Baymax

Background

Baymax came into being when Tadashi Hamada had finally calibrated his creation to be properly functional. Eager to show his success, Tadashi then brought Hiro Hamada to the San Fransokyo Institute of Technology one night so he could meet Baymax. Using duct tape, Tadashi purposely causes Hiro physical pain on his right arm, making Hiro yelp in pain. The sound activates Baymax's pack, and Baymax inflates out in front of Hiro, prompting Tadshi to introduce Baymax as his latest project. Baymax explains his background to Hiro, and then analyzes Hiro and gives him a brief diagnosis, tends to his wound and gives him a lollipop for being a good patient. Baymax tells Hiro the code words meant to deactivate him ("I am satisfied with my care") and after Hiro says those words, the robot returns to his pack.

Sometime after Baymax was introduced to Hiro, the robot was somehow transferred to the Hamada residence, remaining inactive in his pack. During Baymax's inactivity, Tadashi was tragically killed in a fire at the university, making Hiro grieve for his brother's death. Following these events, a depressed Hiro accidentally stubs his toe, letting out a cry of pain which summons Baymax, who greets Hiro and tries to tend to his wounds even diagonsing Hiro to have hit puberty.

Though surprised that Baymax was reactivated, Hiro instead tries to get rid of Baymax, finding him to be an unnecessary distraction. While Hiro tries to push Baymax back into his case, he slips and falls onto the floor. At this angle, Hiro notices a Microbot, one of the many that Hiro had presented at the university (the night of Tadashi's death). Confused as to why one would still be active when the Microbots were supposedly destroyed in the fire, Hiro sees the Microbot trying to link itself with other Microbots, but believing no other Microbots to be present, Hiro deems the device defective and discards it. Baymax, however, notices the bot's movement and picks it up. He tells Hiro, "Your tiny robot is trying to go somewhere." Hiro sarcastically orders Baymax to find the Microbot's desired location; however, Baymax takes Hiro's order literally and leaves to follow the Microbot's trail, causing Hiro to frantically catch up with Baymax.

Eventually, Baymax tracks the destination down to an old warehouse. Hiro finds a way in through the second-story window, but Baymax gets caught due to his girth, so he deflates and then reflates to get in and the two then explore the warehouse. As the two find out that someone has been producing excessive quantities of Microbots, a masked man by the name of Yokai suddenly confronts Hiro and attacks him with the Microbots. The chase is hindered by Baymax's slow movement and size once again, but ultimately, he is pushed out of the window by the Microbots and cushions Hiro from the high fall. Hiro immediately tries to notify the San Fransokyo Police Department to report the incident, but the police officer is unconvinced by Hiro's frantic claims. Before Baymax can contribute to Hiro's story, he suddenly becomes impaired due to his power running low. With few options to turn to, Hiro is forced to take Baymax home to recharge him.

Once he regains cognition, Baymax notices and questions Tadashi's absence in the Hamada household. Hiro explains Tadashi's death, leaving him with a heavy heart. Sensing Hiro's condition, Baymax downloads files on personal loss from Hiro's computer in order to comfort Hiro and, acting on his new knowledge, calls Hiro's closest friends despite Hiro's protests. He then gives Hiro as further treatment involving "compassion and physical reassurance."

Hiro thanks Baymax seeing how helpful it actually is. Baymax then tells Hiro, "I am sorry about the fire." Hiro tells him it was an accident. At that moment, Hiro realizes that the fire that killed Tadashi was not an accident, but a way for Yokai to obtain his Microbots and cover his tracks. To avenge Tadashi, Hiro decides to bring Yokai to justice with Baymax's assistance. Setting to work on his plan, Hiro downloads files on recorded karate and martial arts moves to create a special chip for Baymax to give him the ability to battle. Hiro also creates a special suit to protect Baymax and execute his strength, though Baymax notes his discomfort, feeling that the modifications may undermine his intentional purposes.

