Characters: Back to the Future


    open/close all folders 

    Marty McFly 

This is heavy!
Played By: Michael J. Fox

  • Action Survivor
  • Adorkable: Not on his father's levels, but he still has his moments. Like in Part III when he realizes that he's alone with a gun, and decides to start pointing it to his reflection and mimics Robert De Niro and Clint Eastwood. All while he's wearing pajamas.
  • Badass: Particularly the way he handles 1955 Biff Tannen.
  • Berserk Button: "Nobody calls me chicken!" This ends up getting him into an accident the day he returns from 1885. (May also qualify as a Noodle Incident, since it didn't appear in the first movie. Though that may just be a coincidence.)
    • He also hates it when his friends or family (specifically George, Lorraine, or Doc) are being abused. Especially by Biff.
  • Beware the Nice Ones: He's very sweet and friendly, but he still has a hell of a right hook and won't hesitate to use it.
  • Big Brother Instinct: He forms one over his own father in 1955, protecting him whenever he needs help. Thanks to that and Character Development on George's part, the latter becomes a better person.
  • Book Dumb: 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?
  • Buffy Speak
    Marty: (looking at a bathysphere) It's some kind of... deep-sea diving thingy.
  • Bully Hunter: Granted, since he's grown up seeing Biff as his father's tormentor, it's not too big a surprise.
  • Butt Monkey: At times.
  • The Call Knows Where You Live
  • Catch Phrase:
    • "Nobody calls me chicken!" Cue Trope Namer.
    • "This is heavy!"
    • "Holy SHIT!"
    • (every time he tries to distract his enemies) "Hey, what the hell is that?!" or "Hey, what's that?!"
    • "Here goes nothing." (In the video game)
    • He also tends to mutter "perfect..." when things aren't going well for him.
    • "Wait a minute..."
  • Character Development: His self-confidence seems to have improved after the events of Part I.
    • In Part III, Marty finally overcomes his Fatal Flaw/Berserk Button, saving himself from getting killed by Buford Tannen and saving himself from becoming a Future Loser by never agreeing to the street race with Needles.
  • Character Tics: His, erm... unusual sleeping position.
  • Chekhov's Skill: Skateboarding, guitar shredding, and (later) arcade shooters.
  • Combat Pragmatist: Kind of necessary when facing guns and men twice your size (sometimes both at once).
  • Compressed Vice: Again, his dislike of being called a chicken. In the second movie, his parents reflect on how this was always his Fatal Flaw. 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.
  • Cool Board: Apparently to make up for the fact that he doesn't have a car, originally; we never see him doing any tricks on it.
  • Cool Loser: Supposedly. The only person we see treating him this way in the original timeline is Strickland, though.
  • Cruelty Is the Only Option: In the game, to save the future, Marty pretty much obliterates Emmett's life in the span of two minutes.
  • Deadpan Snarker: At times.
  • 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.
  • Dork Knight
  • Fatal Flaw: Again, see Berserk Button.
  • Fanservice: A split-second shot of him in purple Calvin Klein underwear. Plus in the third movie you get a nice shot of his butt.
  • Fish Out of Temporal Water: Takes an unusually long time to get fully acclimated to being in 1955. Perhaps because his father wasn't a novelist in his original upbringing?
  • Flanderization: Into The Ditz in Back to the Future The Animated Series.
  • Five-Temperament Ensemble: Sanguine/Choleric.
  • Future Loser: Part II reveals that Future Marty gave up guitaring and ended up a lowly salaryman, stuck working for his high school enemy ( la George). Luckily in Part III, Marty manages to avert the event that led to this timeline, with the implication that he has a better future.
    • Future Badass: If the ending to the Telltale game can be trusted.
  • Guile Hero: He uses his wits as much as his physical ability to solve his problems.
  • The Gunslinger: Thanks to an arcade light gun game, he is an accomplished Quick Draw artist. Though, he does refuse to kill Buford so as not to mess up the timeline.
