Subverted. While Baymax is round and soft, the jokes about him being fat are not at his expense. They are all focused on the fact that Hiro is trying to force Baymax into a role (and armor) he was never designed to fill; he's a medical robot, not a fighting robot. In fact, Baymax being round and soft is treated as a good thing in the actual movie.
Adaptation Displacement: A particularly severe example. Similar to Guardians of the Galaxy, the comic book remained relatively unknown until it was announced that Disney was doing an adaptation of it. However, Marvel has completely abandoned the original source saying there will be no reprints nor any future stories of the original series. The adaptation is now the definitive interpretation of Big Hero 6.
Callaghan's expression at the end when he's arrested is up as a matter of debate, mainly over whether he feels guilt over his actions as Yokai or disappointment at being sent to prison and separated from the daughter he tried to avenge or possibly both.
With the amount of information given to the audience about the Silent Sparrow project (fairly little) it's impossible to tell if Callaghan was right about Krei cutting corners, or if Abigail was simply the victim of a horrible accident resulting from testing a hazardous new technology, and Callaghan wanted someone to blame.
Callaghan dismisses Tadashi's bravery and willingness to run into the burning building to save him, calling it a "mistake." Was he being a heartless monster so wrapped up in his own pain that he didn't care about anyone else? Or was he reflecting on the fact that his daughter willingly participated in the portal experiment knowing the risks and her bravery resulted in her death — a "mistake" he wishes she didn't make and was mad at Tadashi for doing the same?
Did Callaghan start the fire in the science fair, or did he just take advantage of it to steal the nanobots? They seem to imply he started it, but it's never officially said.
Two aspects from Alistair Krei regarding his villainy:
He tried to walk off with a single micro-bot. Wanting a head start on trying to copy the tech is industrial espionage, but it isn't evil. On the other hand, he had just had an intense but veiled verbal confrontation with Callaghan and it's possible he was rattled by the exchange and legitimately forgot he still had the microbot. Then when it was pointed out to him by Tadashi, his ego prevented him from admitting the mistake in front of Callaghan with a sincere apology.
There are statements relating to the transporter failure. "We've picked up a slight irregularity." "It's well within the parameters." "You knew it wasn't ready." Given that Callaghan obviously thought the machine was ready when he hugged his daughter just before she entered the capsule the balance of evidence indicates that Callaghan was being unreliable here, and that Krei was simply doing his job; which in this case is to proceed given the machine appeared to be within its safety limits. Thus the accident was regrettable but part of the risks associated with testing new, cutting-edge technology.
Is Fred's father really a superhero, or just a zany old man full of hero worship (not unlike his son)? There's no mention of other heroes in the setting, and the man is clearly an — interesting piece of work, as his underpants scene demonstrates. However, it's revealed in the series that he was an actual superhero.
Angst? What Angst?: Unlike Hiro, Aunt Cass takes Tadashi's death surprisingly well, even though she raised him singlehandedly since his childhood.
Ass Pull: Baymax's "death" is particularly frustrating because rewatching the scene in the portal dimension reveals that there was absolutely no window of opportunity for Baymax to have removed his health care chip and slipped it into his rocket glove without Hiro's knowledge..
Honey Lemon. While she has plenty of fans for her energetic, adorable personality and cool superhero outfit, others are turned off by her strong resemblance to Rapunzel, which many perceive as Disney getting lazy with character designs, or because she has "too light" skin (even though that leads into the debate about Hispanic people being widely varied in appearance).
Professor Callaghan has his share of fans but there are others who think that he's not a good villain. Not only his reveal as Yokai was so obvious to the point that many people easily saw Krei as the designated Red Herring (to the point that Disney used him as the antagonist in their advertisement), but telling Hiro than Tadashi's death was "his mistake" has most of the audience seeing him less as a tragic villain and more as a one-dimentional villain whose only redeeming trait was his sympathetic backstory.
Broken Base: Some critical fans see the return of Abigail and Baymax as a detriment to the films message of loss. Others, however, have made the point that Abigail being alive perfectly matches the point about how death and loss affects people. This is a notable distinction since her survival doesn't change how the Big Bad chose to handle their grief on the belief that they're dead. The message of loss isn't really lost because of this. Baymax's return is a bit more contentious to some even then, especially in light of how it's handled, though others feel that it also fits just fine as is.
Captain Obvious Reveal: Krei is such an obvious choice for Yokai's true identity that the movie wouldn't even try to make it a twist if it was true. Subverted in that although many of them suspected it was Tadashi rather than Callaghan, Tadashi stayed dead.
Cargo Ship: Many shipped Baymax with soccer balls as soon as the first trailer was released.
Cliché Storm: General consensus is that it's a good story backed by some nice visuals, but pretty by the books when it comes to superhero films with many tropes done beforehand.
