  • For all your HoneyGoGo needs. They do them canonical, they do them AU, they do them adorable and in-character, and they do tastefully done intimacy.

Becky Blue Eyes ((also found here: Becky_Blue_Eyes))

  • Recommended by: LittleMissStarRider
  • This author has a series of connected Big Hero 6 stories called the "Nakama Maintenance Workshop 101" series on both fanfiction.net and Archive of Our Own. These stories focus on a sibling relationship between Hiro Hamada and Abigail Callaghan, AU scenarios of Big Hero 6, and LOTS of tragedy and overall feels. Each story is marked with spoilers and certain chapters are marked with trigger warnings for things like gore, self-harm, etc.
  • Special note for Five Alarm Death March ((the first entry in the Archive of Our Own link), which is perhaps one of the darker and sadder AU fics I've read in the Big Hero 6 fanfic community.

    General Fics 

Stories focused on the family and the friendly relationships of the cast. Plot-focused stories or light day-in-the-life stories. Pretty much anything that isn't focused on romance.

5 Times Hiro Still Had a Big Sibling, 1 Time he was a Little Brother by Sick Twisted Mind

  • Recommended by: Anemo 1, Ellowen
  • Status: Complete
  • Synopsis: Being a 13-year-old is hard, even harder when you're in college, hardest when you're a superhero. It's a good thing Hiro has someone(s) looking out for him and time to still play the role of a little brother.
  • Comments: A very heartwarming look into the deeper relationships between Hiro and his five friends. A series of six snipplets that show that you don't need to be blood-related to be a sibling.

Fox-face & Flames by tykimikkity

  • Recommended by: Madam Reg
  • Status: Complete
  • Synopsis: Another mask-wearing hero arrives in San Fransokyo. Having no qualms about killing, this man appears to be more of an adversary than an ally to the city's six heroes. Putting that aside, something about this fox-masked, anti-hero seems melancholy and familiar... alive/anti-hero!Tadashi
  • Comments: Reading this story will better your life by 20%. It explores topics such as amnesia and it does have a moderately heavy usage of OCS, but they're refreshing and fun to read about. Everybody is in character, except Tadashi, but there's a reason for that which will have you drowning in feels. The first few chapters are somewhat short, but the more recent ones are lengthier. Definitely worth the read.

Nii-chan and Birthday Gifts both by Latiwings

  • Recommended by: Anemo 1
  • Status: Complete
  • Synopsis: Nii-chan is another piece where each of Hiro's friends show how they can dedicate themselves towards him and has an interesting, if not slightly far-fetched hook at the end. Birthday Gifts is a semi-sequel where the team prepares Hiro a surprise birthday party and get a little competitive over gifts for him.
  • Comments: The writing can do with a bit of a tune-up, and like I said, the ending of Nii-chan can be a bit hard to swallow, but both stories nail the characters. It's an interesting read considering how this author handles the hook at the end of the first story.

Dog Days by murphystar

    • Note: murphystar doesn't have the story set as complete, but it can read like a oneshot.

Differences by ChocolateSyrup

  • Recommended by: fanfiction000
  • Status: Complete
  • Synopsis: After a freak accident, Hiro and Baymax (literally) learn to live in each other's shoes.
  • Comments: A hilarious, thought-provoking and heartfelt story that further explores the relationship between Hiro and Baymax.

Malignant Butterfly Infestations: A Case Study by ketren

  • Recommended by bookwormgal
  • Status: Complete
  • Synopsis: The Hamada family has a long history of genius, but it also has a history of self-sacrifice. Baymax intends to ensure that Hiro doesn’t follow the family tradition in that respect - even if Hiro appears to be fighting him the whole way.
  • Comments: An amazing story from Baymax's point of view that continues to show Hiro's behavior after the film as he continues to deal with his brother's death.

Memories by dewdropzz

  • Recommended by pretentiousPeanut
  • Status: Dormant
  • Synopsis: A man. A male organism. Height: 6'1". Weight: 165 lbs. Black hair. Brown eyes. Approximately 21 years old. This was the first person I ever saw. The first third of the movie (and a bit before the beginning) written in Baymax's POV. To quote dewdropzz, "This story reads a lot better if it's imagined in Baymax's voice, just sayin". It's short and most of the dialogue is from the film itself, though Baymax's inner thoughts are written extremely well.

From the Ashes of Grief by Uniasus

  • Recommended by kilala2tail
  • Status: Completed
  • Synopsis: The public attention Big Hero 6 received after the battle is not something Hiro wants. He just wants to curl up in his room and cry. But his friends won't let him, Tadashi won't let him, and he really would hate it if he went down in history as 'the baby hero'.
  • Comments: A beautifully done fic showcasing Hiro's healing process as he works through the loss of both Tadashi and Baymax, what it takes to be a hero, and finding his place in the world.

