Bamm-Bamm Rubble (sometimes spelled Bam-Bam Rubble[8]) 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 spin-off The Pebbles and Bamm-Bamm Show and as an adult in three made-for-television movies. 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.[9]