  • Hair-Trigger Temper: 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 he'll try to punch you out. He seems to have grown out of this by the game, however, after his Character Development in the third movie.
  • Hard Head
  • The Hero
  • Heterosexual Life-Partners: 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.
  • Hidden Depths: He's a lot smarter than he seems.
  • High School Hustler: Downplayed. 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.
  • Hypocritical Humor: In the first movie, Marty takes away Lorraine's liquor bottle, saying that she may regret it later in life. He then immediately starts to drink from it himself, but spits it out when Lorraine starts to smoke.
  • I Know Mortal Kombat: Learned how to sharpshoot from playing an arcade game.
  • Indy Ploy: He's quick at coming up with ways to get himself out of a bind.
  • I Need a Freaking Drink: He seems to have this reaction to "parking" with his future mother - right after he takes the liquor bottle off of her, he takes a swig of it himself (leading to the Spit Take described below).
  • Innocent Blue Eyes: Not really innocent, per se - but his big blue eyes do give off the vibe of "Flabbergasted-Fish-Out-Of-Temporal-Water".
  • Intergenerational Friendship:
    • 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.
  • Kid from the Future: In Part I. Technically a "Great-Great-Grandkid from the Future" in Part III.
  • Look Behind You: Not only does Marty love this, but it almost always works!
  • Loser Son of Loser Dad: 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.)
  • Love at First Sight: Says that this happened with him and Jennifer when Doc scoffs at the idea.
  • Name McAdjective
  • Nice Guy
  • Nice Job Breaking It, Hero: In Part II, its 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, he messes up the timeline so much that he prevents the events of the movies from ever happening. Creating the Alt!1986 Citizen Brown timeline.
  • Nobody Calls Me Chicken: In one timeline, this flaw ruined his life.
  • Only Known by Their Nickname/In-Series Nickname: His actual name is Martin, but everyone calls him Marty.
  • Only Sane Man
  • Pintsized Powerhouse: He's only 5'4" but is able to knock out 6'3" Biff and Buford with a few punches.
  • Playing Cyrano
  • Pride: The proper name for his Fatal Flaw. 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 and by part III, near fatal consequences. Eventually he learns to overcome it after some sound advice from his ancestors. Which inadvertently saves his future in the process.
  • Red Oni, Blue Oni: The red to Doc's and George's blue.
  • Ridiculously Average Guy: For a skateboarding rockstar wannabe, he's surprisingly down to earth.
  • Scars Are Forever: In the game, when trying to prove to his parents that he really is their son in an alternate timeline note  it's revealed that he has a scar on his left knee that he got in a skateboarding accident when he was twelve.
  • Spit Take: After confiscating Lorraine's liquor bottle, he sees her lighting a cigarette - just as he takes a swig...
    • A Real Life example happened in a 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.
  • Supporting Protagonist: Word of God 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.
  • This Is Wrong on So Many Levels: Marty often reacts like this when stuff happens with his young mother and grandmother too in the game, for different reasons.
  • Tragic Hero: Narrowly subverted; his Fatal Flaw nearly causes him to break his hand and ruin his rock star dreams in a race with Needles or get shot by Buford, but he learns to overcome those flaws and therefore doesn't fall into tragedy.
  • True Companions: Marty and Doc have a very strange but very strong bond. They are separated by interests and age, but they would 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.
  • Undying Loyalty: 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.
  • The Watson: Neither unskilled nor unintelligent, but can't hold a candle to Doc.
  • What the Hell, Hero?: 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.
  • Young Gun: Subversion in Part III.

