There was a minor crossover between Joss Whedon's "Avengers: Age of Ultron" and Don Hall and Chris Williams' "Big Hero 6."
Fans know that Ultron destroyed J.A.R.V.I.S. in Whedon's "Avengers: Age of Ultron." According to Reddit user Kalean, when Tony Stark was choosing a new A.I. for his armor in the Marvel Comics film, one of his options was labeled "Tadashi."
"Big Hero 6" fans are aware that Tadashi is Hiro Hamada's older brother. Not only he was the mind behind the creation of the iconic robot-nurse Baymax, but he also enthused his younger brother Hiro to unleash his optimum potential and explore robotics at the San Fransokyo Institute of Technology, along with other intelligent students.
According to Cinema Blend, Whedon and the team could have used Tadashi as "fun" reference in "Avengers: Age of Ultron," since it was currently filming when the lead film trailers for "Big Hero 6" were seen by the public. In fact, both films are based on a Marvel comic.
Moving forward, Whedon's "Avengers: Age of Ultron" transformed J.A.R.V.I.S. into its physical form known as The Vision. The A.I. was able to conceal itself into the body Ultron had made for itself and got its new form when Thor used his lightning powers and an Infinity Stone, the Mind Stone.
With its success in the box office, there are reports saying that "Big Hero 6" will get a sequel. Meanwhile, Whedon's "Avengers: Age of Ultron" is now available for digital purchase and will hit the market on Blu-Ray and DVD on Oct. 2.