Nevertheless, Hiro assures the best, and instructs Baymax to do some karate moves. After Baymax's training, the duo then sneaks out into the night to track down Yokai. However, Yokai is nowhere to be found at the warehouse; Hiro is prompted to use the remaining Microbot to track the others, which soon leads them to the nearby docks, where Yokai is on the prowl. Hidden from Yokai's sight, Hiro and Baymax are about to battle; suddenly, Hiro's friends Go Go Tomago, Wasabi, Honey Lemon, and Fred arrive and catch them on the scene since Baymax had contacted them earlier. Before the group can process what is going on, Yokai is alerted by their presence and immediately confronts the group, throwing a cargo load towards them only to be foiled by Baymax protecting the team. While the group retreat to Wasabi's van to get away, Baymax stays behind to try holding the villain off; however, his efforts are for naught as Yokai sends Baymax skyward with a Microbot throw, making Baymax crash on the roof of Wasabi's van. With Yokai on their trail, the team find themselves in a car chase through San Fransokyo streets. During the chase, Hiro nearly falls out of the van, but Baymax saves Hiro and fastens his seat belt for Hiro's caution. Eventually, the team escapes Yokai by accidentally driving off the docks and falling into the water, tricking Yokai into believing they have perished.

Though they have successfully escaped Yokai, the team is at risk of drowning. Removing his armor, Baymax is able to carry them up to the surface. To recover, Fred decides to take everyone to his mansion for safety; on the way in Baymax also meets and fist-bumps the butler Heathcliff. Inside, as Baymax activates his warming system for the team to rest with, Hiro ponders on Yokai's true identity. Baymax then reveals that he had scanned Yokai's health during the chase (while explaining this was because he was meant to care for everyone), giving Hiro the means the track Yokai down. However, knowing that Yokai will not be easy to take down alone, Hiro, Baymax, and the rest of the team decide to use their talents to upgrade themselves into a group of superheroes. For his upgrade, Hiro develops a second armor for Baymax that allows him to fly. With Hiro, Baymax takes a test flight throughout the city to test his capabilities. After the flight is successful, the two begin to bond as Baymax scans Hiro again and is delighted to see that Hiro's levels of happiness and serenity have increased. With this, Baymax concludes that his treatment has reached completion, and asks Hiro if he's satisfied with his care, which would result in the robot's deactivation. Not wanting Baymax to depart yet, and needing him to stop to Yokai, Hiro denies the request and commands Baymax to scan the city to find Yokai. Baymax complies, and he traces the masked villain's whereabouts are traced to Akuma Island so the heroes gather to travel forth.

At the island, they discover an abandoned portal testing facility once own by the entrepreneur Alistair Krei, leading the group to believe that Krei is the culprit behind Yokai's mask and wishes to rebuild the portal for his own purposes. Just then, the group is encountered by Yokai. While Baymax is trapped underneath rubble, he eventually joins the fight and the group defeat the villain, who is soon revealed to be Professor Callaghan, the former professor at SFIT who was believed to have been killed in the very fire that killed Tadashi. Enraged that Tadashi's sacrifice was for nothing, Hiro orders Baymax to destroy Callaghan. Baymax objects, stating that it is against his programming to harm a human being. Without second thought, Hiro removes Baymax's healthcare and leaving the fighting chip at full operation, turning Baymax into a merciless killing machine. Carrying out Hiro's order, Baymax goes after a frightful Callaghan while the other members of the Big Hero 6 try to stop their lost friend from carrying out the deed. The distraction is enough to let Callaghan escape, but Honey manages to return Baymax's healthcare chip to the robot, restoring his personality. Aware and shocked by the harm he has caused, "My healthcare protocol has been violated," Baymax apologizes to the team, "I regret any distress I may have caused." but Hiro orders him to find Callaghan in hopes of finishing the job. Baymax denies because his scanner has been corrupted, motivating a furious Hiro to ride Baymax back to San Fransokyo and abandoning the rest of the team.

Back home, Hiro tries to remove Baymax's healthcare chip permanently, but the robot refuses to open his access port as he reminds Hiro that removing his chip would only repeat the events from last time and thus would not help ease Hiro's pain. Baymax then asks Hiro if this is what Tadashi would have wanted, causing Hiro, out of grief and anger, to finally break down over Tadashi's death. Seeing Hiro's despair, Baymax comforts the boy by showing him footage of Tadashi when the former was building Baymax. The sight and sound of a comforting, loving Tadashi eases Hiro's heavy heart and bringing him to his senses. Hiro thanks Baymax for helping him, when at that moment the rest of the team arrives (having gotten off the island with help from Heathcliff) so Hiro apologizes to them for how he acted. Accepting his apology, the team then show the duo the rest of the footage they uncovered.

