YMMV / Big Hero 6: The Series

• Abandon Shipping:
  • When Trina was introduced in "The Bot-Fighter", fans saw her as an alternate pairing for Hiro as she helped him with the underground bot fights and even kissed him after one. Not even the revelation that she was a robot and Obake's creation was enough to deter them. Only after her breakdown and full descent into villainy did fans of her finally back off.
  • Fans hopped off the Chris/Wasabi ship after Chris was revealed to be just as evil as Liv/Di. Even in the Alternative Character Interpretation of Chris' actions are related to his boss implanting ideas into his mind, fans felt like any possible crush Wasabi may have had on Chris was treated poorly and didn't head anywhere in the end (since Chris and Liv ended up being Put on a Bus at the end of the "City of Monsters" arc).
• Adorkable:
  • Obake used to have a prominent dorky side in his youth, as shown in the flashback from "Mini-Max" where he excitedly grinned at Professor Granville to show her his work. Even if he grew up to become a much more cold and sinister individual, he kept a part of his past excitable streak, like in the scene where he tells Hiro he cannot wait for him to become his apprentice and create things together.
  • Despite being a villain, Globby's clumsy tendencies and him giddily learning to control his powers make him this. After his Heel–Face Turn, Globby's dorkiness is emphasized when he's excited to be part of the good guys and help Big Hero 6 save the city.
  • Underneath her grumpiness and aloof demeanor, Karmi hides a huge dorky side. Best proven whenever she gets excited by something biotech or Big Hero 6 related (especially in regards to her beloved "Captain Cutie".) She also loves cute stickers and puts them on her virus' containers. That side of her warms her up to Honey Lemon, and eventually Hiro.
  • Megan's very excited about being a journalist and trying to discover Big Hero 6's real identities. She also calls herself "Super Sleuth Megan Cruz".
  • Supersonic Stu. He's dimwitted and childish, which added to his innocence and cheerfulness makes him a lovable sweetheart.
  • Hardlight sees his world as a video game, and he can be shown being genuinely geeked out about fighting superheroes.
  • High Voltage are dangerous criminals, yes, but they're quite endearing and excitable, mostly Juniper. The top of which is "Something's Fishy" when they try to be normal civilians. That's one of the reasons they're one of Big Hero 6's friendliest foes.
  • 4 2 Sing's eagerness to be superheroes comes across as such.
• Alternative Character Interpretation:
  • Krei is a lot meaner in the series than in the movie. Was he always like this, or did the events of the movie leave him feeling invincible? For the former, the movie always had him talking in public, so he had to be polite. On the other hand, he openly insulted Globby and dared to blackmail Big Hero 6, both of which could've risked his safety. Either is still possible.
  • Obake gets a lot of this.
    • The Season 1 finale reveals that he suffers from a brain injury that makes him unable to tell right from wrong as a result of an experiment gone wrong. The revelation throws into question how much of Obake's actions are of his own will. Was he an unfortunate victim of circumstances where his accident was his Start of Darkness? Or was Obake already a science-obsessed maniac from a young age, and the accident was merely a catalyst that allowed him to cut loose? Obake seems fully aware of his condition but refuses to have it treated since he actually enjoys the freedom from a moral compass.
    • When Obake decides to seal his fate in his collapsing lair and refuses Baymax's aid, he takes off his chip from Baymax's system and pushes him to go save Hiro. Despite his inability to recognize right from wrong and his pleasure in villainy, Obake died doing the right thing. Did he regain some morals before dying? At the same time, his mercy towards Hiro, whose potential he acknowledges, can be seen as consistent with his belief that scientific progress trumps all, making his good deed appear to be a case of Moral Sociopathy.
  • Is Chris as evil as his boss on his own will? Or is he only evil because he's her Human Pet and she implanted her lack of morality into him, and he doesn't know better than what he has from his programming?
• Anti-Climax Boss:
  • Trina in the Season 2 finale, whose plan to destroy the city is not as difficult to stop as Obake's was in the Season 1 finale, and who goes down in combat ridiculously easily.
  • In the same finale, Chief Cruz, who has been obsessed with bringing down Big Hero 6 for the entire season, changes his entire worldview and gives up on antagonizing them after they save his daughter. Given that he blamed a superhero for a villain placing his father in danger, it's odd that he didn't blame Big Hero 6 for Megan's predicament, as it could be argued that it happened because of them. The only difference between what happened to his father (which sparked his anti-superhero crusade) and what happened to his daughter (which ended it) is that his daughter survived.^note It could be argued that this was because Megan's life was threatened by the Buddy Guardians, who were commissioned by Chief Cruz on his crusade against superheroes. He may have blamed himself for going too far and bringing in the Buddy Guardians who could have very well killed Megan, and he was grateful to BH 6 for saving her.
• Awesome Art: The movie's CGI translates very well to 2D, keeping the same style while adding in some nice comic book-style animation. It helps that the Creative Closing Credits of the movie already gave the series a template to work with.
