2015: (slenderman static) collect my fax

Hell Valley/ 1985A: This Marty is canon to the movies, but we never actually see him or know anything about him beyond the life we see around him. Biff becomes his stepfather after George gets killed when he’s 4, and he’s been kicked out of multiple boarding schools and is supposedly in one in Switzerland at the time the movies take place. We also know the state of the world in this timeline, but… that’s all we know. Thus, @chainsaw-headache and @bubbiegummie made this interpretation/design of him, and now we get to speculate what 1985A Marty was like! I linked both of their posts, which go into more depth about him!! He’s also one of Bubble’s Martymania main 3 and has some very interesting interactions with his counterparts. There’s a lot of really really great art of him. Go go go! Seeeee!! #1985a marty

The Draftlings: These Martys are from the earlier drafts of BttF.

by @actuallymartymcfly, #the draftiverse

Fridge/ 1st Draft: To give an overview, he’s more of an asshole than the Marty we got. He pirates movies and he’s called Fridge because he’s from the version of the draft where the time machine was a fridge and required a nuclear explosion to power, before the writers had the thought that children might climb into fridges after seeing the movie and get stuck/die. Einstein is a chimp… I won’t list everything else here because the post goes much more in depth than I could in a brief summary. Go take a look!

Three Pines/ 3rd and 4th Draft: Closer to the Marty we know. His Doc is a hippie. The time machine is the DeLorean we are all familiar, but still uses a nuclear test site to get home. Again, I won’t list everything here because! You! Should! Go read it! Yourself!!!! Because I could not do it justice!! There’s also art!! In the tag!! (By the way, for those of you who have read the novelization, this nuke plot point in the earlier drafts is why that book starts Like That. Whatever version of the script George Gipe had must have still had this opening but didn’t actually use a nuke anymore)

Game[s]: These Martys originate from official BttF games.

[Telltale] Tannenville/ 1986F: Timeline where Kid Tannen never went to jail after changes in 1931. His mafia flourishes and by 1986, the Tannen family runs Hill Valley. This Marty was run out of town in 1984 following a deal that the Tannens would go easier on his dad (who has already been put into a wheelchair by them) if he left. I couldn’t find a design for him, so I made one on the fly (ha)! (I couldn’t really find anything about him, so I guess I could speculate a little…. iiiiiif you want my take on present-day 86F Marty. I think things are probably pretty awful for him, if the Tannens had as far reaching influence as they claim they did. I mean if they had these sorts of connections, they could possibly have prevented Marty from getting any sort of job or discouraged anyone from taking him in, regardless of where Marty went. I think Marty would ended up homeless and just scraping by, and personality wise I think maybe he’d have been the oddest mix of like Twin Pines George and Citizen Brown Jennifer. Like. Idk if you see the vision. The classic Marty stubbornness, but then taken much further to defiance, to a I’m-going-to-vandalize-things-to-stick-it-to-the-world-because-it-sucks kind of level. Then mixed with an extreme case of anxiety and not believing in himself. Aaaand homesick. So, so homesick. I also personally think something similar to what happened to 1985A Doc happened to 1986F Doc, given he was supposedly “Calvin Klein’s” uncle, and who else is going to pay off that $300 debt after “Calvin Klein” disappears? Idk, I really couldn’t find anything on this timeline beyond what happens in the game! I probably didn’t look hard enough. I’m pretty bad at that, I accidentally overlook a lot of things! So I’m so sorry if there was one and I missed it I have sifted through so many AUs 😭) #1986f marty

[Telltale] Citizen Brown/ 1986G by @bubbiegummie: From the Citizen Brown timeline where Doc marries Edna Strickland after changes in 1931 and instead of becoming an inventor, he works with Edna to use technology to create a “perfect” Hill Valley, free of hooligans and disorder. It is a police state and everyone is miserable. Martin is the perfect citizen and has a promising future he has worked hard to solidify. He’s also just as miserable as the rest of this timeline’s Hill Valley, but does believe it to be the “perfect” Hill Valley Edna was striving for. Will do anything to protect it and his future, and as part of Bubble’s Martymania main 3, does not seem to get along well with any of his counterparts. Bubble goes super in depth with his personality and motivations, and there is lots and lots of really great art of him. Go have a look! #citizen martin

