Bamm-Bamm Rubble is a fictional character in the Flintstones franchise, the adopted son of Barney and Betty Rubble. He is most famous in his infant form on the animated series , but has also appeared at various other ages, including as a teenager on the early 1970s spinoff The Pebbles and Bamm-Bamm Show and as an adult in three made-for-television specials. Cartoonist Gene Hazelton contributed to the original model sheets for the character, and he has said that he based Bamm-Bamm's design on his own son, Wes.
