Baymax cares. That’s what he was designed to do. Conceived and built by Tadashi Hamada, Baymax just might revolutionize the healthcare industry. But to Hiro, the nurturing, guileless bot turns out to be more than what he was built for — he’s a hero, and quite possibly Hiro’s closest friend.

Hiro Hamada has the mind of a genius—and the heart of a 14-year-old. His big brother Tadashi inspires him to put his brain to the test in a quest to gain admission to the San Fransokyo Institute of Technology. When a tragic event changes everything, Hiro turns to a robot named Baymax, and they form an unbreakable bond.

Voiced by T.J. MILLER (HBO’s “Silicon Valley,” “Transformers: Age of Extinction,” “How to Train Your Dragon 2”), fanboy FRED comes off like a laid-back dude with no direction. But this sign-twirling, monster-loving, comic-book aficionado is sure to go places—when he’s good and ready. For example, Fred doesn’t hesitate to join “Big Hero 6,” and he has a lot of ideas for his super-hero skillset, too. His ferocious, fire-breathing alter ego comes complete with claws, integrated communications and a super bounce. But his sign-spinning may still come in handy.

GENESIS RODRIGUEZ (“A24 Tusk” and “Run All Night”) was called on to help bring Honey Lemon to life. It’s elemental when it comes to chemistry whiz HONEY LEMON. Don’t let her glasses and funky fashion fool you: Honey may be as sweet as her namesake, but she has a fire in her belly and a can-do attitude that make her pretty much unstoppable. Her knowledge of alchemy proves powerful, too, when the effusive brainiac becomes part of the “Big Hero 6” and creates clever concoctions that when thrown, can get her team out of nearly any jam.
