The Main

Pretty much The Hero without being, y'know, a hero.

The one the story focuses on more than anyone else in it. They might be the person the media is named after because of how main they are. They're part of the Main Group or Family and are usually seen as a little more "important" than everyone else, meaning the other characters in The Main Group don't have as much screen time or background as The Main.

The Main is, as their title insists, the main character, so we see life through their eyes the most. We see them through their day-to-day life, at school or work, and out in the community interacting with the Secondaries.

Examples of The Main
Family Guy - Peter Griffin: The spectacled, overweight, misadventure-having American father is the most prominent character in his show, appearing in just about every episode. Rivaled with Homer Simpson of The Simpsons, Peter is seen going on many comical journeys along with his friends and family, some arguably more fun than what The Simpsons had even in its earlier life. Peter Griffin just might be THE family guy the show's referring to in its title.

SpongeBob SquarePants - SpongeBob SquarePants: This little sea sponge showed up in every episode of his show from seasons 1 to 11. He's been on many adventures, has many friends, and is known by everybody in Bikini Bottom in some way, let it be a friend, an employee, an annoyance, or just a casual acquaintance.

The Simpsons - Homer and Bart Simpson: Some argue that Homer is the main character of The Simpsons as he is the man of the house, the worker of the family, and the only one to have appeared in every single episode in some form, also meaning he's the most prominent character in the entire show. However, Bart is the most popular character from The Simpsons as he's appeared in every season at least once, had his own -Mania , has many pieces of merchandise in his name, and featured in every Simpsons video game. Bart is also considered by some to be the Mascot for his show, not his father.