[Telltale] Citizen Brown/ CTM [Citizen Time Machine] by @aromantic-ghost-menace: The same timeline as 1986G with a slightly different interpretation. This Martin leans more into the nerd stereotype rather than the teacher’s pet control freak that 1986G is. As such, since Doc is preoccupied running his police state Hill Valley with Edna and uses science to “make things perfect”, the time machine is instead invented by Martin! This AU is distinctly different from Bubble’s, so *both* are worth checking out!!!! Also he’s holding a fidget spinner. If you couldn’t tell what that was. There’s a lot of depth to this AU, and it’s really interesting! A lot of story elements and personality traits have been hammered out and it is 100% worth the read. There’s also quite a bit of art for this one too, so go look! #CTM AU

[Super Adventure Game] Time Loop of Death by @actuallymartymcfly: This is the Marty from the book, Back to the Future Super Adventure Game by Hitoshi Yasuda. It is an interactive book that follows the movie’s plot, but the reader must roll dice and add/subtract a modifier to the result. Much like a choose your own adventure book, there are multiple different endings; this Marty is one who has to go through all/most of the incorrect endings and retry upon death/failure. There is not much to this AU just yet, but we shall patiently wait to see what Leon has in store for him and how he fleshes out! In the meantime, check out 1985PN ;)

Canon adjacent (story differences): These Martys follow canon but diverge at a certain point in the story, either before, during, or after the events of the movies.

Thorn Valley/ 1985PN by @actuallymartymcfly: Marty who follows canon events, except his Needles is significantly more off the rails. This impacts his experiences and personality, leading him to be much more punk and a little faster to fly off the handle. Still the Marty we know and love deep down, but he’s got a lot of backstory changes and development! It’s really interesting and it’s an incredibly in-depth AU, really exploring Marty’s relationship with Needles and how that affects him. There’s a lot of art and comic edits of him, and also so so much more to his story that I couldn’t begin to get into here, so go read read read!!! #pine needles au

1885A by @gloomkeep: This is a Marty whose 1885 became more like 1985A with Buford Tannen basically running the place after killing all of Hill Valley’s marshals and mayor. Marty spends an extra few months in 1885 and it. Doesn’t go super well for him. He and Doc are on the run, and everything is just all round terrible times. Marty watches Seamus die. Clara gets a gun! There is a lot of plot (much much more than I have listed) and many fics for this AU so pop on over and have a look!!!! #1885a

Doomed Pine Twin Pines/ 1985DTP by @futureboiii: Upon returning from 1885, this version of Twin Pines Marty actually does get hit by the train as he tries to jump out of the way, losing a leg in the process. Except, this was not just an unfortunate accident. #BTTF doomed pine AU

Doomed Pine Lone Pine/ 1985DLP by @futureboiii: This version of Lone Pine Marty used his own DeLorean to go back in time to hijack the train that hit DTP Marty with the intention to kill him so he could get his own life back. There’s quite a bit more to this AU, including art, so I’ll leave you to see the rest on your own!! #BTTF doomed pine AU

Canon adjacent (design differences): These Martys follow canon, but have major design differences.

Martee/ Butch!Marty by @bubbiegummie: Marty, but butch! There’s not too many drawings of her but she! Is still worth checking out!!! Go!!

Marie/ Fem!Marty by @fredducinibenson: Marty, but a girl! This is something you gotta see. It’s so awesome. There’s a lot of fantastic art of her (and of other feminized Martys!), I’m always so stunned when it pops up on my feed, go look! #fem marty mcfly

Blarty by @kit-screams-into-the-future: yo listen up here’s a story about a little guy that lives in a blue world and all day and all night and everything he sees is just blue, like him, inside and outside blue his house with a blue little window and a blue pickup and everything is blue for him and himself and everybody around ‘cause he ain’t got nobody to listen (to listen (to listen))

Fishboys: These Martys are aquatic.

