The TV series "Big Hero 6" announced that it will be led by a 1-hour TV movie called "Baymax Returns", which will be broadcast on November 20! It will be followed by a two-episode preview of the TV series, which will introduce a lot of information about the series and some short films will be released. The "Big Hero 6" series officially started airing in early 2018. "Baymax Returns" tells the story of the ending of the "Big Hero 6" movie. Hiro believes that Baymax will never come back, and he finds the chip that his brother Tadashi used to create Baymax. The 14-year-old technology genius will rebuild Baymax. But he is overconfident and always wants to take shortcuts, which puts him and the newly formed "Big Hero 6" members in trouble.