    Emmett Lathrop "Doc" Brown 

  • Absent-Minded Professor
  • Adorkable: Especially in Part III, when he sees Clara at the dance.
  • Age Lift / Dawson Casting: Christopher Lloyd was only 48 when he filmed the role for the 71 year old Doc Brown. Probably done on purpose so when Marty goes back to 1955 and meets the 41 year old Doc Brown they look the same, except for aging make-up in 1985, which was dropped in the other parts as Doc underwent a rejuvenating process. They also replaced his spleen and colon.
  • Badass Longcoat: In Part III.
  • Berserk Button: Two, each corresponding to an important person in his life.
    • When Buford "Mad Dog" Tannen implies he's going to sexually assault Clara, Doc wrestles away from Tannen's Mooks, curses at him, and strides forward like he's about to start something.
    • When Tannen shoots Marty and then laughs about it, Doc looks like he's about ready to bite his head off.
  • Big Good: 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.
  • Bungling Inventor: Strictly speaking, the time machines are the only inventions of his that worknote .
  • Bunny-Ears Lawyer: He may be eccentric but he's also on par with his scientific heroes in terms of intelligence.
  • Can't Hold His Liquor: All it takes is a single shot of whiskey, and he's out like a light.
  • Catch Phrase: "Great SCOTT!!"
  • Celibate Eccentric Genius: He finds the idea of Love at First Sight ridiculous...until he meets Clara in the third film.
  • Character Development: 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.
  • Cloudcuckoolander: He is famous for his quirky and eccentric personality.
  • Cool Old Guy: The guy's built a Time Machine out of a rather poor car, for starters.
  • Deadpan Snarker: 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: Although, Doc is arguably the main character of the third film.
  • Einstein Hair: How did he get his hair to stick out like that? The game expends on this. During the 1931 HV Science Expo. Young Emmett is driving his flying rocket powered car, which explodes violently. When Emmett exits the expo, his hairs 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.
  • Fan of the Past: Particularly the Old West.
  • For Science!: Though he's quick to see the problems time travel might cause, and has no problem ordering Marty to destroy the time machine.
  • Five-Temperament Ensemble: Sanguine.
  • Friendless Background: 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."
  • Gadgeteer Genius
  • Gentleman Adventurer
  • Going Native
  • Hawaiian-Shirted Tourist: Played with. Doc is rarely seen without a tacky luau shirt, and he is a tourist.
  • Herr Doktor: Doc technically falls under this, as his father is German.
  • Heterosexual Life-Partners: 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.
  • Hot-Blooded: Even more so when he's 17.
  • If My Calculations Are Correct: When Doc's baby hits 88 miles per hour, you're gonna see some serious shit.
  • Indy Ploy: More subtly than Marty, but Doc can be surprisingly pragmatic when he needs to be.
  • Intergenerational Friendship: 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.
    • The 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.
    • Bob Gale himself finally gave a rather heartwarming explanation over on Mental Floss.
      • Another explanation could be drawn from the movie - that their friendship is a Stable Time Loop. 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.
  • Large Ham: What would you expect from Christopher Lloyd?
  • Literal-Minded: This comes up a couple of times in the first movie, where he takes Marty's use of slangnote  at face value in 1955.
  • Love at First Sight: 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 back to the future.
  • Mad Scientist: Although he's well-meaning, both to Marty and humankind.
  • May-December Romance: 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.
  • Meaningful Name: His first name is "Time", pronounced backwards. His ambition is to travel in time.
  • Misunderstood Loner with a Heart of Gold:
    • 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 Word of God. His main purpose with time-traveling is to help mankind with their problems; he refuses to alter it for personal gain, which he calls out on Marty for trying to do in the sequel.
    • Subverted in 1885, where as the town blacksmith he seems to be well-liked by the town, where he's on a first name basis with the saloonkeeper and the mayor.
  • Older Than They Look: He's nearly one hundred years old in the game, yet still looks like a man in his sixties. Justified by the fact that he took advantage of future medicine to rejuvenate himself and increase his lifespan. They also replaced his spleen and colon.
  • Omnidisciplinary Scientist: Aside from inventing a time machine with an on-board nuclear reactor, he's also managed to build a working refrigerator (well, it can produce ice, anyway) using 1885 components, 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.
  • Only Friend: Marty.
  • The Professor: 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 The Frighteners years after BTTF, Michael J. Fox kept calling the Judge character "Doc".
  • Red Oni, Blue Oni: The blue to Marty's red.
  • Reluctant Mad Scientist
  • Sdrawkcab Name: His first two names. His first name Emmett is "time" pronounced backwards, and his middle name Lathrop is "porhtal", as in "time portal".
  • Sesquipedalian Loquaciousness: Especially in the 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.
  • Sophisticated as Hell: "If My Calculations Are Correct, when this baby hits 88 miles per hour, you're gonna see some serious shit."
  • Symbol Motif Clothing: He's wearing a shirt decorated with locomotive trains in Part II. The same shirt becomes his bandanna in Part III.
  • Took a Level in Badass: 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.
  • True Companions: Marty and Doc have a very strange but very strong bond. They are separated by interests and age, but they would sacrifice themselves for each other without a second thought. That's during the films. It gets more flagrant after the video game.
  • The Von Trope Family: 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 World War One.
  • Word of Dante: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!")