• Awesome Music:
  • The theme song helps capture the action sci-fi tone of the series.
  • The background songs that play when High Voltage is on screen are catchy. And then there's Barb's Villain Song from "Something's Fishy". While Big Hero 6 is far from a musical comedy like Tangled: The Series, Barb completely nailed that song.
  • "When Your Name Is Globby" from the episode "Nega-Globby" as Globby fights his Evil Counterpart and Honey Lemon defeats it with her upgraded chem-purse. Awesome song for an awesome scene.
  • "No Substitute for You" from the episode "Fear Not" is very sweet and heartwarming.
  • "Krei-oke Night" is full of this.
• Base-Breaking Character:
  • Karmi. Fans either hate her for being a Bitch in Sheep's Clothing and being overly harsh to Hiro and Baymax to an extent with little provocation while being obsessively in love with Hiro's superhero alter-ego (not to mention making it unlikely for the comic book character, Marys Iosama, to appear), or fans love her for her Friendless Background and potential for Character Development, not to mention frequent moments where she is funny (the absolute peak of which being the episode "Fan Friction"). It probably doesn't help that she knew about Tadashi, whose death was very recent, and still bullied Hiro. Seems to have become less contentious in Season 2, where her Character Development has so far made her more amiable to Hiro and co., and the high stakes around her have made fans worried for her well-being. Look at Author's Saving Throw and Rescued from the Scrappy Heap.
  • Richardson Mole, Fred's comic book rival, is either too smug and annoying or funny in an "I don't care what others think of me" kind of way. The episode "Big Hero 7", which is also divisive, didn't help matters. "Mayor for the Day" makes him even pettier, giving him Syndrome vibes.
  • Each member of the titular team is a base-breaking character in their way.
    • Hiro and Baymax are the most notable offenders. Some fans appreciate their relationship and quirks, while others are tired of them always taking the spotlight for the majority of the series's episodes while their teammates are relegated to the sidelines. They felt that it was time for the teammates to shine, given that the movie had already delved into the two's relationship enough. Even when Season 3 has segments that don't include every team member, Hiro, and Baymax continue to appear in every one, never being absent to give the spotlight exclusively to the rest of the team.
    • Wasabi and Fred both fall into this for one reason. Their hidden depths are downplayed in favor of making them a bigger source of comic relief than the movie, with one side being very annoyed with them and the other side arguing they still get plenty of time to shine.
    • Downplayed with Honey Lemon, but her more exaggerated perkiness either makes her annoying or she's still an engaging character.
    • One complaint some people have with GoGo is how she seems to go through character regression with her still softer moments being downplayed in favor of upping her tough side. With that said, she still has fans who appreciate it when she's kinder.
  • Noodle Burger Boy is also one. Due to being a crew favorite, some fans who find him annoying didn't approve of him becoming the new Big Bad of Season 3, while others who have loved him since Season 1 are excited to see where this new route will lead the character.
• Broken Base:
  • In a similar vein to the movie, the show having almost no basis in the comics it's based on, and not making any connections to Marvel characters, is either a good choice to let the show stand on its own or feel that the potential could be better utilized with a Shared Universe.
  • The more overt and over-the-top humor is either funny or annoying.
  • The art style is also up for debate. One side thinks it looks like Flash garbage (even though this is hand-drawn) and it's too simple and stiff. The other side doesn't mind it and thinks it looks great, being reminiscent of the comic books it's based on. Those in favor of the latter point to The Spectacular Spider-Man, which has a simple, yet bold art style, and feel that the simpler art style here is to help make the action scenes more enjoyable to watch, like here.
  • Unlike most other action shows that utilize a core team, the titular team appears together in every episode. One side argues that there should be episodes that don't have all of the team together to enhance the quality of the more character-specific episodes, while another side argues that there are still plenty of episodes that give other characters time to shine even with the team together in every episode. Season 3 attempts to fix this by having only a few members of the team make appearances in episodes, but given the controversial shift to a comedic focus, whether it works or not is up to the viewer.
  • While not to the same extent as Tangled: The Series, the Cerebus Syndrome is a bit controversial. Put simply, the back-and-forth switch between the wackiness and drama either makes for a huge case of Mood Whiplash or helps keep the show from going to either extreme.
• Catharsis Factor: Mr. Cruz disregarded good actions of Big Hero 6 in the past and tries to arrest them at all costs throughout the second half of season 2, even going as far as to stage a crime to lure them in. It's really satisfying when he realizes his actions lead to Trina capturing his daughter and begs Big Hero 6 to help him.
• Creepy Cute: Noodle Burger Boy, and the other mascots from Season 3.
• Cry for the Devil: Obake may be a Mad Scientist who's willing to kill millions For Science!, but you can't help but feel bad for him when it's revealed that he's suffering from a brain injury that makes him unable to differentiate right from wrong. You'll definitely feel sorry for him when his plan is thwarted and he suffers a Villainous BSoD that causes him to be Driven to Suicide.
