Atrocia Frankenstone made her official debut in 1979 in the episode "Fred and Barney Meet the Frankenstones" from The New Fred and Barney Show where her father Frank and the rest of the family just moved to Bedrock and opened up their own condominium which they dubbed the Deadrock Arms Condorstonium that was home to a large gaggle of monsters.
In 1980, Atrocia along with the Frankenstones starred in the primetime special, The Flintstones' New Neighbors. Later, Atrocia along with her family finally received their own animated segment in The Flintstone Comedy Show focusing entirely around them. Four years later, the Frankenstones made their final animated appearance in The Flintstone Funnies, however the show was mostly repackaged segments from The Flintstone Comedy Show.