Watching the footage again reveals that the pilot that was in the portal test was Callaghan's daughter Abigail, and that she was apparently killed in the accident that resulted in the closure of Krei's facility, leading the team to realize Callaghan's scheme is a revenge plot against Krei, "This is a revenge story." Together this time, the team head to Krei Tech to stop Callaghan from carrying out his plan. There, Callaghan has attacked Krei and reconstructs the portal above Krei's company so that it would destroy all that Krei loves by sending it all into the portal that took Abigail. Baymax and the others confront and battle Callaghan but are soon pinned down by the overwhelming swarm of Microbots. As Baymax nearly meets his end, the robot spots Hiro seconds away from being sucked into the portal. Motivated, Baymax gathers his strength and immediately rushes to the rescue, saving the boy in time. From there, Hiro instructs the others to attack the Microbots directly to send them into the sucking portal, thus rendering Callaghan impotent. With Hiro, Baymax contributes in the Microbot's destruction and flies up to Callaghan, seemingly preparing to eradicate the villain. However, Baymax stop inches short of attacking him as Hiro has decided to follow the moral code set by Baymax, "Our programming prevents us from injuring a human being." Instead, Baymax takes off his mask and destroys it.

With the portal and the Microbots subdued, Hiro and the team prepare to escape the portal's oncoming destruction. However, Baymax does not budge as he is detecting life signals coming from the portal, "The life signs are female. She appears to be in hyper sleep." Realizing that it must be Abigail, Hiro volunteers to go with Baymax into the portal and rescue her. As the portal continues to near destruction, the two enter the portal and find themselves inside a mysterious void. After flying across for some time, they finally discover Abigail's shuttle with Baymax's scanners, finding her resting in hyper-sleep.

Using his thrusters Baymax helps push the shuttle back to the portal. As the trio make their escape however, a piece of debris collides with the trio, destroying most of Baymax's armor as well as reducing their chance of escape. However, with one rocket-fist intact, Baymax informs Hiro that he can propel him and Abigail to the portal, knowing that this means he must stay behind to save them and thus requests Hiro to state that he's satisfied with his care, as deactivation is the only way he will be able to leave the boy's side. Hiro is initially against the idea, not wanting to lose Baymax as well, but the robot calmly tells Hiro that it is the only chance they have and that, no matter what, he will always be with him. In tears, Hiro embraces Baymax and sadly recites the statement to initiate Baymax's deactivation. With these words, Baymax launches his rocket fist, sending Hiro and Abigail back to safety while he is left stranded as the portal then explodes, thus trapping the robot inside the void.

Thanks to Baymax's sacrifice, Abigail is returned, and Callaghan is brought to justice, but Hiro and the team mourn the loss of their robotic companion.

Over time, Hiro recovers from the loss of Tadashi and Baymax, finding comfort in his family and friends. Hiro officially joins the SFIT as a student and after a tour from his friends, he goes inside Tadashi's old lab. There, he finds Baymax's blueprints drawn in a notebook. He then brings out the remaining memento of Baymax: his armor fist. Upon uncovering it, Hiro notices Baymax's healthcare chip within the palm of the robotic fist. Overjoyed, Hiro sets to rebuild Baymax's body, using the chip to restore his personality and memories, only to be interrupted by Professor Granville, who tells him he has to earn the lab first. Still, Hiro continues his work between and after classes, while the rest of his friends discuss about continuing their lives as superheroes. Finally, Hiro finishes the exo-skeleton and uploads Baymax's consciousness to a computer. Baymax however tells Hiro to test the body before since it took Tadashi many tries before it was fully functional. Hiro however was too confident in himself and turned the body on, but it then went haywire and ran away.