(note: octopuses and squids are molluscs, not fish)

MerMarty is an original AU, and the other two are inspired by other media.

MerMarty by @kit-screams-into-the-future: This Marty is an amazing little mermaid. Doc, who is still a physicist but now with the little hobby of fishing, hooks Marty, who pulled on the hook not intending to get caught by it and has to follow for the sake of his hand. It’s a cute story about Marty, who has lived in the ocean his whole life, learning about life on the surface, and Doc getting to learn more about Marty’s kind as well. Obviously I can’t cover the whole story here; The post explains it all, and there are some fantastic comics (as well as amazing art by others), so go check it out!! #mermarty au

Splatoon AU by @mythical-bookworm: Marty that lives in the Splatoon universe! Some really great art here, as well as designs for Jennifer and Doc. It’s a very fun AU idea. I don’t know enough about Splatoon to summarize it well, so go have a look for yourself! #bttfxsplat tag

Luca AU by me: I haven’t done much with this AU besides draw him once and make a silly short comic thing! But he fit into this group too well soo… here he is :) I’m planning to write something for this AU at some point. Maybe.

Cat/ Fox to the Future: These Martys are a tad bit fluffier than in canon.

(Canon-adjacent, design differences)

Fox Marty by @riocinn: Have you ever wanted to see Marty art and content but he’s a fox? YES, you have!!!!!!! Seriously, though, the art is incredible and Rio has some really interesting takes on the movies. And it’s not just Marty, his family have their own unique designs, Jennifer’s a cat, Doc is an owl… the designs suit them all so so well, too. Go check it out! Posthaste!!!

Cat to the Future by @kit-screams-into-the-future: Some really fun anthro designs for the whole BttF cast! Each design really encapsulates the character. You gotta see it to know what I’m talking about so why don’t you head on over? #cat to the future au

Cat to the Future by @hymntoody: Cat Marty! You want to see more of him so bad. You must. I mean, Marty content but he’s a cat?? C’mon… that’s awesome. Lots of great BttF stuff here, including comics and memes, etc. He’s also got designs and content for the other Martys and Martymania. Just a lot of fantastic art! Go look go!!!! #cat to the future au

Pokémon: These Martys are from the Pokémon universe.

Trainer Marty by @blueskyphoenix: This Marty is a Pokémon trainer! He’s got a really cool design, and there’s got interesting in-universe stuff with Doc and Celebi, for those of you who know Pokémon. Even if you don’t, the designs and art are awesome, so go check it out!

Pokémon Mystery Dungeon: Explorers of Time AU by me: Ahahaha. This was mostly just me making Marty (and crew) into pokémon, but it does tie into a PMD2 AU, which has a very BttF-able plot. Basically, amnesiac Marty travelled back in time to stop an apocalyptic future, but uh. Forgot everything, so. Jennifer has to set him back on track. I worked out a bunch of the details. If you’re interested! PMD2 is, in my opinion, the single best game of the entire Pokémon franchise and holds a very special place in my heart, so I loved being able to fit Marty and the BttF story into it. #bttf pmd2 au

Other Media Inspired: These are Martys from BttF AUs that have been inspired by other media.

Vampire Valley/ 1985V by @ghostsagain112: While technically a Lost Boys inspired AU, she has stated herself that that’s misleading; it’s mostly just an original vampire AU! Jennifer and Marty are vampire hunters, and Doc is a bit more mad scientist, accidentally making vampirism a problem though no one believes him. The different Tannens are all just Biff, an immortal vampire, in different getups. Time travelling vampire hunters? Time travelling vampire hunters!!! It’s a very compelling AU with lots of interesting lore, and some really really great art! Go read and look more into it IMMEDIATELY!! #bttf vampire valley au

