Nimnul is a mad scientist who once worked for Aldrin Klordane.
Though Nimnul is an intelligent and creative scientist, his plans are often illogical and convoluted. For example, he kidnapped all the cats in the city to make an immense amount of static electricity and in his appearance in the pilot, he constructed a laser cannon designed to create a giant gelatin mold which would be used to cause an earthquake under the United States Gold Reserve.
For his appearance, Nimnul has receding red hair, wears very thick glasses and has a high-pitched laugh.
