Professor Calamitous

From Jimmy Neutron Wiki

Professor Finbarr Calamitous (or simply known as just "Professor Calamitous" or "Calamitous") is the main antagonist of the series. He is Jimmy's nemesis, Beautiful Gorgeous' father, and Ms. Fowl's former student (despite his age).

Calamitous appears in "Professor Calamitous, I Presume," "The Great Egg Heist," "Operation: Rescue Jet Fusion," "Lights! Camera! Danger!," "My Big Fat Spy Wedding," "The Jimmy Timmy Power Hour II: When Nerds Collide," and "The League Of Villains."

Calamitous is a tiny, near-sighted, bald, short, eccentric, old, evil genius, who is one of the most brilliant and evil minds on the planet, and he'd be even more dangerous if he didn't have the bad habit of never finishing what he starts!

Calamitous is determined to get Jimmy to finish his projects for him.

Calamitous was once a little boy, who could never finish anything (not even a sentence). He later overcomes this, and he is heard completing sentences (as seen in "Operation: Rescue Jet Fusion," "The Great Egg Heist," and "The Jimmy Timmy Power Hour II: When Nerds Collide").

Calamitous also seems to like Ms. Fowl.

Calamitous wears a scientist suit, long black gloves, and eyeglasses.

Calamitous has gray hair (despite being bald).

Calamitous' catch phrase is "Umm...".

Calamitous has a robot bodyguard and disguise called the CalamiBot.

Calamitous has also been the final boss in "Nicktoons Unite!" and "Nicktoons: Attack Of The Toybots," where he faced (besides Jimmy and Timmy) Danny Phantom, SpongeBob SquarePants, and other heroes. He is voiced by Tim Curry.