• Designated Villain: Both Ned Ludd and Mel Meyer are not actual supervillains. They are both quite nice and good people, but both of their goals have a dangerous motive that puts them against Big Hero 6:
  • Ned Ludd is a technophobe hermit who due to losing his sanity over the years spent alone in the woods, saw Baymax as a threat to humanity and thought was doing the right thing by attempting to push him off a cliff. (thankfully, Character Development helps him in future episodes).
  • Mel Meyer is a good-hearted scientist who wanted his flexible display technology to be used for good things, not to attack people as Krei used said technology to create the Buddy Guards. Considering there was no way Mel could make a deal with Krei by asking nicely, who can blame him for trying to steal it back? Even Aunt Cass admits Mel had a reasonable motive.
• Ensemble Dark Horse:
  • Professor Granville, for being a Reasonable Authority Figure and Cool Teacher who wants the best for her students.
  • Trina, as she has the same voice actress as Kim Possible.
  • Megan for being a Nice Girl with a cool character design and getting along very well with Hiro. Her keeping the identity of Big Hero 6 a secret helps out.
  • Mini-Max as well, due to being a fun-loving little guy just like his big buddy Baymax.
  • Globby, due to his likable personality, a unique application of his abilities, and eventual redemption.
  • The instant Hardlight was introduced, he immediately got a positive response from fans due to being simultaneously a tough opponent, and an adorkable nerd with hilarious sarcastic quips. And he's not ugly.
  • While Momakase wasn't unpopular to start with, her fanbase grows even bigger after her past and Pet the Dog moments in "Hiro The Villain".
• Evil Is Cool:
  • Obake, a bombastic Evil Genius and Chessmaster who stays one step ahead of the heroes, and is voiced by Jim Moriarty.
  • High Voltage is the first female villains to be introduced and has immediately received positive reception with their comical gimmicks and dance moves (including their soundtrack).
  • Momakase is a skilled and badass Ninja who can knock out an entire bunch of mooks like it's no biggie.
  • Then there's Hardlight, who treats real life similar to a video game.
• Fan Nickname:
  • "Scone Daddy" or "Glowstick Man" for Obake.
    • The robotic copy of him that appeared in "Countdown To Catastrophe" is called "Robake".
    • His younger self is sometimes called "Emobake" due to Obake having an Emo Teen haircut.
  • "NBB" for Noodle Burger Boy.
  • Momakase is referred to as "Knife Wife" or "Knife Mom" by her fans.
• Fanon: It's popular to portray other cities and places in the world of the series as also being mash-ups of two different locations, such as Karmi coming from "Pakistindia". In the actual canon of the series, San Fransokyo is the only such location, but fanfics still extend it to other locales, because hey, it's fun (Which is also what the original writers were thinking when they made San Fransokyo, too). Has become Ascended Fanon with the character Sirque, who hails from Leontreal, and a mention of Austanbul in Season 3 Episode 1.
• Foe Yay Shipping:
  • Some fans ship Hiro and Trina, despite the latter being a psychopathic Robot Girl, interpreting Hiro as a Robosexual.
  • Some fans interpret Momakase and Aunt Cass' rivalry in "Food Fight" as Belligerent Sexual Tension and a case of Dating Catwoman.
  • After "Cobra and Mongoose", fans started to ship the titular villain with Heathcliff, as their passive-aggressive banter was very much so similar to flirting and made the pair another example of Dating Catwoman.
• Growing the Beard: The pilot movie retreads a lot of ground (due to being an extended version of the film's epilogue), and the first five episodes of the series proper are rather by the numbers. "Failure Mode" is the point where the series starts putting greater emphasis on the Myth Arc and also becomes more creative with how the heroes and villains outsmart each other.
• Harsher in Hindsight:
  • In "Food Fight", Aunt Cass thinks Hiro is bot fighting again. Hiro does go back to bot fighting in "The Bot Fighter".
  • In "Issue 188", Wasabi jokes to Hiro to tell Karmi he has a clone so she doesn't doubt he's the superhero she's crushing on, to which Hiro replies Karmi will see through it. Then comes Season 2 where the Big Bad is an evil clone, and Karmi never doubted for a second of Liv/Di's true colors.
  • In "The Hyper-Potamus Pizza-Party-Torium", Hiro being saddened over his friends potentially finding jobs in another city hits harder when you remember that people he cared about have always abruptly lived his life before; either they died (his parents and Tadashi), or they had to move out (Karmi), and there was nothing Hiro could do to stop it.
• Heartwarming in Hindsight: Stan Lee's final time portraying Boss Awesome happened to be the one episode where Boss Awesome suits up one last time to help BH6 apprehend his villains personally. Though Mr. Frederickson is confirmed to avert The Character Died with Him, it's heartwarming to know Stan went out as a hero.
• He Really Can Act: Andrew Scott is often known for playing slimy and despicable villains. However, fans were surprised by what an immensely heartbreaking performance he made in Obake's final moments.
