Big Hero 6: The Series

Big Hero 6: The Series is an American superhero animated television series that aired between November 20, 2017, and February 15, 2021. The series was produced by Disney Television Animation and was created by Mark McCorkle and Bob Schooley, also known for co-creating Buzz Lightyear of Star Command and Kim Possible. The show is based on Disney's 2014 film Big Hero 6, which itself is loosely based on the comic book series of the same name published by Marvel Comics. The series acts as a follow-up to the original film and uses traditional hand-drawn animation.

It premiered with a 43-minute episode titled "Baymax Returns" on Disney XD on November 20, 2017. In 2018, the series was moved from Disney XD to Disney Channel before the series premiere. The series formally premiered with two new episodes on Disney Channel on June 9, 2018.

The second season premiered on May 6, 2019, with a third season confirmed prior. The third season premiered on September 21, 2020, on Disney XD. The third season features predominantly 11-minute episodes, as opposed to the 22-minute episodes of the first two seasons. Cast members stated on January 28, 2021, that the series would not return for a fourth season and the series finale aired on February 15, 2021.

In December 2020, Disney announced a spinoff series titled Baymax! and produced by Walt Disney Animation Studios. The series was released on Disney+ on June 29, 2022.

Plot
The series is set after the events of Big Hero 6 (2014) and continues the adventures of 14-year-old tech genius Hiro Hamada and his compassionate, cutting-edge robot Baymax, created by his late brother Tadashi. Along with his friends Wasabi, Honey Lemon, Go Go and Fred, they form the superhero team Big Hero 6 and embark on high-tech adventures as they protect their city from an array of scientifically enhanced villains. Hiro also faces academic challenges and social trials as the new prodigy at San Fransokyo Institute of Technology (SFIT).

The show slightly contradicts the ending of the original film. Among the differences are Aunt Cass knowing about Baymax, and Hiro attending SFIT as if everything is back to normal (and though a building is erected after Tadashi, Hiro does not receive a grant from the institute). Hiro also does not come up with the name "Big Hero 6" like it is implied at the end of the movie. Instead, Fred comes up with the name after having "brainstormed an epic list of team names" and testing them with himself.

Voice cast and characters

 * Ryan Potter as Hiro Hamada, a 14-year-old robotics prodigy whose older brother Tadashi Hamada was killed in an explosion at the San Fransokyo Institute of Technology (SFIT) and member of Big Hero 6; he serves as the team's unofficial leader. He wears a suit for protection and to hide his identity when he flies on Baymax.
 * Scott Adsit as Baymax, an inflatable robot originally built by Tadashi as a medical assistant, but reprogrammed by Hiro to also use martial arts as a member of Big Hero 6; he wears a suit of armor with a jetpack and wings.
 * Jamie Chung as Go Go Tomago, a tough, athletic student at SFIT and member of Big Hero 6 who specializes in electromagnetics; she uses two large discs as wheels/skates when in action, and also uses smaller discs as weapons.
 * Genesis Rodriguez as Honey Lemon, a bubbly and optimistic student at SFIT (and Part-Time Student at SFAI or San Fransokyo Art Institute), chemistry enthusiast, and member of Big Hero 6; she uses 'chem-balls' that produce a variety of effects.
 * Khary Payton as Wasabi, a smart, slightly neurotic student at SFIT and member of Big Hero 6 who specializes in lasers, and has two laser-like blades on his arms when in action. He appreciates order and control in his life and work environment. Wasabi was previously voiced by Damon Wayans Jr. in the film.
 * Brooks Wheelan as Fred, a comic book fan and slacker who is also team mascot at SFIT and member of Big Hero 6, with reptilian super-suits (one gives the appearance of a lizard-like monster, the other is chameleon-like); he lives in a large mansion that is owned by his parents. Fred was previously voiced by T.J. Miller in the film.
 * Maya Rudolph as Aunt Cass, Hiro and Tadashi's aunt and guardian. She is obsessed with cooking new and strange dishes and is oblivious to Hiro's double life, as Hiro knows that she will "never let him out of the house" if he reveals this information.
 * David Shaughnessy as Heathcliff, Fred's family butler, who assists the team in their training efforts.
 * Alan Tudyk as Alistair Krei, a pioneer entrepreneur and CEO of Krei Tech. He is revealed to know Big Hero 6's secret identities after they saved his life in the film.
 * Andrew Scott as Robert "Obake" Aken, A mysterious supervillain who prefers to work hidden in the shadows and the main antagonist of the series. He was once a student as SFIT who had lots of ideas on how to change the world, but one of his failed experiments resulted in an explosion that broke his temporoparietal junction, leaving him unable to tell the differences between right and wrong (while also causing the left side of his face to glow purple), after that day he would then plan to destroy San Fransokyo, and rebuild it in his own image by any means necessary.

Comic book series
A comic book series based on Big Hero 6: The Series was announced to be published by IDW Publishing, making it one of the few times Marvel Comics has allowed another comic book company use their characters. The comic book series was initially titled after the film and set to be released in July 2018 from Hannah Blumenreich (writer) and Nicoletta Baldari (artist). However, the release kept getting pushed back. Since then, the comic has been retitled after the show and was released on November 13, 2019 with Blumenreich and Baldari still attached. Its follow up issues would not get released until close to a year later.

A manga series by Yen Press was released in August 2021 and is written and illustrated by Hong Gyun An. The first volume adapts the episodes "Issue 188", "Failure Mode" and "Baymax Returns Part 1", but has it feel more connected and linear.
