Professor Calamitous



Professor Finbarr Calamitous was Jimmy's most recurring nemesis on The Adventures of Jimmy Neutron: Boy Genius animated series. He was a former student of Retroville Elementary, famous for never finishing anything he did, such as inventions, his lunch, and even his own sentences.

Personality
Calamitous, much like stereotypical evil geniuses, while incredibly smart and evil, can also be somewhat comedical and absent-minded. His problem of forgetting things is always used to the heroes' advantage, and while he did go through shock therapy to cure himself, his problem somehow came back during the events of Nicktoons Unite!, as his defeat was because he forgot to make the Doomsday Machine with solar panels instead of plugs, which were turned off by Spongebob. While he does love his daughter, Beautiful Gorgeous, he is always trying to get her to be evil like him, instead of just letting her do it her way, which creates some conflict between the two.