    Lorraine Baines-McFly 
Played By: Lea Thompson

  • Broken Bird: In 1985-A.
  • Former Teen Rebel: Rebel might be pushing it a bit, but she's clearly a little rougher in 1955 than the nice girl image would have you believe.
  • Five-Temperament Ensemble: Sanguine.
  • Gag Boobs: Biff-A made Lorraine-A get some by 1985-A; she doesn't enjoy them.
  • Guess Who I'm Marrying?: Biff in 1985-A.
  • Happily Married: To George. Disappointed with him in the original 1985, but clearly their relationship is in better shape after Marty 'fixes' things.
  • High School Sweethearts: With George.
  • I Was Quite a Looker: Very much. Marty is shocked by Lorraine's real attractiveness when he meets her in 1955. She does retain much of her good looks once the timeline is altered.
    Lorraine: My name's Lorraine, Lorraine Baines.
    Marty: Yeah... but you're ho... you're so h... you're so... thin!
  • Lady Drunk: In the original 1985. Even more so in 1985-A. And in the Citizen Brown timeline in the game.
  • Ms. Fanservice: At least in 1955.
  • No Doubt The Years Have Changed Me: The difference between the Lorraine of 1973-A and 1985-A is downright jarring.
  • Parental Incest: Has a crush on Marty in the first film - much to his horror. Becomes a major problem.
  • Playing Gertrude: Lea Thompson is just nine days older than Michael J. Fox. Though it does make perfect sense, as for most of the first film (intended as a one-shot story at the time) she's the same age as Marty.
    • Stranger is that she's actually three years younger than Wendy Jo Sperber, who plays her teenage daughter in the film series.

    George McFly 
Played By: Crispin Glover, Jeffrey Weissman

  • Adorkable: 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.
  • Berserk Button: When Biff pushes Lorraine to the ground, it prompts George to react with violence for probably the first time in his entire life.
  • Chivalrous Pervert: 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 Attempted Rape 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.
  • Eating Lunch Alone: George sits by himself at the cafeteria during lunch in 1955, writing ideas for his stories.
  • Extreme Doormat: Before taking a level in Badass.
  • Fake Shemp: In the sequels, especially Part II.
  • Flashback with the Other Darrin: 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.
  • Five-Temperament Ensemble: Phlegmatic.
  • Happily Married: To Lorraine.
  • Hollywood Nerd: To the nth degree, before time got altered, at which he veers into Nerds Are Sexy.
  • Kick Me Prank: George is the victim of a particularly cruel prank when some of Biff's friends tape a sheet of paper with the words "KICK ME" on it on his back.
  • Most Writers Are Writers
  • Nerds Are Sexy: 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 Hollywood Nerd.
  • The Peeping Tom: In 1955 and the Citizen Brown timeline of the game.
  • Playing Gertrude: Glover is actually 3 years younger than Michael J. Fox. (averted with Weissman, who is 3 years older). Justified for the same reason this trope is listed in Lorraine's list.
  • The Southpaw: An early draft had George discover he could punch very strongly with his left hand. The final film has George's desire to protect Lorraine cause him to unleash his inner strength, but close observers might notice he knocked out Biff by punching him with his left hand.
  • Took a Level in Badass: Marty basically helps him rise to this point. As soon as Lorraine is shoved to the ground, the fire is lit.
  • You Leave Her Alone: Said word for word by George.

