper: In the third film, he constructed a sniper rifle while in 1885 which he uses to shoot a rope hanging Marty.
* GadgeteerGenius: He's quite adept at adapting technology to the limitations of the time period he's in.
* GentlemanAdventurer: Has shades of this. (Though he had the foresight to try ''not'' to alter historical events.)
* GoingNative: Fits right in with 1885 California.
* HawaiianShirtedTourist: Played with. Doc is rarely seen without a tacky luau shirt, and he ''is'' a tourist. Makes sense since he's allergic to synthetic fabrics and real Hawaiian shirts are made out of cotton.
* HeroesLoveDogs: He has dogs [[ThemeNaming named after famous scientists]], Einstein in 1985 and Copernicus in 1955.
* HeroOfAnotherStory: He leaves to discover the future at the end of the first film, and after he was accidentally sent back to 1885 at the end of the second movie, he's been living as Hill Valley's local blacksmith for almost 9 months.
* HerrDoktor: Played with. Doc has no Germanic accent or notable behaviors, but he mentions that his parents were the 'von Brauns' until WWI.
* HeterosexualLifePartners: With Marty. In the first film, Doc sacrifices himself to save Marty from the Libyans, and Marty returns the favor by ensuring that he gets the news of his impending death. Throughout the entire trilogy, they're by each others' sides, protecting each other and providing the fandom with many crowning moments of heartwarming.
* HotBlooded: Even more so when he's 17. The present Doc admits that he's nowhere near the bravery his past self was.
* IconicAttributeAdoptionMoment: In the AlternateContinuity videogame ''VideoGame/BackToTheFutureTheGame'', his younger self has an experiment explode and it transforms his hair into the Eisteinian wig that we all know and love. This also marks the point that he fully dedicates his life to science instead of the life of law that his father wants for him.
* IfMyCalculationsAreCorrect: When Doc's baby hits 88 miles per hour, you're gonna see some serious shit.
* IndyPloy: More subtly than Marty, but Doc can be surprisingly pragmatic when he needs to be.
* IntergenerationalFriendship: It's a credit to the actors that we, as viewers, don't question why a skater punk and some old guy would hang out together. But just in case you insist in explanations:
** The [[AllThereInTheManual original script]] had a line by Marty explaining that Doc hired him to clean his garage. Marty, being a music aficionado, was impressed with Doc's vintage record collection. The rest is history.
** The screenwriter decided it wasn't necessary to explain how they first met. Doc is a local pariah and a weirdo, and Marty is clearly a rebel. It's inevitable that Marty would snoop around Doc's garage at some point.
** [[WordOfGod Bob Gale himself]] finally gave a rather heartwarming explanation [[http://mentalfloss.com/article/28526/back-future-co-creator-bob-gale-explains-how-marty-and-doc-became-friends over on Mental Floss.]] [[invoked]]
*** The IDW comic book expanded on this in the first issue, showing that in 1982, Needles bullied Marty into trying to steal from Doc's lab. Marty was able to get inside using his wits rather than brute force, which impressed Doc enough to offer him a part-time job as his assistant. He didn't actually need help, but Marty's enthusiasm convinced him to hire the young man on the spot.
** Another explanation could be drawn from the movie -- that their friendship is a StableTimeLoop. Marty and Doc are friends because Marty helped him in the fifties (and in the game, saved him in the thirties), so Doc knew who he was in the eighties and became friends with him, thus leading to him once again do all of those things.
** The two friends over at ''[[Podcast/BlankCheckWithGriffinAndDavid Blank Check]]'' subscribe to the theory that Marty felt the absence of a male role model and proper father figure growing up, and naturally gravitated to Doc, who is in many ways the opposite of George [=McFly=].
* LargeHam: What would you expect from Creator/ChristopherLloyd?
* LiteralMinded: This comes up a couple of times in the first movie, where he takes Marty's use of slang[[note]]"This is heavy!"[[/note]] at face value in 1955. (In context, this takes place in an era when nuclear war between superpowers was starting to look more likely. It's not the stretch it would be now to have worried that we'd be slingin' around bombs to the point of affecting ''Earth's gravity''.)
* LoveAtFirstSight: Though skeptical of it, it comes true when he meets Clara, which is reciprocated. Becomes a bit of a problem when he and Marty need to get [[TitleDrop back to the future]].
* MadScientist: He ''is'' a bit eccentric and goofy, but Doc has kindly intentions.
* MayDecemberRomance: Played with. Historically speaking, Clara was around 60 years older than him, but biologically speaking, Doc was about 30 years older than her when they first meet.
* MeaningfulName: His first name is "Time", pronounced backwards. His ambition is to travel in time.
* TheMentor: To Marty, especially in ''Part III'', when he helps him learn that there's no point in losing his temper whenever somebody calls him "chicken" (or "yellow" in 1885).
* MisunderstoodLonerWithAHeartOfGold: He has the rumors of being a "crazy old man", and Marty was even warned not to go near him, but did so anyway and befriended him, according to WordOfGod. His main purpose with time-traveling is to help mankind with their problems; he refuses to alter it for personal gain, [[WhatTheHellHero which he calls out on Marty for trying to do in the sequel]].
* MysteriousMiddleInitial: What exactly the ''L'' stands for isn't stated until the animated series, when an EvilFormerFriend of his refers to him as "Emmett Lathrop Brown."
* NiceGuy: Doc is an eccentric, mad scientist who was willing to steal plutonium from terrorists to fuel his time traveling car. However, he genuinely cares about Marty and is a relatively decent guy in general.
* OffscreenMomentOfAwesome: Doc's second time machine was built in the Old West and runs on steam, which is a massive upgrade from relying on plutonium, lightning and futuristic technology to power the original time machine.
* OlderThanTheyLook: He's nearly one hundred years old in the game, yet still looks like a man in his sixties. {{Justified|Trope}} by the fact that he took advantage of future medicine to rejuvenate himself and increase his lifespan. [[TooMuchInformation They also replaced his spleen and colon.]]
* OmnidisciplinaryScientist: Aside from inventing a time machine with an onboard nuclear reactor, he's also managed to build a working refrigerator (well, it can produce ice, anyway) using 1885 components[[note]]working refrigeration units actually existed at the time - the truly impressive thing here is that he did it with parts you could find in a podunk hamlet like Hill Valley[[/note]], and a second time machine that runs solely on steam power (again, using components available around 1885). Also, when he meets Clara and lets slip that he's a scientist, he mentions that he's a student of all sciences.
* OnlyFriend: Marty is all Doc has except for his dogs. Doc is a decent and loyal man who happens to have the reputation of being a MadScientist. Marty feels out of place himself but nonetheless knows enough about making friends to have the fellow members of his garage band.
* PapaWolf: To Marty, he draws away the Libyan terrorists' gunfire to him so Marty can get away in ''Part I'' and in ''Part III'', he saves Marty from being hanged and threatens to shoot Mad Dog Tannen in retaliation. To Jules and Verne, Doc goes through a variety of feats in ''[[WesternAnimation/BackToTheFuture Back To The Future: The Animated Series]]'' to protect them such saving Verne from falling to his death from the top of Independence Hall in the episode "Go Fly a Kite" and rescuing both boys from a gang in the episode "Dickens of a Christmas."
* TheProfessor: In the original draft, he'd been called "Professor Brown" before it was recommended that he'd be called "Dr. Brown" or "Doc". This new nickname became so iconic that during the filming of ''Film/TheFrighteners'' years after BTTF, Creator/MichaelJFox kept calling the Judge character "Doc".
* RedOniBlueOni: The blue to Marty's red.
* RichesToRags: As Marty finds out when he's in the 1950's, Doc used to be loaded, but he spent it all on his time travel experiment, reducing him to work as a repairman. Doc, however, doesn't mind as the money isn't something he cares about.
* ScienceHero: One of the rare cinematic heroes who is known for his intellect and courage, but not for being a man of action. That said, he will not hesitate to put his body on the line to protect his friends, and he gradually develops into quite a badass gunslinger in the old west.
* SdrawkcabName: His first two names. His first name Emmett is "time" pronounced backwards, and his middle name Lathrop is "porhtal", as in "time portal".
* SesquipedalianLoquaciousness: Especially in the [[WesternAnimation/BackToTheFuture animated series]]. In the DVD commentary, it's lampshaded that Doc will use a bigger word when he could easily use a smaller word, such as calling a dance "A rhythmic ceremonial ritual" even though the word "dance" was clearly written.
* SophisticatedAsHell: "IfMyCalculationsAreCorrect, when this baby hits 88 miles per hour, [[PrecisionFStrike you're gonna see some serious shit.]]"
* SymbolMotifClothing: He's wearing a shirt decorated with locomotive trains in ''Part II''. The same shirt becomes his bandanna in ''Part III''.
* SupportingProtagonist: In ''Part I''. He serves as Marty's best friend but is merely a scientist who in the past will help him get back to the future at the end. The movie is really about Marty fixing his teenage parents' relationship.
* TookALevelInBadass: His first appearance in ''Part III'' involves him rescuing Marty from being hanged by shooting the rope holding him up, then proceeds to get Buford and his goons to run off. He also figures out how to build a new time machine from scratch while living in the Old West.
* TrueCompanions: [[RidiculouslyAverageGuy Marty]] and [[ReluctantMadScientist Doc]] have a [[OddFriendship very strange]] but very strong bond. They are separated by interests and [[IntergenerationalFriendship age]], but they would [[HeroicSacrifice sacrifice themselves]] for each other without a second thought. That's during the films. It gets more flagrant after the video game.
* UncattyResemblance: Doc and his dogs all have EinsteinHair.
* TheVonTropeFamily: In ''Part III'' Doc explains that his family use to be the "Von Brauns". He goes on to explain his father changed it to Brown because of UsefulNotes/WorldWarI.
* WordOfDante:[[invoked]] Bob Gale guesses that Doc was involved with the Manhattan Project, but became an outcast and spent the remainder of his life trying to invent something beneficial for humanity. Hence the portable nuclear reactor which he sank his entire fortune into. This would also explain his cynical predictions for the future in 1955 ("Of course! Because of all the fallout from the atomic wars!") Became (semi-) canon on the IDW Publishing BTTF comics (written by Gale).

!!Emmett Lathrop "First Citizen" Brown
An alternate Emmett Brown created by Marty's errors in the game. As different from the original Doc as you can get. Considering who First Citizen Brown is, he embodies similar tropes, but to avoid redundancy, the following are either exclusive to First Citizen Brown or ones significantly changed from Doc.

* AbsentMindedProfessor: Less than the original Doc Brown. Thanks to or because of Edna's influence on him.
* AdaptationalHeroism: He is much more sympathetic in the comic book adaption of the game.
* AlasPoorVillain: [[spoiler:Asks Marty for forgiveness before fading away from existence.]]
* AntiVillain: He actually has no idea that he's evil.
* BigBrotherIsWatching: In Episode 3, "Big Brother" is Citizen Brown. [[spoiler:Though it's really Citizen Edna who pulls the strings.]]
* DecoyLeader: He thinks that he's in charge, but Edna's TheWomanBehindTheMan.
* FaceHeelTurn: See WhatTheHellHero below.
* HeroicBSOD: See his MyGodWhatHaveIDone entry below.
* InkSuitActor: The hairstyle design changes reflect Christopher Lloyd's real-life baldness.
* MakeWrongWhatOnceWentRight: But from his own perspective, it's [[SetRightWhatOnceWentWrong the opposite.]] [[spoiler:After he learns that Edna is miserable in the normal timeline, and thanks to his remaining love for her, he sabotages Marty's work convincing his past self to enter the science expo to ensure that he will be together with Edna in the future.]]
* MyGodWhatHaveIDone: Once he realized his wife Edna used him and his science to try to turn Hill Valley citizens into mindless robots.
* ReasonableAuthorityFigure: Unlike Edna, he hears out Marty's case before branding him as a troublemaker for Citizen Plus.
* RedemptionEqualsDeath: [[spoiler: Dies saving Marty from Edna's car assault.]]
* RefusalOfTheCall: Never became the scientist Doc Brown became, instead ruling Hill Valley with an iron fist. [[spoiler:But it's Citizen Edna who pulls the strings.]]
* ScienceIsBad: He blames his science for turning [[spoiler:Edna]] so corrupt in the future. He's wrong, of course, but he's unlikely to listen to reason...
* WellIntentionedExtremist: He wanted to change the world, but he went at it in the wrong way.
* WhatTheHellHero: Calls out Marty on this, because Marty fixing the timeline equals him and his life being erased from existence. He [[TakeAThirdOption takes a third option]].

!!Clara Clayton
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/teachers-claraclayton-590x350_6737.jpg]]
->'''Played by:''' Creator/MarySteenburgen\\
'''Dubbed in French by:''' Creator/FrederiqueTirmont
A schoolteacher who originally perished in 1885 in a ravine. Doc Brown rescues her during his time in 1885 and remains with her to start a family in that time.

* AdaptedOut: She doesn't appear in the musical, which ends the story after the first movie.
* AlliterativeName: '''CLA'''ra '''CLA'''yton.
* BornInTheWrongCentury: In the "Clara's Story" section of [[ComicBook/BackToTheFuture the comic book]], Clara muses about how she and Emmett are like this, with Emmett fitting in better in the past, and her own desire to leave the past and visit (or live in) the future.
* CatchphraseInsult: In the animated series, her preferred word for someone she dislikes is "buzzard".
* ConvenientlyAnOrphan: The fact that her parents are dead and she's seemingly alone in the world frees her up to leave her era and traverse the timeline with Doc.
* DamselInDistress: Doc saves her from falling in the ravine and later from falling off the train.
* DrivenToSuicide: WordOfGod [[http://bttf.wikidot.com/official-bttf-faq#toc17 suggests]] she might have deliberately jumped into the ravine after Doc was shot by Mad Dog Tannen.
* GeekyTurnOn: "You've read Creator/JulesVerne?", "I ''adore'' Creator/JulesVerne!" Doc's science background also intrigued her.
* InSpiteOfANail: She died falling into a ravine in the original timeline but Doc saved her in the second. WordOfGod says she might have jumped in on purpose after Doc died.
* LoveAtFirstSight: Becomes rather flustered when she first lays eyes on Doc after [[RescueRomance he saves her life]].
* {{Love Interest|s}}: She becomes Doc Brown's love interest after they fall in love at first sight.
* MayDecemberRomance: Clara's in her thirties while Doc is in his sixties. Played with considering she was born nearly a century before he was.
* PluckyGirl: She's crazily determined enough to climb all the way to the train's engine room, despite all the explosions.
* {{Schoolmarm}}: She is Hill Valley's new schoolteacher in 1885. She still dresses like this even in the present.
* SkepticNoLonger: Predictably, she did not buy Doc's initial claim that he was from the future and assumed his love for her was all a lie, until she overhears how truly devastated he was to have lost her heart. She ditches the train and rushes all the way back to his shop to make things right, only to find Doc's time machine model sitting on the railroad set. Realizing the truth, she makes a mad dash to catch him aboard the train.
* TookALevelInBadass: In the animated series, she joins Doc on his adventures and engages in more action.
* UncertainDoom: WordOfGod suggested she might have killed herself in the timeline where Doc was shot but says he'd leave it up to the viewers to decide if that was true
* WomanScorned: When she believes [[CassandraTruth Doc is toying with her]], she calls him out, slaps him, and slams the door in his face.
* WrenchWench: At the end of one comics story, Clara is seen adjusting the armature of the Jules Verne train with a wrench, and other stories imply that she had some hand in assisting Doc with the train's construction.

[[folder:Jules Brown]]
!!Jules Eratosthenes Brown
[[quoteright:340:https://static.tvtropes.org/pmwiki/pub/images/jules_9.jpg]]
->'''Played by:''' Todd Cameron Brown

The elder son of Doc Brown and Clara Clayton. A major character in the animated series, he takes after his father by using big words and having high intellect for a child.

* AdaptedOut: Doc never meets Clara in the musical, so he and his brother don't exist there.
* AscendedExtra: His only appearance in the original films is a brief, non-speaking appearance at the end of the third film. However, he becomes a main character in the animated series.
* BigBrotherBully: His relationship with Verne is fraught with fights, some of them caused by Jules being an InsufferableGenius. "Go Fly a Kite" saw him tell his brother that his non-geeky personality proves he's not a Brown.
* FreeRangeChildren: He (and his brother) frequently take the [=DeLorean=] and gallivant [[ExaggeratedTrope around the time stream]]. Sometimes it's {{zigzagged|Trope}} when Marty is along on a particular adventure.
* IJustWantToHaveFriends: "[[Recap/BackToTheFutureTheAnimatedSeriesS2E7TheMoneyTree The Money Tree]]" has Jules growing tired of being an outcast due to his high IQ and inventing the tree of the title to get attention.
* JerkWithAHeartOfGold: Jules' personality in the animated series. His sibling rivalry with Verne sometimes goes to cruel lengths, but he honestly does care about his little brother and is a decent person in general.
* KidFromTheFuture: He and Verne meet past versions of their parents in multiple episodes.
* NerdyBully: In the cartoon, he often picks on Verne, while also showcasing his superior intelligence.
* NamedAfterSomeoneFamous: His first name is, of course, a reference to Jules Verne.
* NotSoAboveItAll: Jules may be a ChildProdigy and act rather grown-up, he still has a number of more youthful (and goofy) qualities. In "Roman Holiday" and "[[Recap/BackToTheFutureTheAnimatedSeriesS1E12Retired Retired]]", he demonstrates a love of pranks that matches his brother's, and in "St. Louis Blues", he shows that he's fond of roller coasters (even if that's sometimes crossed over with a desire to do science on them).
* OmnidisciplinaryScientist: In one episode, he creates a machine that prints newspapers from the future. In another episode, he creates a money tree.
* PrefersProperNames: Jules always calls Marty "Martin", notably being the only person to do so, as his parents and younger brother all use the nickname. This fits with Jules' tendency towards SesquipedalianLoquaciousness.
* RunningGag: Shared with his brother, a conversational gag that originated in the cartoon and carried over into the IDW comics:
-->'''Jules:''' <says something in an [[SesquipedalianLoquaciousness overly complex or erudite way]], for example: "I am formulating a brilliant concept!">\\
'''Verne:''' <says the exact same thing, but simpler, having failed to understand, for example: "Who cares, what we need is a good idea!">
* SesquipedalianLoquaciousness: In the animated series, he's even more prone to using long words than [[TheProfessor his father.]]
* SiblingRivalry: His and Verne's fights kick off a lot of the episodes.
* SkepticNoLonger: In the comics, when he first sees his father disappear in a time machine. He took it for granted that Doc had been making the whole thing up.

[[folder:Verne Brown]]
!!Verne Newton Brown
[[quoteright:340:https://static.tvtropes.org/pmwiki/pub/images/verne.jpg]]
->'''Played by:''' Dannel Evans

The youngest son of Doc Brown and Clara Clayton, a major character in the animated series. He's much more of a troublemaker than his brother, and acts his own age.

