3[[folder:Hiro's suit]]
4Does Hiro's suit do anything besides allow him to control Baymax's flight mechanisms? He seems under-equipped (maybe he was trying to travel light so Baymax could easily tote him around but I would think someone with as much foresight as him would at least want some sort of auxiliary weapons system in case he gets separated from Baymax).
5* If the art book at least is anything to go by, no. The only thing it mentions is some extra tools for on the fly repairs (the small pouches on his belt), and flip open portable computers built into his gauntlets (which, unlike the tool pouches, might not have even been used in the film proper if i'm not mistaken). Whether on purpose or not, he's much like the traditional KidWithTheRemoteControl type characters, brilliant, but otherwise ill-equipped for anything when on their own. After all, like many have noted, the team never trained properly for the situations that they would eventually face; perhaps if they return to this universe in the future with a sequel, Hiro will have learned to build in some offensive/defensive capabilities into his own supersuit.
6* I know in the VideoGame/DisneyInfinity game he has control over his microbots, which I assumed he would build again to use as offensive/defensive weapons. Maybe in the sequel.
7* Hiro is TheKidWithTheRemoteControl, Baymax is his weapon.
8* He does seem to at least have some kind of [[VideoGame/CallOfDutyAdvancedWarfare Mag Grips]] built into his gloves to secure himself to Baymax's back with, but that's about it. If anything it just further reinforces the notion that Baymax is meant to be his only weapon.
9* But with Baymax able to call out his own attacks, Hiro might need to microbots after all...
10* Except, he doesn't. The microbots were all trapped in hyperspace along with the original Baymax.
11** Doesn't stop him from making more.
12** Even then, in the end Yokai's microbots are still around while he's carrying himself, while holding the portal and Baymax. He could create his own clearly on his own, so even if Hiro doesn't remember how he did it, he could reverse engineer them from the fallen microbots in the vicinity.
13* He's the pilot (both Baymax and the microbots) so all he need is command & control system (the computer and the brain interface) and repair tools. As long as he can pilot his gear correctly he can be that superhero he wants to be.
14* In the animated series, the gloves' electromagnets have been modified to both attract and repel, with the result Hiro can move around metal objects at will. For example, if a metal beam is thrown, he can pull it towards him or cause it to fly away into the sky. If he sets the magnets into overcharge mode and the object is light enough, he'll launch it really high.
15** In Season 2, he modifies the gloves to launch several miniaturised electromagnetic discs. These discs can pull large metal objects towards them or reverse polarity to launch the magnetised objects high into the sky.

18[[folder: Baymax's confusion/programming]]
19Why didn't Hiro or anyone else attempt to order Baymax to be a CombatMedic instead of just tricking him into being a warrior? Surely he'd either already be aware of the Geneva Conventions or able to research the concept the same way he found out how to help out Hiro with dealing with loss.
20** Hiro's the only one who knows how to program him. That's his speciality, while the others have theirs (Honey's is chemistry for example). And Hiro isn't really thinking clearly, since all he wants to do is apprehend the man in the mask. Plus with Baymax being a robot, Hiro reckons it's probably better to send him in as an attack unit. There's no reason he can't be both, after all.

23[[folder: Baymax at the end]]
24At the end how could Baymax still work when he had put his personality chip in his own rocket fist? Shouldn't he be going crazy on the fighting chip? Or if he had that removed should he be moving at all? Is there still a sentient Baymax floating around in the void?
25** The fighting chip isn't psychotic. It's still programmed to obey Hiro and Hiro hadn't given any particular command yet. Also, given previous events in the movie, it's entirely possible that Baymax pre-emptively altered the fighting chip - whether to contain part of his primary morals, to contain part of his primary personality, or simply to be able to act based on his personal desires and commands should his primary chip be removed.
26** As for "sentient," his battery won't last indefinitely. Also, Hiro gave the deactivation phrase "I am satisfied with my care," allowing Baymax to shut down his awareness.
27** It seems that Baymax still working after his personality chip is removed is done more than once in the movie actually. On the scene where Hiro orders Baymax to destroy Yokai before removing his personality chip, Baymax, when the chip was removed, could still say something in his usual personality. That is, before the container with all the chips is closed. It is possible that there is some sort of WI-FI connection between the chips and Baymax, which would explain why Baymax was able to put the chip in his hand while still being himself. However, there didn't seem to be an open container on Baymax during that sad scene, so that is still something to ponder about.
28** A simpler explanation is that the chip is something along the lines of an SSD. Normally, Baymax keeps his personality in his RAM, and only accesses the chip when he needs to either access or update his "caregiving matrix".
29*** When Hiro added the second chip, he had two databases to access, but the caregiving one was primary.
30*** When it was removed, his personality wasn't replaced until Hiro gave him an order, because the caregiver was still in active memory.
31** The animated series establishes that Baymax's endoskeleton has its own operating system, enough to follow or carry out simple instructions without his memory chip, but no more than that. It is most likely Baymax uploaded one final command into this endoskeleton, remove the memory chip and place it in the hand of the rocket fist, execute task before deactivation shutdown. It also appears Baymax can access the memory of actions performed via a system log, as he is perfectly aware of what transpired when his chip was removed from his body by Hiro.
32*** A new combat chip was created by Hiro in the animated series, one emphasizing heroics rather then direct fighting. How this chip differs from the previous combat chip is unknown, but most likely contains extra scenarios for being a superhero.
33*** And in the end, his caregiver persona was still active even with the chip removed, because Hiro DIDN'T give him a contradictory order.
34*** There seems to be an autorun-like command when disks are inserted or removed. This also seems to re-initialize the end-use (as opposed to kernel and system-used) programs (possibly why he reset the position of his head and appendages when the fighting chip was inserted). This could be why he still had the healthcare voice until the chip drive was shoved back in. After that incident, Baymax probably set up a RAID array in addition to locking the drive, so that his morality was on both disks in case Hiro actually managed to force the healthcare chip out somehow.
35** There may have been an actual change. We know that after the first time, Baymax took at least one precaution against a repeat occurrence (refusing to let Hiro access his chip slots). He may have given himself a patch that lets him continue running a program even if the chip is removed, at least for a while.
36*** He could also have put a one-time run script in his shutdown directory to line up the rocket fist and fire, possibly overriding the one to go to his dock.
37** Baymax did have an ace in the hole. He put the caregiver chip into the rocket fist so Hiro has something to rebuild him with.
38** Tadashi says that everything on the healthcare chip is what makes Baymax "Baymax", so it stands to reason that Baymax didn't put the chip into his rocket-fist until after Hiro consented to his deactivation...Otherwise, he wouldn't have bothered with the deactivation protocol in the first place, since we may assume that the combat chip wouldn't have any programming related to it.
39* Why did Baymax sacrifice himself at all? both his arms worked, he could have clung to the pod with one arm and still did the rocket fist with the other to blast them back to their world. him staying behind made little sense other than an emotional ploy.
40** There are actually several reasons this makes sense. First he is adding weight, slowing them down. Secondly, the position he would have to be in would create a good chance that the rocket would not fire straight. Thirdly, his extra mass and drag elements would prevent the flight path from being straight. But most importantly, is that this is Baymax. His own safety is unimportant to him, so even if saving himself causes a slight decrease in the odds of the two living people surviving, he won't take it. Alternately, it may just be a case of armchair logic. Baymax is a linear thinker. Hiro is panicking. They have only seconds before the portal is closed. They didn't think of that in time.
41*** The weight issue is negligible given that Baymax was extremely light built and could just have shed his leg armor.
42** Newton's Third Law: Every action has an equal and opposite reaction. If Baymax had grabbed on to the pod, the force of him being thrown back when he launched the rocket would have canceled out the force of the rocket pushing the pod forward, meaning they still wouldn't go any faster and still wouldn't get out in time.
43*** This is not correct. Baymax would have absorbed the shock and propelled the pod towards the opening.
44* Here's something nobody's brought up: Why didn't Baymax just deflate himself partially to propel himself, Hiro and the craft in the right direction? If he had started to do it when he grabbed onto Hiro's hand, they would have had more than enough time to exit the portal.
45** Speed probably. The rockets are much more powerful than a little gust of air from him deflating. It wouldn't have gotten them out of there before the portal collapsed.
46* Why didn't Baymax just tell Hiro that he was putting his personality chip in the gauntlet? Hiro was clearly very upset about leaving Baymax behind. Wouldn't it have been better for Hiro's emotional state to know that he could still take Baymax with him and just build him a new body? And why take the chance that Hiro wouldn't find the chip in the gauntlet?
47** He kind of did. He said "I will always be with you." Hiro took it in that "Tadashi is here" way". But Baymax is still very LiteralMinded, and he didn't understand that Hiro didn't understand.
48* Baymax just simply copied the contents of the green chip to the red one overwriting the existing content (probably except the program and drivers required to fire the rocket fist), since most of his battle gear is non-functional in this stage anyway. If Baymax is powered by the Linux operating system his programming can call the pivot_root(2) system call to move the operating system's current root folder to the red chip, and then the green chip can be safely unmounted and removed. You can try this trick using Linux live CD and a USB stick - you can copy the operating system to the USB stick, wiping it in the process, and move the system over from the CD to the USB stick, and then you can eject the disk without rendering the system inoperational.
49* Simple answer - [[ThreeLawsCompliant the Three Laws of Robotics]]. Law One: Baymax is programmed to keep his patients safe. Law Two: Baymax cannot obey orders that put his patients in danger. If he obeyed Hiro's plea he would seriously increase his risk of being trapped - indeed Hiro does barely make it out. Law Three: A robot should prolong its own existence as long as it doesn't conflict with laws one and two - so Baymax puts his personality chip in his fist thruster. As a robot he can be entirely rebuilt by somebody who considers him very important.