Betwixt the Blackout Curtain by Ikira and SpiritusRex

  • Recommended by kilala2tail
  • Status: Completed
  • Synopsis: Tadashi Hamada assumed, like most people, that once you died that was it. You're done. End of story, do not pass GO, do not collect $200, everyone go home. He’s wrong, of course. But Tadashi will have to learn fast because an evil spirit named Yokai will soon arrive and threaten everything he cares about…
  • Comments: Part one of Tadashi's Guide to the Other Side, this story has a well-done mix of technological and supernatural elements that are used to add an interesting twist on the events of the movie from Tadashi's viewpoint, with beautiful artwork to back it up throughout the story.

You Have To Let Me Help You by ItalianPrincess92

  • Recommended by: Bookyboo
  • Status: Dormant
  • Synopsis: Hiro has been distancing himself from his friends and family, and Tadashi won't rest until he finds out why. When he learns the truth, he will do anything to heal his brother and put that smile back on his face. Triggers: Rape/Depression/Self-harm/PTSD

Till I'm Gone by Sora Matasuki

  • Recommended by: Andre Brachio Toothless
  • Status: Dormant
  • Synopsis: Two years before the start of the movie, the Hamada family was subject to a tragedy that would shake Tadashi's perception on his actions and life, forever. Hiro is struggling to fit in at High School, and his actions will shape the course of their family, forever. After all, something had to spark Baymax into being, right? Triggers: Depression/Bullying/PTSD/Self-harm/Suicide

Twist of Fate, AO3 link by WillowBlueJay17

  • Recommended by: 2heartgirl, Ellowen
  • Status: Complete
  • Synopsis: A small twist of fate can change quite a lot about a story. But, in the end, a brother still grieves. A story that looks to offer a different but familiar approach to the story if a certain something had happened differently.
  • Comments: A fanfic that looks at the idea of what would happened if Hiro died instead of Tadashi. Everyone is in-character and the relationship between the Hamada brothers is expanded beautifully in the early chapters. It's worth a quick check at least. Complete at 15 chapters, and absolutely heartbreaking.

I'll Try to Picture Me Without You But I Can't by songdreamer2016

  • Recommended by: Michael 2608

The Only Pay-Off (For Having Any Faith) by Hedgi

  • Recommended by: kilala2tail
  • Status: Completed
  • Synopsis: Gogo called it "intuition," Wasabi called it "luck," Honey Lemon called it "big brother instinct", and Fred called it "A real-life super-power." Tadashi Hamada called it "ten years of experience." And "access to tracking devices." No matter what, Tadashi will always protect his brother, would do anything for his brother—even help a villain with a revenge plot like something out of Fred's comics.
  • Comments: Also found on FF.net, this is one Alive!Tadashi fic that hits all the right notes. Includes, to quote the author - "Glimpses into other character's lives, Aunt Cass's past, and the power of friendship and family. Canon compliant until the fire, then all bets are off.

There Are (no) Dead Ends, AO3 link by Fieryflowers

  • Recommended by: Michael 2608

  • Synopsis: It is said that when your parents die, you lose your past. When your spouse dies, you lose your present. And when your child dies, you lose your future. However, when your sibling dies, you lose your past, present, and future. [AU where Hiro dies and Tadashi forms the superhero team]
  • Comments: engaging story, but there are a lot of tense changes—sometimes in the same paragraph— that can be pretty jarring. And the "character development" brought on by the AU feels a bit out of left field and pretty OOC, like Tadashi straight up murdering people. Still, has some interesting concepts—Ellowen

So could he really be blamed for what he had chosen to do? He had motives; of course...people always do. But his motives were good ones, surely? For him, at least. For others, it was not suffice to say. For others, this whole thing would be a living nightmare. One they could not possibly wake up from. And for a young boy, with his whole life in front of him, it might even be an ordeal that he would not survive.

The Pulse by marvel1015

  • Recommended by: kittyface44
  • Pairing: Hiro/OC
  • Status: Complete
  • Synopsis: This story takes places a year after the events of the first movie. Hiro has continued on with his life at SFIT, until he meets a 15 year old girl named Akria Tanaka who, like him is a prodigy. They hit it off almost instantly, and Hiro soon introduces her to his circle of friends. After being rescued by the Big Hero 6 team one day, Akria is inspired to become a superheroine of her own league. However, when a tragic event turns her life completely upside-down, she'll end up turning to the team of superheroes for help. And could there be more than just friendship going on between Hiro and Akria?
  • Notes: marvel1015's OC, Akria is very interesting. She is almost like Hiro in some ways, but ultimately has her own personality. The story itself is one of those where Hiro meets a girl his own age and the two fall in love, but it is portrayed very realistically over a certain period of time. Now has its own Tropes page: Here it is!