* AdaptedOut: Doc never meets Clara in the musical, so he and his brother are non-existent.
* AscendedExtra: His only appearance in the original films is a brief, non-speaking appearance at the end of the third film. However, he becomes a main character in the animated series.
* BlackSheep: Verne does not have the same scientific interests or intelligence as his father, though he does have the blond hair Doc had as a younger man (and a bit more common sense). His brother Jules likes to tell him he was adopted. [[SubvertedTrope However]], it's mostly Verne that feels this way (encouraged by his brother); Doc and Clara love him every bit as much as Jules.
* CatchphraseInsult: The cartoon version likes insulting people (especially Jules) with "skunkhead."
* CuteButCacophonic: In the cartoon. He's a cute little tyke, but he doesn't have an indoor voice.
* EmbarrassingFirstName: In "A Verne By Any Other Name", after being bullied about his name, Verne went back in time to convince the real Jules Verne to change his name; failing at that, he travelled back to his own birth to convince his parents to name him something else.
* {{Expy}}: He wears a coonskin cap like Lorraine's younger brother Milton from the first movie.
* FreeRangeChildren: He (and his brother) frequently take the [=DeLorean=] and gallivant [[ExaggeratedTrope around the time stream]]. Sometimes it's {{zigzagged|Trope}} when Marty is along on a particular adventure.
* FunnyBackgroundEvent: Infamously in ''III'', when the actor playing him had to go to the bathroom, and pointed at his crotch to indicate so -- not realizing the camera was rolling.
* IntergenerationalFriendship: Despite the decade or so gap between their ages, Verne gets along quite well with Marty, possibly due to being the odd people out amongst the Browns, most of whom are science nerds.
* KidFromTheFuture: He and Jules meet past versions of their parents in multiple episodes.
* LittleStowaway: His first experience with time-travel in Issue 18 of the IDW comic.
* NamedAfterSomeoneFamous: His first name is, of course, a reference to Jules Verne. It becomes a plot point in one episode, in which teasing makes him perceive it as an EmbarrassingFirstName.
* RunningGag: Shared with his brother, a conversational gag that originated in the cartoon and carried over into the IDW comics:
-->'''Jules:''' <says something in an [[SesquipedalianLoquaciousness overly complex or erudite way]], for example: "Just catenate expeditiously!">\\
'''Verne:''' <says the exact same thing, but simpler, having failed to understand, for example: "How about I follow you, instead?">
* SiblingRivalry: His and Jules's fights kick off a lot of the episodes.

!!Judge Erhardt Brown
->'''Voiced in the Creator/TelltaleGames series by:''' Creator/RogerLJackson
The father of Emmett Brown and grandfather of Jules and Verne. He immigrated from Germany to America sometime before WWI possessing just two dollars. Since then, he increased his wealth and became a judge for the Hill Valley Court House.

* FantasyForbiddingFather: He wanted Emmett to go into law and forbade him from inventing. He nearly shut down Emmett's demonstration at the Hill Valley Science Expo until Marty convinced him not to. Since then, he has become much more supportive of Emmett's dreams.
* RagsToRiches: He came to America before WWI with only two dollars to his name, and by the 1930s, he is wealthy and living in a mansion.
* TheVonTropeFamily: His original surname was 'Von Braun' but changed it to 'Brown' because of UsefulNotes/WorldWarI.

'''Dubbed in French By:''' Martine Reigner (''Back to the Future''), Brigitte Berges (''Back to the Future Part II'' and ''III'')\\
'''Voiced in the Creator/TelltaleGames series by:''' Claudia Wells
Marty's girlfriend and future wife.

* AdaptationalBadass: The video game has her as a teen rebel who likes to disrupt a brutal regime oppressing Hill Valley.
* AgentMulder: At the start of the second movie, when she learns that the [=DeLorean=] is a time machine, she doesn't question it once (although she ''does'' sound pretty freaked out when she asks if they're in 2015).
* AllADream: What Doc expects/hopes she will conclude about her trip to 2015 after waking up from her faint. As expected, this is ''exactly'' what she thinks, as, even though she has no recollection of going to sleep on the porch swing, coming face-to-face with her 2015 self is the last thing she remembers before waking up, meaning that from her perspective it took place only a second ago. Marty eventually fills her in on the fact that it ''was'' all real.
* AllGirlsWantBadBoys: [[spoiler:In the alternate!1986]] in the Telltale game, [[spoiler:she's dating an ugly, stupid tool rather than Marty -- just because he plays electric guitar in a band (the Marty in the alternate timeline is apparently a grade-A nerd who plays the ukulele rather than guitar). This trope is how the real Marty wins her back, along with showing off his guitar talents]].
* ChildhoodFriendRomance: According to [[ComicBook/BackToTheFuture the comic book]], she and Marty knew each other in fourth grade, fell out of contact for a few years, then reconnected and fell in LoveAtFirstSight in 1984.
* DeadpanSnarker: In the game. [[spoiler:Well, the punk-rock delinquent version of herself, anyway.]]
* DrowningMySorrows: A deleted scene from ''Part II'' has 2015 Marty Sr. discovering 2015 Jennifer lying unconscious in their house's doorway (having [[FaintInShock fainted from the shock]] of encountering her younger self from 1985), and his reaction is a resigned sigh followed by "She's [[FutureSlang tranked]] again", implying that 2015 Jennifer (trapped in an unhappy marriage with Marty) regularly intoxicates herself with chemicals to the point that she would arrive home so drunk that she'll pass out cold as soon as she steps through the door, and Marty is used to this.
* HeavySleeper: Well, heavy ''[[FaintInShock fainter]]''. More than fourteen hours (and a major timeline shift) go by while she's lying limp on a porch swing utterly out like a light from the shock of encountering her older future self. The sudden and deafening roar of a jumbo jet flying right over her does nothing to even make her stir.
* EightiesHair: Especially with her first actress. [[spoiler:In alternate 1986, this becomes DelinquentHair.]]
* FaintInShock: As a result of the Bobs not having planned any sort of CharacterDevelopment for her and [[TheLoad not knowing what to do with her in the sequels]], this ends up being pretty much her default status in ''Parts II'' and ''III''. After encountering her older 2015 self in the middle of ''Part II'', she faints and stays out cold until the end of ''Part III'', which means that despite her unconscious body having physically visited the alternate 1985 created in ''Part II'', her consciousness never even got to exist at any point during this time to experience it before the timeline was rectified!
* FlashbackWithTheOtherDarrin: It's even the page image!
* GoodGirlGoneBad: In the game, [[spoiler:she's a [[TookALevelInJerkass bitchy]], [[DeadpanSnarker sarcastic]], delinquent rocker in the alternate-1986; this is implied to be [[LaResistance a form of rebellion]] against Citizen Brown's rule.]]
* GuestStarPartyMember: Her most significant role was in the second film. Which involved her running around her future home in a controlled panic. The Bobs have noted that if they'd intended on making a sequel, they would not have had Jennifer go to the future with Marty and Doc as they had no idea what to do with her.
* HiddenDepths: The "Continuum Conundrum" arc in [[ComicBook/BackToTheFuture the comic]] shows Jennifer taking a more active role in the plot than she did in the movies, and consequently displays sides of her that we didn't previously see.
** For instance, she shows some remarkable sci-fi savvy, mentioning how she wishes that Doc had a "time phone" or similar, and she even theorizes that the version of [[spoiler:Doc]] that they've encountered might somehow be from the original (Twin Pines) timeline, or even an AlternateUniverse. She says this comes from reading George's sci-fi novels.
** The comics show that she's also quite organized and clever in her thinking, such as when she gains the trust of Goldie Wilson, Jr. in order to get the location of Doc's secret lab. She also chastises Marty for relying too heavily on {{Indy Ploy}}s rather than coming up with an organized game plan, and is able to get him to focus on the task at hand.
* HighSchoolSweethearts: Is this with Marty, and we see that they're married with kids in 2015. But the original timeline isn't very happy, though maybe not to the extent of George and Lorraine in ''their'' original timeline - they appear to actually be HappilyMarried. Lorraine even says that she thinks that she married her son out of pity (and this is to her own ''granddaughter'')! [[spoiler:Fortunately, it's heavily implied that her and Marty's future becomes much better/happier after Marty prevents the incident that ruined his life from happening thanks to his CharacterDevelopment.]]
* InSeriesNickname: Is called "Jen" a couple of times by Marty in ''Part III'' and in the game.
** In the [[ComicBook/BackToTheFuture comic]], Needles attempts to flirt with her and calls her "Jenny". She isn't impressed.
* TheLoad: Bob Zemeckis and Bob Gale never had any sort of CharacterDevelopment in mind for her, stating that had they planned to make a sequel to the original film, they would not have put her in the car at the end. Sure enough, less than five minutes into ''Part II'', she's rendered unconscious and pretty much spends the rest of the series that way. Her actress isn't even given top billing in the film credits, even though those who play even smaller roles are.
* LockedOutOfTheLoop: It's quite clear that she has absolutely ''no'' idea what's going on when she climbs into the [=DeLorean=] with Marty. Catches up fast, though.
* LoveAtFirstSight: With Marty, according to him when explaining that the trope is possible to Doc.
* TheOtherDarrin: When Elizabeth Shue took over the role from Claudia Wells, she is introduced after the new timeline has taken hold (Marty has the truck, George is a successful writer, etc.). Marty makes no sign of the change (natch), but it makes sense in-universe that she might have different circumstances as well, but the changes were ret-conned into Marty's memory as well.
* SatelliteLoveInterest: She appeared very little in the first movie and apparently existed only so that Marty would have someone to spill exposition on in the opening scenes. Robert Zemeckis and Bob Gale tried to write her out of the sequels, but the way they ended the first movie made that difficult; she did get some development in the second and third movies.
* SecretKeeper: She becomes this once Marty tells her about (and shows her what's left of) Doc's time machine.
* UncertainDoom: When last she appeared in Part II, Marty left her sleeping on the front porch in "Hell Valley", where armed criminals and other dangers were allowed to run rampant. She wakes up alive and unharmed in Part III, but there's no telling what may have happened to her offscreen.

!!Alternate Jennifer Parker
->'''Voiced in the Creator/TelltaleGames series by:''' Claudia Wells
An alternate version of Jennifer Parker who lives in a Hill Valley turned into a dystopia-disguised-as-an-utopia by First Citizen Emmett Brown and his wife Edna Strickland. This version is no longer the GirlNextDoor type like her main timeline version but a teen rebel who dresses like a punk rocker, dyes her hair, and spray paints buildings to stick it to the Brown Administration.
----
* AllGirlsWantBadBoys: She breaks up with Marty because he was a goody-two-shoes and hooks back up with him when he proves himself a rebel.
* RebelliousSpirit: From her looks, her interests, to even her love interests are all in the name of sticking it to the Brown Administration.
* TookALevelInJerkass: Became a rebellious punk goth that had broken up with Marty when he became a "square" and rebelled against the Browns and their Citizen Plus program, constantly vandalizing buildings. This could also be a case of becoming a BrokenBird because of the terrifying dystopia she's grown up in, and perhaps that her own father supports the regime as a law officer. Of course, she is pretty nasty to Marty before hooking back up with him, and she also quickly ditches her other boyfriend in the process.
* {{Xenafication}}: The video game has Jennifer as a more awesome character than she was in the films by making her a street punk disrupting the Citizen Brown regime.

[[caption-width-right:350:''"What are you looking at, butthead?!"''[[note]]Clockwise from top left: 1955, Twin Pine 1985, 1985-A, Lone Pine 1985[[/note]]]]
->'''Played by:''' Creator/ThomasFWilson, Aidan Cutler (original, London musical), Harry Jobson (new casting, London musical), Tyler Davis (understudy, London musical)\\
'''Dubbed in French by:''' Creator/RichardDarbois\\
'''Dubbed in Japanese by:''' Genda Akira (TV Asahi dub)\\
'''Voiced in the Creator/TelltaleGames series by:''' Kid Beyond (original release), Creator/ThomasFWilson (2015 rerelease)
George [=McFly's=] boss in the original 1985 who constantly picked on George in high school in 1955. Thanks to Marty's intervention in his high school years, he becomes a humble auto servicer who would later use the [=Delorean=] to alter the timeline to his favour until Marty and Doc revert that timeline.