Hiro followed the body outside the SFIT and noticed it ended up in hands of Yama, a criminal which Hiro had previously defeated in a bot-fight and got jailed. Yama remembered this and out of revenge decided to keep the robot, but once he noticed Hiro was an SFIT student, decided to make a deal as his boss tasked him with getting an item from the institute. With the help of Fred, Hiro obtained the item and took it to Yama, but Yama betrayed them and locked both up. Meanwhile, Go Go, Honey Lemon and Wasabi went in Tadashi's lab to invite Hiro to Noodle Burger, but noticed his absence. Baymax's consciousness told them that Hiro and Fred had gone to Yama's hideout, so the trio geared up to save them. After returning, Hiro explains all that happened and returns the stolen item to Granville's desk. The following day, he finally activates Baymax. Once rebooted, Baymax happily greets Hiro, following with the two sharing an emotional reunion. However, unknown to them, Yama duplicated Baymax's exo-skeleton and created an army of evil Baymaxes with it.

Baymax and Hiro then go to Lucky Cat Café, where Cass is happy to see Baymax and hugs him, then Baymax helps to carry many dirty dishes. Following this, Hiro creates a new superhero chip for Baymax which would bring back his fighting abilities, but would also give him a sense of heroism thus prevent another incident of Baymax trying to damage people. Fred also tells them that he had discussed their team's name and thought "Big Hero 6" was the best, even though the rest of their teammates had decided not to continue being superheroes. Soon, Granville entered the lab and discovered Hiro, Baymax and Fred, so Granville told Hiro that he would have to either focus on being a student or continue Fred's path.

Hiro then believed Granville was right and ultimately decided to continue his studies. Still, Fred tried to convince him in different occasions, but Hiro simply ignored him. One night, Yama's Baymax clones went out and started attacking the city to cause a distraction so that Yama could personally go to the SFIT and take the item once again. Hiro and their friends saw themselves with no choice but to suit up again since the police couldn't defeat the robots, although Hiro had to go with Baymax back to the Institute to create a new suit of armor for Baymax. There, they found out that Yama was trying to find the item again, and the two were spotted by one of Baymax's clones which ripped Baymax's vinyl. Though Hiro looked concerned, he quickly realized that Baymax could blend with the rest of the robots and acquire the item first.

After obtaining it, Yama hit his head with a book and triggered Baymax's healthcare function, so Yama discovered Hiro's plan and made the clones attack the real Baymax. The item that Yama wanted broke when Hiro tried taking it, and attached itself to the clone, overcharging it and throwing Baymax out of a window. Yama escaped while Hiro tried to hold onto Baymax, but he fell, albeit the team had defeated all the robots so they got to the SFIT in time and saved Baymax from the fall. Soon, Hiro fixed Baymax and finished his armor, then rushed to stop Yama. They then saw that the item had over-charged a train that Cass was riding, so Hiro devised a plan to stop it. After succeeding, Hiro used his gloves' magnets to destroy the item once and for all, then the team went back to the ground, now deciding to dedicate their days protecting San Fransokyo as the "Big Hero 6", in honor of Tadashi's dream of wanting to help people.

Note: This analysis goes over Baymax from the movie, the TV series, comics (NOT THE MARVEL COMICS VERSION, FOR GOOD AND OBVIOUS REASONS), even the manga and Kingdom Hearts crossover.

