Possible Opponents[]


Calamitous was an intelligent individual, yet he could never finish anything. His inability to finish things lead him to never finishing his homework as noted by his former Elementary School teacher, Ms. Fowl, which strengthens the idea he was held back. After some time, Calamitous seemingly vanished from public view.

He later reappeared after discovering the existence of a child genius in Retroville who goes by the name of Jimmy Neutron and subsequently attempted to enlist him in finishing his inventions, but utterly failed. Calamitous then devoted his life to defeating Jimmy Neutron and attempt to take over the world afterwards.
