Montgomery Burns and Monty Burns, but usually referred to simply as Mr. Burns, occasionally as Mr Snrub, is a recurring character in the animated television series The Simpsons, and is voiced by Harry Shearer . Mr. Burns is the evil owner of the Springfield Nuclear Power Plant and is also Homer Simpson's boss . He is assisted at almost all times by Waylon Smithers, his loyal and sycophantic aide, adviser, confidant and secret admirer . </P> <P> Although originally conceived as a one - dimensional, recurring villain who might occasionally enter the Simpsons' lives and wreak some sort of havoc, Mr. Burns' popularity has led to his repeated inclusion in episodes . He is a stereotype of corporate America in his unquenchable desire to increase his own wealth and power, inability to remember his employees' names (including Homer's, despite frequent interactions--which has become a recurrent joke) and lack of concern for their safety and well - being . Reflecting his advanced age, Mr. Burns is given to expressing dated humor, making references to Jazz Age popular culture, and aspiring to apply obsolete technology to everyday life . Conan O'Brien has called Mr. Burns his favorite character to write for, due to his arbitrarily old age and extreme wealth . </P>
