Cubert J. Farnsworth

Cubert Farnsworth is a clone of the Professor, created from cells scraped from "one of the shapelier growths" on the Professor's back. He and the Professor refer to their relationship as one between a father and son.

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 Wozniak Nerd Academy with Hermes' son, Dwight, where they are occasionally bullied by Brett Blob, the son of H. G. Blob.

In August of 3010 of the first universe and probably the second, he grows up and marries Leela between 3030 and 3050, but later they get divorced and he is paid alimony. In the third universe, however, Fry, Farnsworth and Bender return in their time machine and all gets back to normal.

Personality
At first Cubert didn't want to follow in Hubert Farnsworth's footsteps and become a scientist, thinking that scientists were useless. However he eventually changed his mind and said he wanted to be just like Hubert. Though he was a clone, Cubert and Hubert acted as though they were father and son. Cubert's best friend was Dwight Conrad.

Cubert was uncool and unpopular among other children and was often picked on by Brett Blob. At one point, he and Dwight attacked Brett with salt which affected the slimy alien in a similar way it affected a slug, though Brett was able to recover from it before long. Cubert was also often nasty and derisive to the other members of Planet Express, frequently pointing out their flaws in a nasty manner or insulting them just for the sake of it.

Family

 * Professor Farnsworth, identical DNA, "father".
 * Philip J. Fry, many-times-great uncle, many-times-great grandfather.
 * Igner, genetic son, "brother".
 * Dr. Zoidberg, godfather.

Production
Cubert was originally supposed to appear in "A Big Piece of Garbage", but his appearance in that episode would have made the episode at least an hour long. Cubert's purpose was originally to appear in almost every episode, constantly pointing out flaws in the logic of the Futurama universe (such as odour travelling through space or flying faster than the speed of light), but even the writers got annoyed with this and feared the audience would despise him beyond his intention.

His character developed further in "The Route of All Evil" and "Bender Should Not Be Allowed on Television", distancing from his original purpose of pointing out flaws to be a real child representation of the Professor.

Trivia

 * Cubert may be missing a toe (4ACV07).
 * The rest of the characters have progressed in some way, i.e: The Professor saying he is 165 in Bender's Game as opposed to 160, Cubert remains the exact same as in his first appearance.
