But until Disney or Marvel confirms the release date for “Big Hero 7,” these dates are just mere speculations at this time.
Meanwhile, Tadashi Hamada, the brother of Hiro Hamada, the star of “Big Hero 6” is almost confirmed to return to the upcoming sequel to 2014’s top grossing film despite having been pronounced dead in the first film.
Hiro’s brother died in “Big Hero 6” during an explosion in a science event. But Tadashi won’t be coming back as a zombie, though.
There have already been widespread rumors in the internet alluding to the plot of “Big Hero 7.” Apparently, the “7” on the title emerged because the seventh character is going to be Tadashi.
For some reason, Tadashi survived the explosion and he will become the villain of sorts in the sequel. While he did die in the first movie, his body was never found so the writers would put a spin on the story to bring the character back to life on the sequel.
Accordingly, Tadashi was saved in the explosion by one of the inventions that were presented during the technological event. The invention that saved Tadashi has something to do with nuclear energy and that because of the power that the invention has given him, he will become Sunfire.
