He was the local bully in Bedrock and also at Bedrock Elementary School, who was always out to get Freddy Flintstone and his friends along with his three lackeys Tarpit Tommy, Janet Granite, and Flab Slab, and his pet dogasaurus, Stalagbite.
He is a short and muscular cave-boy with fair skin, thick black eyebrows, black eyebrows, brown hair with an orange and black-spotted hairband and a protruding tooth on his lip. He wears a mustard-tan loin cloth with a black string belt that is held together by a white bone and orange and black-spotted wristbands.
- In two episodes, "Rocky's Rocky Road" and "The Big Bedrock Bully Bash", he made some rare attempts to be nice to Fred and the gang.
- In three episodes of the first season, "The Fugitives", "Freddy's Rocky Road to Karate", and "Freddy's First Crush", Miss Rockbottom called him by his real name, Francis, but in the episode of the second season, "Rocky's Rocky Road", his mom called him Rockford, which he seemed to be more embarrassed about than the latter.
- Rocky and his friends seem very out of character in "Dino Come Home", as they are cheering in the bus along with the other kids and want to help Freddy find Dino. However, no personal lines are written for them, so this may be a lack of attention by the animators.
