Yokai (Big Hero 6)

Professor Robert Callaghan, or also better known by his supervillain name Yokai, is the main antagonist of Disney's 54th full-length animated feature film mh:greatestmovies:Big Hero 6, and a minor character in mh:besttvshows:Big Hero 6: The Series. He is a former university teacher presumed dead in a fire; until he later re-emerged using a vast army of microbots in his plan to take revenge on Alistair Krei, whom he blames for the supposed death of his daughter Abigail Callaghan. He is Hiro Hamada and Baymax's former arch-nemesis.

Bad Qualities

 * 1) He keeps up Disney's tradition of having poorly-done twist villains which are very weak and forced, similar to Hans from Frozen and Bellwether from Zootopia.
 * 2) Callaghan's reveal as the mastermind supervillain was pretty obvious considering he barely got any screen time in the first act, and Allistar Krei's suspicion would have given the twist away.
 * 3) His reveal was also out of place coming with an attempted justification for it, to the point were he feels like a Scooby-Doo villain.
 * 4) The film expects the audience to sympathize with Callaghan just because his daughter went missing, but the fact that he tried to destroy half the city for no proper reason, stole government property, and showed no pity over Tadashi's death makes it hard for us to relate with him.
 * 5) He told Hiro that Tadashi's death was his fault (which is partially true, since he did run into the fire) even though he was the one who had set the fire in anger.
 * 6) Despite his supervillain name, he was never referred to as Yokai in the movie.
 * 7) His plan involves using the typical sky beam which has been used to death in previous movies of the 2000s and 2010s.

Good Qualities

 * 1) As mentioned before, his tragic backstory about losing his daughter can make some people feel for him. Plus he did reform himself when he realized what he had done in the tv series of the same name.
 * 2) His design is kinda cool.
 * 3) James Cromwell does a good job voicing him.
 * 4) The real Yokai should have not been Professor Callaghan and could have.
