When Hiro visits the university for the first time, he is star-struck by the world-renowned roboticist—while Callaghan immediately sees the potential in the 14-year-old prodigy, encouraging him to put his brain to better use. He later convinced Hiro not to sell Krei any of his Microbots, in which Hiro declines Krei, he later starts a fire and steals the Microbots in which Hiro's Brother tries to save him, but it kills Tadashi, and Callaghan fakes his death (which means he used the Microbots to escape).
During the recreation of Hiro's microbots, and then tries to kill Hiro and Baymax for witnessing his creation, he later tries to Kill Wasabi, Fred, Honey Lemon, and Go Go for witnessing his Microbots to bring in a mysterious part of a certain machine as if he plans to use it for something classified. On a Quarantine Island The Gang unearth's a project called "Silent Swallow" which is what Callaghan was once a part of with his daughter Abigail, when he was exposed, he expressed that Tadashi was a fool to try to save him.

But the Big Hero 6 interferes and then he was arrested by the law, and as he sees his daughter being carried into the ambulance Alive, he then realizes he has dishonored his daughter and himself by the crimes he had committed.
