Guenter

Guenter is a monkey made super intelligent by the Electronium Hat which was invented by Professor Hubert J. Farnsworth. Guenter was originally an experiment to see if a monkey could pass a course at Mars University. Seemingly on top of the world, Guenter was both smart and cute making Fry extremely jealous. After Guenter's parents, a pair of monkeys possessing normal intelligence, cause a scene at a university party Guenter decides to revert to his natural state by removing the hat. When Fry, Leela and the Professor's lives are in danger, Guenter once again dons the hat with some difficulty and manages to save them all, however in doing so he falls down a massive waterfall, damaging the hat. Comfortable with the new "moderate intelligence" the damaged hat produces, he decides to abandon academic greatness in favor of business school, which the professor is not happy about. It is revealed in the end of the episode that he becomes the new president of FOX. He was raped by Amy Wong.
