Which Disney film features the character of Yokai?

The Disney film featuring the character Yokai is Big Hero 6.

Released in 2014, Big Hero 6 follows robotics prodigy Hiro Hamada and the healthcare companion robot Baymax. After a devastating fire, Hiro discovers that the masked villain Yokai is using swarms of microbots and advanced technology to pursue a dangerous revenge plot. This crisis leads Hiro to work with Baymax and a group of friends who become the superhero team Big Hero 6.

Yokai’s identity is Professor Robert Callaghan, a respected scientist and dean at the San Fransokyo Institute of Technology. Callaghan becomes consumed by anger after his daughter Abigail disappears during a teleportation experiment created by industrialist Alistair Krei. He blames Krei and secretly adopts the Yokai persona while rebuilding the teleportation system.

The character is sometimes confused with a figure from Marvel’s original Big Hero 6 comics. Disney substantially reworked the setting, characters, and supporting cast for its animated adaptation. The film combines superhero action with themes of grief, invention, responsibility, and choosing compassion over revenge.
