Alistair Krei is the secondary antagonist-turned-anti-hero of Disney's 2014 animated feature film Big Hero 6.
He is the owner and CEO of Krei Tech Industries who is always on the hunt for the next big thing, and an occasional ally of Big Hero 6. While he is not a villain in the film, he shows a more malicious and manipulative side to himself in the series, thus making him one of the series' biggest antagonists.