Steven Universe AU by @kit-screams-into-the-future: Set in the SU universe, Marty is a gem raised by humans. Doc is also a gem, and when Marty meets him he’s like “woah. You’re like me!” Kit has put together a really interesting and in-depth story set in the SU universe, as well as a very good guide/rundown for those who are unfamiliar with SU (so don’t let that discourage you! Even if you don’t know SU, you can still fully enjoy this AU!). But in short, Marty’s a shapeshifting alien and his human family loves him anyway and he gets into all sorts of hijinks with Doc after he meets him. He’s also in trouble for committing the crime of existing. I couldn’t possibly hope to explain it all here, but head on over to see some incredible art and read everything that he’s written for it! #bttfsu au

Danny Phantom AU by @mythical-bookworm: This Marty has a Doc who built a portal to the ghost world… which then killed him. Kinda. Our favorite time travelling future boy becomes half-ghost half-human! There’s both writing and art for this one, so go check it out! #bttf dp au

Psychonauts AU by @madscientists1mp: This Marty gets psychic powers due to the stress of time travelling! Set in the Psychonauts universe, he awards the main character the Electrokinesis badge upon helping him. It’s a really cool idea! Take a look at the AU explanation and art!!!

FrankenMarty AU by @ifihadanickleforeverytime: Frankenstein AU! Doc uses time travel to gather duplicates of Marty to piece back together to create life. So, Marty is the monster, but though initially Doc is his creator, they fall into more of a father/son relationship. Set in 1700s Germany, it’s a really fun premise with some amazing art to go along with it!! Go have a look! #frankenmarty au

Hotline L.A./ 1989HLA by me: This is my Hotline Miami inspired AU! Graphic violence warning. As a quick summary, Marty gets the ability to reset up to an hour upon death, and through a series of events that occur after the main trilogy, he ends up becoming a hitman. I wrote a fic (and I have another one in the works) that describes the descent and then gives him the Walter White special. The complete summary of that fic is in the post linked. If you’re at all interested. He’s my precious evil little killer. My beloved murder Marty. #1989HLA

Spider-man AU by @finnick-draws: This Marty is Spider-man! And his Jennifer is his MJ. Some really great art here!!! Check!! It!! Out!!

Sonic universe Marty by @actuallymartymcfly: This one seems to be (at least at this point in time) primarily a design difference! But there’s other Martymania Martys that have been sonic-ified and they’re all very cool! Go look!!

PAW AU/ Paw Patrol Marty by @biffbulliedmetoo: Set in the Paw Patrol universe! Marty’s a pup who helps Doc with science experiments. Unfortunately, OP hasn’t posted since 2024, and this is the only post about this AU. But once I stumbled across this one it felt wrong not to include it! Have a read!!

Starlight Express AU by @transmascfly: This Marty is an electric engine. Starlight Express is a 1984 musical about a “young but obsolete steam engine, Rusty, that races in a championship against modern locomotives of diesel and electric engines in the hope of impressing a first-class/observation car, Pearl” (thanks Wikipedia). There are some really cool designs for Jennifer, Doc, and many others here! Go check it out! #bttf/stex au

Flash AU by @novaboystars: This Marty is a speedster, which are known to love music, be involved in science, and time travel. So it suits him perfectly! Speedsters are also known for their kindness and love, that’s the power of love, baby ;) It’s a really fun AU idea, and the lore goes deep. So, go check out the post, read all about it, and look at the awesome art!!

Lapse AU by @mythical-bookworm: This Marty is from the Lapse universe! I don’t know anything about Lapse, but from what I’ve managed to gather, it’s set in 2075 (though the AU takes place in 2150?) and there is an entity that goes just by Time that is aware of all disturbances in their domain… you see where this is going. The main character of Lapse, who was once the leader of a nation in a post apocalyptic future, is enlisted to find the time travellers. There are some really interesting details and plot points here, as well as art, so have a look! #lapsexbttf crossover

Original AU: These are Martys that come from original alternate universes.

