The Inventor is an evil scientist who specializes in underwater vehicles, but in actuality all of his inventions are actually powered by slave children. He also uses them to do all his chores. He does appreciate their break times though. He wears a navy blue sea captain's jacket and a matching cap. (not seen in the picture)
He along with his brother (the Professor) are usually creating steampunk-like inventions and contraptions of all sorts. Although not much is known about the inventors parents so as he never references them. He also has a strong dislike for his brother, most likely because he is jealous that his invention's don't require slave labor. It has recently been anounced that Sally Syrup is The Professor's jerk daughter, making her The Inventor's niece.