Lighting Candles by PitViperofDoom

  • Crossover with: Rise of the Guardians
  • Recommended by: Monoxide
  • Synopsis: The death of Tadashi Hamada was both the end of Hiro's world and the mark of a new beginning. Turns out it was one for Tadashi, too.
  • Status: Complete
  • Comments: This is a really enjoyable fic for both fans of Big Hero 6 and Rise of the Guardians; the characters from each are written well and they interact believably (for example, Jack and Tadashi can't stand each other, to begin with, as Tadashi perceives Jack as irresponsible and Jack considers him uptight). It runs parallel to the Big Hero 6 film, playing with the idea that Tadashi came back as a spirit and later a Guardian after his death (and convinces North to let him protect Hiro as his first Guardian duty), while also having an independent plot and enemy that the Guardians will have to deal with later on.
    • Seconded. Everyone is perfectly in character and the dialogue really reads like a movie script (seriously, give it your best shot with the character's voices). You really feel Tadashi's struggle to adjust and the difficulties that come with suddenly becoming a Guardian. A word of warning, though, Tadashi is very angsty in this fic (justifiably so, but it's there) so if you don't like having your heart strings pulled by heavy doses of depression you're going to want to read this in moderation. That said, the conversations with the Guardians are always funny (Jack's dialogue is dripping with snark) and North is plain hilarious as usual. There is also a fair bit of profanity (crap, damn, hell) that may seem a bit OOC, but rest assured they're not abused too frequently.

Watchers by twelvepercentofaplan

  • Recommended by kilala2tail
  • Crossover with: Guardians of the Galaxy
  • Status: Complete
  • Synopsis: It's all Starch-ahem, Stark's- fault. Quill too, but Stark built the cause of all this trouble. Idiot. Precautions are stupid, and this week turns out to be more or less a getaway on the worst planet in the galaxy. And even better, Rocket's stuck with some kid and a puffy balloon with issues understanding personal space.
  • Comments: "Or: ten interweaving drabbles just barely outlining the events of a week of absolutely nothing but chaos, chip eating, building, and awkward hugging." In which Hiro and Rocket are so similar it's frightening, Groot and Baymax become buddies, and in the end it all works out well.

Empathy and Unity by Finmonster

  • Recommended by: Red-Dead-Redeemer, Eric W, Treguard
  • Crossover with: Home, The Incredibles, Despicable Me and Monsters vs. Aliens
  • Status:
    • Empathy: Complete
    • Unity: Ongoing

Now Riley and her friends have to learn how to deal with these changes, learn to trust their feelings and discover strengths they never knew they had.
    • Unity (Finmonster): Months have passed since the Second Battle of San Fransokyo, and the newly christened Big Hero 9 have settled into the routine of being the city's local superhero. But when a new villain with his eye on not just them, but all the world's superheroes comes knocking, the rookie heroes will have to team up with heroes new and old to take him down. Sequel to Empathy.
  • Comments: By the author of other big crossover fics such as the Mega Crossover universe he created in The Dragon and the Bow. Also, despite the large number of crossovers, most of these are more implied in the backstory or with a Cameo in the dialog. Nonetheless, this gives the universe a sense of depth and mythos that slowly is revealed over the course of the fic. On the other hand, it's also something of a Fusion Fic, combining the end of Inside Out with the middle of Home and Big Hero 6.
  • Pairings: Hiro/Riley, Tadashi/Honey Lemon, Go Go/Wasabi

Big Hero Martian by althor42 Also on AO3 under Anonymous.

  • Recommended by Kalaong
  • Crossover with: The Martian
  • Status: Complete.
  • Synopsis: There would have been no rescue for Mark, if NASA had not noticed he was still alive. Unless of course, a certain Big Hero noticed instead.
  • Comments: A fun, well-researched romp where Mark Watney gets rescued by a Teen Genius instead of an international effort. Notable for exploring the consequences of such an act. Teen Genius builds a spaceship? NASA impounds it. Teen Genius launches said spaceship? North Korea lanches anti-satellite weapons at it. Teen Genius returns to Earth, expecting international acclaim? The Government immediately invokes the Invention Secrecy Act, leaving him with nothing except a NASA draft for his trouble. Maybe he'll get to build another ship in five years. And maybe he'll get to ride in another one in twenty. Hey, he might even get to own one of his ships - in thirty years.
    Dark Fiction 

Stories focused on making the series darker, and/or exploring the darker aspects of the series.

  • Comments: One of the must-reads in Big Hero 6 Fandom and an incredibly well-done alternative take on Tadashi that not only feels in-character but evokes sympathy. Prepare tissues.
