Disney’s 2014 success, “Big Hero 6” is getting a sequel, currently dubbed “Big Hero 7.” It will bring back the roster of heroes that audiences fell in love with, including Hiro Hamada who must battle against his older brother, Tadashi.

“Big Hero 6” had its lineup of heartbreaking moments. One very notable one was when Hiro lost his brother Tadashi, who tried to rescue his university professor, Prof. Callaghan. As viewers will remember, Callaghan eventually became the film’s antagonist after he saved himself with the help of Hiro’s microbot invention.

It is Callaghan’s own survival that has led many to believe Tadashi could have survived the flames as well. Correspondingly, it is Callaghan’s evil nature that has given fruit to the possibility that Tadashi could have taken a dark turn as well.

This theory originally came from blogger Jon Negroni, who pointed out that Tadashi’s body was never revealed in “Big Hero 6.” As such, it is very possible that his character will make his return in “Big Hero 7.”

Negroni then narrated how the explosion from the film could have been cast by a nuclear invention, which then transformed Tadashi into Sunfire. Sunfire is an original member of the Japanese manga, “Big Hero 6,” which the Disney film took inspiration from.

Eventually, Tadashi is expected to join Hiro’s team as the 7th member.

Nevertheless, “Big Hero 7” will be big hit, if “Big Hero 6” is anything to go by. After all, the film earned over US$50M (or AU$66M) in its opening weekend alone. The sequel, according to Master Herald, will be released sometime in 2017, after “Guardians Of The Galaxy 2” (April 2017) and before “The Avengers: Infinity Wars” (April 2018).

“Big Hero 7” is expected to bring back many of the original cast -- Hiro Hamada (Ryan Potter), Fred (T.J. Miller), GoGo Tomago (Jamie Chung), Honey Lemon (Genesis Rodriguez), Wasabi (Damon Wayans Jr.) and Baymax (Scott Adsit).