    Biff Tannen 
What are you looking at, butthead?!
Played By: Thomas F. Wilson

  • Arch-Enemy: To the McFly Family in general, but mostly Marty in the first movie.
  • Berserk Button: He really hates manure. When Marty told him he heard about the manure incident in 1985-A he seemed more angry than confused.
  • Big Bad: Of Parts I and II.
  • Bitch in Sheep's Clothing: 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.
  • The Bully: Biff to George, and to Marty, and to Lorraine.
  • The Caligula: In 1985-A.
  • Cannot Tell a Joke: Biff is constantly, err, biffing his attempts at wordplay with lines like "Why don't you make like a tree and get out of here"note  and "That's as funny as a screen door on a battleship."note  Presumably everyone is too afraid of him to correct him. He is berated for this by his older self in the second movie.
  • Can't Get Away with Nuthin' : That's two coats of wax, Tannen!
  • Catch Phrase:
    • "Hello! Hello! Anybody home?! Hey, think, McFly, think!"
    • "Butthead!"
    • "Hey McFly!"
    • "How about you make like a tree and get out of here?"
  • Corrupt Corporate Executive: 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.
  • Egopolis: Alternate Hill Valley is a gigantic Shrine to Self. The front of his casino (formely the Clock Tower) is a museum dedicated to Biff's life, with a life-size wax statue and film reel describing his rapid rise to fortune.
  • Evil Is Petty: Exhibit A — Stealing a ball from some neighborhood kids and hurling it onto a nearby roof. And then he strolls away cackling to himself.
    • 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.
  • Evil Laugh: Icing on the cake.
  • Fake Ultimate Hero: In 1985-A, thanks to Grey's Sports Almanac.
  • Five-Temperament Ensemble: Choleric.
  • Freudian Excuse: His grandmother sounds like a case.
    • In the Telltale game, his father is revealed to be a notorious bootlegger.
  • Future Loser: 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.
  • I Hate Past Me: "It's LEAVE!! You idiot! 'Make like a tree and leave.' You sound like a damned FOOL when you say it wrong!"
  • In the Blood: 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.
  • Jerkass: 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.
  • Malaproper:
    • In Part II:
    Young Biff: [to old Biff] Now why don't you make like a tree and get outta here.
    Old Biff: ([slaps young Biff]) It's "LEAVE", you idiot! "Make like a tree and LEAVE". 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) That's a 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!
    Buford's Henchman: It's "dog", Buford, "shoot him down like a dog".
  • Large Ham
  • Mean Character, Nice Actor: Thomas F. Wilson based Biff on his own experiences being bullied. In high school, he was more like George McFly.
  • Murder the Hypotenuse: In 1985-A, to George McFly.
  • No Celebrities Were Harmed: Word of God says the 1985-A version of Biff was inspired by Donald Trump. The portrait in Biff's office was even based on one of Trump.
  • Older and Wiser: 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.
  • Our Founder: Has a wax statue of himself standing in 1985-A's museum.
  • Outdated Outfit: In 1985-A, he and his gang seem to fit in more with the The '70s than The '80s.
  • Retgone: A deleted scene from Part II shows Old Biff fading away when he returns to 2015. 1985-A Lorraine apparently shot him some time in the mid-90s.
  • Schoolyard Bully All Grown Up: 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.
  • Screw the Rules, I Have Money!: In 1985-A.
  • Villainous Breakdown: 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.
  • Villainous Crush: For Lorraine.
  • Villain with Good Publicity: In 1985-A, he's even got his own museum dedicated to his life story.
  • Would Hit a Girl: In the first film, he pushes Lorraine to the ground, and in the alternate 1985 of part 2, he abuses her along with Marty, among other things making her get breast implants.
  • You Killed My Father: He killed George, Marty's father, in 1985-A.

    Jennifer Parker 
Played By: Claudia Wells, Elisabeth Shue

  • Agent Mulder: 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).
  • All Girls Want Bad Boys: In the alternate!1986 in the Telltale game, 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.
  • The Cheerleader: Averted. It's implied in Part II that she may have been a cheerleader in high school (a maroon and white school jacket can be seen in the closet she's hiding in in 2015, with the name "Jennifer" and an emblem consisting of a megaphone over the "HV" letters), but she's the Girl Next Door type, and doesn't seem like an Alpha Bitch or The Ditz as is usually seen in this trope.
  • The Chick: You get the feeling that there's more to her, but the plot of Part II forces her into this role.
  • Deadpan Snarker: In the game. Well, the punk-rock delinquent version of herself, anyway.
  • '80s Hair: Especially with her first actress.
  • Five-Temperament Ensemble: Phlegmatic.
  • Flashback with the Other Darrin: It's even the page image!
  • Good Girl Gone Bad: In the game, she's a bitchy, sarcastic, delinquent rocker in the alternate-1986; this is implied to be a form of rebellion against Citizen Brown's rule.
  • Guest Star Party Member: 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.
  • Girl Next Door
  • High School Sweethearts: 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 Happily Married. Lorraine even says that she thinks that she married her son out of pity (and this is to her own granddaughter)! 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 Character Development.
  • In-Series Nickname: Is called "Jen" a couple of times by Marty in Part III and in the game.
  • The Load: Bob Zemeckis and Bob Gale never had a character development in mind for her, stating that had they planned to make a sequel to the original film, they would not have put "the girl" in the car at the end. Sure enough, less than five minutes into Part II, she's sedated and pretty much spends the rest of the series that way. Her actresses aren't even given top billing in the film credits, even though those who play even smaller roles are.
  • Locked Out of the Loop: 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.
  • Love at First Sight: With Marty, according to him when explaining that the trope is possible to Doc.
  • Satellite Love Interest: 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.
  • Secret Keeper: She becomes this once Marty tells her about (and shows her whats left of) the Doc's time machine.
  • Static Character: Through no fault of her own, she comes off as this.