52[[folder: The microbots' power source]]
53Where do the microbots get their power? Since it appears that each microbot is individually powered, there is no way a battery that can fit inside can hold enough juice to run it for any decent amount of time.
54** Well, yes, this is one of the technical barriers that keeps all our technology from being Legos. Four-point answer, taken cumulatively. 1. Passive power accumulation through mini-solar cells or flywheel-style storage, augmented by 2. 'automatic' designation of some microbots whenever they form a large mass to act as conduits, like blood cells carrying energy throughout the body, further augmented by 3. actively seeking out power sockets or power lines to tap, but primarily by 4. being in a comic-book universe that will make exceptions to its physics whenever the result would be sufficiently cool.
55[[/folder]]
56
57[[folder: The cause of the fire]]
58Did Yokai start the fire to get his hands on the microbot technology?
59* Seems to be the implication. It may not have been intended to be as big as it was, but there you go.
60** But it is still left ambiguous enough that it's possible he didn't start it. We're not even given any clue as to ''what'' could have started it. All we're essentially told is a fire broke out. That's it.
61* A fire like that should have led to a thorough police investigation. Presumably somebody searched the ruins for incendiary devices and didn't find any. So either it was an accident, the police were incompetent, or Yokai managed to set the fire with something that was untraceable to the dogs that fire department investigators train to sniff out accelerants.
62* It ''was'' a science expo. Such an event that didn't have any flammable compounds, energy sources, or other fire hazards around would probably have been more unusual. Given Yokai's intelligence and expertise, any tampering or involvement he had could have easily been overlooked or masked unless the fire marshal was looking for something very specific.
63* Alternately, perhaps Yokai didn't plan anything at all, and was willing to bide his time to find a way to get revenge on Krei at a later date. The fire could have just been a fortuitous accident, and Yokai decided to just LetNoCrisisGoToWaste.
64* Maybe Yokai specifically made the fire huge to HELP eliminate proof.
65* On another thing regarding the fire, since Callaghan is revealed to be Yokai, and thus, survived the fire, why was he branded as dead, since it didn't seem like there was another corpse at the school.
66** He faked death so he would have free rein to carry out his microbot construction.
67** That doesn't account for the fact the authorities presumably found two bodies in the aftermath of the fire and one or both were so badly damaged they were unable to get a proper ID. The bodies would have been assumed to be Tadashi and Callaghan because witnesses said they were still in the building. So either there is a third, unknown victim, or Callaghan was able to rely on NeverFoundTheBody and NoOneCouldSurviveThat given that Tadashi also died.
68** Also, it kind of looks like there was an explosion, and, either way, it's unclear for how long the fire lasted. It's not too much of a stretch to assume that people may have thought that Callaghan, Tadashi, or both were burnt down to ashes or otherwise didn't leave enough remains behind.
69* Couldn't he have just waited? Hiro was clearly going to get into the school and would probably take the microbots to the lab. Callaghan could ''easily'' have asked if he could borrow a few of them to work with, replicated them, and gone to town. No need to fake anyone's death, and nobody would ever have probably thought to suspect him even if they figured out he was replicating microbots.
70** Hiro still would have found out through the microbots' shared signal, and then immediately know it was Callaghan because he asked to borrow some of them. Plus, now Hiro would be able to challenge him with microbots of his own, and Callaghan wanted to be sure he didn't have a potential threat to him.
71[[/folder]]
72
73[[folder: Controlling the microbots]]
74Given that the game implies he can rebuild the technology, why didn't Hiro rebuild his headband so that he could try to override or at least interfere with Yokai's mask?
75* That's a good question. Rather than go for Yokai's mask and sever his connection, a more sound approach would have been to try to intercept whatever bandwidth the microbots operate on. Probably just didn't occur to Hiro and he was only thinking in terms of dealing with the man, not the machines (which is something that only finally clicks with him at the climax).
76* Another possible explanation is that the microbots are linked to that particular headpiece for security reasons, like a bluetooth protocol, and Hiro would need the microbots to delink before they would accept commands from a new headset.
77[[/folder]]
78
79[[folder: Wasabi's nickname]]
80How do you "spill" wasabi? It's not a liquid, it's a sort of mushy substance.
81* That may well be how he earned it; somehow pasting himself with wasabi. He probably considers the action as "spilling it" regardless.
82* Could be that it hadn't adhered to the food, and it might have fallen off when he went to put it in his mouth. While unlikely, it's not unbelievable; some wasabi can be more like putty. He might have even dropped the wasabi as he was putting it on his food.
83* There are brands of "wasabi" that come in toothpaste like tubes. You can apply too much force to the tube and spill its contents all over the place.
84* You can spill all kinds of things on yourself that aren't specifically liquid, but still leave a stain. Ketchup. Cottage cheese. Egg yolk. It just needs to be kind of runny.
85* While he might have ''smeared'' wasabi on himself by accident, in casual conversation 'spilled' indicates his main point - it was an accident. Whereas 'I smeared wasabi on myself one time, people!' has a connotation of deliberate intent.
86[[/folder]]
87
88[[folder: Tadashi's death]]
89Yokai/Callaghan says Tadashi's death is his own fault. As harsh as that is, isn't he kind of right? I'm in no way excusing his actions, but it sounds like he wasn't counting on anyone trying to rescue him, let alone Tadashi, who clearly willingly went into the fire, and I don't see what reason he would have to lie about anything to Hiro. Especially if he didn't cause the fire to begin with (which, while implied, is left ambiguous enough that it is possible he didn't). So was it a SenselessSacrifice or is Yokai truly responsible to some extent?
90* I don't know if it would be murder, but if you kill someone while committing another crime, you're considered responsible. Since Tadashi died due to a fire that Callaghan set while Callaghan was committing robbery, it would count as manslaughter, as it was an "unlawful killing without malice or intent." This is according to Wikipedia, anyway.
91** Killing someone in the commission of another felony (in this case arson, intellectual property theft, and grand theft) is ground for invoking the felony murder statute in most states, including California.
92* Or maybe negligent homicide. He would be responsible for any deaths resulting from his arson, so it very well could still be considered murder. He could have orchestrated everything so that no one was there. We don't know a great deal about the event, but it seems like he might have waited until everything closed down before doing it. Of course, he probably hadn't planned on it until he saw the microbots and hatched the plan right there.
93** The movie novelization included a scene where Callaghan actually sees Tadashi run into the hall- and ignores him, even though the microbots could save them both. Deliberately abandoning Tadashi is more serious than accidentally killing him.
94** The fact that he's right on some levels is what makes the scene chilling. It's a NeverMyFault defense, so that Callaghan doesn't have to deal with the fact that Tadashi - who saw him as a father figure - died trying to save him, from a fire he caused.
95* All legal terms aside, Callaghan is ''not'' right. Tadashi went in to try to save Callaghan from the fire. He had no way of knowing and no reason to believe that Callaghan would've already procured a way to survive on his own. If the fire hadn't started, Tadashi wouldn't have needed to rush in and save him, and since Callaghan started the fire purposefully and with malicious intent, that means that Tadashi's death was his fault.
96** And y'know Callaghan could have ''saved'' Tadashi as well, since the microbots shielded him perfectly fine. In other words he allowed an innocent boy to die when he could have saved him.
97** And even if we ignore all these explanations, does that really excuse how callous the man was being? You don't just say something like that to a grieving family member, and not only was it basically him punching Hiro in the gut, but he was being pretty darn ungrateful, too, considering the only reason Tadashi went into the building was to save Callaghan.
98** Callaghan's perspective could be that Tadashi caused his own death by choosing to go into the building to save him rather than wait for the fire department to arrive.
99* Guys, you're missing the point. From Tadashi's perspective, it was foolish to run into a burning building to search for someone and expect any result other than tragedy. But from a legal ''and'' moral perspective, that's completely irrelevant if someone ''willingly'' sets the building on fire and/or ''willingly stays inside the building'' in order to commit a crime and with the knowledge that they are not in any actual danger. If it weren't for Callaghan's actions, the question of what Tadashi should have done would not have needed to come up in the first place. It's ''Callaghan's'' fault.

102[[folder:Portal Accident]]
103After losing contact with the test pilot, Krei Tech didn't even try to recover the space capsule or the dead pilot from the other side. Although a portal remains relatively undamaged, they neither repair it nor use it for future experiments. Baymax detects the pilot, who is still alive, behind recently opened portal. He finds the pilot hibernating inside her space capsule. Its life support system is still working fine, even after the prolonged mission.
104* Why did they presume that the pilot was dead just because they lost contact with her? It's possible that they lost contact because their equipment, not the space capsule, was blown to bits.
105* Why did they make no effort to find out what happened at the other side after they had closed the portal? If anything behind the last remaining portal is obliterated once it collapses, then their inaction make sense. In that case, any rescue/salvage attempt will be impossible. However, their portals don't work that way.
106** After the accident, you can hear the general telling Krei to dismantle the project and quarantine the island.
107** Also while they had clearly tested with small simple objects before (the hat, among other things), this is presented as the first large scale test where they were demonstrating a milestone progress to their funders. Any sort of recovery mission would have to involve equally complex testing... which they already know had 'failed'... and to boot, they had already seen that such large scale tests had a very significant and dangerous risk. At the end of the day, there probably isn't a right and easy answer and Krei, no matter how much money, ambition, or desire he has, likely couldn't keep the project going on his own. He wouldn't have been in a position where he was trying to meet a milestone if that were the case.
108** They may not have known that there ''was'' 'another side'. The life support gear on the capsule may have been intended to allow time for a safe recovery if the teleporter accidentally whisked its occupant to an icecap or ocean or other unexpected arrival point. It's not as if they'd have ever bothered to test a ''teleporter'' with only one portal running...
109* A better question is why the project apparently jumped straight from inanimate objects to human testing. Wouldn't it have made more sense to send a capsule with a monkey or dog or something before attempting to send a person through?
110** They probably had done tests with animals before that point. The accident happened at a demonstration for a reviewer from the Defense Department, which had apparently sponsored the project. They probably tested it with the hat just to give the reviewer an idea of what to expect, then went ahead to the main demonstration, which was a human trial.
111* Also about the accident, Krei checks the anomaly reported and declares it well within the acceptable limits. Was he saying the truth or just trying to be confident in front of his funder, and if he was honest, how much blame really does rest with him?
112** The film seems to try its hardest to subvert the idea of Krei being a CorruptCorporateExecutive. Considering how easily everyone else went along with the project after the anomaly came up, it's likely he was being truthful about it being within parameters.