• He's Just Hiding:
  • How fans deal with Obake's supposed death. Helps that his fate is vague and they Never Found the Body.
  • Just like with the movie, some fans are still convinced that Tadashi isn't dead, theorizing he might be revived or cloned by the Big Bads.
• Hilarious in Hindsight:
  • One article released before the film compared Wasabi to Cyborg from Teen Titans (2003). Jump three years later to this series, and he's voiced by Khary Payton, the voice of Cyborg.
  • Hiro's voice actor, Ryan Potter, is also playing Beast Boy in a live-action series about the Titans, though ironically this version of the team does not feature Cyborg.^note Due to the character becoming more associated with the Justice League (2017) film set in the DC Extended Universe.
  • One of the villains in the series is High Voltage, a pair of villains that attack with electricity by dancing. Sounds like they got inspiration from Electric Boogaloo.
  • The creators of the show are the same creators of Kim Possible, which had a crossover with Lilo & Stitch in its own series, and Lilo & Stitch has one of the most well-known cameos in the film.
  • While on that note, Mole's voice actor, Sean Giambrone, would be cast by the creators in the live-action Kim Possible movie as deuteragonist Ron Stoppable.
  • In "Baymax Returns", Honey Lemon tells Fred that she's not comfortable with having frozen someone. Later, in "Big Roommates" she doesn't seem to be as concerned when she accidentally freezes her roommate.
    • Even funnier when in "Hardlight", she freezes police officers on purpose this time so they don't arrest the team. Though she does apologize to them due to how she is.
  • In "Baymax Returns", GoGo shoots down Fred's enthusiasm for getting the team back together by telling him superheroes and villains don't exist, but then in "Fred's Bro-Tillion", she learns Fred's dad was a superhero with many enemies.
  • A theory in the Kim Possible fanbase was that Kim was a robot built by her father, who is a rocket scientist. Big Hero 6: The Series is created by the creators of Kim Possible and Kim shares her voice actress with Trina, who turns out to be Obake's robot "daughter" who he built.
  • Not the first time Jane Lynch portrays a boisterous sarcastic woman named Sue.
• Ho Yay:
  • Fred came up with names of ships in the team, including "Fredsabi", and says he thinks Wasabi will be a fan favorite because "he's so cool".
  • Chris, Liv Amara's assistant in Season 2, seems to be quite interested in Wasabi.
  • Globby's relationship with Felony Carl in Season 2. Globby's realization that Felony Carl is his Only Friend at the end of Season 1 was accompanied by the line "If anything thing happens to me, tell Felony Carl he was my whole list," which is a slightly different context would be the closest the show has come to a Love Confession from anyone. The bar is raised even higher in the first half of the series finale, "Krei-oke Night" when they perform a love duet.
• I Knew It!:
  • After "Big Problem" aired, many fans correctly guessed that it was set-up for Season 2's story arc and that Liv Amara would be the new Big Bad.
  • That Chris is not human due to his Undying Loyalty to Amara and his strange behavior.
  • That Karmi would be mutated into a monster by Amara towards the end of Amara's arc.
  • Many fans who saw the final picture in Season 2's penultimate episode correctly guessed the person shown was not Obake, but rather Trina, primarily due to earlier foreshadowing and the shadowed figure's head not being as long as Obake's.
• Jerks Are Worse Than Villains:
  • Richardson Mole is a Spoiled Brat who does everything he can to make Fred's life a misery, and constantly flirts with Gogo (to her disgust). The team as a whole finds him more repugnant than the supervillains they regularly face.
  • Chief Cruz tends to be hated more than the regular rotation of supervillains due to his Jerkass behavior, obstructive belief in the Superhero Paradox, ungrateful behavior when Big Hero 6 helps him, and his motivation not justifying his crusade. He tellingly isn't featured at all in the final season.
• Launcher of a Thousand Ships: Hiro is shipped with pretty much every girl in his age range, such as Karmi ^note they have a mutual passion for science even though she's a Base-Breaking Character, Trina ^note they have a mutual passion for robotics though given that she's Obake's robot daughter, it's pretty much sunk, but it hasn't stopped anyone, and Megan ^note she's the nicest of the three but has a police chief father who hates superheroes.
  • Wasabi qualifies as well; he's paired with Gogo, Fred, Honey Lemon, Tadashi, and Chris. He's even paired with half of 4 2 Sing!
• Les Yay:
  • The series, mostly the "Big Roommates 2" and "The Fate of the Roommates" episodes, give us plenty of Honey Lemon/GoGo content.
    • In "Fate of the Roommates", Honey prepares to move out of GoGo's apartment, which would mean that the girls stop living together but would still see each other a lot in the SFIT and their superhero life while just hanging out. Yet, GoGo is upset as if they were breaking up, and other characters comment on it. She needs quite some effort and time to work up her courage and ask Honey to stay. Honey gladly agrees, and the girls share a tender hug.