Fossil Hunters by @carrotsofthepirabbean: This Marty works with Doc as a paleontologist! This is such a fun AU and there is art and fics and the premise is so so good! Go check it outttt!!

Immortal Marty by @madscientists1mp: This Marty is immortal after repeated exposure to the flux capacitor, and also gets stuck in 1885! He ends up losing his memories, becomes very protective of the clocktower, and quite sunburnt. It’s really really interesting so go look!!

The End by @mythical-bookworm: This Marty is navigating a zombie apocalypse. It’s Doc and Marty against the world, and there’s a lot to this story! Really, go have a read! You know you want to!! #bttf apocalypse au

21st century Marty by @theblueskyphoenix: This Marty is from the 21st century! He has a youtube channel where he posts music and covers, and he and Doc make science videos and build PCs. It’s a really fun idea and the design is awesome! Go have a look!!!

Trinity by @daryfromthefuture: AU where Marty gets stuck in the 1940s, and stays with the Doc from that time. An incredible storyline following Marty and Doc during the Manhattan Project, the shenanigans they get up to, as well as the guilt and turmoil that comes with it. Marty does eventually get to follow his music career, we get father-son Doc and Marty, I mean, what more could you want? Check it out!!

Ashen Pines by @rose-of-pollux: This is an AU in an alternate 1971 where the Cold War goes hot and Doc, having worked on the Manhattan Project, has to go on the run. However, because Marty’s family died, Doc gets son. And son makes everything okay even when it’s really not. So with introspective sad Doc plus adorable kid Marty, it’s a really sweet but heartbreaking AU and definitely worth the read!! #Ashen Pines AU Timeline

Kronos AU by @duckidrawzz: This is a Marty who, when he time travelled, gained time powers. There unfortunately isn’t a lot of content for this one, besides one other post, and OP isn’t super active, but it’s still a really interesting read nonetheless!

Roles Reversed by @b33brained: Age swap AU where Marty is Doc’s age and vice versa! Though my drawing kind of implies otherwise (went off of this post), Marty’s actually a musician that made it semi-big in the 60s and is the town crazy person in the 80s. It’s Emmett who makes the time machine still, but would have been unable to if not for his friendship with Marty and the confidence that gave him. It’s a fun AU with a few fics to go with it and some really really great art!!!

Again, I know for a FACT I must have missed so so many of them, but I’m afraid that is the nature of such things, especially when I’m as new to Tumblr as I am… even two months later, the navigation here is not something I am used to and these search features confuse me greatly. I just barely managed to format this, and my Google history is full of “how do you do ___ on tumblr”. So if you’re reading this, and I missed your Marty, I’m so sorry! Send me an ask w the details/ linked post and I’ll draw him (or her👀) as I have this lot.

Additionally, if there’s duplicates of any of these AUs I missed, because sometimes people have similar ideas but the details vary greatly (everyone has their own unique take on an idea and it’s wonderful!), I am also very sorry!! Again, let me know and I’ll draw him!

Splatoon AU by @mythical-bookworm: Marty that lives in the Splatoon universe! Some really great art here, as well as designs for Jennifer and Doc. It’s a very fun AU idea. I don’t know enough about Splatoon to summarize it well, so go have a look for yourself! #bttfxsplat tag

Luca AU by me: I haven’t done much with this AU besides draw him once and make a silly short comic thing! But he fit into this group too well soo… here he is :) I’m planning to write something for this AU at some point. Maybe.

Cat/ Fox to the Future: These Martys are a tad bit fluffier than in canon.

(Canon-adjacent, design differences)

Fox Marty by @riocinn: Have you ever wanted to see Marty art and content but he’s a fox? YES, you have!!!!!!! Seriously, though, the art is incredible and Rio has some really interesting takes on the movies. And it’s not just Marty, his family have their own unique designs, Jennifer’s a cat, Doc is an owl… the designs suit them all so so well, too. Go check it out! Posthaste!!!