* ZeroPercentApprovalRating: Absolutely no one at school likes Biff due to his bullying and generally awful personality. Upon everyone finding out that he knocked Biff out cold, George instantly becomes popular among his classmates.
* AbusiveParents: He has become Lorraine's children's stepdad in 1985-A. A line from Lorraine implies he lets his goons hit her kids, he punches Marty in the stomach when he tries to stand up for his mother, and he threatens with cutting Lorraine's kids off when she threatens to leave him.
* ActuallyPrettyFunny: In the second movie, when his 2015 self goes to 1955 and overhears his younger self arguing with a mechanic over the cost of his car's repairs from the manure truck accident, he chuckles, remembering the incident with nostalgia rather than bitterness.
* AllGirlsWantBadBoys: Invoked. Biff insists on this while flirting with Lorraine on some occasions. Thankfully, she's not one of them.
* AMFMCharacterization: In 1955, he listens to Music/PerryComo on his way to the dance.
* ArchEnemy: To the [=McFly=] Family in general, but mostly Marty in the first and second movies.
* AttemptedRape: In Part I, he tries to have his way with Lorraine. Luckily, George showed up before Biff did anything to her.
* AxCrazy: When Biff goes on a tear, he takes abject glee in hurting people, be it running someone down with his car, AttemptedRape, or trying to break George's arm.
* BadBoss: He's George's supervisor in the original timeline, and practically the same bully he was to him in high school.
* BarbaricBully: Big (lampshaded), dumb (says certain things grammatically incorrect, although he's smarter than his grandson), and ObviouslyEvil (attempts to rape Lorraine in their high school years, as well as his old self going back in time to turn the present-85 into a hellhole), three out of three.
* BeingGoodSucks: Biff's redemption didn't last, as dealing with a psychotic grandson left him bitter and pining for a better life he felt entitled to.
* BerserkButton:
** He really hates manure. When Marty told him in 1985-A he heard about the manure incident in 1955 he seemed more angry about being reminded of it than confused of how Marty found out.
** He also doesn't like being compared to George [=McFly=]. As shown in 1985-A, when he [[DomesticAbuse slapped]] Lorraine for saying he's not even "half the man" George was.
* BigBad: In ''Part II''. His alteration of the timeline turns Hill Valley into a dystopia -- with him at the top -- that should be [[SetRightWhatOnceWentWrong set right]]. He's also [[TheHeavy a major antagonist]] in ''Part I'', but in this film, his bullying and jerkassery is only half the challenge Marty is faced with.
* BigStupidDoodooHead: His favorite insult is the supremely juvenile "butthead" well into his old age.
* BitchInSheepsClothing:
** The new "nicer" Biff that appears at the end of the first ''Back to the Future'' is pretty much an act given that he returns to being a massive {{Jerkass}} when he's an old man (in context, he seems ''really'' bitter about how Marty Sr. turned out). It's unknown if he's still this way in ''Part III'' after the timeline's fixed.
** The Biff of 1985-A cultivates a philanthropist image in his rise to power.
* BookDumb: He's not good at school, but as shown in ''Part II'', he's very good with cars, and in Part I, he has a reasonably successful auto-repair business.
* TheBully: Pretty much the go-to example in film. Biff is this to George, Marty, and Lorraine. In fact, he likes to push around ''everyone''. As the sequels and expanded media demonstrate, it runs in the family.
* BullyBrutality: Engages in this when he tries to run Marty into the back of a manure truck. He also tries to grope and rape Lorraine, and when George intervenes, Biff tries to break George's arm.
* BullyTurnedBuddy: PlayedWith, as it's only in the "good" version of 1985 that he became friends with George, after George stood up to him. Reformed 1985 Biff seems to be on (somewhat) friendly terms with Marty: in the beginning of Part II he's eager to show Marty his new custom-made matchbooks, but knowing the old Biff all too well, Marty seems to take this with cautious acceptance.
** Even in the original 1985 Timeline, it seems that Biff and George are probably the closest thing to best friends that they have along with workmates. Unfortunately they are just continually playing out their toxic dynamic of bully and victim from High School as middle aged men. George KNOWS Biff is an asshole and his life would be much better off without him but doesn't have the guts to stand up to him.
** [[spoiler:This is further played with in the video game, implying that while his bullying nature is actually genetic in some ways, it's also partly due to his circumstances. After Marty and Doc's adventures in 1931, Biff is no longer an unwanted child raised by his grandmother. His estranged, criminal father Irving "Kid" Tannen cleans up his act after falling in love with Edna Strickland in jail and manages to become a grounding and positive influence in Biff's life along with his new wife. The resulting version of Biff is a lot more cheerful and is on much better terms with George and his family than his previous iterations.]]
* TheCaligula: In 1985-A, his building is labeled with a gigantic likeness of him with giant neon letters that say "BIFF'S." He also spends most of his time yelling at people, and literally getting away with murder by buying out the corrupt police force. And the only reason he's as powerful as he is was because his future self literally handed him an almanac that allowed him to win at gambling at any sporting event he wants.
* CannotTellAJoke: Biff is constantly, err, [[{{Pun}} biffing]] his attempts at wordplay with lines like "Why don't you make like a tree and get out of here"[[note]]It's "leave", you idiot! "Make like a tree, and ''leave''". You sound like a damn fool when you say it wrong![[/note]] and "That's as funny as a screen door on a battleship!"[[note]]"Screen door on a ''submarine'', you dork..."[[/note]] Presumably everyone is too afraid of him to correct him. He is [[LampshadeHanging berated]] for this by his [[IHatePastMe older self]] in the second movie.
* CantGetAwayWithNuthin: In the altered 1985, where he's rather submissive to George, he can't get away with putting on only one coat of wax on any cars.
* {{Catchphrase}}:
** "Hello! Hello! Anybody home?! Hey, think, [=McFly=], think!"
** "What are you looking at, [[CatchphraseInsult Butthead]]!"
** "Hey [=McFly=]!"
** "Why don't you make like a tree [[{{Malaproper}} and get out of here]]?"
* CessationOfExistence: Old Biff fades into nothingness the moment he travels back to 2015, due to altering his own past in such a way that he wouldn't live as long. This should have caused a temporal paradox, but the consequences of his actions are thwarted before any possible cosmic anomalies could occur.
* CharacterCheck: Biff seemed to have genuinely reformed in the improved timeline, but when he sees Marty and Jennifer get into a flying Delorean, something in him clicks and he shows up in the future having undone all of his character development.
* ChildHater: As a teenager he stole a ball from some children and threw it onto a roof. Marty is a downplayed example, as despite being old enough to drive he's still 17 and thus a minor.
* CorruptCorporateExecutive: In 1985-A, as the founder of Biffco. He apparently has a head for business, as he's basically a small business owner in the 'fixed' 1985 timeline and is George's supervisor at some sort of office business in the 'starting' 1985 timeline, meaning he's this trope in both of the 'bad' 1985 timelines seen in the films (though he's a mere grown up bully in the 'starting' timeline instead of a crime boss).
* DeadpanSnarker: Very rarely, if ever. Especially [[OlderAndWiser Old Biff]] who does not really [[IHatePastMe like his past self]].
-->''[After 1955 Biff verbally and physically harasses Lorraine and yells how he'll marry her one day]''\\
'''Old Biff:''' You always did have a way with women.
* DemotedToExtra: After being the central antagonist of the first two films, he only appears briefly near the end of the third film in a fairly inconsequential role. [[JustifiedTrope Justified]] in that the majority of the film took place decades before he was even born.
* DidntThinkThisThrough: He steals the [=DeLorean=] in the ride version to travel through time and profit. Even though he knows cars, he doesn't know how to ''fly'' them. Cue Biff nearly getting killed in the prehistoric era.
* DirtyCoward: Biff's bullying is largely borne from thinking he has the upper hand on those he picks on. Standing up to him or proving you're able to fight back tends to make him back off. After George knocks him out, Biff is implied to have left him alone afterwards.
* DisproportionateRetribution: Biff really takes retaliation too far.
** His response to Marty standing up to him in 1955 was to run him down with his car.
** George punched him out in high school for threatening Lorraine. In the bad timeline 1985-A, Biff used his connections with the police to kill George personally, cover up the crime, marry Lorraine, and make her life hell.
* DomesticAbuse: In the alternate timeline in Part II, he is horrifically abusive towards Lorraine. He's physically aggressive with her, he harms her children in front of her, and it's implied he made her do things like make her get breast implants. He also uses threats to keep her under his control like threatening her children if she ever tries to walk out on him.
* EasilyForgiven: Biff forces himself in Lorraine and attacks George. Yet in the altered 1985, both of them allow him into their lives as a sort of family friend.
* EntitledToHaveYou: In 1955 he believes wholeheartedly that Lorraine is "his girl", regardless of how she feels about him. This culminates in his attempt to rape her at the Enchantment Under the Sea dance. In the altered version, he ''murders'' George and threatens to ruin her children to keep Lorraine under his thumb.
* EvilIsPetty:
** Exhibit A -- Stealing a ball from some neighborhood kids and [[ThrewMyBikeOnTheRoof hurling it onto a nearby roof]]. And then he strolls away cackling to himself.
** It's obvious that he doesn't like Lorraine for her personality; at best he'll cop a feel to her dismay. Yet in 1985-A he forced her to marry him and get plastic surgery, and threatens her kids to make her comply.
** In the alternate present, we see a headline describing George's murder; Biff, the actual gunman, crows that the police would never arrest him. The article explains that George was headed for a meeting to protest the environmental policies of Biffco.
* EvilLaugh: ''Icing on the cake.''
* FatalFlaw: His wrath and need to bully others gets him because it inevitably makes people hate him.
** His abuse of Lorraine is what causes George to finally snap and knock him out.
** [[spoiler: Per WordOfGod, Biff's abuse of Lorraine finally causes her to finally kill him in revenge]].
* FauxAffablyEvil: He acts like a guy [[VitriolicBestBuds good-naturedly ribbing his buddy]] when bullying George, but is in fact a sadistic asshole who has no problem forcing himself on women.
* {{Flanderization}}: The ''Biff to the Future'' comic drastically ramps up his {{Malaproper}} traits, to the point where he mangles at least one phrase or adage on every single page.
* FreudianExcuse: His [[TheUnseen grandmother]] sounds like a case. In the Telltale game, his father is revealed to be a notorious bootlegger.
* FromNobodyToNightmare: Once he gets his hands on the Grey's Sports Almanac from the future in the second film, Biff goes from a bully to a murderer, a {{Domestic Abuse}}r (toward's Marty's mother, no less), and CorruptCorporateExecutive. Thanks to him, Hill Valley is overrun with crime. His influence extends far beyond the town, as he is implied to be responsible for the legalization of gambling as well as allowing Nixon to stay in office for ''four'' terms.
* FutureLoser: The altered timeline had him waxing cars, most often for the [=McFly=] family, in contrast to his supervisor job in the original timeline. Seems to be aware that he's this by 2015.
* GrumpyOldMan: His 2015 self, which proved he never stopped being a jackass.
* TheHeavy: In Part I, half the conflict is getting Marty back to 1985. The other half is the 1955 Biff bullying Marty's father George, which is a more personal conflict that threatens Marty's existence since George might not get the guts to court Lorraine, marry her and sire Marty and his siblings, causing them to be [[{{Retgone}} erased from existence]].
* HeelFaceTurn: PlayedWith. Biff does become nicer in the altered timeline, but it is questionable whether he has genuinely turned over a new leaf or is simply behaving in a sycophantic manner to a wealthier and more confident George. His 2015-self bullies (who he believes to be) Marty's son with his cane, but he also doesn't like his bullying grandson Griff, is more chill about the manure incident than annoyed, and is ashamed with how stupid his younger self was, proving he's gained ''some'' wisdom, if not morals.
* HeKnowsTooMuch: [[spoiler:The elderly Biff left some other instructions for his 1985-A self: If anyone (specifically Marty or Doc) comes to him asking about the almanac, kill them.]]
* HeldBackInSchool: Despite being a year older than George and Lorraine, Biff was in the same classes as them. The 1985-A explains this by saying that he took a year helping the high school football team.
* HiddenDepths: Old Biff is a grouch, but he remembers the manure incident with amusement rather than shame. This implies he did mature a little bit.
** His teenage self was also smart enough to switch the dust jacket on his Almanac with a girly magazine to keep it from being stolen, which is a far cry from the dumb muscle he appeared to be back then.
* HighSchoolRejects: In the altered timeline, his life after high school went nowhere and he is stuck in a humiliating position, washing the [=McFly=] family's cars.
* IHatePastMe: The elderly Biff is quite embarrassed about how dimwitted the younger Biff is.
-->'''Old Biff:''' It's '''LEAVE''', you idiot! "Make like a tree and ''leave''". You sound like a damned FOOL when you say it wrong!
* IHaveYourWife: The gist of his blackmail on Lorraine in 1985-A. If she tries to leave, he'll cancel Linda's credit cards and stop covering her debts, have Dave's probation revoked, and get Marty (plus Linda and Dave, if he feels like it) jailed.
* {{Jerkass}}: He's has a callous personality up until George stands up for himself, anyway. And he seems more bitter than jerkass in 2015 - given the opportunity to go back in time, he opts to make himself rich rather than do anything to the [=McFly=] family. [[spoiler:While he does make himself rich, he turns the town into a hellhole and evidently gets himself killed years before 2015.]]
* JerkassHasAPoint: In ''Part II'', the scene where he punches Marty in the stomach after he tried to stand up for his mother is obviously meant to be a KickTheDog moment, but he does call out Marty's FatalFlaw.
-->'''Biff:''' Always a little hot-headed, huh?
** Also He says to George "Don't be so gullible. [=McFly=]". While said in a mocking tone, it is good advice after all, but he sadly [[HypocriticalHumor doesn't follow it himself since he falls for Marty's]] "[[LookBehindYou Woah, woah, Biff. What's that?]]" trick.
* JerkassToOne: He's especially nasty to George, with his bullying dating back to 1955.
* JerkJock: 1955 Biff is a textbook example.
* KarmaHoudiniWarranty: In the original timeline, he got away with bullying George well into adulthood.
** In the first movie, George gives Biff the punch he so richly ''deserves''. In the revised 1985, he is reduced to a pathetic mechanic who cowers before George.
** [[spoiler: In 1985-A, he would get away with murder and years of domestic violence toward Lorraine. However, Lorraine would eventually snap and kill him in the 1990s]].
* KarmicDeath: [[spoiler: Thanks to a deleted scene, he gets two for the price of one. In Part II, Old Biff gives the almanac to his 1955 self to create a future where he's top dog, but upon his return, he doesn't live to enjoy the fruits of his efforts; in the newly-created timeline, Biff dies at Lorraine's hands in the 1990s after abusing her for years, which means 2015 Biff disappears into thin air.]]
* KnightOfCerebus: Single-handedly responsible for bringing about the BadFuture of 1985-A in ''Part II''.
* LargeAndInCharge: Biff is 6'3" and the leader of his GangOfBullies.
* LargeHam: For a bully and a general pain in the rear, he's rather (melo)dramatic in talk and/or action. Even his 1985-A self is just as over-the-top as the original.
* {{Malaproper}}:
** In ''Part II:''
--->'''Young Biff:''' ''[to old Biff]'' Now why don't you make like a tree and get outta here?!\\
'''Old Biff:''' (''[[[DopeSlap slaps young Biff]]]'') It's "LEAVE", you idiot! "Make like a tree and ''leave''". [[IHatePastMe You sound like a damned FOOL when you say it wrong!]]

--->'''Biff:''' That's about as funny as a screen door on a battleship.\\
'''Marty:''' ''[hiding in Biff's car]'' Screen door on a ''submarine'', you '''dork'''...

--->'''Buford:''' I'll hunt you and shoot you down like a duck!\\
(''{{Beat}}'')\\
'''Buford's Henchman:''' It's "dog", Buford, "shoot him down like a dog".
* ManChild: As an adult in the original timeline, he acts ''exactly'' like his teenage bully self from 1955, having no reason to ever mature; he forces George to do his work and takes advantage of him. In ''Part II'', [[spoiler:this crosses over to PsychopathicManchild in 1985-A when he's still just as bratty and immature, but now has the wealth and power to get everything he wants. The original Biff never actually killed anyone (though he did try to run Marty down with his car, ''twice''); 1985-A Biff has no misgivings and demonstrates it.]]
* MilesGloriosus: For a sadist whom everyone was afraid of, he had a ''really'' bad glass jaw.
* MoneyIsNotPower: [[spoiler: According to WordOfGod, Lorraine would've finally snapped and killed him in the 1990s, showing that wealth would not have made him invincible]].
* MoralPragmatist: The "reformed" Biff might have given up being a bully because he can't threaten people anymore rather than any shame or maturity. The Old Biff seems more exasperated with his younger self than ashamed of his cruelty.
* MurderTheHypotenuse: [[spoiler:In 1985-A, he kills George [=McFly=] in 1973.]]
* NeverMyFault: He totals the [=McFly=] car while illegally drinking behind the wheel, and blames George for it because the latter never told him it had a blind spot.[[note]]It's common knowledge that ''all'' cars have blind spots[[/note]] In Part 1, he blames ''Marty'' for wrecking his car and getting it covered in manure, and in Part 2 he insists the mechanic pay for the damages.
* NiceJobFixingItVillain: In the first movie, Marty's [[FakeDangerGambit plan to pretend to be sexually assaulting Lorraine so George can save her]], doesn't go well because Lorraine actually ''wanted'' to jump Marty, and Marty got disgusted by it. It's only when Biff shows up and actually tries to rape Lorraine that George gets a real chance at saving the day and finally [[TheDogBitesBack standing up to him]].
* NotAMorningPerson: Biff is implied to be this. Whenever George offers to go to Biff's home with the reports for Biff to copy and pass them as his own, Biff tells George not to show up too soon for this very reason.
* OhCrap:
** He and his gang have a collective "shit!" when they realize his car is headed straight towards the manure truck.
** He has this expression on his for a split second when he sees George's expression before being knocked out in one punch.
* OlderAndWiser: 2015 Biff. He formulates a surprisingly effective plan to make his past self rich, ''after'' listening to Doc talking about the risks of meeting an alternate self, and even figures out how to make the time machine work. [[spoiler:The plan, however, firmly wipes out his OlderAndWiser trait by having his 1985-A self retain a childish temper and ultimately die well before 2015, thereby erasing old Biff from existence until Marty sets things right.]] He's also become more amused than annoyed over the "manure" incident and is clearly ashamed of how much of a blockhead his 1955 self is.
* OurFounder: Has a wax statue of himself standing in 1985-A's museum.
* OutdatedOutfit: In 1985-A, he and his gang seem to fit in more with the TheSeventies than TheEighties.
* PetTheDog: Biff seems genuinely happy that George got a novel published. Judging by the way he excitedly runs in with the first editions, it's clear that he had been eagerly anticipating the books for awhile along with the family.
** Though he does so in his usual surly way, he's quick to confront what he believes to be a stranger (actually Marty in a cowboy outfit) messing with Marty's truck.
* PinkIsErotic: In 1985-A, Biff seduces women in a pink, purple, and red home, owns pink towels, and other pink decorations. Marty confronts him while he's in a jacuzzi with 2 other women.
* PragmaticVillainy: 1985-A Biff does share his wealth with Lorraine-A and her children when he marries her...purely so he can use the threat of cutting them off to keep Lorraine in line.
* RaisedByGrandparents: Teenage Biff lives with his grandma with no sign of parents, and she doesn't seem to be a particularly nice person, either.
* ReformedBully: In the altered timeline, Biff being under George's thumb has made him give up his meanest habits. However, him calling Marty "butthead" before he recognized him in the third film -- though admittedly in response to what appeared to be someone stealing his cleaning supplies, and while dressed in a ridiculous outfit to boot -- and the behavior of his older self in the second might cast doubt on whether he's reformed or just scared of George.
* ReformedButNotTamed: In the first film, it's implied Biff is willing to stiff George on a waxing job (until George pushes the issue), and in the third film, he gets aggressive and yells "Butthead" at Marty when he thinks he's some stranger stealing his cleaning supplies. If Biff has genuinely reformed then it shows he still hasn't fully lost his edge.
* {{Retgone}}: A deleted scene from ''Part II'' shows Old Biff fading away when he returns to 2015. [[spoiler:1985-A Lorraine apparently shot him some time in the mid-90s.]]
* RetiredMonster: It's heavily implied his altered version isn't a much better person, and that his kindness is just obsequiousness to his wealthier and more successful former punching bag. His 2015 version is a bitter grouch, albeit one who more or less keeps to himself. Even then, when Old Biff gets the opportunity to restore his younger self to power, he doesn't hesitate to take it.
* TheSociopath: He's pretty much the most monstrous character in the series; he has little to no inhibitions and he would do terrible things if he thought he could get away with them. In the first film, he harasses his classmates, tries to straight up murder 'Calvin Klein' with his car (in public no less) and later tries to rape Lorraine. In the second film, in the alternate timeline he murders George, abuses George's family for twelve years, and once again tries to murder 'Calvin Klein' with his car (and enjoys it even more this time).
* SchoolyardBullyAllGrownUp: In the original timeline, he's still at it, holding power over George. In 1985-A, he has power over Hill Valley, as well as California itself. The fixed timeline subverts this, to the point that George apparently trusts him to do a good job... eventually.
* ScrewTheRulesIHaveMoney: In 1985-A.
-->'''Biff:''' Kid, I ''own'' the police.
* SmugSnake: In 1985-A, he may have money, but that hasn't improved his intelligence and cunning one bit. Despite being armed, he very easily loses the Alamanac to Marty.
* ThinSkinnedBully: In the original timeline at the start of the first movie, Biff is a bully of Marty [=McFly's=] father from his college years, that continues to demean him in the present. When George stands up for himself and punches Biff out for trying to date rape Lorraine, he never bullies him again and ultimately becomes submissive to George in the present day.
* TimeTravelingJerkass: Once he gets his hands on Grey's Sports Almanac in 2015.
* TookALevelInJerkass: One would think the loutish bully who forced himself on Lorraine couldn't get any worse. But with money and power his other versions didn't have, 1985-A Biff goes from hoodlum to psychotic tyrant and wife-beater.
* TookALevelInKindness: It is possible that the altered Biff is a much nicer man, but it could be just an act. Regardless he sees to have given up his bullying ways.
* {{Trumplica}}: WordOfGod says the 1985-A version of Biff was inspired by UsefulNotes/DonaldTrump. That version of Biff is a billionaire celebrity with strong political connections and media presence, wears his blonde hair in a conspicuous combover, has loud taste in fashion and home decor, lives in a Vegas-style skyscraper, has a massive ego, casually objectifies women, and sustains his wealth and power through unethical business practices. The portrait in Biff's office was even based on one of Trump.
* TyrannicalTownTycoon: Becomes a tyrannical billionaire in 1985-A, making Hill Valley akin to [[Film/ItsAWonderfulLife Potterville]].
* UngratefulBastard: In the ride, after riders bump his car in the prehistoric era and send him back to the present, his response is "You saved my life...Buttheads!"
* VillainousBreakdown: After the second time, he crashes into a manure truck. He screams about how he hates manure and looks like he's about to ''cry''.
* VillainousCrush: For Lorraine. Taken to disturbing levels in the second film, and this is after the AttemptedRape which is still in play in 1955-A. Even the 2015 version has lingering "feelings" for her, as he told Marty (masquerading as his son Marty Jr.) "Say hello to your grandma for me."
* VillainWithGoodPublicity: In 1985-A, he's even got his own museum dedicated to his life story.
* VillainousLineage: Descended from an outlaw, he's pretty much more of the same. No word about how his son turned out, but his grandson Griff's at least as bad as he ever was if not more. And in the game, it's revealed that his father was a notorious bootlegger.
* VileVillainSaccharineShow: Downplayed in ''Part I'', in which his only two not PlayedForLaughs KickTheDog acts were trying to run over Marty with his car and attempting to rape Lorraine, nearly breaking George's arm when he stands up to him. Played straight in ''Part II'' in 1985-A, when he becomes a CorruptCorporateExecutive who is an {{Domestic Abuse}}r, turned Hill Valley into ''Hell'' Valley and [[spoiler:murdered George [=McFly=] in cold blood]]. Even for a science fiction adventure comedy trilogy it is, Biff in this alternate timeline had become the darkest antagonist of the series.
* WickedStepmother: He becomes a gender-flipped version of this in 1985-A. Wicked doesn't even ''begin'' to describe how cruel he is to Marty.
* WouldHitAGirl: In the first film, he pushes Lorraine to the ground, and in the alternate 1985 of ''Part II'', he abuses her along with Marty, among other things making her get breast implants.
* {{Yandere}}: He's an ''incredibly'' unpleasant version of this trope to Lorraine: In 1955, he sexually harassed Lorraine in broad daylight and nearly rapes her at the prom, and in 1985-A he murders George and threatens to ruin the rest of Lorraine's children if she leaves him.
* YouKilledMyFather: [[spoiler:He killed George, Marty's father, in 1985-A. Lorraine avenges George by shooting him in turn]].

[[caption-width-right:275: ''"Hey, Gramps, I told you two coats of wax on my car, not just one! GRAMPS! What the hell am I paying you for?!"'']]
->'''Played by:''' Creator/ThomasFWilson\\
'''Dubbed in French by:''' Creator/RichardDarbois
Grandson of Biff Tannen who leads a GangOfBullies in 2015.