114
115[[folder: The microbots in the fire]]
116So did the microbots protect Callaghan on their own accord or was he able to grab the headband quickly enough to make them do so? The way Callaghan explains it, it sounds like the former, but that just raises a ton of other questions.
117* I think you can see the headband on his head when he was talking about the fire. As it stands, the most likely scenario is that he grabbed the headband first, used the microbots to cause the fire, then had the microbots protect him.
118* There's two parts to this, but both are pretty easy to miss; first, after his presentation, Hiro leaves the headband on the edge of the stage. Later, when Callaghan mentions how he survived, the brief scene of him in the fire shows him put the band on (he lowers it onto his head) just before the microbots surround him. He's standing near the stage, where Hiro left everything earlier. Doesn't seem he used the bots to start the fire, but he wouldn't have needed to.
119[[/folder]]
120
121
122[[folder: Why Yokai?]]
123* So Callaghan, distraught with grief over his daughter's loss, decides to set a fire, fake his own death, steal Hiro's tech, and begin producing bots in the burned shell of the building while wearing a mask. He's a very intelligent man who probably planned for every contingency, and his death is never disputed so deciding to fake it probably wasn't a spur of the moment thing. The big question: What does he gain from being assumed dead? Why fake his death? If anything it hinders him- he is entirely cut off from the former access to lab tech, raw materials and brilliant minds his prestigious college post and social contacts would have provided him. And what was the point of the mask? The benefits of a secret identity kind of require a regular identity. The use of the microbots, which were last seen in that mysterious fire, would sooner or later blow Callaghan's cover to anyone doing a thorough enough examination of everyone who went to the expo. It might be to strike terror into people's hearts, but he never really does anything stressing this supernatural note, and in his confrontation with Krei he flips the mask aside to talk to him face to face.
124** Offhand, ditching the burdens of doing anything but Working Towards Revenge seems a fair trade-off for Callaghan. Consider for a moment how much mental effort it takes for a serious monomaniac to maintain the college post and social contacts mentioned above; and recall that once Krei is slain little if anything else would matter.
125** Faking his death also allows him to manufacture the nanobots at a continuous pace without arising suspicion. At the college, someone would start to wonder why he was going through so much raw material or why he was producing so many nanobots. This way, he gets to his goal faster and can just steal small supplies of materials all over the place. The mask is probably just to ensure his ruse isn't revealed too early if someone sees him, and it makes for a dramatic reveal when he finally confronts Krei.
126** Also, it's important to note that while he's intelligent, he's also very emotional. People will do crazy things no matter how intelligent they are.
127** It also plays into his mentality of an avenging spirit.
128** If he's seen as just a mysterious psycho in a mask, his motivations and goals are unknowable. If he's known as Callaghan turned evil, his motivations and goals could be fairly easily deduced by looking at his history.
129*** Also, if he went as himself, no one would waste time suspecting an entirely different person, as the Six did before they saw him unmasked.
130** In addition, Callaghan's using some pretty distinctive technology. Hiro realizes that the person who stole his nanobots also set the fire pretty quickly, but he never realizes it's Callaghan until the island. If Callaghan had "stayed alive," Hiro or his friends could have suspected Callaghan and went to the cops.
131** Moreover, by burning down the building, Callaghan makes it seem that the microbots have been destroyed. That means that even if witnesses report sighting of his microbot-swarm, it's less likely that any of the few science-fair attendees who saw Hiro's presentation will connect the reports to the boy's invention. The longer he can keep the nature of his secret weapon a ''secret'', the better his chance of pulling off his scheme before somebody invents a jamming signal or other counterattack. Concealing his own identity and faking his death further breaks that link between Yokai's mysterious black waves and Dr. Callahan's latest would-have-been-student's microbots.
132[[/folder]]
133
134[[folder: Why target the students?]]
135This just keeps bothering me. Why didn't Yokai / Callaghan go after Krei right away? And why did he target the students? Unless I'm forgetting the movie already, the students didn't really do anything. I know Hiro broke into the warehouse, but that was it. After that, he seemed to have aimed to kill Hiro and the others for no reason besides they were there. He might've even gotten away with killing Krei had he left the students alone because they wouldn't have learned his identity. And even if they did eventually learn of it, the crime would've already been done, so they couldn't do anything about it.
136* He planned his revenge in a very specific way - using the transporter gate. He had lots of chance of killing Krei, but he won't be satisfied with that. After the island is closed, the gate seemed to be destroyed (he took them from the ocean) and he took time to rebuild them. He isn't specifically target the students, his main target is Krei; he just didn't mind killing anyone else in his path. In short, he was afraid of being found out before his plan could be carried out. Note that he probably thinks they are dead after their car falls into the water.
137** He also didn't just want to kill Krei, he wanted to destroy his life. He planned on destroying Kreitech's new building all along.
138* He also targeted the students because they were in the way and at risk of exposing him. In every fight except the last, he only fights long enough to make his escape or until he feels he was risking exposing himself.
139* Fred was right: They knew too much. Pay close attention when Honey takes a picture of Yokai, or you'll miss it: After the flash, Yokai's head snaps to her and then he hurls the unit at them. He attacked them because they'd seen him and taken a picture of him.
140** Honey wasn't the only one who took a picture of Yokai: Baymax scanned him closely enough to get his blood type. Yokai would have been familiar enough with Tadashi's work to know that Baymax can do a medical scan; for all he knew, Baymax could also have picked up genetic information which would clearly expose him as Callaghan. Thus, Baymax (along with anyone with him) had to be dealt with ASAP.
141** He should have also recognized Hiro. Hiro built the tech he's using, and so is a serious threat that he had the opportunity to eliminate.
142** And it's pretty clear that Hiro is (at least for a while) as dead-set on revenge as Callahan himself is. The boy isn't going to stop, and Callahan isn't either; the latter is bound to have concluded their conflict is inevitable.
143[[/folder]]
144
145[[folder:Baymax's Fighting Style]]
146During the final battle, Baymax calls out his own attacks instead of relying on Hiro telling him what to do. Is that supposed to indicate CharacterDevelopment or something else?
147* Likely. Over the course of the movie, Baymax does become more human-like, though not so much, we'd forget he was a robot. Hiro was able to teach him a bit of slang, so it's possible he could learn how to call his own attacks too.
148* Also, by that point, he had advanced far enough to override Hiro's directives. After the whole 'kill Yokai' scene, Baymax is implicitly always in control of his own actions and directions. He's fighting but he's not willing to cause any harm.
149* He may also be keeping Hiro apprised of his moves, so the boy will react appropriately and know exactly how to lean or duck to avoid the scattering microbots. They're tiny, but could still sting if one hit Hiro in the face.
150* Another possibility is that Hiro installed a version of the neural control system that linked him and Baymax so that he could coordinate attacks and relay commands with a thought, rather than vocal commands

153[[folder:The Hamada name]]
154Why is Hiro's aunt named Cass Hamada? Hamada is an Asian name, so it's probable that Hiro and Tadashi inherited their last name from an Asian father, which would make Cass the sister of Hiro and Tadashi's white mother. So why does she have the last name Hamada, instead of whatever was Mrs. Hamada's maiden name?
155* She was [[https://www.youtube.com/watch?v=9zYVrAa-J0Y originally supposed to be their mother]], for what it's worth. Now that she's officially their aunt, it's possible that she isn't actually blood-related to them at all (she could've been their father's adopted or stepsister, or sister-in-law), which makes her relationship with the brothers even ''more'' heartwarming. (Doylist answer: they really wanted to [[WesternAnimation/Frozen2013 re]]-reuse [[WesternAnimation/{{Tangled}} Rapunzel]]'s character model, I suppose.)
156* She might be their father's sister. The Hamadas could have a distant Japanese ancestor who passed down the name but enough white ancestry that Aunt Cass looks white.
157* Or she's the sister of either parent regardless of ethnicity, and just has that name to drive home the {{Americasia}} setting.
158* Or the white side simply had a last name like that for some other reason such as immigration. In real life, there are white families with names like Lee, for instance, which are usually associated with Asian names.
159** Well, no, there's an English name Lee, as in Robert E., who wasn't Asian in any way, and there's a Chinese name Lee, sometimes transliterated as Li. The two happen to sound alike, but have no other connection. There's no English name Hamada.
160* If a family picture seen in the background is any indication, Mr. Hamada is white and Mrs. Hamada is Japanese, meaning Cass comes from the father's side of the family.
161* I figured she was like half Japanese and half white, as she doesn't look 100% one or the other.
162* Cass might be a corrupted nickname of Kasumi (or any other name beginning with a "cas" sound), at least making her name fit in with the rest of the known Hamadas.
163* Remember also that San Fransokyo is a very racially and culturally mixed city. Presumably plenty of people of all races have Japanese names because of a single person in their family history.
164* She could be their aunt-by-marriage, married to Mr. Hamada's (presumably now-also deceased) brother.
165* Adding another dimension of depth to the mystery is the fact that Honey Lemon, a seemingly white/non-Hispanic girl pronounces Hiro's name with a more accurately Japanese spin on the "r" then Hiro does himself.
166** Genesis Rodriguez, Honey Lemon's Venezuelan and Cuban voice actress, has stated that Honey Lemon is Latina and that her flipping the 'r' in Hiro's name is a nod to that. Also, in the scene where Hiro showcases his microbots for San Fransokyo Tech, Honey Lemon's pronunciation of "photo" -- with pure "o" sounds instead of the messy dipthongs of English -- sounds like she's saying the Spanish word "foto".
167* Wait, when did the film (or any supplementary material or the show) indicate her surname is Hamada? Okay, the Disney Wiki (which isn't an official source) used to claim that but not anymore.
168* Another possibility is that she kept her surname because she married "down" (in Japanese culture, the family takes the last name of whichever spouse is "higher" in social status)

171[[folder:How Long Ago Was the Accident?]]
172Just how much time elapsed between the portal accident and the events of the movie? Assuming the accident wasn't just before the expo (Callaghan seemed to be emotionally stable, not like someone whose daughter just disappeared in a freak lab experiment), it almost implies that several months elapsed between the demonstration and when the capsule was rescued by Hiro and Baymax. How much time did Abigail spend in the void, and why didn't she suffer any physical effects like starvation or dehydration?
173* Callaghan's emotional state may not mean much unless we were talking about a very short time frame, as some people are surprisingly good at hiding their emotions. As for how long ago the accident was, it's really up to guessing, but I'd say a few months at most. Also, she did have to be hospitalized, so she likely suffered some ill effects. Perhaps being in suspended animation slowed them to some degree.
174* There's also the question of how time or its effects might differ in the Void. Who knows what weirdness might be in effect there?

177[[folder:GPS Baymax tracker]]
178Baymax says he contacted Hiro's friends to provide him support, and they say that's why they came over when Hiro finds Yokai the second time. But how did they find him at the dock? It seemed as though Baymax had merely sent them each a phone call, in which they would have gone to Hiro's house instead and found him not there. Did Baymax send them some kind of GPS signal to let them track him down? Why do that if he was only asking them to come over?
179* If I remember correctly, they did pass by Hiro and Baymax when they were driving, but Hiro was afraid and ran away because he didn't know it was them. Perhaps they followed him and that's how they found him and Baymax at the dock.
180* It actually would make sense for Baymax to update the friends with a GPS location. He is very literal minded at this point, so his goal is to get the friends to Hiro's location. If Hiro's location changes, he brings them to the new location.
181* I believe the scene with Hiro and Baymax sneaking to the docks starts with their car in a stakeout position. The implication is that they tailed him until he stopped at the docks.
182[[/folder]]
183
184[[folder:Secret Robot Man]]
185Why was Hiro hiding Baymax from Aunt Cass? All he had to tell her was that Baymax is one of Tadashi's inventions. I'm sure she wouldn't have a problem with him around.
186* My personal guess is he was eventually planning to return Baymax to the lab, but wanting to catch Yokai changed that plan. Or maybe he didn't want her to know about creating the superhero costumes/gear and hiding Baymax just made that easier.
187* At the time, Baymax was low on battery and, as we saw at the front door, would have likely told Aunt Cass what had happened. Hiro was probably hiding him/getting him away quickly to avoid that.
188** That seems to be the obvious answer - Hiro didn't want Baymax to say "We jumped out a window".
189*** This is confirmed, since Hiro's original plan was to have Baymax tell her that they were at school all day. He only tries to hide him once he realizes that at his current power level, he can't lie.
190*** But then again, wasn't Baymax pretty much spewing nonsense anyway due to his low battery? If Cass chose to question him about the window comment, couldn't Hiro have easily waved it away?
191** He's a child who's just been attacked by a masked supervillain who can control micro-bots. He's obviously not thinking clearly. Plus he has a reputation as a delinquent (Cass does have to bail him out of jail at the start) so she's not likely to believe that kind of lie.

