**Tadashi Hamada** (浜田 正, *Hamada Tadashi*) is the older brother of Hiro Hamada and the creator of Baymax.

## Description

*Tadashi is a good guy. He just is. He actually developed, built and programmed a state-of-the-art nursebot—a Healthcare Companion named Baymax that will likely help millions worldwide. But it's his role as big brother that makes Tadashi truly special. Every kid needs a guy like Tadashi looking out for him, and Hiro knows just how lucky he is to have him in his life.*
### Appearance

Tadashi is a tall, slender, slightly muscular young man of a larger build than others in his family. He has large, warm brown eyes and neat black hair cut above his prominent ears. His face shape is different from those of his aunt's and brother's, with a longer face, larger jaw, and slightly larger nose.

His most notable physical trait is his preference for a black baseball cap with a red-and-gold San Fransokyo Ninjas lettering on it. He is rarely seen without this cap except for a few scenes, such as when he takes off his moped helmet; it is also off in many family photos that can be seen in his home.

Since he changes his clothes daily, he does not wear anyone outfit for much longer than others. However, he owns many similar articles of clothing, only varying in color. He owns several blazers, crew-neck t-shirts, and cardigan sweaters, usually in the colors white, black, tan, red, or various shades of green. He often wears mint-colored sneakers with white soles and shoelaces and occasionally carries a tan satchel.

When he introduces Hiro to his friends, he is wearing a white crew-neck t-shirt with the artwork of a ninja (possibly a San Fransokyo Ninjas logo—notice the lowercase 'n' around the ninja's head), along with a grey cardigan, brown pants rolled up around his ankles and his mint-colored sneakers. He wears the same shirt to bed that night, with green plaid pajama pants.

On the day of his death at the San Fransokyo Tech Showcase, he wears an olive green blazer over a black shirt, with a similar pair of rolled-up brown jeans. Before he runs into the burning building, his hat falls off of his head, which Hiro retrieves and keeps as a memento.

### Personality

Incredibly kind, encouraging and hard-working, Tadashi is considered the epitome of a great brother, nephew, and student, always there when people need him. He has an energetic sense of humor and can be silly and excitable.

Tadashi is very hard-working and intellectually gifted. He does not believe in "dead ends" and values hard work to accomplish goals. He also has a large understanding of health and medicine. Ever the optimist, he successfully balances this rising career in cutting-edge technology and providing moral and emotional support for his younger brother while keeping a good attitude and a happy smile. He also even appears to be athletic and he is known to have taught Hiro some karate; Baymax's statement that Tadashi was in 'excellent health' also indicates that he is physically fit.

As the only male figure in Hiro's life, he has carried the burden of responsibility from a young age, knowing that he had to be a good role model. Having to care for Hiro alongside their aunt Cass has made Tadashi gentle and understanding, though as the big brother, he can still be rough on occasion. He is also not above scolding Hiro or becoming upset with him, getting angry at Hiro's unwillingness to try and make something of his life, showing a slightly frustrating side to his personality not seen anywhere else. He encourages Hiro to be the best that he can be and supports him in his endeavors. He was also sneaky, as he promised Hiro he would take him to a bot fight but in reality took him to his university, claiming he needed to "grab something" before they headed off in order to get Hiro to come to his university and become interested in it while technically keeping his promise of taking him to the bot fight without actually doing it.

However, he was also shown to have a silly, goofy side to himself. When he introduced Baymax to Hiro and Baymax asked if he is experiencing any pain, Hiro asked "physical or emotional", causing Tadashi to comically pout. When Hiro ran out of ideas, he told him, "Hey, I'm not giving up on you." grabbed Hiro and shook him upside down in order to shake some ideas into his head and stated that Hiro needed to "look for a new angle"―a philosophy that Hiro eventually adopts as his own during the film. He was also excitable, as shown when he was happy after finally activating Baymax (after 84 tests) and ran around and kissed Baymax.

Tadashi also values his aunt; he does not like to make her upset and is appreciative of all she has done to raise them, especially having done it alone. His concerns extend to the general public, developing Baymax with the sincere hope that the healthcare companion would help people all over the world. He is dedicated to helping others no matter what the cost is to him―a statement undeniably proven when he makes the ultimate sacrifice in an attempt to protect his teacher.