* AxCrazy: He's far more unhinged than Biff was and even quicker prone to violence. To quote Emmet, "He's got a few short circuits in his bionic implants." Best exemplified by his version of the "your shoe's untied" gag: while Biff would merely lightly smack the person in the face, Griff outright ''punches'' Marty Jr.
* BatterUp: He attacks Marty with a metallic bat. He even says the TropeNamer BatterUp when he attacks.
* TheBully: Like grandfather, like grandson. He notably spends his brief amount of time pushing Marty's future son around and even bullies his grandfather.
* CessationOfExistence: Implied to have happened when old Biff went back in time. Old Biff's biography lists a series of celebrity women among his conquests, implying he never settle down with whomever Griff's grandmother was. Given their mutual hatred of each other, Old Biff likely wasn't too bothered by this casualty.
* CyberneticsEatYourSoul: Doc warns Marty that Griff's "bionic implants" make him unstable. We're never given much of an idea as to what these implants are, but sure enough, Griff is unnaturally twitchy, constantly visibly stressed, and even more aggressive than Biff.
* {{Cyborg}}: He has several illegal "bionic implants" installed in his body, giving him the ability to make himself even taller over Marty and even NoSell his "what's that!" punch by automatically blocking it. It makes him an even more violent and imposing bully than Biff was, leaving poor Marty Jr. helpless. It doesn't help him win against the GuileHero Marty Sr., though.
* EqualOpportunityEvil: Unlike his ancestors, whose GangOfBullies only comprised of white guys, his has an [[AsianRudeness asian guy]] and [[DarkChick a girl]].
* HeelFaceTurn: Played with. In the comic, he appears to have eventually traded in his criminal career for law enforcement, but it turns out he was brainwashed into it. That said, he does attempt to follow the rules -- if only because he's broken so many of them that he's already on thin ice -- [[ItMakesSenseInContext and initially only opposes Marty and Doc]] [[InspectorJavert because they were suspected criminals]]. But eventually his vices are too much to keep restrained, and he devolves back into the violent thug he was first seen as anyway.
* IdenticalGrandson: He looks exactly like Biff in his younger days.
* NeverMyFault: Despite being obviously guilty of causing mayhem, when he gets arrested he indignantly declares "I was framed."
* NoIndoorVoice: While Biff can at least tone his voice down sometimes, Griff just shouts pretty much every word he says.
* PutOnAPrisonBus: Griff and his GangOfBullies are last seen being arrested after their chase against Marty ends with them crashing their hoverboards into the courthouse. The newspaper confirms their arrest.
* RabidCop: In the further future seen in the comics. As a cop, he's under strict cybernetic control, but his AxCrazy tendencies, love of MoreDakka and frothing hatred of [=McFlys=] eventually lead to him demolishing half the city just to take down a couple of perps, and ending up in cuffs (again) himself.
* SmallRoleBigImpact: He only appears and is dealt with in the first act, but it's his actions that kick off Marty and Doc's trip to 2015, which in turn kicks off the rest of the film after Marty discovers the almanac.
* SpikesOfVillainy: Griff's shoes have massive silver spikes that make his feet resemble a rhino.
* StarterVillain: He's the main villain of the first act of ''Part II'', but is arrested at the end of that and his grandfather takes over as the true villain in the film.

[[folder:General Beauregard Tannen]]
!!General Beauregard B. Tannen
->'''Voiced in the Creator/TelltaleGames series by:''' Owen Thomas
The father of Buford and great-great grandfather of Biff. During the Civil War, he was a general for the Confederate Army. At some point after the war, he moved to Hill Valley to build a saloon. In an alternate timeline, his saloon was burned down by a time traveling Edna Strickland along with the rest of Hill Valley.

* JerkassHasAPoint: By the law of the time, Beauregard's business is completely legal and has every right to shoot [[spoiler:Edna]] for breaking and attempting to burn his property.
* JerkWithAHeartOfGold: A Tannen is a Tannen and Beauregard is just as much a jerkass like the rest of his family though he has his morals. Other than making truce with a Union General during the Civil War, his reason for opening a saloon other for money is also to provide the towns people a place they can enjoy after a day of hard work.
* MythologyGag: Beauregard previously appears in the [[WesternAnimation/BackToTheFuture animation series]].
* WhiteSheep: Downplayed. He is a murdering asshole like the rest of his family, but he at least doesn't like shooting women. Of course that doesn't matter if they're trying to destroy his livelihood.

->'''Played by:''' Creator/ThomasFWilson\\
'''Dubbed in French by:''' Creator/RichardDarbois
An outlaw who terrorized Hill Valley in 1885 and Biff's great-grandfather.
----
* BerserkButton: Calling him by his nickname "Mad Dog" has apparently been Buford's for a long time as the moment Marty says it in the Palace Saloon, [[MassOhCrap every single person in the saloon either silently runs away or makes themselves scarce]].
* BigBad: The main antagonist of the third film. He killed Doc in one timeline and preventing Doc's death at Buford's hands is the reason why Marty travels to 1885.
* ChekhovsGunman: He's first mentioned in the video playing in Biff's Museum in 1985-A.
* DisproportionateRetribution: Originally, he shoots Doc in the back over a matter of 80 dollars, involving a horse that threw a shoe (which Buford shot) and the bottle of whiskey that broke as a result. He also shot a newspaper editor who printed an unfavorable story about him in 1884, which made everyone stop keeping track of his kills.
* DoNotCallMePaul: Inverted. He absolutely ''hates'' being called by his nickname "Mad Dog Tannen".
* TheDreaded: He ''terrifies'' the people of 1885 Hill Valley. So much so that the newspapers stopped keeping track of all his kills after he'd shot an editor who printed an unfavorable story about him.
* EarlyBirdCameo: Is briefly shown in the second movie by way of a history lesson on the Tannen family.
* EvilHasABadSenseOfHumor: He thinks hanging Marty and later shooting him are funny.
* EvilWearsBlack: In keeping with old-time Western films, Buford wears an all-black suit in contrast to the heoric characters who all wear lighter shades.
* {{Expy}}: Of [[Film/TheManWhoShotLibertyValance Liberty Valance]]. This was deliberate on Wilson's part, right down to calling Marty "dude".
* HairTriggerTemper: One of the reasons he's nicknamed "Mad Dog", and a major reason why everyone is scared of him.
* HistoricalHeroUpgrade: InUniverse. In the 1985-A of the [[Film/BackToTheFuturePartII second movie]], where his great-grandson Biff Tannen made himself a billionaire, the museum in his casino portrays him as a much more heroic figure than he actually was.
* IdenticalGrandson: A bit tricky to pin down the usual features of a Tannen through that mustache, but he has 'em.
* InTheBack: How Buford kills Doc in the original timeline. In a deleted scene, Buford does the same thing to Marshal Strickland when the marshal tries to stop him as he heads into town to duel with Marty.
* {{Jerkass}}: Well, he's a Tannen. What else would you expect at this point?
* KickTheDog: Shooting a man dead in a fair duel is one thing. Shooting him dead after he's taken off his gun and wants to resolve the situation otherwise and gloating about it after? That's just low. Even his gang looks shocked.
* KnightOfCerebus: Naturally, being an ''actual'' gun-toting outlaw rather than just a school bully, he's much more dangerous than the average Tannen and rivals 1985-A Biff as a threat. He almost successfully ''hangs'' Marty after their version of the "bar chase" scene and much of the third movie is spent trying to alter several futures in which he shoots either Doc or Marty to death.
* {{Malaproper}}: "I'll hunt you and shoot you down like a duck." "It's dog, Buford."
* NamesToRunAwayFromReallyFast: "Mad Dog" Tannen...you think this is a bad guy?
* NeverMyFault: [[VillainousLineage Just like his descendant]]. Buford shot his $75 horse dead, but blamed Doc for it because the latter fitted the animal with a shoe that was thrown off. And which Buford didn't pay him for.
* PoliticallyIncorrectVillain: "He once bragged that he'd killed 12 men, not including Indians or Chinamen."
** He also doesn't seem to like Irishmen, if telling Seamus never to come to the saloon is anything to go by. This marks the beginning the [=McFly=]-Tannen feud.
* PutOnAPrisonBus: [[spoiler:He and his henchmen are all arrested]] after Marty [[spoiler:beats up Buford]] at the end.
* VileVillainSaccharineShow: While Biff is a confirmed murderer and cheat, most of the damage of his antics in ''Part II'' is just a side effect of his ignorant, narrow-minded selfishness. Buford, however, is a career criminal who revels in violence and actively enjoys killing, to the point where he revels in hanging Marty and slowly suffocating him for accidentally using his hated nickname and muses about how a bullet from his Derringer could take days to agonizingly kill Doc.
* VillainWithGoodPublicity: Retroactively in the alternate 1985. The Biff Tannen Museum paints him as an outlaw of intrigue and derring-do in the vein of Jesse James rather than the ruthless bully and murderer he'll show himself to be in the next film.
* WouldHarmASenior: Before Marty got involved, he shot Doc (who's currently in his mid-sixties) with a derringer, causing him a slow and painful death. The reason for it? Doc refused to pay him $80 after a horse he had shod threw a shoe and broke a bottle of whiskey, because Buford had never paid him for the job in the first place. In the new timeline, he attempts to kill him multiple times.
* WouldHitAGirl: After Clara kicks him for making lewd comments about her, he shoves her, knocking her down. This rouses Doc's ire considerably.

[[folder:Kid Tannen]]
!!Irving "Kid" Tannen
->'''Voiced in the Creator/TelltaleGames series by:''' Owen Thomas
Biff Tannen's father and a famous mob boss in 1931's Hill Valley. The owner of the Speakeasy that was razed the same year.
----
* AffablyEvil: Unlike Biff, Kid seems to have a more reasonable side to him, such as when he turns down Marty's request if he could deliver soup from him so to not give Edna competition. Another example has him giving some of his peanuts to Marty after the latter asks for some.[[note]]Of course, Marty asks for some so he can snatch Artie's hat (that was holding said peanuts) from him.[[/note]] He also is a man of his word, as he keeps his promise to not kill Artie after Trixie begged him not to, and even must have allowed them to get together eventually, seeing as Marty's family line still exists in the altered timeline from Episode 2 of the Game.
* BreakTheHaughty: [[spoiler:His time in prison reduced him to a kind old man married to Edna.]]
* DiscOneFinalBoss: He's kinda like the BigBad in episode 1 and 2, but his role is limited to cameos in the other episodes.
* FauxAffablyEvil: Puts on a charming social front, but cracks jokes about the people he's killed.
* {{Jerkass}}: He's a Tannen, what would you expect?
* LikeFatherLikeSon: He's pretty much Biff as a gangster.
* LoveRedeems: [[spoiler:He reforms from his evil ways in the end of Episode 5. See Edna's entry for more.]]
* {{Malaproper}}: "Make like a tree and die, rat!"
* OppositesAttract: [[spoiler:With Edna Strickland.]] He's a womanizing trouble-maker while she's a HeroicWannabe trying to bring order. [[spoiler:They end up happily married and even manage to reconnect with Kid's estranged son, Biff.]]
* ParentalAbandonment: Has Biff out of wedlock with a woman named Myra Benson. They get married strictly for appearances sake, dump Biff on his grandmother, and then part ways as soon as they can. [[spoiler:After Kid's reform, he comes back for Biff (most likely due to Edna's insistance or out of regret when he actually learns what [[HeelFaceTurn love feels like.]]) and manages to reconnect with him, forming a newer, happier Tannen family with Edna.]]

The Vice Principal of Hill Valley High School.
----
* BaldOfEvil: Granted he's not so much evil as much as he's a strict jerk, but he's completely bald in 1985, and when Marty is in 1955, he lampshades Strickland's male-pattern baldness.
-->'''Marty:''' Jesus, didn't that guy ''ever'' have hair?
* CatchphraseInsult: "Slacker!"
* DeanBitterman: Even in the 50s he was against his students' wild side.
* EmbarrassingOldPhoto: In the game, Marty finds an old photo of him as a child -- dressed like a girl -- in his sister Edna's apartment.
* FunHatingConfiscatingAdult: His name is probably an inside joke on the word 'strict'.
* FutureBadass: In the crime-ridden dystopian future of the second movie, he has become an embattled survivalist who semi-successfully defends his home against the heavily armed gangs who plague that version of Hill Valley.
* HairTodayGoneTomorrow: Averted. He's down to the last few dregs of his hair in 1955 and completely bald in 1985. Played for laughs with his great-grandfather who had extremely long hair. He's shown to have a full mane of blonde hair in 1946 in "Biff to the Future".
* INeedAFreakingDrink: In 1955 at least, he kept a bottle of liquor concealed in his office.
* {{Jerkass}}: He is hardly a pleasant fellow.
* JerkassHasAPoint: He tells [[ButtMonkey George McFly]] to [[GrewASpine shape up]].
* MeaningfulName: Strickland. He's really strict.
* ReasonableAuthorityFigure: If nothing else he is willing to intervene when he sees Biff about to beat up Marty, showing that if nothing else Mr. Strickland doesn't tolerate bullying.
* TookALevelInBadass: In 1985-A. He became a shotgun-wielding survivalist because of the collapse of civilization in Hill Valley. This is presumed to be stemmed from his military combat training during UsefulNotes/WorldWarII, as shown in an episode of [[WesternAnimation/BackToTheFuture the animated series]] when a young Strickland is shown as a MP back in the 1940s.

Sister of Gerald Strickland. A CrazyCatLady Marty meets in 1986. Because Marty interacts with her and young Emmett in 1931 they both fall in love, this little mistake throws the timeline into jeopardy and prevents the events of the movie from ever happening.
----
* AdaptationalVillainy: She is much more ruthless in the comic book adaption of the game. Not only she considers her action an act of God, [[spoiler:she also has no qualm in killing people]]. On the flipside, in the end [[spoiler: she feels remorse and willingly turns herself in to the police in the comic, whereas she has to be dragged kicking and screaming in the game]].

* BigBad: The main antagonist of the game.
* {{Catchphrase}}:
** "It's a fact, look it up."
** "Hooligans!"
** She borrows the “slacker” catchphrase her brother uses at least once or twice.
* ClingyJealousGirl: By 1986C she won't let Doc so much as interact with another woman.
* {{Cloudcuckoolander}}: By the time Episode 5 rolls around, Marty exclaims, "Jeez, that lady was always a loon!"
* CrazyCatLady: The original 1986!Edna and [[spoiler: Crazy, Old 1931!Edna]].
* DisproportionateRetribution: Just because she has a fear of dogs, Edna calls dogs a pest and has all dogs in Hill Valley impounded in 1986C.
* DryCrusader: [[spoiler:She sets ''Hill Valley'' accidentally ablaze while trying to burn down a saloon.]]
* EpicFail: [[spoiler: While in 1876, Edna tried to burn down Hill Valley's saloon since her grandfather wouldn't do anything about it. This ended up ''burning down all of Hill Valley.'']]
* EvilOldFolks: Exaggerated in Ep. 3 when she becomes a dictator.
* {{Foil}}: In Episode 3, she ends up becoming one to Part II's Biff, in which both of them end up controlling all of Hill Valley due to the consequences of time travel, including owning the police, but whereas Biff turned Hill Valley into a chaotic, lawless, biker-filled wasteland, Enda turns Hill Valley into a pristine police state where mundane liberties are punishable by brainwashing.
* FromNobodyToNightmare: Whenever Edna gets a drop of power, there are always serious consequences.
* GrumpyOldMan: She's never happy in her old age. [[spoiler: At least until her defeat and reformation.]]
* HollywoodToneDeaf: However, her song [[spoiler: is actually quite effective when sung by Trixie.]]
* {{Hypocrite}}: When encountered in 1986 at the beginning of the first episode, she chides Marty not to romanticize the past. She actually does just that relative to ''her own'' past, loving 1876 for how "pure" it is before Beauregard Tannen shows up. Also, see "StrawHypocrite" below.
* InsaneTrollLogic: [[spoiler: As Mary Pickford, she claims that Doc/Citizen Brown and Marty tricked her into using the [=DeLorean=] and sending her back to 1876, leading her to destroy Hill Valley and puts full blame on them when she regains her memories]].
* KarmaHoudiniWarranty: [[spoiler:Edna manages to get away with burning down the Hill Valley speakeasy in 1931 in many timelines but by the end of the game and after altering history several times, she is finally arrested.]]
* KnightTemplar: Her views of justice are... ''petty'', to say the least.
* LethallyStupid: [[spoiler: She once burned down the entire town of Hill Valley in her protests.]]
* LoveRedeems: [[spoiler: Hooking up with Kid Tannen results in both of them mellowing out a ''lot''.]]
* LovingAShadow: After Marty talks with young Edna about the nature of her relationship with Emmett, it becomes apparent that she loves what his scientific genius can do for her causes more so than Emmett as a person.
* MoralGuardians: InUniverse. She forces her views on what's right and wrong on everybody.
* NeverMyFault: [[spoiler:In 1931A, after remembering that she burnt Hill Valley, she puts full blame on Doc and Marty]].
* NotSoHarmlessVillain: As the second half of the game reveals, she's capable of pretty nasty stuff.
* ObliviouslyEvil: She fails to see that she is no different to the "hooligans" that she hates so much.

* PyroManiac: [[spoiler:Burning down buildings is her go-to method of fighting against vice and corruption, and her Crazy!1931 incarnation shows that she absolutely ''revels'' in it.]]
* PuppyDogEyes: Young Edna lays this trope on Young Emmett, provoking a hilarious attempt at a [[TheUnsmile smile]].
* RedHerringShirt: She initially seems to be a side character, but eventually becomes the main antagonist.
* ShadowDictator: Citizen Edna, who rules Hill Valley with an iron fist.
* SheWhoFightsMonsters: She may have had good intentions in fending off "hooligans", at least at first, but as the StrawHypocrite entry indicates, she's a violent PyroManiac who's just as evil as the "hooligans" she's fighting against. Though she starts to see the error of her ways when she discovers that she was breaking the law herself.
* SilverVixen: [[spoiler: She aged considerably better in the timeline where she married Emmett.]]
* StrawHypocrite: Yells at other people for breaking the law, but [[spoiler: broke the law herself by lighting buildings on fire.]]
* UsedToBeASweetKid: Played with. It's a plot point that multiple characters, particularly [[spoiler: Citizen Brown]], presume that she was kinder and less crazy in her youth than she becomes in her old age, to the point where even though Marty is told that Edna [[spoiler: was the arsonist]] in Ep. 2, nobody really believes it. [[spoiler: This becomes Citizen Brown's brief re-FaceHeelTurn, as he comes to believe stopping his younger self from becoming a scientist will prevent her from becoming a monster]]. However, while she is somewhat more compassionate and sane in the past - helped by the fact that her crusade is against a legitimately evil criminal - she turns out to be no less [[KnightTemplar fanatically closed-minded]], and her StartOfDarkness was well before the plot even happened. It takes [[spoiler: going to jail and ironically getting together with Kid Tannen]] for her better traits to stick around in her future.
* VillainousBSOD: [[spoiler:In the timeline where she inadvertently destroys Hill Valley and becomes [[TheHermit a hermit]] known as "Scary Mary".]]
* WellIntentionedExtremist: Heavily {{Downplayed}}. Her intentions of keeping "hooligans" is good and all, but she goes about burning their places down just to ensure they don't come back again, which basically makes her no better than those villains she's fighting against, especially since she's pretty unhinged even way before the game happened. [[spoiler:Trying to have Beauregard Tannen's saloon destroyed might be a good effort to fight crime in Hill Valley in 1876, but her crazy arsonist methods of doing so ended up having ''the entire town razed to the ground''.]]
* WhyDidItHaveToBeSnakes: [[spoiler:Terrified of dogs, at least until the ending.]]

