Potter’s performance captures both adolescent arrogance and profound grief. Baymax (Scott Adsit) functions as the inflatable healthcare robot created by Tadashi; Adsit’s deadpan delivery provides comic relief while maintaining the character’s programmed medical purposes.

The team rounds out with Go Go Tomago (Jamie Chung), an adrenaline junkie specializing in electromagnetic-levitation skates; Wasabi (Damon Wayans Jr.), a precision-obsessed laser specialist; Honey Lemon (Genesis Rodriguez), a chemistry expert with a perpetually optimistic disposition; and Fred (T.J. Miller), a wealthy comic book enthusiast who provides the team’s hideout.

Daniel Henney voices Tadashi Hamada, Hiro’s older brother and Baymax’s creator, whose death in a fire at the San Fransokyo Institute of Technology catalyzes the plot. Maya Rudolph portrays Aunt Cass, the brothers’ guardian. The antagonist Professor Robert Callaghan (James Cromwell) operates as the masked villain Yokai, while Alan Tudyk voices tech magnate Alistair Krei. Additional cast includes Katie Lowes as Abigail and David Shaughnessy as Heathcliff.

Big Hero 6 Sequel Status: What’s Confirmed vs. Rumored

Big Hero 6 Origins and Marvel Connection

The film derives loose inspiration from Marvel’s Big Hero 6 comics, created by writer Scott Lobdell and artist Gus Vazquez in 1998. Wikipedia’s entry details the adaptation differences.

In the original comic continuity, the team operates as a Japanese superhero group featuring Hiro Takachiho (not Hamada) and Baymax as a synthetic bodyguard with shapeshifting capabilities derived from magic rather than healthcare programming. Disney’s adaptation Americanizes the setting to San Fransokyo and reimagines Baymax as an inflatable healthcare companion, removing the magical elements in favor of hard science fiction.

This represents the first time Disney Animation adapted Marvel material following the 2009 corporate acquisition, establishing a template for future cross-pollination between the studios while maintaining distinct creative independence from Marvel Studios’ live-action universe.

Behind the Voices and Critical Reception

A Disney featurette available on YouTube explores the casting process, highlighting Scott Adsit’s methodical approach to Baymax’s monotone delivery and Ryan Potter’s chemistry with the recording booth team.

The huggable healthcare robot design required a voice that could convey warmth without human emotional inflection, creating an immediate bond with audiences while maintaining programmed detachment.