Cat to the Future by @kit-screams-into-the-future: Some really fun anthro designs for the whole BttF cast! Each design really encapsulates the character. You gotta see it to know what I’m talking about so why don’t you head on over? #cat to the future au

Cat to the Future by @hymntoody: Cat Marty! You want to see more of him so bad. You must. I mean, Marty content but he’s a cat?? C’mon… that’s awesome. Lots of great BttF stuff here, including comics and memes, etc. He’s also got designs and content for the other Martys and Martymania. Just a lot of fantastic art! Go look go!!!! #cat to the future au

Pokémon: These Martys are from the Pokémon universe.

Trainer Marty by @blueskyphoenix: This Marty is a Pokémon trainer! He’s got a really cool design, and there’s got interesting in-universe stuff with Doc and Celebi, for those of you who know Pokémon. Even if you don’t, the designs and art are awesome, so go check it out!

Pokémon Mystery Dungeon: Explorers of Time AU by me: Ahahaha. This was mostly just me making Marty (and crew) into pokémon, but it does tie into a PMD2 AU, which has a very BttF-able plot. Basically, amnesiac Marty travelled back in time to stop an apocalyptic future, but uh. Forgot everything, so. Jennifer has to set him back on track. I worked out a bunch of the details. If you’re interested! PMD2 is, in my opinion, the single best game of the entire Pokémon franchise and holds a very special place in my heart, so I loved being able to fit Marty and the BttF story into it. #bttf pmd2 au

Other Media Inspired: These are Martys from BttF AUs that have been inspired by other media.

Vampire Valley/ 1985V by @ghostsagain112: While technically a Lost Boys inspired AU, she has stated herself that that’s misleading; it’s mostly just an original vampire AU! Jennifer and Marty are vampire hunters, and Doc is a bit more mad scientist, accidentally making vampirism a problem though no one believes him. The different Tannens are all just Biff, an immortal vampire, in different getups. Time travelling vampire hunters? Time travelling vampire hunters!!! It’s a very compelling AU with lots of interesting lore, and some really really great art! Go read and look more into it IMMEDIATELY!! #bttf vampire valley au

Steven Universe AU by @kit-screams-into-the-future: Set in the SU universe, Marty is a gem raised by humans. Doc is also a gem, and when Marty meets him he’s like “woah. You’re like me!” Kit has put together a really interesting and in-depth story set in the SU universe, as well as a very good guide/rundown for those who are unfamiliar with SU (so don’t let that discourage you! Even if you don’t know SU, you can still fully enjoy this AU!). But in short, Marty’s a shapeshifting alien and his human family loves him anyway and he gets into all sorts of hijinks with Doc after he meets him. He’s also in trouble for committing the crime of existing. I couldn’t possibly hope to explain it all here, but head on over to see some incredible art and read everything that he’s written for it! #bttfsu au

Danny Phantom AU by @mythical-bookworm: This Marty has a Doc who built a portal to the ghost world… which then killed him. Kinda. Our favorite time travelling future boy becomes half-ghost half-human! There’s both writing and art for this one, so go check it out! #bttf dp au

Psychonauts AU by @madscientists1mp: This Marty gets psychic powers due to the stress of time travelling! Set in the Psychonauts universe, he awards the main character the Electrokinesis badge upon helping him. It’s a really cool idea! Take a look at the AU explanation and art!!!

FrankenMarty AU by @ifihadanickleforeverytime: Frankenstein AU! Doc uses time travel to gather duplicates of Marty to piece back together to create life. So, Marty is the monster, but though initially Doc is his creator, they fall into more of a father/son relationship. Set in 1700s Germany, it’s a really fun premise with some amazing art to go along with it!! Go have a look! #frankenmarty au

Hotline L.A./ 1989HLA by me: This is my Hotline Miami inspired AU! Graphic violence warning. As a quick summary, Marty gets the ability to reset up to an hour upon death, and through a series of events that occur after the main trilogy, he ends up becoming a hitman. I wrote a fic (and I have another one in the works) that describes the descent and then gives him the Walter White special. The complete summary of that fic is in the post linked. If you’re at all interested. He’s my precious evil little killer. My beloved murder Marty. #1989HLA

Spider-man AU by @finnick-draws: This Marty is Spider-man! And his Jennifer is his MJ. Some really great art here!!! Check!! It!! Out!!

