Hiro Hamada²

Cass is the aunt of Hiro and Tadashi, who became their legal guardian following the death of the kids' parents. She is very supportive and proud of Hiro's abilities, and although Hiro knows how much Cass loves him and tries her best to continue raising him, he tends to keep many secrets from her, primarily because he knows how easily she can stress out—such as his double-life as a superhero because he knows Cass would disapprove of it due to the risks it implies, especially considering Tadashi's death. Regardless, Cass continues to teach Hiro valuable life lessons whenever she can, such as teaching him how to move on with life, getting his first (legal) job, and making new friends. Hiro and Cass also spend time together as a family by watching movies and doing other activities on certain occasions when Cass isn't busy with work and Hiro is free from schoolwork—though this is often interrupted due to his secret life with Big Hero 6.

Name: Hiro Hamada
Gender: masculine
Age: 15 years old
Family: Aunt Cass (alive), Tadashi Hamada (dead)
Appearance: Hiro is a young boy. He is 1.59cm tall and slim, with light skin, brown eyes and messy black hair. His eyelashes and eyebrows are somewhat thick, and his eyes are rounded almond-shaped. When he smiles or opens his mouth, a gap in his teeth may be noticeable along with a slight overbite. He is often found wearing a blue hooded jacket, a red shirt with a humanoid robot, dark beige capri pants, and brown sports shoes with yellow laces. Hiro's super suit is made primarily of purple with red accents and black armor, with black clothing underneath that covers most of his body up to his knees and steel-toed sneakers. On his suit are red magnetic pads, used to carry on Baymax's armor for transportation and battle purposes.

Unlike the rest of the team, Hiro's armor lacks any real capability, as his true power lies within his temper. As mentioned, however, his suit allows him to hold Baymax with magnetic pickups whenever the robot takes flight, with him on board, as well as partially protecting him from destruction. His helmet is also equipped with a communication device, allowing him contact with the rest of the team members despite their distance, if applicable. With his vast intelligence, Hiro has the power to create various new concepts and inventions, often varying in scale, from a small, but powerful, battle bot, to a state-of-the-art super suit. Not only was he able to "upgrade" himself into a crime-fighting vigilante, but also Baymax, as well as his four closest friends, creating a series of powerful battle suits with various powers and abilities; Making them a force in their own rights. Other inventions specially created by Hiro include the Microbots (which were primarily used throughout the film as a Yokai power source), Baymax's original battle suit (equipped with karate action), programming chips capable of enhancing (better or worse) the knowledge AND personality of a robot, and Baymax himself, whom the boy genius was able to recreate in every little detail by the end of the movie. In the images of Hiro and Tadashi, Hiro is assumed to know martial arts, although he is never shown using martial arts in battle.

Hiro Hamada is a young prodigy who lives in the high-tech city of San Fransokyo, along with his brother Tadashi. Hiro has intelligence beyond his age, which he rarely puts to use. Following the mysterious death of his brother, Hiro works on Tadashi's robot, Baymax, turning him into a crime fighter protecting his city. Hiro then joins forces with a group of more young intellectuals and friends of Tadashi, creating the Big Hero 6 team.

Baymax can detect vital stats, and, given a patient's level of pain, can treat nearly any ailment. Conceived and built by Tadashi Hamada, Hiro Hamada is its current owner

Baymax's overall appearance is designed to be soft, cute-looking, and non-threatening so he can assist his patients without harming them. He appears as a wide robot covered in white inflatable vinyl material, making his outward appearance resemble, as Hiro called him, a big marshmallow. However, his "true" appearance, which can only be seen by looking deep inside the vinyl, is a flexible carbon-fiber skeleton covered in plastic and wires with thick limbs holding the rest of his body together. The skeleton also has a projector in its chest for Baymax to display imagery on his outer vinyl surface. Baymax's head is relatively simple-looking, consisting of only two black "eyes" (hyperspectral cameras) and a mouth-esque line connecting them. His access port is on the left side of his chest, and can be recognized by its badge-like appearance. In it are four slots, so Baymax can hold up to four different program chips at one time. He is also capable of turning his head around 180 degrees, which is shown during the car chase with Yokai and other occasions.

Baymax also comes with a traveling case, where he will place himself inside the case and deflates, compressing his carbon skeleton into the case for convenient transport. This case is also his charging station for when Baymax runs low on power; this makes him similar to real-life robots such as ASIMO (his real-world inspiration) and Pepper (a similar robot that also likes to give hugs and fist bumps).

Go Go is a rather short, fair-skinned young woman of Korean descent with a curvaceous yet bottom-heavy figure. She has brown eyes, scruffy black bob-cut hair with violet streaks on her bangs, and makeup which consists of lavender eyeshadow, light blush, and subtle dust-pink lipstick.

In terms of attire, she is notably seen in clothing meant for fitness and physical activity. At the very least, her main clothing consists of a cropped, elbow-length, dark gray leather jacket over a white short-sleeved undershirt (sometimes replaced with a tank top that also acts as her sleepwear), black sport-shorts with red stripes on the sides, fashionably-ripped dark gray capri leggings with violet patches underneath, and a pair of black trainer-shoes with indigo-blue stripes above the white soles. She accessorizes with black bare-knuckle gloves, and a white-striped violet sweatband on her left wrist.

In her superhero persona, Go Go wears a rather close-fitting, yellow suit of armor with maglev discs on her wrists and boots (each sporting a red spot in the center) and a matching helmet, with black skin-tight underclothing with thin red linings. She is quite reserved, introverted, and sardonic, making up for her lack of conversation with irony and sarcasm.