    • In "Hiro The Villain", Honey says she'll go on patrol with GoGo with such delight, almost like they are going on a date.
    • When villains throw things at the team, GoGo usually grabs Honey and carries her away from danger. Bridal-style.
    • In "Krei-oke Night", Gogo is indifferent to pretty much all the songs, except Honey's.
  • Another one with GoGo, but the third issue of the comics has a Ship Tease conversation between her and the Villain of the Week Mechadama/Olivia Vega.
• Love to Hate: Both Big Bads, Obake and Liv/Di. Although both commit horrible actions during their reign as the main antagonist of their respective seasons, fans can't bring themselves to hate them, finding them extremely good-written villains. Although it goes up a notch for Liv, as contrary to her, Obake showed himself to be extremely vulnerable in his final moments and a case of Tragic Villain. Liv, for herself, is a sociopathic Manipulative Bitch who commits horrendous actions For the Evulz. Some fans state that as much as they love Liv as a villain, they can't bring themselves to ever forgive her for manipulating and mutating poor Karmi and causing her departure from the second half of the season.
• Magnificent Bastard: Obake, real name Bob Aken, was once the top student of Professor Granville. After an unsupervised lab experiment ended in disaster, Obake was left with a brain tumor that left him incapable of differentiating right from wrong. Fascinated by artist/scientist Lenore Shimamoto's work, Obake flawlessly manipulates both heroes and villains alike into acquiring Shimamoto's research as well the secret identities of Big Hero 6, taking a close interest in Hiro Hamada. He secretly observes and gauges the boy's growth from the shadows, even going so far as disguising himself as Hiro's dead brother. In the season finale, Obake reveals his grand plan to recreate Shimamoto's failed experiment that caused the Great Catastrophe, and rebuild San Fransokyo into something "perfect". He takes control over Baymax and captures Hiro in hopes of swaying him into becoming his protégé once the dust settles. Thwarted by the heroes, a heartbroken Obake lets himself go down with his collapsing lair, but not without freeing Baymax from his control to go back to Hiro and save the boy who he deemed his equal. A Visionary Villain whose charming brilliance is rivaled by his ruthlessness, Obake is established as Big Hero 6's most diabolical foe to date.
• Misaimed Fandom: Once again, some fans say that Tadashi should return and be more focused on in the series (ex. he should have been The Sixth Ranger in "Big Hero 7" as opposed to Richardson) even though the Aesop of the story is to keep your loved ones in your thoughts while you move on with your life, with the series continuing that lesson by showing the characters moving on with their lives.
• Moe: The show uses this quite effectively:
  • Hiro is still this as in the movie, where he can be quite a adorkable nerd and occasionally socially awkward when talking to girls.
  • Honey Lemon is also this with how sweet, cheerful and dorky she is.
  • Karmi falls into this when she acts like an adorkable nerd excited about science and a bubbly (and relatable) fangirl.
  • Megan with her cute design and excitable streak when it comes to journalism.
  • Professor Granville eventually becomes this when she loosens up when showing her Genki Girl tendencies and a hidden dorky side.
• Moral Event Horizon:
  • Fans felt that Obake crossed it when he tricked Hiro into thinking that his dead brother was alive. This is even treated as one in-universe by GoGo and Wasabi, thinking that Obake crossed the line this time.
  • It gets much worse in the season finale, where he plans on recreating the Great Catastrophe to make an artificial star, despite knowing full well it will destroy San Fransokyo and kill millions of innocents.
  • Liv Amara's clone Diane crossed it in "City of Monsters" when she forcibly turned her 16-year-old intern Karmi who idolized her into a monster and kidnapped Hiro and Baymax to force them to cure the real Liv Amara. When they succeed, she tries to mutate Hiro and then force the monster Karmi to kill him since He Knows Too Much.
• Narm: Big Hero 6 has secret identities despite their costumes clearly showing that they're the same person (except for perhaps Fred^note Who still seems to take every opportunity to pop his head out of his costume, with little regard to who's present to witness it) and numerous characters already knowing who they are in the film. However, this is something carried over from the end credits of the film, as it was kept vague as to whether or not the media knew that Big Hero 6 were college students. Possibly a case of Status Quo Is God in case the movie gets a sequel that wants to address this.
  • Lampshaded in a big way in "Issue 188", when Hiro can't believe that fellow Teen Genius Karmi can't tell that Civilian!Hiro and Hero!Hiro are the same person, despite having seen both up close.
  • Comes back in "Countdown to Catastrophe" when each member of the gang gets a Dramatic Unmask after Professor Granville reveals that she knows full well that they're Big Hero 6. Later on, Megan figures out Hiro's identity by connecting the dots from the SFIT fire, and matches Hiro's face out of costume to his face in costume.
• Narm Charm: Karmi's fan names for the individual members of Big Hero 6. Some of them are genuinely cool, like Flamejumper for Fred, Speed Queen for GoGo, Red Panda for Baymax, and Chop-Chop for Wasabi, and then you have the low-effort Tall Girl for Honey Lemon and Captain Cutie for Hiro.