193
194[[folder:Mr. Incredible Knows Your Fitting Woes]]
195If Hiro was having so much trouble fitting Baymax into his supersuit, couldn't he ask Baymax to deflate himself a bit so that he'd fit?
196* Deflating enough to fit into the suit may have made it difficult for Baymax to walk.
197* I don't see why it would, since Baymax appears to be able to selectively inflate parts of himself. When deflating himself to fit through the window, his head doesn't deflate. When his arms have holes in them, his body doesn't deflate. He's not one big balloon but several separate ones, closed off at the joints. All Baymax would have to do to fit in the suit would be deflate himself, get put inside, then re-inflate until the suit won't let him go any further.
198** One minor correction is that his head isn't inflated. It's a solid piece, like the "skull" to his carbon fiber "skeleton".

201[[folder:Baymax's battery]]
202It seemed like Baymax's battery ran out extremely fast when it did (and I know that Hiro said it wasn't the most efficient kind). We don't know what time it was when he followed the microbot, but it looked to be midday. Presumably it seems to have taken him and Hiro at most half an hour to get to the warehouse. They spent five minutes there then went to the police station, upon which Baymax ran low. Then when Hiro gets back home, it's dinnertime and the sun is down. Did it take them several hours to get to the police station? The trip didn't seem that long, no more than 2 hours totaled with the time to the warehouse. And if Baymax was already low at the police station, how did he have power at all upon getting home if it took several more hours?
203* When they're escaping from the microbots, Hiro runs Baymax into objects multiple times. Perhaps he damaged the battery a bit. Or maybe Baymax isn't really meant to walk distances (even if it's a short distance for a person), so him following the microbot caused him to exert more power than he's typically supposed to. As for why he still had power when they got home, Hiro probably helped him along instead of making him walk the whole way.
204* Extremely fast compared to what? Baymax can fit into a suitcase when he's deflated, so it's not like he'd have a huge rack of batteries in there. Having a robot the size of an adult human walk around for even half an hour is pretty impressive for a few internal batteries. Also, it didn't look like Baymax's charger was plugged in at the beginning of that scene, so his batteries were probably partially expended to start with.
205** Agreed. During his introduction, he is said to have Li-Ion batteries. It's usually recommended that Li-Ion batteries are about half charged if they will be in storage for some time. However, given that he did in fact charge in one minute flat after getting back, he probably now has super-capacitors, thus rendering this point invalid.
206* Baymax did try to use a defibrillator on Hiro. That would take a lot of power to manage and maintain, even if the energy wasn't used.
207** Baymax also had to deflate and inflate himself several times, possibly more offscreen to deal with his leaks. Given his size, that could eat up a lot of power.
208* It's also worth remembering that at this point, Baymax has been essentially been sitting in Tadashi's room on standby, since (before) the accident. It stands to reason that his battery was getting low before they went out adventuring and ran down what power he had left as a result. It's only after that that Hiro plugs in his docking station thingy, and subsequently Baymax doesn't have any power issues.
209** Tadashi went to the trouble of bringing Baymax home in his docking station. He must have been doing beta testing, which would take time. It wouldn't make much sense for the docking station to not be plugged in.
210*** Tadashi was only shown working on Baymax at college, and we didn't see Baymax at home until after his death. It seemed like Baymax and his docking station were only taken to Tadashi's house when his family claimed his possessions. It would be pretty hard to work on Baymax without the tools and resources available at the school labs, after all.

213[[folder: Baymax's speed]]
214Baymax himself says he's not fast. Yet moments ago, he was apparently fast enough to stay far ahead of Hiro. Heck, if Baymax is that slow, how did he even get out the door in just a few seconds?
215* The part where Hiro hears the doorbell ring (signaling Baymax leaving) was probably just to avoid a sixty-second long shot of Hiro and nothing happening. As for why he was ahead of Hiro, we could see that Baymax didn't stop and stumble to avoid obstacles. Even at the part where Hiro comes close, he slides because he was running so fast. Baymax had a few seconds of a headstart.

217
218[[folder:Hiro's Self-Esteem Issues]]
219Even after the events of the movie, Hiro is still suffering from self-esteem issues. He never makes friends outside of Tadashi's group and he even starts behaving like Tadashi. If there was a sequel, who's to say that Hiro's problems make him an identical copy of Tadashi?
220* That seems like more of a FridgeHorror scenario, not really a question.
221* I don't think Hiro has self-esteem issues at all. In fact, there are times in the movie where he seems downright cocky.
222** To your point about him only being friends with Tadashi's group...he's a kid genius who spends all of his time engineering bots and illegally betting on fights which he swoops into and dominates. It would be awfully difficult for him to make friends with average 14-year olds who aren't as intelligent, so it makes sense that he bonds with his brother's friends.
223** As for him acting like Tadashi... that's his big brother. He's a young boy who idolizes his big bro, who we see established as a pretty amazing guy (smart, kind, heroic). It makes sense both realistically and story-wise for him to emulate his brother (esp the lessons he learned from his brother about thinking outside of the box and being heroic).
224[[/folder]]
225
226[[folder:Baymax programmed for what?]]
227* Not sure how to ask this, but I was confused when I saw the scene where Hiro ordered Baymax to attack Callaghan, looking at Baymax's eyes and the sign in the fighting disk it's pretty obvious that Hiro programmed Baymax to kill showing no mercy, but how could he do that since he made it by downloading moves data from a martial-arts sensei video? Senseis generally have a more wise philosophy about fighting and Baymax's attitude is very opposite to Sensei's philosophy.
228** Hiro programmed Baymax with the man's moves, not his philosophy, and the combat chip didn't have any personality routines to it. In other words, at the time all Baymax knew was how to follow orders and kick butts, not question those orders or decide whether the butts should be kicked or not.
229** Also, what does it matter if senseis are "generally" wise and non-lethal? Maybe this particular sensei made some comment about how deadly force is sometimes necessary. We didn't necessarily see the whole video.

232[[folder: Teleporter room]]
233How was Honey able to see into the teleporter room? the door was closed, with a very small crack, and the way the door opened, all she couldn't have been able to see the broken teleporter itself.
234** If it helps I remember the door being partially open.
235** She would have seen the control room, which had a working computer in plain sight. That's interesting enough.
236** There was some light coming out of the partially open door - that's enough to catch her eye and make her think "I should check in this room."

238
239[[folder: Baymax deactivating in the climax]]
240Why was it necessary for Baymax to deactivate in order to save Hiro? Couldn't he have fired his rocket fist and sent the two humans in his care to safety without deactivating? He's used that weapon dozens of times already without needing to deactivate or do anything special.
241* Sure, he could have fired the rocket fist without deactivating, but he wanted to make sure Hiro would be okay and his protocol for that requires that the patient say he's satisfied. The deactivation has nothing to do with the rocket punch and everything to do with closure.
242
243You mean, he couldn't leave Hiro (his patient) until he heard his patient say he was satisfied? The act of separating from him was the action that required the phrase?
244* Yes. He also presumably wanted to be deactivated since the alternative was to float around in space, conscious, forever (or at least until his battery died, which might take a while).
245* I took it as a more general case of ICannotSelfTerminate. Baymax ''knows'' that the rocket punch will leave him stranded on the wrong side of the portal. He knows that eventually his battery will run down and he'll deactivate from lack of power. Hence, his programming counts the rocket punch as a Deactivation Attempt. He cannot deactivate unless the patient is satisfied, and thus he cannot use the rocket punch (in this situation) unless the patient is satisfied.
246* Baymax has no problem leaving Hiro's presence to follow the lone microbot's "compass" earlier in the film, so it's not that he can't leave a patient unattended. But Baymax's download on grief counseling probably included knowing that DyingAlone is traumatic for humans, both if they're dying themselves and if they're bereft. He doesn't want Hiro to be haunted by the notion of Baymax spending his last moments adrift, alone and conscious: something that was probably a contributing factor to ''Callahan's'' own emotional breakdown, imagining Abigail being similarly marooned.
247** It's implied he followed the lone microbot because Hiro had sarcastically told him that finding out what it was pointing toward would improve his emotional state. Which just further implies that Baymax has to remain with his patient unless he's given an express order to the contrary.