Sonic universe Marty by @actuallymartymcfly: This one seems to be (at least at this point in time) primarily a design difference! But there’s other Martymania Martys that have been sonic-ified and they’re all very cool! Go look!!

PAW AU/ Paw Patrol Marty by @biffbulliedmetoo: Set in the Paw Patrol universe! Marty’s a pup who helps Doc with science experiments. Unfortunately, OP hasn’t posted since 2024, and this is the only post about this AU. But once I stumbled across this one it felt wrong not to include it! Have a read!!

Starlight Express AU by @transmascfly: This Marty is an electric engine. Starlight Express is a 1984 musical about a “young but obsolete steam engine, Rusty, that races in a championship against modern locomotives of diesel and electric engines in the hope of impressing a first-class/observation car, Pearl” (thanks Wikipedia). There are some really cool designs for Jennifer, Doc, and many others here! Go check it out! #bttf/stex au

Flash AU by @novaboystars: This Marty is a speedster, which are known to love music, be involved in science, and time travel. So it suits him perfectly! It’s a really fun AU idea. Go check out the post and look at the awesome art!!

Lapse AU by @mythical-bookworm: This Marty is from the Lapse universe! I don’t know anything about Lapse, but from what I’ve managed to gather, it’s set in 2075 (though the AU takes place in 2150?) and there is an entity that goes just by Time that is aware of all disturbances in their domain… you see where this is going. The main character of Lapse, who was once the leader of a nation in a post apocalyptic future, is enlisted to find the time travellers. There are some really interesting details and plot points here, as well as art, so have a look! #lapsexbttf crossover

Original AU: These are Martys that come from original alternate universes.

Fossil Hunters by @carrotsofthepirabbean: This Marty works with Doc as a paleontologist! This is such a fun AU and there is art and fics and the premise is so so good! Go check it outttt!!

Immortal Marty by @madscientists1mp: This Marty is immortal after repeated exposure to the flux capacitor, and also gets stuck in 1885! He ends up losing his memories, becomes very protective of the clocktower, and quite sunburnt. It’s really really interesting so go look!!

The End by @mythical-bookworm: This Marty is navigating a zombie apocalypse. It’s Doc and Marty against the world, and there’s a lot to this story! Really, go have a read! You know you want to!! #bttf apocalypse au

21st century Marty by @theblueskyphoenix: This Marty is from the 21st century! He has a youtube channel where he posts music and covers, and he and Doc make science videos and build PCs. It’s a really fun idea and the design is awesome! Go have a look!!!

Trinity by @daryfromthefuture: AU where Marty gets stuck in the 1940s, and stays with the Doc from that time. An incredible storyline following Marty and Doc during the Manhattan Project, the shenanigans they get up to, as well as the guilt and turmoil that comes with it. Marty does eventually get to follow his music career, we get father-son Doc and Marty, I mean, what more could you want? Check it out!!

Ashen Pines by @rose-of-pollux: This is an AU in an alternate 1971 where the Cold War goes hot and Doc, having worked on the Manhattan Project, has to go on the run. However, because Marty’s family died, Doc gets son. And son makes everything okay even when it’s really not. So with introspective sad Doc plus adorable kid Marty, it’s a really sweet but heartbreaking AU and definitely worth the read!! #Ashen Pines AU Timeline

Kronos AU by @duckidrawzz: This is a Marty who, when he time travelled, gained time powers. There unfortunately isn’t a lot of content for this one, besides one other post, and OP isn’t super active, but it’s still a really interesting read nonetheless!

