RoleMain
Fred, the protagonist of the series and the father and husband of the titular family, operates a bronto-crane - a Brontosaurus used for excavation - at the Slate Rock and Gravel Company. He is accident-prone, overweight, and enjoys consuming large quantities of food that may not be entirely healthy. Despite being prone to anger, often over trivial matters, he is a devoted spouse and father. Fred is skilled at bowling and is a member of the all-male "Loyal Order of Water Buffaloes" Lodge No. 26, which serves as a fictional equivalent to real-life fraternities like the Loyal Order of Moose. In season one, it was revealed that Fred's catchphrase, "Yabba Dabba Doo!", is the Lodge's official cheer.
As Fred's spouse and Pebbles's mother, she possesses greater intelligence and level-headedness than her husband. However, she has a tendency to spend money, often exclaiming her catchphrase, "Da-da-da duh da-da CHARGE it!!" together with her friend Betty. Although she frequently serves as a contrast to Fred's bad behavior, she remains fiercely loyal to him. She is also a highly jealous individual, and the mere suggestion of another woman, especially an attractive one, interacting with Fred quickly incites her anger.
Towards the conclusion of the third season, the youngest daughter of the Flintstones, known as Pebbles, makes her debut. Her typical attire consists of a hair bone to secure her ponytail, a shirt with a color combination of light green and black, and a turquoise and black diaper. Similar to her kin, Pebbles opts not to wear footwear or pants.
Although the Flintstones' pet saber-toothed cat is seldom seen in the main show, it consistently appears during the end credits where it tosses Fred out of the house. As a result, Fred is compelled to knock on the front door incessantly and shout "Wilma!" at the top of his lungs, causing a commotion in the entire neighborhood.
Fred's best friend and next-door neighbor, who is a prominent secondary character in the show, is almost six inches shorter than Fred and is also overweight. Although his occupation is unknown for most of the series, he is later shown to work at the same quarry as Fred. Like Fred, he enjoys bowling and golf and is a member of the Loyal Order of Water Buffaloes. Despite their occasional quarrels, which are usually a result of Fred's short temper, their strong fraternal bond is always evident.
Mr. Slate is Fred and Barney's boss at the gravel pit who fires and rehires Fred throughout the series. He has an ever-changing first name and is the founder of the Slate Rock and Gravel Company, which is still in business two million years later, operated by his descendant George Slate the Eighty-thousandth. In the early episodes, he was known as Mr. Rockhead and was a supervisor of Fred, but the two characters eventually switched identities and the shorter character faded away.
The Great Gazoo, a character from the Flintstones, is an alien from the planet Zetox who was banished to Earth. He possesses the power to warp reality and often helps Fred and Barney without their consent. Despite being from the future, he is unhappy with being sent back to the Stone Age. Only Fred, Barney, Pebbles, Bamm-Bamm, small children, Dino, and Hoppy are able to see him. Gazoo was introduced in the final season of the show.
RoleSupporting
Throughout the Flintstones series, Wilma's hard-to-please mother serves as Fred's mother-in-law and Pebbles' grandmother, constantly criticizing Fred's behavior. She was introduced without a last name in seasons two and three, and had a brief reconciliation with Fred in one episode. However, their relationship ended again after she discovered Fred had swindled her out of money. In a flashback episode, she was identified as "Mrs. Slaghoople," and her name was later changed to Pearl. In the 1993 TV movie, they reconciled once again after a tumultuous history.
The Rubbles acquire a pet hopparoo, a hybrid creature of kangaroo and dinosaur, at the start of the fifth season. Initially, Fred and Dino mistake him for a gigantic mouse, causing some fright, but they eventually form a close bond after Hoppy comes to their aid in an accident. He also doubles as a babysitter for the kids by carrying them in his pouch, which Betty uses as a shopping cart.
Joe is a mutual friend of Fred and Barney who is often mentioned by Fred when they have an argument. Joe was once the fire chief of the Bedrock Volunteer Fire Department and his appearance changed throughout the series. However, his appearance in "The Picnic" episode was the most commonly used.
Uncle Ghastly is Gobby's towering uncle from Creepella's side of the family, usually depicted as a large furry hand with claws emerging from a small door, well, or wall. In their first appearance, his shadow gave viewers an idea of his appearance. He wasn't named until his second appearance.