Tadashi and Elsa from Frozen for having that common thread that these two are the very popular older siblings that have even came close to overshadowing their respective younger siblings where they are the real main characters!
Ever since Coco was released, fans have taken a liking to pairing Hiro with it's protagonist Miguel.
Cause we could be immortals, immortals Just not for long, for long And if we meet forever now, pull the blackout curtains down Just not for long, for long We could be immortals, immortals, immortals, immortals
Since Honey and GoGo are only known by their nicknames, fans have speculated that their respective real names are Aiko Miyazaki and Leiko Tanaka, much like their comic counterparts. This is highly unlikely due to their Race Lift to Latina and Korean, and in GoGo's case, it was Jossed when Jamie Chung stated on Twitter that her first name was Ethel.
Much of the fanfiction and fanart out there depicts Tadashi as being alive with severe burn scars, but not much more, likely due to his Ensemble Dark Horse status. It's become a joke within the members of the fandom that the movie's canon must have been false. Tadashi's obviously just in some hospital healing, and will definitely be back in the sequel, if there is one. Alternatively or additionally, he'll return as Sunfire.
Honey Lemon being a Disney princess, or even being descended from Rapunzel (which would make her a Disney princess by lineage anyways).
In addition to the green (healthcare) and red (attack mode) chips, there's a blue and a yellow one on Hiro's table. Makes you wonder what they would be used for (and the same scene shows Baymax has enough slots for all four!)
Hiro is frequently portrayed as claustrophobic, often having this revealed by jerks at the university shoving him in a locker and being discovered by one of the team. If any explanation is given for the phobia, it's usually because Hiro was stuffed in lockers during his high school days or, rarely, because he was in the car when his parents died and got trapped in his car seat.
Due to the manga adaptation and Hamadas' nationality it's fairly common to find stories where the two speak to each other almost entirely in Japanese or use Japanese words intermingled with English, despite the fact that neither of them did so at all in the movie.
Fred's full name is Frederick Lee - because his dad is Stan Lee.
Many fans like to think that, like her nephews, Aunt Cass' last name is Hamada note This is despite the fact that Cass is Caucasian, as well as a Freeze-Frame Bonus revealing that Hiro and Tadashi's father was Japanese while their mother (who Cass does bare a resemblance towards) was Caucasian, which implies that Cass is their maternal aunt. So unless she also married into the Hamada family like her sister, her last name being Hamada is unlikely.
When Hiro and Baymax are in the half-portal realm trying to save Abigail, you may see a beautiful landscape in the background constantly changing. This is a Mandelbulb set, a three-dimensional analogue to the Mandelbrot set.
Yokai's kabuki mask has red streaks on it. In kabuki theater, red symbolizes passion, alongside anger and cruelty. This makes much more sense after Yokai is revealed to be Callaghan, whose crimes are driven by passion for revenge, in anger over his daughter's death. White, the main color of his mask, is almost exclusively reserved for evil characters and villians due to its association with death in Japanese culture.
He's Just Hiding!: It's become a fandom Running Gag to pretend that Tadashi survived the fire somehow. Not surprising, considering the other victim of the fire turned out to be just fine. And the real villian.
Ryan Potter just does an outstanding job in displaying his emotions as Hiro, especially when Baymax talks him out on his revenge against Callaghan and when Baymax is forced to pull a Heroic Sacrifice.
Who knew that James Cromwell can do remarkably voicing the Big Bad? The fact that his character eventually turns out to be a Tragic Villain also proves that Cromwell did spectacularly in displaying the character's emotions.
In Iron Man 3, Tony Stark reveals he still had a nanny when he was fourteen years old. Given that a nurse bot is a futuristic nanny, that pretty much describes Hiro.
Season 2 of Avengers, Assemble! introduces Arsenal, a robot whose primary function was to serve as a companion and eventually goes on to heroically sacrifice himself, only to get rebuilt by the lead protagonist. Doesn't that sound a lot like Baymax?
In the episode "The Age of Tony Stark", a de-aged Tony looks a lot like Hiro.
Stan Lee's cameo as a retired superhero is this, when you remember that in the The Amazing Spider Man video game, he's a playable character and his gameplay is the same as Spider-Man.
Not exactlythe first time a girl supposedly died in another dimension, resulting in her loved one turning evil and beginning a quest to avenge/retrieve her, even if it means throwing away his morals and hurting countless innocent lives. Well, at least not to the extent of threatening Armageddon...
There are actually people who think that it was the right thing for Hiro to try to kill Callaghan.
On the flip side, some people are giving Callaghan too much sympathy. They seem to be forgetting the fact that Callaghan was callous towards Tadashi's death and attempted to murder his students.