[[folder:Needles]]
!!Douglas J. Needles
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/needles.jpg]]
->'''Played by:''' [[Music/RedHotChiliPeppers Michael "Flea" Balzary]]\\
'''Dubbed in French by:''' Creator/MarcFrancois
An acquaintance of Marty and Jennifer who leads his own gang and often goads Marty into taking reckless actions by insulting him (usually using the [[NobodyCallsMeChicken "chicken"]] trick).
----
* AdaptationalVillainy: Needles, whose deeds in the movies included the card scam in 2015 and the car race in 1985, is much more antagonistic in [[ComicBook/BackToTheFuture the comic book]], threatening to beat up Marty on multiple occasions and attempting to steal equipment from Doc's lab. In effect, he becomes Marty's own personal Tannen.
* ADayInTheLimelight: Issue #12 of the IDW comic, "How Needles Got Here", is a WholeEpisodeFlashback showing how he became the bully he is in the films.
* TheBully: Despite not being related to Biff or any of the Tannens, he fulfills the role of bullying a [=McFly=], Marty in his case.
* CasanovaWannabe: Needles tries "flirting" with Jennifer (in front of his own girlfriend, no less) in the comics. It fails, naturally.
* CelebrityParadox: According to the comics, he's a big fan of Music/RedHotChiliPeppers. Needles' actor in the movies is Michael "Flea" Balzary, who is RHCP's bassist.
* CreateYourOwnHero: When Needles tried to bully Marty into trying to steal from Doc's lab, it never occurred to him that Marty would befriend Doc by using his wits to infiltrate the lab and eventually become the hero he is in ''Back to the Future''.
* FreudianExcuse: In his backstory comic he's the product of TeenPregnancy, his parents are recently divorced, and they seemingly use expensive presents as an alternative to actually parenting him. As a result, he became the kind of kid who acts out just to get attention.
* GangOfBullies: He has three buddies who laugh when he harasses Marty and Jennifer.
* GenerationXerox: His relationship with Marty mirrors that of Biff and George. Both Biff and Needles bullied George and Marty in high school and ended up working at the same place together where they continued the bullying. While Biff was more of a physical bully and ended up as George's boss, Needles is a ManipulativeBastard who knows what [[BerserkButton buttons to push]] to goad Marty into doing what he wants and inadvertently gets Marty fired in the future.
* KarmaHoudini: He ruins Marty's life on at least two occasions and doesn't suffer any consequence. Even when Marty doesn't take his bait, Needles is shown to avoid the collision with the Rolls Royce that would have injured Marty.
* LastNameBasis: He is only referred to as "Needles"; according to the comic he insisted on it as an attempt to change his image.
* LonelyRichKid: According to the comic, his father is rich and a young Doug would frequently buy whatever tickled his fancy as soon as he could. However, his poor attitude meant that Marty was the only person who tolerated him for any length of time.
* SmallRoleBigImpact: He doesn't have a lot of screen time, but his goading Marty into a drag race was responsible for wrecking his life in one of the timelines.
* UngratefulBastard: According to the comic, Marty tried to be his friend, but this just resulted in Doug making him the butt of his jokes and pranks. The fact that Marty showed incredible patience and didn't just tell him off only inspired Needles to keep doing it, and to go even further (going from childish pranks to strong-arming him into trying to steal from Doc) as time progressed.
* WhatHappenedToTheMouse: After finishing his phone call with Marty in 2015, Needles is never seen or mentioned again in ''Part II''.

[[folder:Professor Marcus Irving]]
A temporal researcher in the 20th century.
----
* EasilyForgiven: [[spoiler:For trying to steal the flux capacitor and attempting to kill Doc and Marty twice, to say nothing of lying to Marty and menacing him with evil animatronic doubles of himself.]] In fairness, [[spoiler:that was the older version of himself.]]
* EvilCounterpart: [[spoiler:To Doc Brown, with whom he shares many attributes, such as scientific knowledge and [[SesquipedalianLoquaciousness a convoluted way of speaking]]—though his taste in time-travel vehicles is comparatively underwhelming. His bitterness against Doc stems from the fact that he was on the path to discovering time travel himself, and his arc even goes in a similar direction when he falls in love with a woman and changes his priorities as a result.]]
* HeelFaceTurn: [[spoiler:At the end of the arc in which he first appears, "Who is Marty [=McFly=]?"]]
* LoveRedeems: [[spoiler:Much of his behavior springs from loneliness, and it's implied that he's starting on the right path when he begins a relationship with a woman, Gabriella Sanchez.]]
* SesquipedalianLoquaciousness: To an even worse degree than Doc.
* TerrifiedOfGerms: [[JustifiedTrope Justified]] in that he's attempting to avert the ButterflyOfDoom.
[[/folder]]

[[folder:Libyan Terrorists]]
->'''Played by:''' Richard L. Duran (Terrorist Gunner), Jeff O'Haco (Terrorist Van Driver)
A group of [[ExactlyWhatItSaysOnTheTin terrorists from Libya]] who come to the Twin Pines Mall after being cheated by Doc in their attempts to build a nuclear bomb.
----
* AdaptedOut: They're not present in the musical. As such, the main plot kicks off when Marty ignores Doc's warning to not drive the [=DeLorean=] at 88 miles per hour, desperate to get medical help to save Doc from dying from radiation poisoning.
* AllThereInTheManual: [[Literature/BackToTheFuture George Gipe's novalization]] says that they're a part of a six-person cell, their leader is nicknamed "Sam", and one of their ranks is an ex-fashion model named Uranda.
* BigBadWannabe: They're murderous terrorists intent on building nuclear bombs, an agenda that could have ''far'' surpassed any of the Tannens in threat level. However their attempts to murder one single teen are completely haphazardous, with their vehicle and artilery blatantly unreliable, and after crashing they are never even heard from again. Had they not [[DirtyCoward cold bloodedly shot down a surrendering Doc]] just moments prior they could have passed as {{Ineffectual Sympathetic Villain}}s.
* BlindedByTheLight: [[spoiler:When Marty travels back in time, the flash from the time travel causes the Driver to lose control of his van and crash.]]
* ChildSoldier: Sam from the novelization. He's mentioned as being in his forties and having been a terrorist for thirty years.
* DarkActionGirl: Uranda from the novelization, described as "a twenty-five-year-old ex-fashion model from Damascus who got her kicks by pumping bullets into other people's bodies."
* EvilDuo: The ones that appear in the film: a driver and a gunner armed with an AK-style assault rifle and RPG-7. The gunner appears to be the leader as he gives commands to the driver.
* ImperialStormtrooperMarksmanshipAcademy: The shooter uses an automatic weapon while being positioned right behind Marty's car. Still he doesn't manage a single hit.
* LeaveNoWitnesses: Presumably why they target Marty because he saw them shoot Doc.
* MiddleEasternTerrorists: They're from an Arab country and intend on using a nuclear device on US soil.
* {{Revenge}}: Learning Doc gave them a bomb casing full of pinball machine parts, they come to the Twin Pines Mall to kill him.
* SmallRoleBigImpact: These guys are personally responsible for Marty going back to 1955 since Marty tries to use the [=DeLorean=] to escape; when he hits 88 mph, the flux capacitor is automatically activated, sending the car back in time. Despite this, they're not around for any of the sequels or spin-off material.
* VileVillainSaccharineShow: The franchise is for the most part lighthearted and the Tannens have humorous moments with their stupidity, but the terrorists are played completely seriously, with no comical moments whatsoever; if gunning down Doc isn't bad enough we don't know what else is.
* UncertainDoom: [[spoiler:There's conflicting information about whether or not they survived their van crashing. The novelization says that the police show up shortly after they crash and take them into custody, but there's no confirmation of this in any other media.]]

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/dd885d4d_1e7d_44ad_b758_6b6da89ebd06.jpeg]]
[[caption-width-right:350:]]
->'''Played by:''' Michael J. Fox\\
'''Dubbed in French by:''' Creator/LuqHamet
An American settler who immigrated from Ireland, husband to Maggie [=McFly=] and brother of Martin [=McFly=] with a strong aversion to gun violence.

* ActuallyPrettyFunny: Despite his aversion to violence, he clearly enjoyed watching Marty kick Buford's ass. And gets a chuckle out of Buford's nosedive into the manure. Being [[FightingIrish Irish]], he clearly preferred GoodOldFisticuffs to gun violence. It helps that Marty was doing it to defend himself and Doc and after trying to reason first.
* DoesNotLikeGuns: While he uses a rifle for hunting, Seamus otherwise has no regard for weapons or the idiotic macho attitudes they encourage. When Marty tosses him his gun at the end, Seamus says he plans to trade it for a new hat.
* EurekaMoment: Oddly enough, Marty exclaiming that Buford was "an ''asshole''!" was one for Seamus. He realized that "Clint" finally understood he didn't have to fight everyone who goaded him into it.
* NiceGuy: He decided to help Marty, a stranger he barely even knows, and helps him move past his need to prove himself.
* OpposeWhatYouSuffered: He lost his brother to a stupid duel and doesn't want Marty to throw his life away over an idiot like Buford.
* {{Pacifist}}: He hates fighting. Though as mentioned above, it seems more that he hates ''gun'' fighting and the pain and death that comes from it. Seamus seems perfectly satisfied, pleased even when Marty forgoes the gun in favor of just punching Buford out. He also doesn't seem to have an issue with fighting in self-defense, to protect others or when other options have been exhausted, as Marty was doing with Buford, and only hates seeing people fight solely to prove themselves as tough as such an attitude is what got his brother killed.
* PapaWolf: Despite his wife's objection, Seamus has a strange feeling that he should help Marty, not knowing that the young man is actually his descendant. He also repeatedly tries to convince Marty not to fight Buford.
* RedOniBlueOni: He was the Blue to his brother Martin's Red; Seamus is someone who dislikes fighting and prefers talking things through while Martin was a hothead whose repeated attempts to prove he wasn't a coward got him killed.
* SoProudOfYou: He's clearly delighted to see Marty finally realize that Tannen is an "asshole" and that he doesn't need to prove his courage to Tannen or anyone else.
* StealthMentor: Seamus is able to change Marty for the better, preventing him from taking reckless actions just because someone calls him a coward [[spoiler:such being goaded into a drag race by Needles]]. Part of it is that he was traumatized by his brother (ironically named Martin) being in exactly the same situation and getting himself killed because of it.
* StrongFamilyResemblance: He strongly resembles Marty, due to both being played by Fox.

[[folder:William [=McFly=]]]
!!William Sean [=McFly=]
->'''Voiced in the Creator/TelltaleGames series by:''' Michael J. Fox
Seamus and Maggie [=McFly's=] Irish-American son and Marty's great-grandfather who played a role in Hill Valley's development.

* BigDamnHeroes: [[spoiler:In 1931B, William arrives just in time to help Mary and Doc when Mary Pickford, aka a time displaced Edna Strickland, held the two at gun point.]]
* StrongFamilyResemblance: Greatly resembles his father and descendant, due to all three of them being played by the same actor.
* UncertainDoom: [[spoiler:The fate of the 1931B William is unknown as he is last seen holding off Edna and allowing Doc and Marty to escape. Then again, even if he dies, this timeline is erased at the end of the game.]]

->'''Played by:''' Creator/LeaThompson, Rosanna Hyland (original, London musical), Amber Davies (new casting, London musical)\\
'''Dubbed in French By:''' Creator/CelineMonsarrat\\
'''Dubbed in Japanese By:''' Gara Takashima (TV Asahi dub)
Mother of Marty [=McFly=] and George's wife.

* TheAlcoholic: In the original 1985, she's a bit of a drinker to cope with her not-very-happy marriage, but she's worse in 1985-A to cope with the horror of being stuck with Biff.
* AllGirlsWantBadBoys: Averted. She makes it quite clear that she has absolutely no interest in Biff. She's also repulsed when Dixon tries to dance with her.
* AllWomenAreLustful: Goes to almost StalkerWithACrush levels in the first film when she grows a lustful interest in Marty.
* AwfulWeddedLife: Her marriage to George in the original timeline is more than a bit strained, but her marriage to Biff in 1985-A is much worse.
* BeautyEqualsGoodness: Inverted. She hasn't aged well in the original 1985, due to her less-than-ideal marriage to George. In the altered 1985, Lorraine has a much healthier marriage to George, and has aged gracefully.
* BrokenBird: The Lorraine of 1985-A is a shattered woman, trapped in an abusive/loveless marriage to Biff, staying with him only so that her children can live in relative comfort.
* DamselOutOfDistress: It's revealed in the second movie that she delivered a GroinAttack to Biff when he tried to pressure her into going into the dance with him.
* TheDogBitesBack: [[spoiler: WordOfGod is that in the alternate timeline, Lorraine eventually snaps under the strain of Biff's abuse and shoots him dead in the 1990s (with the same revolver he used on George, no less). By setting the timeline right, Marty may have humiliated Biff, but he also saved his life.]]
* DomesticAbuse: In 1985-A, Biff has her husband killed and threatens her into an abusive marriage. He hits Marty on a regular basis, even when Marty isn't doing anything to antagonize him. It's implied Lorraine knows what he did to George and the only reason she doesn't leave is that Biff threatens to cut off her kids' financial support and make their lives hell. Then presumably she finds out that Biff made Marty jump off the roof of their home at gunpoint, even if it was part of Marty's plan.
* FanDisservice:
** Her interactions with Marty in the 1955 portions of the first film. She's a pretty, kindhearted young woman with a desperate crush on a boy... who happens to be her time-displaced son.
** 1985-A, where Biff made her get plastic surgery, has her wear lots of makeup, and dresses her up in expensive clothing. While other movies might play the {{Fanservice}} straight, the context behind it is what makes it unappealing, and only serves to show how horrible her life in 1985-A is.
* FormerTeenRebel: Has a very prudish attitude toward teenage sexuality as a parent, looking down on Jennifer calling Marty twice in one evening. However, Marty discovers firsthand that as a teenager, his mother smoked cigarettes, drank alcohol, and fooled around with boys in parked cars. And basically semi-stalked the boy she liked, following him home. Then again considering how it worked out for her in that timeline it does make sense ''why'' she would be so prudish.
* GagBoobs: Biff-A made Lorraine-A get some by 1985-A; she doesn't enjoy them.
* GotOverRapeInstantly: [[spoiler:George ends Biff's sexual assault against Lorraine after which point she immediately appears infatuated with George and the assault is never again mentioned or addressed.]]
* GuessWhoImMarrying: Biff in 1985-A. Much to Marty's horror. Subverted in that the marriage was obviously forced, and Biff is abusive to the [=McFlys=].
* HappilyMarried: In the altered timeline, her marriage with George is ''much'', much healthier.
* HasAType: Lorraine says outright that she prefers men who have a spine and can stand up for themselves and others. She's unhappy with George being a doormat in the original timeline, is attracted to "Calvin Klein" because of his boldness in standing up to Biff, and finally falls in love with George when he saves her from Biff and Dixon.
* HighSchoolSweethearts: With George, even in the unaltered timeline where their marriage is rocky.
* IWasQuiteALooker: Very much. She's somewhat plain and a bit drunk and prudish at the start of the first film, so Marty is shocked by Lorraine's real attractiveness when he meets her in 1955. She ages much more gracefully in the "improved" 1985 that Marty returns to in the first film.
-->'''Lorraine:''' My name's Lorraine, Lorraine Baines.\\
'''Marty:''' Yeah... but you're ho... you're so h... you're so... thin!
* LadyDrunk: In the original 1985. Even more so in 1985-A. [[spoiler:And in the Citizen Brown timeline in the game.]]
* LongingLook: Throws them at Marty hard after they met.
* MamaBear: [[spoiler:A deleted scene from the second movie shows Old Biff collapsing and disappearing shortly after coming back to 2015. It is heavily implied (and later said by the producers) that by 1996, Lorraine just had enough of Biff and his threatening her children and [[LaserGuidedKarma shot him with the revolver Biff used to kill George]].]]
* MsExposition: In Part I, she tells the story of how she and George first met, which later influences most of the plot. In Part II, her 2015 self talks about Marty's problem with being called "chicken" and how it led to a car accident in the past (which comes into play in Part III).
* MsFanservice: At least in 1955 during her rebellious days as wild girl. While she dressed conservatively most of the time, her prom dress was quite revealing.
* NeutralFemale: Averted, more or less, during the final confrontation with Biff. After pleading with Biff to leave George alone, she does make an effort to rescue him, but Biff responds by simply pushing her onto the ground. It's not particularly spectacular or feminist, but she probably did all she could without having WaifFu.
** In the ruined present, Lorraine is completely helpless against Biff, who murdered her husband, forced her to marry him, treated her like an object and held her own children ransom.
* NoCelebritiesWereHarmed: The 1985-A Lorraine was modeled after various female televangelists from TheEighties, particularly Tammy Faye Meissner (aka Bakker).
* NoDoubtTheYearsHaveChangedMe: The difference between the Lorraine of 1973-A and 1985-A is downright jarring.
* ParentalIncest: Has a crush on Marty in the first film - much to his horror. Becomes a major problem. However, she doesn't know that Marty is her future son and she seems to back off after she kisses him, describing it like her feeling like she's kissing her brother.
* PracticallyDifferentGenerations: Lorraine is 16 years older than her youngest sibling Joey (plus another unnamed Baines sibling born in 1956).
* QuickNip: Has a flask with her when she and Marty are "parking" before the HighSchoolDance. Marty is concerned as he sees her future LadyDrunk persona emerging.
* SeeminglyWholesomeFiftiesGirl: Played this trope straight to a tee in her youth. At 17, she drinks, smokes, and "parks" with boys casually. In the original, unaltered 1985, she [[BlatantLies falsely]] insists to her kids that she was a genuinely wholesome 50's girl.
* {{Tuckerization}}: The original script called her Eileen. Her name was changed at the insistence of {{Creator/Universal}} boss Sidney Sheinberg, who wanted her named after his wife, actress Lorraine Gary of ''{{Franchise/Jaws}}'' fame.

