Baymax fans will see their favorite hero once again as executive producer and distinguished superhero creator Stan Lee dropped the news that Disney and Marvel will be developing the sequel to "Big Hero 6." 

In a recent interview with the Toronto Sun, Lee divulged some of their plans for the next films under the movie studio, including that of the hit 3D animated film.

"After Ant-Man, we're going to start playing around with Doctor Strange, the Black Panther, the Inhumans, and then we have to come back for Guardians of the Galaxy 2, Big Hero 6, The Avengers, Captain America," the executive producer said. 

The news does not come as a surprise. After all, the film managed to earn $651 million internationally. It was even recognized as the highest grossing animated movie of 2014, based on the report by IGN. It also became one of the most awarded animated films for that year, including the Academy Award for Best Animated Feature as well as the Kids' Choice Awards for Favorite Animated Movie. 

But what will happen in the next installment of "Big Hero 6," which is now tentatively called the "Big Hero 7" movie? 

According to MovieNewsGuide, Hiro's brother Tadashi might have survived the lab explosion where he supposedly died, and he could return to become the main villain in the sequel. The speculation was first spotted in Day Herald, saying that Tadashi's body was not actually recovered during the big explosion. Baymax also repeatedly said the phrase "Tadashi's here." It is also reported that Tadashi will lose all his memories of his brother and Baymax and become Sunfire, who will be known as the ruthless Uncanny Avenger. 

However, it is unclear whether all the voice actors in the first film will return in the planned sequel, including Ryan Potter, Daniel Henney, Scott Adsit, Jamie Chung, T. J. Miller, Génesis Rodríguez, Damon Wayans, Jr., James Cromwell, Alan Tudyk, and Maya Rudolph.
