His face shape is different from those of his aunt's and brother's, with a longer face, larger jaw, and slightly larger nose. He has large, warm brown eyes and neat black hair cut above his prominent ears. Tadashi is a tall, slender, slightly muscular young man of a larger build than others in his family.
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. His concerns extend to the general public, developing Baymax with the sincere hope that the healthcare companion would help people all over the world. 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. He was also excitable, as shown when he was happy after finally activating Baymax (after 84 tests) and ran around and kissed Baymax. 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. 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. However, he was also shown to have a silly, goofy side to himself. 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. He encourages Hiro to be the best that he can be and supports him in his endeavors. 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. 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 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.Īs 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. 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 has a large understanding of health and medicine. He does not believe in "dead ends" and values hard work to accomplish goals. Tadashi is very hard-working and intellectually gifted. He has an energetic sense of humor and can be silly and excitable. Incredibly kind, encouraging and hard-working, Tadashi is considered the epitome of a great brother, nephew, and student, always there when people need him. 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. But it's his role as big brother that makes Tadashi truly special. He actually developed, built and programmed a state-of-the-art nursebot-a Healthcare Companion named Baymax that will likely help millions worldwide. Official Description Tadashi is a good guy. Under Callaghan's guidance and with the funding of San Fransokyo Tech, Tadashi sought out to create useful technology that could change the world for the better―an opportunity he eventually seizes with the creation of Baymax. Tadashi was a star student at the San Fransokyo Institute of Technology, where he studied alongside his best friends ( Wasabi, Go Go Tomago, Honey Lemon, and Fred) under the tutalege of his mentor, the world-renowned Professor Robert Callaghan. Together, the two were raised by their overworked Aunt Cass in the Lucky Cat Café for ten years by the events of the film. Tadashi and Hiro were orphaned at a young age.