Narrowed It Down to the Guy I Recognize: Let's be honest: did you REALLY think Disney was going to hire James Cromwell to voice a character for less than a dozen lines of dialogue, then kill him off in the prologue?
Ron the Death Eater: A strange variation with Tadashi. While he's rarely an outright villain in fanfic, his protectiveness of Hiro is often twisted into a disturbing and sometimes even violent Yandere-like obsession, especially in darker Hidashi fics.
Shipping: Running rampant due to no canon couples. Hiro and Honey are particularly popular in this field.
Wearing your underwear forwards and backwards and inside out just moves the sweaty, yucky bits around.
Where does GoGo get so much gum? She doesn't. The junior novelization implies that she keeps chewing the same gum for days to weeks on end, and that being on the dashboard of a car and having floated up from the San Fransokyo bay will not stop her from putting it back into her mouth.
In the original Marvel comics the movie is inspired by, the team was based in Tokyo and everyone was Japanese. Disney's decision to change most of the characters' races is the biggest point of controversy (only their superhero names are still the same), and there's also the setting being moved from Tokyo to the entirely fictional hybrid city San Fransokyo.
While most characters being changed from superpowered to just relying on technology seems to have been overall accepted, most fans of the comic didn't particularly like Fred being changed from actually turning into a Kaiju to just wearing a monster suit.
Tough Act to Follow: While the movie itself was far from a failure, it does tend to get overlooked because it was released in between the cultural juggernaut Frozen and the enormously popular Zootopia, both of which made over a billion dollars at the box office. It also leads into the problem of optics: Frozen and Zootopia were sleeper hits that weren't expected to make anywhere near as much money as they did, while Big Hero 6 was a superhero movie made during a golden age of superhero movie profitability, so while its $657 million gross does make it one of the biggest movies ever for Disney Animation, it also made it the lowest-grossing major superhero film of 2014.
They Wasted a Perfectly Good Character: Hiro and Baymax's teammates didn't really get much development and had rather one-note personalities, but the film would probably go in a very different direction without their inclusion, especially since they were able to stop Baymax from killing Yokai.
Hiro was holding the kabuki mask when he got angry at Callaghan. It would have been interesting to see what would have happened if he put it on.
The illegal bot fighting rings taking place in San Fransokyo. Only one scene is dedicated to it, and that was the beginning of the movie, and was never mentioned again. It ended up getting revisited in Big Hero 6: The Series, though.
Too Cool to Live: Tadashi was a good older brother, a noble worker, and intelligent student. Which in Disney terms, means he's a goner.
Too Dumb to Live: Tadashi raced back into a blazing building to rescue Callaghan. It's good to have the mindset that somebody should do something but... it's really tough to balance out bravery and stupidity. You should never re-enter a burning building and Tadashi should have known that.
Tough Act to Follow: This is the film that had to follow up on Frozen. If you look at the raw numbers and critical response — it did admirably; even outperforming it in some circles. Thing is, the sheer runaway success of Frozen meant that at the end of the day, it was still getting a huge push even during Big Hero 6's run; look at any Disney Store today and it's easy to notice that while Frozen still has a coveted spot on the racks (even as other characters and films rotate out) — Big Hero 6 has all but disappeared.
Unintentionally Sympathetic: Hiro trying to kill Yokai/Callaghan in Revenge for Tadashi's death is treated as a near-Moral Event HorizonIn-Universe. However, some fans actually support Hiro on this, given (1) Yokai/Callaghan's rather unfortunate implications and (2) Hiro — unlike Yokai/Callaghan — attacked only a deserving target instead of innocent bystanders as well.
Unintentionally Unsympathetic: Yokai/Professor Callaghan can come across as this to some viewers because even though he was wracked with grief over his daughter's death, he still attacked students in ways that could have caused their deaths, stole government property, gave a No Sympathy response to Tadashi's sacrifice and destroyed KreiTech headquarters with the intention of destroying Krei himself with absolutely zero concern for the Innocent Bystanders that would be around.
Viewer Gender Confusion: Mochi, the Hamada cat has a calico fur pattern, but is confirmed to be male, even though his gender is never outright mentioned once in the film. Calico cats are nearly always female due the calico gene being found on the X chromosome. However, it is possible for male cats to be born calico, though they are exceptionally rare. About 1 out of every 3000 cats is a male calico.
What an Idiot!: Tadashi charging into the burning building can easily invoke this reaction, since he's charging into a fire to save a man that he has no idea where he is, and on top of that has no training or equipment to help him. He's a first-responder's nightmare because he's at best creating another person to try to save. And if there hadn't almost immediately been an explosion, Hiro very likely would have followed him in as well. He's smart, but damn was that dumb.
The Woobie: Hiro, especially in any scenes relating to Tadashi's death, as well as when he loses Baymax.
