The Simpson Family
- Abraham "grampa" Simpson: Abe is Homer’s father, he lives in the Springfield Retirement Home. Abe has another "bastard" son : Herbert Powell. His wife was (and still is) a hippie, who ran away from Homer and him.
- Bart Simpson: 10-year old vandal. His teachers, parents and the rest of Springfield hold their breath if they see Bart. Every episode he has to write a line on the blackboard over and over. He likes teasing Moe on the phone, loves Krusty and collects everything that has to do with him.
Herbert Powell: Homer’s half brother. Used to be president of a gigantic auto-imperium, till he found out he was a Simpson. Homer made him lose all his money, but Maggie brought him back to the top. (Danny DeVito Guest Voice)
- Homer Simpson: 36 years old. He’s big, fat and lazy. He works in the Nuclear Power plant as a safety inspector. When he eats something, he makes this "Mmmmm....<fill in food>" sound. He drinks at Moe’s tavern. He’s incredibly dumb, he always has a different opinion than "normal people". He loves his wife and kids, except for "the boy"!
- "Jackie" Jackueline Bouvier: Marge’s mother. Old lady, who doesn’t like Homer. Her husband died in a freak roller coaster accident.
- Lisa Simpson: She’s an 8-year-old, but she’s very intelligent. She’s a number one jazz fan, and plays the blues on her saxophone as a professional, although her fingers are too stubby to become a professional.
Maggie Simpson: She wears a blue dress. She likes TV more than her brother and sister but she's pretty smart for her age (1). Some people even believe that she IS the smartest of the family. She said one word ( daddy ) except for in the Tree house of Horrors, where she once said : "What a disturbing world this is". (It was in an alternate dimesion with a possesed Maggie.)
- Marge Simpson/Bouvier: Homer’s wife, she has an enourmous haircut. She loves Homer and seems to be the only one who understands him.
- Patty Bouvier: She’s Marge’s sister and Selma’s twin sister. She smokes like a factory and she hates men, especcially Homer. But ONCE she was in love with Skinner. She does adore McGyver; though.
- Santa’s little Helper: Family Simpson’s greyhound dog.
- Selma erwilliger/McClure/Bouvier: She’s Marge’s sister and Patty’s twin sister. She has the same interests as her twin sister, except that Selma is always looking for a husband. She was shortly married to Bob Terwilliger and Troy McClure.
-Snowball I- Lisa's cat. Died when it was ran over.
-Snowball II- New cat that still lives. Black cat.