• Never Live It Down: Obake was seen one time eating a blueberry scone. Because of this, the fandom on Tumblr constantly makes jokes about Obake having a scone addiction (who borderlines on a kink) and now nickname him "Scone Daddy".
• No Yay: Obake's fixation on Hiro is very disturbing when you realize how Obake is obsessively stalking Hiro, such as observing his everyday life to create a Robot Girl that flirts with him. There's also the fact that Obake is an adult in his 30s and Hiro is fourteen.
• Portmanteau Couple Name: It's lampshaded more than once in "Fan Friction". Karmi calls her pairing with "Captain Cutie" "Karmutie". Fred, gives a bunch of ship names among the gang, like "Gogosabi", "Fredsabi" and Honeysabi. He also asks Momakase if her ship name with Obake is called "Momobake" or "Obakase". Though in the actual fandom, there's quite a chunk of these:
  • Karmi/Hiro = Karmiro
  • Megan/Hiro = Megiro
  • Trina/Hiro = Hirina
  • Karmi/Megan = Karmegan
  • Karmi/Juniper = Karmiper
  • Honey/GoGo = Honeygogo
  • Chris/Wasabi = Chrisabi
  • Cass/Obake = Obacass
  • Cass/Momakase = Momacass
  • Felony Carl/Globby = Felonyglob
  • Cobra/Heathcliff = Cobracliff
• Rescued from the Scrappy Heap: Karmi. She was a character with mixed responses in the first season due to her harsh behavior towards Hiro and Baymax. But as Season 2 goes on, Character Development hits her, and considering she's in the middle of the Sycorax mess unbeknownst to her, fans now worry for her safety. This worry is justified when Liv gives Karmi an "upgrade" against her will in City of Monsters. After being Put on a Bus, people who previously hated her now appreciate her Character Development and hopes she comes back. They also appreciate her cameo in "Legacies" and were delighted by her return in "Big Chibi 6", which some consider one of the best episodes of the new 11-minute format.
• The Scrappy: Chief Cruz for being the stereotype of the law enforcer who hates superheroes, even though Big Hero 6 had saved the city countless times. Even when the news mentions that crime has gone down to an all-time low thanks to the team in the first episode of Season 2, his illogical deduction that superheroes attract supervillains makes his hatred of superheroes seem to be out of nothing but spite. The hate towards him grew when he shrugs off Big Hero 6 saving his life and still wants them arrested. Not only that, but his annoying Boyfriend-Blocking Dad tendencies toward Hiro for getting close to his daughter come off as hypocritical considering that he tries to date, Aunt Cass. Even after his backstory has been revealed, it made fans dislike him even more as his backstory is cliché and makes his hatred of superheroes selfish and mostly motivated by pride. While Megan Cruz is at least mentioned in Season 3, her father never makes any major appearances, quite possibly due to this tepid reaction.
• Seasonal Rot: Some would say the show fell into this after the "City Of Monsters" two-parter in Season 2, mainly due to the unengaging arc involving the team becoming fugitives, the team (excluding Hiro and Baymax) having rather minimal Character Development, plot lines involving characters like Trina that had potential but were executed poorly, and (thanks to Executive Meddling) Season 3 having a shortened season and placing more emphasis on comedy over storytelling and Character Development.
• Ships That Pass in the Night:
  • Cass/Krei (though sunk)
  • Cass/Obake is surprisingly popular, despite them interacting only once, in "Kentucky Kaiju".
  • Juniper and Karmi haven't met yet, but there's already a ship name and fan content for them.
  • Also Karmi/Megan, who did not meet since Karmi gets Put on a Bus at the end of the City of Monsters arc and only reappears for one episode in Season 3 and Megan does not appear at all in Season 3.
  • Some fans ship Juniper and Megan, who maybe did not interact, but appeared in the same episode, and High Voltage (indirectly) ruined the dance night at Megan's school.
• Ship-to-Ship Combat: Especially after "Big Chibi 6", fans are divided over whether Hiro should end up with Karmi, who now has feelings for Hiro (his real self, not "Captain Cutie"), or Megan.
• Squick:
  • In "The Bot Fighter", Hiro falls for a girl named Trina, who seems to flirt with him, even kissing him on the cheek. At the end of the episode, she's revealed to be a robot sent by Obake to lure Hiro back into bot-fighting and away from heroics. Given that Obake has been behaving like an obsessed stalker toward Hiro for quite some time now, the implications of this Trina plan are particularly uncomfortable.
  • High Voltage eating raw fish in "Somethings Fishy".
  • Fred putting Wasabi's cold-pressed juice back in his cup after it's spilled on the floor (and on Baymax) in "The Fate of the Roommates". There's a good view of a band-aid and a toenail in it. Wasabi's reaction (running to the restroom to throw up) is justified.
