Charles Montgomery Burns (a.k.a. Mr. Burns, C. Montgomery Burns, C. M. Burns, Monty Burns, and Burnsie). He is the owner of the Springfield Nuclear Power Plant (SNPP) and Homer Simpson's boss. He is attended to at almost all times by Waylon Smithers, his loyal aide, advisor, confidant and secret admirer.
Mr. Burns is Springfield's richest and most powerful citizen, with an estimated net worth of $16.8 billion. He uses his power and wealth to do routinely what he wants without thinking of consequences or interference from the authorities. Although originally designed as a one-dimensional recurring villain who might occasionally enter the Simpsons' lives and wreak some sort of havoc, Burns' popularity has led to his repeated inclusion on the show. He embodies a number of stereotypes about Corporate America. He has an unquenchable desire to increase his own wealth and power. Mr. Burns also embodies the stereotypes of a manager. He forgets his employees' names and is unconcerned for their safety and well-being. His favorite expression is the word "Excellent", muttered slowly in a low, sinister voice while tenting his fingertips. Mr. Burns was born on September 15, but the year of his birth is uncertain. It has fluctuated during the course of the show, being explicitly stated as young as 81 in Simpson and Delilah and as old as 104 in Who Shot Mr. Burns? Part I and A Hunka Hunka Burns in Love. In the episode Fraudcast News, originally aired in 2004, Burns states that he was born in 1889. He is occasionally referred to as "Springfield's oldest resident". Frequent allusions to Burns' age place his date of birth in the late 19th century. He had a drivers' license which expired in 1909, he graduated from Yale University in 1914, and was depicted in a 19th century Woodcut as terrorizing children. Once, he forgot his password, and when he asked Smithers, he was answered by "your age." You hear four beeps when he enters his code. Also, Burns was enemies with General Tso, who lived in the 19th century.
Mr Burns will appear in the 2017 cartoon crossover, Castaras. As a villian, and the main villian to Lisa Simpson.