250[[folder:Hiro's first robot fight]]
251What counts as a "loss"? Why did he "lose" when clearly his robot can reconsitute itself from the 3 parts? He didn't even touch them and they just came back together for the second fight!
252* It's possible that Hiro just wanted a chance to observe Yama's fighting style and see how his robot worked before actually taking him on. He "loses" the first fight because he knew that if he could get to know the patterns and tendencies of his opponent, he can find out exactly how to defeat him in the next round. As for the robot being in 3 parts: Hiro is the only one that knew that it wasn't broken after the first fight. Everybody else thought he had lost. His reason for engaging Yama in another fight instead of just ending him in the first one might have been that it would get him more money (since Yama might raise his wager), and if nothing else, it might just be because it would have more of a dramatic flair to surprise everybody like that.
253* Hiro was very clearly hustling. Sure, he could get back on his feet and win the first fight, but he wanted his opponent to become overconfident and bet even higher on the second fight.
254[[/folder]]
255
256[[folder:Hiro's revenge]]
257What's up with this IfYouKillHimYouWillBeJustLikeHim nonsense? Killing Yokai will ''not'' make Hiro like him. Where Hiro would be satisfied enough with Yokai's death, Yokai proves to be willing to murder ''everyone'' who happens to be in Krei's headquarters the next day. What, you think a building that big in a day that busy is ''empty?
258* No one in the film actually tells Hiro "IfYouKillHimYouWillBeJustLikeHim," just that "Killing him would be wrong." However, killing him would have made him like Yokai in the sense that they both wanted to kill someone in revenge for the death of a loved one -- that's not right, no matter how small the accompanying body count would be. The fact that Hiro wouldn't have been willing to harm innocent civilians in the process makes him different, yes, but not completely different.
259** But that's the question exactly: How is it wrong to kill a man who has stolen your work and then tried to ''murder you'' -- and later on your buddies! -- not once, not twice, but ''three times'', and who, once you have him in your mercy, still has the gall to insult your brother, the last blood kin you have?
260** You pointed out the answer. At. Your. Mercy. Had Yokai broken his neck in the melee it would not have been nearly as serious an issue. If Hiro blew his stack and started beating the helpless Callighan it would have been worthy of censure but far from any MoralEventHorizon. But cold blooded murder of a helpless prisoner because he managed to anger his captors? Not cool. Not cool at all.
261*** And as pointed out below, just because he was being a jerk about Tadashi's death doesn't make it ok to murder him without hesitation.
262* It never even remotely comes up -- by the time they even know that Yokai is motivated by revenge, Hiro isn't motivated by revenge any more.
263* Apparently everyone just takes ThouShaltNotKill as a general rule. It's kind of a subtle thing, if you think about it. The good guys know that they're superheroes, and practically every mainstream superhero obeys ThouShaltNotKill, so they obey it too.
264* I think the issue is more that Hiro specifically tries to kill him ''after he's already defeated and disarmed''. They had already gotten the mask away from him, so it would've been relatively easy to apprehend him and hand him over to the proper authorities instead of going ComicBook/JudgeDredd on the guy.
265** Ah, but that's the thing: Even after he's been defeated and disarmed, Callaghan ''still'' has the mouth to insult Hiro's brother. He's stupid/arrogant/unrepentant enough to taunt Hiro like that, he deserves whatever punishment Hiro seeks to inflict.
266*** Because the villain is bad, it's okay to summarily execute him? More generally, do you really not understand why the other members of the team might have a problem with Hiro committing something that the state of California calls first-degree murder? Killing another person deliberately, willfully, and with premeditation, which is what Hiro would have been doing, is first-degree murder. Hiro would not have been able to claim self-defense, because Callaghan was at his mercy at the time.
267*** All those people whose fathers, mothers, brothers, and sisters Callaghan ''killed'' when he uproots Krei's headquarters -- why don't you ask them that question?
268*** It should be pointed out that Krei's new building was empty. Callaghan attacked during a grand opening ceremony, that's why Krei was at the podium with champagne.
269*** See this film's NightmareFuel entry about Krei's new HQ (the one that starts with "Not to mention...") That part of the discussion is settled.
270** I've always taken it as, after seeing the video recording of Tadashi trying to get Baymax to work, Hiro realizes how much time and effort his brother put into making him functional, and all for the purpose of helping others, healing the sick and injured, because of how much the world needed him...and how he threw Tadashi's dream away, disregarded Baymax's purpose, by removing his healthcare chip and ordering him to kill Callaghan. That's what shocked him out of it, not whether Callaghan was worthy of mercy or not.
271** Erm might does not equal right. Hiro and his friends have no authority. They're just vigilantes in superhero outfits. Callaghan is a criminal and should therefore be turned over to the police, with his punishment decided in a court of law. Killing is wrong unless it's in self defence. And Callaghan was at their mercy ''until'' Hiro ordered Baymax to kill -- the ensuing distraction allowing Callaghan to escape.
272* At the time, all they ''knew'' about the plan was that Callaghan had stolen the microbots and was using them for rebuilding the portals, and was willing to kill them for seeing too much. They didn't know what he planned to do or his motives. In the accident Callaghan caused, Tadashi ran back into a burning building. Callaghan was deeply insensitive in his words to Hiro, but he certainly never intended for Tadashi to die. They beat him. Yet Hiro ordered Baymax to kill him even though they could have just handed him over to the cops and stopped any destructive plans dead in their tracks. You ''can't'' let a 14 year old boy make a decision like that - it would follow him through his entire life.
273[[/folder]]
274
275[[folder: How did Yokai know that Hiro and the others would be there?]]
276Alright, I can understand why Yokai would be out in the ocean at night (Probably test-driving to see if he has enough microbots after evacuating the AbandonedWarehouse -- he probably used them to get to the island) but he seems to know that people would be right there (or at least Hiro). How did he know that?
277* He didn't, but the gang sure was making a lot of noise. They'd be kind of hard to miss.
278* If you pay attention when he makes his escape, he's pulling a piece of the portal device out using the microbots, similar to the one he brought across during the scene at the docks. He was there for the portal device, and the kids just happened to be in the wrong place at the wrong time.
279[[/folder]]
280
281[[folder: How did nobody spot them during that chase scene?]]
282While most of the chase was around abandoned areas of the city and industrial areas at night, they clearly went through residential areas as well - Shouldn't some civilians have heard the noise and looked outside to find a man floating around levitated by something? I know that Yokai has RefugeInAudacity going for him, but surely ''multiple'' unrelated civilians ''and'' a random car being hurled around should warrant an investigation - especially since there are probably security cameras around that would capture footage, and there would be multiple unrelated things, meaning this would clearly throw "Elaborate Hoax"/"ViralMarketing" theories out the window fast.
283* The chase scene, especially when Gogo took over, was ''fast''. By the time anyone woke up and stumbled to their windows, both the car and the shadowy black man chasing it were long gone. Maybe the hurled car would warrant some investigation the next day, but no one actually saw said shadowy black man hurling it. The police probably passed it off with a more mundane reason. And most security cameras for local stores focus on the doors rather than the roads (you know, to see who's coming in or going out).

285
286[[folder: Hiro's resources]]
287I can buy that Hiro is intelligent enough to be able to design them, given that he's basically [[ComicBook/IronMan Tony Stark]] on roids, but it raises a major question: How on earth does he have the resources to afford the stuff he does? We can assume that the family isn't particularly wealthy, as a cafe isn't exactly a business that makes piles of money. Take the microbots. If he had made just a couple hundred it would be within believability, but he makes tens of thousands of them over a period of what can't be more than a week or two. Even if we figure that each of the microbots only cost a dollar to create, even a single trashbin full of them would cost several thousand bucks, and he has maybe a dozen of them. And that's not even factoring in the time it takes to manufacture each of them or the time and money that would have to go into experimental versions he would have inevitably had to build before getting started on the final versions.
288
289Similarly, how could he afford a 3-D printer capable of creating ''carbon fiber armor'', in addition to multiple advanced computer systems? None of that stuff is cheap.
290
291* Judging from the size of the stack, the film opens with Hiro making about $30k in a single 2 minute long back alley bot fight. He plans to attend other fights that same night. He could easily pull in $100k per week if the bot fighting market is as large as it's made out to be.
292* Also, TwentyMinutesIntoTheFuture. Technology may be cheaper.
293** For his microbots, he could at least have used any resources the university might have as well. Notably after the group decide to become superheroes, they know about Fred's wealth - so he could finance anything they may need. He's over eighteen so he likely has plenty of money of his own.
294[[/folder]]
295
296[[folder: Interdisciplinary Roboticists]]
297So, the microbots are basically mind controlled. Putting aside the fact that Hiro effectively created functional ESP, how was he capable of creating something like that? This isn't one of those "uses brainwaves to move the ball" toys, the microbots are taking extremely specific complex instructions from whoever's wearing the headband. You'd have to be a professional neurologist with specialized equipment to map brainwaves like that, yet Hiro manages to apparently build one from scratch ''as an afterthought.'' Being a genius with tech is one thing, but this crosses over into medical science, which Hiro wouldn't have any background in.
298* Maybe one of his parents was a neuroscientist or something along those lines?
299** [[FridgeBrilliance Maybe that's where Tadashi got the idea to make Baymax a medical robot?]] Maybe one of their parents was a neuroscientist who tried to cure a cancer the other one had.
300* Well, this ''is'' TwentyMinutesIntoTheFuture, so it is possible that the tech was already around, it just wasn't used for a lot of applications. What Hiro did was possibly like taking a computer and modifying it into a specialized gaming console: You are just taking already-existing tech and using it for a different purpose. Heck, maybe there was already a Human-Machine Interface specialist in the University who was just not shown on-screen and that gave him the headband's "mind-reading" technology, and then it was trivial for Hiro to adapt the controller for his fighting robot into the new tech.

304[[folder: Baymax' purpose]]
305
306No denying that Baymax "2.0" is awesome, but is Hiro ever going to use him for what Tadashi originally designed him for, which I presume was to help around at hospitals and retirement homes etc?
307* As noted below, Baymax was a prototype. Tadashi almost certainly has all of the schematics and such backed up somewhere, along with the programming, so it wouldn't be too difficult for somebody else to continue his research and put Baymax into production as a medical assistant.
308

311[[folder: Only one Baymax?]]
312
313Baymax was created to help sick and injured, like Tadashi says he's "gonna help ''alot'' of people". There's only so many people ''one'' robot can help though, wouldn't the logic thing be to make many Baymaxes? Obviously it wouldn't be easy considering how much time Tadashi spent to make one Baymax right, but there should at least have been a mention that Baymax was meant to be the first of a new type or nursing robots or along those lines. And Hiro apparently got Baymax' body and motorism down on his first try.
314
315* Given that Tadashi's group was meant for cutting edge prototyping and that Tadashi said something along the lines of it going to be a prototype before his untimely death...
316** I think it's pretty clear that Baymax was essentially a prototype, the purpose of which was to iron out the kinks in the system before putting the robots into mass production. As seen in the log, Tadashi had only ''just'' gotten him functional by the time the movie started, so chances are he still intended to make a few improvements before submitting it to a company for any sort of mass production. The only real hiccup would be hashing out who legally own the rights after Tadashi's death; Baymax was created at the university, presumably using university resources, so they'd have a valid claim to ownership of the plans, if not Baymax himself.
317*** Legal stuff like the ownership of any patents resulting from a research project are usually settled in advance, by means of contracts and wavers and such. Typically it would be split between the researchers, the institution, and any corporate funders.
318** As for Hiro's ease in creating a new one, I think it's safe to assume that Tadashi had a ton of documentation and schematics produced, which would make it a lot easier for Hiro (who's basically a savant when it comes to robotics) to build a new one, especially as stuff like 3D printing is apparently widely available and cost efficient. The real difficulty would be in Baymax's programming, and Hiro already has the memory chip for that. And even if he didn't, Tadashi would almost certainly have that stuff backed up someplace.
319*** Hiro also used a computer to scan Baymax a few times when creating the latter's armor. Those scans could easily help Hiro recreate the blueprints, given that Baymax's vinyl body was transparent enough for Hiro to see his skeleton and batteries in the university lab. We've also seen that Hiro is a genius at adapting others' designs, taking Callaghan's work and applying it to create the microbots in the first place.
320* Hiro had the hard part; the chip, which would probably have all the schematics on it anyway. He had his friends, who would be just as eager to help make Baymax again. They all knew exactly what they were going for when they made the body. It probably took a few months, but once somebody has made something, it's a lot easier to make a new one.

324[[folder: Impromptu Weirdness Censor]]
325
326* The scene between police officer and Hiro when trying to explain 'a man in a Kabuki mask attacked him with tiny robots' indicates that the police officer doesn't even remotely believe him, which is a pretty common scenario for movies where weird things happen in a metropolitan setting. But that scene doesn't really make any sense in this movie. Hiro made the microbots and showcased them at an extremely important event journalists were shown attending and taking notes at, an event cut short by a suspicious fire that killed two people (one of whom was hugely influential), in a universe where robots and strange mechanics are the rule and Stan Lee was a real costumed superhero. None of his story was unbelievable at all.
327** It's possible, but it should be taken into account a few things: one is that this police officer is a beat cop. He probably doesn't know much more about technology than the average person and would be unlikely to follow the sort of high tech news the microbots would have been. Two, the news of the new tech displayed at the show would probably have been overshadowed on the news and social media by the fire that killed not only Tadashi, but one of the most famous engineers and roboticists in the entire world. Things like the technology we saw in the movie tended to be experimental and rare. And we don't even know how long Fred's dad was a hero or if he was even widely acknowledged. Remember that in the comics and movies, not everyone believes there is a Franchise/{{Batman}} either.
328** Three, Hiro has already been established as being incredibly smart for his age - he graduated high school when he was just 13 and has already applied for college, yet still acts like an excitable, hormone-addled teenager who, according to Baymax, is only now undergoing puberty. Odds are if a normal-age college student came in to report the theft and explained the situation in a believable, comprehensible manner, the officer would've taken it more seriously.

