ToggleDetailed Summary
The Beginning: Hiro, Tadashi, and the Spark of Innovation
Hiro Hamada is a 14-year-old prodigy who prefers illegal robot fights over college. His older brother Tadashi encourages him to pursue something greater and introduces him to the San Fransokyo Institute of Technology. Hiro is amazed by the futuristic inventions at the lab, especially Tadashi’s project: Baymax, a soft, inflatable healthcare robot programmed to help humans physically and emotionally.
Hiro eventually creates microbots—tiny magnetic robots capable of forming anything the user imagines—earning him a scholarship. But after a tragic fire at the exhibition building, Tadashi dies while trying to save the professor trapped inside. This sets the emotional foundation of the movie.
Reawakening Through Baymax
Hiro falls into grief, isolating himself until he accidentally activates Baymax. The gentle robot becomes Hiro’s support system and leads him into a mystery: Hiro discovers that someone is using his stolen microbots for sinister purposes. This solidifies Hiro’s new mission: uncover the truth behind his brother’s death.
Building the Team
Hiro recruits Tadashi’s friends—Go Go, Wasabi, Honey Lemon, and Fred. Hiro upgrades Baymax with armor and combat programming, transforming the group into an amateur superhero team. Their quirky personalities mix with impressive abilities, forming the foundation of the Big Hero 6 squad.
They eventually uncover that the masked villain “Yokai” is using the microbots to reopen a dangerous portal-like device called a teleportation gate.
The Masked Villain Revealed
After several battles, the team discovers that Professor Callaghan, the man Tadashi tried to save, is actually Yokai. He survived the fire using Hiro’s microbots and orchestrated everything to avenge the disappearance of his daughter, who vanished during a teleportation experiment.
Hiro is enraged and nearly forces Baymax to kill Callaghan, but Baymax reminds him of Tadashi’s teachings. This moment is a crucial emotional pivot, grounding Hiro back in compassion and integrity.
Movie Ending
The climax unfolds around the unstable teleportation gate, which Callaghan intends to use to destroy industrialist Alistair Krei, whom he blames for his daughter’s loss. The Big Hero 6 team intervenes.
Inside the collapsing portal, Hiro and Baymax find Callaghan’s daughter, Abigail, suspended in hyperspace stasis but alive. They rescue her, but Baymax is damaged. In an emotional farewell, Baymax uses his final rocket fist to propel Hiro and Abigail to safety.
Baymax’s sacrifice is one of the film’s most poignant moments. Hiro returns home mourning Baymax’s loss until he discovers something hidden inside the fist: Baymax’s healthcare chip.
Using the chip, Hiro rebuilds Baymax, allowing the gentle robot to “return” with all his memories and personality. The team officially becomes the superhero group Big Hero 6, protecting San Fransokyo with newfound purpose.
Are There Post-Credits Scenes?
Yes. There is a humorous post-credit scene featuring Fred in his family mansion. He accidentally reveals a secret room and discovers that his father (voiced by Stan Lee) is a former superhero. It’s a playful nod to comic book culture and teases potential future adventures.

Film Music and Composer
The score was composed by Henry Jackman, who blends emotional orchestral themes with energetic electronic elements. Fall Out Boy’s “Immortals” serves as the movie’s signature anthem.
Filming Locations
Though animated, the conceptual “location” is the hybrid city of San Fransokyo, inspired by a mix of San Francisco and Tokyo. Developers traveled extensively to both cities to combine:
- San Francisco’s architecture, fog, and iconic hills
- Tokyo’s neon lights, signage, and futuristic urban density
This mixture is crucial to the film’s identity. It gives the movie a unique cultural flavor, visual charm, and a sense of a technologically advanced society.