Powers & Abilities

• Robot Physiology: Baymax is a robot designed for care and support, as such he has abilities suited for his function.
  • Multilingualism: Baymax is programmed to speak primarily English, but it has been shown that his language settings can be changed and can talk in several other languages.
  • Superhuman Strength: According to Tadashi, Baymax was mechanically provided with considerably impressive strength and is supposedly able to lift 1,000 pounds. However, this cannot be applied to physical force due to his slow movements and vinyl padding since he was unable to even kick down a door. However, clones of him could do it since they moved faster than Baymax and had no vinyl on them. His strength is increased with his super-suit on. Moreover, the strength-application programming encrypted into Baymax permits proper calculation when actually implementing the technology-based strength in question, enabling an armored Baymax to lift up heavy girders and yet still be gentle enough to harmlessly pat a person in the back, in armor or otherwise.
  • Data Storage: Baymax has the ability to store a massive amount of data, making him highly intelligent in several fields, should he take the time to access the information from a module.
  • Medical Knowledge: Baymax has a wide database on health and has information on over 10,000 different medical procedures, including surgical, as confirmed when Baymax once produced a retractable and built-in scalpel from one of his fingers after mistaking a brokenhearted Fred for needing an actual surgical cardiac procedure. It also includes psychological health, as he tried to do therapy with Hiro.
  • Display Screen: He can project different kinds of data on the frontal torso area of his vinyl body, from analyses to images.
  • Scanner: Baymax has a built-in scanner that allows him to scan all medical data on his patient and readily identify them. With his suit, the scanner becomes enhanced and can be used to track the person down by their medical profile. In the film, this was seen powerful enough to even discern details of a person in stasis and literally trapped in a spatial void.
    • X-Ray Vision: His scanning abilities also include X-ray vision. This allows him to detect fractures and can send the diagnosed images to other devices like cell phones.
  • Defibrillators: One of his medical components, Baymax has defibrillators built into his hands.
  • Anti-Bacterial Spray: Baymax dispenses a spray from his hands to kill pathogenic microbes on his patient.
  • Heating System: Baymax's body is equipped with a heating system that warms anyone lying on him.
  • Cooling System: Much like his heating system, Baymax can make his vinyl to become cold thanks to ammonium chloride cold packs he is equipped with, so he uses this to cool down things or to apply in burns and bruises.
  • Chip Reading: Baymax's programming can be modified depending on the chip that's installed. He was able to learn karate techniques when Hiro downloaded these into a chip for him; however his personality resides in his original chip, so if this chip is removed, the remaining chips will override his initial programming.
    • Martial Arts: Due to the fighting chip installed, Baymax can execute various fighting moves and actions.
    • Sense of Heroism: Hiro created a new chip for Baymax similar to his fighting chip, but this one no longer risks him turning violent and allows him to defend innocents and other heroic deeds.
    • Dancing Capabilities: Due to the dance chip installed, he can execute various dance moves of different dance styles.
  • Audio Recorder & Player: He can record audio such as people's voices and play it from his own body.
  • Extinguisher: Baymax has a retractable extinguisher in his index finger.
  • Telephone: Baymax has been shown capable of receiving voice calls from Hiro's acquaintances, as well as video-calls.
  • Flashlight: His hands can also become flashlights to light the way in dark places.
  • Lie Detector: He can also scan people's eyes and heartbeat in order to detect when someone is lying. Hiro also created a chip to enhance this ability.
  • Scalpel: Baymax has a scalpel hidden in one of his index fingers, although he had to download information about surgical procedures before trying to use it for the first time.
  • Expanding Neck: Although not a particularly useful feature and rarely seen, Baymax can extended his neck.
• Armor:
  • Flight: Due to the thrusters on the armor's feet, Baymax is capable of flight. Despite his size, he is extremely good at maneuvering through the air. Occasionally, because of this ability, Baymax's teammates will use him as transportation. When in the air, the suit lets him reach mach speeds.
  • Rocket Fist: Baymax's armor's glove can disconnect from the suit and propel itself toward a target. This allows the glove to be used as a projectile.
  • Magnetism: The back of Baymax's armor is equipped with magnetic extensions, allowing Hiro to safely ride atop the robot's back (when wearing his own armor) without the fear of falling.
  • Overdrive Mode: With a special chip, Baymax can adapt his armor into a larger, more powerful version of himself along with a sword made out of his wings. This transformation only lasts a few minutes due to how much power it uses however, leaving Baymax in low battery mode afterwards. This mode can also be used with other armors and enhance the respective armor's abilities.