Father of Marty [=McFly=] and Lorraine's husband.
----
* ActuallyPrettyFunny: Even he can't help but laugh when Biff's gang makes fun of Marty's jacket, which they think is a life preserver.
* BadassBookworm: What he becomes after his confrontation with Biff.
* BerserkButton: In issue 3 of [[ComicBook/BackToTheFuture the comic book]], 1958!George hates it when you call what he writes "sci-fi," which he equates with "cheap junk." He writes "science fiction."
* BewareTheNiceOnes: After decking his lifelong tormentor, George becomes one that you do ''not'' want to mess with.
* BumblingDad: In the beginning of the first film, he is this to a tee. Technically, he's not necessarily stupid, but he's too lacking in confidence to put his intelligence to use, being used to being bullied by Biff and essentially being cared for by Lorraine.
* ChivalrousPervert: Earlier on in the movie, in 1955, he's spying on Lorraine through the window as she undresses (Marty: "He's a Peeping Tom!"). However, his fire is lit if you try to touch Lorraine inappropriately. It drove him to overcome his insecurities and stand up to the person who has bullied him his whole life by punching him out, saving Lorraine from AttemptedRape in the process. After he has saved her, he asks if she's okay, and helps her up to her feet. His chivalry is what makes him win her heart. When Marty returns to the "corrected" 1985, George's follow-up to Marty's incredulous observation that Lorraine is "thin" is to pinch her butt, showing he's ultimately still this trope.
* DeadAlternateCounterpart: The 1985-A George, who was murdered by Biff so [[MurderTheHypotenuse he could marry Lorraine]].
* {{Determinator}}: In the improved timeline, he kept trying for almost 30 years to get his first novel published, [[EarnYourHappyEnding until he finally succeeds]].
* {{Deuteragonist}}: For the first film. Marty has to teach George to stand up for himself and others, and the entire third act falls on George's shoulders as his choice to stand up to Biff and Dixon determines whether or not Marty lives or dies. After that Marty only has to worry about being able to go back to 1985 when the clock tower is stopped.
* EatingLunchAlone: George sits by himself at the cafeteria during lunch in 1955, writing ideas for his stories.
* ExtremeDoormat: He refuses to stand up to Biff until he TookALevelInBadass towards the end of the first film.
* FakeShemp: In the sequels, especially ''Part II'', where the audience never gets a clear view of his face, aside from the scenes in 2015, where he's upside down and the actor is wearing old age makeup.
* FlashbackWithTheOtherDarrin: It may not be particularly noticeable most of the time due to clever camera work and tech, but the shots with George in ''Part II'' that aren't stock footage are played by Jeffrey Weissman.
* ForWantOfANail: In the bad 1985 timeline, he dies because Biff has him killed for petty reasons. Biff shot him personally and used his contacts with the police to cover up the crime.
* GrewASpine: Him standing up to Biff is a critical moment that fills him with self-confidence and he no longer allows himself to be bullied afterwards. When Dixon tries to muscle in on dancing with Lorraine, George initially is unsure what to do, but when it looks like Marty is done for and is about to cease to exist...
-->'''George:''' Excuse me! ''(shoves Dixon down and takes back his girl)''
* HappilyMarried: He and Lorraine are very happy together after Marty fixes the time stream.
* KickMePrank: George is the victim of a kind cruel prank when some of Biff's friends tape a sheet of paper with the words "KICK ME" on it on his back.
* KickTheSonOfABitch: Knocks out his bully Biff in a single punch.
* LovableNerd: A nerd who is more comfortable watching or writing sci-fi than he is with social interaction and who takes notes on what to say to the girl he likes. As he introduces himself to Lorraine as her "density", she seems amused by it. This probably would've succeeded if Biff hadn't shown up.
* MostWritersAreWriters: He writes little sci-fi stories and makes it big in the good timeline.
* NerdsAreSexy: Even after the big 1955 makeover, he's still a bit of a nerd (he did, after all, write and publish what appears to be a pretty hardcore sci-fi novel). However, unlike before, he's an attractive and self-confident nerd rather than a stereotypical nerd.
** Even before, Lorraine admitted that George was plenty cute, but his spinelessness and lack of self-confidence turned her off.
* ThePeepingTom: The then-teenage George [[NaughtyBirdwatching spies on Lorraine undressing from a tree next to her window with a pair of binoculars]]. This becomes a crucial plot point as this is the point where Marty alters history. When George falls out of the tree, Marty pushes him out of the way of an oncoming car... accidentally preventing his parents' original meeting. For an idea of how it originally happened, imagine Marty's actions that night at the dinner table with George in place of Marty.
* ParentsAsPeople: In the original timeline, he is a loving father, but they seem to care for him more than he does for them.
* RageBreakingPoint: When he initially tried to protect Lorraine from Biff, he was fearful and hesitant. When Biff violently shoved her to the ground and laughed, that was enough to lay him out with one hell of a punch.
* SilverFox: Originally, George in the present day looked painfully nerdy and had greasy dark hair. In the improved present George has much lighter hair, but also dresses more stylishly and appears in better shape.
* StereotypicalNerd: In the original timeline, George is a meek and introverted office worker who wears NerdGlasses, has slicked down, side-parted hair, wears a button down and tie with a pocket-protector. When Marty goes back in time, he realizes that his dad has always been this way, on top of being an ExtremeDoormat and a BullyMagnet who is picked on by Biff and struggles to talk to his crush Lorraine. This does change though as Marty teaches George to stand up for himself.
* SurprisinglyRealisticOutcome: When he [=KO=]s Biff with that Haymaker, he recoils in pain briefly. Punching someone in the face can actually be very painful due to hitting the skull, and his incredible fury at Biff might have dampened but not entirely removed the pain.
* TookALevelInBadass: Marty basically helps him rise to this point. As soon as Lorraine is shoved to the ground by drunken Biff, the fire is lit.
* UnskilledButStrong: He has less combat skill than a street punk. That said, he can throw a haymaker strong enough to knock out the much larger Biff in one hit.
* WhatYouAreInTheDark: George is too meek to stick up for himself, but when he sees Lorraine in trouble he loses all inhibition and decks Biff with a single punch fuelled by years of pent-up rage.
* YouLeaveHimAlone: Enforced by Marty, who comes up with a plan to get George on Lorraine's good side. When it turns out to be Biff instead, George still doesn't back down.

'''Voiced in the Creator/TelltaleGames series by:''' AJ [=LoCascio=] (young), Creator/MichaelJFox (alternate versions)
The youngest teenage child of George and Lorraine [=McFly=], who aspires to become a musician. He is best friends with Doc Brown, the inventor of the [=DeLorean=] time machine, but when the latter gets gunned down, he accidentally travels to 1955, where he inadvertently changes his parents' fated meeting, forcing him to fix it. After returning to 1985, he and Doc go on more time-travelling adventures to restore the space-time continuum.
----
* ActionSurvivor: Doc seems to have this impression of him, at least after the first movie. It should tell you something that, in ''Part II'', Doc's plans for Griff and 1955 basically boil down to "tell Marty what to do and let him handle it".
* AMFMCharacterization: He's a fan of Music/HueyLewisAndTheNews, listening to them at various points in the first film. He's also a Music/MichaelJackson fan, as he sings "Billie Jean" in the third film while dancing.
* AntiHero: The Telltale game turns him into one, given all the morally ambiguous things he ends up doing in order to set the timeline straight, including (but not limited to) nearly suffocating young Doc to death.
* BadassDriver: For a 17-year-old kid, he actually does very well during the brief car chase and the clocktower run. In fact, he displays driving skills that are ''not'' taught in Driver's Ed or by his father George.
** During the chase, he avoids driving in a straight line and keeps shifting from one side of the road to the other. This causes the terrorist to keep shifting from side to side and prevents him from hitting him to the point that he almost loses his gun.
** Leading up to the clocktower run, Marty is able to pull a pretty nice 180 and come to a stop right at the start point. He's also able to bring the car more-or-less safely to a stop afterward with little damage.
** Near the end of Part III, he also does a reverse-180 as an F-U to Needles.
* BeenThereShapedHistory: Downplayed. Marty encounters the future mayor of hill Valley back when he was a busboy and lets slip his eventual success, inspiring the busboy. His cover of "Johnny B. Goode" also gets noticed by the cousin of Music/ChuckBerry who convinces the latter to take influence from it. In both instances, these figures were already destined for success, but Marty sped things up.
* BerserkButton: "[[NobodyCallsMeChicken Nobody calls me "chicken"!]]" This ends up getting him into an accident the day he returns from 1885. May also qualify as a NoodleIncident, since it didn't appear in the first movie. Though that may just be a coincidence, or alternate parenting from the "new", self-confident George, who took Marty's lessons a bit too much to heart when passing them on.
* BewareTheNiceOnes: He's very sweet and friendly, but throughout the movie he's shown to be very adept at fist-fighting, only losing when he's either outnumbered, sucker-punched, or up against [[spoiler:a cybernetically-enhanced Griff.]] Furthermore, his skill at the Wild Gunman arcade game translates perfectly to [[spoiler:the wild west, and it's likely he could've won his duel with Buford had he actually been willing to kill the man.]]
* BigBrotherInstinct: He forms one over his own father in 1955, protecting him whenever he needs help. [[spoiler: Thanks to that and CharacterDevelopment on George's part, the latter becomes a better, more assertive person.]] He also plays this role towards his mother, such as when Biff harassed her in the cafeteria.
* BookDumb: Seems to actually need the exposition Doc gives... but it seems to have been him that hooked that 1985 video recorder up to Doc's 1955 TV. Maybe Doc's been teaching him?
** The IDW comic's take on how he met Doc in the first place emphasizes his intelligence by [[spoiler:showing that he easily bypassed Doc's security system by figuring out his clues. Doc was impressed enough to hire him on the spot]].
* BuffySpeak:
** In the Telltale game:
--->'''Marty:''' ''(looking at a bathysphere)'' It's some kind of... deep-sea diving thingy.
** "Time circuits on, flux capacitor...''fluxing..."''
* BullyHunter: Granted, since he's grown up seeing Biff as his father's tormentor, it's not too big a surprise that he doesn't like bullies.
* ButtMonkey: At times. He always comes into conflicts out of his hands.
* TheCallKnowsWhereYouLive: In his case, RefusalOfTheCall means he disappears from existence or is stuck in the past, so he doesn't have much choice but to comply. Come ''Part III'', he finally has the opportunity to choose without being so railroaded by the plot, and he goes with... GuileHero.

** "NobodyCallsMeChicken".
** "This is heavy!"
** "Holy [censored]!"
** ''(every time he tries to distract his enemies)'' "Hey, [[LookBehindYou what the hell is that]]?!" or "Hey, what's that?!"
** "Here goes nothing." (In the video game)
** He also tends to mutter [[SarcasmMode "perfect..."]] when things aren't going well for him.
** [[LetMeGetThisStraight "Wait a minute..."]]
* CharacterDevelopment:
** His self-confidence seems to have improved after the events of ''Part I''.
** In the first film, when he's a newbie to time travel, he's very naive and impulsive, and for the first half of the second film he remains the same. After an unsuspecting trip to the year 2015 goes horribly wrong and Marty accidentally gets his dad shot by Biff, he finally starts to take the dangers of time travel seriously and he grows significantly more cynical about the adventures in time he and Doc have by the third and final film.
--->'''Marty:''' Why do we always have to cut these things so damn close?!
** In ''Part III'', Marty finally overcomes his FatalFlaw[=/=]BerserkButton, [[spoiler:saving himself from getting killed by Buford Tannen]] and [[spoiler:saving himself from becoming a FutureLoser by never agreeing to the street race with Needles]].
* CharacterExaggeration:
** Into TheDitz in ''[[WesternAnimation/BackToTheFuture The Animated Series]]''. In the film trilogy, Marty was a bit BookDumb and sometimes did stupid things because of his impulsiveness, but he was a quick-witted and capable assistant to Doc. In the series, he's much more of a dope and continually needs the Browns (including Jules and Verne) to help him out. Lampshaded in "The Money Tree", where Jules laments that his intelligence has always made it tough for him to make friends. Marty remarks that that's never been a problem for him, right around the time he hits himself in the face with a ball he's tossing around.
** He used his [[LookBehindYou "What's that?" trick]] once in ''Part I'' and three times in ''Part II''. In ''VideoGame/BackToTheFutureTheGame'', he uses this trick constantly on everyone when it comes to the task at hand or when he's in dire situations.
* CharacterTics: His, erm... ''unusual'' sleeping position.
* ChekhovsSkill: Skateboarding, guitar shredding, and (later) arcade shooters.
* CloningBlues: In the comics, when his inability to remember the events of the Lone Pines timeline leaves him terrified that he's stolen the life of another version of himself.
* CombatPragmatist: Kind of necessary when facing guns and men twice your size (sometimes both at once).
* CompressedVice: Again, his dislike of being called a chicken. In the second movie, his parents reflect on how this was always his FatalFlaw. Would be normal if it weren't for the fact that he isn't shown to have this trait in the first movie; he has a quick temper and some {{Determinator}} aspects, but no one calls him out on anything directly. Although the fact that he takes a sip from the liquor after Lorraine tells him he's being a square might be a subtle sign of it. It's also very possible that this is a trait that was specific to the "Lone Pine" version of Marty, that was internalized (or got amplified) via DelayedRippleEffect.
** The comics give him two in a row to fuel two subsequent arcs: see "So What Do We Do Now?" and "Cloning Blues."
* CoolBoard: Apparently to make up for the fact that he doesn't have a car, originally. Due to this, and how skateboarding wasn't quite as popular in 1985, we never see him doing any tricks on it.
* CoolLoser: Supposedly. The only person we see treating him this way in the original timeline is Strickland, though. A more complete breakdown:
** In the "Cool" column: he's clever, resourceful, reasonably athletic, and a talented musician with a caring girlfriend. He veers towards TotallyRadical at times, but he mostly fits in with the other over-the-top characters in-universe.
** [[JustifiedTrope In the "Loser" column]]:, he doesn't appear to have [[LimitedSocialCircle any friends his own age]], and he has low self-esteem and handles failure (like blowing an audition) extremely poorly, probably fearing he'll turn out eternally spineless and bullied like his dad anyway.
* CrueltyIsTheOnlyOption: In the game, [[spoiler: to save the future, Marty pretty much obliterates Emmett's life in the span of two minutes.]]
* DeadGuyJunior: "Seamus" is the name of one of his ancestors, who he meets in ''Part III''.
** As is "Martin", the late brother of Seamus.
* DeadpanSnarker: At times. But not to the highest levels of snarkiness.
* {{Determinator}}: Particularly in ''Part II'', and especially during his second time in 1955. Dude just will not quit in trying to get the Almanac back.
* DistractedByTheSexy: Gets distracted by sexy women... while his girlfriend Jennifer is right next to him. She doesn't seem too bothered, though, simply turning his face back towards her.
* DrivesLikeCrazy: He constantly crashes or at least sideswipes with whatever vehicle he's driving -- including his three future selves.
* DorkKnight: To the extent that a high schooler could be reasonably expected to be, anyway.
* FamilyOfChoice: In the animated series, the Browns seem to treat him as an adoptive member of the family, even though it's not official. He's continually dropping in on them, one episode shows him in a photo with the official family, and all the members have a friendly relationship with him. It couldn't have hurt that he and Doc have been best friends for years by the time Doc met Clara and had Jules and Verne.
* {{Fanservice}}: A split-second shot of him in purple Calvin Klein underwear (which also shows quite an impressive bulge for his age). Plus in the third movie, you get a nice shot of his butt. (WordOfGod said there was much squeeing from girls at every screening they went to at the latter.)
* FatalFlaw: Calling him Chicken is always used against him. Again, see BerserkButton.
* FishOutOfTemporalWater: Takes an ''unusually'' long time to get fully acclimated to being in 1955.
* FragileSpeedster: Necessary considering that [=McFly=] men are just not too built by nature. He combines this with CombatPragmatist to outsmart the various villains (e.g., incarnations of Biff, his relatives, and his cronies) that he encounters throughout his adventures. If he ever allows himself to be drawn into a fight due to [[HairTriggerTemper calling a chicken]], he tends to go down after a really good punch or two.
* FutureBadass: If the [[spoiler:ending to the Telltale game can be trusted]].
* FutureLoser: ''Part II'' reveals that Future Marty gave up guitaring and ended up a lowly {{salaryman}}, stuck working for his high school enemy ([[TurnOutLikeHisFather à la George]]). [[spoiler:Luckily in ''Part III'', Marty manages to avert the event that led to this timeline, with the implication that he has a better future.]]
* GuileHero: He uses his wits as much as his physical ability to solve his problems.
* TheGunslinger: Thanks to [[http://en.wikipedia.org/wiki/Wild_Gunman an arcade light gun game]], he is an accomplished QuickDraw artist. Though, he does refuse to kill Buford so as not to mess up the timeline.
* HairTriggerTemper: Lampshaded by being called a "hothead" by many throughout the trilogy. This is especially true if you call him a chicken, which will make hell break loose and cause him to try to punch you out. He seems to have grown out of this by the game, however, after his CharacterDevelopment in the third movie.
* HandBehindHead: Does this gesture whenever he is nervous. Shares this tic [[SharedFamilyQuirks with his father]].
* HardHead: It's something of a RunningGag that Marty loses consciousness this way.
* HellBentForLeather: The second time Marty goes back to 1955, he dons a leather jacket.
* TheHero: The noblest character in the entire series, so this was expected.
* HeroicBSOD: Hit hard with this in the comics during the "Who Is Marty [=McFly=]?" arc.
* HeterosexualLifePartners: With Doc. In the first film, Doc sacrifices himself to save Marty from the Libyans, and Marty returns the favor by ensuring that he gets the news of his impending death. Throughout the entire trilogy, they're by each others' sides, protecting each other and providing the fandom with many crowning moments of heartwarming.
* HiddenDepths: He's a lot smarter than he seems.
* HighSchoolHustler: {{Downplayed|Trope}}. He's not really a trickster as usually seen in this trope, but he's no less lucky and helpful. Played straighter in the early drafts for the movie, however.
* IKnowMortalKombat: Learned how to sharpshoot from playing [[http://en.wikipedia.org/wiki/Wild_Gunman an arcade game]].
* IndyPloy: Marty proves himself quite capable of coming up with ways to get himself out of a bind.
** In ''Part I'', when Biff and his cronies tried to run Marty into the back of a manure truck, Marty leaped off of his skateboard and ran through Biff's car.
** He managed to stop a temporal paradox that could destroy all of space-time with a few well-placed sandbags to the head of Biff's goons in ''Part II'':
** Unable to avoid a gunfight, he uses the door of a conveniently-placed stove as a bulletproof vest in ''Part III''.
** Also from ''Part III'', after seeing Clara about to fall from the train with Doc barely hanging on, Marty slipped Doc the hoverboard to help catch her.
* INeedAFreakingDrink: He seems to have this reaction to "parking" with his [[ParentalIncest future mother]] - [[HypocriticalHumor right after he takes the liquor bottle off of her]], he takes a swig of it himself (leading to the SpitTake described below).
* InferioritySuperiorityComplex: Marty is way too eager to prove himself when challenged out of fear of being weak-willed like George.
* InHarmsWay: The first two movies end with a [[AndTheAdventureContinues clear indication]] that his time-traveling adventures are not quite over, and "Part III"'s destruction of the [=DeLorean=] is negated by the AnimatedAdaptation (which represents an AlternateContinuity, [[WordOfGod according to Bob Gale]]). By the IDW comic series, Marty [[VictoryIsBoring has begun to rely on regular time-travel shenanigans just to keep his life interesting]] and grows depressed when new adventures fail to materialize.
* InnocentBlueEyes: Not really innocent, per se - but his big blue eyes do give off the vibe of "Flabbergasted FishOutOfTemporalWater".
* InSeriesNickname: He's got a couple:
** 1955 Doc calls him "Future Boy" when he thinks Marty is just some kid playing a joke on him. He briefly reverts to this nickname at the start of part 3 when he thinks that Marty is a hallucination.
** Needles addresses him as "The Big M" in both of his appearances.
* IntergenerationalFriendship:
** With Doc throughout the trilogy. It's clear that they've been friends for some time by the beginning of the first film.
** With his parents in ''Part I'', and his great-great-grandparents in ''Part III'', although they're all his age or close to it at the time that these friendships form.
** In the animated series, he has quite a friendly relationship with Doc's preadolescent sons, Jules and Verne. Verne in particular seems to like hanging around with him, but even Jules feels comfortable enough with him to vent about his problems with other kids.
* ItsAllMyFault: In the comics, when he believes he's ruined the lives of his alternate selves by interfering with the timeline.
* KidFromTheFuture: In ''Part I''. Although his parents know nothing of who he really is. Lorraine is enamored with him due to his cavalier attitude (and the "Florence Nightingale effect") and George initially thinks he's a pushy pest who keeps following him around.
** Technically a "Great-Great-Grandkid from the Future" in ''Part III''.
* LookBehindYou: Not only does Marty love this, but it almost always works! It's a RunningGag in the 2010 game for Marty to quickly distract someone by pointing behind them and shouting, "WHAT THE HELL IS THAT?!"
* LoserSonOfLoserDad: In the first film, Strickland sneers that Marty comes from a long line of SLACKERS. (Which is unfair, as he's clearly more outgoing than George ever was in the original timeline.)
* LoveAtFirstSight: Says that this happened with him and Jennifer when Doc scoffs at the idea.
* NiceGuy: There's never once a moment where he does anything mean-spirited in the series.
* NiceJobBreakingItHero:
** In ''Part II'', it's his plan to use the almanac that older Biff overhears and goes back in time to tell his 50's self. Leading into the conflict for the rest of the film.
** In the game, [[spoiler:his plan to get Kid Tannen arrested, and his interactions with Edna Strickland and young Emmett makes them fall in love with each other. This little error throws the timeline into jeopardy and prevents the events of the movies from ever happening, creating the Alt!1986 Citizen Brown timeline.]]
* NobodyCallsMeChicken: His FatalFlaw in the second and third movies. Calling him chicken or otherwise suggesting he's a coward causes him, in various timelines, to challenge a gang of bullies, his clearly corrupt friend from high school, and a known Wild West outlaw. In Lone Pine 2015, this is shown to have ruined his life by getting into a car accident that broke Marty's hand and got him sued by the other driver. Thankfully, after some self-reflection, Marty gets over it.
** Becomes a RunningGag in the animated series, as he gets called a chicken once per episode, especially when an ancestor of Biff is involved.
* OnlyKnownByTheirNickname: His actual name is Martin, but everyone (barring Jules) calls him Marty.
* OnlySaneMan: More or less the voice of reason to everybody else's craziness.
* OrdinaryHighSchoolStudent: For a skateboarding rockstar wannabe, he's surprisingly down to earth.
* PapaWolf: In the second movie, Marty posed as his future son Martin to protect him from Griff Tannen's gang.
* TheParagon: The first movie has him inspire others in the 50s to do what's right. All except Biff and his bully gang of course.
* PintSizedPowerhouse: He's only 5'4", but is able to knock out the 6'3" Biff and Buford with a few punches.
* PlayingCyrano: Gives his father George love advice to win Lorraine's heart.
* {{Pride}}: The proper name for his FatalFlaw. He feels he can't back down from a challenge when called "chicken", but as the series goes on this turns out to have serious [[spoiler:and by ''Part III'', near-fatal]] consequences. [[spoiler:Eventually he learns to overcome it after some sound advice from his ancestors, which inadvertently saves his future in the process.]]
* RealMenWearPink: Marty's hot pink hoverboard, which originally belonged to a little girl. For added laughs the little girl favours Griff's more intimidating model.
* RedOniBlueOni: The red to Doc's and George's blue.
* RippleEffectProofMemory: He's the only one (aside from Doc, of course) to remember the events of the Twin Pines timeline after settling down in the Lone Pine timeline, in which his actions in the past dramatically improved the lives of himself and his family. While the films don't dwell on the ramifications of this, the comics deal with [[SurprisinglyRealisticOutcome his eventual existential crisis]] as a result of the shift.
* ScarsAreForever: In the game, [[spoiler:when trying to prove to his parents that he really is their son in an alternate timeline (as the Marty in ''that'' timeline has been run out of town)]] it's revealed that he has a scar on his left knee that he got in a skateboarding accident when he was twelve.
* SirSwearsALot: He's notably much more foul-mouthed than any other character, yelling "holy shit!" a few times, and having "damn" and "hell" as regular words in his vocabulary.
* SoWhatDoWeDoNow: In the comics, after the events of the film trilogy leave life feeling unlivably dull in comparison.
* SpitTake:
** After confiscating Lorraine's liquor bottle, he sees her lighting a cigarette - [[HypocriticalHumor just as he takes a swig...]]
** A RealLife example happened in a [[http://youtu.be/dR_wNXvcZ9g?t=2m9s blooper]] of the same scene - as a prank, the prop bottle was replaced with an identical one with real alcohol in it, causing Michael J. Fox to spray it all over himself and hilarity to ensue.
* SupportingProtagonist: WordOfGod views him as this in the first and third movies, with George and Lorraine getting the most development in ''Part I'', and Doc getting it in ''Part III''.
* TeensAreShort: Michael J. Fox is only 1.63m, which is somewhat below average for a man, but due to his male co-stars being much taller he looks diminuitive.
* ThisIsWrongOnSoManyLevels: Marty often reacts like this when stuff happens with his young mother [[spoiler: and grandmother too in the game, for similar reasons.]]
* TookALevelInDumbass: In the animated series Marty is more impulsive and short-sighted.
* TrademarkFavoriteFood: His drink of choice is a Pepsi Free (though he'll drink any sugar-free alternative if it's not available). In ''Part II'', it extends to his entire family drinking it at dinner.
* TragicHero: Narrowly subverted; his FatalFlaw nearly causes him to [[spoiler: break his hand and ruin his rock star dreams in a race with Needles]] or [[spoiler: get shot by Buford]], [[spoiler: but he learns to overcome those flaws and therefore doesn't fall into tragedy.]]
* TrueCompanions: [[OrdinaryHighSchoolStudent Marty]] and [[ReluctantMadScientist Doc]] have a [[OddFriendship very strange]] but very strong bond. They are separated by interests and [[IntergenerationalFriendship age]], but they would [[HeroicSacrifice sacrifice themselves]] for each other without a second thought. That's during the films. It gets more flagrant after the video game. This trope being more flagrant in the video game could be justified by the fact that Marty befriended a ''teenage'' Emmett Brown in 1931 like he did in 1955 with his parents and in 1885 with his great-great-grandparents.
* UndyingLoyalty: Shows this towards anyone he cares about:
** No matter how much his parents' actions in both the past and present annoy or upset him, he will ''never'' let anyone get away with hurting George or Lorraine in the long run.
** Shows this towards Doc as well. In the first movie, he tried everything he could think of to make sure that Doc found out about his death in the future, and in the third movie, he refused to go straight home to the future once he found out that Doc was killed in 1885, insisting on going back to rescue him despite Doc's explicit directions to the contrary and saving Doc repeatedly from Buford once he got there.
* TheWatson: Marty is bright and has several useful skills, but when it comes to time travel, Doc has to explain everything.
* WhatTheHellHero: Gets called out on by Doc for trying to bring back a Sports Almanac listing all the winners from 1950-2000 in the sequel so he can win money and become a billionaire.
* YoungGun: Subversion in ''Part III''. While he proves to be a skilled quick drawer and shooter thanks to playing video games, he discards the gun when he actually confronts Buford Tannen. Also, Buford might have been far better quick-draw marksman than him. However, Marty had something else up his sleeve in the form of a worn-over stove door.