## History

 File:Hiro Tadashi SFT.jpg
One night, in the city's illegal underworld, Hiro engages himself in a bot fight against a group of thugs, specifically the boisterous Yama. After facing a humiliating defeat, Yama seeks revenge by ordering his goons to attack the young genius, who is immediately rescued by Tadashi on his moped. The brothers make their escape as Tadashi reprimands Hiro for his actions, only to find themselves caught and arrested by the San Fransokyo police. Yama and his gang are forced to share a cramped cell with Tadashi, while Hiro has a separate cell to himself due to being a minor. Tadashi was not happy with this and silently glared at Hiro across from his cell for getting them into the situation. Fortunately, they are released on account of Aunt Cass, who scolds the two on the ride home.

Frustrated with Hiro's bot-fighting obsession, Tadashi takes his younger sibling to his school, the San Fransokyo Institute of Technology, in hopes of sending him down a better path. At the Institute, Hiro meets Tadashi's closest friends (Go Go Tomago, Wasabi, Honey Lemon and Fred), Tadashi's latest invention Baymax and Professor Callaghan (an aspiring master of robotics and Hiro's personal idol). The experience successfully manipulates Hiro into having a strong desire to attend the school.

To gain acceptance into San Fransokyo Tech, Tadashi suggests that Hiro participate in the school's annual science fair. Should his invention and presentation impress Callaghan, he'll be allowed enrollment. Unfortunately, Hiro reaches a creative rut until Tadashi steps in and advises that he look from a different angle. Tadashi's advice leads to the creation of the Microbots. On the night of the fair, Callaghan shows amazement at the sight of Hiro's latest invention, leading to the latter's acceptance into the school. After the successful presentation, Tadashi and Hiro have some time alone, during which the older brother congratulates the younger one on his accomplishment, showing pride in the new path that he's willing to take.

Just then, a fire breaks loose at the school and the brothers immediately rush to the action. While most civilians manage to escape, Tadashi learns from a survivor that Callaghan is still trapped inside the burning building. With no help around to save him, Tadashi volunteers his own life. A fearful Hiro immediately stops his brother, but reluctantly allows the decision upon seeing Tadashi's humanity and motivation to rescue his mentor. After rushing inside, the building violently explodes, killing Tadashi (even though his final moments are not shown, the junior novelization implies that he was crushed by a falling beam). After Tadashi's death, the people of San Fransokyo mourn his loss while a heartbroken Hiro falls into a deep state of depression. Over time, Hiro and his friends discover that the fire was caused by Callaghan as a coverup for stealing Hiro's Microbots.

Though mentioned several times during the events following his demise, Tadashi would not appear again until after Hiro's anger, grief and frustration consume him, leading Baymax to show a series of footage (which was recorded while Tadashi was in the process of building the healthcare companion) to comfort the boy. In it, it is shown that Tadashi had struggled to perfect the robot, each attempt ending with a major failure. Although there were many setbacks, Tadashi never gave up on building him. During the eighty-fourth test, Baymax was finally functional. With Baymax working properly, Tadashi stated his eagerness to use his creation to help others, as well as sharing his success with Hiro. The footage successfully heals Hiro's damaged heart, and as such, the young prodigy vows to use his intellect to change the world for the better, which he does by defeating Professor Callaghan and using the Big Hero 6 team to selflessly protect the city.

## Etymology

* **Tadashi** - Tadashi is a Japanese masculine name. It has many meanings, but is known for meaning "righteous", "correct" or "true". Simply put, the name describes a good, honest person, fitting as Tadashi is loyal to his friends and family, and true to himself and to others. His name written in kanji is 浜田義 (*Hamada Yoshi*); the kanji 義 also means "morality", "duty", or "honor".

## Trivia

* Tadashi's role is similar to Hiro's father in the comics, Tomeo Takachiho, whose death prompted Hiro to build Baymax to fill the void left in his heart.
* Although his death was accidental, the 2013 Rotoscopers video and early information regarding the plot somewhat implies that Tadashi was deliberately murdered by Yokai in some early drafts of the script. The Rotoscopers video also depicted Tadashi as already attending classes with Hiro and was also the man in charge of a science research team (most likely consisting of Honey, Go Go, Wasabi and Fred) in which each individual would make different things and would eventually lead up to a competition.
* In the Korean dub he is renamed **Teddy Armada**.