    Clara Clayton 

Played By: Mary Steenburgen

    Vice Principal Gerald Strickland 
Played By: James Tolkan

    Buford "Mad Dog" Tannen 
Played By: Thomas F. Wilson

  • Badass Mustache
    • He was shown with a Beard of Evil in the 1985-A Biff's Museum video in Part II, because it was an early makeup test. Word of God said if they had the time, they would've switched that image with one featuring his final appearance.
  • Berserk Button: 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, every single person in the saloon either silently runs away or makes themselves scarce.
  • Chekhov's Gunman: He's first mentioned in the video playing in Biff's Museum in 1985-A.
  • Disproportionate Retribution: 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.
  • The Dreaded: 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.
  • Evil Has a Bad Sense of Humor: He thinks hanging Marty and later shooting him are funny.
  • Hair-Trigger Temper: One of the reasons he's nicknamed "Mad Dog", and a major reason why everyone is scared of him.
  • In the Back: 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.
  • Identical Grandson: A bit tricky to pin down the usual features of a Tannen through that mustache, but he has 'em.
  • Jerkass: Well, he's a Tannen. What else would you expect at this point?
  • Malaproper: "I'll hunt you and shoot you down like a duck." "It's dog, Buford."
  • Mean Character, Nice Actor: Again, he's played by Thomas F. Wilson, so Biff's character traits are seen with Buford.
  • Names to Run Away From Really Fast: "Mad Dog" think this is a bad guy?
  • Politically Incorrect Villain: "He once bragged that he'd killed 12 men, not including Indians or Chinamen."
  • Would Hit a Girl: And did it to Clara, which roused Doc's ire considerably.

The 2010 Game

    Edna Strickland 

Sister of Gerald Strickland. A Crazy Cat Lady Marty meets in Episode 1. 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.

  • All Girls Want Bad Boys: In the game finale, with Kid Tannen, of all people.
  • Big Bad: Of the game.
  • Catch Phrase:
    • "It's a fact, look it up."
    • "Hooligans!"
  • Crazy Cat Lady: The original 1986!Edna and Crazy, Old 1931!Edna.
  • Cloudcuckoolander: By the time Episode 5 rolls around, Marty exclaims, "Jeez, that lady was always a loon!"
  • Epic Fail: 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.
  • Evil Old Folks

    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.

    Irving "Kid" Tannen 

Biff Tannen's father and a famous mob boss in 1931's Hill Valley. Owner of the Speakeasy that was blown the same year.

    Trixie Trotter/Sylvia Miskin - McFly 
Kid Tannen's singer and girlfriend. As well as Marty's grandmother, George's mother and Arthur's wife

    Arthur McFly 

Marty's grandfather and George's father. Almost George's spitting image.

  • Adorkable
  • All There in the Manual: The novel says that Arthur went to WW1 but was discharged for fraudulent enlistment because he lied about his age before he got the chance to see combat. Arthur returned home without even firing a single shot and became a laughing stock. This event destroyed his self-confidence.
  • Extreme Doormat: Like George, his future son, but overall, his life is less miserable than George's was.
  • Generation Xerox: He looks exactly like George.
  • Happily Married: To Trixie Trotter.
  • Sexy Mentor: For Trixie