331[[folder: Baymax's Medical Scanning Abilities]]
332* When we first meet Baymax he attempts to spray Basatracin on Hiro's arm sore. As a test, Hiro lies about being allergic to Basatracin, but Baymax's scan is so powerful he can tell that Hiro is lying and even that he has an allergy to peanuts. So how come later when Hiro tells Baymax (metaphorically) that Baymax gave him a heart attack, Baymax tries to defibrillate Hiro, instead of realizing that Hiro is lying again? Heart attacks are quite common and very dangerous. You'd think that they would've been one of the earliest medical conditions that Tadashi would've programmed Baymax to detect.
333** Well, one minor note -- Hiro didn't really lie by saying that Baymax gave him a heart attack, since it's quite a common figure of speech. Additionally, heart attacks are very serious and life-threatening issues, so with how literal-minded Baymax is, he may have thought there wasn't time to perform a full scan to see if Hiro truly suffered one, comparable to their first meeting, where Baymax had just recently scanned Hiro and would have picked his allergy up from that.
334** Nurse here. If a patient says they're having a heart attack, you do NOT go straight to defibrillation without verifying. If you did, you'd cause more deaths than you'd prevent.
335*** Then chalk it up to a very dangerous bug that Tadashi would probably have fixed if he’d had the opportunity. I don’t recall the movie saying that Baymax was fully ready to begin working before the fire.
336** Another possibility is that Baymax could easily done a near-instantaneous scan on Hiro's circulatory system but the writers chose to have him try to defibrillate Hiro because RuleOfFunny.

339[[folder: Where did Tadashi get all those medical procedures?]]
340* We know Tadashi is a robotics student, not a medical student. He did state that he programmed Baymax with over 10,000 medical procedures. Since it's much too unrealistic for him to be an expert in engineering AND physiology, where would he get all the knowledge to be able to program them into Baymax? Did he collaborate with medical students from another school?
341** The series confirms that Tadashi had the help of a biomedical student in creating Baymax.

345[[folder: Yokai using standard microbots]]
346* Callaghan was a robotics genius. It just bugs me that after getting his hands on Hiro's microbots, and with considerable time (enough to manufacture a big bunch of them), why did he NOT upgrade/improve/weaponize them in some way? He could have thought of dozens of ways to make them more versatile or with more functionalities aimed at fulfilling his goals. Moreso after first meeting the heroes.
347** Why would he need to? If what he wants is to rebuild the portal during Krei's grand opening celebration, there's no need for him to weaponize the robots when they can already basically do whatever he wants. What upgrades/improvements/weaponizations did you have in mind?
348[[/folder]]
349
350[[folder: Yokai's use of microbots]]
351* I know the real answer to this one is "they couldn't show this in a Disney movie", but why does Yokai go the complicated route of reassembling that portal to kill Krei? He thought his daughter was dead, so he obviously was willing to kill. But he could have just forced his microbots into Krei's body through the latter's orifices and ripped him apart from the inside. And that is assuming he couldn't just rip Krei's limbs and head off his body.
352** The simplest answer is that Callaghan considered his plan to be poetic justice. It was Krei's defective portal that destroyed everything Callaghan valued, so it would be that same portal that destroyed everything Krei valued. Also, we can assume that Callaghan's endgame was to toss Krei into the portal as well, meaning that he would experienced the exact same death as Callaghan's daughter. Kind of an "eye for an eye" deal.
353[[/folder]]
354
355[[folder: What's with the secrecy?]]
356* In the news broadcast at the end of the movie, the news anchor calls our heroes "unidentified individuals", and stresses how the entire city is asking who they are. Why exactly are Hiro and his friends keeping their identities secret? In fact, ''how'' are they keeping their identities secret? Aside from Fred, none of them are concealing their faces, and they must live somewhat high-profile lives as top-student prodigies at one of the most prestigious schools in the world. What's more, Callaghan and Krei know who they are and have no reason to keep their secret.
357** Science college students are ''not'' high-profile. Not remotely. Can you name or identify by sight any of the students at MIT? Football players, maybe, but if you're in the lab, nobody outside the school has any idea who you are or what your face looks like -- or, frankly, cares. Basically the only people who would recognize the group on sight are the handful of people who see them on a daily basis already.
358** Fair enough, but Hiro are the kind of people introducing the world to brand-new, revolutionary technology like micro-bots. It seems a tad improbable that no-one is going to know who they are if they mass-produce them, or make the connection when their hero work becomes publicised. This also leaves out the "why" -- why do they avoid taking credit for defeating Callaghan? So they can be superheroes? Well, ''why'' do they want to be superheroes? Their original objective was to track down Tadashi's killer, and they did. If they want to help people, it seems they'd do way more good for the world focusing on their science work, particularly if their work as superheroes actually forces them not to replicate and mass-produce their equipment as they presumably originally intended.
359** You're still really overselling how famous technology developers are. Sure, you know what UsefulNotes/SteveJobs and Bill Gates looked like. What about the guy who invented [=DVDs=]? I'm gonna guess you can't pick him out of a lineup. As for why? They're a bunch of geeks and nerds -- if there's any demographic who'd be more into becoming superheroes than that, I can't think of it.
360** 'Why are they keeping their identites secret'? Fred probably insisted, because "that's what superheroes do". As for whether anybody else will care enough to ''try'' to unmask them, well, that's more of a SequelHook than a thing you bring up in the last two minutes of the movie.
361** As for Callaghan and Krei, the former would probably be too distraught over learning his daughter was still alive to try blabbing to someone about the heroes' identities, and even then, he's also a criminal. As for Krei, does he actually know who the members of the team are? Even if he did, they could just ask that he keep their identities a secret -- having just had his life saved by them, he'd probably be happy to oblige.
362** And how many people actually saw them, anyway? Most of the people had already gone running from the ceremony by the time the team showed up to confront Callaghan -- the most anyone besides Krei would've seen was a vague view of some teenagers in costumes, atop a building, as they were hurrying in the opposite direction -- and the team seemed to have fled the area before emergency personnel showed up. All in all, Krei is the only one who could conceivably reveal their secret to the world, and not only would he have no reason to, but as mentioned above, he's already heavily indebted to them, so it's the least he can do. (I think the movie pretty heavily implies that he's something of a SecretKeeper, by the end of the film -- he's the only one who was there to tell officers the story of what had happened, and someone had to have boxed up Baymax's rocket fist and returned it to Hiro.)

364
365[[folder:...Maybe it's ''your'' fault, Callaghan...]]
366* Hear me out on this...If Callaghan somehow knew that Krei knew that the portal test was unsafe, why didn't he try telling his daughter or convincing her to back out of the project, instead of just yelling at Krei about it afterwards? Even if he didn't know at first, putting aside the question of how he figures it out after the accident, his daughter was testing out a teleportation portal. Shouldn't he have figured something might have gone wrong?
367** Grief isn't rational. Even people who know, factually and beyond doubt, that their loss was accidental and not anyone's fault will ''still'' look for someone to blame as an outlet for their emotions. Callaghan fixated on blaming Krei as an alternative to accepting her loss, because Krei was in charge of the project.
368** Stemming from this... Why didn't he just try suing Krei? If Krei knew there was something wrong with the project that he deliberately didn't tell Callaghan or his daughter about, it would seem like a pretty easy win for him, instead of trying to enact the most elaborate revenge scheme in history. He could sue the guy for everything he owns, and it would probably ruin him as much as sucking his new building into a portal, especially if it became known to the public that Krei was responsible for human life being lost inside the portal.
369*** Because he knew that Krei, as a big businessman, has an army of lawyers and even if Krei did something underhanded, he'd never be able to prove it. Also, irrational -- he might well realize on some level that Krei ''didn't'' do anything actionable. He's just angry at the one guy involved in the process that isn't him.
370*** I'd infer from the secret lab and so forth that Silent Sparrow was a super-classified project. It may not seem fair, but exposing classified information in a civil action is a felony. In other words, if Callaghan tried to sue Krei, he'd be imprisoned before he got his day in court.

377[[folder: Some friends...]]
378* I know this may sound a bit mean-spirited, but... what was up with the way the other members of the team reacted to the reveal about Callaghan? Yes, I know it was wrong for Hiro to try to use the robot his brother designed to help people as a senseless killing machine, but it was still understandable why he reacted that way, especially when he's a teenager who's just seen someone brush off the death of someone he idolized and loved. And the way they come at him afterwards seems ''way'' too angry and mean, with no compassion or sympathy for what they've just learned about the death of their friend. "How dare you get angry and upset over such a horrifying reveal about the death of your only brother! Shame on you!"
379** They're not angry at Hiro for being angry and upset. They're angry at him for trying to kill Callaghan.
380** ''Why'', though? He acted out in a fit of rage, after hearing Callaghan make a disparaging remark about Tadasi's death - it's not like Hiro decided to kill him over nothing. As Tadashi's closest friends, they could've understood this better and tried to console Hiro in a manner more efficient than just yelling at him. The way they acted in the film proper didn't even get them anywhere -- it was Baymax's recordings of Tadashi building him that did that.
381*** They may or may not have been in a bit of denial. Callaghan was their professor, too, so even if they understand Hiro, they might still be reluctant to kill a guy that they were idolizing themselves until recently.
382** Well Hiro ran off pretty quickly. They were still reeling from the reveal that Callaghan had survived, started the fire in the first place and also Hiro trying to suddenly murder him.
383** It's possible the writers had [[https://en.wikipedia.org/wiki/Three_Laws_of_Robotics the laws of robotics in mind]], all of which have to do with forbidding robots from harming human beings. Surely robotics students would be familiar with them?
384** Crazy thought here -- maybe, just maybe, a bunch of college kids and science nerds don't like the idea of killing someone and might, ''just might'' consider murdering someone in a fit of vengeful rage to be kinda sorta a bad thing. I know, wild, right?
385** Or making ''them'' all into unwitting '''accessories''' to murder a bad thing, for that matter.