->'''Played by:''' Michael J. Fox
Son of Marty and Jennifer in the year 2015.

* ButtMonkey: In his regard, he's like teenage George but worse. Whereas George only got bullied and occasionally beaten up by Biff, Marty Jr. is browbeaten into going along with the criminal activities of Griff and his gang.
* FashionableAsymmetry: His left sleeve is noticeably longer than his right due to a broken wrist cuff preventing the size adjust from working properly. In general he doesn't appear to really mind this, indicating he gives little thought to his appearance.
* GenerationXerox: While he physically looks exactly like his father did at his age, personality-wise he's far more akin to the 17-year-old version of George.
* OhCrap: He has this reaction in the roughly three seconds between him suggesting that he ask his father whether to get involved in the robbery, and Griff beating him to a pulp.

* StrongFamilyResemblance: He looks virtually identical to his father, which comes in handy when the 1985 version of Marty Sr. needs to impersonate him.

* GenerationXerox: He looks exactly like George, and his personality isn't far off from him either.
* HappilyMarried: [[spoiler:To Trixie Trotter, who becomes Sylvia [=McFly=].]]
* PunchClockVillain: He only goes along with Kid Tannen's "shenanigans" due to death threats against his life.
* SexyMentor: For Trixie. [[spoiler: Enough for them to even get married.]]

Lorraine's parents and Marty's maternal grandparents. They are seen only in 1955, leaving it unclear whether they are still alive in 1985.
----
* HappilyMarried: They argue a bit but in an affectionate way. We certainly get no sense that they're dissatisfied with their lives, as we do with George and Lorraine in the original 1985.
* {{Housewife}}: Stella seems to be a pretty typical 1950s housewife. As of 1955, she has cranked out five kids and appears to be pregnant with a sixth.
* LikeParentLikeSpouse: Like George 30 years later, Sam seems more interested in the TV than his family, even watching the exact same show.
* ShoutOut: Stella is named after Stella Kowalski from ''Theatre/AStreetcarNamedDesire'', just so that Sam can yell "STELLA!" as a Creator/MarlonBrando reference.
* StandardFiftiesFather: Sam is clearly based on this trope, albeit he's a bit more grumpy than when it's played totally straight.

* AscendedExtra: Heck, he's an ascended ''offscreen character''. He was briefly mentioned in the first movie when Lorraine's celebration of his return from prison was cancelled because he was denied parole. In the comics, an entire arc centers around the question of what put him in prison to begin with, and its effects on the family are explored in more detail.
* CoolUncle: Before he was arrested, he and Marty were very close.
* HonorBeforeReason: Refused to give away [[spoiler: Biff Tannen and his friends]] to get himself out of trouble, although it means he has to serve a 15-year sentence.

'''Dubbed in French by:''' Creator/PierreHatet\\
'''Dubbed in Japanese by:''' Takeshi Aono (home video dub), Takanobu Hozumi (TV Asahi dub), Miyake Yuji (Fuji TV dub)\\
'''Younger Version Voiced in the Creator/TelltaleGames series by:''' Creator/JamesArnoldTaylor
Hill Valley's eccentric scientist, inventor of the [=DeLorean=] time machine and Marty's best friend. He goes along with Marty in all of their adventures through time, fixing any changes to the timeline caused by time travel.
----
* AbsentMindedProfessor: He forgets to shut off the machines in his lab, resulting in a coffee maker with no carafe that squirts water onto an empty hot plate, a toaster that burns the bread to charcoal, and a can opener that dumps can after can of food into Einstein's overflowing dish. When the Libyans show up, he discovers too late that he has forgotten to load the revolver he brought for self-defense. He also forgot to keep a backup stash of plutonium in the [=DeLorean=], which keeps Marty stranded in the past until the storm of '55 takes place.
* AdaptationalBadass: The video game has him ''punch out'' Beauregard Tannen in a [[OneHitKill One-Hit KO]].
* AmbiguouslyChristian: One of the days he sets an example of a historic day to visit is the birth of Christ, [[note]]Though no one really knows the date and based on how shepherds were in the field was more likely in spring than winter.[[/note]] though whether he sees it as much as a historian or believer is unknown.
* AnimalLover: In both 1955 and 1985 he has pet Dogs -- Copernicus and Einstein respectively - that seem to be as fond of him as he is of them. It says something, after all, that he tests a Time Machine (that he knows will work) on Einstein, leaves him safe in a kennel in Part II, and ''returns from 1885 to retrieve Einstein'' once Time Travel becomes possible again. Copernicus, in 1955, sees his master's name on the grave and sits there whining sadly.
* AntiHero: Doc is a force for good throughout the trilogy: he created the [=DeLorean=] time machine for altruistic reasons, and is very committed to protecting the safety and sanctity of the natural timeline. With that much having been said, Doc makes several decisions to achieve his goals that are very ethically questionable. In the first film, Doc gets the plutonium he requires for his time machine by double-crossing terrorists and puts Marty's life in danger, both intentionally (by making him stand in front of a speeding car to get a good shot of the [=DeLorean=]) and unintentionally (when the Libyans come after him for revenge). In the second film, when Doc decides that perhaps bringing Jennifer to the future wasn't a good idea after all, he has very little problem with knocking out a teenage girl and leaving her unconscious body hidden in an alleyway for quite some time. In the third film, when Marty and Doc run out of other feasible ideas they can think of to get home, they eventually decide to steal themselves a whole locomotive so they can get back to the 1980s.
* BadassLongcoat: He wears a long coat in ''Part III'' and also does some rather impressive things.
* BewareTheNiceOnes: Doc Brown is an intelligent, altruistic scientist who spends the entire series trying to do what's right, help his friends better their lives, and who wouldn't hurt a fly. However, the moment he sees Mad Dog and his friends trying to lynch Marty, he promptly shoots the rope and they takes aim right at Tannen's head. He's fully prepared to drop the hammer on him if that's what it takes to save Marty, and Tannen doesn't try to push it. Also a definite case of LetsGetDangerous.
* BigGood: He has only good intentions with time-traveling, wants to set the timeline's right so no one suffers, and is genuinely helpful to Marty in all three movies and sees him as a close friend.
* BunglingInventor: Strictly speaking, the time machines are the only inventions of his that work[[note]] That we see, that is[[/note]]. The time machine is his only invention seen in 1985, and he seems to be a lot more bungling in 1955, but in that 30-year time period, it's possible he was a lot more accomplished. He is apparently a gifted scientist otherwise, enough that he works as a freelance science troubleshooter.
* BunnyEarsLawyer: He may be eccentric but he's also on par with his scientific heroes in terms of intelligence.
* CantHoldHisLiquor: All it takes is a single shot of whiskey, and he's out like a light.

