Fred Flintstone is a LEGO Ideas minifigure introduced in 2019 under the The Flintstones theme.
As young adults, Fred and Barney Rubble worked as bellhops at a resort. There, they meet and fall in love with Wilma Flintstone and Betty Rubble, who were working there as cigarette girls. Fred and Wilma's mother, Pearl Slaghoople, also met and took an instant dislike to each other, starting a long-lasting rivalry between the two. An unspecified amount of time later, Fred married Wilma.
Fred is a typical blue-collar worker, who works as a "bronto crane operator" at Slate Rock and Gravel Company. Fred's job title is "geological engineer".
Wilma later gives birth to the couple's daughter, Pebbles. Years later, when Pebbles is a teenager, Fred and Barney join the Bedrock police force for a time as part-time police officers. Eventually, Fred becomes a grandfather to the adult Pebbles and Bamm-Bamm's twins, Chip and Roxy. Fred's family grew again later, when he and Wilma adopted an orphaned caveboy named Stony, and despite a rough start, Fred and his new son bonded well.