• Take That, Scrappy!:
  • As annoying and bratty Richardson can be, karma fortunately always gets back at him:
    • He's on the receiving end of a lot of slapstick in "Big Hero 7" and gets his ass kicked repeatedly by High Voltage.
    • "El Fuego" has him threatened and beaten up by the episode's titular villain.
    • After spending the episode manipulating Fred and humiliating him in front of his cousin Olivia (whom Fred has a crush on), Richardson gets locked in a piano and forgotten thereafter the Supersonics attack.
  • Hardlight kidnapping and constantly insulting Chief Cruz in the former's debut episode.
• They Changed It, Now It Sucks!: Several fans were very disappointed and a bit outraged with Khary Payton replacing Damon Wayans Jr. as Wasabi and Brooks Wheelan replacing T.J. Miller as Fred, especially since everyone else of the original film reprised their roles. That's one of the reasons some fans tend to ignore the TV series. Though averted depending on the fans, who love Khary Payton as Wasabi (since they loved his work in Teen Titans (2003)) and tend to prefer Brooks Wheelan over T.J. Miller, especially after the latter was embroiled in a lot of controversy over the course of the late 2010s.
• They Wasted a Perfectly Good Character:
  • One lament that is carried over from the movie is that the series doesn't focus very much on GoGo, Wasabi, Honey Lemon, and Fred, instead of continuing to focus mostly on Hiro and Baymax. Whenever the series does focus on them, they rarely get any lasting form of character growth, even in the episodes focusing on them.
  • Tadashi's influence on the cast and history at SFIT is rarely brought up. Particularly in "Obake Yashiki", the episode is centered more around the comedic hijinks of the team dealing with their Absurd Phobias rather than the emotional impact of Hiro facing a Back from the Dead Tadashi.
    • Season 2 handled it way better, with Tadashi being mentioned more often and having a posthumous, but still crucial role in both the mid-season and end-of-season finales. He still has a posthumous Day in the Limelight in "The Present", which features Hiro in his first Christmas without Tadashi.
  • Abigail Callaghan, despite being Yokai's whole motivation in the movie who the original Baymax "died" saving, never appears in person in the series, only showing up in a photograph and being mentioned by her father.
  • Hiro and Tadashi's parents are stated to have died when Hiro was three years old in the movie. All that is known of them is a picture of their father with their pregnant mother appearing only in the Korean release of the movie. The series could've been a perfect occasion for seeing more of them as Posthumous Characters with flashbacks and seeing how Aunt Cass grieves her sister and brother-in-law while struggling to now raise her surviving nephew alone. They never once get a single mention throughout the entire series.
  • Chief Cruz's second-in-command, Detective Kato, was shown letting Big Hero 6 rescue his chief when he was kidnapped by Hardlight in the latter's debut episode and pointed out to him that Big Hero 6 saved his life. It could've been a perfect occasion to have a reluctant member of the force who doesn't agree with his boss on his treatment of heroes and could've been a potential ally. But in his next appearance, all of those precedent traits are erased and show him having just as much scorn and desire to arrest the heroes as his chief does.
  • Trina's role as the S2 finale's Big Bad was so rushed and barely developed before, due to the nature of the "Fugitives Arc" focused more on Chief Cruz throwing spanners in the works for Big Hero 6.
  • Sirque is an attractive Affably Evil Classy Cat-Burglar acrobat who stole Krei Tech's Project Silent Sparrow portal technology to commit heists, who only appears in one episode before "Go Go the Woweroo" reveals she was arrested offscreen.
  • Some fans feel that Hardlight would've been a more fitting Big Bad for Season 3 than Noodle Burger Boy due to the former's debut episode setting him up as a major threat, complete with a Wham Shot revealing his identity.
  • The introduction of Mayor Saito, the head of San Fransokyo in Season 3 brought up quite a few questions, specifically her whereabouts during the Fugitives arc and why she never attempted to stop Chief Cruz.
• They Wasted a Perfectly Good Plot:
  • Professor Granville and Obake's relationship is never explored in-depth aside from flashbacks, and they don't meet each other until the final episode of Season 1. It's not helped by Obake dying afterward. Probably.
  • Baymax says Obake's condition is treatable. Wow, there are a ton of possibilities for Character Development! Too bad, he refuses to be treated and (most probably) dies in the Season 1 finale.
  • City of Monsters reveals that Liv Amara we knew is an evil clone Di, while the real Liv is terminally ill and in stasis. How does Granville, her old friend, feel about it?
  • We don't see Krei's reaction to the Liv that he knew was a clone all along.
  • Chris hitting on Wasabi could've been expanded. Did he have a thing for him? Or was he faking it?
  • Monster!Karmi could've had a The Dog Bites Back moment and gotten back at Di for everything she's done to her.
  • The film shows Hiro has artistic talent when he draws the Silent Sparrow symbol. Given Karmi's own talent, this is something they could have bonded over.
  • Portal Enemy revealed that the first Baymax is still stuck in the portal. Sadly, this was never brought up again in the series.
