Bamm-Bamm is the adopted son of Betty and Barney Rubble after they found him left on their doorstep. After meeting his next-door neighbor Pebbles, he falls in love with her. Bamm-Bamm's "nickname" came from a note left in the basket, causing Barney and Betty confusion over the strange name.
This was explained when Bamm-Bamm yelled the phrase "Bamm, Bamm!" and swung his club. Bamm-Bamm's excessive (and sometimes misused) strength was often a source of humor in the episodes the toddler version of Bamm-Bamm appeared in. Unlike Pebbles, Bamm-Bamm was past the crawling stage and could be seen in a few episodes trying to help Pebbles walk.
Years later, as a teenager, Bamm-Bamm attended Bedrock High School along with Pebbles and their friends, Wiggy, Penny, and Moonrock. In this version, Bamm-Bamm's super strength was not actively mentioned and was only shown on occasion. He became more passive and sensible in his manner and tended to be dominated by Pebbles' more aggressive personality. He also was the owner of a "cave buggy," a prehistoric version of a dune buggy.
As an adult, Bamm-Bamm became a mechanic, fell in love with and married Pebbles in 30 million B.C. They decided to be married in Rock Vegas where Pebbles parents were married. One of the guests seen at the wedding was Bamm-Bamm's Adoptive Great Uncle Mr. Slate. The two soon moved to Hollyrock so Bamm-Bamm could pursue his true goal of becoming a screenwriter. Later the couple had twins, Chip and Roxy.
In the 1994 live-action film, The Flintstones, Bamm-Bamm appears as a four-year-old who is adopted after Fred secretly gives money to Barney and Betty to ensure that they could afford the adoption. Bamm-Bamm is seen with long, matted, filthy blond hair and only wearing a fig leaf loincloth.
He was mentioned to have been raised by wild mastodons, a parody of various examples of inter-species adoption. This also hinted at how he had gained his incredible super-strength. Bamm-Bamm soon started to look like his cartoon counterpart after a bath, a haircut, and some new clothes.
In his famous form as a toddler, Bamm-Bamm is short with fair skin and white hair.
In the original series, The Flintstones, he wears a orange-tan or yellow-tan and black spotted loin cloth, a orange-tan or yellow-tan and black spotted hat and a brown or black strap with a white bone.
As a 15 year-old teenager in the spin-offs, The Pebbles and Bamm-Bamm Show and The Flintstone Comedy Hour, he is tall, muscular and his hair style is still the same and wears a mustard-yellow turtle-neck short-sleeved shirt, dark moss green and black spotted shorts and a turtle shell hat.
