Homer Simpson, voiced by Dan Castellaneta, is the patriarch of The Simpsons and is definitely the main character. Homer is an overweight, slob and a terrible father, but genuinely tries hard.
Homer previously had a job as safety inspector at Mr. Burns' Nuclear Power Plant, but good luck finding out what he's been doing for a living the last few years.

Son, a woman is a lot like a... a refrigerator! They're about six feet tall, 300 pounds. They make ice, and um Oh, wait a minute! Actually, a woman is more like a beer. They smell good, they look good, you'd step over your own mother just to get one! But you can't stop at one, you wanna drink another woman!Homer