387
388[[folder: Aftermath]]
389* What was Callaghan going to do if he'd succeeded in tossing Krei and his new building through that portal? Granted, he was probably so immersed in carrying out this plan that what he would be left do to afterward wouldn't have occurred to him, but after such a long time, he presumably can't show himself as Callaghan again without arousing suspicion, especially once the team finds out who he is...
390** Presumably, if Hiro and friends hadn't stumbled upon the lab, then nobody ever would have learned that Callaghan was ''even alive'' in the first place. So he wouldn't have intended on showing himself, anyway. The events of the movie did throw a wrench in that, but Callaghan probably intended on just disappearing again after getting his revenge.
391[[/folder]]
392
393[[folder: What are we waiting for? No, really.]]
394* We see Hiro and the team discover Callaghan's true motives for going after Krei in the middle of the night, but they don't try to apprehend him until the next day, after he's already pieced the portal together and started destroying Krei's new building. If Baymax's scanner was functional again and could find him, why didn't they try confronting him sooner, and elsewhere?
395** Hiro and his friends were tired. They had undergone two very physical ordeals (fighting Yokai/Callaghan and fighting Baymax in combat mode) and a big emotional upheaval (the professor they looked up to who was thought to be dead was alive and had tried to kill them multiple times). They probably decided to sleep and resolve the situation in the morning. They didn't know when Callaghan planned to attack.
396** It seems illogical to have the discovery scene end on Hiro donning his helmet and saying "What are we waiting for?" if the team's next action was to go to sleep, though, doesn't it? Also, them not knowing where Callaghan was going to strike is a bit of a moot point because of Baymax's scanner. One scan of the city would've told them at once where he was.
397*** Oops, my apologies. I read it as ''where'' Callaghan would attack, rather than when. Even despite this, however, why would Hiro say "What are we waiting for?" if they actually end up waiting for something? And the application of Baymax's scanner still applies -- they don't have to wait for him to show himself to find out where he is.
398[[/folder]]
399
400[[folder: Baymax's Medical Scanning Abilities 2]]
401* This is a couple of headscratchers, in one... First is why the team didn't think to have Baymax scan Krei himself, to see if his vitals matched those of Mr. Kabuki Mask. Second is why Baymax wouldn't have scanned Callaghan in the past, seeing as Callaghan was Tadashi's robotics professor (wasn't he?), and Baymax was Tadashi's robotics project... Wouldn't that have warranted a demonstration of Baymax's abilities to Callaghan?
402** And stemming from this, isn't Baymax's scanner in itself a massive invasion of people's privacy? Well, when Tadashi introduces him, it's implied he's only going to use it when someone requires medical attention, but then he uses it to scan Kabuki Man during the chase scene, which inspires Hiro to upgrade the scanner further, allowing Baymax to scan the entire city's population at once. Baymax can basically access anyone's medical history and then reveal it whenever and to whomever he likes, and no one even brings up the negative connotations of this?
403*** Baymax's scan only reached the entire city after Hiro modified it (it's also implied that he had access to more resources at the time due to being given access to Fred's wealth and resources). The only ones who knew about Baymax were Hiro, Tadashi (assuming Aunt Cass wasn't told) and their friends. It's not even known if Callaghan knew about Baymax. No one had the chance to study Baymax and consider the ramifications of his technology. As for Baymax scanning people without their permission that could be Baymax's default programming; when activated scan everyone he meets until someone says "I am satisfied with my care." Since Baymax's technology was a new invention (it took Tadashi ''84 tries'' to perfect Baymax) it's possible only a limited few knew about it.
404*** They could have thought up the negative connotations, except that they probably believed ScrewTheRulesImDoingWhatsRight.
405** They could have tried to scan Krei, except that would require two things: '''1)''' They have to know where Krei is. He's in meetings or not even in town all day - and he probably doesn't even ''live'' in San Fransokyo. '''2)''' They can't exactly get close to Krei on normal occasions -- especially not with Baymax in tow, and when they did get close enough to Krei to scan him, he could easily call security on them ''and'' spin them as attempting to frame him for a crime he did not commit -- and he has the money to get good enough lawyers to get away with it. It was far, ''far'' more efficient to catch him in the act.
406*** Okay, so they couldn't get close enough to scan him, but what about researching some of his medical information and comparing it to Baymax's scan?
407*** Why would they bother? Two things: 1. They're looking to find the man in the mask, and the scan will lead them right to him, ''no matter who he actually is''. Knowing 100% whether it's Krei or not is immaterial to the task of finding him. 2. Krei is their only suspect, and once they realize he's a possibility, they immediately conclude that it's definitely him. They see no need to confirm something that, to them, is the only possible answer.
408[[/folder]]
409
410[[folder: Pronunciation]]
411* Why does Honey Lemon pronounce Hiro's name differently than everyone else does? I think there's a proper term for how she does it (rolling her 'r's, I think?), but phonetically, she pronounces it like there's a "t" instead of an "r" in the middle...At first, I thought it may have been due to an accent she had, but she never says anything else like that throughout the rest of the movie, and no one else (not even Hiro's aunt or brother) addresses him like she does.
412** According to the supplementary materials, Honey Lemon is of Hispanic ancestry (as is her voice actor). Her pronunciation of Hiro's name is due to her accent.
413** The alveolar tap? She's using the original Japanese pronunciation instead of the Anglicised one. As for why the Hamadas also pronounce it as such, there can be a variety of reasons: they grew up in San Fransokyo so the English way is more natural to them, they want to show that they're Americans through and through by saying it how Americans say it, they thought sticking with the Japanese pronunciation was snobby, or just personal preference.
414[[/folder]]
415
416[[folder:Why not give everyone those weapons?]]
417* Honey Lemon's balls and Wasabi's laser blades are clearly the most effective weapons against the microbots, [=GoGo=]'s rollerblades and Fred's firebreathing don't really do that much damage to them. Since Hiro designed the microbots, this should be obvious to him, so why don't they arm everyone with those blades and/or balls? This is especially baffling with Hiro, since his armor doesn't appear to have any weapons at all, so he's totally dependent on Baymax -- but what if the two get separated? Having a more versatile power set makes sense if the Big Hero 6 were planning on becoming a general superhero team that goes against different kinds of villains... But at this point there's no such plan, their one and only mission is to defeat Yokai and the microbots. Obviously the [[WatsonianVersusDoylist Doylist]] answer to this question is that they wanted each character to have a unique look and powers, but there doesn't seem to be any in-universe explanation for it?
418** 1. They weren't given weapons just to fight the microbots. They were given weapons to fight the villain -- and Gogo proves she's pretty good at that with her tech. 2. Each person's gear was based on the project and tech they were already working on.
419*** 1. The villain is clearly just one man, and it's never implied anyone has actual superpowers in this setting, so once the microbots are taken care of, defeating Yokai shouldn't be a big problem to the six of them. The microbots should really be the only threat they need to focus on. 2. Even though that's true, their explicit goal is to defeat the villain, not to showcase their technology. Shouldn't they try to reach that goal as efficiently as possible, not to flash off their pet projects?
420** Fred is the only one who's at a significant disadvantage against the microbots, since his flamethrower doesn't appear to do much to them on its own. Honey is the only one who knows the formulas required to create those little orbs, and Hiro trusts Baymax enough to know that he'll be there when he needs him -- I can't think of much that would be able to separate them ''and'' keep them apart from each other effectively.
421*** Why can't Fred and Hiro have those blades as well? Even if Hiro trusts Baymax, why couldn't he have them as a failsafe, just in case everything else goes wrong? And shouldn't Hiro know that the flamethrower is useless against the microbots, so why was Fred given that to begin with? As for the balls, the process of creating them doesn't seem to be ''that'' complex, so there's no reason why Honey couldn't have taught that to the others.
422*** 1.) Hiro wants to see his brother's invention used for the greater good, albeit not in the way Tadashi intended, and is the only one who can control Baymax's combat programming. Baymax has resigned himself to ensuring Hiro's physical and emotional health and satisfaction. So the two are essentially meant for each other. 2.) Fred was the one who wanted to use science to become a mutant, fire-breathing lizard. He still has his super-jump, which is useful for an evasion tactic, and the bots may not be able to handle high temperatures shooting at them for a long period of time. 3.) Hiro didn't even consider taking out the microbots as a priority until the final encounter with Yokai; before then, it was always "Get the mask, get the mask, get the mask!" 4.) It looks like Honey had the entire periodic table on that little purse of hers, which she used to punch in the formulas to achieve different results and reactions when she throws the balls. ''I'' wouldn't trust anyone else with a weapon like that unless they had a significant understanding of chemistry.
423*** In addition to Honey Lemon's knowledge of chemistry, Wasabi is proficient in martial arts, making him the best suited to the laser blades (while Gogo is athletic, being a skilled cyclist and adrenaline junkie, it is unknown if she's proficient in martial arts).
424*** Though, if they'd had time, integrating the plasma lasers into the wheels on Gogo's suit could have been a big asset (using the wheels to act as something like a rotary cutter when activated)
425[[/folder]]
426
427[[folder: Pacifist programming, huh?]]
428* If the team makes it a point to not actually hurt Callaghan if they can avoid it, what was Fred thinking shooting at him with a ''flamethrower'' during the final confrontation? Callaghan would've been roasted if he hadn't shielded it with the bots.
429** Those aren't really comparable. When Hiro threatened to kill him, he had already been beaten and was helpless. Hiro would've essentially murdered someone in cold blood. But killing someone in the heat of the battle while trying to save lives is not really the same. If a cop kills someone who is shooting at him and at innocent bystanders, it's a whole different thing than if he kills someone who is helpless and has surrendered.
430** Fred's flamethrower spouts actual flames, not a clinging incendiary in the style of military flamethrowers. And Yokai ''does'' have full body coverage: catching his costume on fire would, if anything, encourage the villain to take off the mask ''himself.''
431[[/folder]]
432
433[[folder: Hiro's suit 2]]
434* Is it me, or are Hiro's ankles not covered or protected by his suit? And if they really aren't, then why? Fred clearly has the resources to fix this, and wouldn't leaving ''any'' part of his body exposed be a danger to him in battle? It seems like a pretty big oversight.
435** Ankles are the third most awkward part of the body to encase in rigid armor. Hiro also needs full flexibility to hop on and off Baymax so easily.
436** His suit fully covers his body including his ankles in the TV series.
437*** Which could indicate that the V1 suit was something of a rush job and simply modified out of civilian clothes that he grabbed.
438[[/folder]]
439
440[[folder: Portal debris]]
441* Did anyone else notice that at least some of the debris Hiro and Baymax encounter inside the portal appears too large to have fit through it in the first place? During the fight with Callaghan, most of what's getting pulled in looks to be about Hiro's size or slightly larger, yet at one point while inside it, we see Hiro running the length of a huge and intact fragment of a window, and the debris that destroys Baymax's suit has a very questionably large size, too.
442** The portal used in the test run is probably the final, more compact version. Earlier prototypes maybe big enough to pull those larger debris. Alternatively, since the technology clearly utilizes {{Hammerspace}}, the large debris may have come from other people's experiments.

444
445[[folder: How old are they?]]
446* This has bugged me for a while. I know Hiro is 14 because it's mentioned, but I can't find any solid material on how old the other guys are. They've all clearly been working at SFIT for some time on their projects, and they're all older than Hiro, but there's nothing in their design or dialogue that pins their ages down, and I can't seem to find anything canon.

448
449[[folder: Walking off the pier]]
450* Minor squabble, but when Baymax stops Hiro from walking off of the pier, he tells him, "Always wait one hour after eating before swimming." Given that this was the first thing he says after saving him, does that mean he would've let Hiro fall into the water if he hadn't eaten anything in the last hour? Isn't it a little weird for a healthcare robot to be programmed that way?

454[[folder: How would a successful teleportation demo have worked?]]
455* In watching the teleportation demo disaster, I'm wondering how the logistics of a successful demo was supposed to have worked. First off, we're shown that simply tossing a hat into the portal had enough momentum to carry through to the other portal and emerge with its velocity intact. Yet when it came time for the pod it is flung into the portal at a pretty fair clip...20mph? 30mph? Why did the pod need to enter so fast? Then, what was the exit strategy? The pod was guided on a track straight to the entrance of the first portal. But the second portal, had....well nothing. No landing track, no netting, not even a stack of mattresses to facilitate re-entry. Was it just going to crash onto the ground below? If the pod was capable of some kind of thrustered flight, then the pilot would have needed to fire their braking thrusters immediately upon exiting the portal to prevent it from crashing into the control room which it was now heading toward. And if the pod was capable of flight it seems like the demo would have worked better to hover the pod at the first portal, gently enter and emerge from the second portal and land.
456** There's an unidentified framework on the ground behind the scientist who catches the hat, it looks like a catch net similar to those used to stop fighter jet momentum when they land on their aircraft carrier. So odds are the machine would have unfolded, spread the net and caught the pod as it exited if the test had been successful.