** ''"Great SCOTT!!"'' Similar to "This is heavy!" from Marty, it's a sign that things have gone pear-shaped.
** ''"IfMyCalculationsAreCorrect..."'' Too bad for Doc that they usually aren't.
* CelibateEccentricGenius: He finds the idea of LoveAtFirstSight ridiculous... until he meets Clara in the third film.
* CharacterDevelopment: Goes from believing at the start of the trilogy that "no man should know too much about his destiny" to saying that "the future hasn't been written yet. No one's has. Your future is whatever you make it!" at the end.
* CharacterTics: He often makes grandiose hand gestures while talking. Creator/ChristopherLloyd said he based his portrayal of Doc, in part, on conductor Leopold Stokowski, i.e. Doc is conducting the world.
* {{Cloudcuckoolander}}: He is famous for his quirky and eccentric personality.
* CoolOldGuy: The guy's built a TimeMachine out of a rather poor car, for starters.
* CrazyPrepared: He travels with a briefcase full of money from different time periods, just in case. "Have to be prepared for all monetary possibilities."
* DeadpanSnarker: It's rare, but he has his moments.
-->''[Marty points out his father, who has a "kick me" sign on his back]''\\
'''Doc:''' Maybe you were adopted?
* {{Deuteragonist}}: For the entire series, Doc is the second-most important character. However, he gets far more focus in ''Part III'', to the point that he's the main character of the third movie.
* DiesDifferentlyInAdaptation: In the original trilogy, Doc is shot by the terrorists he conned to get plutonium to power the time machine. For whatever reason, they're absent in the musical and the risk to Doc that accidentally sends Marty back in time is radiation poisoning.
* DiesWideOpen: Subverted towards the end of Part I. His eyes are wide open but it turns out to be a DisneyDeath.
* EinsteinHair: How ''did'' he get his hair to stick out like that? The game expands on this. During the 1931 Hill Valley Science Expo. Young Emmett is driving his flying rocket-powered car, which explodes violently. When Emmett exits the expo, his hair became like his movie counterpart, as a result of the explosion (which he didn't have before). He comments that after that incident, he got banned from the expo for at least 50 years.
** Lampshaded during Doc's cameo in the queue for ''Ride/TheSimpsonsRide''; Krusty has bought the Institute of Future Technology (after Professor Frink accidentally ran over the investor who would've kept the IFT running), and tells Doc he can tear tickets if he gets a haircut. "Fine by me! It takes me three hours every morning just to get it like this!"
* EvenNerdsHaveStandards: Doc is himself an eccentric and something of a social outcast in town, but even he is appalled at just how pathetically socially inept George [=McFly=] is.
* FanOfThePast: Doc is a fan of the Old West, and gets to live in it by the time ''Part III'' rolls around.
* ForScience: His interest in time travel is completely selfless: he speaks in the first movie of its use for historians and scientists. However, he soon recognizes the problems time travel ''will'' cause in unscrupulous hands, and has no problem ordering Marty to destroy the time machine.
* FriendlessBackground:
** At the time of the films, he has only Marty and his pet dogs, because no one in Hill Valley wants to come near "crazy old man Brown."
** Subverted in 1885, where as the town blacksmith he's well-liked by the town he's on a first-name basis with the saloonkeeper and the mayor.
* FriendlySniper: In the third film, he constructed a sniper rifle while in 1885 which he uses to shoot a rope hanging Marty.
* GadgeteerGenius: He's quite adept at adapting technology to the limitations of the time period he's in.
* GentlemanAdventurer: Has shades of this. (Though he had the foresight to try ''not'' to alter historical events.)
* GoingNative: Fits right in with 1885 California.
* HawaiianShirtedTourist: Played with. Doc is rarely seen without a tacky luau shirt, and he ''is'' a tourist. Makes sense since he's allergic to synthetic fabrics and real Hawaiian shirts are made out of cotton.
* HeroesLoveDogs: He has dogs [[ThemeNaming named after famous scientists]], Einstein in 1985 and Copernicus in 1955.
* HeroOfAnotherStory: He leaves to discover the future at the end of the first film, and after he was accidentally sent back to 1885 at the end of the second movie, he's been living as Hill Valley's local blacksmith for almost 9 months.
* HerrDoktor: Played with. Doc has no Germanic accent or notable behaviors, but he mentions that his parents were the 'von Brauns' until WWI.
* HeterosexualLifePartners: With Marty. In the first film, Doc sacrifices himself to save Marty from the Libyans, and Marty returns the favor by ensuring that he gets the news of his impending death. Throughout the entire trilogy, they're by each others' sides, protecting each other and providing the fandom with many crowning moments of heartwarming.
* HotBlooded: Even more so when he's 17. The present Doc admits that he's nowhere near the bravery his past self was.
* IconicAttributeAdoptionMoment: In the AlternateContinuity videogame ''VideoGame/BackToTheFutureTheGame'', his younger self has an experiment explode and it transforms his hair into the Eisteinian wig that we all know and love. This also marks the point that he fully dedicates his life to science instead of the life of law that his father wants for him.
* IfMyCalculationsAreCorrect: When Doc's baby hits 88 miles per hour, you're gonna see some serious shit.
* IndyPloy: More subtly than Marty, but Doc can be surprisingly pragmatic when he needs to be.
* IntergenerationalFriendship: It's a credit to the actors that we, as viewers, don't question why a skater punk and some old guy would hang out together. But just in case you insist in explanations:
** The [[AllThereInTheManual original script]] had a line by Marty explaining that Doc hired him to clean his garage. Marty, being a music aficionado, was impressed with Doc's vintage record collection. The rest is history.
** The screenwriter decided it wasn't necessary to explain how they first met. Doc is a local pariah and a weirdo, and Marty is clearly a rebel. It's inevitable that Marty would snoop around Doc's garage at some point.
** [[WordOfGod Bob Gale himself]] finally gave a rather heartwarming explanation [[http://mentalfloss.com/article/28526/back-future-co-creator-bob-gale-explains-how-marty-and-doc-became-friends over on Mental Floss.]] [[invoked]]
*** The IDW comic book expanded on this in the first issue, showing that in 1982, Needles bullied Marty into trying to steal from Doc's lab. Marty was able to get inside using his wits rather than brute force, which impressed Doc enough to offer him a part-time job as his assistant. He didn't actually need help, but Marty's enthusiasm convinced him to hire the young man on the spot.
** Another explanation could be drawn from the movie -- that their friendship is a StableTimeLoop. Marty and Doc are friends because Marty helped him in the fifties (and in the game, saved him in the thirties), so Doc knew who he was in the eighties and became friends with him, thus leading to him once again do all of those things.
** The two friends over at ''[[Podcast/BlankCheckWithGriffinAndDavid Blank Check]]'' subscribe to the theory that Marty felt the absence of a male role model and proper father figure growing up, and naturally gravitated to Doc, who is in many ways the opposite of George [=McFly=].
* LargeHam: What would you expect from Creator/ChristopherLloyd?
* LiteralMinded: This comes up a couple of times in the first movie, where he takes Marty's use of slang[[note]]"This is heavy!"[[/note]] at face value in 1955. (In context, this takes place in an era when nuclear war between superpowers was starting to look more likely. It's not the stretch it would be now to have worried that we'd be slingin' around bombs to the point of affecting ''Earth's gravity''.)
* LoveAtFirstSight: Though skeptical of it, it comes true when he meets Clara, which is reciprocated. Becomes a bit of a problem when he and Marty need to get [[TitleDrop back to the future]].
* MadScientist: He ''is'' a bit eccentric and goofy, but Doc has kindly intentions.
* MayDecemberRomance: Played with. Historically speaking, Clara was around 60 years older than him, but biologically speaking, Doc was about 30 years older than her when they first meet.
* MeaningfulName: His first name is "Time", pronounced backwards. His ambition is to travel in time.
* TheMentor: To Marty, especially in ''Part III'', when he helps him learn that there's no point in losing his temper whenever somebody calls him "chicken" (or "yellow" in 1885).
* MisunderstoodLonerWithAHeartOfGold: He has the rumors of being a "crazy old man", and Marty was even warned not to go near him, but did so anyway and befriended him, according to WordOfGod. His main purpose with time-traveling is to help mankind with their problems; he refuses to alter it for personal gain, [[WhatTheHellHero which he calls out on Marty for trying to do in the sequel]].
* MysteriousMiddleInitial: What exactly the ''L'' stands for isn't stated until the animated series, when an EvilFormerFriend of his refers to him as "Emmett Lathrop Brown."
* NiceGuy: Doc is an eccentric, mad scientist who was willing to steal plutonium from terrorists to fuel his time traveling car. However, he genuinely cares about Marty and is a relatively decent guy in general.
* OffscreenMomentOfAwesome: Doc's second time machine was built in the Old West and runs on steam, which is a massive upgrade from relying on plutonium, lightning and futuristic technology to power the original time machine.
* OlderThanTheyLook: He's nearly one hundred years old in the game, yet still looks like a man in his sixties. {{Justified|Trope}} by the fact that he took advantage of future medicine to rejuvenate himself and increase his lifespan. [[TooMuchInformation They also replaced his spleen and colon.]]
* OmnidisciplinaryScientist: Aside from inventing a time machine with an onboard nuclear reactor, he's also managed to build a working refrigerator (well, it can produce ice, anyway) using 1885 components[[note]]working refrigeration units actually existed at the time - the truly impressive thing here is that he did it with parts you could find in a podunk hamlet like Hill Valley[[/note]], and a second time machine that runs solely on steam power (again, using components available around 1885). Also, when he meets Clara and lets slip that he's a scientist, he mentions that he's a student of all sciences.
* OnlyFriend: Marty is all Doc has except for his dogs. Doc is a decent and loyal man who happens to have the reputation of being a MadScientist. Marty feels out of place himself but nonetheless knows enough about making friends to have the fellow members of his garage band.
* PapaWolf: To Marty, he draws away the Libyan terrorists' gunfire to him so Marty can get away in ''Part I'' and in ''Part III'', he saves Marty from being hanged and threatens to shoot Mad Dog Tannen in retaliation. To Jules and Verne, Doc goes through a variety of feats in ''[[WesternAnimation/BackToTheFuture Back To The Future: The Animated Series]]'' to protect them such saving Verne from falling to his death from the top of Independence Hall in the episode "Go Fly a Kite" and rescuing both boys from a gang in the episode "Dickens of a Christmas."
* TheProfessor: In the original draft, he'd been called "Professor Brown" before it was recommended that he'd be called "Dr. Brown" or "Doc". This new nickname became so iconic that during the filming of ''Film/TheFrighteners'' years after BTTF, Creator/MichaelJFox kept calling the Judge character "Doc".
* RedOniBlueOni: The blue to Marty's red.
* RichesToRags: As Marty finds out when he's in the 1950's, Doc used to be loaded, but he spent it all on his time travel experiment, reducing him to work as a repairman. Doc, however, doesn't mind as the money isn't something he cares about.
* ScienceHero: One of the rare cinematic heroes who is known for his intellect and courage, but not for being a man of action. That said, he will not hesitate to put his body on the line to protect his friends, and he gradually develops into quite a badass gunslinger in the old west.
* SdrawkcabName: His first two names. His first name Emmett is "time" pronounced backwards, and his middle name Lathrop is "porhtal", as in "time portal".
* SesquipedalianLoquaciousness: Especially in the [[WesternAnimation/BackToTheFuture animated series]]. In the DVD commentary, it's lampshaded that Doc will use a bigger word when he could easily use a smaller word, such as calling a dance "A rhythmic ceremonial ritual" even though the word "dance" was clearly written.
* SophisticatedAsHell: "IfMyCalculationsAreCorrect, when this baby hits 88 miles per hour, [[PrecisionFStrike you're gonna see some serious shit.]]"
* SymbolMotifClothing: He's wearing a shirt decorated with locomotive trains in ''Part II''. The same shirt becomes his bandanna in ''Part III''.
* SupportingProtagonist: In ''Part I''. He serves as Marty's best friend but is merely a scientist who in the past will help him get back to the future at the end. The movie is really about Marty fixing his teenage parents' relationship.
* TookALevelInBadass: His first appearance in ''Part III'' involves him rescuing Marty from being hanged by shooting the rope holding him up, then proceeds to get Buford and his goons to run off. He also figures out how to build a new time machine from scratch while living in the Old West.
* TrueCompanions: [[RidiculouslyAverageGuy Marty]] and [[ReluctantMadScientist Doc]] have a [[OddFriendship very strange]] but very strong bond. They are separated by interests and [[IntergenerationalFriendship age]], but they would [[HeroicSacrifice sacrifice themselves]] for each other without a second thought. That's during the films. It gets more flagrant after the video game.
* UncattyResemblance: Doc and his dogs all have EinsteinHair.
* TheVonTropeFamily: In ''Part III'' Doc explains that his family use to be the "Von Brauns". He goes on to explain his father changed it to Brown because of UsefulNotes/WorldWarI.
* WordOfDante:[[invoked]] Bob Gale guesses that Doc was involved with the Manhattan Project, but became an outcast and spent the remainder of his life trying to invent something beneficial for humanity. Hence the portable nuclear reactor which he sank his entire fortune into. This would also explain his cynical predictions for the future in 1955 ("Of course! Because of all the fallout from the atomic wars!") Became (semi-) canon on the IDW Publishing BTTF comics (written by Gale).

!!Emmett Lathrop "First Citizen" Brown
An alternate Emmett Brown created by Marty's errors in the game. As different from the original Doc as you can get. Considering who First Citizen Brown is, he embodies similar tropes, but to avoid redundancy, the following are either exclusive to First Citizen Brown or ones significantly changed from Doc.

* AbsentMindedProfessor: Less than the original Doc Brown. Thanks to or because of Edna's influence on him.
* AdaptationalHeroism: He is much more sympathetic in the comic book adaption of the game.
* AlasPoorVillain: [[spoiler:Asks Marty for forgiveness before fading away from existence.]]
* AntiVillain: He actually has no idea that he's evil.
* BigBrotherIsWatching: In Episode 3, "Big Brother" is Citizen Brown. [[spoiler:Though it's really Citizen Edna who pulls the strings.]]
* DecoyLeader: He thinks that he's in charge, but Edna's TheWomanBehindTheMan.
* FaceHeelTurn: See WhatTheHellHero below.
* HeroicBSOD: See his MyGodWhatHaveIDone entry below.
* InkSuitActor: The hairstyle design changes reflect Christopher Lloyd's real-life baldness.
* MakeWrongWhatOnceWentRight: But from his own perspective, it's [[SetRightWhatOnceWentWrong the opposite.]] [[spoiler:After he learns that Edna is miserable in the normal timeline, and thanks to his remaining love for her, he sabotages Marty's work convincing his past self to enter the science expo to ensure that he will be together with Edna in the future.]]
* MyGodWhatHaveIDone: Once he realized his wife Edna used him and his science to try to turn Hill Valley citizens into mindless robots.
* ReasonableAuthorityFigure: Unlike Edna, he hears out Marty's case before branding him as a troublemaker for Citizen Plus.
* RedemptionEqualsDeath: [[spoiler: Dies saving Marty from Edna's car assault.]]
* RefusalOfTheCall: Never became the scientist Doc Brown became, instead ruling Hill Valley with an iron fist. [[spoiler:But it's Citizen Edna who pulls the strings.]]
* ScienceIsBad: He blames his science for turning [[spoiler:Edna]] so corrupt in the future. He's wrong, of course, but he's unlikely to listen to reason...
* WellIntentionedExtremist: He wanted to change the world, but he went at it in the wrong way.
* WhatTheHellHero: Calls out Marty on this, because Marty fixing the timeline equals him and his life being erased from existence. He [[TakeAThirdOption takes a third option]].

->'''Played by:''' Creator/MarySteenburgen\\
'''Dubbed in French by:''' Creator/FrederiqueTirmont
A schoolteacher who originally perished in 1885 in a ravine. Doc Brown rescues her during his time in 1885 and remains with her to start a family in that time.

* AdaptedOut: She doesn't appear in the musical, which ends the story after the first movie.
* AlliterativeName: '''CLA'''ra '''CLA'''yton.
* BornInTheWrongCentury: In the "Clara's Story" section of [[ComicBook/BackToTheFuture the comic book]], Clara muses about how she and Emmett are like this, with Emmett fitting in better in the past, and her own desire to leave the past and visit (or live in) the future.
* CatchphraseInsult: In the animated series, her preferred word for someone she dislikes is "buzzard".
* ConvenientlyAnOrphan: The fact that her parents are dead and she's seemingly alone in the world frees her up to leave her era and traverse the timeline with Doc.
* DamselInDistress: Doc saves her from falling in the ravine and later from falling off the train.
* DrivenToSuicide: WordOfGod [[http://bttf.wikidot.com/official-bttf-faq#toc17 suggests]] she might have deliberately jumped into the ravine after Doc was shot by Mad Dog Tannen.
* GeekyTurnOn: "You've read Creator/JulesVerne?", "I ''adore'' Creator/JulesVerne!" Doc's science background also intrigued her.
* InSpiteOfANail: She died falling into a ravine in the original timeline but Doc saved her in the second. WordOfGod says she might have jumped in on purpose after Doc died.
* LoveAtFirstSight: Becomes rather flustered when she first lays eyes on Doc after [[RescueRomance he saves her life]].
* {{Love Interest|s}}: She becomes Doc Brown's love interest after they fall in love at first sight.
* MayDecemberRomance: Clara's in her thirties while Doc is in his sixties. Played with considering she was born nearly a century before he was.
* PluckyGirl: She's crazily determined enough to climb all the way to the train's engine room, despite all the explosions.
* {{Schoolmarm}}: She is Hill Valley's new schoolteacher in 1885. She still dresses like this even in the present.
* SkepticNoLonger: Predictably, she did not buy Doc's initial claim that he was from the future and assumed his love for her was all a lie, until she overhears how truly devastated he was to have lost her heart. She ditches the train and rushes all the way back to his shop to make things right, only to find Doc's time machine model sitting on the railroad set. Realizing the truth, she makes a mad dash to catch him aboard the train.
* TookALevelInBadass: In the animated series, she joins Doc on his adventures and engages in more action.
* UncertainDoom: WordOfGod suggested she might have killed herself in the timeline where Doc was shot but says he'd leave it up to the viewers to decide if that was true
* WomanScorned: When she believes [[CassandraTruth Doc is toying with her]], she calls him out, slaps him, and slams the door in his face.
* WrenchWench: At the end of one comics story, Clara is seen adjusting the armature of the Jules Verne train with a wrench, and other stories imply that she had some hand in assisting Doc with the train's construction.

[[folder:Jules Brown]]
!!Jules Eratosthenes Brown
[[quoteright:340:https://static.tvtropes.org/pmwiki/pub/images/jules_9.jpg]]
->'''Played by:''' Todd Cameron Brown

The elder son of Doc Brown and Clara Clayton. A major character in the animated series, he takes after his father by using big words and having high intellect for a child.

* AdaptedOut: Doc never meets Clara in the musical, so he and his brother don't exist there.
* AscendedExtra: His only appearance in the original films is a brief, non-speaking appearance at the end of the third film. However, he becomes a main character in the animated series.
* BigBrotherBully: His relationship with Verne is fraught with fights, some of them caused by Jules being an InsufferableGenius. "Go Fly a Kite" saw him tell his brother that his non-geeky personality proves he's not a Brown.
* FreeRangeChildren: He (and his brother) frequently take the [=DeLorean=] and gallivant [[ExaggeratedTrope around the time stream]]. Sometimes it's {{zigzagged|Trope}} when Marty is along on a particular adventure.
* IJustWantToHaveFriends: "[[Recap/BackToTheFutureTheAnimatedSeriesS2E7TheMoneyTree The Money Tree]]" has Jules growing tired of being an outcast due to his high IQ and inventing the tree of the title to get attention.
* JerkWithAHeartOfGold: Jules' personality in the animated series. His sibling rivalry with Verne sometimes goes to cruel lengths, but he honestly does care about his little brother and is a decent person in general.
* KidFromTheFuture: He and Verne meet past versions of their parents in multiple episodes.
* NerdyBully: In the cartoon, he often picks on Verne, while also showcasing his superior intelligence.
* NamedAfterSomeoneFamous: His first name is, of course, a reference to Jules Verne.
* NotSoAboveItAll: Jules may be a ChildProdigy and act rather grown-up, he still has a number of more youthful (and goofy) qualities. In "Roman Holiday" and "[[Recap/BackToTheFutureTheAnimatedSeriesS1E12Retired Retired]]", he demonstrates a love of pranks that matches his brother's, and in "St. Louis Blues", he shows that he's fond of roller coasters (even if that's sometimes crossed over with a desire to do science on them).
* OmnidisciplinaryScientist: In one episode, he creates a machine that prints newspapers from the future. In another episode, he creates a money tree.
* PrefersProperNames: Jules always calls Marty "Martin", notably being the only person to do so, as his parents and younger brother all use the nickname. This fits with Jules' tendency towards SesquipedalianLoquaciousness.
* RunningGag: Shared with his brother, a conversational gag that originated in the cartoon and carried over into the IDW comics:
-->'''Jules:''' <says something in an [[SesquipedalianLoquaciousness overly complex or erudite way]], for example: "I am formulating a brilliant concept!">\\
'''Verne:''' <says the exact same thing, but simpler, having failed to understand, for example: "Who cares, what we need is a good idea!">
* SesquipedalianLoquaciousness: In the animated series, he's even more prone to using long words than [[TheProfessor his father.]]
* SiblingRivalry: His and Verne's fights kick off a lot of the episodes.
* SkepticNoLonger: In the comics, when he first sees his father disappear in a time machine. He took it for granted that Doc had been making the whole thing up.

[[quoteright:340:https://static.tvtropes.org/pmwiki/pub/images/verne.jpg]]
->'''Played by:''' Dannel Evans

The youngest son of Doc Brown and Clara Clayton, a major character in the animated series. He's much more of a troublemaker than his brother, and acts his own age.

* AdaptedOut: Doc never meets Clara in the musical, so he and his brother are non-existent.
* AscendedExtra: His only appearance in the original films is a brief, non-speaking appearance at the end of the third film. However, he becomes a main character in the animated series.
* BlackSheep: Verne does not have the same scientific interests or intelligence as his father, though he does have the blond hair Doc had as a younger man (and a bit more common sense). His brother Jules likes to tell him he was adopted. [[SubvertedTrope However]], it's mostly Verne that feels this way (encouraged by his brother); Doc and Clara love him every bit as much as Jules.
* CatchphraseInsult: The cartoon version likes insulting people (especially Jules) with "skunkhead."
* CuteButCacophonic: In the cartoon. He's a cute little tyke, but he doesn't have an indoor voice.
* EmbarrassingFirstName: In "A Verne By Any Other Name", after being bullied about his name, Verne went back in time to convince the real Jules Verne to change his name; failing at that, he travelled back to his own birth to convince his parents to name him something else.
* {{Expy}}: He wears a coonskin cap like Lorraine's younger brother Milton from the first movie.
* FreeRangeChildren: He (and his brother) frequently take the [=DeLorean=] and gallivant [[ExaggeratedTrope around the time stream]]. Sometimes it's {{zigzagged|Trope}} when Marty is along on a particular adventure.
* FunnyBackgroundEvent: Infamously in ''III'', when the actor playing him had to go to the bathroom, and pointed at his crotch to indicate so -- not realizing the camera was rolling.
* IntergenerationalFriendship: Despite the decade or so gap between their ages, Verne gets along quite well with Marty, possibly due to being the odd people out amongst the Browns, most of whom are science nerds.
* KidFromTheFuture: He and Jules meet past versions of their parents in multiple episodes.
* LittleStowaway: His first experience with time-travel in Issue 18 of the IDW comic.
* NamedAfterSomeoneFamous: His first name is, of course, a reference to Jules Verne. It becomes a plot point in one episode, in which teasing makes him perceive it as an EmbarrassingFirstName.
* RunningGag: Shared with his brother, a conversational gag that originated in the cartoon and carried over into the IDW comics:
-->'''Jules:''' <says something in an [[SesquipedalianLoquaciousness overly complex or erudite way]], for example: "Just catenate expeditiously!">\\
'''Verne:''' <says the exact same thing, but simpler, having failed to understand, for example: "How about I follow you, instead?">
* SiblingRivalry: His and Jules's fights kick off a lot of the episodes.