Equipment

• Chips:
  • Healthcare: The original chip, a healthcare chip, was created by Tadashi Hamada in order to house Baymax's personality, memories, and needs to make him the ideal healthcare robot. Because Tadashi did not have the medical knowledge needed for his goal, he also got help from Lily to create it. It is a green-colored chip with an icon of a smiling doctor and a sticker with the name of its creator on it. As long as this chip is present, any additional chips installed into Baymax will only enhance Baymax's abilities but the base personality will remain. While in the portal, Baymax removed the chip before being deactivated by Hiro. Later, Hiro discovered the chip clenched in Baymax's rocket fist while attending San Fransokyo Institute of Technology, giving him the ability to rebuild Baymax's body and using the chip to revive Baymax within the new body. In "Legacies", Hiro mass-duplicated the chip and had them inserted into the Buddy Guardians, which made the robots behave like Baymax as well. In "Trading Chips", after Mochi became stuck inside an air vent, Hiro temporarily swapped the healthcare chip with Mini-Max's chip so that Baymax, as "Mini-Baymax", could go into the vent in an attempt to rescue Mochi.
  • Fighting: This chip, created by Hiro Hamada, contains data on various martial arts styles, including karate, granting Baymax the ability to fight with these moves. This chip was red with a skull-and-crossbones drawing on it. As opposed to Tadashi's chip, which made Baymax peaceful, the fighting chip causes Baymax to become an aggressive, single-minded killing machine if the green chip is not present. This personality surfaced when Hiro removed the green chip and told Baymax to destroy Yokai, which the formerly pacifist robot carried out without question. However, Honey Lemon found the healthcare chip and reinserted it into Baymax, restoring the robot to his peaceful, nursing personality. This chip was gone along with Baymax's original body inside the portal.
  • Superhero: Following Baymax's revival, Hiro created this chip to replace the fighting chip. The chip is dark red with the silhouette of a superhero on it. This one contained fighting data, but unlike the fighting chip, it guaranteed Baymax would not succumb to violence if his original chip was removed. In addition, the chip gave Baymax information on heroic deeds.
  • Dance: Hiro created this chip to help Fred dance in his bro-tillion party. It adds a dance mode to Baymax. He can try different dancing moves and styles with it, as well as teaching them step-by-step. The chip itself has a purple-ish dark blue color and, unlike the other chips, it doesn't have any markings or logo.
  • Boost Charge: A light blue chip with a battery and bolt logo; Hiro created this chip in one night when Baymax's batteries had run out after they went on superhero duty. He inserted it the next morning with the intention of overclocking Baymax's supercapacitors to make his batteries last longer, but it gave Baymax a fast and erratic behavior. Eventually, Hiro took it out in favor of his original charging method.
  • Overdrive Mode: A blue chip with a red and purple logo; it was created by Hiro based on Karmi's fan-fiction story. It allows Baymax to change his body into "Overdrive Mode", in which he gets bigger and becomes more powerful, and his wings become capable of turning into a sword. However, the downside is that it lasts a really short time since his batteries are drained very quickly when using it. He used it to escape a special cell when Momakase trapped Karmi and the team on Akuma Island and later to scare off Orso Knox. In "Steamer's Revenge", he used it along with his submarine armor, showing that the chip can adapt to other armors besides his main one.
  • Junk Data Protocol: Hiro created this chip to clean Baymax's memory bank. Baymax managed to make the program re-write itself when it almost deleted his memories of Hiro. This chip is magenta with a trash can symbol in it.
  • Sleep Mode Protocol: A grey chip with a green insect logo; when a bot bug drained Baymax's battery, Hiro used the chip to debug him.
  • Personality: Baymax's different personalities (such as his low-battery state and overclocked state) began clashing, so Hiro used this chip for Baymax to act aptly. This chip is almost the same as Tadashi's original healthcare chip, but it is less detailed and has four badges that represent Baymax's different modes around the nurse face icon.
  • Obake: Baymax had an Obake chip secretly inserted into his access port by Noodle Burger Boy. It overrode and compromised Baymax's systems, giving Obake remote control of the robot. It also compromised Baymax's healthcare programming, which not only prevented Baymax from responding to voice activation but also caused Baymax to adopt a more menacing personality. With the chip inserted, Baymax deceived Hiro by falsely alerting him about "Obake" being detected nearby, and emotionally manipulated him into going to fight the decoy, by claiming Tadashi would've wanted him to stop Obake. After the decoy was defeated, Hiro asked Baymax how he could've mistaken the robot for the real Obake, but Baymax simply replied that he didn't know. Soon, Hiro realized something was wrong because Baymax didn't respond to his pain groans either, so he opened his chip port and saw the Obake chip, but Baymax aggressively grabbed his hand to stop him from removing it and took him to Obake's lair. When Obake's plan was foiled by Big Hero 6, Baymax continued under Obake's control, but he decided to remove the chip and allow Baymax to return to Hiro. As the lair crashed down, the chip was the last thing remaining at the bottom of the sea with no trace of Obake himself.
  • Lie Detector: This chip has a face with a long nose in it, alluding to the literary liar, Pinocchio. Hiro created this chip to enhance Baymax's capabilities of detecting lies, making him able to immediately display if someone is telling the truth or lying. And unlike conventional lie detection technology, which depends on the subject being aware that they are lying in order for the tech to discern that fact, this chip seems to bypass that limitation. Hiro later took out the chip, as turning Baymax into a lie detector wasn't his best idea.
  • Nanobot: Hiro created this chip to allow Baymax to remotely control the nanobots (nano-sized versions of microbots). It is a light purple chip with an icon of three nanobots assembled to resemble Megabot on it and has a cable that is connected to a virtual reality system used by Hiro and Baymax.
• Battle Suits: Baymax has been given different types of armors to increase his strength and usefulness.
  • Fight Armor: Baymax's initial armor which Hiro created to have him fight Yokai, since the robot's default structural design would otherwise render Baymax's installed knowledge on hand-to-hand combat useless. It was dull-green colored and was constructed using his 3D printer.
  • Super Armor: Also known as Baymax 2.0, it is an upgrade which Hiro gave to Baymax when he formed Big Hero 6. Instead of green it was made red and purple like his charging station. It added wings and thrusters, among other powerful features. It became Baymax's main armor for crime-fighting.
  • Ultra Armor: A silver armor with red parts that is made of titanium, created by Hiro so Baymax and the rest of Big Hero 6 could take on Orso Knox. In Season 2, this armor is repainted, where the silver is now black with red accents.
    • Jet Pack: An additional module that can attach to Baymax's ultra armor. It enhances the speed of flight, extends the duration of Overdrive Mode, and allowing him to maintain his flight ability in this mode. This jetpack has a seat similar to a motorcycle for Hiro to replace his magnetic pads, which are used to attach it to the armor.
  • Submarine Armor: Hiro initially built this armor for Baymax to help recover Wasabi's car from the bay. It has a sonic blaster which helps scare animals like sharks. Overdrive Mode can also be used with this armor, adapting it in a larger version (but smaller than his normal armor's Overdrive Mode), where his wings are turned upwards and uses them similarly than an icebreaker ship, and he can use his sonic blaster to rotate fast and be used like a drill/harpoon.