459[[folder: After-hours college]]
460* Wow, that college sure is busy after hours when Hiro gets shown around! None of the team are out doing at-home stuff.
461** Anyone who's worked with or known the type of super students the [=BH6=] are knows that this is not unusual.
462** Super students aside, most college labs are active at night, since most students have a day job to put themselves through college and do most of their work in the evenings.

466[[folder:Interfering with the microbots]]
467
468* Hiro knows how the microbots work better than anyone, but he doesn't even consider building a device to interfere with or override Yokai's control of them.
469** Hiro is too fixated on his revenge on Yokai, and can't see past it to get the idea of tackling Yokai's control of the microbots instead of getting at Yokai himself.
470*** Besides, who knows how long it took Hiro to build that transmitter.
471*** Additionally, given the fields he exhibited for the microbots such as construction and transportation, Hiro likely programmed the transmitter with a very powerful signal to prevent interference or disruption as a safety measure. It wouldn't do for some unforeseen event disrupting that transmitter's signal if the bots were being used to build a structure. Everything would collapse immediately and someone could get hurt.
472*** Yokai, being a brilliant scientist as well, likely built extensive safeguards into his controller to prevent such an override from occurring.

475
476[[folder:Multitasking]]
477
478* At the climax battle, Yokai somehow manages to focus his thoughts on making the microbots do seven (and rather huge) different tasks simultaneously: piecing together the portal as well as attacking each individual [=BH6=] member in different ways. The guy must surely be the king of multitasking.
479** He's a genius who teaches geniuses and has a will powered by revenge. Not unlikely.
480** Also, if you pay attention to how he attacks, you'll notice he focuses on one member at a time. Once he has them contained, the bots then just slowly close in on them and Yokai switches focus. He grabs Fred's limbs and starts stretching him, he encases [=GoGo=] in a ball, he sandwiches Wasabi between two building panels, and buries Baymax under the bots (and Hiro not only can't do anything without Baymax, but he was dealing with the "reverse gravity" from the portal). All of this, while focused on trying to skewer Honey. Having the bots do a big task is one thing... having them do several large tasks, slowly and steadily without interruption is still somewhat hard, but certainly easier than doing all of it at-once. It's once each of [=BH6=] breaks out of their containers that the situation starts falling apart for Yokai.

484[[folder:Neural interface]]
485
486* The thought-controlled interface for the microbots, which is glossed over to an absurd degree if you understand anything about the engineering challenges involved. That the neural interface works so smoothly is considerably more impressive and with far wider applications than the microbots themselves, but nobody even remarks on it.
487** It's probable that Hiro simply adapted a pre-existing neural interface technology to the microbots, given that no one is especially impressed by it.

491[[folder:Raw materials]]
492
493* Where did Yokai get the raw materials to mass-produce hundreds of millions, if not billions, of small electronics? And where does he keep them? How can he sneak up on people with a swarm of billions of robots following him around?
494** It's implied that Krei's abandoned island-lab is being used as his base of operations until his scheme is ready to be implemented. And most of his sneaking around is done during the night and is implied to be done through areas like docks and industrial areas which are pretty much ghost-towns at night. Though how they were able to have a car chase through such a bustling city -- even in the dead of night -- without any members of the public seeing it remains a mystery.
495** You can ask this same question for Hiro. They're a material that's super cheap that costs next to nothing or are completely free in a place somewhere. Just 3D=print them and boom, you're done.

499[[folder:Battery]]
500
501* Baymax's battery runs low after a few hours of adventuring. What kind of battery did he get to let him fly for hours, use weapons, etc without considerably adding to his bulk?
502** This actually is touched on when Hiro initially meets Baymax. While Hiro is examining his older brother's robot for the first time he comments and tests Baymax's knowledge while asking Tadashi a series of questions as well. The only concern that remains unanswered by Tadashi is a suggestion that Hiro puts forth about the battery.
503--->'''Hiro:''' Hey, what kind of battery does it use?
504--->'''Tadashi:''' Lithium ion.
505--->'''Hiro:''' You know, super-capacitors would charge way faster.
506--->'''Tadashi:''' Huh.
507** Given that Hiro was able to put forth a suggestion within a few moments of analyzing the robot, it is hardly inconceivable that he was able to upgrade the battery. That and it is definitely possible that the armor had its own power source that linked with Baymax, much like how the sensors worked with and boosted the robot's initial scanning capabilities.
508** The thing is, while Hiro was right that [[ShownTheirWork super-capacitors would charge much faster than lithium-ion batteries]], they would also ''discharge'' faster. It's possible that while Hiro was working on the microbots, Tadashi took Hiro's advice and swapped out Baymax's batteries for super-capacitors, not knowing that Baymax would need long-term power as well as short-term when Hiro accidentally sent him after Yokai's factory. And when Hiro finally upgraded Baymax into a fighting robot, he ''put back'' the Li-ion batteries as a secondary power source.
509*** Or Hiro never swapped the Lithium Ion batteries, and instead improved them for better efficiency and charge time. After all, the supercapacitors were being floated when Baymax was still meant purely as a medical bot (in which case, the faster discharge rate would be negligible, as the unit probably wouldn't need to be active for prolonged periods of time, or could be cycled with others if it was).

513[[folder:Skeleton]]
514
515* How can Baymax deflate and "wrap" himself up to such a tiny space with that carbon-fiber skeleton inside?
516** The simplest answer is that it's built to be collapsible.
517
518[[/folder]]
519
520[[folder:Too big]]
521
522* Baymax is huge and cuddly. But he's hardly suited for performing surgery. He's kind of like a "First Response" guy that would be great to help injured people until they get to a hospital. HE EVEN FITS INTO A BRIEFCASE. So he'd be used in ambulances to assist a paramedic so that you only needed the one and a driver, and sold to construction companies to be on the scene. Because he's big, he'd be good for crowd control. So he really WOULD help a lot of people. He's just not suited specifically for hospital use.
523** He might not be able to work trauma or surgical units, but he could be a big help on the hospital floors, where he can monitor patients' vital signs and determine/dispense medicine or call for a consult if human help is needed. By the same token, he'd be great for working in nursing or rehabilitation centers, where he could serve much the same function.
524** All that aside, it seems like the true breakthrough is the instant-diagnosis EverythingSensor medical scanner. Stick one of those in every hospital bed, exam room, and triage center in the country and everyone's job suddenly gets a lot easier, balloon robot or no.
525** He introduces himself as a ''personal'' health care companion, so surgery and other complex procedures aren't in the programming anyway. Tadashi intended for people to have a Baymax in their home so that they could consult him first before spending money on a clinic or ER visit.
526** It's also possible that later versions of Baymax would utilize either segmented air chambers (so the hands/arms could deflate down to the basic skeleton for more delicate work), or would be modular and designed for specialized tasks (the Baymax we see being a general health model or primary caregiver, with other chassis fitting specialized designs for other work (multiple slimmer limbs for a surgeon, enlarged optical systems for things like a mobile X-ray, etc)

529[[folder:Hypersleep]]
530
531* The Teleportation Pod Callaghan's daughter is in having a hypersleep function seems kind of weird, don't you think, given that it was only required to go about two feet? But then you get to pondering about how the portals were prototypes for a transportation system, so obviously they'd need a prototype vehicle, too. And such a vehicle would need to be equipped with a hypersleep function in the event of an emergency, regardless of trip length.
532** Sounds like you answered your own question -- the hypersleep was probably put in as a failsafe in the event of an emergency, that would keep the passenger alive until a rescue mission could be mounted. Which means Krei ''didn't'' cut corners like Callaghan said he had, since everything was within the normal parameters and they had the necessary failsafes in place. The only issue was that the project was shut down immediately after the accident, before any attempt at a rescue could be made. (If anything, this begs the question of why the government-dude never considered a rescue.)

536[[folder:Bot fighting being illegal]]
537
538* Why? I can't think of a reason why it should be.
539** Hiro does point out that the sport itself isn't illegal, just making bets on it. No idea why that is, though.
540** Well, it probably classes as unregulated gambling.
541*** And Hiro is underage so even if making bets on bot fighting was legal he’d still be in trouble.
542[[/folder]]
543[[folder: Escaping the portal]]
544* You would think that a boy genius like Hiro would be familiar with Newton's Laws of Motion -- an object in motion will remain in motion unless acted upon by an opposing force, for every action there is an equal and opposite reaction, the total of forces on an object equal the object's mass multiplied by the vector sum of the accelerations applied. In the frictionless, gravity-less, wind-less environment of the wormhole void, all they would need to do get back through the portal would be to apply a force towards the portal. Since Baymax is basically a balloon (ie. gas under pressure, retained by an elastically flexible container), and Disney have already shown us that they don't mind making an extended fart gag, why not have Hiro rip a hole in Baymax's backside? The exiting gas would have applied force towards the portal, and all three of them would have floated safely through. If that wasn't fast enough, Baymax has two hands -- he could position his body such that his shoulders were pushing the pod, detach the rocket fist and give it to Hiro, who would hold onto it with the electromagnets in his suit, then Baymax could grab Hiro with his remaining hand, and remotely activate the rockets; such a solution would in fact be more controllable than the free-flying rocket fist, as Hiro would be able to change the angle of the exhaust if necessary, negating the need for Baymax to line up a perfect shot.
545** Because none of those plans would've been fast enough. (Also because it's never shown in the movie that the rocket fists can be activated remotely.) Even with the plan they went with, the portal explodes mere ''seconds'' after the pod emerges safely from it. Trying to implement any other option would run the risk of killing Hiro and Abigail for the sake of trying to save a robot who's expendable and can be rebuilt. Baymax was programmed to ensure the health and safety of his patients above all else -- he's not going to attempt, suggest, or allow for a course of action that puts them in significant danger just to save himself.

548[[folder:Wasabi's death machine]]
549
550* When Hiro meets Wasabi in the nerd lab, he nearly walks into Wasabi's laser-cutter device and Wasabi pushes him behind the stripey warning line. Then Wasabi demonstrates the power of the thing by tossing an apple through it and showing how it gets instantly chopped into paper-thin slices. Forget all the other adventures; Hiro never came closer to a hideous gruesome death than he did just before Wasabi stopped him from walking through the lasers of slicey doom. How is it that the incredibly OCD Wasabi never put up anything more than a line on the floor to warn people of his death device, or that not one other labmate, professor, advisor, or pointy-headed university bureaucrat insisted on some kind of actual precaution?
551** Not the most ideal answer, but maybe he only had the machine on for a second while he was working on it, and he’s careful to switch it off when he’s not there to warn people? Granted, it’s still really dangerous to have that setup even for a second, not to mention out of character for the uber-careful and precautionary Wasabi.
