Cubert J. Farnsworth

Cubert is a clone of the Professor, created from cells scraped from "one of the shapelier growths" on the Professor's back.

He is heir to Planet Express and the Professor's fortune, being the Professor's closest living relative. He spends most of his time with the Planet Express crew criticising everything, routinely pointing out logical fallacies.

Cubert goes to school with Hermes' son, Dwight, where they are ocassionally bullied by Brett Blob, the son of H. G. Blob.

Trivia

 * Cubert was supposed to appear in A Big Piece of Garbage, but due to time constraints, he was removed entirely.

 * Cubert may be missing a toe (4ACV07).