Alternate Forms

Dark Baymax (Kingdom Hearts Canon)

In Kingdom Hearts III, set after the events of the movie but not Big Hero 6: The Series, Baymax's original body returns, used by Dark Riku along with data from the Darkubes and the fighting chip, to see if they could create a heart from data. This had turned him into a Heartless version of the robot. Because the team's regular moves and gear have no affect on the Heartless, Hiro creates a chip with abilities and knowledge that allows Baymax to fight them, as well as to fight by Sora’s side in battle. Baymax's 2.0 armor is part of the Nano Gear Keyblade's design, along with the icon that is of his Healthcare chip, as its keychain. After Sora and Baymax fought and defeated Dark Baymax, Hiro destroyed the fighting chip that is the robot's heart, and he replaced it to restore the original Baymax to his proper nature, giving team of the Kingdom Hearts universe two Baymaxes.

Weaknesses

• Low Battery: Baymax only has a limited amount of battery charge. When he gets to very low levels, all of his capabilities are weakened and he starts showing signs of low battery power, up to and including slurred speech, decreased motor movement, visible battery indicators, and (when in his armor) an inability to fight. In addition, using his "Overdrive Mode" drains his battery faster.
• Slow Movement: While not using his armor, Baymax's movements are rather slow, which makes him vulnerable to surprise or sudden attacks.
• Vinyl Body: Because he was initially designed to be harmless, his vinyl body can be deflated or ripped easily. Yet, his exposed exoskeleton can still support getting hit.
