Roxeanne Elizabeth "Roxy" Flintstone-Rubble is the cute and pretty fraternal twin sister to Chip Rubble, the daughter of Bamm-Bamm Rubble and Pebbles Flintstone, and the granddaughter of Fred and Wilma Flintstone, and Barney and Betty Rubble.
Roxy and her twin brother, Chip, were born at the end of Hollyrock-a-Bye Baby. Roxy looks just like her mother, Pebbles, but she has white hair like her father, Bamm-Bamm, and she also inherited her father's incredible strength.