Wasabi is, by definition, a neat freak. Cautious, neurotic, and compulsive, he is the most organized member of Big Hero 6. Out of all his friends, Wasabi is the one who would abide to the rules in a lawful and orderly manner, making him arguably the most grounded. Wasabi is methodical, running by a system for everyday life: There is a place for everything, and everything is in its place. In his field of research.

Wasabi is a tall, burly young man, creating a humorous juxtaposition with his ultimately soft nature. He is tall, very muscular and well-kept, with his most notable feature being his smooth brown locs with a yellow headband. He is also bearded, with brown eyes and a dark complexion; he appears to be mostly fond of the colors green and yellow when it comes to clothing attire. Wasabi can also be seen wearing all-black jikatabi shoes, which are often found in Japanese fashion.

When wearing his super suit, Wasabi dons a mostly green, almost turquoise armor, accompanied by what appears to be Japanese cropped pants with particular patterns layered over it. Wasabi's jikatabi fashion also remains intact with his armor, though given red linings to accompany the black.

Honey Lemon is a young Latina woman of rather tall and slim stature, even without her trademark platform shoes. She has light tan skin, green eyes and long, straight honey-blonde hair (hence her name) that reaches halfway down her back.

Her hair is often held back by some kind of headband, and she wears a pair of large magenta-framed glasses which also functions as her impromptu safety goggles. She also wears light makeup that simply consists of pink lipstick.

In terms of attire, her wardrobe consists of clothing that are 1960s and early 1970s-styled, many which are often in different bright colors such as yellows, pinks and oranges. At the very least, her usual one is a yellow headband, a long yellow cardigan-coat over a short, sleeveless, brighter-yellow dress with a white peter-pan collar and a set of white sheer tights, orange calf-length socks with frilled-cuffs, and yellow Mary Jane platform heels.

In her superhero form, Honey Lemon's costume consists of a latex, high-collared dark magenta under-suit with finger holes which is under a red-and-fuchsia armor-like dress with thin white linings, a red belt around the waist, and magenta boots with pink laces and wedge heels. She never dons her glasses, instead wearing a helmet that is the same color as her dress but with orange accents. Hung over her shoulder is her special purse for combat, in which there is a keyboard depicting the periodic table so that she can come up with a formula to create her chem-balls. Out of the team, her suit is the least armored, but this keeps her nimble and agile when attacking.

Honey is a tremendously intelligent, self-proclaimed "chemistry whiz" and an incredibly bubbly and optimistic woman. Arguably the most extroverted member of Big Hero 6, Honey is always upbeat, perky, optimistic, cute, caring and ooutgoin. She is humorously photogenic and tends to take pictures and selfies with her friends whenever she finds a moment that excites her.

Fred is a tall, shaggy, often hunched and lean young man with tawny blonde hair and blue eyes with an overall unkempt appearance. His casual outfit consists of a white long-sleeved undershirt, a light red T-shirt with a Japanese kaiju monster imprint, dark green OD cargo shorts, and white grime-covered sneakers with dark green laces. He also wears a teal hat with a monster's face and a small Kentucky Kaiju-inspired pendant around his neck.

Fred has worn similar clothes ever since he was a child, including his hat. He only changes his underwear once every few months and turns them inside out. It is hinted that his father taught him this because both said the phrase "I wear 'em front, I wear 'em back, I go inside out, then I go front and back" at the same time when Mr. Frederickson showed one of his superhero briefs.

In his superhero form, he wears a battlesuit designed after a traditional Kaiju monster, particularly his favorite kaiju Krogar. The beast's skin has the colors blue and orange with limbs of a lighter shade of blue. On its body are flame-shaped spines and a back covered in spikes. In addition to having black, spiky, claw-like nails, the suit has a tail with similar features, while its head has two sets of horns and three fierce-looking eyes (with the top one acting as Fred's access to vision). Its four-fanged "mouth" is the only opening the suit has. The soles of the suit's feet enable Fred to perform high jumps.

He is an enthusiastic comic book fan, Fred is incredibly eccentric, zany, childish, and rather boisterous. Nevertheless, he has a very lovable and friendly persona, with his own sense of humor and is extremely laid-back, especially when compared to his friends. Due to his nature, he is quite optimistic and not prone to panic easily, so he can see the brighter side of things, even in the midst of a disaster. Though the other members of the team ultimately care a great deal for Fred, they have found him to be overbearing with his erratic quirks

Hiro is a carefree and free-spirited boy with intelligence and understanding far beyond his years. Because of this, he can be a bit brazen and cocky, but never to the point of arrogance. He is easily accepting of other people and doesn't seem to have much of a problem forming positive connections with those he comes into contact with.

Despite his cool, carefree, yet hot-blooded and bold nature, Hiro has been shown to have a much softer disposition that has not been shown willingly to anyone save for Baymax and Aunt Cass such as when he felt shy when meeting Tadashi's friends. Even so, his caring and sympathetic disposition are evident both in the way he interacts with and handles his relationships with his family and team members. He is generally always looking out for the safety and welfare of those around him and taking into consideration their individual and personal conditions before finally focusing on himself, even if he suffers as a result of it. Even when Hiro is shown to have been wronged, he takes it in starkly collected stride, taking the adequate time to handle the situation with a calm, level and yet fiercely determined and driven head.

However, underneath this heart of gold lies a darker and more ruthless potential. On the flip side of this caring, loving, direct and to the point disposition, Hiro has maintained a very staunch no-nonsense policy when it comes to those who intentionally cause harm and misfortune to those he cares for and loves

On rare occasions, he gives up easily when ideas don't come to his mind immediately or makes several failed attempts. He gets nervous that he might not be good enough anymore, but thanks to his friends, he has been able to overcome these issues.