  • Fred the Fugitive reveals that there was a reason why the Cruz family moved to San Fransokyo. This is never touched upon later, with Chief Cruz and Megan not even appearing in Season 3.
  • On that note, in Big Chibi 6, Cass brought up a good question "What about Megan?". As hated as Chief Cruz was, we are never given any exposition on what happened to them.
  • Trina only appeared three times before her Big Bad role in "Legacies", two of them being minor appearances that barely reference her revenge scheme, which makes her being the antagonist in the finale too rushed. In the same vein, Trina shares only one scene in total with Obake before his demise in Season 1. "Legacies" could've been a perfect occasion for a flashback that covered more ground on their father-daughter bond.
  • Similar to Lilo & Stitch: The Series, the show, in general, has received a lot of indignation from fans who were expecting the series to be as emotional as the movie. Prime examples include more flashbacks of Tadashi, how Hiro's parents died, how the nerd gang came together, learning their backstories and real names, and how Baymax came to be.
  • The show could have explored Hiro having some anger at Tadashi for his impulsive decision to run into the SFIT fire to rescue Callaghan.
• Tough Act to Follow: While the show is well received by many people, it's not as fondly looked upon as the creators' previous work on Kim Possible, with some people thinking it's trying too hard to recapture the magic of what made it work. This could also be said for the previous works in between the two shows, but it's noticeable here, especially from "City Of Monsters" onward.
• Unexpected Character: Gordon Ramsay and Alton Brown voice characters in an episode parodying cooking competitions early on in the series.
• Unintentionally Sympathetic:
  • Fred in "Big Hero 7". While blabbing his secret identity to Richardson was a massive bone-headed move on his part, he was expected to comply with blackmail to make up for it.
  • Hiro comes off as this in "The Dog Craze of Summer". While he should have been 100% focused on his job from the very start, he was saddled by Granville with three high-maintenance dogs and a really huge manual for the task at the last minute without prior notice. His poutiness when Cass takes his video games away and makes him take the job isn't unwarranted as he never actually volunteered to watch the dogs and he was forced into taking the job without being told what it was first. When Hiro and Baymax are out on the streets looking for Fermi, Hiro's refusal to read the manual is explicitly shown to not be out of laziness but out of a concern that they don't have time to go through it and that Fermi could be in a bad situation. Having the last of his dogsitting money stolen from him by a supervillain comes off as an unfair punishment after he got stuck in a floor retrieving Fermi and had most of the money taken by his friends for their help.
  • Hiro also comes off as this earlier in the series in Fan Friction. He's understandably embarrassed that his school rival is writing fanfics where he is her love interest (she is unaware he's the leader of Big Hero 6), but his friends say he should just accept Karmi has a crush on him and see if he can get an idea from her fanfics for his gear like they did for theirs.
• Unintentionally Unsympathetic: Professor Granville comes off as rather inconsiderate in "The Dog Craze of Summer." She dumps her three high-maintenance dogs on Hiro at the last minute with a ridiculously huge amount of instructions and supplies for just one day of dogsitting when she would known ahead of time she had a conference. There is no reason given why she couldn't have called Hiro over to her home, which, unlike the Lucky Cat, would presumably be prepped for three high-maintenance dogs to roam around and presumably has a backyard. That she had time to arrange a truckload of supplies to be brought to the Lucky Cat shows she had time that could have been spent giving Hiro a proper walkthrough of how to do his job at her place. She also merely says the dogs have "quirks" rather than taking 20-30 seconds before getting in the cab to explain the specifics. Adding to that, we see Baymax read the critical Mr. Pip instruction from the middle of the book when putting it on the front page could have allowed Hiro to retrieve Fermi when he saw him across the street. Instead, this causes the trouble to be dragged out until night. Given how easily the dogs seem to have been controlled with their toys at the end, the entire plot could have been avoided if she had merely left Hiro a 1 or 2-page list and only 1 or 2 boxes of supplies. Even her talk about Hiro having an abundance of free time and agreement with Cass about Hiro needing real-world work experience can come off as this considering that she is aware Hiro is the leader of Big Hero 6, who just stopped being fugitives from the law, and is thus entitled to some free time.
  • Hiro's teammates, with the exception of Baymax, can come off as this in this segment as well.
• The Un-Twist: Many fans had guessed that Liv Amara (or rather Diane) would be the Big Bad in Season 2. Perhaps expecting this to happen, the show does not make a big deal about this revelation and she's just casually shown to be the villain at the start of "Seventh Wheel".
• What Do You Mean, It's for Kids?:
  • Obake's suicide in the Season 1 finale is quite dark. Then you remember it's a kid's show.
  • The scene where Karmi gets mutated into a monster seems straight out of a horror movie.
• Win Back the Crowd: Of all the Marvel cartoons released during the 2010s decade, this has garnered the most positive reception not only due to the movie's positive reception but also how, just like the movie, Marvel has little involvement, leaving Disney itself to be more focused on crafting its world with the series.