Roles Reversed by @b33brained: Age swap AU where Marty is Doc’s age and vice versa! Though my drawing kind of implies otherwise (went off of this post), Marty’s actually a musician that made it semi-big in the 60s and is the town crazy person in the 80s. It’s Emmett who makes the time machine still, but would have been unable to if not for his friendship with Marty and the confidence that gave him. It’s a fun AU with a few fics to go with it and some really really great art!!!

Again, I know for a FACT I must have missed so so many of them, but I’m afraid that is the nature of such things, especially when I’m as new to Tumblr as I am… even two months later, the navigation here is not something I am used to and these search features confuse me greatly. I just barely managed to format this, and my Google history is full of “how do you do ___ on tumblr”. So if you’re reading this, and I missed your Marty, I’m so sorry! Send me an ask w the details/ linked post and I’ll draw him (or her👀) as I have this lot.

Additionally, if there’s duplicates of any of these AUs I missed, because sometimes people have similar ideas but the details vary greatly (everyone has their own unique take on an idea and it’s wonderful!), I am also very sorry!! Again, let me know and I’ll draw him!

oh shit i was right it is about doc getting picked up for the manhattan project! the comic opens on the california institute of technology, 1943, as helpfully supplied by the text box. i think this is the one where doc shows them his jello cube with a singular mushroom in it. the mushroom is very important. anyways, doc storms into i think his boss’s office and he’s very mad! his boss asks him why he’s not teaching to which he replies this:

gotta search up something rq.

yeah this is funny. [a la shrek they don’t even have dental] he doesn’t even teach a math course

docs mad bc he’s noticed all his other colleagues have been disappearing to contribute to what he guesses is a “top-secret think tank” for the war so what’s he still doing here?? that should be him!! (or in his words, “you should’ve bussed me off ages ago!”) throughout his whole rant about credentials and stuff he’s doing this:

the pose and the face are very silly to me. yeah this guy looks highly qualified to me. checks out

i also love how similar he’s drawn to the video game version of him. i can hear this in his younger self’s video game voice

so his boss is like yeah you’re right there is something going on and we thought about you for it and doc immediately takes this as a confirmation that he’s going and asks “can i bring my dog?” which i thought was cute. the canine assistant is very important to him. his boss goes no wait. we get this explanation :

you can say you think his place is a mess. it’s okay. love the stress on “psychologists” too like damn you really think it’s that worrying

doc is not the slightest bit offended he just goes yeah i get it. but ☝️i have an idea

we cut to:

a very tidy and respectable home! seems he’s cleaned up! they’re like yeah based on what we’ve seen we think you’re fit to come with us. then they step on his mail on their way out which reveals that this isn’t his apartment! it’s his landlady’s! tough luck doc….

doc goes home, not deterred by this in the slightest. he WILL be bussed off to that think tank. he’s put his mind to it and by god is he going to accomplish it. oh weird his apartment lights are on-

GOVERNMENT PEOPLE JUMPSCARE

love the guy on the left’s face like yeah. we broke into your apartment. we’re the government. we can do that

also his apartment isn’t even that bad. look how much floor space is clear! plenty of room to roam still, no problem (the bar is low.) (please ignore the giant death ray)

also he still has the stuff on his walls in 1985! the cat clock, the sax, the giant taxidermy fish

the guy in the back turns around OPPENHEIMER??? what are you doing here…. (we know what he’s doing here) (bomb)

they’re like yeah we knew it wasn’t your house this whole time. we respect the hustle. you’re with us now you’re now officially part of the manhattan project! doc says this is cause for celebration and he pulls out:

THE JELLO.

the mushroom really is perplexing. free my man

and that’s the end actually! i thought it would be longer, i’m surprised there isn’t more. looking at the page count this checks out though.

doc being so eager to get into the project is like.

(he doesn’t know.)

not much on the bingo front today. i assume he got his landlady’s permission to use her house but he also could’ve not so it’s a toss-up to if the square is filled

i’m sure this will be cleared up in a later issue (and by that i mean he’s definitely committing another, more clearly defined crime)
